Taiwan high-tech industry hardest hit by DDoS attacks in last 30 days

TAIPEI (Taiwan News)—Most denial-of-service (DDoS) attacks launched by hackers from Feb. 15 to March 14, 2017 in Taiwan targeted the high-tech industry, according to statistics compiled by leading global content delivery network provider Akamai Technologies. Industries in Taiwan that were most severely attacked by hackers were the high technology industry (61.8 percent), manufacturing industry (17.6 percent) and the financial services industry (7 percent), according to statistics compiled by Akamai’s intelligent platform that delivers 30 percent of the global Internet traffic. Industries in Taiwan under DDoS attacks from February 15 to March 14, 2017. (Taiwan News) The majority of the hacks were launched from IP addresses in Taiwan, followed by Alabama in the U.S., and Brazil. “It is often a misconception that most attacks are launched from abroad,” said Akamai’s Security Business Unit director Amol Mathur. “Attacks are coming both domestic and outside.” The premium CDN provider works customizes solutions for clients from different industries in Taiwan, including hospitality, banking, travel and airline services. Taiwan’s financial institutes are still recovering from a cybersecurity scare last month, in which 15 banks received threats from an anonymous hacker group to shell out 10 Bitcoins each (equivalent to US$10,466), or brace themselves for DDoS attacks that would compromise their server systems. DDoS attacks launched by hackers often compromise institute’s servers data processing capacity by delivering a sudden deluge of data that overtakes bandwidth resources, for instance if the company server bandwidth only allows 10 Gigabyte per second (Gbps) of capacity it can be paralyzed by a 100 Gbps attack. Hackers might use DDoS as a distraction to conceal other malign operations, such as stealing personal information or credential theft, added Mathur. Industries affected by hacker attacks vary monthly, depending on whether there is a major geopolitical event, said Mathur. For instance global hacker group Anonymous took down the London Stock Exchange system for two hours as part of its campaign against global central banks in June 2016. Mathur advised banks should not heed hacker demands to pay ransom. “In real life you would not pay ransom, so why would you pay hackers,” he said. The cybersecurity expert noted a rise in DDoS attacks globally during the fourth quarter of 2016, and pointed out DDoS attacks data size was increasing exponentially every quarter. Globally, attacks over 100 Gbps jumped 140 percent year-on-year during 4Q16, with the largest-size attack recorded reaching 517 Gbps, according to the Akamai “Fourth quarter 2016 State of the Internet/Security Report.” Mathur noted the cause of increased DDoS attacks was partly due to easy access for people to rent bots online, for as cheap as US$10 by going to a site and simply keying in the website address. Hackers can generate a monthly income of US$180,000 to US$200,000 from bot rentals. It remains extremely difficult for law enforcement agencies from a single country to track down hackers that spread the attacks launched by rented bots around the globe, and hide behind the protection of anonymity offered by the dark web. Additionally, the preferred Bitcoin currency used for business transactions by hackers is hard to trace to an IP address, explained Mathur. Introduction of mobile devices, mobile payment, IP surveillance cameras and emerging Internet of Things (IoT) trends introduce new cybersecurity vulnerabilities as hackers can utilize attacks through large number of connected devices. The Mirai bot for instance exposed vulnerabilities in the default user administrator name and passwords used by thousands of connected IP surveillance cameras and their DVR worldwide, said Mathur. He urged the IoT industry to form a joint standard, and for countries to start implementing regulations that set cybersecurity standards for connected devices. Hackers are also finding ways to target vulnerabilities in smartphone application programming interface (API) to obtain credentials, and data from mobile transactions. Apple Pay and some other mobile payment technologies periodically publish white papers announcing how it is securing data, but are mostly for tech savvy readers, said Mathur. One way consumers can safeguard credit card transactions is to check if the online shopping sites or App they use have The Payment Card Industry Data Security Standard (PCI DSS), noted Mathur. The proprietary information security standard launched nearly a decade ago by major credit card companies Visa, MasterCard, American Express, JCB and others follows a stringent standard and heavily fines companies that do not follow its compliance.

DDoS Attacks; Can You Find Who Dunnit?

