Lessons Learned From the Banking Industry DDoS Attacks: Good Advice Worth Heeding

Now that the banking industry has gone through four rounds of very public DDoS attacks, experts are looking at what happened to extract some “lessons learned” to turn this negative into a positive. Even if your business isn’t a financial institution, there’s good advice here that’s certainly worth heeding. Lesson One: No matter what industry or business you’re in, you need to have a plan in place to defend your business. DDoS attacks are not just hitting the banking industry. If your business has competitors that would benefit from your website being down, then you are vulnerable. Since it’s possible to buy DDoS as a service, anyone can launch an attack against you for as little as $10. Lesson Two: Don’t wait for an attack to put a solution in place to defend your company. Once an attack starts – and it could happen at any time – your organization’s website could be completely out of commission for an extended period. Why risk downtime when it’s easy enough to put a solution in place today? The solution could be on premise, in the cloud, or a hybrid combination. Lesson Three: Get a dedicated DDoS solution. Don’t count on traditional security devices like firewalls and IDS/IPS to protect your business because they just aren’t designed to handle modern DDoS attacks. When you choose a solution, consider that the volume level of attacks has been getting bigger, and the attacks have grown more sophisticated. Get a solution that meets today’s needs. Lesson Four: Create a detailed incident response plan. Know what to do if/when an attack occurs and assign tasks to specific people to avoid delays in responding. Lesson Five: If your organization is hit by an attack, closely monitor for indicators of compromise (IOCs). Many experts believe that DDoS attacks are smoke screens for fraud and other types of attacks that are designed to steal money or intellectual property. Lesson Six: Be willing to share information. DDoS attacks have been widespread and businesses, solution vendors and law enforcement agencies are better together than individually. If we look at what happened with the banking industry attacks, it got easier to defend against them once all types of organizations collaborated with each other to share intelligence, profiles of the attacks and mitigation strategies. Lesson Seven: This is more of a prediction than a lesson learned. Experts predict that critical infrastructure such as utilities, transportation systems, pipelines, the electrical grid, etc., will be targeted for DDoS attacks at some point. Attackers have the ability to target industrial controls as well as business websites. Administrators who control critical infrastructure need to re-read lessons one through six and take them to heart. Source: http://www.securitybistro.com/?p=8023

Lessons Learned From the Banking Industry DDoS Attacks: Good Advice Worth Heeding

What’s Next for DDoS Attacks?

