DDoS attack that disrupted internet was largest of its kind in history, experts say

Dyn, the victim of last week’s denial of service attack, said it was orchestrated using a weapon called the Mirai botnet as the ‘primary source of malicious attack’ The cyber-attack that brought down much of America’s internet last week was caused by a new weapon called the Mirai botnet and was likely the largest of its kind in history, experts said. The victim was the servers of Dyn, a company that controls much of the internet’s domain name system (DNS) infrastructure. It was hit on 21 October and remained under sustained assault for most of the day, bringing down sites including Twitter, the Guardian, Netflix, Reddit, CNN and many others in Europe and the US. The cause of the outage was a distributed denial of service (DDoS) attack, in which a network of computers infected with special malware, known as a “botnet”, are coordinated into bombarding a server with traffic until it collapses under the strain. What makes it interesting is that the attack was orchestrated using a weapon called the Mirai botnet. According to a blogpost by Dyn published on Wednesday, Mirai was the “primary source of malicious attack traffic”. Unlike other botnets, which are typically made up of computers, the Mirai botnet is largely made up of so-called “internet of things” (IoT) devices such as digital cameras and DVR players. Because it has so many internet-connected devices to choose from, attacks from Mirai are much larger than what most DDoS attacks could previously achieve. Dyn estimated that the attack had involved “100,000 malicious endpoints”, and the company, which is still investigating the attack, said there had been reports of an extraordinary attack strength of 1.2Tbps. To put that into perspective, if those reports are true, that would make the 21 October attack roughly twice as powerful as any similar attack on record. David Fidler, adjunct senior fellow for cybersecurity at the Council on Foreign Relations, said he couldn’t recall a DDoS attack even half as big as the one that hit Dyn. Mirai was also used in an attack on the information security blog Krebs on Security, run by the former Washington Post journalist Brian Krebs, in September. That one topped out at 665 Gbps. “We have a serious problem with the cyber insecurity of IoT devices and no real strategy to combat it,” Fidler said. “The IoT insecurity problem was exploited on this significant scale by a non-state group, according to initial reports from government agencies and other experts about who or what was responsible. “Imagine what a well-resourced state actor could do with insecure IOT devices,” he added. According to Joe Weiss, the managing partner at the cybersecurity firm Applied Control Solutions and the author of Protecting Industrial Control Systems from Electronic Threats, it is hard to know what Mirai could become. “A lot of these cyber-attacks start out as one particular type of attack and then they morph into something new or different,” he said. “A lot of this is modular software. “I can’t speak for anyone else,” Weiss continued. “[But] I don’t know that we really understand what the endgame is.” Source: https://www.theguardian.com/technology/2016/oct/26/ddos-attack-dyn-mirai-botnet

Chinese Firm Defends Webcam Security After DDoS Attacks

Hangzhou Xiongmai Technology says devices sold in the US before April 2015 will be recalled after attack on Dyn servers. China’s Hangzhou Xiongmai Technology, which has issued a recall for thousands of webcams sold in the US that were used in a massive distributed denial of service (DDoS) attack on the servers of US-based internet company Dyn, said the hacks occurred because customers didn’t change the default password, according to the AP. The attack, which in part came through devices with Xiongmai components, briefly cut access to many sites including Twitter, Netflix, Amazon, and Spotify. Xiongmai’s Liu Yuexin told AP the company did its best to secure the devices. The company, he added, came to know of the weakness in its webcams and digital recorders in April 2015 and had patched the flaws. Vulnerabilities in devices by Xiongmai and video surveillance maker Dahua first came to light after an attack on the website of cybersecurity writer Brian Krebs and has highlighted concerns of security risks from interconnected consumer gadgets.

