Epoblockl Virus – Distribution Techniques
Epoblockl virus is a new Hidden Tear-based strain which is being distributed by an unknown hacker or criminal collective. The detected attack campaigns appear to be launched mainly from the United States to other countries and regions, mainly countries in Northern Europe.
Such viruses are spread using several tactics at once in order to maximize the number of infected victims. We presume that the criminals behind them are going to popular scenarios and methods.
One of them relies on phishing email scams which are sent in bulk and disguised as originating from a well-known service or company that they use. The body messages will include messages and notifications that will coerce the recipients into opening a link leading to the virus file. An alternative approach is to directly offer an attached file to these emails.
The hackers can also construct fake web pages that impersonate well-known Internet portals, web pages, vendor sites and etc. Together with the email campaigns they are the primary distribution methods for malicious payloads. There are two popular types:
- Malicious Documents — The hacker group behind the Epoblockl virus can distribute it via macro-infected documents. Their built-in scripts will automatically launch a script that will download and execute the malware from a remote server. All popular document types can be used: databases, spreadsheets, presentations and text files. When they are opened by the users a notification message will appear asking them to run the built-in commands. If this is done the infection will begin.
- Malicious Setup Files —This strategy utilizes modified copies of well-known end-user software: creativity suites, system utilities or office programs. The hackers take the legitimate installers and embed the virus files in them. By being distributed through email messages and fake Internet portals the users may think that they are downloading a legitimate and safe application.
Such files can also be distributed via file-sharing networks, one of the most popular ones are the popular BitTorrent trackers. This is an often used as it is used to spread both legitimate and pirate content, especially software and games.
Massive virus campaigns with a wider outreach may adopt the browser hijacker approach. These are hacker-created browser extensions that are uploaded to the repositories of the most popular web browsers. Whenever they are installed the built-in settings will be modified to redirect the victims to a hacker-controlled page: the default home page, search engine and new tabs page. When this step has completed the Epoblockl virus will be deployed.
Epoblockl Virus – Detailed Analysis
The Epoblockl virus is base on the Hidden Tear malware family which is one of the most popular ransomware types. The source code of the main threat open-source and therefore easily acquired by both beginner and advanced hackers. This makes it very convenient to use as a base.
It is very possible that the criminal collective behind it has created this customization. The other hypothesis is that they have ordered it from the hacker underground markets.
Like other similar threats it will begin the infection with a data harvesting module. It is used to scan the system for variables that are used to construct an unique ID associated with each individual host: installed hardware components, operating system environment and user settings. This same component has been found to also look for strings that can directly expose the identity of the victims — their real name, address, email, phone number and any stored account credentials. It can scan both the local hard drive contents, operating system and data associated with the installed third-party apps.
The harvested information can also be used by another module used to bypass the security services available on the system. This is done by scanning for signatures of anti-virus engines, virtual machine hosts and sandbox environments. If the virus is unable to disable them it may opt to delete itself to avoid detection. The main virus engine can also create memory-guarded spaces which is an additional measure.
At this point the virus will have acquired control of the machines and will move onto causing changes such as the following:
- Windows Registry Changes — The ransomare engine can modify the entries belonging to the Windows registry belonging both to the operating system and any third-party installed applications. This can block certain functions or cause overall performance issues.
- Persistent Installation — The threat can be installed in a persistent state. This means that the Epoblockl virus will be launched every time the computer boots. This may also block access to the recovery menu which can render most manual removal instructions useless.
- Files Modification — The ransomware engine may delete sensitive user data such as System Restore Points, Backups and Shadow Volume data.
During its execution the Epoblockl virus may interact with the Windows Volume Manager and access any connected removable devices and network shares. This means that if a single computer on a given network is infected it can take over all potentially vulnerable hosts. Infections such as this one can also be used to deploy Trojan horses which are among the most dangerous types of malware. They will set up a client connection to a hacker-controlled server using a secure and persistent mechanism. This allows the operators to spy on the victims, take control over their computers and also deploy other viruses.
Epoblockl Virus – Encryption Process
As soon as all modules have completed the ransomware engine will be launched. It will use a built-in list of target file type extensions which will be processed with a powerful encryption algorithm. The captured samples showcase that the following files will be encrypted:
.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
All victim files will be renamed with the .Epoblockl extension, an alternative one is .Crypted with a capital “C”. A ransomware note is produced in a file called EPOBLOCKL-NOTE.txt which reads the following:
Your files have been encrypted with AES-128
