This isn’t your grandma’s DDoS Today’s distributed denial of service attacks are different than the kinds that we saw at the dawn of the millennium when the threat emerged. They’re becoming more nuanced, and subtle – and they could result in a lot more than a downed web server.…

Inside the World of the Dark DDoS
The international activist hacker group Anonymous Legion is claiming responsibility for an attack on the Minnesota Judicial Branch’s website that rendered it unusable for most of Wednesday. State officials became aware of the “distributed denial-of-service” (DDoS) attack about 8 a.m. Wednesday, around the same time Anonymous Legion e-mailed the Star Tribune. “Servers have also been penetrated and data has been secured, contrary to what they will tell you,” said Anonymous Legion’s e-mail. “This will occur frequently.” The group said the act was executed “collectively, through a global attack.” It is known for DDOS attacks on government websites, among others. The attack is similar to ones that interrupted the site last December. Last year’s attacks were traced to Asia and Canada. The state did not say Wednesday whether the attacks may be linked. “We are in the process of communicating with the FBI Cyber Task Force about this incident,” Beau Berentson, a spokesman for the state court administration office, said in a written statement. The website (www.mncourts.gov), visited by thousands every day looking to access court resources and information, was taken offline as the attack was investigated. Access to the site was restored around 5:15 p.m. “We have no evidence that any secure data has been inappropriately accessed,” Berentson said. Other online resources linked through the website are still functioning, including eFiling and eService, the Court Payment Center and remote access to district and appellate court records. The website was down for several hours from Dec. 21 to 31 in the previous attacks. “In a DDOS attack, an outside entity attempts to overwhelm an online resource with so much network traffic that it is no longer accessible to legitimate users,” State Court Administrator Jeff Shorba said in a January statement about last year’s attacks. “During these attacks, the Minnesota Judicial Branch did not experience any form of data breach or inappropriate access to court records, nor is there any evidence to suggest that the attackers attempted to gain access to Judicial Branch records or information.” Those attacks were reported to the federal government and Canadian authorities. “DDoS attacks are becoming increasingly common against high-profile websites in both the public and private sectors,” Shorba said in January. “While we cannot prevent these attacks from being launched, the Minnesota Judicial Branch is now better prepared to respond to these types of attacks in the future.” Source: http://www.startribune.com/minnesota-courts-website-attacked-again-by-hackers/384003231/

The central banks of Indonesia and South Korea are reportedly bulking up security on their public-facing websites after being hit with cyberattacks and distributed-denial-of-service (DDoS) disturbances linked to notorious hacking collective Anonymous. In response to the attempted cyberattacks, Ronald Waas, deputy governor of Bank Indonesia (BI), told Reuters his institution was forced to block 149 regions that don’t usually access its website, including “several small African countries”. The central banks of Indonesia and South Korea are reportedly bulking up security on their public-facing websites after being hit with cyberattacks and distributed-denial-of-service (DDoS) disturbances linked to notorious hacking collective Anonymous. In response to the attempted cyberattacks, Ronald Waas, deputy governor of Bank Indonesia (BI), told Reuters his institution was forced to block 149 regions that don’t usually access its website, including “several small African countries”. As previously reported, a video statement posted to YouTube on 4 May by the group said: “We will not let the banks win, we will be attacking the banks with one of the most massive attacks ever seen in the history of Anonymous.” Later, the central bank of Greece admitted its website was taken offline for a short period of time. This was followed by other banks in countries including France, England, Scotland and Sweden. In June, the hackers announced that ‘phase three’ of the operation has started – dubbed Project Mayhem – and that the focus of the campaign would change to include major stock exchanges. In any case, the global banking system has been left shaken by a number of successful hacks, breaches and cyber-heists throughout 2016. In one attack, the Bangladesh central bank was targeted by a highly coordinated team of hackers that were able to steal a massive £81m via fraudulent money transfers.

