Description
(Trend Micro) Based on our analysis of the malware, BKDR_DEXTR.A downloads files, sends information, and checks memory for in
others. But the centerpiece of the malware is its ability to collect and send certain information to a remote server. Some of the possible
stolen from POS systems include such as username, hostname, key to decrypt the sent information, OS information, and list of running
data are then presumably duplicated by remote malicious users.
The malware executable is found to be packed or encrypted and when loaded, it loads long garbage code to decrypt the actual code. Ho
decryption routine involves only a combination of XOR and ADD instructions, with the use of a hardcoded key. The perpetrators behin
probably done this to make analysis difficult.
