How does this work?
Primarily, using Cobalt Strike's breg_query and breg_queryv functions. Then, all beacon output is hijacked with beacon_output, looking for specific values. When a positive match is made, the output will be highlighted in the beacon output. Since there is no beacon_output_reg or something similar, like beacon_output_ls and beacon_output_ps, all output must be captured for parsing.
What if my AV/EDR product isn't detected? / How can I help?
This is expected. We couldn't test for every AV/EDR solution, and we knew that many would be missing. You can help us out by submitting a GitHub issue including the following info:If this is a System/AV/EDR entryThe name of the productRelevant registry entries that can be used to positively ID the product

Do Email-Worms still a threat? And do they still capable of sending emails through Outlook?

I know that you can easily be infected with an Email-Worms just by launching an attachment, but are they still relevant?

I'm asking this because one of my friend's Outlook account is sending spam email to no one and a lot of it, so I want to know if that is a hacker or an Email-Worm.

Buffer Overflow - pass null bytes

Hello, I am working on a buffer overflow challenge, where I need to turn a given variable from 0 to 1. I can overflow and also point the variable to some memory I control.

The variable is part of a struct, which I recreate in the memory I control and point the software to it. I need it to be 1, so 0x00000001. When piping from python that is \x00\x00\x00\x01.

The issue seems to be that bash ignores the null byes: /bin/bash: warning: command substitution: ignored null byte in input . Thus the 1 is not passed to the program and written correctly.

What can I do about it, maybe use something else than python?

Thanks in advance for the help.
