Mylobot Malware Brings New Sophistication to Botnets


  • ransom-4


Security researchers found a new malware called MyloBot (detected by Trend Micro as TSPY_MYLOBOT.A) that features sophisticated evasion, infection, and propagation techniques, implying that the authors have the experience and heavy infrastructure behind them.

Discovered in the systems of an undisclosed Tier 1 data and telecommunications equipment company, the researchers observed MyloBot's behaviors include process hollowing, reflective EXE, code injection, ransomware payload, and data theft.

As it ropes in infected machines into a botnet, this new malware also removes all other malware from the system and inflicts extensive system damage.
