It can also happen after opening files downloaded from unreliable sources such as Peer-to-Peer networks, third-party downloaders, unofficial pages, free file hosting pages, etc.
How did ransomware infect my computer?Ĭomputers get infected after malicious attachments or files downloaded from websites in emails received from threat actors are opened.
More ransomware examples are Vlff, Pandora, Report. The most common differences between ransomware attacks are the algorithms used to encrypt files, extensions appended to filenames, and prices of decryption tools. Typically, victims can avoid data and monetary loss if they have their files backed up (have a copy of files stored on a remote server, unplugged storage device, or somewhere else). Ransomware in generalĬybercriminals use ransomware to encrypt files and force victims to pay for their decryption. Therefore, it is strongly recommended to eliminate ransomware from infected computers as soon as possible. Paying it does not guarantee that cybercriminals will cooperate (send a decryption tool).Īnother important detail about ransomware is that it can spread itself over a local network and (or) encrypt files stored after the attack. Free data recovery is possible when victims have a data backup or a working third-party decryption tool downloaded from the Internet. Usually, files cannot be decrypted without tools purchased from the attackers. It also mentions that victims can have a few files decrypted for free. It instructs to send the provided personal ID to or to get further instructions (payment information). Screenshot of files encrypted by this ransomware:Īvast's ransom note informs victims that files cannot be decrypted without the right tool. An example of how this ransomware renames files: it changes " 1.jpg" to " 1.jpg.avast", " 2.png" to " 2.png.avast", and so forth. avast") to filenames, and drops the " RECOVERY INFORMATION.txt" file containing a ransom note. We analyzed the Avast ransomware and found that it encrypts files, appends its extension (". Cybercriminals behind the Avast ransomware probably chose this name to avenge the Avast company for creating a decryption tool. Avast's developers have created a decryption tool for other variants of the TargetCompany ransomware. Our team has discovered a TargetCompany ransomware variant called Avast (named after Avast cybersecurity software company) while examining the samples submitted to VirusTotal.
