Ransomware has actually been a nightmare for the last 4 years. It is challenging to imagine a more damaging virus for both individual users and corporations. The algorithms used in MSIL/Injector.GBU (usually, 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 already exists, and possibly will exist. But that malware does not do all these terrible things immediately – it may take up to a few hours to cipher all of your files. Thus, seeing the MSIL/Injector.GBU detection is a clear signal that you should begin the elimination procedure.

Where did I get the MSIL/Injector.GBU?

Standard ways of MSIL/Injector.GBU spreading are basic for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free app, so-called bait emails and hacktools. Bait e-mails are a pretty modern tactic in malware distribution – you receive the email that mimics some standard notifications about shipments or bank service conditions changes. Within the e-mail, 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, however, still demands a lot of recognition. Malware can hide in various spots, and it is better to stop it even before it gets into your computer than to trust in an anti-malware program. Simple cybersecurity awareness is just an important item in the modern-day world, even if your interaction with a computer stays on YouTube videos. That may save you a lot of money and time which you would spend while searching for a solution.
