24H Virus – Distribution Ways

The 24H virus has been discovered in an ongoing hacker attack with a limited scope. A single successful infiltration has been reported in Africa which signals two possible cases scenarios:

  • The attacks are coming in from a hacker group that is testing a newly created virus.
  • The hacker or criminal group behind the attack has acquired custom code from the underground markets and are testing it on test targets.

The 24H virus can be distributed using phishing email campaigns that are created in bulk and coordinated by the the hackers behind the virus. They use social engineering tactics by taking the design elements and text from notifications that have been sent by famous companies and services. By using the customized emails the hackers can confuse the victims by offering the ransomware strains either hyperlinked or attached directly to the messages.

The hacking group may also create fake download sites that together with the email messages can be used to spread the infected payloads that are another technique used to infect many computer users.

There are two primary types that are the most common ones — the first one relies on the insertion of code into documents such as presentations, text files, spreadsheets or databases. Once they are opened by the victims they will be presented with a notification box asking them to enable the built-in scripts. This will activate the macros that lead to the virus delivery. A similar strategy is used with application installers where the criminals bundle the virus code into software install packages. The typical targets are popular programs that are usually preferred by the majority of end users: system utilities, creativity suites and productivty apps. The hacker-created strains are made by taking the legitimate installers from te official vendor download sites and releasing the fake packages through the download sites and email messages.

Another virus delivery strategy relies on the use of browser hijackers that seek to infect the victim’s web browser and modify the default settings by redirecting the victims to a hacker-controlled page. During this process they may also also hijack sensitive data from the victim machines. The hijackers are usully distributed on the relevant web browser plugin repositories using fake developer credentials and user reviews.

24H Virus – In-Depth Analysis

The captured strains of the 24H virus are described to be early test releases that do not constitute a finished product. At the same time we have received reports that a victim has been infected with it which shows that there is true damage potential. While the ransomware engine is the only malicious component that is included in the captured released, it’s engine can be modified to include other components as well. Future released of the 24H virus may follow the behavior patterns instituted by typical ransomware.

The usual way that a virus infections is by starting a data harvesting component. It scans the memory and hard drive contents of the infected hosts by looking for specific strings that can reveal the victim’s identity. The data includes strings such as the user’s name, address, telephone number, interests and account credentials. Other information that is acquired is related to the attack campaign itself. The harvested data can be used to gain insight into the types of infected machines. The engine can collect certain values about the operating system and the installed hardware components.

This data can be processed by the next engine responsible for keeping the virus running in the presence of security countermeasures. The information about the installed software and running services may allow the virus engine to disable any real-time engines belonging to anti-virus software, debug/sandbox environments and virtual machine hosts.

Other 24H virus related damage to the host system can include a variety of system manipulation actions that include any of the following:

  • Windows Registry Manipulation — The 24H virus can be used to change the Windows Registry entries belonging to user-installed applications and system services, consequently certain functions can stop working. Overall performance is also affected.
  • Persistent Threat — The 24H virus can be installed to the hosts as a persistent threat. This means that it will automatically execute itself when the computer boots. This behavior is also accompanied by the removal of access to the boot recovery menu and certain options that are used to manually remove the active infections.
  • Trojan Service — The 24H virus engine can connect to a hacker-controlled service which can be used to take over control of the infected machine. The Trojan service allows the hackers to spy on the users, as well as deploy additional threats.
  • Files Deletion — The associated component responsible for the system changes can also delete all found Shadow Volume Information and System Recovery snapshots to make data recovery more difficult. In these cases the victims will need to resort to a professional-grade data recovery solution.

24H Virus — Encryption

When all components have executed correctly the ransomware engine is started. It uses a strong cipher in order to target files according to a built-in list of target files. The list can include any of the folloiwing types: documents, archives, backups, images, music, videos, databases and etc.

All of the data is renamed with the .24H extension. The ransomware note is created in a file called ReadME-24H.txt which reads the following:

Welcome to the “24H” Ransomeware! all your system information is encrypted. For receive the decryption program, transfer 0.24 bitcoins to 1FniWsB6T3n7GjBGs3UizspTshBvt9qFqR address and then send your request to the “24H@tutanota.com” and “24HDecryptor@Mail.ru” email addresses.