A single attacker has mounted two massive account takeover (ATO) campaigns against a financial institution and an entertainment company earlier this year, and used a gigantic botnet comprised of home routers and other networking products to do it. “ATO attacks (also known as credential stuffing) use previously breached username and password pairs to automate login attempts. This data may have been previously released on public dumpsites such as Pastebin or directly obtained by attackers through … More ?

We have all heard the stories of businesses which have suffered debilitating DDoS attacks and, in some cases, succumbing altogether. Take Code Spaces, the web-based SVN and Git hosting provider which suffered such an attack in June 2014 that it was forced to wave the white flag and cease trading after recovering all the data lost would cost too much. Now, a new piece of research from A10 Networks argues businesses face ‘sudden death’ from DDoS if caught unawares. The average company was hit by an average of 15 DDoS attacks per year, according to the survey of 120 IT decision makers, with larger organisations more badly affected. One in three (33%) respondents said they had encountered DDoS attacks of more than 40 Gbps, while one in five had suffered downtimes of more than 36 hours due to the attack. The average attack of those polled lasted 17 hours. More than half (54%) of respondents said they would increase their DDoS budgets in the coming six months, while multi-vector attacks were seen by the majority of those polled (77%) as the most dangerous form of DDoS threat in the future. “DDoS attacks are called ‘sudden death’ for good reason. If left unaddressed, the costs will include business, time to service restoration and a decline in customer satisfaction,” said A10 Networks CTO Raj Jalan. He added: “The good news is our findings show that security teams are making DDoS prevention a top priority. With a better threat prevention system, they can turn an urgent business threat into an FYI-level notification.” Previous research has examined the growing sophistication of DDoS threats. In April, Neustar argued that such DDoS issues were “unrelenting”, with more than seven in 10 global brands polled having been subject to an attack.

Businesses receive another warning over the threat of DDoS attacks
Juniper has disclosed that that a problem with the Junos router could enable DDoS attacks Juniper has admitted that a vulnerability in IPv6 processing on its Junos router OS could allow malicious packets to be sent to networks resulting in a DDoS attack on infrastructure. In an advisory, the firm said the flaw could enable a specially crafted “IPv6 Neighbor Discovery” (ND) packet to be accepted by the router rather than discarded. “The crafted packet, destined to the router, will then be processed by the routing engine (RE). A malicious network-based packet flood, sourced from beyond the local broadcast domain, can cause the RE CPU to spike, or cause the DDoS protection ARP protocol group policer to engage. When this happens, the DDoS policer may start dropping legitimate IPv6 neighbors as legitimate ND times out,” the firm said. The firm added that this is similar to the router’s response to any purposeful malicious IPv6 ND flood destined to the router. “The difference is that the crafted packet identified in the vulnerability is such that the forwarding controllers/ASICs should disallow this traffic from reaching the RE for further processing,” according to the advisory. It said that following investigations, only its MX, PTX, and QFX products have been confirmed to experience this behaviour. Juniper added that no fix was presently available at the time of writing and neither was a complete workaround. “Security best current practices (BCPs) of filtering all ND traffic at the edge, destined to network infrastructure equipment, should be employed to limit the malicious attack surface of the vulnerability,” the firm advised. Rich Barger, chief intelligence officer at ThreatConnect, told SCMagazineUK.com that organisations should look to either filter the protocol or packet (if possible). “It looks as if Juniper has included edge firewall rules that can block the neighbour discovery packets as a means to buffer any vulnerable devices,” he said. Richard Cassidy, technical director EMEA at Alert Logic, said that this flaw represents a serious issue for organisations that “Dual Stack” networking with IPv6 and IPv4. He told SC that the issue was “essentially a DDoS attack, through a specially crafted IPv6 ND packet, that can be targeted at JunOS routers from remote attackers. It is fairly simple to identify router OS versions through scanning techniques, which of course leaves most organisations at risk at some level, given the prevalence of Juniper in networking infrastructures globally.” Alex Cruz Farmer, VP of cloud at Nsfocus, told SC that almost every network around the world is considering or planning IPv6 if they have not already. “With this in mind, it’s crucial that the protection is implemented now, to avoid this security hole being exploited in future.” Source: http://www.scmagazineuk.com/flaw-in-junipers-junos-router-software-could-cause-ddos-flood/article/501681/

