What is CAGO ransomware? And how does it implement its attack?

CAGO ransomware is a data-encrypting malware that adds the “.CAGO” suffix to every encrypted file. It appears to be related to WALAN ransomware since they almost have the same content in their ransom notes except for the email addresses used but at the time of writing, it is yet to be proven.

CAGO ransomware follows the same pattern as other common ransomware infections. Once it infects a computer, it drops a malicious payload that will initiate the attack on the affected system. After its infiltration, it will download several malicious files from its remote server and puts them into system folders. Using these malicious files, CAGO ransomware employs an information gathering module used to gather information from the computer. The stealth protection module then follows which is the one that scans the system for strings of security programs, sandbox environments, and antivirus programs. After these modules are executed, CAGO ransomware modifies existing registry entries and creates new ones in order to allow it to run on every system boot automatically. This makes this crypto-virus a persistent threat. Once it achieves persistence, it begins encrypting its targeted files using a sophisticated encryption algorithm. It may target common user-generated files such as:

.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip

Following data encryption, it appends the .CAGO extension to each one of the affected files and releases a ransom note named “DECRYPT_INFO.txt” containing the content below:

“Hello, dear friend.

All your files are encrypted with a unique key.

Are you sure you want to recover all your files ?

Write us an email: popstop@foxmail.com

Enter your unique ID in the message: [redacted 10 lowercase hex]”

It isn’t practical to contact these crooks as you could end up losing not just your money, but the compromised data as well. The best thing you can do when infected with this ransomware Trojan is to remove it carefully from your system first and then try out free recovery options, be it through a free decryption software or using the Windows Previous versions feature.

How is the malicious payload of CAGO ransomware distributed over the web?

The malicious payload of CAGO ransomware may be distributed via spam emails. Cyber criminals, particularly ransomware developers, often use this distribution method where they attach an infected file to emails. As soon as users open the infected file, it will install CAGO ransomware into the system right away. This is why you must be careful in opening emails and downloading their attached files as it could be a malicious payload of some dangerous threat like CAGO ransomware.

Eliminate CAGO ransomware from your infected computer with the help of the following removal guide.

Step 1: First, tap the Ctrl + Shift + Esc keys in your keyboard to open the Task Manager.

Step 2: After opening the Task Manager, go to the Processes tab and look for any suspicious-looking process that takes up most of your CPU’s resources and is most likely related to CAGO ransomware.

Step 3: After that, close the Task Manager.

Step 4: Tap Win + R, type in appwiz.cpl and click OK or tap Enter to open Programs and Features under Control Panel.

  • %TEMP%
  • %WINDIR%\System32\Tasks
  • %APPDATA%\Microsoft\Windows\Templates\
  • %USERPROFILE%\Downloads
