Vulnerability / Data Recovery
Cybersecurity researchers have uncovered an "implementation vulnerability" that has made it possible to reconstruct encryption keys and decrypt data locked by Rhysida ransomware. The findings were published last week by a group of researchers from Kookmin University and the Korea Internet and Security Agency (KISA). "Through a comprehensive analysis of Rhysida Ransomware, we identified an implementation vulnerability, enabling us to regenerate the encryption key used by the malware," the researchers said . The development marks the first successful decryption of the ransomware strain, which first made its appearance in May 2023. A recovery tool is being distributed through KISA. The study is also the latest to achieve data decryption by exploiting implementation vulnerabilities in ransomware, after Magniber v2 , Ragnar Locker, Avaddon , and Hive . Rhysida , which is known to share overlaps with another ransomware crew called Vice Society, lever...
