Hi all,

I would like to disclose a vulnerability that I just found today.

Details below:

Vulnerable Software and Version:

1. Rufus 3.17.1846 executable
2. Rufus 3.17.1846 portable executable

Vulnerable software download link:
https://rufus.ie/en/

https://github.com/pbatard/rufus/releases/tag/v3.17

Date discovered and reported:
25 Feb 2022

Description:
Both Rufus 3.17.1846 executable AND portable executable are suffering from DLL
Hijacking by placing x86 MSASN1.dll or VERSION.dll in the same directory as
the executables, which could cause arbitrary code execution and privilege
escalation.

Taking MSASN1.dll as an example, craft a malicious x86 DLL with an entry
point with DllMain and place in the same directory, once double click the
executable, an x86 admin shell could be obtained as the executable requires
admin right to run by design.

Attack vector:
Taking MSASN1.dll as an example PoC code of dll can be found in my
repository

Attack steps:

1.

Craft and drop a malicious DLL named as "MSASN1.dll" with entry point
DllMain [image: image]
<https:
2.

Double click the executable "Rufus", administrator privilege is required
to run
3.

Malicious DLL has been called and an admin shell can be obtained as
PoC [image:

This issue has been submitted to github as well and is acknowledged by the
owner,

Thanks and regards,

Is it illegal to possess data leaked from a breach?

Let's say Company X was breached, and the attackers leaked the data publicly (or to the dark web). Could you get in legal trouble for downloading that data? I guess it's like possession of stolen goods, which is a crime, but what if you're a security researcher? Of if you're a customer of Company X, and want to see if any of your data is included in the breach?

Am I the only one that feels like NetworkChuck is overrated?

When I started my hacking journey, I came across NetworkChuck a couple times in Youtube. When you look at their titles, they look very promising, but when you actually check the content of the video and try it out practically, around 80% of things often don't work or doesn't work you expect to do so.

I don't know if it's a good place to talk about it here, but I'm just wondering what you guys think about that
