Russian Hacker Pleads Guilty to Developing and Distributing Citadel Trojan

Mar 23, 2017
A Russian man accused of developing and distributing the Citadel Banking Trojan , which infected nearly 11 Million computers globally and caused over $500 Million in losses, has finally pleaded guilty to charges of computer fraud. Mark Vartanyan, 29, who was very well known as " Kolypto ," pleaded guilty in an Atlanta courtroom on Monday to charges related to computer fraud and is now co-operating with federal prosecutors in return for a reduced sentence of no more than five years in prison. Vartanyan, a native of Moscow, was arrested in Norway in October 2014 and extradited to the United States in December last year. He was involved in the development, improvement, maintenance and distribution of the nasty Citadel Trojan.

Nov 21, 2014

Sparring in the Cyber Ring: Using Automated Pentesting to Build Resilience

Sparring in the Cyber Ring: Using Automated Pentesting to Build Resilience

Mar 26, 2025Penetration Testing / Vulnerability
"A boxer derives the greatest advantage from his sparring partner…" — Epictetus, 50–135 AD Hands up. Chin tucked. Knees bent. The bell rings, and both boxers meet in the center and circle. Red throws out three jabs, feints a fourth, and—BANG—lands a right hand on Blue down the center. This wasn't Blue's first day and despite his solid defense in front of the mirror, he feels the pressure. But something changed in the ring; the variety of punches, the feints, the intensity – it's nothing like his coach's simulations. Is my defense strong enough to withstand this? He wonders, do I even have a defense? His coach reassures him "If it weren't for all your practice, you wouldn't have defended those first jabs. You've got a defense—now you need to calibrate it. And that happens in the ring." Cybersecurity is no different. You can have your hands up—deploying the right architecture, policies, and security measures—but the smallest gap in your defense could let an attacker land a kn...