Sept. 18 marks the one-year anniversary of Izz ad-Din al-Qassam Cyber Fighters’ first announcement about distributed-denial-of-service attacks to be waged against the U.S. financial services industry This self-proclaimed hacktivist group, which U.S. government officials have suggested is being backed by the Iranian government, has for the last 12 months targeted the online banking platforms of nearly every top 100 U.S. banking institution. The group has claimed it’s attacking U.S. banks because of outrage over a YouTube movie trailer deemed offensive to Muslims. The group’s attacks against banks for the last several months have been unsuccessful at taking sites down. And its Phase 4 campaign is in a lull. Still, experts caution banking institutions against letting their guards down. And they warn that the government, media, healthcare and energy sectors could be among the next targets. That’s because banking institutions have enhanced their defenses, so other sectors are easier targets. Some experts, including McAfee Labs and Arbor Networks, expect that al-Qassam could join forces with the Syrian Electronic Army, a collective of attackers that supports Syrian President Bashar al-Assad, to attack a variety of U.S. websites. Experts urge organizations to update their DDoS defenses. Botnet Remains Strong Scott Hammack CEO of DDoS-mitigation provider Prolexic, says that despite the recent lull in al-Qassam’s attacks, there’s no indication that the group’s botnet, known as Brobot, is waning. “We have validated thousands of infected web servers that can potentially participate in future campaigns. We still don’t see the scale of the attacks we saw five months ago, but we are definitely seeing a lot of probing,” he says, which suggests more attacks are on the way. DDoS attacks over the last five months have not been as large, but that should not be misinterpreted to mean Brobot has been retired, Hammack says. “Maybe Iran, with their new leaders, are saying ‘Cool off a little bit.’ But the gun is still loaded. They still have the arsenal at their disposal; they just haven’t fired it in a while.” If al-Qassam were to unite with other cybergroups, such as the Syrian Electronic Army, it could mark a new era of cyberwarfare against the U.S., experts say. “We have to realize this is cyberterrorism,” says Ashley Stephenson, CEO of Corero Network Security. “The disruption, the publicity, the nuisance, the investment these banks have to make … the success of terrorism is not just the act itself, but the amount it costs the victims [for defenses],” he says. Banking institutions and those in other sectors have to continually enhance and update their DDoS defenses, he says, “so that no one needs to panic on the day of an attack” Training Ground al-Qassam’s attacks have served as a training ground for other attackers, says Dan Holden of DDoS-mitigation firm Arbor Networks. “In terms of DDoS in general, we will see more DNS amplification attacks. It’s not that difficult,” he says. A DNS amplification attack relies on a much larger list of DNS servers to amplify the attack. “The attackers are going to have to get better and bigger to take anyone down,” Holden says. That’s because DDoS defenses have improved across the board, although some industries, such as banking, are further along in their mitigation strategies than others, Holden explains. The real question about al-Qassam’s future is not how its attacks might be waged, but rather who will be the target, he says. Holden says he doesn’t see the attacks themselves changing; but the targets will change. “I would be surprised if they continue attacking the banks,” he says. “At this point, what is the point? Something’s got to change.” Cyber-attackers Unite? Because the Syrian Electronic Army and al-Qassam both have waged DDoS attacks to gain attention for their social and political causes, some experts expect them to join forces. While al-Qassam has focused on banks, the SEA’s primary targets have been media and government sites, according to McAfee Labs . Now, DDoS experts, including McAfee Labs, argue both groups have similar interests in taking down U.S. sites, and by joining forces, they could use Brobot for a renewed purpose. One industry expert, who asked not to be named, says the distinction between the SEA and al-Qassam has increasingly blurred. “Isn’t the Syrian Army likely the same guys as al-Qassam? And if you look at the geopolitical stuff, the two align,” this expert says. “They’re holding off attacks because they’re waiting to see what happens with Syria, frankly. And the banks are defending well, so they will move on to a new target. Besides, using the movie as an excuse for attacks is not effective or really being believed anymore.” “The Syrian Electronic Army has said quite clearly that if the U.S. does anything [as far as military strikes] they are coming after us,” Arbor Networks’ Holden says. “And if there is any sympathy for that, it’s a great excuse for QCF [al-Qassam Cyber Fighters] to repurpose and retool their botnet for something else. They could jump onboard there. This is the perfect excuse to change the story about attacking because of the video. This is the perfect cover.” If forces do unite, Holden says other critical infrastructure sectors, beyond banking, will likely be targeted, possibly defense contractors, rather than government itself. “I don’t foresee government being a target, but, instead, a weaker vertical,” Holden says. “If anything government-focused were to be attacked, I would think it would be government contractors that would be somehow associated with Syria.” Holden says e-commerce sites also could be prime targets. “[Those sites] are obviously related to capitalism, like the banks, and the money lost would be huge,” he says. “The impact would be very real, given how much commerce occurs over the Internet.” Media sites could be another target, Holden says. Regulatory Oversight Because of ongoing DDoS threats, more regulatory and legislative oversight related to how critical infrastructure industries address DDoS risks is likely on the way, says Corero’s Stephenson. “The attacks have heightened the need for guidance or legislation, whether that’s from the SEC [Securities and Exchange Commission] or an international agency like the European Commission,” he says. The need for more regulation and cross-industry collaboration has been highlighted by al-Qassam’s attacks, Stephenson adds. DDoS attacks have become a part of everyday business, and all sectors should be sharing threat intelligence, Stephenson says “One of the things I took away from this last year is that the banks really have learned a lot,” he says. “This type of cyberthreat is now business as usual. This is going to be a continuous threat and an ongoing risk of doing business online, and I don’t think we’re going to win here by keeping attack information secret.” The more organizations disclose about the attacks they suffer, the stronger defenses can be built, Stephenson says. “That’s where the vendors come in,” he says. “When they have an attack that is defeated, they can put the information together and pass that on to the authorities. A year ago, that wasn’t happening like it is today,” and there’s always room for improvement. Source: http://www.bankinfosecurity.com/whats-next-for-ddos-attacks-a-6074

