Obfuscation Nation in shambles?
Static Devirtualization of Themida
Hackers say this code lockpicker could crack way more than one “unbreakable” shield
TLDR: A new write-up shows how to strip away a famous layer of software disguise, and the bigger shock is that the same trick may work on many similar systems. Commenters zeroed in on that broader claim and instantly started pushing for an even tougher round.
A highly technical write-up about peeling back Themida’s famous software armor somehow sparked a very simple reaction from the peanut gallery: wait, this works on a lot more than just Themida? That line, dropped by commenter homarp, became the unofficial crowd slogan. The article’s big flex is that the author isn’t relying on brittle “spot the pattern” tricks that break the second an anti-tamper company sneezes out an update. Instead, the method aims to work broadly across many code-hiding systems, which is exactly the kind of claim that makes reverse-engineering fans cheer and protector vendors sweat.
The mood in the discussion is equal parts impressed and mischievous. There’s not a huge flame war here, but there is a delicious undercurrent of “so the so-called impossible lock isn’t so impossible after all.” The strongest opinion by far is that the real headline isn’t one product getting cracked — it’s the suggestion that a whole class of code camouflage tools may be more vulnerable than they’d like to admit. That’s catnip for this crowd.
Then came the bonus chaos: not_a9 casually tossed in a follow-up video featuring an even stronger obfuscator, basically turning the thread into a can-you-top-this challenge. It reads like the community is already demanding a sequel, popcorn in hand. For non-experts, the takeaway is simple: a digital disguise that’s supposed to make programs impossible to understand may be getting a lot less magical, and the comments are loving every minute of it.
Key Points
- •The article presents a devirtualization method for Themida and CodeVirtualizer that it says can be adapted to many VM-based obfuscators with minor changes.
- •It identifies Themida’s support for nested virtualization and its storage of VM context and virtual stack inside the binary as key architectural traits.
- •The author argues that pattern matching VM handlers to x86 instructions is fragile and does not scale across protector changes and versions.
- •The proposed approach relies on guided symbolic evaluation, lifting instructions into an intermediate representation and resolving control flow through optimization and concretization.
- •The article describes BLARE2 as the primary lifting and recompilation engine and also names Triton and LLVM-based tools such as Remill as viable alternatives for much of the workflow.
