Researchers at NinjaLabs discovered the attack. This sophisticated attack leverages a cryptographic bug, known as a side-channel attack, present in a tiny chip — the Infineon SLE78 — within the key. The process requires physical access to the key, disassembling it using solvents or a hot air gun, connecting the chip to $11,000 worth of equipment, and extracting private keys from the key.
