VERY IMPORTANT

Proofpoint researchers have discovered a previously undocumented remote access Trojan (RAT) called FlawedAmmyy that has been used since the beginning of 2016 in both highly targeted email attacks as well as massive, multi-million message campaigns. Narrow attacks targeted the Automotive industry among others, while the large malicious spam campaigns appear to be associated with threat actor TA505, an actor responsible for many large-scale attacks since at least 2014.
