Case Study: Telecommunications company servicing millions of customers contains Black Basta ransomware with Palo Alto Networks Unit 42

Telecommunications Company Servicing Millions of Customers restores operations in 30 days with Palo Alto Networks after Black Basta attack

A telecommunications company servicing millions of customers was hit with a severe Black Basta ransomware attack that encrypted tens of thousands of systems, halted half of its business operations, and exfiltrated sensitive data. The company engaged Palo Alto Networks and its Unit 42 Incident Response team to contain the threat, eradicate the attacker, and restore operations.

Palo Alto Networks deployed its Cortex XDR platform across the environment for containment and 24/7 monitoring. Unit 42 experts identified the attack vector, negotiated an 80% reduction in the ransom demand, and obtained decryption keys. The team fully contained the threat, restored critical operations, and implemented additional firewalls and Prisma Access to fortify security, ensuring full visibility and protection across over 30,000 endpoints.
