What is Win32/Agent.UNQ virus?

Win32/Agent.UNQ is ransomware-type malware. It looks for the documents on your disk, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this malware additionally does a lot of damage to your system. It alters the networking setups in order to avoid you from checking out the elimination manuals or downloading the anti-malware program. In some cases, Win32/Agent.UNQ can even stop the launching of anti-malware programs.

Win32/Agent.UNQ Summary

Summarizingly, Win32/Agent.UNQ ransomware activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;
  • Unconventionial language used in binary resources: Russian;
  • Authenticode signature is invalid;
  • Collects information to fingerprint the system;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the documents kept on the victim’s drive — so the victim cannot open these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a major problem for the last 4 years. It is hard to realize a more dangerous malware for both individual users and organizations. The algorithms used in Win32/Agent.UNQ (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist. But that malware does not do all these horrible things without delay – it may require up to several hours to cipher all of your documents. Hence, seeing the Win32/Agent.UNQ detection is a clear signal that you must begin the clearing process.

Where did I get the Win32/Agent.UNQ?

Standard methods of Win32/Agent.UNQ spreading are usual for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a quite new strategy in malware spreading – you receive the email that simulates some routine notifications about shipments or bank service conditions shifts. Within the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks pretty easy, but still requires a lot of recognition. Malware can hide in various spots, and it is better to stop it even before it goes into your PC than to depend on an anti-malware program. Common cybersecurity awareness is just an important item in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can save you a lot of money and time which you would spend while looking for a fixing guide.
