China online gambling bust; Korean site orders DDoS attacks on competitor

Authorities in China have broken up an international online gambling operation based in Hunan province. China’s official press agency Xinhua quoted Chinese police saying they’d detained 19 individuals following a two-month investigation. A further eight individuals have been targeted for arrest over their roles in the operation of the Shenbo Sun City website, whose servers were based outside the country. Police said the operation earned a profit of RMB 1.4b (US $$223m) between May 2013 and Oct 2014. Police have frozen approximately 1,000 bank accounts across China containing around RMB 200m. This marks China’s second major bust of 2015, having taken down a similarly large operation in Shandong province in January. Over in South Korea , authorities have arrested two ‘cyber security experts’ accused of targeting an online gambling site with distributed denial of service (DDOS) attacks. Intriguingly, the hackers were hired by another illegal online gambling operator intent on eliminating his competition. The Korea Times quoted the National Police Agency saying a man named Yang, the owner of an online security company, was paid a hefty KRW 1b (US $911k) since May 2014 to target the online gambling operator’s competitor on multiple occasions. Neither site operator was publicly identified by police. On Sept. 25, Yang reportedly hacked into 12k computers and commanded them to spam the targeted site with messages in order to crash its servers. Yang told police he’d agreed to don the black hat because his legal sources of income were “unstable.” Police are continuing to investigate to determine what other DDOS attacks Yang and his henchman might have launched.

DDoS attacks enabled via vulnerable Google Maps plugin

An industry warning has been issued to businesses and Software-as-a-Service providers advising that attackers are currently exploiting a vulnerable Google Maps plugin installed on Joomla servers to launch distributed denial of service (DDoS) attacks. “Vulnerabilities in web applications hosted by Software-as-a-Service providers continue to provide ammunition for criminal entrepreneurs. Now they are preying on a vulnerable Joomla plugin for which they’ve invented a new DDoS attack and DDoS-for-hire tools,” said Stuart Scholly, senior vice president and general manager at the Security Business Unit, Akamai Technologies. “This is one more web application vulnerability in a sea of vulnerabilities.” The vulnerability found in the Google Maps plugin for Joomla allows the platform to act as a proxy, enabling attackers to process fake requests and return the proxy results to a targeted user in the form of a DDoS attack. The source of the attack remains anonymous as the hack-related traffic appears to come from the Joomla servers. Figures released in February 2014 showed that Joomla, the second most frequently used online content management system after WordPress, had been downloaded over 50 million times. Working with Phishlab R.A.I.D, Akamai’s Prolexic Security Engineering and Research Team (PLXsert) were able to match the DDoS signature traffic coming from a number of Joomla sites, suggesting that the vulnerable plugins are currently being used to execute a large amount of reflected GET flood DDoS attacks. The research has also found that the attack vector is being advertised over popular DDoS-for-hire websites. PLXsert identified over 15,000 supposed Joomla reflectors online. Despite many of the vulnerable plugins having been patched, removed or reconfigures, many of the servers remain open to attack. Reflection techniques to conduct DDoS attacks are extremely common, with 39% of all DDoS traffic employing reflection to bounce malware off third-party servers and to hide the attackers’ identity.

DDoS Exploit Targets Open Source Rejetto HFS

Apparently no vulnerability is too small, no application too obscure, to escape a hacker’s notice. A honeypot run by Trustwave’s SpiderLabs research team recently snared an automated attack targeting users of the open source Rejetto HTTP File Server (Rejetto HFS). Someone was trying to exploit a vulnerability—which has since been patched—and install the well-known distributed denial-of-service tool IptabLes (unrelated to the Linux tool), also known as IptabLex. Rejetto HFS has been downloaded more than 24,000 times in the last seven days and according to the project’s website has an estimated 12,500 users and is used as a file-sharing application as well as a webserver. It also runs on Wine, the Windows emulator for Linux systems. “This is just one snapshot, one request. This is one example to extrapolate and take a higher level view; there’s likely a lot more activity out there,” said Ryan Barnett, SpiderLabs lead researcher. It’s likely the attackers have simply incorporated this exploit into a larger attack platform, Barnett said. “That’s the value of honeypots, spotting automated tools scanning the Internet shot-gunning exploits, and hoping it works,” Barnett said. The exploit, sent from a possible compromised IP address in China, was targeting CVE-2014-6287, a remote code execution bug in Rejetto. Specifically, the vulnerability affects Rejetto versions prior to 2.3c; the vulnerability is in the findMacroMarker function. Barnett said the exploit relies on a null byte character to trigger the attack code, which is written in Microsoft VBScript. Once the exploit executes, it tries to connect to a pair of IP addresses hosted in Paris (123[.]108.109.100 and 178[.]33.196.164) on three ports: 80 (HTTP); 53 (DNS); and 443 (HTTPS). Barnett said only 178[.]33.196.164 remains online and is a malware repository responding to XML HTTP Requests (XHR) from the exploit. The exploit tries to infect Rejetto users with the IptabLes DDoS tool. via @Threatpost Tweet A file called getsetup.exe is sent to the compromised server along with another executable, ko.exe, which drops IptabLes. Barnett said detection rates are high for the hash of getsetup.exe. IptabLes is a troublesome DDoS tool, capable of synflood and DNSflood attacks. It installs itself into boot for persistence, according to the SpiderLabs research, which added that IptabLes has been widely reported targeting Linux and Unix servers. The vulnerability being targeted was submitted last September. “It’s not very sophisticated, and a lot of times these types of attacks don’t have to be,” Barnett said. “These guys are concerned with scale because they’re running botnets. What makes botnets so nice to the criminals running them is that they don’t care to be stealthy. They can send attacks blindly, and if they’re shut down, they just move on.” Source: http://threatpost.com/ddos-exploit-targets-open-source-rejetto-hfs/111286

New York City hit with DDoS attacks, government email service knocked out

Unknown hackers knock out New York City governments email system For whole of last week and uptil Monday, unknown hackers had knocked of New York City government’s emailing system. The attack was pretty ferocious according to a City Hall source who said that the “universal” denial of service attack had now been contained but there was still “ongoing malicious activity” as recently as Monday. Almost all government agencies in New York City were unable to send or receive messages for the past week due to this attack. Some agencies such as the Department of Transportation set up temporary Gmail accounts to send and receive emails. Sources said that inbound and outbound emails were affected while intra-agency emails were not affected by the attack Speaking about the DDoS attack, Jackie Albano, a spokeswoman for the city’s Department of Information Technology and Telecommunications, said that the attack which started last Tuesday, had been resolved last week. He  also added that the efforts taken to mitigate the attack may have slowed the email servers resulting in slowed emails. It is not known whether New York City government websites were under DDoS attack or were hacked because Albano added that no sensitive information or data was compromised during the attack. He however said that this was a “big attack” but downplayed its impact on New York City government services. “It is a big deal but….it’s like a lot of mosquitoes buzzing around you,” said Albano. “The nature of the attack is only designed to interfere with service, not to steal or access any private information. It’s designed to slow down email. On the scale of cyber incidences it’s kind of low.” Albano said that MSISAC, New York Police Department and FBI were all investigating the incident and it is still not clear who initiated the attack of why.
