What is Ransom.Winlocker virus?

Ransom.Winlocker is ransomware-type malware. It searches for the files on your disks, ciphers it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this malware additionally does a lot of damage to your system.

Sometimes, Ransom.Winlocker can additionally prevent the launching of anti-malware programs.

In summary, Ransom.Winlocker malware actions in the infected system are next:

  • CAPE extracted potentially suspicious content;
  • Authenticode signature is invalid;
  • Binary compilation timestomping detected;
  • Ciphering the documents located on the victim’s drive — so the victim cannot use these files;
  • Blocking the launching of .exe files of security tools
  • Blocking the launching of installation files of anti-virus apps

Ransomware has actually been a major problem for the last 4 years. It is challenging to imagine a more damaging virus for both individual users and corporations. The algorithms used in Ransom.Winlocker (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these bad things without delay – it may take up to a few hours to cipher all of your documents. Hence, seeing the Ransom.Winlocker detection is a clear signal that you have to start the clearing procedure.

Where did I get the Ransom.Winlocker?

Routine methods of Ransom.Winlocker distribution are common for all other ransomware variants. Those are one-day landing sites where victims are offered to download and install the free software, so-called bait emails and hacktools. Bait e-mails are a relatively new strategy in malware distribution – you get the email that imitates some standard notifications about shippings or bank service conditions changes. Within the email, there is a corrupted MS Office file, or a 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 fairly simple, however, still requires tons of awareness. Malware can hide in different spots, and it is much better to prevent it even before it invades your PC than to rely upon an anti-malware program. Essential cybersecurity awareness is just an essential thing in the modern world, even if your interaction with a computer stays on YouTube videos. That may keep you a lot of time and money which you would certainly spend while trying to find a fix guide.
