Details of these detection strategies, including their corresponding OpenSignature rules are provided below. SMB Transfer of Encoded Track Data The first detection strategy takes advantage of the fact that the first 15 characters of the stolen track data always consist of digits, this means that the first 5 groups of encoding output which is 4 bytes each has a fairly limited number of combinations and therefore has a predictable pattern. Digital forensic investigators and information security researchers have positively identified the malware used in the recent attack against Target. The malicious code infected point-of-sale POS terminals at the retailer and then helped transfer the stolen data to an FTP server in Russia. The attack against Target, which began in late November and continued until mid-December, resulted in the theft of 40 million credit and debit cards as well as personal information for as many as 70 million customers.

Digital forensic investigators and information security researchers have positively identified the malware used in the recent attack against Target.

The malicious code infected point-of-sale POS terminals at the retailer and then helped transfer the stolen data to an FTP server in Russia.

The attack against Target, which began in late November and continued until mid-December, resulted in the theft of 40 million credit and debit cards as well as personal information for as many as 70 million customers.

The malware reportedly includes some Russian-language tags, and was also used in a smaller series of apparent trial attacks last year, after which stolen data appeared on Eastern European cybercrime forums. Those facts have led some investigators to surmise that whoever attacked Target might be operating from either Russia or a former Soviet satellite.

If so, the malware would create a temporary NetBIOS share and connect to another internal, compromised system, from which the FTP transfer then occurred, Wired reported. On Dec.

Secret Service and other government agencies investigating the breaches. Security journalist Brian Krebs, who broke the story about the Target and Neiman Marcus attacks, previously reported correctly that the malware used against Target was based on BlackPOS. According to iSight, which has seen the government report but would not release it, the attackers also used a variety of other malicious tools to penetrate networks, maintain a persistent foothold on them and extract stolen data.
