Win32/SunnyDigits.D detection is a virus detection you can spectate in your computer. It usually shows up after the provoking activities on your computer – opening the untrustworthy email messages, clicking the advertisement in the Web or setting up the program from untrustworthy sources. From the moment it shows up, you have a short time to take action before it starts its harmful action. And be sure – it is much better not to await these malicious things.

What is Win32/SunnyDigits.D virus?

Win32/SunnyDigits.D is ransomware-type malware. It looks for the documents on your disk drives, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your documents locked, this malware also does a ton of harm to your system. It alters the networking setups in order to prevent you from reading the removal guides or downloading the anti-malware program. In some cases, Win32/SunnyDigits.D can even stop the setup of anti-malware programs.

Win32/SunnyDigits.D Summary

Summarizingly, Win32/SunnyDigits.D ransomware activities in the infected computer are next:

  • SetUnhandledExceptionFilter detected (possible anti-debug);
  • Dynamic (imported) function loading detected;
  • Reads data out of its own binary image;
  • Unconventionial language used in binary resources: Chinese (Traditional);
  • The binary contains an unknown PE section name indicative of packing;
  • Authenticode signature is invalid;
  • Harvests cookies for information gathering;
  • Anomalous binary characteristics;
  • Ciphering the documents kept on the target’s disk drive — so the victim cannot use these documents;
  • Blocking the launching of .exe files of anti-malware apps
  • Blocking the launching of installation files of anti-virus programs

Ransomware has actually been a major problem for the last 4 years. It is difficult to imagine a more damaging malware for both individuals and organizations. The algorithms used in Win32/SunnyDigits.D (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 already exists, and possibly will exist. But that malware does not do all these unpleasant things instantly – it can take up to several hours to cipher all of your files. Therefore, seeing the Win32/SunnyDigits.D detection is a clear signal that you must begin the removal process.

Where did I get the Win32/SunnyDigits.D?

Ordinary methods of Win32/SunnyDigits.D spreading are basic for all other ransomware examples. Those are one-day landing websites where users are offered to download the free software, so-called bait e-mails and hacktools. Bait emails are a pretty modern method in malware spreading – you get the email that simulates some regular notifications about shipments or bank service conditions updates. Inside of the email, there is an infected 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.

Preventing it looks quite easy, however, still needs tons of attention. Malware can hide in various spots, and it is much better to stop it even before it gets into your system than to rely upon an anti-malware program. Basic cybersecurity knowledge 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 lot of money and time which you would certainly spend while searching for a solution.