SatoshiDice hit by DDoS attack, but bets continue

Bitcoin gambling site SatoshiDice has recovered after being felled for several days by a DDoS attack. The site went down several days ago, and was inaccessible from the Internet. Erik Voorhees, who created the site and sold it for $11.5 million in July, no longer runs the site, but naturally still has insights into how it operates. DDoS attacks happen a lot to bitcoin gambling sites, he said. “They largely wasted their money,” he said of the attackers, pointing out that the website isn’t needed for the placing of bets. It simply provides information about bet statistics, and bitcoin addresses to send to. These addresses are constant, available outside of the main site, and can easily be retained by regular gamblers even when the site goes down, meaning that bets can still be processed. “They’d have to launch an attack against the whole bitcoin network,” Voorhees said. There is a back-end computer processing the bets, but this isn’t the same computer that hosts the website. Attackers could potentially disrupt betting if they were able to find that machine, but Voorhees points out that it could easily be moved. The attack didn’t seem to affect the site’s popularity in the long term. SatoshiDice vanity addresses made up eight of the most popular bitcoin addresses used on the network overnight.

Cybercrooks use DDoS attacks to mask theft of banks’ millions

Distributed denial of service attacks have been used to divert security personnel attention while millions of dollars were stolen from banks, according to a security researcher. At least three US banks in recent months have been plundered by fraudulent wire transfers while hackers deployed “low powered” DDoS attacks to mask their theft, Avivah Litan, an analyst at research firm Gartner, told SCMagazine.com. She declined to name the institutions affected but said the attacks appeared unrelated to the wave of DDoS attacks last winter and spring that took down Web sites belonging to JP Morgan , Wells Fargo, Bank of America, Chase, Citigroup, HSBC, and others. “It wasn’t the politically motivated groups,” she said. “It was a stealth, low-powered DDoS attack, meaning it wasn’t something that knocked their website down for hours.” Litan described the attack method in a blog post last week that warned banks’ losses could have been much greater. “Once the DDoS is underway, this attack involves takeover of the payment switch (eg, wire application) itself via a privileged user account that has access to it,” she wrote. “Now, instead of having to get into one customer account at a time, the criminals can simply control the master payment switch and move as much money from as many accounts as they can get away with until their actions are noticed.” Litan, an expert in financial fraud and banking security, did not describe how attackers gained access to the wire payment switch at banks, but she offered banks advice on how they might better protect themselves. “One rule that banks should institute is to slow down the money transfer system while under a DDoS attack,” she wrote. “More generally, a layered fraud prevention and security approach is warranted.” Security researchers have previously highlighted the growing trend of using DDoS attacks to hide fraudulent activity at banks. The Dell SecureWorks Counter Threat Unit issued a report (PDF) in April to warn that a popular DDoS toolkit called Dirt Jumper was being used to divert bank employees’ attention from attempted fraudulent wire transfers of up to $2.1 million. In a joint statement (PDF) issued last September with the Financial Services Information Sharing and Analysis Center and the Internet Crime Complaint Center, the FBI warned that the $200 Dirt Jumper toolkit was being used as a smokescreen to cover fraudulent wire transfers conducted with pilfered employee credentials. “In some of the incidents, before and after unauthorized transactions occurred, the bank or credit union suffered a distributed denial of service (DDoS) attack against their public Website(s) and/or Internet Banking URL,” the report said. “The DDoS attacks were likely used as a distraction for bank personnel to prevent them from immediately identifying a fraudulent transaction, which in most cases is necessary to stop the wire transfer.” Source: http://news.cnet.com/8301-1009_3-57599646-83/cybercrooks-use-ddos-attacks-to-mask-theft-of-banks-millions/

