It often appears after the provoking procedures on your PC – opening the dubious e-mail, clicking the banner in the Web or setting up the program from untrustworthy sources.

What is Win32/Expiro.CP virus?

Win32/Expiro.CP is ransomware-type malware. It looks for the files on your computer, encrypts it, and then asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus additionally does a ton of damage to your system. It modifies the networking setups in order to prevent you from looking for the elimination tutorials or downloading the anti-malware program. In some cases, Win32/Expiro.CP can additionally block the setup of anti-malware programs.

Win32/Expiro.CP Summary

Summarizingly, Win32/Expiro.CP virus actions in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Creates RWX memory;
  • Dynamic (imported) function loading detected;
  • Enumerates the modules from a process (may be used to locate base addresses in process injection);
  • CAPE extracted potentially suspicious content;
  • Unconventionial language used in binary resources: Latvian;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • CAPE detected the RedLine malware family;

Ransomware has been a horror story for the last 4 years. It is hard to realize a more harmful virus for both individual users and organizations. The algorithms utilized in Win32/Expiro.CP (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy actually exists, and possibly will exist. But that virus does not do all these horrible things immediately – it can require up to a few hours to cipher all of your documents. Hence, seeing the Win32/Expiro.CP detection is a clear signal that you have to begin the elimination process.

Where did I get the Win32/Expiro.CP?

Routine ways of Win32/Expiro.CP distribution are typical for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a relatively modern strategy in malware distribution – you get the email that simulates some routine notifications about shippings or bank service conditions modifications. Within the e-mail, 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, however, still needs a lot of focus. Malware can hide in various spots, and it is better to prevent it even before it gets into your system than to depend on an anti-malware program. Essential cybersecurity awareness is just an essential thing 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 solution.
