Dharma Ransomware – How Does It Replicate
Users on security forums report that the malware has been infecting multiple computers on office networks, suggesting that the virus may not only be spread to home computers, but also attack organizations as well. This can be done in a number of ways:
- A “dropped” flash drive that may directly cause the infection after being inserted in one office computer.
- A worm-like features that aim to replicate the malware automatically from one system to another in a home or office network.
- Massive spam campaigns that target the office network or multiple different computers with phishing e-mails and malicious e-mail attachments added to them.
Whatever the case of Dharma ransomware may be, the virus may be spread massively and may be a variant that has come up from either an open source project or someone may have purchased it’s source code in the dark net.
The Dharma ransomware was also undetected by most conventional antivirus programs, suggesting that the virus may use a sophisticated obfuscator that allows execution without detection.
More Information about Dharma Ransomware
As soon as the user is on the malicious URL or opens a malicious attachment that is carrying the infection vector of Dharma ransomware, the ransomware is automatically executed and it begins to immediately inject commands in the legitimate Windows processes, like svchost.exe and explorer.exe. The ransomware may initially delete any shadow volume copies or other backups on the computer, running the vssadmin command in concealed mode:
After deleting all the file history, the Dharma virus may begin to add custom registry values with data in the Run and RunOnce 3Windows Registry subkeys. This data is usually configured with settings to make the malicious files of the virus run and begin encrypting:
- Audio files.
- Video files.
- Database types of files.
- Various files associated with often used programs, like VMware, Photoshop, etc.
- Microsoft Office files.
- Adobe Reader .PDF’s.
After the virus completes the encryption, during which the computer’s explorer.exe process may enter a ‘Not Responding’ state, it appends e-mail address of the cyber-criminals and the .dharma file extension to the encrypted files, which can no longer be opened. Then a unique decryption key is generated which is believed to be sent out to the command and control servers of the cyber-criminals. The encrypted files look like the picture below after the process is complete:
