It frequently shows up after the preliminary activities on your computer – opening the dubious e-mail messages, clicking the advertisement in the Web or mounting the program from unreliable sources. From the second it shows up, you have a short time to take action until it begins its malicious activity. And be sure – it is better not to wait for these harmful actions.

What is DownWare (PUA) virus?

DownWare (PUA) is ransomware-type malware. It looks for the files on your disk drive, encrypts it, and after that asks you to pay the ransom for getting the decryption key. Besides making your files locked, this virus additionally does a ton of harm to your system. It changes the networking setups in order to prevent you from checking out the elimination manuals or downloading the antivirus. In some cases, DownWare (PUA) can additionally block the launching of anti-malware programs.

DownWare (PUA) Summary

In summary, DownWare (PUA) ransomware actions in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Presents an Authenticode digital signature;
  • Creates RWX memory;
  • Anomalous file deletion behavior detected (10+);
  • Dynamic (imported) function loading detected;
  • Reads data out of its own binary image;
  • Drops a binary and executes it;
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Ciphering the documents located on the victim’s disk drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-virus programs
  • Blocking the launching of installation files of anti-virus apps

Ransomware has been a headache for the last 4 years. It is hard to imagine a more hazardous malware for both individuals and businesses. The algorithms used in DownWare (PUA) (typically, 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 currently exists, and possibly will exist. However, that malware does not do all these unpleasant things immediately – it may take up to several hours to cipher all of your documents. Therefore, seeing the DownWare (PUA) detection is a clear signal that you need to start the clearing process.

Where did I get the DownWare (PUA)?

Ordinary methods of DownWare (PUA) spreading are typical for all other ransomware examples. Those are one-day landing websites where users are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware spreading – you receive the email that imitates some routine notifications about deliveries or bank service conditions changes. Within the email, there is a corrupted 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.

Avoiding it looks quite easy, but still requires a lot of awareness. Malware can hide in various places, and it is far better to stop it even before it invades your computer than to rely upon an anti-malware program. Essential cybersecurity awareness is just an important thing in the modern world, even if your relationship with a computer stays on YouTube videos. That may save you a great deal of money and time which you would spend while trying to find a solution.
