  • Mirai, a Linux malware targeting IoT systems, is mainly used for DDoS attacks. This malware is distributed by identifying vulnerable devices using a table of common factory default usernames and passwords, subsequently logging in and infecting them. This botnet was used in the recent DDoS attacks against computer security journalist Brian Krebs' web site, as well as in the October 2016 Dyn cyber-attack. You can read more on our blog, here.
  • Cobalt Kitty, defined as an APT (by CybeReason) targeting a global corporation based in Asia, aims to steal proprietary business information.

The attackers compromised more than 40 PCs and servers, including the domain controller, file servers, Web application server and database server. This campaign was not completely attributed, but had signs linking this actor to OceanLotus (Also known by the names APT-C-00, SeaLotus and APT32)
  • HIDDEN COBRA are cyber actors attributed to North Korean government. The malware variant (DeltaCharlie) used to manage their distributed denial-of-service (DDoS) botnet infrastructure is likely also used for network exploitation.
  • TrickBot is the successor of This malware is distributed through spam emails and the threat loader 'TrickLoader.' TrickLoader is associated with several other threats, including Pushdo, Cutwail and Vawtrak. The primary target of this malware is credential theft.
