Win32/Agent.ACPN detection is a virus detection you can spectate in your system. It frequently appears after the provoking procedures on your computer – opening the suspicious email, clicking the banner in the Web or setting up the program from unreliable resources. From the second it appears, you have a short time to do something about it until it starts its destructive activity. And be sure – it is far better not to wait for these destructive effects.

What is Win32/Agent.ACPN virus?

Win32/Agent.ACPN is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this virus also does a lot of damage to your system. It alters the networking settings in order to stop you from checking out the removal guidelines or downloading the antivirus. Sometimes, Win32/Agent.ACPN can also block the setup of anti-malware programs.

Win32/Agent.ACPN Summary

In summary, Win32/Agent.ACPN virus activities in the infected system are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Behavioural detection: Executable code extraction – unpacking;
  • Creates RWX memory;
  • Guard pages use detected – possible anti-debugging.;
  • Dynamic (imported) function loading detected;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;

  • Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a headache for the last 4 years. It is challenging to realize a more damaging virus for both individuals and corporations. The algorithms used in Win32/Agent.ACPN (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy currently exists, and possibly will exist. However, that malware does not do all these bad things instantly – it may take up to several hours to cipher all of your files. Thus, seeing the Win32/Agent.ACPN detection is a clear signal that you must start the elimination process.

Where did I get the Win32/Agent.ACPN?

Standard tactics of Win32/Agent.ACPN spreading are usual for all other ransomware examples. Those are one-day landing sites where users are offered to download the free app, so-called bait emails and hacktools. Bait emails are a pretty new tactic in malware distribution – you get the e-mail that mimics some standard notifications about shippings or bank service conditions modifications. Inside of the email, there is a malicious MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks quite easy, but still demands a lot of attention. Malware can hide in various places, and it is far better to stop it even before it gets into your system than to depend on an anti-malware program. Basic cybersecurity awareness is just an important item in the modern world, even if your interaction with a computer stays on YouTube videos. That can save you a lot of money and time which you would spend while seeking a solution.
