CISA — CL0P ransomware exploits MOVEit vulnerability

The MOVEit case showed how a vulnerability in a tool used by many organizations can turn into a large-scale incident.

The problem was not only technical: it also affected suppliers, third parties, personal data, incident communication and business continuity.

Key idea: A company can be affected even if the failure is with a supplier. That is why third-party management and incident response are an essential part of ISO 27001, ENS and NIS2.

What happened on a practical level

According to CISA, the CL0P group exploited CVE-2023-34362 in MOVEit Transfer. This type of case demonstrates that patching quickly, monitoring external exposure, and having up-to-date inventory are not optional.
