Ransomware has actually been a major problem for the last 4 years. It is hard to imagine a more dangerous malware for both individuals and organizations. The algorithms utilized in Win32/Injector.CNJW (generally, 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 currently exists, and possibly will exist. But that malware does not do all these terrible things instantly – it may take up to a few hours to cipher all of your files. Thus, seeing the Win32/Injector.CNJW detection is a clear signal that you need to begin the elimination procedure.

Where did I get the Win32/Injector.CNJW?

Common methods of Win32/Injector.CNJW spreading are usual for all other ransomware variants. Those are one-day landing websites where victims are offered to download and install the free app, so-called bait e-mails and hacktools. Bait emails are a pretty new strategy in malware spreading – you receive the e-mail that imitates some routine notifications about deliveries or bank service conditions shifts. Inside of the e-mail, there is a malicious MS Office file, or a web link which opens the exploit landing site.

Malicious email spam

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

Avoiding it looks fairly simple, however, still requires tons of awareness. Malware can hide in different spots, and it is far better to stop it even before it gets into your computer than to trust in an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern-day world, even if your relationship with a PC stays on YouTube videos. That may save you a great deal of time and money which you would spend while searching for a fix guide.