Nineteen attacks that exceeded 100Gbps were recorded during the first three months of 2016 There were 19 distributed denial-of-service (DDoS) attacks that exceeded 100 Gbps during the first three months of the year, almost four times more than in the previous quarter. Even more concerning is that these mega attacks, which few companies can withstand on their own, were launched using so-called booter or stresser botnets that are common and cheap to rent. This means that more criminals can now afford to launch such crippling attacks. “In the past, very few attacks generated with booter/stresser tools exceeded the 100 Gbps mark,” researchers from Akamai said in the company’s State of the Internet security report for the first quarter of 2016 that was released Tuesday. By comparison, only five DDoS attacks over 100 Gbps were recorded during the fourth quarter of 2015 and eight in the third quarter. Nineteen such attacks in a single quarter is a new high, with the previous record, 17, set in the third quarter of 2014. But high bandwidth is not the only aspect of DDoS attacks that can cause problems for defenders. Even lower-bandwidth attacks can be dangerous if they have a high packet rate. A large number of packets per second poses a threat to routers because they dedicate RAM to process every single packet, regardless of its size. If a router serves multiple clients in addition to the target and exhausts its resources, that can cause collateral damage. According to Akamai, in the first quarter there were six DDoS attacks that exceeded 30 million packets per second (Mpps), and two attacks that peaked at over 50 Mpps. DDoS reflection and amplification techniques continue to be used extensively. These involve abusing misconfigured servers on the Internet that respond to spoofed requests over various UDP-based protocols. Around one-in-four of all DDoS attacks seen during the first three months of 2016 contained UDP (User Datagram Protocol) fragments. This fragmentation can indicate the use of DDoS amplification techniques, which results in large payloads. The four next most common DDoS attack vectors were all protocols that are abused for DDoS reflection: DNS (18 percent), NTP (12 percent), CHARGEN (11 percent) and SSDP (7 percent). Another worrying trend is that an increasing number of attacks now use two or more vectors at the same time. Almost 60 percent of all DDoS attacks observed during the first quarter were multivector attacks: 42 percent used two vectors and 17 percent used three or more. “The continued rise of multi-vector attacks suggests that attackers or their attack tools are growing more sophisticated,” the Akamai researchers said in their report. “This causes problems for security practitioners, since each attack vector requires unique mitigation controls.” China, the U.S. and Turkey were the top three countries from where DDoS attack traffic originated, but this indicates where the largest number of compromised computers and misconfigured servers are located, not where the attackers are based. The most-hit industry was gaming, accounting for 55 percent of all attacks. It was followed by software and technology (25 percent), media and entertainment (5 percent), financial services (4 percent) and Internet and telecommunications (4 percent). Being hit by one isn’t the only way DDoS attacks can affect businesses: They can also be blackmailed with the threat of one, an increasing trend over the past year. In some cases attackers don’t even have to deliver on their threats. Researchers from CloudFlare reported recently that an extortion group earned $100,000 without ever launching a single DDoS attack.

