Mr.Dark101 Ransomware Removal

Overview of Mr.Dark101 Ransomware

The Mr.Dark101 ransomware is a variant of the Chaos ransomware family, a notorious lineage of cryptoviruses. Upon infecting a system, this ransomware encrypts files and alters their names by appending a unique four-character random extension. For instance, a file named “document.pdf” may be transformed into “document.pdf.abcd.” Beyond encryption, Mr.Dark101 modifies the victim’s desktop wallpaper and leaves a ransom note in a text file titled “read_it.txt.”

Like most ransomware attacks, the note includes instructions for victims to pay a ransom in exchange for decryption. However, paying the ransom is strongly discouraged, as there are no guarantees that attackers will provide the necessary decryption keys.

How Mr.Dark101 Ransomware Infects Systems

Mr.Dark101 ransomware primarily infiltrates systems through:

1. Spam Emails and Malicious Attachments: Attackers often distribute ransomware payloads via email campaigns. These emails may contain malicious links or attachments disguised as legitimate documents.
2. File-Sharing Platforms and Torrents: Users who download software or files from unreliable sources risk exposing their systems to ransomware infections.
3. Social Media Links: Cybercriminals may use social engineering tactics on social media to lure users into downloading infected files.
4. Bundled Freeware: Some freeware programs include hidden malicious scripts that execute upon installation.

Once inside the system, Mr.Dark101 executes a payload dropper to initiate the encryption process. It may also erase Shadow Volume Copies using the following command:

vssadmin.exe delete shadows /all /Quiet

This command prevents users from restoring files through Windows’ built-in recovery mechanisms.
