The Hmmmmm virus was originally discovered by virus analyst Tomas Meskauskas, and belongs to the ransomware type infection. This ransomware encrypts all user’s data on the PC (photos, documents, excel tables, music, videos, etc), adds its specific extension to every file, and creates the !INFO.HTA files in every folder which contains encrypted files.
What is “Hmmmmm”?
☝️ Hmmmmm can be correctly identify as a ransomware-type infection.
After the encryption process files will be renamed according to the pattern hmmmmm, which is laid in ransomware. Your photo, named an example “me.jpg” will be altered to “me.jpg.[ASer51a0@mailfence.com][ZVNC2IBGP8WFE6L].hmmmmm” after the encryption.
!INFO.HTA file, which can be found in every folder that contains the encrypted files, is a ransom money note. Inside of it, you can find information about ways of contacting Hmmmmm ransomware developers, and some other info. Inside of the ransom note, there is usually an instruction saying about purchasing the decryption tool. This decryption tool is created by ransomware developers, and can be obtained through the email, contacting aser51a0@mailfence.com and windows358@protonmail.com.
Here is a summary for the Hmmmmm:
| Extension | .hmmmmm |
| Ransomware note | !INFO.HTA |
| Contact | aser51a0@mailfence.com and windows358@protonmail.com |
| Detection | Virus:Win32/Neshta.B, MSIL/Bladabindi.BA, Win32/GenKryptik.EXOU |
| Symptoms | Your files (photos, videos, documents) have a .hmmmmm extension and you can’t open it. |
| Fix Tool | See If Your System Has Been Affected by Hmmmmm virus |

How did I get Hmmmmm ransomware on my computer?
That was a huge number of different ways of ransomware injection.
Ransomware injection scheme
As it was stated, ransomware distributors are not pretty innovative in distributing ways. The biggest share of . virus infiltrations is against email spamming. Victim gets an email which looks similar to a notification from the delivery company, invoice from the automobile lending firm, et cetera. However, the sender’s address doesn’t look acquainted: normally, it is a bundle of randomly-picked numbers and letters, like “jawlnciacm3124@aol.com”. Organizations generally use addresses that are corresponding to their own labels, so the use of such a weird e-mail address must raise suspicion. However, as the practical incidents show, people typically do not look at the sender’s address, clicking the web links or opening the attached files with no doubts. Hmmmmm ransomware is stashed in this attachment, or in the document which will be downloaded after following the link.
The second (by success) manner of ransomware distribution is trojan viruses. In the last several years, trojans became all-in-one viruses: one malware may include spyware, backdoor, keylogger and downloader; the last one is used to recover the viruses, if they are deleted by the user, as well as to download new and new malware. Ransomware may be included to first trojan packaging, and also downloaded later by malware downloader. It is extremely difficult to estimate, when the ransomware will show itself.
How to remove Hmmmmm virus?
In addition to encode a victim’s files, the Hmmmmm virus has also started to install the Azorult Spyware on PC to steal account credentials, cryptocurrency wallets, desktop files, and more.
To ensure the user that ransomware distributors really have the decryption tool, they may offer to decrypt several encrypted files. And they are the single owners of this decryption program: Hmmmmm ransomware is a completely new type, so there is no legit program from anti-malware vendors, which can decrypt your files. But such a situation is in momentum: decryption tools are updating every month.
However, paying the ransom is a bad decision, too. There is no guarantee that Hmmmmm ransomware developers will send you the decryption tool and a proper decryption key. And there are a lot of cases when ransomware distributors deceived their victims, sending the wrong key or even nothing. In the majority of cases, there is a way to recover your files for free. Search for available backups, and restore your system using it. Of course, there is a chance that the backup you found is too old, and does not contain a lot of files you need. But, at least you will be sure that there is no malware in your system. However, to ensure that there are no malicious programs in your system after the backup, you need to scan your PC with anti-malware software.
Hmmmmm ransomware is not unique. There are more ransomware of this type: Doppelpaymer, Esexz, Nsemad. These examples of ransomware act in a similar way: encrypting your files, adding a specific extension, and leaving a great number of ransom money notes in every folder. But there are two things which make difference between these ransomware – cryptography algorithm, which is used for file encryption, and ransom amount. In some cases, victims are able to decrypt their files without any payments, just using free solutions produced by several anti-malware vendors, or even with the decryption tool which is offered by ransomware creators. The last scenario is possible when ransomware distributors have typed your decryption key inside of a ransom money note. However, as you can already guess, such luck is a very rare thing. Ransomware is created for money gaining, not for jokes or scaring.

Frequently Asked Questions
No way. These files are encrypted by Hmmmmm ransomware. The contents of .hmmmmm files are not available until they are decrypted.
If your data remained in the .hmmmmm files are very valuable, then most likely you made a backup copy.
If not, then you can try to restore them through the system function – Restore Point. All other methods will require patience.
Of course not. Your encrypted files do not pose a threat to the computer. What happened has already happened.
You need GridinSoft Anti-Malware to remove active system infections. The virus that encrypted your files is most likely still active and periodically runs a test for the ability to encrypt even more files. Also, these viruses install keyloggers and backdoors for further malicious actions (for example, theft of passwords, credit cards) often.
In this situation, you need to prepare the memory stick with a pre-installed Trojan Killer.
You can try to find a copy of an original file that was encrypted:
- Files you downloaded from the Internet that were encrypted and you can download again to get the original.
- Pictures that you shared with family and friends that they can just send back to you.
- Photos that you uploaded on social media or cloud services like Carbonite, OneDrive, iDrive, Google Drive, etc)
- Attachments in emails you sent or received and saved.
- Files on an older computer, flash drive, external drive, camera memory card, or iPhone where you transferred data to the infected computer.
Also, you can contact the following government fraud and scam sites to report this attack:
- In the United States: On Guard Online;
- In Canada: Canadian Anti-Fraud Centre;
- In the United Kingdom: Action Fraud;
- In Australia: SCAMwatch;
- In New Zealand: Consumer Affairs Scams;
- In France: Agence nationale de la sécurité des systèmes d’information;
- In Germany: Bundesamt für Sicherheit in der Informationstechnik;
- In Ireland: An Garda Síochána;
To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
How сan I avoid ransomware attack?
Hmmmmm ransomware doesn’t have a superpower.
You can easily protect yourself from its injection in several easy steps :
- Ignore all emails from unknown mailboxes with a strange unknown address, or with content that has likely no connection to something you are waiting for (can you win in a lottery without taking part in it?). If the email subject is likely something you are waiting for, check carefully all elements of the suspicious letter. A fake email will surely contain a mistake.
- Do not use cracked or untrusted programs. Trojans are often distributed as a part of cracked software, possibly under the guise of “patch” which prevents the license check. But untrusted programs are very hard to distinguish from trustworthy software, because trojans may also have the functionality you need. You can try to find information about this program on the anti-malware forums, but the best solution is not to use such programs.
- And to be sure about the safety of the files you downloaded, use GridinSoft Anti-Malware. This program will surely be a perfect shield for your personal computer.
