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 […]

Security Hole in Samsung Smart TVs Could Allow Remote Spying

The company that made headlines in October for publicizing zero day holes in SCADA products now says it has uncovered a remotely exploitable security hole in Samsung Smart TVs. If left unpatched, the vulnerability could allow hackers to make off with owners’ social media credentials and even to spy on those watching the TV using compatible video cameras and microphones. In an e-mail exchange with Security Ledger, the Malta-based firm said that the previously unknown (“zero day”) hole affects Samsung Smart TVs running the latest version of the company’s Linux-based firmware. It could give an attacker the ability to access any file available on the remote device, as well as external devices (such as USB drives) connected to the TV. And, in a Orwellian twist, the hole could be used to access cameras and microphones attached to the Smart TVs, giving remote attacker the ability to spy on those viewing […]

FBI Issued Alert over July Attack on HVAC System

The FBI issued an alert to businesses in July after unknown attackers breached a computer used to control the heating, ventilation and air conditioning (HVAC) system of a New Jersey company, accessing a graphical user interface for the system, including a floor play layout of the company’s office. The attacks came after an Anonymous affiliated hacker, using the handle @ntisec, published links to vulnerable ICS systems running software from the firm Tridium online. The links included the address of an administrative system that controlled the HVAC system used by US Business 1, a New Jersey company that installs air conditioning systems for other companies, according to a copy of the July, 2012 Situational Information Report (PDF), issued by the Newark Division of the FBI. The alert concerning the February and March, 2012 attack was released by the web site Public Intelligence on Saturday. The FBI did not respond to a request for comment from Security […]

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.

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 […]

Chrome 0Day A No-Show At Security Con

A planned talk that was to unveil a new and previously unknown (or “zero day”) vulnerability in Google’s Chrome web browser was cancelled on Saturday after the researcher, Ucha Gobejishvili, backed out, citing difficulties obtaining a visa to travel to New Dehli, India, where the Malcon hacking conference was held. The organizer of Malcon, Rajshekhar Murthy, confirmed in an email to Security Ledger that Gobejishvili cancelled his talk at the last minute. “(Ucha) did not come at (sp) the conference due to visa issues in the last minute,” Rajshekhar Murthy wrote in an e-mail to Security Ledger on Monday. “The issue stated was he was called in last minute (sp) by the military for compulsory service which conflicted with our event dates.” Gobejishvili did not respond to e-mail and instant message requests for comment. In a conversation with Security Ledger last week, he said he would use his talk at […]
