What is HrHr ransomware? And how does it implement its attack?

HrHr ransomware is a new crypto-malware designed to lock files in infected computers and demands a ransom to its victims. This ransomware threat was recently reported to be causing problems in the cyber community as it affects many computer users.
Once it is able to invade a targeted PC, HrHr ransomware will start to search the entire drive of the system looking for certain files to lock. Based on the analysis done by security experts, HrHr ransomware encrypts files that have these extensions:
After it finds the files with the extensions listed above, HrHr ransomware will encrypt them using a strong encryption algorithm and append the .hrhr extension on each one of the files. Following file encryption, HrHr ransomware will drop the help.txt file containing the following ransom note:
“Hello. Your files have been encrypted.
For help, write to this e-mail:
[email protected]
Attach to the letter 1-2 files (no more than 3 MB) and your personal key.
If within 24 hours you have not received a response, you need to follow the following instructions:

  1. a) Download and install TOR browser: https://www.torproject.org/download/download-easy.html.en
  2. b) From the TOR browser, follow the link: torbox3uiot6wchz.onion
  3. c) Register your e-mail (Sign Up)
  4. d) Write us on e-mail:

[email protected]
ATTENTION: e-mail ([email protected]) accepts emails, only with e-mail registered in the TOR browser at torbox3uiot6wchz.onion
Your personal key:”
In addition to the encryption, HrHr ransomware may also drop additional malicious files to modify some system settings in the infected system.
Despite the current state of your important files, paying the ransom is still not recommended. Just know that cybercriminals are called cyber criminals for a reason – they can’t and will never be trusted. So it’s best to try other recovery options rather than succumb to these crooks’ demands.
How does HrHr ransomware disseminate its malicious payload?
HrHr ransomware disseminates its malicious payload using spam emails. The email containing the malicious payload aims to convince users into not only installing the Tor browser but also using an encrypted email service called “TorBox which is only available on the Onion network. So the next time you open any suspicious emails, you should know better and delete the email right away. One of the telltale signs that the email is actually a malware-laden one is that the contents of the email will contain some file with the double extension, i.e. invoice.pdf.exe, and its message full of grammatical errors will convince you to download the attachment.