Chinese firm recalls camera products linked to massive DDOS attack

Hangzhou Xiongmai Technology is recalling earlier models of four kinds of cameras due to a security vulnerability A Chinese electronics component maker is recalling 4.3 million internet-connected camera products from the U.S. market amid claims they may have played a role in Friday’s massive internet disruption. On Monday, Hangzhou Xiongmai Technology said it was recalling earlier models of four kinds of cameras due to a security vulnerability that can make them easy to hack. “The main  security  problem is that users aren’t changing the device’s default passwords,” Xiongmai said in a Chinese-language statement posted online. According to  security  firm Flashpoint, malware known as Mirai has been exploiting the products from Xiongmai to launch massive distributed denial-of-service attacks, including Friday’s, which slowed access to many popular sites, including Netflix, PayPal, and Twitter. Companies observing Friday’s disruption said botnets powered by the Mirai malware were at least partly responsible for the attack. Xiongmai, a maker of camera modules and DVR boards, has acknowledged that its products have been a target for hackers, but it said it patched the problem with the default passwords back in April 2015. For older products, the company has come up with a firmware update to fix the flaw. To prevent the security risks, the company has still decided to recall earlier models. However, Xiongmai has also dismissed news reports that its products were largely behind Friday’s DDOS attack as untrue and is threatening legal action against those who damage its reputation. “Security vulnerabilities are a common problem for mankind,” the  company  said. “All industry leaders will experience them.” Experts have said the Mirai malware is probably targeting products from several vendors, in addition to Xiongmai. The malicious coding is built to try a list of more than 60 combinations of user names and passwords when infecting  devices . So far, the Mirai malware has gone on to infect at least 500,000 devices, according to internet backbone provider Level 3 Communications.

Anonymous hacker charged with #opJustina DDoS attacks on hospital

The Anonymous-affiliated hacker who admitted to cyberattacks on two hospitals in the #opJustinaoperation and fled the country while being investigated was indicted last week. Martin Gottesfeld, 32, a biotechnology information technology professional from Somerville, Massachusetts, is being charged with conspiracy to launch cyberattacks against two local hospitals: Boston Children’s Hospital (BCH) and the Wayside Youth and Family Support Network, a mental health facility. Those two hospitals were at the center of a case that attracted masses of media attention: that of Justina Pelletier, the then-15-year-old who was caught in a 16-month custody battle as her parents tried to have her treated for mitochondrial disease at one hospital, while Boston Children’s Hospital treated her in a psychiatric unit as a ward of the state. Gottesfeld’s indictment, handed down on Wednesday, also charges him with intentional damage to a protected computer. Both are felony hacking charges. Gottesfeld admitted to the attacks last month, explaining how he did it and why in an editorial published by the Huffington Post. I had heard many, too many, such horror stories of institutionalized children who were killed or took their own lives in the so-called “troubled teen industry”. I never imagined a renowned hospital would be capable of such brutality and no amount of other good work could justify torturing Justina. The distributed denial of service (DDoS) attack against BCH was planned for maximum financial damage, Gottesfeld said: he knew that the hospital was planning a big fundraising drive and that most donors gave online. In his editorial, he went on to scoff at BCH for making it easy for him to attack it, since the hospital kept its donation page on the same public network as the rest of its systems: Rookie mistake. To take it down, I’d have to knock the whole hospital off the internet. He also claimed that no patients would be harmed: There’s no such thing as an outage-proof network, so hospitals have to be able to function without the internet. It’s required by federal law, and for accreditation. The only effects would be financial and on BCH’s reputation. That’s not how the hospital, or the prosecution, sees it. The indictment states that BCH had to shut down its access to the internet and email servers to protect patient medical records. That meant that physicians outside the hospital couldn’t get at patients’ records. Nor could patients communicate with their doctors. BCH claims that responding to, and mitigating, the damage of the attack cost $300,000, while the disruption in fundraising meant another $300,000 hit, for a total loss of $600,000. Gottesfeld claims that the attack against BCH was a justifiable reaction to the actions of the hospital, which was described as  a “parentectomy”. Gottesfeld’s defence, to blame the hospital for the attack, is all too commonly heard. The blame-the-victim reasoning is often voiced by other cyberattackers, be it from people who guess at weak passwords and use them to waltz into accounts without authorization, or those who launch crippling attacks such as those that Gottesfeld admits to. But just because it’s easy to do doesn’t make those or other cybercrimes OK. They’re illegal, and they can result in jail time, fines or both. Each of the charges Gottesfeld’s facing carry a maximum sentence of five years in jail, along with fines. Gottesfeld has been detained in Rhode Island since he and his wife were plucked off their boat near the coast of Cuba and arrested in Florida. When the indictment was handed down last Wednesday, Gottesfeld was reportedly on day 16 of a hunger strike over the appointment of the office of Carmen Ortiz as his prosecutor. Ortiz was the prosecutor in the cases against both Aaron Swartz and Jonathan James, who both later took their own lives. She has faced sharp criticism over her approach to those cases. In spite of his admission to the DDoS attacks, Gottesfeld is likely to plead not guilty at his arraignment this week before US Magistrate Judge Marianne B. Bowler, his wife told the Washington Times.

