What is Win32/Agent.ACGU virus?

Win32/Agent.ACGU is ransomware-type malware. It searches for the documents on your computer, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this virus additionally does a lot of damage to your system. It alters the networking settings in order to stop you from checking out the elimination tutorials or downloading the anti-malware program. In some cases, Win32/Agent.ACGU can even stop the setup of anti-malware programs.

Win32/Agent.ACGU Summary

Summarizingly, Win32/Agent.ACGU virus actions in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Detects Sandboxie through the presence of a library;
  • Detects Avast Antivirus through the presence of a library;
  • Checks for the presence of known devices from debuggers and forensic tools;
  • Checks the presence of disk drives in the registry, possibly for anti-virtualization;
  • Anomalous binary characteristics;
  • Ciphering the files located on the victim’s disk — so the victim cannot check these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a nightmare for the last 4 years. It is difficult to realize a more hazardous virus for both individuals and businesses. The algorithms used in Win32/Agent.ACGU (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 actually exists, and possibly will exist. However, that malware does not do all these bad things without delay – it can take up to a few hours to cipher all of your files. Hence, seeing the Win32/Agent.ACGU detection is a clear signal that you need to start the elimination process.

Where did I get the Win32/Agent.ACGU?

Common ways of Win32/Agent.ACGU spreading are common for all other ransomware variants. Those are one-day landing websites where victims are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a pretty modern method in malware spreading – you get the e-mail that imitates some standard notifications about shipments or bank service conditions shifts. Inside of the e-mail, there is an infected MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks quite uncomplicated, but still requires tons of attention. Malware can hide in different spots, and it is much better to prevent it even before it goes into your system than to depend on an anti-malware program. Simple cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a computer remains on YouTube videos. That can keep you a lot of time and money which you would spend while searching for a fix guide.
