Visualization of a file – before and after encryption:įiles with the same plaintext produce different ciphertexts, that leads to the conclusion that each file is encrypted with a new key. It is deployed via WScript running the default Microsoft voice-to-speech service – just like in the case of Cerber.Įncrypted files are added to the “sage”extension and their icons are changed: In addition to the written information, Sage 2.2 plays a voice message informing about the infection. In version 2.2 the wallpaper looks very similar to 2.0, except the font is green instead of red:Īt the end of the execution, the ransom note !HELP_SOS.hta opens automatically: However, if the ransomware successfully completed encryption process and deleted itself, the link is left abandoned.Īfter finishing, the wallpaper is changed. Just in case the system gets restarted before the encryption finished, Sage sets a link in the Startup folder, so that it can continue after the reboot: As we can see, the ping command is used to delay operations. Sample contents of the batch scripts is given below. We can see the batch scripts and the BMP that is being set as a wallpaper: The content dropped in %TEMP% is shown on the below picture. Example: "C:\Users\tester\AppData\Roaming\FkGtk5ju.exe" gĪfter finishing its work, that dropped copy is also being deleted with the help of a batch script dropped in the %TEMP% folder. The dropped copy deploys itself once again, with a parameter ‘g’. Behavioral analysisĪfter being deployed, Sage deletes the original sample and runs another copy, dropped in %APPDATA% (names of the dropped files are different for different machines – probably generated basing on GUID): In the analyzed case, the sample was dropped via a JavaScript file. Most often, Sage is dropped by downloader scripts distributed via phishing e-mails (office documents with malicious macros or standalone JS files). The malware is actively developed and currently, we are facing an outbreak of version 2.2. Similarly to Spora, it has capabilities to encrypt files offline.