DDoS is Back; 3 Banks Attacked

A week after the self-proclaimed hacktivist group Izz ad-Din al-Qassam Cyber Fighters announced plans to launch a fourth phase of attacks against U.S. banks it’s still not clear whether the group has resumed its distributed-denial-of-service activity. DDoS attacks appear to have targeted three banks July 24 through July 27, according to Keynote, an online and mobile cloud testing and traffic monitoring provider, and other sources. But security vendors that track attacks linked to al-Qassam’s botnet, known as Brobot, say they’re uncertain exactly who was behind those attacks. While some attack evidence suggested a link to Brobot, nothing was definitive. The online banking sites of JPMorgan Chase, U.S. Bancorp and Regions Financial Corp. all experienced intermittent outages last week, Keynote says, and the outages appear to be DDoS-related. All three banking institutions have previously been targeted by al-Qassam. Those three banks all declined to comment about the outages, although Chase did acknowledge intermittent online issues July 24 on Twitter , in response to customer complaints. Detecting those online glitches, however, took some digging, says Aaron Rudger, Keynote’s Web performance marketing manager. The online traffic patterns were different from what Keynote has recorded in the past for activity believed to be related to DDoS, he says. “Normally with DDoS attacks, we see a ramping decline in a site’s performance as the load against it builds,” Rudger says. “Eventually, the site falls over when overwhelmed.” But in all three online outages tracked last week, that pattern was not present, he says. “It seems they were hit very hard, very fast – so fast, our agents did not observe the typical ‘ramping’ effect of an attack,” he says. The pattern divergence could signal a different type of DDoS approach, or merely be a byproduct of the steps the affected banking institutions were taking to mitigate their outages, or a combination of the two, he says. And while all three banks suffered slightly different types of attacks – Chase hit by DNS lookup errors, U.S. Bank hit by TCP connection errors and Regions hit by traffic that allowed access to its homepage but kept eBanking inaccessible – Rudger says they all were, at least in part, linked to external issues. Bot Activity The outages linked to Chase began during the morning of July 24, stopped and then picked back up in the afternoon, says one DDoS mitigation expert, who asked to remain anonymous. The first wave of attacks had no commands linked to Brobot, but the second wave did, the source says. The outages at U.S. Bank, which began during the very early morning hours of July 24, also stopped for a while and picked back up in the afternoon, Rudger says. And the outages at Regions showed similar patterns, though the outages spanned two days and eBanking remained inaccessible throughout the duration, he adds. John LaCour, CEO of cybersecurity and intelligence firm PhishLabs, declined to comment about any particular banks affected by DDoS activity, but he confirmed that his company had tracked new attacks. He did not say, however, if those attacks were linked to Brobot. Tracking Attacks Several other DDoS mitigation providers would not comment about last week’s three apparent DDoS attacks. But the anonymous source says no one is certain whether al-Qassam is connected to those attacks. After al-Qassam’s announcement that it planned to launch a fourth phase of attacks, copycats may have decided to take advantage, launching attacks of their own hoping to be mistaken as al-Qassam, the source says. The group hasn’t attacked since the first week of May, when it announced it was halting its DDoS strikes in honor of Anonymous’ Operation USA , bringing an end to its third phase of attacks, which began March 5 (see New Wave of DDoS Attacks Launched ). al-Qassam has repeatedly stated it’s waging its attacks against U.S. banking institutions in protest of a Youtube movie trailer deemed offensive to Muslims. “Other DDoS actors have started their hostilities, trying to blame (or at least be confused with) them on QCF,” the source says. “We saw similar activity from the middle of Phase 2 onward, where fraudsters were attacking known [Operation] Ababil targets in order to straphang on the chaos that QCF was bringing.” Several security vendors tracking the group’s Brobot say that the botnet is growing. “The huge number of servers controlled by the attackers shows that this campaign was fully planned, intentionally organized and deliberate,” says Frank Ip, vice president of U.S. operations for NSFOCUS, which tracks DDoS activity. “This leads us to wonder whether the attack campaign is supported or backed by a country or financially well-off organization behind the scenes. We expect that similar DDoS attack events will occur in the wake of the recent activity, employing more diversified and varying methods.” Source: http://www.govinfosecurity.com/ddos-back-3-banks-attacked-a-5951/p-2

