.metan Ransomware – Distribution Techniques

The .metan ransomware samples have been discovered in a low-impact attack campaign showing that there is a high probability that they are early development or test releases. We anticipate that the most popular delivery tactics are to be used by the criminals.

Victims can acquire various virus infections through interaction with email SPAM messages that can carry the dangerous contents either as attached files or through clicking on the text or multimedia elements inside. Virtually all elements placed inside them can trigger the infection: banners, pop-ups, text links and etc. The messages are designed to appear as legitimate notifications sent by well-known companies or services that the users might know or use.

In many cases the criminals can also craft malicious web sites that may appear as legitimate portals, Internet pages, search engines and other commonly accessed places. They are hosted on similar sounding domain names to popular sites and may contain self-signed security certificates in order to look more trustworthy.

There are certain file payloads which can be used to spread the ransomware. A distinctive type is the infected application installer. The criminals can take the legitimate files of popular software which are used by end users and modify them with the virus code.

Another popular option is to insert the virus macros in documents across all popular types: spreadsheets, presentations, databases and text documents. Whenever they are opened by the users a prompt will be shown to them that requests that the scripts are executed. The quoted reason is that this is needed in order to correctly view the document.

.metan Ransomware – Detailed Analysis

As no code analysis has been made on the .metan ransomware samples we presume that they they are early test releases. As such we anticipate that future versions will include a whole array of the most common ransomware components. Most viruses of this category follow a typical behavior pattern.

A common tactic is to start the infection with a data harvesting procedure which is programmed to gather sensitive information about both the users and the infected machine. it will search for strings that can directly reveal a person’s identity and all collected information will be shared with the hackers. In addition the same engine can be reconfigured to extract machine information. It can be fed to a separate algorithm that will output an unique infection ID that is assigned to each compromised device. Other values that it uses is the list of installed hardware components, user setting and certain operating system environment conditions.

Using the obtained information the virus sample can cause a security bypass. This is a malicious action that will search for the installation of security software that can block the proper execution of the threat. Their real-time engines can be bypassed or entirely removed. Example one include firewalls, virtual machine hosts, anti-virus software and programming environments.

Future ransomware versions can cause serious issues as the .metan virus can hook itself to a legitimate process thereby spying on the user interactions. This also includes system services with administrative privileges. One of the most dangerous consequences is the modification of Windows Registry values — both those belonging to the operating system and third-party applications. This can lead to serious performance issues. In many cases this can render the computer completely unusable. As this can also affect the operations of standalone third-party applications the victims can experience loss of data and unexpected errors.

The system’s boot configuration can be changed as well which will install the ransomware as a persistent threat. Various options and configuration files will be modified in order to make the .metan ransomware automatically run as soon as the computer is powered on. This renders many manual user removal guides non-working as they depend on access to the recovery menus which will be disabled.

Other payloads can be delivered to the victims if such behavior is configured: Trojans, miners and hijackers.

.metan Ransomware – Encryption Process

Like other popular malware samples the .metan ransomware will launch the encryption engine once all prior modules have finished running. It will probably use a built-in list of target file type extensions which are to be processed by a strong cipher. An example list can include the following data types:

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

All affected files are renamed with the .metan extension. A ransomware note will be created containing the following message:

!!! ATTENTION, YOUR FILES WERE ENCRYPTED !!!
Please follow few steps below:
1.Send us your ID.
2.Then you’ll get payment instruction and after payment you will get your decryption tool!
Only we can decrypt all your data!
Contact us us:
[email protected]
And tell us your unique ID
[redacted 0x200 bytes in base64]
