Yolo Ransomware – Distribution Techniques

The Yolo ransomware samples have been captured in a low-volume attack campaign which doesn’t give out which is the main method. It is possible that the virus samples are early test releases or interim development versions which means that they can be used as the primary payload.

A popular method is the coordination of email SPAM messages which are used to send out fake notifications from well known companies and services. The files are sent directly as attachments or linked in the body contents. All of the interactive elements that are embedded can potentially be used to cause a virus infection: pop-ups, banners, text links and etc.

The Yolo ransomware can also be spread via malicious sites that use the same strategy — they attempt to confuse the visitors into thinking that they have accessed the real company or product site. Similar sounding domain names are used along with security certificates that may be self-signed or stolen. These are the primary warning signs that a potentially malicious page is being accessed.

The criminal collective behind the infections can also use payload delivery in order to infect the target machines. This relies on the code insertion into different files. Two of the most popular categories include the following:

  • Infected Documents — The code can be placed in macros in some of the most popular document types: spreadsheets, presentations, databases and text files. If they are opened by the victims a prompt will appear asking them to enable the built-in scripts. If this is done the virus installation will take place.
  • Setup Files — The virus code can be embedded in installers for a variety of popular applications: creativity suites, system utilities and productivity programs. When they are run the virus code will be implanted on the victim systems.

Larger campaigns can be achieved by implanting the samples in browser plugins — they are referred to as browser hijackers. Commoon places where they can be found include the relevant browser repositories where they are uploaded with elaborate descriptions and with fake user reviews. The goal of the hackers is to manipulate the visitors into thinking that they are going to install something useful that will add a new feature or in some way enhance their browser.

Yolo Ransomware – Detailed Analysis

The Yolo ransomware is based on the Jigsaw malware family which shows that the hacker or criminal collective behind it may not be very experienced. The captured samples are early test releases and the full code analysis is not yet available however we assume that the well-known behavior pattern will be executed here as well. The sources of these viruses are usually traded on the underground hacker forums. The hackers may have taken the Jigsaw code and modified it by themselves or they may have ordered a custom version from the dark web marketplaces.

The collected samples appear to include a stealth installation module which will sleep the virus before it launches its malicious components. This is done in order to evade heuristic scan of anti-malware and anti-virus programs which assume that infections will occur instantly after deployment.

Not surprisingly one of the first modules that are run is the data harvesting one. It is used to scan the system for sensitive information that is used to generate an unique ID for each affected machine. It is calculated by an algorithm that takes many input parameters: installed hardware components, system values and user settings. It can also be programmed to reveal the identity of the victim users: their name, address, phone number, interests and any stored account data and login details. This information can be used to carry out various crimes: identity theft, financial abuse and etc.

The Yolo ransomware sets itself in a memory guarded region which is a popular trick for disabling debug environments and virtual machine hosts. There are other security software that can be bypassed: anti-virus, firewalls and intrusion detection systems.

Once the Yolo ransomware has obtained control of the affected machines it will hook up to existing processes: both system and third-party ones. This will allow it to spy on the users interaction in real-time. This is very dangerous if coupled with a Trojan module — a local client that can establish a connection with a hacker-controlled server. The criminals will have the ability to take over control of the infected computers, steal their files and also deploy other malware.

Yolo Ransomware – Encryption Process

The ransomware engine will be called when the prior components have finished running. It will use a built-in list of target file type extensions which is typical of the Jigsaw ransowmare family. An example one will target the following data:

  • Archives
  • Backups
  • Databases
  • Music
  • Videos
  • Images

The code analysis shows that the following file type extensions are affected in one fo the captured samples:

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

The .Yolo extension will be applied to all victim files. The associated ransomware note will be a standard one, crafted in a text or HTML file.
