Quantum Booter Data Breach

What happened

In March 2014, the booter service Quantum Booter (also referred to as Quantum Stresser) suffered a breach which lead to the disclosure of their internal database. The leaked data included private discussions relating to malicious activity Quantum Booter users were performing against online adversaries, including the IP addresses of those using the service to mount DDoS attacks.

• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Quantum Booter — attackers weaponise breach data quickly.