DDoS: Lessons From U.K. Attacks

While U.S. banking institutions brace for the next wave of distributed-denial-of-service attacks by Izz ad-Din al-Qassam, new cyberthreat research reminds us that no industry or global market is immune to DDoS. A new study from online security provider Neustar shows that DDoS attacks are up in the United Kingdom, just as they are in the U.S., and they’re targeting everything from e-commerce sites to government. It’s not just banking institutions that DDoS attackers want to take down – a truth we’ve been preaching for several months. But now, data proves it. Of the 381 U.K. organizations polled between May and June by Neustar, 22 percent said they suffered from some type of DDoS attack in 2012. By comparison, a survey of 704 North American organizations released in April 2012 showed that 35 percent had been targeted by DDoS within the last year. While the financial services sector has been the primary DDoS target in the U.S., telecommunications companies are the No. 1 target in the U.K., according to the Neustar survey, with 53 percent reporting attacks. Half of U.K. e-commerce companies and 43 percent of online retailers surveyed reported attacks. But only 17 percent of the U.K. financial-services organizations say they had been targeted, compared with 44 percent in the North American survey. The North American data is a bit out of date, so the percentage of financial institutions hit by DDoS is now probably even higher. And attacks aimed at U.K. organizations have been nowhere as fierce as those waged against U.S. banks since September 2012. More Attacks on Way Now that al-Qassam has just announced plans for a fourth phase of attacks, we’re all bracing for more strikes against U.S. banks (see DDoS: Attackers Announce Phase 4 ). But the new survey sends a clear message: No organization is safe from DDoS. “As in North America, U.K. companies face serious challenges as they decide on DDoS protection and attempt to mitigate losses,” Neustar writes in its survey study. “While many companies are hoping traditional defenses will suffice, given the frequency of attacks, their growing complexity and the impact when sites go dark, such hopes are badly misplaced.” U.K. organizations could learn quite a bit from the example U.S. banks have set. Experts have noted time and time again that European banks and others are not well-prepped for DDoS. Despite the fact that the attacks waged against U.S. banks have been among the largest the industry has ever seen, the percentage of U.S. organizations that experienced extended outages was much smaller than that of U.K. organizations, the surveys showed. The defenses U.S. banking institutions have put in place have set a new bar. We already knew that, but now Neustar’s survey results support it. According to Neustar, while online outages lasting about 24 hours affected about 37 percent of both North American and U.K. organizations surveyed, outages lasting more than a week affected 22 percent in the U.K. and only 13 percent in North America. Having a site down for more than a week is an embarrassment, and costly. Can you even imagine a major banking institution’s site being down that long? Banks in the U.S. are prepared for DDoS. But what about other organizations? Are non-banks getting ready for DDoS, or do they still see this as only a threat to banking institutions? What you think? Let us know in the comment section below.

