17 year old fingered as author of malware used in Target attack

A 17 year old Russian hacker who goes by the online handle of "ree4" has been identified as the author of the malware that was used to attack Target and Neiman Marcus.

The teenager, Sergey Taraspov, is well known in cyber crime circles having developed other malicious codes to hack commercial systems. He apparently sold about 40 copies of his program to criminals who then modified it slightly and used it to sweep up at least 80 million debit and credit card numbers from Target alone.

Now, the firm that first revealed the Target attack, is saying that 6 other companies suffered a similar fate.

....International Business Times is reporting that the 6 other companies targeted in the hack have not informed their customers yet:

Retailers in California and New York were among those hacked with kARTOXA/BlackPOS, the software used in the attack on Target.

Security researchers at the Los Angeles-based IntelCrawler said the teen malware author created the first sample of the software in March 2013. Komarov issued the first report on this malware in the beginning of the spring, when he worked for another forensics company.

Komarov also said in an email to the IBTimes that there is evidence of more than six ongoing attacks, but that he cannot yet release more information.

"We will report with the first feedback and approval from [law enforcement authorities]," Komarov said.

IntelCrawler describes itself as a "a multi-tier intelligence aggregator, which gathers information and cyber prints from a starting big data pool of over 3,000,000,000 IPv4 and over 200,000,000 domain names, which are scanned for analytics and dissemination to drill down to a desired result."
