The AES-256 or RSA-1028 cipher it uses to cipher the documents is not decryptable with contemporary computers.

How did the Errz ransomware get on my computer?

The Errz ransomware spreads by posting websites to download hacked programs or games. They keep their eye on all hype subjects which can be used to spread ransomware. New games releases, new popular films – Errz creators make everything to get their money on that. Some of the most common methods these criminals utilize is one-day sites with torrent downloading links. Nevertheless, using the modern things is not the single tactic these criminals utilize. Methods that have already become standard, such as e-mail spamming, are also typical for STOP/Djvu ransomware distribution.

Malicious email spam
The example of email spamming that may lead to Errz ransomware injection

Preventing this ransomware does not require a lot of initiative. Adhering to the standard principles of PC hygiene will substantially minimize all risks. Keep in mind that opening all files you get on e-mail is not a great option. Even worse scenario is to allow macros in Microsoft Office documents. However, it is far better to prevent the malware intrusion at the moment when you have just opened the e-mail message. Inspecting the sender’s address can say a lot about what you can anticipate, and when you see things like “support@amazon.com”– it is likely a genuine email. At the same time, stuff that tries to look like Amazon or FedEx shipping alert, but uses the e-mail address of “amazonspurrot1363@gmail.com”– should make you be on the alarm. Above, you can see the example of such a message.

Illegal sources of various digital things need some extra description. Breaking copyright law surely exposes you to the possibility of being fined. Nevertheless, using torrent trackers or third-party sites to download “free” programs also exposes you to a wide range of malware. Nobody can control undisclosed people that launch the torrent seeding or release the hacked program version on the site with pirated program.
