What is Banking Malware

How Banking malware deals with Web Application Security

Banking Malware Attack Process

The process involving Malware attack require the subsequent verification of each of the following steps to be successful. We consider an attack to be successful if the attacker obtain a financial gain from the initial client attack. The first two steps do not involve the Banking infrastrucure, while some other are tightly connected since attackers need to use the functionalities offered by the hacked online bank accounts to do cash outs.

From user infection to cash out process: (Image is missing)

This is a chain of required steps. Attackers need to perform successfully each of these for turning the attack into a monetary gain. For this reason the process can be reasonably stopped at any level. As in other cases a defense in depth approach is suggested to be effective against the weakest link of each part of the attack.

Infection of User clients and pcs Exploitation of client side vulnerabilities (during internet browsing) Spam (Infection delivered via Email)

Hiding The Infection and creating the Permanent threat Packers Modded Builds Rootkit (and Bootkit)

Stealing of Auth credentials KeyLogging and Form Grabbing Video Grabbing WebInjects

Storing of Auth credentials Standard Dropzone Fast Flux Based Server Instant Messaging and P2P network
