Customer's project analysis: "A 3-node cluster is not possible because of network limitations (an ethernet cable only has two ends!)"

Long story short: To prove a point, I built a twisted-pair Ethernet "cable" with 3 ends. I've only gotten it to work with 10BASE-T and autonegotiation disabled though.

New research πŸ‘‰ Exception Oriented Programming, Part 2: Weaponizing Fundamental Weaknesses in Exception Unwinding to Gain Code Execution https://billdemirkapi.me/abusing-exceptions-for-code-execution-part-2/
Abusing Exceptions for Code Execution, Part 2

In this article, we'll explore how the concepts behind Exception Oriented Programming can be abused when exploiting stack overflow vulnerabilities on Windows.

Disclosing CHOP, aka how attackers can bypass commodity return address protections such as stack cookies by hijacking the exception handling process. Paper to appear NDSS'23, fetch our preprint here: https://download.vusec.net/papers/chop_ndss23.pdf! Joint work of Victor Duta, Fabian Freyer, @pagabuc, @nsr, and @c_giuffrida.

Interested in smashing stacks or binary exploitation in general? In case you attend Backhat Europe next week, feel free to checkout Victors's and Fabian's talk "Unwinding the Stack for Fun and Profit" next Wednesday.

They will present our work on confusing the unwinder and bending exception handling for exploitation.
