Avalanche (phishing group)

Avalanche was a criminal syndicate involved in phishing attacks, online bank fraud, and ransomware. The name also refers to the network of owned, rented, and compromised systems used to carry out that activity. Avalanche only infected computers running the Microsoft Windows operating system.

In November 2016, the Avalanche botnet was destroyed after a four-year project by an international consortium of law enforcement, commercial, academic, and private organizations.
