Expert says CISA silently fixing bugs could be a problem

SCM feed for Latest

The Cybersecurity and Infrastructure Security Agency (CISA) has been updating software vulnerabilities related to ransomware without notifying cybersecurity defenders, as pointed out by Glenn Thorpe of GreyNoise. This lack of transparency could lead to missed ransomware intrusions, as defenders may not be aware of the vulnerabilities that have been patched. The updates affected numerous software vulnerabilities last year, raising concerns about the potential risks for organizations relying on these systems. The situation emphasizes the need for better communication between CISA and cybersecurity professionals to ensure that all parties are informed about critical updates that could impact security posture.
