- SteamStealer, a malware distributed through the Steam gaming platform. The distribution of the malware is done by sending malicious files through the platform chats, which then install the malware once opened. The malware can steal Steam credentials and in turn access the user’s financial information used on the platform.
- Cerber, a malware that debuted in late February of 2016, has already become one of the most prevalent ransomware variants. Typically, it is distributed via emails containing macro-enabled Word documents, Windows Script Files, or Rich Text Documents. Cerber uses a strong, currently unbreakable encryption, and has a number of features that, when combined, make it unique in today's ransomware landscape. A new version of the ransomware potentially gives it DDOS capabilities. One recent variant of the ransomware has been spotted quietly sending out huge amounts of network traffic from infected machines.

This malware is distributed by identifying vulnerable devices using a table of common factory default usernames and passwords, then logging into them in order to infect them. This botnet has been used in the recent large DDoS attacks against computer security journalist Brian Krebs' web site, and in the October 2016 Dyn cyber-attack.
