Hackers are exploiting SQL injection flaws to infect MySQL database servers with a malware program that’s used to launch distributed denial-of-service (DDoS) attacks. Security researchers from Symantec found MySQL servers in different countries infected with a malware program dubbed Chikdos that has variants for both Windows and Linux. Don’t count on your ‘plain vanilla’ resume to get you noticed – your resume needs a personal flavor to This Trojan is not new and was first documented in 2013 by incident responders from the Polish Computer Emergency Response Team (CERT.PL). At that time the malware was being installed on servers after using brute-force dictionary attacks to guess SSH (Secure Shell) login credentials. However, the new attacks observed by Symantec abuse the user-defined function (UDF) capability of the MySQL database engine. UDF allows developers to extend the functionality of MySQL with compiled code. Symantec believes that attackers exploit SQL injection vulnerabilities in order to inject malicious UDF code in databases. They then use the DUMP SQL command to save the injected code as a library file that is later executed by the MySQL process. The malicious UDF code downloads and installs the Chikdos Trojan, which allows attackers to abuse the server’s bandwidth for DDoS attacks. The Symantec researchers found MySQL servers infected with Chikdos in many countries, including India, China, Brazil, Netherlands, the U.S., South Korea, Mexico, Canada, Italy, Malaysia, Nigeria and Turkey. The largest concentrations were in India and China, 25 and 15 percent respectively. During their analysis the researchers saw the servers being used to launch DDoS attacks against a U.S. hosting provider and a Chinese IP address. The reason for targeting MySQL servers is likely because their bandwidth is considerably larger than that of regular PCs, making them more suitable for large DDoS campaigns, the Symantec researchers said in a blog post. To prevent such attacks, website owners should avoid running SQL servers with administrative privileges and should follow best programming practices for mitigating SQL injection vulnerabilities, they said.

