How To Remove Kirk Ransomware Infection From Your PC (Virus Removal Guide)

Malware researchers have discovered the Kirk ransomware which encrypts target user data and is Star Trek themed, continue reading our removal guide to learn more.

Kirk Ransomware Description

Star Trek fans and computer users have one more reason to worry as computer hackers have devised a ransomware that is named after the famous saga. The infection follows the usual behaviour patterns by encrypting target user data with a strong cipher.

The initial security analysis does not show a clear connection between this particular threat and one of the famous malware families (such as EDA2, HiddenTear, Cerber and others) which means that the ransomware is created by an independent hacker or collective.

While the virus does not seem to be made by a famous entity, we have observed some advanced features that sets it apart from other similar threats:

  • Stealth Protection – The virus has been found to feature a module which prevents analysis by detecting any running debugging tools.
  • Volume Information Query – The ransomware is able to query information about the mounted partitions (disk drives) and all mapped networks shares.
  • Creates Numerous Temporary Files – The ransomware engine is able to create numerous temporary files which are placed in various locations (both user and system folders).
  • Hardware Interface – The virus is able to connect to devices and services over the LPC ports.

Upon infection the virus follows the same basic behavior patterns used by other similar threats. The virus immediately starts to create temporary files to prepare its encryption engine, while at the same time using an anti-debugging shield to protect itself from analysis or security solutions. The researchers uncovered that the virus can modify and drop all kinds of data which can cause system changes that might impact performance. It seems that the engine is written in the popular Python programming language.

The encryption engine is then started which employs a powerful cipher which targets a number of file type extensions. All affected files receive the .kirked extension and then the following ransomware note is displayed:

There are an additional 441 file extensions that are targetted. They are mostly to do with games.
To get your files back, you need to pay. Now. Payments recieved more than 4e hours after
the time of infection will be charged double. Further time penalties are listed below.
The time of infection has been logged.
Any files with the extensions listed above will now have the extra extension ‘.kirked’, these files
are encrypted using military grade encryption.
In the place you ran this program from, you should find a note (named RANSOM_NOTE.txt) similar to this one.
You will also find a file named ‘pwd’ – this is your encrypted password file. Although it was generated by your computer, you have no way of ever decrypting it.
This is due to the security of both the way it was generated and the way it was encrypted. Your files were encrypted using this password.

0 crypting your files is easy. Take a deep breath and follow the steps below.

4) Breathe.

LIVE LONG AND PROSPER.

From the note we can obtain more details about the virus and its behaviour. As it appears the the creators of the threat request the recovery fee in the Monero crypto currency which is an alternative to the widely used Bitcoin system. The virus computers an unique ID of the infected machine which is based on several key variables. Like other viruses of this type the ransomware wants to achieve maximum profits, the hackers behind this threat request a different payment sum depending on the “age” of the infection.

The Kirk ransomware presents Star Trek-themed ASCII art in the note and also uses the widely used phrase/quote “Live Long and Prosper” in the end.

Kirk Ransomware Distribution

The collected malware samples are too limited in number to judge a primary infection method. We believe that the creators of the ransomware have used the following tactics to infect the compromised machines:

  • Email Spam – The hackers employ bulk email spam messages which use social engineering tricks to try and infect the target users. Such phishing techniques usually employ body text and files that appear to be sent by legitimate companies or institutions. The most likely used scenario is the use of infected documents that feature malicious macros. Upon interaction with them the payload is delivered to the host system.
  • Download Sites and P2P Networks – Compromised or hacker-controlled download sites are a popuar place for distributing all kinds of dangerous viruses. BitTorrent trackers are another source of infections.
  • Infected Software Installers – The Kirk ransomware can be bundled with software installers distributed over the Internet. This includes a wide variety of well-known applications, games, tools, patches or utilities. Depending on the attack campaign this can include both freeware or trial versions.
  • Direct Attacks – Attacks that use exploit kits or vulnerability testing frameworks can institute remote access and infection with the Kirk ransomware.
