Ransomware attackers are now utilizing Windows EFS (Encrypting File System) to further encrypt files on the victims system, making it harder for users to recover their data without paying the ransom.
This new tactic significantly increases the difficulty of recovering encrypted files without the decryption key, adding another layer of protection for attackers and potentially increasing the likelihood of victims paying the ransom.
It is crucial for users to regularly back up their data and ensure the backups are stored securely in order to mitigate the impact of a ransomware attack. Additionally, staying vigilant against phishing emails and suspicious downloads can help prevent ransomware infections.
Ransomware attackers can use Windows EFS to encrypt files with a users key, making it more challenging for victims to recover their data without paying the ransom.
Decrypting files encrypted with Windows EFS without the proper decryption key can be extremely difficult, if not impossible, for victims of ransomware attacks.
Unfortunately, without access to the decryption key used by the ransomware attacker, recovering data encrypted using Windows EFS can be nearly impossible, making it essential for users to maintain secure backups of their important files.