Anonymous hacktivists take down the London Stock Exchange website for more than two hours as part of protest against world’s banks The online hacktivist group, Anonymous reportedly shut down the London Stock Exchange (LSE) website last week for more than two hours as part of a protest against world’s banks and financial institutions. According to the Mail on Sunday, the attack was carried out by Philippines unit of Anonymous on June 2 at 9am. Previous targets have included the Bank of Greece, the Central Bank of the Dominican Republic and the Dutch Central Bank. The newspaper says: “Anonymous claims the incident was one of 67 successful attacks it has launched in the past month on the websites of major institutions, with targets including the Swiss National Bank, the Central Bank of Venezuela and the Federal Reserve Bank of San Francisco.” A spokesperson for the LSE declined to comment on the incident, however, the attack most likely took the form of a distributed denial of service (DDoS) attack, meaning trading would not have been affected and no sensitive data would have been compromised. In the 24 hours before the LSE site went down, the group also claims that the attack on the LSE was the latest in a series that has also seen it target the websites of NYSE Euronext, the parent company of the New York Stock Exchange and the Turkey Stock Exchange, as part of a campaign called Operation Icarus. According to the newspaper, City of London Police said it was not informed that the LSE website had gone down and had no knowledge of the attack. However, the latest attack may not be a complete surprise. In a video posted to YouTube on May 4, a member of the amorphous group announced in that “central bank sites across the world” would be attacked as part of a month-long Operation Icarus campaign. The video statement said: “We will not let the banks win, we will be attacking the banks with one of the most massive attacks ever seen in the history of Anonymous.” By using a distributed-denial-of-service (DDoS) cyberattack, the group also successfully disrupted the Greek central bank’s website. In light of that event, a separate video was posted to YouTube on May 2. The masked individual representing Anonymous group said: “Olympus will fall. How fitting that Icarus found his way back to Greece. Today, we have continuously taken down the website of the Bank of Greece. Today, Operation Icarus has moved into the next phase.” The Anonymous spokesperson added: “Like Icarus, the powers that be have flown too close to the sun, and the time has come to set the wings of their empire ablaze, and watch the system their power relies on come to a grinding halt and come crashing down around them. We must strike at the heart of their empire by once again throwing a wrench into the machine, but this time we face a much bigger target – the global financial system.” Source: http://www.techworm.net/2016/06/anonymous-ddos-shutdown-london-stock-exchange-two-hours.html

Russia’s three largest Russian banks – VTB, Sberbank and Bank of Moscow – came under a massive DDoS-attack in the fall of 2015, a top manager at VTB has said. Claiming the attackers demanded a bitcoin payment for stopping the attack. A senior official from one of Russia’s largest banks has revealed that the lender became the target of the most extensive DDoS-attack in the entire history of monitoring in the fall of 2015. “A certain group of perpetrators” carried out a series of “the strongest DDoS-attacks” against Sberbank, VTB and Bank of Moscow for several days, Dmitry Nazipov, senior vice president of VTB, told the Russian media on June 1. According to him, the bank received a “fairly typical letter” in English at that time demanding a bitcoin payment in return for stopping the attacks. “Obviously, we did not agree to pay, but that attack was generally localized in three days, and was not repeated on such a scale thereafter,” said Nazarov. He pointed out that to solve the problem, VTB collaborated with police, telecom service providers and the Central Bank’s information security center, FinCert. In September 2015, the deputy head of the Central Bank’s main security and information protection directorate, Artyom Sychev, said that the websites of five major Russian banks had been subjected to a DDoS-attack. He did not disclose the names of the banks. Sychev said that after the end of the attacks, some of the banks attacked received letters from extortionists who demanded that 50 bitcoins (the average value of a bitcoin was around $230 in September 2015 – RBTH) be transferred to them for not repeating such attacks. He noted that the banks did not suffer damage as a result of the attack. Earlier on June 1, the Federal Security Service and the Interior Ministry reported the detention of 50 suspects in a theft of 1.7 billion rubles ($25 million) from financial institutions. The police also said that they could prevent 2.2 billion rubles’ ($32.5 million) worth of possible damage. The law enforcement agencies turned to security software producer Kaspersky Lab for help in identifying the suspects. According to the company, the hackers stole 3 billion rubles ($44.5 million). Six Russian banks, including Metallinvestbank, the Russian International Bank, Metropol and Regnum, were victims of the hackers.
