What is TrojanDownloader:Win32/Dluca virus?

TrojanDownloader:Win32/Dluca is ransomware-type malware. It searches for the documents on your disk drive, encrypts it, and after that asks you to pay the ransom for receiving the decryption key. Besides making your files inaccessible, this malware additionally does a ton of harm to your system.

TrojanDownloader:Win32/Dluca Summary

Summarizingly, TrojanDownloader:Win32/Dluca virus actions in the infected PC are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • HTTPS urls from behavior.;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Attempts to modify proxy settings;
  • Creates a copy of itself;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Ciphering the documents located on the victim’s disks — so the victim cannot check these files;

Ransomware has actually been a nightmare for the last 4 years. It is hard to realize a more damaging virus for both individuals and businesses. The algorithms used in TrojanDownloader:Win32/Dluca (generally, 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 can take up to a few hours to cipher all of your documents. Thus, seeing the TrojanDownloader:Win32/Dluca detection is a clear signal that you need to begin the elimination process.

Where did I get the TrojanDownloader:Win32/Dluca?

Usual ways of TrojanDownloader:Win32/Dluca distribution are usual for all other ransomware variants. Those are one-day landing web pages where users are offered to download the free program, so-called bait emails and hacktools. Bait e-mails are a quite new strategy in malware spreading – you get the e-mail that simulates some normal notifications about deliveries 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.

Avoiding it looks fairly easy, but still demands tons of focus. Malware can hide in different spots, and it is better to stop it even before it goes into your computer than to trust in an anti-malware program. Simple cybersecurity knowledge is just an essential thing in the modern world, even if your relationship with a computer remains on YouTube videos. That may save you a lot of time and money which you would certainly spend while searching for a fixing guide.
