PyLocky represents a new ransomware strain that was detected in the wild in late July 2018, and whose volume of infections increased throughout the month of August. The malware is usually distributed through malspam emails claiming to link to a fake payment invoice, and it features advanced anti-detection and anti-sandbox capabilities. Notably, infection telemetry data shows that PyLocky mainly targeted France and German cyberspace, but ransom notes also exist in Italian and Korean.
On September 11, 2018, we detected the leakage of PyLocky source code on Pastebin. Thus far, the incident has not received media attention. However, the paste was viewed by over 2,500 users. Therefore, our assessment is that this leakage might lower the barrier to entry for wannabe cybercriminals, possibly leading to an increase in malspam campaigns distributing this malware strain in the future.
