What is a .ZZZZZ file?
A .ZZZZZ file is a type of file that has been encrypted by a specific kind of harmful software known as Locky ransomware. This ransomware is a form of malware used by cybercriminals to hijack personal files on your computer. Originally, these files might have been documents, images, or other data types like .TXT or .PNG files. However, once affected by Locky ransomware, these files get encrypted using advanced encryption techniques, specifically AES-256 and RSA, making them inaccessible to the user.
The .ZZZZZ file extension became notably recognized in 2016 when the Locky ransomware was actively spreading. The way this ransomware typically reaches a computer is through deceptive methods such as spam emails. These emails might contain harmful attachments or links that, when opened, activate the ransomware on the computer. The ransomware then proceeds to encrypt files, rename them with the .ZZZZZ extension, and essentially lock the user out of their data.
After encrypting the files, the ransomware creates a ransom note in a .TXT file format. This note explains to the victim that their files have been encrypted and provides instructions on how to pay a ransom, usually demanded in Bitcoin, to get the decryption key needed to unlock the files.
Regarding opening .ZZZZZ files, it is important to note that these files cannot be directly opened or accessed due to their encrypted state. The primary method suggested for potentially restoring these files is through a system restore or by using backup copies of the files if available. It is highly discouraged to pay the ransom as it does not guarantee the recovery of the encrypted files and further encourages the cybercriminals.
In summary, .ZZZZZ files are encrypted files created by Locky ransomware, which locks users out of their data and demands a ransom to potentially restore access. The best approach to dealing with such files is to prevent infection in the first place by avoiding suspicious emails and using reliable antivirus software. If infected, seeking professional help from cybersecurity experts is advisable.
