Trojan.ArchiveLock Image
The ArchiveLock Trojan is a file encryptor that has been used in attacks against computer users located mainly in Spain and France. However, it is highly likely that attacks involving the ArchiveLock Trojan will spread to other countries, particularly in the European Union. The ArchiveLock Trojan is designed to prevent computer users from gaining access to their files, using a threatening ransom message after holding hostage the contents of the victim's hard drive. The ArchiveLock Trojan demands the staggeringly high amount of $5,000 USD in order to decrypt the victim's files. Security experts strongly counsel PC users against spending this amount; your files can be recovered without having to cave in to the people responsible for the ArchiveLock Trojan attack
The ArchiveLock Trojan Target the 'Big Books' Accounts
The ArchiveLock Trojan is mainly being distributed through brute force attacks specifically targeting the RDP protocol. Apparently, criminals are not casting a wide net but are instead targeting computers of individuals with large bank accounts or associated with businesses that have higher cash flow and potential earning. Once the ArchiveLock Trojan manages to break through the victim's computer's defenses, its attack is not complicated. The ArchiveLock Trojan attack may have the following steps:
- First the ArchiveLock Trojan will make a copy of WinRAR on the infected computer. It is preeminent to know that it is the console version of WinRAR, meaning that this program is not installed but is placed in a local folder. WinRAR is a utility typically used to create and read RAR files, compressed archives typically used to send or store files.
- Once this is done, the ArchiveLock Trojan will empty the infected computer's Recycle Bin, create a list of files on the infected computer that will be encrypted (typically media files, photographs and Microsoft Office documents), and delete all detected backups on the infected computer.
- The ArchiveLock Trojan uses WinRAR to create an archive with these files. This archive is password protected, meaning that one is not able to access it without the password associated with it.
- Finally, the original files are deleted from the infected computer.
Taking a Look at the ArchiveLock Trojan Ransom Note
As soon as the victim's files have been encrypted, the ArchiveLock Trojan displays a threatening message demanding the payment of $5,000 USD in exchange for the password. Security researchers advise against doing this or reinstalling your operating system and wiping your hard drive. It is possible to recover your files with the aid of anti-malware specialists or advanced anti-malware software.
