Trend Micro - Security Intelligence
While ransomware has noticeably plateaued in today’s threat landscape, it’s still a cybercriminal staple. In fact, it saw a slight increase in activity in the first half of 2018, keeping pace by being fine-tuned to evade security solutions, or in the case of PyLocky (detected by Trend Micro as RANSOM_PYLOCKY.A), imitate established ransomware families and ride on their notoriety.
In late July and throughout August, we observed waves of spam email delivering the PyLocky ransomware. Although it tries to pass off as Locky in its ransom note, PyLocker is unrelated to Locky. PyLocky is written in Python, a popular scripting language; and packaged with PyInstaller, a tool used to package Python-based programs as standalone executables.
