Office Documents Poisoning in SHVE

Hello, folks! We’re back with an exciting update on Session Hijacking Visual Exploitation (SHVE) that introduces an insidious twist to traditional exploitation techniques using Office documents. We all know how Office documents laced with macros have been a longstanding entry point for infiltrating systems. SHVE now takes a step further by leveraging XSS vulnerabilities and the inherent trust users have in websites they regularly visit.

Our newest feature integrates the concept of Office document poisoning. Here’s how it works: SHVE allows you to upload templates for .docm, .pptm, and .xslm formats. Whenever a victim of SHVE goes to download one of these document types, the tool will automatically intercept and inject the malicious macros into the file before it is downloaded. What makes this technique particularly sneaky is that the document appears completely normal to the user, maintaining the original content and layout. However, in the background, it executes the malicious payload, unbeknownst to the user.


This approach capitalizes on two critical aspects: the trust users have in documents they download from legitimate websites they visit, and the inherent dangers of macros embedded within Office documents. By combining these two elements, we create a subtle vector for delivering malicious payloads. It’s the wolf in sheep’s clothing, where everything looks as it should be, but the danger lurks within.

To provide a clear demonstration of this technique, we’ve prepared a video illustrating this Office document poisoning in action. Witness how a seemingly innocent download can turn into a nightmare for the end user.

As security researchers and ethical hackers, we need to constantly evolve and adapt our methods. With this update, SHVE not only allows for the exploitation of XSS vulnerabilities but also cleverly abuses the trust mechanisms users have built around their daily digital interactions. This enhancement is not just a step forward in terms of technical capability, but also a reminder of the psychological aspects of security exploitation.

We’re eager to see how the community will leverage these new features in their penetration testing and red teaming engagements. As always, we welcome contributions, and we’re looking forward to your feedback and insights. Stay safe, and happy hacking!
