This is simply encoding a configuration file inside a JPEG to hide updates to an existing infection. OP seems being inquiring about JPEG visuals as a vector for transmitting new bacterial infections.
The cybercriminals are exploiting a vulnerability which allows them to spoof file extensions, meaning that they are able to cover the launch of malicious code in just an archive masquerading as a ‘.
!). With all the analysis you may have accomplished I am leaning towards this reply. intending to hold out somewhat for a longer time to discover if any individual else has any feelings. could you provide information on how a PIF launches a MS Dos app (just like a dos cmd prompt, for foreseeable future website visitors)?
Well, integrated .jpg files are parsed and executed as any other file would be, and thus PHP code inside jpg exploit it will be executed. This example is a tiny bit significantly fetched, but it isn't fully inconceivably that anything like this might exist. tl;dr: you may execute jpg information as PHP documents by means of .htaccess or by way of involve. Additionally, you may be able to bypass the file extension Verify whether it is insecure.

utilizing a rubegoldberg impression and canvas etcetera will only do two points: limit the browsers you'll be able to deliver the payload; and ensure it is much easier for anti-virus/firewalls to detect you (trace: they are going to dismiss the payload and focus on the sophisticated code to unwrap it, which now will flare up on anyones radar)