Attackers are turning MySQL servers into DDoS bots
Faced with a wave of DDoS attacks, a horde of hackers claiming to be Anonymous and major data leaks from state-owned CAT Telecom all in protest of Thailand’s Single Gateway surveillance program, ICT Minister Uttama Savanayana took to Twitter to reassure people that everything was in order and that we had nothing to fear because we have regular data backups. Yes, apparently regular backups and standards in data storage are the answer to a hack and data leak. The tweet was up for most of the weekend before he deleted it to save himself further embarrassment. To recap, a group claiming to be Anonymous issued a statement in the wee hours of Thursday morning to attack the Thai Government and in particular CAT Telecom for refusing to back down on Single Gateway internet super censorship and surveillance project which, despite promises from the Prime Minister that it was just a clerical error never existed, is forging ahead full steam. Since then at various moments, hackers have managed to temporarily take down an obscure army internal accounting website, the ICT Ministry and CAT Telecom. The Anons also posted screenshots of what they claimed was CAT customer data with names blanked out, taunting the ICT Minister by asking what data standard allows for plaintext storage of passwords. CAT Telecom initially responded by saying the information posted was false and that the hackers only tried to infiltrate CAT’s dealer network and did so unsuccessfully at that. The Anons responded with more CAT customer data and a screenshot of a login in CAT’s CRM module. One would have thought that this would have caused the junta to think twice about centralizing everything but no. The ICT Minister had the stage in the weekly two-minutes of hate propaganda show, sorry, I meant Thailand Moves Forward propaganda show, in which he extolled the virtues of a single Geoment Service Chanel [sic] which called for even more centralization. Half the jokes were of using designer clothing to serve the people the other, well, let’s just say that geo in Thai is a anatomical word that would not befit the pages of this publication. So apparently not only he totally clueless as to what a modern day hack is (by saying that he had backup) but he cannot use a spell checker. By Sunday, CAT’s My 3G self-service portal was still down, though whether it was from the attack or if someone pulled the plug as a precaution was anyone’s guess. However, that hardly made the social media circles. Why? Well, because despite oodles of taxpayer cash (roughly $1 billion each for CAT and TOT for their 3G networks, plus who knows how much more to run the network), CAT and TOT have between them less than 100,000 subscribers, none of which bothered to check their balance or top up over the weekend, it seemed. Also noteworthy was how servers in CAT’s data center had their latency and jitter both jump but again, that could be a routing issue rather than someone installing deep-packet-inspection gear. But was the hack actually from a real Anon? Anonymous is more of a state of mind that a club with a for formal job interview and membership cards. Anyone can claim to be an Anon. Their key tenets are anti-surveillance and anti-censorship, both of which the Thai Single Gateway are aimed at imposing. One developer who did not want to be identified told TelecomAsia that the hacks on Thai government websites were simply too easy. He sent a screenshot with a page of .go.th sites with old, unpatched mysql servers that were ripe for taking over. His point being, a script kiddie noob could have carried out hacks on these government websites and it did not require the skills of a true Anon. Source: http://www.telecomasia.net/blog/content/thai-govt-website-ddosed-cat-customer-data-leaked DDoS? Well, considering that Thai government websites cannot even stand up to use on a busy day without crashing, again, that hardly requires serious firepower. The CAT data breach also happened about a month ago if the rumors in the underground are to be believed. Talking about the underground, none of my shadier contacts know who did it the attack. Considering the rather small size of the Thai hacking community, this is odd. To further throw doubt on everything, the F5 hackers dared me over Twitter to double check a phone number in the CAT data breach to see if the data was real or made up. I did call up the number and he had no clue about being hacked and said he was not a CAT customer. Not looking good for the hackers then. To be fair I did try to ask if he was working at the company he was listed as working for but the chap hung up on me first, obviously annoyed at my questions. But perhaps the number had been reused (the phone line application with CAT was way back in August 2014), perhaps he never got the phone line and had totally forgot about it. Or maybe it was made-up data and the hacker thought I would not call to fact-check. At this juncture, my gut feeling is leaning towards this entire episode being a honey trap to lure out dissenters and convince the undecided of the need to give up further liberties so that the government can protect us from Anonymous. If so, that has worked wonders. Then there is the separate matter of the 231 pages of leaked documents that are a headache just to try and read through. Who leaked them and why? It is a curious mix of army and MICT secret documents which begs the question, who would even have access to both sets of documents in the first place? Very few. But regardless as to whether this initial hack was real or staged, the matter of the Thailand’s Single Gateway has now reached the eyes of Anons the world over. One wonders if they are planning a real attack soon.

Thai govt website DDoSed as CAT customer data leaked
Default and weak credentials on embedded devices can lead to powerful botnets We’ve reached a point that security researchers have long warned is coming: Insecure embedded devices connected to the Internet are routinely being hacked and used in attacks. Want to add a bunch of users without going out of your mind? We show you how to do that, and more. The latest example is a distributed denial-of-service (DDoS) attack detected recently by security firm Imperva. It was a traditional HTTP flood aimed at overloading a resource on a cloud service, but the malicious requests came from surveillance cameras protecting businesses around the world instead of a typical computer botnet. The attack peaked at 20,000 requests per second and originated from around 900 closed-circuit television (CCTV) cameras running embedded versions of Linux and the BusyBox toolkit, researchers from Imperva’s Incapsula team said in a blog post Wednesday. When analyzing one of the hijacked cameras that happened to be located in a store close to the team’s office, the researchers found that it was infected with a variant of a known malware program designed for ARM versions of Linux that’s known as Bashlite, Lightaidra or GayFgt. While infecting computers with malware these days requires software exploits and social engineering, compromising the CCTV cameras that were used in this attack was very easy as they were all accessible over the Internet via Telnet or SSH with default or weak credentials. Insecure out-of-the-box configurations are a common issue in the embedded device world and have been for a long time. In 2013, an anonymous researcher hijacked 420,000 Internet-accessible embedded devices that had default or no login passwords and used them in an experiment to map the whole Internet. However, the problem is getting worse. The push by device manufacturers to connect things such as refrigerators or “smart” light bulbs to the Internet is largely done without consideration for security implications or an overhaul of outdated practices. As a result, the number of easily hackable embedded devices is growing fast. Shortly after the CCTV camera-based attack was mitigated, a separate DDoS attack was detected that originated from a botnet of network-attached storage (NAS) devices, the Imperva researchers said. “And yes, you guessed it, those were also compromised by brute-force dictionary attacks.” Source: http://www.computerworld.com/article/2996079/internet-of-things/attackers-hijack-cctv-cameras-to-launch-ddos-attacks.html

