Annual ThreatLabz Ransomware Report Tracks Trends and Impacts of Ransomware Attacks Including Encryption-less Extortion and Growth of Ransomware-as-a-Service
Key Findings:
-
Ransomware impact is felt most acutely in the United States, which was the target for nearly half of ransomware campaigns over the last 12 months.
-
Organizations in the arts, entertainment, and recreation industry experienced the largest surge in ransomware attacks, with a growth rate over 430%.
-
The manufacturing sector remains the most targeted industry vertical, accounting for nearly 15% of total ransomware attacks. It is followed by the services sector, which experienced approximately 12% of the total quantity of ransomware attacks last year.
-
25 new ransomware families were identified as using double extortion or encryption-less extortion attacks this year.
SAN JOSE, Calif., June 28, 2023 (GLOBE NEWSWIRE) — Zscaler, Inc. (NASDAQ: ZS), the leader in cloud security, today announced the release of the 2023 ThreatLabz Ransomware Report.

Since April 2022, ThreatLabz has identified thefts of several terabytes of data as part of several successful ransomware attacks, which were then used to extort ransoms.

Organizations must move away from using legacy point products and instead migrate to a fully integrated zero trust platform that minimizes their attack surface, prevents compromise, reduces the blast radius in the event of a successful attack, and prevents data exfiltration.”
The evolution of ransomware is characterized by the inverse relationship between attack sophistication and barrier of entry for new…
