Ransomware has actually been a horror story for the last 4 years. It is challenging to imagine a more dangerous malware for both individuals and corporations. The algorithms used in Win32/Injector.EJDH (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions.

Where did I get the Win32/Injector.EJDH?

Routine methods of Win32/Injector.EJDH injection are basic for all other ransomware variants. Those are one-day landing sites where victims are offered to download the free program, so-called bait e-mails and hacktools. Bait emails are a quite modern tactic in malware spreading – you get the e-mail that imitates some routine notifications about deliveries or bank service conditions changes. Within the email, 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 uncomplicated, but still demands tons of focus. Malware can hide in various spots, and it is much better to stop it even before it gets into your system than to depend on an anti-malware program. Basic cybersecurity knowledge is just an essential item in the modern world, even if your relationship with a computer stays on YouTube videos. That can keep you a lot of money and time which you would certainly spend while looking for a solution.
