First found by using MalwareHunterTeam, ANDRZEJ DUPA is a new version of a ransomware-type virus called BansomQare Manna. at once after infiltration, ANDRZEJ DUPA encrypts maximum stored facts and appends filenames with the “.ZaszyfrowanePliki” extension (e.g., “pattern.jpg” is renamed to “sample.jpg.ZaszyfrowanePliki”). as soon as encrypted, statistics will become not possible to apply. After successfully compromising documents, ANDRZEJ DUPA opens a pop-up window and creates a text record (“ZaszyfrowanePliki.txt”), placing a duplicate in each present folder.
The pop-up window carries a message informing customers of the present day situation and instructing them what to do next. it’s miles said that files are encrypted and that a completely unique decryption secret is essential to repair them. unfortunately, this facts is accurate. it’s miles presently unknown whether or not ANDRZEJ DUPA uses symmetric or uneven cryptography – this data is not provided, but, decryption calls for a key generated in my opinion for each victim. lamentably, cyber criminals keep all keys on a remote server, allowing them to blackmail victims. To retrieve their keys, victims ought to pay a ransom of $100 in Bitcoins. The pop-up window additionally carries a countdown timer. as soon as it reaches zero, the cost supposedly increases. customers also are accredited to send a number of files to those criminals through email. The rogue developers then repair and go back them to the sufferer, thereby supposedly ensuring that decryption is possible. In truth, cyber criminals can never be trusted. those people ignore sufferers, once payments submitted – paying generally gives no nice end result and customers are scammed. We strongly endorse which you ignore all requests to post payments or touch those humans. alas, there are no tools able to restoring facts compromised by way of ANDRZEJ DUPA. consequently, there may be only one solution: to repair the whole lot from a backup.
ANDRZEJ DUPA is honestly same to Sequre, Kraken 2.zero, nRansom, Spartacus, and dozens of other ransomware-type viruses. be aware that, despite the fact that these viruses are advanced via distinctive cyber criminals, their conduct is equal – all encrypt information and make ransom needs. There are simply predominant differences: 1) length of ransom, and; 2) kind of encryption set of rules used. alas, most rent algorithms (RSA, AES and comparable) that generate particular decryption keys. consequently, except the malware is not fully developed or has positive bugs/flaws, restoring documents manually with out involvement of developers (contacting those humans isn’t always recommended) is impossible. Viruses including ANDRZEJ DUPA are one of the primary motives to preserve ordinary statistics backups, however, it is very important to shop everything on an unplugged storage tool (e.g., Flash force, external difficult power, and many others.) or faraway server (e.g., Cloud), in any other case backups are encrypted together with ordinary information.
