Hmmmmm ransomware – cryptovirus that doubles ransom amount after 48 hours if victims fail to contact the cybercriminals
Hmmmmm ransomware is a cryptovirus virus that encrypts all non-system files on a targeted computer and demands a ransom to be made in Bitcoins to regain access to the data. This virus belongs to the relatively new VoidCrypt ransomware family that has been first spotted in April of 2020.
The virus encrypts all personal files, like pics, videos, documents, archives, backups, and so on. During this process, all those files are renamed by appending the criminal's email address (in brackets), appointed victim ID (in brackets), and .hmmmmm extension to them.
Files are encrypted using a combination of AES-256 and RSA-2048 coding algorithms. Afterwards, .hmmmmm file virus generates ransom notes, titled !INFO.HTA in all folders that contain locked files, just like it's previous versions in Decme, Shiton, and others.
| name | Hmmmmm ransomware, Hmmmmm virus files |
|---|---|
| type | Ransomware |
| family | VoidCrypt ransomware |
| ransom note | !INFO.HTA |
| Appended file extension | All non-system files are appended with 1.[ASer51a0@mailfence.com] 2.[appointed unique victim ID] 3. .hmmmmm extension |
| Criminal contact details | Victims can contact the criminals by writing an email to aser51a0@mailfence.com or windows358@protonmail.com |
| MAlware removal | Ransomware, like all malware, should be removed immediately by using a professional anti-malware software |
| System repair | All malware is capable of doing extensive damage to system files and settings, so after ransomware elimination, a system tune-up should do be done with a system repair tool like the FortectIntego app |
Unlike ransom notes of Nobu, Hmmmmm ransomware notes are short and no that informative. First, the virus developers state that all files have been locked with the highest security cryptography algorithms and that the only way to decrypt the data is by purchasing their decryption tool.
The ransom amount isn't specified, but the cybercriminals threaten that the price will be doubled after 48 hours. However, it's not clear when the timer starts, from the infection or from sending the first email. What's obvious is that the hackers would like to get paid in cryptocurrency Bitcoins.
To reassure the victims that they have the necessary decryption tool, Hmmmmm ransomware makers offer to send them a few files from the encrypted machines for a free decryption using any of two given emails – aser51a0@mailfence.com or windows358@protonmail.com. Also, a user ID is provided, the same one as in one of the extensions of the encrypted files.
Victims of such cyberattacks should never contact the perpetrators. In no way should they pay the ransom because that encourages the hackers to increase their attacks and search for new, more efficient ways to spread their creations. Remove Hmmmmm ransomware immediately with anti-malware software like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes.
When you're finished with Hmmmmm ransomware removal, a system repair is in order. Experts [1] recommend using the FortectIntego tool to locate and correct any irregularities that the cryptovirus virus might have caused when it was in your computer system.
