Ransomware Is On The Rise, What Can Telcos Do About It?
FierceTelecom, Wednesday, June 28,2023
Ransomware attacks are becoming more sophisticated as threat actors turn to new tactics like ransomware-as-a-service (RaaS) and encryption-less extortion, according to a new Ransomware Report from Zscaler's ThreatLabz research group.
Zscaler CISO Deepen Desai told Fierce what telco operators can do to confront the growing threat landscape.
The Ransomware Report found that in the Zscaler cloud, ransomware attacks witnessed a nearly 40% increase from April 2022 to April of this year, signaling a growing threat to organizations worldwide. Payloads (the malicious code that is delivered and executed on a target system as part of a cyberattack) observed in the Zscaler sandbox surged 57.50%.
Since 2022, Zscaler's ThreatLabz has identified thefts of increasing size - reaching several terabytes of data -- as part of several successful ransomware attacks, which were then used to extort ransoms.
