Contrasted with other ransomware developers, this is a low-end application.
Comparative manufacturers more often than not let law breakers to alter a more extensive arrangement of choices, such as, the Bitcoin deliver where to get installments, the payment request esteem, contact email address, and the sky is the limit from there.
The strategy is regularly used by malware engineers to make alleged “polymorphic malware” that is harder to recognize by standard antivirus programming.
As indicated by MalwareHunterTeam, “the manufacturer is extremely fundamental, so this shouldn’t help anything against genuine AVs.”
Firecrypt pathology procedure
The FireCrypt contamination prepare relies on the ransomware’s merchant’s capacity to trap clients in propelling the EXE record they just created.
When this happens, FireCrypt will terminate the PC’s Task Manager (taskmgr.exe) and start to encrypt a rundown of 20 document files.
FireCrypt encrypts records with the AES-256 encryption calculation.
All encrypted files will have their original file name and extension appended with “.firecrypt”.
Once the document encryption prepares closes, FireCrypt drops its payment note on the client’s Desktop.
The DDoS work that fills your hard drive with garbage records
Subsequent to dropping the payment note, FireCrypt doesn’t stop its noxious conduct. Its source code has a capacity that persistently interfaces with a URL, downloads its files and save into the hard disk.
