This one had a twist, though, this malware was not an attack in itself, it was an enabler, hiding on infected computers, establishing a proxy that other malware can then use to manage traffic to the PC and carry out their threats.
Webinjects work in a similar way to a formgrabber, but instead they intercepting data being sent from the website to the browser; The data interception is done after the data is decrypted (SSL) but before the browser displays it, giving the malware the ability to modify webpages on the fly.
HTTPS is built on top of the TLS/SSL cryptographic protocols and is designed to prevent MITM (man-in-the-middle) attacks, before the HTTP request is sent to the server it is encrypted using TLS/SSL, this means that any malware intercepting socket functions would receive encrypted data it could not read. The solution: Formgrabbers.
Under the hood ATS are simply just webinjects wearing a different hat, the purpose is shifted from gathering credentials for use/sale to automatically initiating wire transfers from the victims own computer…
