Maritime-Theme Phishing Emails Spread NanoCore RAT
A phishing campaign is spreading the NanoCore remote access tool (RAT) by using emails crafted to look like shipping information from a reputable logistics company. The spam emails contain a specially crafted ZIP attachment that has two archive structure. The first ZIP structure is for a fake order image file while the second ZIP structure is an executable that installs the NanoCore RAT. Most file extractors will only be able to extract the harmless image file and only certain versions of the PowerArchiver, WinRar, and older 7-Zip utilities are able to properly extract the NanoCore executable. Nanocore is a community RAT that is available for as little as US$25. It is modular and can incorporate features such as keylogger, data exfiltration and screen locker.
