What is Epoblockl ransomware? And how does it carry out its attack?

Epoblockl ransomware is a crypto-virus that was first identified on November 14, 2018. Based on the analysis done on this crypto-malware, it is created using the HiddenTear open source platform and seems to be a variant of SYMMYWARE ransomware which was also released on the same month.

Once it carries out its attack, Epoblockl ransomware connects the infected computer to a remote Command and Control (C&C) server controlled by the attackers. From this remote server, Epoblockl ransomware downloads its other malicious components and place them on system folders. These malicious components are then used for the data harvesting module where it scans the computer for variables used to construct a unique ID associated with each individual host such as hardware components installed, user settings and operating system environment. This module also looks for strings that can directly expose the identity of the user like their real names, email address, location, phone number, as well as stored account credentials. The collected data is used for the second module, stealth protection, which is used to bypass the security services installed in the system. The stealth protection module is done by scanning the computer for any digital signatures of antivirus engines, sandbox environments and virtual machine hosts. Once it finds these programs, it will disable them and if it’s not able to do so, it deletes them altogether. And for additional measure, Epoblockl ransomware also creates memory-guarded spaces.

Epoblockl ransomware is also found to modify files in the Chrome extension folder where it may manipulate some browser extensions installed. Moreover, this crypto-virus also modifies and creates some entries in the Windows Registry. It is found to modify the following registry entries:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tracing\RASAPI32
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tracing\RASMANCS
  • HKEY_CURRENT_USER\Control Panel\Desktop\
  • HKEY_USERS\.DEFAULT\Control Panel\Desktop\
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

After it the registry modification, it scans the system for files with the following extensions:

.7z, .asp, .aspx, .avi, .bc6, .bc7, .bkf, .bkp, .cas, .cer, .csv, .d3dbsp, .doc, .docx, .fos, .gdb, .gho, .hkdb, .hplg, .html, .hvpl, .ibank, .icxs, .itdb, .itl, .itm, .m4a, .map, .mdb, .mdbackup, .mddata, .mov, .mp4, .odt, .php, .pkpass, .png, .ppt, .pptx, .psd, .qdf, .qic, .rar, .sb, .sid, .sidd, .sidn, .sie, .sis, .sql, .sum, .svg, .syncdb, .t12, .t13, .tax, .vdf, .wma, .wmo, .wmv, .xls, .xlsx, .xml, .zip, .ztmp

Once it finds its targeted files, it encrypts them using the AES 128 encryption algorithm and appends either the .Epoblockl or .Crypted extensions. It then drops and opens a text file named “EPOBLOCKL-NOTE.txt” which contains the following message:

“Your files have been encrypted with AES-128