Staying Informed About DDoS Threats

Distributed-denial-of-service attacks have plagued U.S. banks since last September. But DDoS attacks pose a persistent, genuine threat to other sectors as well. Any organization with an online presence is at risk. Successful DDoS attacks can take a website offline, damaging brand image and chipping away at consumer trust. But they also can do much more. In some cases, these attacks can be used to mask fraud by distracting security and IT departments while banking accounts or confidential files are simultaneously being taken over. To provide insights on the latest DDoS threats – and effective mitigation strategies – Information Security Media Group has launched a DDoS Resource Center . The resource center, sponsored by online security firms Akamai, Fortinet, Neustar, Radware and VeriSign, includes timely interviews, in-depth features, news stories and blogs that offer insights about emerging botnets and attack techniques from those who are analyzing and battling DDoS on the frontlines. The resource center also offers expert insights on practical steps for minimizing the impact of DDoS attacks. By visiting the resource center, you’ll get the latest information on the different types of DDoS attacks, such as DNS reflection and application layer attacks, as well as the attacks’ possible links to fraud . You’ll learn about DDoS protections and mitigation services , notification and response strategies, and DDoS detection measures. Here’s a sampling of the variety of content our resource center offers: An interview with ex-FBI investigator Shawn Henry , who shares insights about cross-border and cross-industry collaboration that’s taking place behind the scenes to strengthen DDoS and cybersecurity knowledge. An analysis of a new type of DDoS strike that targeted two U.S. banks for what some say could have been a test for more attacks to come. A blog about how the botnet, known as Brobot, that’s been used in DDoS attacks against U.S. banks is being retooled to defeat common mitigation practices. And an interview with former federal banking examiner Amy McHugh about why community banks are prime targets for DDoS strikes being waged as modes of distraction to veil account takeover attempts. The DDoS Resource Center also provides research, white papers and webinars, including a session on new defense strategies for DDoS , which includes insights from Rodney Joffee of DDoS-mitigation provider Neustar and Mike Wyffels, senior vice president and chief technology officer of multibank holding company QCR Holdings Inc.

Staying Informed About DDoS Threats

Tips To Prepare For A DDoS Attack

IT security experts report that distributed denial of service (DDoS) attacks are a growing concern for 2013: this trend is proved by the countless attacks during 2012 and shown from the findings on the latest CSI Computer Crime & Security Survey, which attracts widespread media attention and is one of many online sources that provides valuable information and guidance to information security professionals. How can a business or individual decrease the likelihood of these type of threats? Fortunately, there are methods that can be used in advance to mitigate risk and infections from the amplification of such attacks. Safety First First of all, it is paramount to identify if the network is safe and protected from unauthorized access, malicious content, real-time threats and cyber intrusions. If not, network system managers should consider using traditional security products like a firewall, Intrusion Prevention and Detection Systems (IPDS) and Web application firewall devices to establish a first line of security defense. It is crucial to be responsive and implement the necessary security hardware and software tools ahead of time to defend the perimeter of the network from intrusion and before being the hacker’s target. Business and individuals alike should plan early on and not wait until they are at mercy of the attack to use proper security controls. Malicious attacks, which can be carried out from several compromised systems and from another location (IP address), can enable a rogue attacker to install a series of zombie Trojans to attack or infect (with malware) hosted computers. Whatever reason and motive the intruder has, s/he is able to take over an entire network and initiate a flood or packet attack, all while denying legitimate connections and paralyzing victims’ systems or servers (e.g., Web servers, DNS servers, application servers). The aim is to use up the network bandwidth and bring its operations or services down. Knowing how dangerous such an attack can be, it comes of utmost importance to be familiar with the different kind of DDoS attacks that could affect the network to understand what type of countermeasures should be put to use. Despite the scale and frequency of these attacks, there are ways to be prepared and avoid being vulnerable to this threat that can be so disruptive. Next is a list of tips to prepare and plan, before an attack strikes, which if made a victim of could have devastating effects on one’s business, such as costly downtime and/or lost revenue. Here are six ways to prevent a DDoS attack • Utilize packet filters on the router(s) • Setup a firewall with advanced security • Properly configure webserver with security modules • Implement logging with ACLs and have them in place to filter traffic • Exploit NetFlow for traffic monitoring and tracking down specific attacks • Rely on a third-party cloud DDoS mitigation provider for proprietary filtering technology. This is a great alternative for those that do not want to handle the security themselves and obtain a quick solution that provides on-demand, real-time protection to monitor 24/7 a business or individuals’ on-premises network infrastructure. If you’re looking for reputable provider, I would suggest getting DDoS protection from DOSarrest . Other than the tips listed, it is suggested to always have more bandwidth available, maintain anti-virus software, and deploy IPDS devices or firewalls in front of the servers just in case of a DDoS attack. It is better to spend some time (and money) preparing in advance for this network threat than dealing with a last minute crisis and trying to figure out what needs to be done.