Media vulnerable to Election Night cyber attack

A hack on the AP and its results tally could have chaos-inducing consequences. Despite spending hundreds of millions of dollars on security upgrades, U.S. media organizations have failed to properly protect their newsrooms from cyberattacks on their websites, communications systems and even editing platforms — opening themselves up to the possibility of a chaos-creating hack around Election Day. In just the past month, BuzzFeed has been vandalized, and both Newsweek and a leading cybersecurity blog were knocked offline after publishing articles that hackers apparently didn’t appreciate. Federal law enforcement is investigating multiple attacks on news organizations, and journalists moderating the presidential debates say they’ve even gotten briefings from the FBI on proper cyber hygiene, prompting them to go back to paper and pens for prep work. “We do a lot of printing out,” said Michele Remillard, an executive producer at C-SPAN, the network home to the backup moderator for all the debates. Journalists are seen as especially vulnerable soft targets for hackers. Their computers contain the kinds of notes, story ideas and high-powered contact lists coveted by foreign intelligence services. They also work in an environment that makes them ripe for attack, thanks to professional demands like the need for a constant online presence and inboxes that pop with emails from sources whom they don’t always know and which frequently contain the kinds of suspicious links and attachments that can expose their wider newsroom networks. Senior U.S. officials, current and former lawmakers and cybersecurity pros told POLITICO the threat against the media is real — and they fret the consequences. Specifically, the security community is worried The Associated Press’ army of reporters could get hacked and the wire service — the newsroom that produces the results data on which the entire media world relies — inadvertently starts releasing manipulated election tallies or that cybercriminals penetrate CNN’s internal networks and change Wolf Blitzer’s teleprompter. “It’s the art of possible is what really scares me,” said Tony Cole, chief technology officer of FireEye, a Silicon Valley-based cybersecurity firm that works with some of the country’s major television and newspaper companies. “Everything is hackable.” “No site is safe,” added Tucker Carlson, editor-in-chief of The Daily Caller. “If the federal government can be hacked, and the intelligence agencies have been hacked, as they’ve been then, can any news site say we have better cybersecurity than the FBI or Google?” The media have long been a spy’s best friend. Intelligence community sources say that foreign and U.S. agents use local newspapers to look for clues about their targets, and that strategy has only grown more sophisticated in an all-online era in which foreign intelligence is reportedly known to hover over a media company’s servers searching for any kind of heads-up on relevant stories inching closer to publication. Reporters on the campaign trail and back in their home bureaus said in interviews that they’ve become increasingly aware of their status as potential hacking victims. The spate of recent attacks — involving their sites and their competitors’ — are more than ample warning of what’s possible. Several journalists said they now use email and other communication with the expectation they’re being watched, and under the assumption that their messages can and will be hacked and shared publicly with the wider world. “We’re a bigger target than the 7-Eleven down the street,” said Mark Leibovich, chief national correspondent for The New York Times Magazine. “Presumably, we have really good, smart IT people who know what they’re doing, who are taking all kinds of precautions, who are acutely in tune with what the risks are and what the threats are.” There is perhaps no greater target in election journalism than the AP, the venerable wire service that will have more than 5,000 reporters, editors and researchers working across the country, tabulating results, calling races and feeding a much wider network of subscribers. Often other news outlets refer to the AP before making calls on races, and AP projections on the East Coast can have effects on West Coast voting, which closes hours later thanks to the time differences. Multiple sources in media, government and the security industry fretted about the effect if the AP were to get hit, and what that would do to their ability to get the news out. The AP will deploy reporters across the country to send up vote tallies, usually by phone, the  wire service  explained to The Washington Post in May. It also has multiple checks and balances in place to monitor for errors. But as with many other news organizations contacted by POLITICO, AP spokesman Paul Colford said the wire service’s policy is to refrain from making public comments about its security measures. “Given the extraordinary interest in the presidential election and thousands of other state and local contests, we would add that AP has been working diligently to ensure that vote counts will be gathered, vetted and delivered to our many customers on Nov. 8,” he said. Federal and state officials stress that even a successful hack on a major news outlet around Election Day would not affect the final results, which typically take weeks to certify. The