A PoC backdoor that uses Gmail as a C&C server
(ESET) [During the Sandworm analysis] We expected to see the BlackEnergy malware as the
final payload, but a different malware was used this time. The attackers used modified versions
of an open-source gcat backdoor written in the Python programming language. The python
script was converted into a stand-alone executable using PyInstaller program.
