Some month ago I was wrote virus detector. I called it Perl_ii_detect_backdoor.pl. It was writen on Perl and can mass scan filesystem and check files (php) for backdoors and viruses. I was hunted on particular instance, but I was found match more modifications of it. Backdoor has some encrypted strings in each .php file and never repeat. My script excellent detect all infected files, and it was clean.
Long time ago miracle happen, and Perl_ii_detect_backdoor.pl rewriten to PHP and hosted as microsrvice: jkeks virus detector (JVD).
Algorithm is detect in source of internet page enrypted strings. Encrypted strings may be like base64 or another. It is of cause not 100% detect real virus or backdoor, but it may be very strange that source have encrypted things. It is abnomally, and need your attention.