vote tallies, after all, will be available on official sites and in many instances on special social media feeds. And if a news site did get defaced with incorrect information, the results would be more like a modern-day version of the famous ‘Dewey Defeats Truman’ headline that President Harry Truman triumphantly held aloft the day after his 1948 reelection. Still, there is a widespread recognition — from the White House down to the local precinct level — that a hack on the media could be damaging given the role it plays in getting election news out to satisfy the country’s insatiable information appetite. Misinformation circulated in the early hours of Nov. 8 about the race’s trajectory, for example, could factor into a voter’s decision to even show up during the election’s final hours, especially in Western states. There’s also concern that false media reports spread via a hacked news account could be a potential spark for violence in an already exceptionally charged atmosphere. On the flip side, there’s a recognition that the media can help build public confidence in the final results, especially following a campaign that’s been engulfed in its closing weeks by Russian-sponsored hacking of the Democratic National Committee, the hacking of Hillary Clinton’s campaign chairman’s personal emails, and Donald Trump’s unfounded charges of vote rigging. “To the degree that foreign hackers could prevent the dissemination of good information around the election, that can be a problem,” said Rep. Adam Schiff, the top Democrat on the House Intelligence Committee. The California congressman said he frets that media outlets, like many other industries, face “massive costs” in protecting themselves against cyberattacks with “no end in sight” to the potential risks. Schiff added that he is especially concerned about smaller news organizations without major IT budgets or the backing of larger parent companies. “They’re much more vulnerable,” he said. Cybersecurity experts say media spending to protect news organizations against cyberattack has grown substantially in the past three years, especially in the wake of North Korea’s attack on Sony Pictures in late 2014. The price tag for vulnerability audits and other techniques varies by the size of the newsroom and the surface area for potential attacks, but multiple sources said quarterly audits can easily cost $50,000 or more. Cyber experts and media officials from newsrooms across the country said they’re prepped to deal with a range of threats to their sites, including the kinds of malware that can infect a computer network and give hackers an entry point to manipulate a home site. They’re also building backup capacity in the event of a DDoS attack, or distributed denial of service, that tries to overwhelm a website or server with fake traffic. News sites, they note, are already prepping for monster traffic around the election, which can surge as much as 30 times compared with other big events this cycle, such as a debate or primary. At the staffing level, newsrooms have also been pushing for better cyber habits by hosting training seminars, requiring employees to take must-pass exams and requiring double-authentication before granting access to a newsroom’s internal filing system and social media accounts. But cyber experts warn that all the preparatory work in the world can matter little for a news organization if it’s facing an attack from a more sophisticated actor. “If all of a sudden your adversary becomes a nation-state, like Sony or the DNC with Russia, you see those kind of procedures aren’t worth a darn,” said Robert Anderson, a former senior FBI cyber official and a managing director at the Navigant consulting firm. The press has indeed been a familiar target for hackers. In 2013, hackers hit the AP’s Twitter account and posted a false report about a bombing at the White House, sending the stock market into a five-minute spiral. In more recent incidents, a USA Today columnist wrote an article in February admitting he was hacked midair while using his commercial flight’s WiFi, and the New York Times reported in August that its Moscow bureau was targeted by what were believed to be Russian hackers. Newsweek blamed hackers for a DDoS attack that took down its site last month soon after it published an article about Trump’s company allegedly violating the U.S. embargo against Cuba through secret business dealings in the 1990s. And BuzzFeed had several articles on its site altered earlier this month after it ran a story identifying a person allegedly involved in the hacking of tech CEOs and celebrities. “I’m sure that lots of newsrooms are having this conversation right now, particularly as we get closer to the election and people have a lot more to lose when things don’t go their way,” said Brian Krebs, the cybersecurity blogger and former Washington Post reporter whose site went down last month after a major DDoS attack that he says was spawned by his reporting about the arrest of two Israeli hackers. With the threat of hackings against the media reaching such a heightened pace, many election observers urged both reporters and the reading public to take a deep breath as the results start coming in. “If Twitter is reporting that Jill Stein wins South Carolina, that should probably give you pause,” said David Becker, executive director of the Center for Election Innovation and Research.
