TripleM ransomware removal instructions

What is TripleM?

First discovered by malware security researcher, Michael Gillespie, TripleM is a new variant of a ransomware-type virus called MMM. Once infiltrated, TripleM encrypts stored data using RSA-2048 cryptography, creating a copy of each encrypted file and appending two different extensions (".triple_m" and ".info") to them. For example, the original file "sample.jpg" is renamed to "sample.jpg.triple_m", and the copy renamed to "sample.jpg.info". From this point, using compromised data becomes impossible. Following successful encryption, TripleM creates an HTML file ("RESTORE_triple_m__FILES.html") and places a copy in each existing folder.

The new HTML file contains a message stating that files are encrypted and can only be restored with a unique key and decryption tool. Unfortunately, this information is accurate. As mentioned above, TripleM employs RSA-2048 - an asymmetric encryption algorithm. This cryptography generates two unique keys (public [encryption] and private [decryption]) for each victim. Decrypting files without the private key is impossible. Criminals hide the key on a remote server, allowing them to make ransom demands for its release. To receive the key and decryption tool, users are encouraged to pay a ransom of .25 Bitcoins. It is also stated that the cost will gradually increase - .5 BTC after one week and 1 BTC after three weeks. Currently, 1 Bitcoin is equivalent to ~ $15000. Four weeks after encryption, the key is permanently deleted and restoring files becomes impossible. Despite these threats and demands, cyber criminals cannot be trusted. Although the cost is ridiculously high, these people often ignore victims once payments are submitted. Therefore, paying will probably deliver no positive result. As well as losing thousands of dollars, victims will support cyber criminals' malicious businesses. We strongly advise you to ignore all requests to pay any ransoms or contact these people. Unfortunately, there are no tools capable of cracking RSA cryptography and restoring files compromised by TripleM. The only solution is to restore everything from a backup.

Research shows that all ransomware-type viruses are very similar. As with TripleM, malware such as MadBit, STOP, Tastylock, and Dangerous also encrypts data and makes ransom demands. Although these viruses are developed by different cyber criminals, in most cases the only major differences are cost of decryption and type of cryptography used. Unfortunately, most ransomware employs algorithms (e.g., AES, RSA, etc.) that generate unique decryption keys. Therefore, restoring files manually (without developers' help) is impossible unless the malware is not fully developed or has certain bugs/flaws (e.g., stores the key locally, it is hard-coded, or similar). Ransomware-type viruses are one of the main reasons why you should keep regular data backups, however, backup files must be stored on a remote server (such as Cloud) or external (unplugged) storage. If not, the malware encrypts them as well.

How did ransomware infect my computer?

Ransomware-type viruses are typically distributed using trojans, fake software update tools, unofficial software download sources (peer-to-peer [P2P] networks, free file hosting websites, freeware download websites), and spam emails (malicious attachments). Trojans work simply - they open "backdoors" for malware to infiltrate the system. Fake updaters infect the system by exploiting outdated software bugs/flaws. Third party software download sources proliferate malware by presenting it as legitimate software - users are tricked into downloading and installing malware. Infectious attachments typically come in the format of JavaScript files or MS Office documents. Once opened, these files stealthily download and install malware. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.

How to protect yourself from ransomware infections?

To prevent ransomware infections, be very cautious when browsing the Internet. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, bear in mind that criminals proliferate malware via fake updaters. Therefore, use an implemented update function or a tool provided by the official developer. Furthermore, download your software from official sources only and, preferably, using a direct download link (third party downloaders/installers also proliferate malware). Files received from suspicious email addresses should never be opened. These emails should be deleted without reading. The key to computer safety is caution.
