What is Phobos ransomwarE? And how does it carry out its attack?

Phobos ransomware, also known as “Phobos”, is a file-encrypting Trojan that uses a unique victim ID and makes use of the AES encryption algorithm in encrypting the victims’ files. This ransomware spreads as an infected email attachment. Once it is inside the system, it begins to scan the computer for a variety of files to encrypt. According to researchers, it targets the files with the following formats:

PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.

As mentioned earlier, Phobos ransomware uses AES 256 encryption cipher to encrypt the targeted files. It also appends the ID.[<email].PHOBOS extension on each of the affected files. The ransomware uses a TOR-based Command and Control servers. After the encryption, Phobos displays a program window named “Your files are encrypted!” which has a logo for Phobos in the bottom-right corner of the window.

The ransom message displayed in the program window reads:

“All your files are encrypted

Hello World

Data on this PC runed into useless binary code

PHOBOS”

In its ransom note, Phobos indicated that the information stored on the affected computer was “turned into a useless binary code” and that victims must follow the ransom payment instructions given to recover the files. You should know better than to believe the ransom note as cyber criminals are not exactly known to keep their words. Hence, paying them won’t do you any good. It would be best if you try other alternative ways to recover your files – one of the effective ways to do so is through the files’ shadow volume copies. However, it would only work if Phobos hasn’t deleted them but it is still worth a try. If not, you can always use any backup copies of your files.

How does Phobos ransomware spread its malicious files?

Phobos uses the same old trick to spread its malicious files that most ransomware infection uses which is through malicious spam email a campaign. These kinds of emails often deceive users into downloading and opening the attachment. As a result, Phobos is installed in the system. Aside from that, the malicious files may also be embedded in an external web link which is also sent through email such as a button linking to a dropbox account and other forms of account for online file sharing where the malicious file can be downloaded directly.
