Isos Ransomware

Posted: September 30, 2020

The Isos Ransomware is a file-locking Trojan that's from Phobos Ransomware's family. The Isos Ransomware can block files with encryption, with a preferential focus on potentially-valuable media formats like documents. Users should ignore its ransom notes, if possible, recover through their backups, and let dedicated security tools delete any the Isos Ransomware infections.

The Database Where Every Entry Reads 'Danger'

File-locking Trojans may tip their hands when it comes to how they're circulating, which demographics they attack, and what their installations exploits are. Although many versions of the Phobos Ransomware family are more inscrutable than others, a recent case shows possible information that might help a victim sidestep any attacks. Of course, defending one's data against the Isos Ransomware's campaign also may use more conventional methods, such as a simple backup.

The Isos Ransomware family is a well-understood one, with examples starting from 2017. These campaigns include the Acton Ransomware, the Adage Ransomware, the 'fobosamerika@protonmail.ch' Ransomware or the  'tedmundboardus@aol.com' Ransomware. These threats' operating procedure consists of an initial encryption attack that blocks ransom-worthy files, such as documents, throughout the computer. The Isos Ransomware also can delete the Restore Points through a CMD command. Identifying any files thus converted to non-opening equivalents is straightforward since the Isos Ransomware appends an extension, which includes its name, e-mail address and a unique ID.

The Isos Ransomware's installer uses a fake database disguise, as per its name of 'db_exec,' but the format usually still is an executable or EXE. This theme makes the Isos Ransomware's campaign more likely to target corporate networks and other enterprise-grade entities, or smaller, unprotected business servers. Unfortunately, even Windows users at home are vulnerable to the Isos Ransomware's payload and its media-locking effects.

There's Little to Fear from Well-Understood Trojans

The Isos Ransomware's familial name comes from the personification of fear in Greek myth. The Isos Ransomware is no more or less harmful than similar threats with encryption routines despite the intimidating title. Users should save backups to other devices that can provide a reliable and free recovery option for any media, which renders the Isos Ransomware's payload a strictly-temporary problem. Although desperate victims might consider the ransom as the Isos Ransomware's HTA and TXT messages recommend, malware experts encourage any alternative, including freeware decryptors, where applicable.

Users should be mindful of infection methods that are more likely than others for the Isos Ransomware's campaign. Possibilities include:

  • E-mail attachments may embed exploits that can install Trojans. In most cases, users can avoid them by ignoring prompts for enabling macros or 'advanced' content and updating software such as Adobe Acrobat and Microsoft Office.
  • Threat actors also can access networks by breaching their login credentials by brute-force. Passwords of high complexity and uniqueness are mostly-safe from this method. Server software also should be well-maintained for removing associated vulnerabilities.

Trustworthy security products with threat removal features can remove the Isos Ransomware without qualms. Most products also identify it as a member of the Phobos Ransomware family correctly or a related one, the Crysis Ransomware.

Users have all the tools available for blocking a fear-inspiring Trojan like the Isos Ransomware, or any other offshoot of the Phobos Ransomware. That some choose not to do so and suffer the consequences is on their heads – and their files.
