What is Troj/Urelas-I virus?

Troj/Urelas-I is ransomware-type malware. It searches for the files on your disk drive, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this virus additionally does a lot of harm to your system.

Troj/Urelas-I Summary

In total, Troj/Urelas-I virus actions in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Sample contains Overlay data;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • Drops a binary and executes it;

Ransomware has actually been a horror story for the last 4 years. It is challenging to realize a more dangerous malware for both individual users and organizations. The algorithms used in Troj/Urelas-I (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 horrible things immediately – it may take up to a few hours to cipher all of your documents. Therefore, seeing the Troj/Urelas-I detection is a clear signal that you need to start the removal process.

Where did I get the Troj/Urelas-I?

Standard methods of Troj/Urelas-I injection are standard for all other ransomware examples. Those are one-day landing sites where victims are offered to download and install the free program, so-called bait emails and hacktools. Bait emails are a quite modern strategy in malware spreading – you receive the e-mail that imitates some normal notifications about deliveries or bank service conditions modifications. Inside of the e-mail, there is a malicious MS Office file, or a link which leads to the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks quite simple, however, still demands tons of attention. Malware can hide in different spots, and it is much better to stop it even before it invades your PC than to trust in an anti-malware program. Essential cybersecurity knowledge is just an important thing in the modern world, even if your interaction with a PC remains on YouTube videos. That can save you a lot of time and money which you would certainly spend while trying to find a fixing guide.
