Executive Summary
In January 2015, the "LizardStresser" DDoS-for-hire service run by the Lizard Squad group was itself breached, publicly exposing over 13,000 user accounts with passwords stored in plaintext. The users were customers of the illegal stresser/booter service.
ObscureIQ assessment: Risk is unusually layered. The breach may expose both users of the illicit service and operational details of the malicious infrastructure itself. That creates not only credential and fraud risk, but also reputational, legal, retaliatory, and deanonymization concerns for participants in the ecosystem.
Breach Impact
The main significance is deanonymization of people who paid for a DDoS-for-hire service; plaintext passwords also expose reused credentials.
