The '.ttt File Extension' Ransomware is one of the many variants of the infamous TeslaCrypt, which has been active since early 2015. The '.ttt File Extension' Ransomware is distributed currently as TeslaCrypt 3.0. The '.ttt File Extension' Ransomware uses the '.ttt' file extension to identify files that have been encrypted using this ransomware threat. This newer version of TeslaCrypt is particularly threatening because it closes a loophole that allowed security researchers to recover the decryption key from an encrypted file, a weakness of previous versions of TeslaCrypt. If the '.ttt File Extension' Ransomware has infected your computer, PC security researchers strongly advise computer users to recover their files from a backup location. Prevention is the key to dealing with ransomware threats such as the '.ttt File Extension' Ransomware, both in the use of backups and strong security software. Since it is so difficult to recover the encrypted files (often impossible, in fact), computer users must be especially ready to prevent these kinds of attacks before they happen.
How the '.ttt File Extension' Ransomware Attacks a Computer
Like other ransomware, the '.ttt File Extension' Ransomware takes the victim's files after encrypting them using AES encryption. Once encrypted, these files cannot be decrypted without the decryption key. This is how most ransomware operates today. These attacks have increased in popularity, gotten more frequent with the rise of the 'Ransomware as a Service' (RaaS) industry. These enterprises offer ransomware to clients that may distribute them using other methods. These types of ransomware use the same basic approach, but may be customized to carry out different types of attacks or ask for different payment methods or amounts. The creators of these ransomware services may get a percentage of the revenue generated as part of their payment, creating an incentive for con artists to continue creating and distributing these threats.
The '.ttt File Extension' Ransomware attack is simple:
- The '.ttt File Extension' Ransomware scans the victim's hard drives for files matching the list of extensions the '.ttt File Extension' Ransomware targets.
- The '.ttt File Extension' Ransomware will encrypt all of these files using its encryption algorithm.
- The '.ttt File Extension' Ransomware sends the decryption key to its Command and Control server (since the key is not on the victim's computer, there is no way to extract it to decrypt the encrypted files).
- The '.ttt File Extension' Ransomware changes affected files' extension to '.ttt' and drops various text or HTML files with payment instructions. The '.ttt File Extension' Ransomware may change the victim's Desktop image to a ransom note with some variant of the following message:
Your personal files are encrypted!
Your files have been safely encrypted on this PC: photos, videos, documents, etc. Click "Show Encrypted Files" button to view a complete list on encrypted files, and you can personally verify this.
Encryption was produced using a unique public key RSA-2048 generated for this computer. To decrypt files you need to obtain the private key.
Prevention is the Best Measure Against the '.ttt File Extension' Ransomware and Other Ransomware
When dealing with a '.ttt File Extension' Ransomware attack, one of the priorities is to ensure that no traces of the '.ttt File Extension' Ransomware remain on the infected computer. Otherwise, the victim's files may be encrypted again, after the '.ttt File Extension' Ransomware's uncompleted remotion. Because of this, the best way to deal with these threats is to wipe the affected drives and restore the files from a backup location (such as the cloud or an external memory device). Malware researchers advise against paying the '.ttt File Extension' Ransomware ransom. Apart from the fact that computer users have no guarantee that the people responsible for the '.ttt File Extension' Ransomware will honor their word, paying these types of ransoms encourages con artists and allows them to continue to finance these attacks.
