What is Hmmmmm ransomware?

Hmmmmm ransomware – cryptovirus that doubles ransom amount after 48 hours if victims fail to contact the cybercriminals

Hmmmmm ransomwareHmmmmm ransomware is a data-locking computer infection that asks for a ransom within the !INFO.HTA file

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.

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 – or 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 SpyHunter 5Combo Cleaner or Malwarebytes.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
