.aes128ctr Ransomware — Update August 2019

A new version of the .aes128ctr ransomware, otherwise known as MegaCortex has been discovered in a worldwide attack release. The new release is designated as Megacortex v2 in the security reports and at the moment it appears to target enterprise targets both in Europe and across the United States.

In the moment instead of sending out the common phishing strategies the infection is distributed via other threats, examples include Emotet and Qbot.

As soon as the payload is dropped into the target systems the main engine will be automatically started. This particular threat includes the possibility to infect other hosts available on the local network. This is made possible by first running an security bypass function — the ransomware will identify if there are any installed and running software that may block the proper functioning of the .aes128ctr files virus:

  • Anti-Virus Engines
  • Firewalls
  • Intrusion Detection Software
  • Virtual Machine Hosts and Debug/Programmer Environments

The main MegaCortex ransomware is delivered in an encrypted form and decrypted in real-time, this is made in order to make it harder to notice the infection. What’s more dangerous is that this updated veresion of the .aes128ctr ransomware (MegaCortex v2 Ransomware) can be programmed to execute a variety of other threats, especially in this case when it is directed against enterprise users.

The .aes128ctr ransomware is a new virus which is also known as the MegaCortex ransomware. At this moment there is no information available about the origins of the attacks and the criminal collective behind it. We anticipate that the most popular mechanisms will be used. They include the creation of email SPAM campaigns which are used to pose as legitimate and well-known companies and services that coerce the victims into thinking that they need to interact with a given script or file.

A similar mechanism is the creation of malware sites that impersonate search engines, portals, landing pages and etc. They are hosted on similar sounding domain names that may seem safe to the victims. To make them appear as more legitimate the hackers can host the sites with security certificates that can be either stolen or self-signed.

The relevant .aes128ctr ransomware code can also be bundled with payload carriers such as setup files and malware documents. Popular applications which are targeted include the most popular software which are used by end users. When it comes to documents all of the most popular formats can be affected: presentations, text documents, databases and spreadsheets. In other cases the necessary virus code can be placed in browser hijackers which are dangerous plugins made for the most popular web browsers. The malware samples are uploaded to the repositories of the web browsers with fake credentials and reviews.

The available information about the virus is that it will launch a complex file encryption process which appear to be run as soon as the infection is made. It is very possible that other modules will be launched as well:

  • Information Gathering — The .aes128ctr ransomware like other popular threats can be configured to hijack sensitive data that can reveal information about the infected machines and can reveal private information about the victim users. Some of the samples have been confirmed to be harvest the following data: cryptographic strings, CPU information, active computer name, processes and Windows Registry values.
  • Security Bypass — Any programs that can block the normal virus infections can be bypassed by advanced ransomware: anti-virus engines, firewalls, sandbox environments and virtual machine hosts.
  • System Changes — All kinds of modifications can be done to the system. They can include boot changes which will automatically start the threat as soon as the computer is powered on. If Windows Registry changes are made then unexpected errors and data loss can occur.
  • Additional Malware Delivery — In certain situations active .aes128ctr ransomware infections can be used to deploy other threats such as Trojans, miners and hijackers.

What’s dangerous about the MegaCortex ransowmare is that it has the ability to manipulate a wide range of system services and options:

  • Software Policy Settings — This means that the ransomware engine will reconfigure the options used by individual applications and services. A common reason for doing so is the lowering of the security options which can trigger easier infections for other types of malware: hijackers and miners for example.
  • Proxy Settings — Such changes will redirect the victim’s Internet traffic via a proxy server thus enabling the hackers to spy on all of their activity.
  • Running Applications Monitoring — At any time the virus engine can scan the running processes and hook up to them which means that the criminals will be able to spy on the activities of the users.

As soon as all modules have finished running the actual encryption will start. A very strong cipher will be applied to sensitive user data, usually a built-in list of target file type extensions will be used. When processed the associate .aes128 ctr extension will be applied to them. In order to blackmail the victims into paying the hackers a decryption fee a ransomware note called !!!_READ_ME_!!!.tx will be made.
