Detecting IcedID attacks


IcedID is a banking trojan campaign. This malware is seen in Windows environments where it initially uses MS Office as a weapon or attack vector to infect machines, and then targets browsers such as Firefox and Chrome to steal online banking information. It is known for its unique payload downloaded in C2, where its .png file hides the core shellcode bot using stenography techniques or gzip dat files that contain "license.dat" - the actual core IcedID bot.