Kaspersky Lab and B2B International recently polled 4,000 businesses among 25 countries that had been hit by a distributed denial of service (DDoS) attack; 40% of respondents said they believed that a rival business had launched the attack. Only 20% of DDoS victims blamed foreign governments and secret service organizations, and another 20% suspect disgruntled former employees. These are interesting statistics, given that it is extremely difficult to determine who launched a DDoS attack. Has law enforcement found any trends to support this belief that many DDoS attacks are caused by industrial sabotage? Maybe, maybe not. When it comes to hacking—especially DDoS hacks—law enforcers seldom find the perpetrators, because it is extremely difficult for anyone to trace the origins of DDoS attacks. The source is typically 1) a legitimate third-party server, running a service which has been leveraged by an attacker as part of a reflection/amplification attack, or 2) a direct flood attack from a single device, or 3) a botnet of many devices in which the IP source addresses are easily spoofed to ones that cannot be associated with the attacker. Motivations and Means Hacker motivations vary; some are political, others are financial. Certainly, if a business wanted to inflict financial or reputational harm upon a competitor, a DDoS attack would do the trick. After all, it is easy and relatively inexpensive for anyone to rent a botnet or DDoS-for-hire service to carry out a DDoS attack. Yes, it’s possible, but do victims have any evidence to back up their suspicions, or are they just paranoid about a rival business? Likewise, the threat of a disgruntled, malicious insider or former employee is a reasonable concern. But again, it is hard to trace the breadcrumbs. Speculating about “who dunnit” is usually pointless; there’s little hope of hunting down the perpetrator(s), and it costs time and money to conduct an investigation. Even if the perps are brought to justice, they’ve already damaged your business. The moral of the story is that it’s useless to close the proverbial stable door after the horse has left; the best approach is to prevent an attack by having DDoS protection in place.

IoT DDoS Reaches Critical Mass

In the wake of the Mirai botnet activity that dominated the end of last year, the “DDoS of Things (DoT)”, where bad actors use IoT devices to build botnets which fuel colossal, volumetric DDoS attacks, has become a growing phenomenon. According to A10 Networks, the DoT is reaching critical mass—recent attacks have leveraged hundreds of thousands of IoT devices to attack everything from large service providers and enterprises to gaming services, media and entertainment companies. In its research, it uncovered that there are roughly 3,700 DDoS attacks per day, and the cost to an organization can range anywhere from $14,000 to $2.35 million per incident. In all, almost three quarters of all global brands, organizations and companies (73%) have been victims of a DDoS attack. And, once a business is attacked, there’s an 82% chance they’ll be attacked again: A full 45% were attacked six or more times. There were 67 countries targeted by DDoS attacks in Q3 2016 alone, with the top three being China (72.6%), the US (12.8%) and South Korea (6.3%). A10 found that 75% of today’s DDoS attacks target multiple vectors, with a 60/40 percentage split of DDoS attacks that target an organization’s application and network layers, respectively. Meanwhile, DDoS-for-hire services are empowering low-level hackers with highly damaging network-layer bursts of 30 minutes or less. This relentless attack strategy systemically hurts corporations as colossal DDoS attacks have become the norm too; 300 Gbps used to be considered massive, but today, attacks often push past 1 Tbps thanks to the more than 200,000 infected IoT devices that have been used to build global botnets for hire. No industry is immune: While 57% of global DDoS attacks target gaming companies, any business that performs online services is a target. Software and technology were targeted 26% of the time; financial services 5%; media and entertainment, 4%; internet and telecom, 4%; and education, 1%.

185,000+ vulnerable Wi-Fi cameras just waiting to be hijacked

A generic wireless camera manufactured by a Chinese company and sold around the world under different names and brands can be easily hijacked and/or roped into a botnet. The flaw that allows this to happen is found in a custom version of GoAhead, a lightweight embedded web server that has been fitted into the devices. This and other vulnerabilities have been found by security researcher Pierre Kim, who tested one of the branded cameras – … More ?

