ATLAS Ransomware

ATLAS Ransomware Description

The ATLAS Ransomware is a file encryption Trojan that appears to be a modified, and improved version of the CHIP Ransomware that emerged in November 2016. The ATLAS Ransomware is named after the tag attached to the encrypted files, which is '.ATLAS.' Reports of the threat surfaced on April 18th and analysis of the Trojan confirmed that it is derived from the CHIP Ransomware. Additionally, the payload for the Trojan is delivered to users the same way as many other crypto-Trojans are — spam emails carrying a macro-enabled document. The corrupted text document features an embedded script that directs the Windows OS to connect to a remote host, download a obfuscated file, unpack it and run the executable inside.

How the ATLAS Ransomware Compares to Other Crypto-Threats

When the ATLAS Ransomware is loaded in the memory of the computer, it may check if the system is running a debugger, which is a tool that cyber security experts use to analyze Trojans like the Malabu Ransomware and the MOLE Ransomware. The authors of the ATLAS Ransomware designed their product to hinder detection and debugging, which translates to more time it would take to build a virus signature and block the Trojan from computers. The ATLAS Ransomware is classified as a mid-tier encryption Trojan that functions a lot like the '' Ransomware. Both threats use the RSA and AES ciphers to lock data on the compromised machine; both threats are configured to work with 'Command and Control' servers hosted on the TOR Network and infected users are suggested to write an email to the ransomware operators who have an account on the privacy-centric ProtonMail platform. That way the crooks can remain anonymous and slow down the investigation of cases that involve their program. The threat at hand is proven to encipher the following types of data containers:

.pdf, .xls, .xlsx, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .7z, .zip

You can recognize the affected files by their generic white icon and the '.ATLAS' extension placed after the original format. For example, 'Fantail birds.pptx' is renamed to 'Fantail birds.pptx.ATLAS.' Unfortunately, the ATLAS Ransomware includes a procedure to erase the Shadow Volume Copies and System Restore points made by Windows. The ransom notification is presented as 'ATLAS_FILES.txt' that you may find in the Temp directory. The announcement reads:

Hello! All Your files are encrypted!