There was a major distributed-denial-of-service (DDoS) attack on Rossiya Segodnya International Information Agency resources, including the Sputnik website and newswire, the company’s IT department said Saturday. The attack restricted access to desktop and mobile versions of the Sputnik website. IT specialists managed to ensure the timely release of news pieces to the newswire clients. The agency’s press service said that IT specialists were working to establish the details of the attack that restricted access to desktop and mobile versions of the Sputnik website. “Rossiya Segodnya websites and mailing services were unavailable to users for two hours starting at 7:00 p.m. Moscow time [16:00 GMT],” the press service said. DDoS attacks are caused by a large number of Internet users or software simultaneously sending requests to a website until it exceeds its capacity to handle Internet traffic. The Sputnik site was unavailable for almost two hours. Source: http://sputniknews.com/art_living/20151017/1028682238/sputnik-ddos-attack.html

Android users running AT&T and Verizon networks may be susceptible to distributed denial of service (DDoS) attacks. The alert comes from a new advisory posted by Carnegie Mellon University CERT database, which shows that the vulnerability allows hackers to target LTE networks and users. The reason for this vulnerability is primarily due to the way LTE works. Unlike conventional data transfer methods of circuit switching, LTE uses packet switching. The research says that this new method allows hackers to use the SIP protocol to enable a new set of attack vectors via wireless networks. If this loophole is exploited, denial of service attacks can be carried out on these networks and data exploitation along with ‘silent calls’ can be executed, allowing for unlimited phone calls and use of large amounts of data without any records of them in bills. According to the researchers, every Android OS version released to date could be affected by this vulnerability. Google has already been notified about this massive flaw, and has been advised to escalate its permissions on Android. Apple on the other hand has said that its phones aren’t affected by this LTE security flaw. Google itself is likely to release a security update very quickly for its supported Nexus devices to take counter-measurements against the issue. If you have a carrier-provided phone from LG, Samsung, or other brands however, chances are you’ll have to wait a while. Carriers are notorious for releasing updates on snail-like pace.

Android Devices Affected By LTE Security Flaw, Could Result in DDoS Attacks
Continuing our exclusive coverage of the events unfolding at forex solutions provider oneZero, LeapRate has learned that the outages hitting oneZero and thereby some of its hosted clients over the past week are the result of distributed denial-of-service (DDoS) attacks being made against the company. After engaging multiple security contractors, the company has isolated the attacks and has determined that they originate out of China. A distributed denial-of-service (DDoS) attack is an attempt to make a machine or network resource unavailable to its intended users. It is the result of multiple compromised systems (for example a botnet) flooding the targeted system – usually one or more web servers – with traffic. The most serious attacks are distributed, meaning that the attack source is more than one (and often thousands) of unique IP addresses. Many of the cases involve forging of IP sender addresses (IP address spoofing) so that the location of the attacking machines cannot easily be identified, nor can filtering be done based on the source address. For these and other reasons, DDoS attacks are typically very effective and difficult to mitigate. oneZero management indicated to LeapRate that the attack against them has been made with a very high level of sophistication, but that the company is working very closely with security contractors and with its clients and expects the situation to be resolved. The attack against oneZero appears to be solely targeting connectivity, and has not at all affected the company’s own systems, so that no company or client data has been compromised. And so far, there has been no attempt to exploit the attack – DDoS hackers often try to blackmail their targets, requiring some sort of ransom to be paid in order to remove the attacks.