Businesses blame rivals for DDoS attacks

Industrial sabotage is considered to be the most likely reason behind a distributed denial of service attack, a study has revealed More than 40% of businesses hit by a distributed denial of service (DDoS) attack worldwide believe their competitors were behind it, research by Kaspersky Lab and B2B International has revealed. Rival firms are considered more likely culprits than cyber criminals, which were cited as suspects by just 38% of DDoS victims on average. Industrial sabotage is considered to be the most likely reason behind a DDoS attack, coming out higher than political conspiracy and personal vendettas against a business. Typically, DDoS attacks target web servers and aim to make websites unavailable to users. Although no data is stolen, the interruption to the service can be costly in terms of lost business damage to reputation. For example, a massive DDoS attack on Luxembourg’s government servers that started on 27 February 2017 reportedly lasted more than 24 hours, and affected more than a hundred websites. The joint Kaspersky Lab, B2B International study, which polled 4,000 businesses in 25 countries, found that only 20% of DDoS victims overall blamed foreign governments and secret service organisations, with the same proportion suspecting disgruntled former employees. Companies in Asia Pacific are the most suspicious of competitors, with 56% blaming their rivals for DDoS attacks and 28% blaming foreign governments. Personal grudges also carry more suspicion in the region too, with 33% blaming former staff. In Western Europe, only 37% of companies suspect foul play by their competitors, with 17% blaming foreign governments. Looking at attitudes by business size, businesses at the smaller end of the scale are more likely to suspect their rivals of staging an experienced DDoS attack. The study found that 48% of small and medium business representatives believe this to be the case compared with only 36% of enterprises. In contrast, respondents from big companies put more blame on former employees and foreign governments. “DDoS attacks have been a threat for many years, and are one of the most popular weapons in a cyber criminals’ arsenal,” said Russ Madley, head of B2B at Kaspersky Lab UK. “The problem we face is that DDoS attacks can be set up cheaply and easily, from almost anyone, whether that be a competitor, a dismissed employee, socio-political protesters or just a lone wolf with a grudge. “It’s therefore imperative that businesses find an effective way to safeguard themselves from such attacks,” he said. Significant advances in DDoS attacks There were significant advances in DDoS attacks in the last quarter of 2016, according to Kaspersky, with the longest DDoS attack in lasting 292 hours or 12.2 days, which set a record for 2016 and was significantly longer than the previous quarter’s maximum of 184 hours. The last quarter of 2016 also saw the first massive DDoS attacks using the Mirai IoT (internet of things) botnet technology, including attacks on Dyn’s Domain Name System (DNS) infrastructure and on Deutsche Telekom, which knocked 900K Germans offline in November. There were also similar attacks on internet service providers (ISPs) in Ireland, the UK and Liberia, all using IoT devices controlled by Mirai technology and partly targeting home routers in an attempt to create new botnets. Stakeholders recognise lack of security in IoT devices According to Kaspersky, stakeholders worldwide, in particular in the US and EU, recognise the lack of security inherent in the functional design of IoT devices and the need to set up a common IoT security ecosystem. Kaspersky expects to see the emergence of further Mirai botnet modifications and a general increase in IoT botnet activity in 2017. Researchers at Kaspersky Lab also believe that the DDoS attacks seen so far are just a starting point initiated by various actors to draw up IoT devices into the actors’ own botnets, test drive Mirai technology and develop attack vectors. First, they demonstrate once again that financial services like the bitcoin trading and blockchain platforms CoinSecure of India and BTC-e of Bulgaria, or William Hill, one of Britain’s biggest betting sites, which took days to come back to full service, were at the highest risk in the fourth quarter and are likely to remain so throughout 2017. Second, cyber criminals have learnt to manage and launch very sophisticated, carefully planned, and constantly changing multi-vector DDoS attacks adapted to the mitigation policy and capacity of the attacked organisation. Kaspersky Lab’s analysis shows that the cybercriminals in several cases tracked in 2016 started with a combination of various attack vectors gradually checking out a bank’s network and web services to find a point of service failure. Once DDoS mitigation and other countermeasures were initiated, researchers said the attack vectors changed over a period of several days. DDoS enters its next stage of evolution Overall, they said these attacks show that the DDoS landscape entered the next stage of its evolution in 2016 with new technology, massive attack power, as well as highly skilled and professional cyber criminals. However, the Kaspersky researchers note that unfortunately, this tendency has not yet found its way into the cyber security policies of many organisations that are still not ready or are unclear about the necessary investments in DDoS protection services.

Blame the US, not China, for the recent surge in massive cyberattacks

The internet’s new scourge is hugely damaging global attacks that harness armies of routers, cameras, and other connected gadgets—the so-called Internet of Things (IoT)—to direct floods of traffic that can take down swaths of the network. The blame so far has largely fallen on the Chinese manufacturers who churn out devices with shoddy security on the cheap. But all those devices have to be plugged in somewhere for them to used maliciously. And American consumers are increasingly the ones plugging them in. Nearly a quarter of the internet addresses behind these distributed denial-of-service, or DDoS, attacks are located in the United States, newresearch from network services firm Akamai has found. Some 180,000 US IP addresses took part in DDoS attacks in the last quarter of 2016, it found—more than four times as many as addresses originating in China. Akamai’s findings are particularly notable because the armies of hacked devices that carry out DDoS attacks—such as those controlled by the Mirai malware—don’t bother covering their tracks. That means the IP addresses are far more likely to genuinely correspond to a location within a certain country, the report’s authors write. The findings also end an era of Chinese dominance in DDoS attacks. Over the previous year, China has accounted for the highest proportion of IP addresses taking part in such attacks globally. Now the US is the clear leader, accounting for 24% of such addresses. The UK and Germany are a distant second and third. (To be clear, though, wherever the attacking devices’ IP addresses are, the person controlling them could be located anywhere.) The huge number of devices taking part in DDoS attacks in the US means regulation there, and in Europe, could stem the flood of damaging traffic. Of course, IoT regulation is a thorny issue—essentially, no US federal agency really wants to take the problem on—and there remain technical questions over how to actually go about blocking the attacks. Still, it’s a lot clearer now that simply pointing the finger at China isn’t enough. Source: https://qz.com/912419/akamai-akam-report-a-quarter-of-ddos-ip-addresses-are-now-from-the-us/

