Top features

UniqBuildz is more than just obfuscation and distribution.
Take a look at the top features we offer.

Randomized builds

Every download is a newly obfuscated binary with entirely randomized mutation applied. This will render any signature invalid.

Control Flow Graph Flattening

Rearrange the program structure, all basic blocks are split and put into an infinite loop and the program flow is controlled by a switch and a variable.

Instruction substitution

Replace standard binary operators (like addition, subtraction or boolean operators) by functionally equivalent, but more complicated sequences of instructions. When several equivalent instructions sequence are available, one is chosen at random.

Entry-point obfuscation

For .exe we will generate a custom entry point that will contain an opaque that will jump to the real entry point of the executable

LEA obfuscation

LEA instruction is mutated to four instructions that will load a different location into the target register and apply math operations to it afterward. This prevents being able to xref data or functions

Anti-Disassembly

Instruction starting with FF will be mangled without any side effects. This will throw off disassemblers and decompilers.
