Binary Exploitation — memory corruption to remote code execution

What we did

Reverse-engineered a compiled network service, identified a use-after-free in its object-management logic, and turned it into arbitrary code execution against the remote target. The chain required controlling heap layout so a freed object was reallocated with attacker-controlled data, then redirecting a corrupted function pointer into a controlled sequence.

• Static and dynamic analysis of the binary to map allocation and free paths
• Heap grooming to place attacker data into a dangling reference
• Leak primitive to defeat ASLR, then control-flow hijack to code execution
• Remote, repeatable exploitation — not a local crash

Why it matters to a client

Most application testers stop at the web tier. Memory-corruption skill matters when your product ships a compiled component — an on-prem agent, a native service, an embedded device, or a parser handling untrusted input. The same instinct that turns a use-after-free into RCE is what finds the deep bug a scanner never sees.