University suffers DDoS attack after it’s schooled by own IoT devices

Infected vending machines and light bulbs teach establishment a lesson. A PLACE WHERE late stage teenagers go to drink and make arses of themselves has fallen victim to a denial of service (DDoS) attack of, essentially, it’s own making. Yeah, we are talking about a university. We do not know what university it is, but Verizon’s breach report for 2016 tells us that the mysterious educational establishment, probably in the US, was taken to its knees by a DDoS attack that was brought about by its own bloody Internet of Things (IoT) devices. It’s kinda like that Mirai thing, but on a much smaller, and more personally embarrassingly scale. We like to imagine that a connected toaster and a connected fridge had a fallout and that everything when bits up. According to Bleeping Computer, which has had a cheeky look at the Verizon report, it was a bit more pedestrian than that. “The DDoS attack was caused by an unnamed IoT malware strain that connected to the university’s smart devices, changed their default password, and then launched brute-force attacks to guess the admin credentials of nearby devices,” Verizon says as it explained that something fishy went down. “Hacked devices would start an abnormally high level of DNS lookups that flooded the university’s DNS server, which in turn resulted in the server dropping many DNS requests, including legitimate student traffic. The university’s IT team said that many of these rogue DNS requests were related to seafood-related domains.” The university has placed all IoT devices, such as light bulbs and vending machines, on its separate subnet, or perhaps in a bin. The security industry reckons that this is a signal of the kind of unprotected troubles to come. Naturally. “On the surface this appears to be more of a prank than a sophisticated denial of service attack. However, proving that largescale IoT takeovers are possible should be a wakeup call to those who manage networks rife with unsecure IoT devices,” said Stephen Gates, chief research intelligence analyst at NSFOCUS by way of introduction. “Municipal, Industrial, Commercial, and now Educational infrastructures are becoming more and more vulnerable, because organisations often carelessly deploy IoT without understanding the ramifications of weak IoT security. “In this case the damage appears to be limited, and only inconvenienced users on a campus network. Do the same to a transportation system, a chemical plant, a hospital complex, an E911 system, or an ISP, and the damage could be much, much greater.” Source: http://www.theinquirer.net/inquirer/news/3004579/university-suffers-ddos-attack-after-its-schooled-by-own-iot-devices#

Five Taiwan brokerages report cyber attack threats, regulator says

Taiwan is investigating an unprecedented case of threats made to five brokerages by an alleged cyber-group seeking payment to avert an attack that could crash their websites, an investigator and the securities regulator said on Monday. Rick Wang, an official with Taiwan’s Financial Supervisory Commission (FSC), said each brokerage had received an email setting a deadline for the transfer of funds to avoid a distributed denial of service (DDoS) attack. Such attacks, among the most common kind on the internet, overload a website until it is forced to inhibit access or go offline. They have become common tools for cyber criminals trying to cripple businesses and organizations with significant online activities. “We have never seen this on such a scale – five companies hit at one time with the same threat,” said Wang, adding that the regulator usually sees single instances of cyber-crime. FireEye, a cybersecurity consultancy, said the attacks were similar to a wave of threatened denial of service attacks by a previously unidentified group that first appeared in Europe last month. The Taiwan attacks do not pose a threat to the island’s broader trading and financial system, Wang said, but he added that the regulator had asked all securities firms to step up defensive measures. One threat recipient, Masterlink Securities Corp, said its website had come under attack, but it had recovered and operations were normal. “The emails were sent under the name of the ‘Armada Collective’,” said Chiu Shao-chou, an official of the internet cybercrime division of Taiwan’s Criminal Investigation Bureau, the government’s top investigation body. The Armada Collective, a hacking extortion group, has been linked to financial blackmail heists elsewhere. But Chiu said the group has been put under watch and Taiwan investigators were still looking into the original source of the emails. The email demanded payment in web-based digital currency bitcoin equivalent to about T$300,000 ($9,731.41), Taiwan media said. None of the securities companies made any payments, Chiu said. Another brokerage firm, Capital Securities Corp, was hit on Monday by a DDoS attack lasting 20 minutes before its system recovered, the regulator said, but it did not link the latest case to the threatening emails. (This version of the story corrects sixth paragraph to show the attacks were similar to, not necessarily part of, a wave of attacks in Europe last month) Source: http://www.reuters.com/article/us-taiwan-cyber-idUSKBN15L128
