How was the ransomware attack initially detected?
The ransomware attack was first detected by the Managed Detection and Response (MDR) for endpoint using a detection rule that had been deployed several months earlier. This rule specifically looked for the BestCrypt utility being copied onto machines in a suspicious manner, which indicated the activity of a known ransomware actor.
What actions were taken during the incident response?
Once the attack was confirmed, the incident was escalated to the incident handling team. They quickly scoped the intrusion, identifying the adversary's activity across more than 250 workstations and servers. The team blocked the BestCrypt executable across all endpoints and isolated impacted systems to maintain connectivity while denying the attacker access. They also communicated with the customer to keep them informed throughout the process.
How did the team manage the BitLocker encryption issue?
The team discovered that the attackers had configured BitLocker in a way that would complicate recovery after a restart. However, they managed to cancel the restart command that would have initiated the encryption, effectively reversing the BitLocker encryption process. This timely intervention allowed them to prevent significant data loss across the impacted hosts.
