How Did I Get .him0m Ransomware

In case you have been affected by this nasty virus, there are several possible ways you could have activated its malicious files. The main method of such ransomware spreading across computers is via spam mail. Spam emails come in all shapes and sizes, and cyber criminals may even use websites such as PayPal or eBay to fabricate false messages and get users to download a malicious attachment to the email or embedded as a drive-by-download in an external URL in the email message itself.

There are also other forms of this ransomware spreading. Basically, anywhere where you may have found and clicked on suspicious web links may have been the malicious one. We are talking about chat spam, visiting suspicious and risky sites as well as directly letting someone have physical access to your computer.

.Him0m Ransomware – More about It

Once activated on the user PC the ransomware is reported to use a win32 / Injector.COMJ – A trojan horse that is most likely created to deliver the ransomware`s payload on the computer. After the payload is delivered, the ransomware may begin to scan the user PC for files to encrypt.

Similar to TeslaCrypt Ransomware, the cyber-threat then may encrypt .docx, .jpg, .pdf, .xls, .mp3 and other file formats used by Microsoft Office, Adobe Reader and other useful software. In the meantime, the ransomware has been reported to have countermeasures against certain notorious anti-malware software such as Malwarebytes Anti-Malware. Affected users report a ”Runtime Error” given while trying to launch MBAM to scan and remove the malware. The files are encrypted with the .him0m extension and upon opening Windows displays a ”File Corrupt” type of message.

After the user`s files have been successfully encrypted, they look like the following:


After encrypting the files, the ransomware may also encrypt the names of the files, concealing the file name from the user. Furthermore, after the encryption process is complete, the ransomware leaves the following ransom note:


Analyzing the note, this is one of the cases where instead of using Tor networking, the cyber criminals have preferred to use an anonymous p2p chat called Bitmessage. Given the seriousness of this ransom note, they are not willing to even negotiate the ransom amount. Despite the fact that according to the note, the Ransomware may use a unique key featuring algorithm, like the RSA, the actual algorithm may be different. No matter how important your files may be, we strongly advise against paying the ransom money because of the following reasons:

  • The cyber-criminals may not provide you with decryption keys.
  • You fund them to complicate their malware and initiate spam campaigns to spread it further.

Without going into much detail, in case you have been affected from such ransomware, it is imperative to immediately disconnect the computer from your home or office network since such malware usually may have some worm features that may allow it to spread to other computers in the network as well.
