Over the past week, Microsoft Exchange Mail Servers have been under attack by a new ransomware family tracked under the name DearCry. The criminals behind the attack campaign are exploiting four new vulnerabilities that Microsoft has already patched – however, users who have failed to update their software may still be at risk of having their systems compromised. The DearCry Ransomware is in no way associated with the WannaCry Ransomware – its creators are simply piggybacking on the popularity of the infamous ransomware family.
The DearCry Ransomware uses a flawless file-locking mechanism, and it targets a wide range of file extensions to inflict maximum damage. It encrypts the contents of the file, and also adds the header 'DEARCRY!' Just like other ransomware, it uses a custom file extension to modify the names of damaged files – 'CRYPT.'
After completing its attack, the DearCry Ransomware drops the ransom note 'readme.txt' on the desktop. It tells the victim to contact email@example.com or firstname.lastname@example.org for assistance. As expected, contacting the attackers is only the start – they will then extort their victim for money by promising to give them access to a decryptor, but only if they agree to pay a ransom fee.
Unfortunately, free decryption is impossible, and the only reliable way to recover the lost files is to recover them via a backup. If a backup is not available, users can explore alternative data recovery options.
