Hermes virus leads to Lazarus Group hackers

The sample of Hermes note

Hermes virus hardly has any relations with the fashion world, but it certainly has a lot in common with cyber crime[1] world. It refers to the crypto-malware [2]. Since its appearance, two more versions surfaced.

Interestingly, specialists have unraveled evidence suggesting that the malware might have originated from North Korea. The infamous hackers' group Lazarus[3], associated with this country, is said to have exploited the ransomware to hide tracks of the attack on Far Eastern International Bank (FEIB) located in Taiwan.

If hijack process is successful, it encodes data on the computer using a RSA-2048[4] algorithm – the process lasts only a few minutes. As a rseult, all affected data is now marked with .hermes file extension.

However, many computer users are used to computer slowdowns and do not pay attention to them unless they last for a very long time. Once the virus finished its dirty work, it puts some information in a .html file called DECRYPT_INFORMATION.html and also creates a UNIQUE_ID_DO_NOT_REMOVE file on the desktop.

Fraudsters say that the victim can test the decryption tool by sending three files as well as unique victim’s ID to criminals via email provided in the ransom note – x2486@india.com. If you have been attacked by this particular Hermes ransomware, please do not panic and wait until malware analysts analyze the sample of this virus.

Although it happens rarely, the virus might contain bugs or flaws that could allow researchers to create an antidote for it. Until then, we advise you to remove Hermes virus. The easiest way to do it is to use the anti-malware program, for instance, Reimage or Malwarebytes Anti Malware. Please find comprehensive Hermes removal guidelines below the article.

Luckily, it seems that a decrypter for Hermes ransomware is about to show up very soon. A researcher Fabian Wosar analyzed a sample of Hermes virus and showed in a live video how he did that.

It turns out that this ransomware has a flaw that allows to find out what the decryption key is, based on the encryption key. However, the decryptor has to be polished and prepared for usage, therefore we cannot provide a link to download this tool yet. However, you should not lose hope to recover your files, so please keep up with the news and most importantly, do not pay the ransom. 

Other variations

Hermes 2.0 ransomware was released in April. It employs RSA-2048 cipher to encode data. After the process is finished, it launches DECRYPT_INFORMATION.html file which displays the message that all users data has been encoded. In order to retrieve the files, they are urged to pay the ransom in bitcoins and acquire Hermes 2.0 decryptor software. It also provides two single-use email addresses for victims in case they encounter technical difficulties. This version deletes shadow volume copies.

Hermes 2.1 ransomware continues the tradition of deleting the latter copies. The ransom note is identical to the previous version except the title now mentions “Hermes 2.1 ransomware.” It also drops the file named the same way as the former version – UNIQUE_ID_DO_NOT_REMOVE file which contains victim's ID.

This version also provides two newly generated email addresses: BM-2cTSTDcCD5cNqQ5Ugx4US7momFtBynwdgJ@bitmessage.ch and BM-2cT72URgs1AWGV6Wy6KBu2yuj3ychN5vxC@bitmessage.ch. This latest version also includes a code launching the mp3 file which plays Vivaldi's Spring composition.

Ways to prevent ransomware assault

Ransomware viruses are spread using a number of techniques such as malvertising, spam emails, social engineering, pirated software bundles and so on[5]. You can get the virus after opening an infected email attachment, link sent by an unknown person or even your friend on social media sites, or after installing a software crack.

Scammers find more and more ways to deceive victims on a daily basis, and it can be hard to keep up with the latest malware distribution trends all time.

To avoid ransomware, we simply advise you to stay away from suspicious content online[6] and protect your PC with proper security tools such as anti-malware and antivirus. The most important thing is to get yourself covered in time and create some data backups prior to malware infection.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Hermes from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files have .hermes extensions now, you probably cannot open them. Sadly, they can only be reverted to their initial state with a help of decryption key, but if you do not have it, you will need to use your data backups to recreate lost data. If you do not have data backup, follow these instructions.

If your files are encrypted by Hermes, you can use several methods to restore them:

Run Data Recovery software

Data Recovery Pro is a recommended tool when it comes to data recovery. You might want to install and run this tool to try and restore corrupted files. 

Windows Previous Versions

If you created a system restore point in the past, you are lucky, because now you will be able to restore some files without paying the ransom. Please, follow these easy steps.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Hermes decryptor

Researchers are currently working on Hermes decryptor and we believe that they will shortly release it for a public use. Be patient! We will insert a link here as soon as it becomes available.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Hermes and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
