Babuk Ransomware Decryptor Updated to Recover Files Infected
Hackers use ransomware to encrypt victims’ files and render them inaccessible until a ransom is paid. This forces the victims to pay a ransom to regain access to compromised systems and data.
This tactic leads to financial gains for the threat actors. While ransomware attacks can be conducted at scale and threat actors can target individuals, businesses, and organizations.
The Babuk ransomware decryptor has recently received an update from Avast cybersecurity researchers, Cisco Talos, and the Dutch Police to allow for the recovery of files infected with the most recent ransomware variant.
Compounding the problem are zero-day vulnerabilities like the MOVEit SQLi, Zimbra XSS, and 300+ such vulnerabilities that get discovered each month. Delays in fixing these vulnerabilities lead to compliance issues, these delay can be minimized with a unique feature on AppTrana that helps you to get “Zero vulnerability report” within 72 hours.