Tips To Prepare For A DDoS Attack

Preparing for Battle: DDoS Attacks On Business

Lately, DDoS attacks have crept back into the headlines, forcing businesses to reacquaint themselves with the concept. DDoS stands for distributed denial-of-service which uses multiple machines to carry out a DoS attack on unsuspecting victims. It is estimated that over 7,000 attacks happen daily with the motives and severity of consequences varying between different attacks but all have the potential to greatly harm a company’s operations. To minimize any possible damage, it is important to prepare a defense against these malicious attacks especially as they are on the rise and could target your business at any moment. How to realize you are in the midst of a DDoS attack At the beginning of a DDoS attack, you may fail to even realize what is occurring. The optimistic side of you wants to believe that your marketing efforts have finally kicked in and created a sudden wave of interested customers to your website. However great that may be, the reality is as the numbers increase and overwhelm your servers, you are more likely to be under attack. When a DDoS attack occurs they are using one of two avenues: a special malware that infects the machines of others in order to carry out the attack from a large number of hosts or utilizing a large number of volunteers to their cause to perform the attack in unison. Regardless of the technique employed, they both use many host computers to access the target’s website and overwhelm their servers which results in long periods of downtime. Why Attackers Target You The reasons behind DDoS attacks can vary depending on the organization performing the attack and who they are attacking. The most common reason behind an attack is extortion where they perform a small attack on your servers first, then contact you demanding a certain amount of money to prevent a larger attack from occurring. The more profitable a company you are, the higher the chance you will be a target for extortion. Also, if your organization is currently in the spotlight for political controversy, there are many “hacktivists,” like the group Anonymous, who carry out DDoS attacks to satisfy their political agenda. Lastly, in sophisticated and large-scale attacks, the hackers could be attempting a security breach in order to obtain confidential information. All of these causes could create a devastating impact upon your company’s image. The Effects of DDoS Attacks 1. Revenue The more heavily you rely on your website as a means for business, the more severe a DDoS attack will affect your company. The average daily revenue loss from attacks for those that depend heavily on the Internet for their business is $2,000,000 or nearly $100,000 per hour. Even if you are a smaller organization with less reliance on the Internet, the average loss is $10,000 per hour when in downtime. These are significant amounts of losses that could be hard to recover from, especially for a small business. 2. Reputation As a DDoS attack is occurring, it becomes nearly impossible for any customer to access your website and results in an unpleasant experience for them. For instance, if you are a banking website, they can’t access their accounts which is very critical and leaves them feeling like their private information is at risk. Even after the attack is over, you will have to spend time and money in public relations efforts to reinstate faith in your service from your customer base. 3. Lawsuits When the attack breaches security and confidential information, a risk for lawsuits from customers and consumer protection groups occurs. Now you are not only looking at revenue loss from the downtime and from a loss of reputation but also, significant legal fees associated with your company failing to protect customer information. If all three occur, the DDoS attack could be enough to send your company into bankruptcy and impending failure. How to Protect Your Company The devastating effects from a DDoS attack is enough to leave you shaking in your boots, however most companies still fail to provide adequate protection against said attacks. As the sophistication of these attacks increase, your company’s firewall and current security measures may not be enough to handle a full-scale attack. In a recent survey, Neustar only found that 3% of the surveyed organizations had an anti-DoS solution. Here are some steps you should take to protect your company in the event of a DDoS attack: Develop a defense strategy immediately so you are prepared to take action when an attack occurs. Identify current security lapses or vulnerabilities within your website. If you have been a victim from an attack, keep information collected about it so you can determine how to properly fight off future attacks Simulate a DDoS attack to ensure your response measures are adequate. Consider purchasing an anti-DoS service from a security provider to narrow the possibility of attack. Combine anti-DoS service with the above steps to provide a comprehensive approach to protection. As DDoS attacks are on the rise, now is the time to prepare your company in the event of attack. Even smaller organizations could become victims, so it is important to be ready to defend your company’s website and servers from hackers. Following the steps for protection can prevent a DDoS attack from causing results that could be extremely difficult to recover from, allowing you to come out victorious in an otherwise disastrous situation.

