 Tricks used for ransomware distribution

To infect systems with this malware, its developers spread this ransomware actively through phishing. This is the most common method considered for the delivery of this Trojan virus by infected email messages. The cyber scammers use nasty spam campaigns to spread fraudulent emails with attached malware and unfortunately, the users often fall for their tricks.

  1. If you, are the only recipient of such an email from some unknown sender, company or institution, carefully investigate it.
  2. Think about whether you were expecting any such an email in the first place, if you have no idea why it has reached your email – it might be that you are being targeted by extortionists.
  3. Stay away from any unreliable attachments that might be added to the email and delete it immediately. Otherwise, Dharma can sneak in its malicious payload with some fake plane ticket, speeding ticket or any other documents that might look convincing enough to be taken for granted.

How the Dharma Ransomware Infection Works in your computer?

PC security analysts believes that Dharma Ransomware is one of the many variants of the infamous Crysis Ransomware family, which was accountable for frequent attacks since Summer of 2016. The Dharma Ransomware and its variants were spread through corrupted email attachments that exploit vulnerabilities in macros on the victim's computer. The Dharma Ransomware infection is honestly characteristic of these encryption ransomware attacks in the recent past. The Dharma Ransomware uses the same old method of AES-256 encryption to govern over the victim's data, preventing computer users from accessing their saved files. The Dharma Ransomware attacks will aim the following directories:

 

%UserProfile%\Desktop

%UserProfile%\Downloads

%UserProfile%\Documents

%UserProfile%\Pictures

%UserProfile%\Music

%UserProfile%\Videos

Post the infection in the computer, Dharma’s text file consists of a very short message stating that the victim's computer is unprotected, and that cyber hacker can solve this problem and restore the encrypted files. To restore the locked files, victims must contact Dharma's developers via an email address provided (bitcoin143@india.com). Further instructions are then provided. As mentioned, Dharma encrypts files using asymmetric algorithm and, therefore, public (encryption) and private (decryption) keys are generated during the process. The private key is stored on a remote server controlled by the its creator. Decryption without this key is not possible and a ransom demand is made to receive it. The cost is currently unknown, however, cyber pundits responsible for the development of ransomware usually demand $500-$1000 Bitcoins. Be careful, because most of the times, these cyber criminals often ignore victims, although the payments made. Therefore, you should never attempt to contact these people or pay any ransom. There is a high probability that you can be a victim of this scam. Manually restoring files encrypted by Dharma is currently impossible (there are no tools capable of performing this function). Therefore, the only resolution is to create your files/system from a backup.
