Cyber criminals are notoriously crafty and persistent, especially when it comes to defeating security measures created to thwart them. But a group behind a recent version of the Ramnit banking malware has raised their game to a new level: hacking the customer FAQ (frequently asked questions) document to make their malicious activity look like it was business-as-usual. A report on Tuesday by the security firm Trusteer finds that new variants of Ramnit targeting a UK bank have added features to game a one-time-password (OTP) feature at the bank. Among other tricks, the Ramnit variant uses an HTML injection attack to alter the wording of the bank’s customer FAQ, making it seem as if prompts created by the malware were standard security features at the bank. The report, published on the Trusteer blog, described a complex ruse in which Ramnit lies dormant on infected machines, then springs to action once a […]

Botnet Of Embedded Devices Used To Map Internet
Botnets are mostly linked with spam e-mail campaigns, denial of service attacks and data theft. But global networks of compromised hosts can be used for a variety of ends – not all of them malicious. That was the idea behind “Internet Census 2012,” a stealth project by an unnamed and unknown researcher/hacker to map the entire IPV4 Internet address space using a massive network of compromised devices. The results, published in the form of a research paper, underscore the problem of unsecured embedded devices, including set top boxes, home routers and critical infrastructure, with the hacker able to locate and compromise these systems, creating a botnet of more than 420,000 nodes. According to a copy of the report, the project grew out of an experiment to locate unprotected devices online using nmap, the open source scanning tool. By compromising each vulnerable host and then enlisting it to scan for other […]
New York Times Hack Puts Antivirus on Defensive
The big news this morning is the New York Times’ scoop on…well…itself. According to a report in today’s paper, the Times’s computer network was compromised for more than four months by attackers believed to be located in China. The attacks followed a Times exposé on the wealth accumulated by family members of China’s prime minister, Wen Jiabao – one of a series of reports in Western media outlets that raised questions about corruption and influence peddling in China’s ruling Communist Party. Attackers planted 45 pieces of information-stealing malware on Times systems, despite the presence of antivirus software from Symantec Corp. protecting those systems before, during and after the hack. The story is fueling debate about the value of anti-virus software and prompted Symantec to issue a statement defending its technology, but warning that signature-based antivirus is not enough to stop sophisticated attacks. According to the Times report, the attacks used compromised systems on […]
Tantalizing Clues in Dexter Malware Lead to Mystery Man…and Zeus
The Dexter malware is getting some media attention this week – and not just because the malware shares its name with Showtime’s popular drama about a serial killer by the same name. (Not that those of us tasked to write catchy headlines don’t love stuff like that – ’cause we do.) No, the Dexter virus caught the attention of malware analysts because it infects point of sale (POS) systems like electronic cash registers, kiosks and automatic teller machines (ATMs), rather than run of the mill laptops and desktops. It has also generated some interest because it uses a form of memory dump parsing to steal sensitive data from infected POS terminals, and because its POS malware that is part of a botnet – communicating back to a command and control system and receiving commands – that’s quite unusual and, while its kind of insider baseball for malware geeks, it makes […]
Web Attacks Target Foreign Exchange, Payment Processing Sites
A currency trading web site was compromised and used to serve malicious java applications to unwitting visitors, according to researchers at the security firm Websense- part of what might be a larger trend. Websense said in a blog post on Wednesday that the site tradingforex.com, which is used by foreign currency traders, was infected with a malicious Java applet that, when installed, key logging and screen capture software. Tradingforex.com (@Tradingforexxx) is a Cyprus-based online trading web site. It allows individuals to trade on the global foreign exchange market (or Forex). Users can trade everything from foreign currencies to precious metals, commodities and other financial instruments. According to an investigation by Websense researcher Gianluca Giuliani, the site was pushing a back door program to visitors using a malicious Java plugin to exploit known Java vulnerabilities on the victims’ computers. Further investigation by Websense and Giuliani revealed that the malware being pushed […]