Iranian Hackers Launching Cyber-Attacks on U.S. Energy Firms: Report

Iranian hackers launched attacks as part of a campaign against the country’s oil and gas industry, according to current and former U.S. government officials. Iranian hackers have amped up a campaign of cyber-attacks against America’s energy industry, according to a report from The Wall Street Journal . Citing current and former U.S. officials speaking under the blanket of anonymity, the Journal reported that Iranian hackers accessed control system software that could have allowed them to manipulate oil or gas pipelines. The attacks raise the stakes in cyber-space between the U.S. and Iran, which has been accused by U.S. officials of being behind a spate of distributed denial-of-service attacks (DDoS) against U.S. banks stretching back to 2012. “This is representative of stepped-up cyber activity by the Iranian regime. The more they do this, the more our concerns grow,” a source told the Journal . “What they have done so far has certainly been noticed, and they should be cautious.” Alireza Miryousefi, Iran’s spokesperson at the United Nations, denied any connection between hackers and the regime in an interview with the Journal . The officials who spoke to The Wall Street Journal did not name any of the energy companies targeted in the attacks. But two former officials said oil and gas companies located along the Canadian border were among those hit. Word of the attacks comes a week after Charles Edwards, deputy inspector general at the U.S. Department of Homeland Security, told members of a Senate subcommittee that industrial control systems were increasingly coming under attack in cyber-space in ways that could potentially cause “large-scale power outages or man-made environmental disasters.” Securing these systems is complicated, as many are more interconnected with the Internet than people realize, explained Tom Cross, director of security research at network security vendor Lancope. “It is also difficult to fix security flaws with these systems because they aren’t designed to be patched and restarted frequently,” he said. “It is extremely important,” he continued, “that operators of industrial control networks monitor those networks with systems that can identify anomalous activity that might be associated with an attack. Because of the relatively homogenous nature of network activity on many control systems networks, anomaly detection can be can be a powerful tool in an environment where other kinds of security approaches fall flat.” Much of the talk about improving the security of critical infrastructure companies has focused on information sharing between the government and private sector. Improving communication between government and business figured prominently in the executive order on cyber-security that President Barack Obama issued in February. However, many officials and security experts have said that the order does not undo the need for legislation. “The increases in cyber-assaults on our energy systems from Iranian-backed hackers are another signal to the government and the industry that measures must be taken to fortify the security of our critical infrastructure,” said Lila Kee, chief product and marketing officer at GlobalSign and a North American Energy Standards Board (NAESB) board member. “However, there is a fine line between cyber-security regulation and voluntary standards,” she said. “Regulations cannot be so rigid so as to prevent protection from today’s evolving advanced persistent threats, and voluntary standards cannot be so loose so as to provide no purpose. In today’s modern world of malware, solutions must be fluid and scalable to battle aggressive cyber-attacks.” Source: http://www.eweek.com/security/iranian-hackers-launching-cyber-attacks-on-us-energy-firms-report/
