Ransomware has been a horror story for the last 4 years. It is challenging to imagine a more harmful malware for both individuals and organizations. The algorithms used in Trojan:Win32/NabucurObfs (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy already exists, and possibly will exist. But that virus does not do all these unpleasant things immediately – it can take up to a few hours to cipher all of your documents. Therefore, seeing the Trojan:Win32/NabucurObfs detection is a clear signal that you should begin the removal process.

Where did I get the Trojan:Win32/NabucurObfs?

Ordinary tactics of Trojan:Win32/NabucurObfs distribution are usual for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a relatively new method in malware distribution – you receive the email that simulates some routine notifications about shippings or bank service conditions shifts. 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 pretty simple, however, still requires a lot of awareness. Malware can hide in various places, and it is far better to stop it even before it goes into your system than to trust in an anti-malware program. Simple cybersecurity awareness is just an important item in the modern world, even if your relationship with a PC remains on YouTube videos. That can save you a great deal of time and money which you would certainly spend while searching for a fixing guide.
