removal by Gabriel E. Hall - - | Type: Ransomware

KEYPASS ransomware – a dangerous cryptovirus that infiltrates systems via fake software installers

Keypass ransomware virus
Keypass ransomware - a sneaky cryptovirus which enters the system without any notice.

KEYPASS ransomware is a dangerous cryptovirus which belongs to the same family as STOP ransomware. Once installed, it makes changes to the Windows Registry to gain boot persistence. The malware then uses AES-256 cipher to encrypt files and adds a .keypass extension. Additionally, virus connects to its C&C servers to receive the encryption key and make user's files useless without it. Victims are informed about this attack via the !!!KEYPASS_DECRYPTION_INFO!!!.txt ransom note that requires a $300 ransom in Bitcoin in exchange for the decryptor for the locked data. The victim receives 72 hours to pay this fee. For that, users need to contact cybercriminals using keypass@bitmessage.ch email address. Note that KEYPASS ransomware has nothing to do with the well-known KeePass password management software.

KeyPass ransomware was first discovered by Kaspersky Lab experts on the 8th of August,[1] and infection submissions came from over 20 countries across the globe, with Brazil and Vietnam being hit the most. As of now, security experts are not sure about how the virus spreads, but several users reported that it appeared after they installed the Windows hacking tool KMSpico, while others stated that no changes were made before the KeyPass infection occurred.

KeyPass ransomware comes with a hidden feature called “Manual control”. It can only be activated only by using a specific key combination that allows hackers to take manual control[2] of the virus, allowing them to modify victim's ID, file extension, encryption key, and several other preferences related to file encryption process, making the KeyPass virus much more dangerous.

Security experts also noticed that in the Command & Control server is not reachable or the infected device is not connected to the internet, the malware uses a hard-coded key, which makes KeyPass ransomware removal and file retrieval a much easier task.

However, if the computer is connected to the network, the KeyPass ransomware does not only encrypts your regular personal files like pictures, databases, documents and similar but instead only skips a few folders on the machine, allowing the system to boot properly. After the encryption process is complete, most of the files receive .keypass appendix, leaving the device in a complete mess.

The ransom note that is retrieved from C&C server after the file encryption states the following:

While Keypass authors demand $300 ransom, the payment type is not mentioned. However, hackers usually rely on digital currency (Bitcoin, Monero, Litecoin, etc.) for all the transactions. This way, money transfers remain anonymous and prevent the law enforcement from tracking and punishing scammers. 

Nevertheless, we do not recommend contacting cybercriminals, as the chance of retrieving the key is quite low. Additionally, it might encourage bad actors to improve the malware code and increase the number of infections. Thus, better take care of KeyPass ransomware removal using anti-malware software, such as Reimage or Plumbytes Anti-MalwareMalwarebytes Malwarebytes, and then recover your files from a backup.

Keypass virus
Keypass ransomware is spreading around the world. Victims were observed in more than 20 countries.

Unfortunately, the Keypass ransomware can also be used as a backdoor for other infections, such as banking trojans, and other malware forms[3]. We recommend you not to wait and get rid of the virus as soon as possible, as the infection chance increases the longer you wait.

Remember, your computer and data safety is in your own hands. Better prepare for such attacks in advance – keep important files safe and on a USB stick or an external HDD. If you are already infected with Keypass ransomware and have no backups ready, you could try third-party software that could help you to recover your data. See instructions below.

Keep your PC safe from ransomware by following safety tips

According to UdenVirus.dk specialists[4], ransomware usually has one main distribution source – spam emails. Cybercriminals take action and send numerous phishing messages to accidental users. Once received, such messages can be found in the Spam section (however, phishing emails might slip through the built-in scanners and get into your Inbox instead). If you encounter this type of content – better eliminate it permanently to avoid severe computer infections.

We advise increasing your PC safety by running an antivirus program[5] on your computer. If you do not already have one, you should consider downloading a trustworthy one. Such anti-malware software will keep your machine secured from various infections if kept up-to-date as required.
