The CISO Signal | INSIDE CNA's $40M BITCOIN RANSOM | The Hack That Changed Cybersecurity - EP 4
In this episode of The CISO Signal, we go deep inside the cyberattack that shook the financial world.
Join us as we unravel the haunting details of the 2021 ransomware attack on CNA Financial, which resulted in a record-breaking $40 million ransom payment in Bitcoin.
This wasn't just another breach. This was a black swan event cloaked in silence, executed by a mysterious threat actor known as Phoenix. They slid past defenses, encrypted over 15,000 devices, and vanished with a payday big enough to fund a small nation-state.
How did one of the largest U.S. insurers, an industry built on managing risk become the ultimate risk?
