What is Phobos-Acuff Ransomware

Being developed by the Phobos Ransomware family, Acuff puts up a strong lock on victim’s data by running encryption with cryptographic algorithms. This, therefore, restricts any attempts to recover data completely. After the attack has been committed, you may see your files change to something like this 1.mp4.id[C279F237-2275].[unlockfiles2021@cock.li].Acuff, which is a testament that your files have been infected. Acuff Ransomware uses the victim’s ID, cybercriminals’ email, and .Acuff extension to highlight the encrypted data. In order to help users restore their data, extortionists offer to walk your way through the note listing decryption instructions. The information can be found in two files called info.hta and info.txt that are created after encryption.

How Phobos-Acuff Ransomware infected your computer

Notoriously, cybercriminals use a number of ways to distribute ransomware infections. More often they use traditional spam through e-mail messages to deliver malicious attachments. As long as most users are not experienced enough to identify fraudulent activity, they open bundled attachments (MS Office documents, PDFs, executables, JavaScript files) by mistake, not knowing that it can contain malware. This is why you should learn the lesson and stop trusting content pervasively shown across the web. Do not open or interact with suspicious banners, ads, or links as they can lead to potentially dangerous websites. Before we launch you into performing removal and decryption instructions, it is necessary to mention that ransomware can also be spread via trojans, unprotected RDP configuration, fake tools for cracking licensed software, backdoors, keyloggers, and many others exceeding this list.
