SwissBorg has just suffered one of the most striking hacks of the year. In a few hours, 193,000 SOL, or 41 million dollars, were siphoned off via a flaw in the Kiln validator API, a provider responsible for staking on Solana. It was not SwissBorg's infrastructure that failed, but that of a third-party partner. The incident reignites the debate on the security of external integrations in a sector where the slightest failure can be enough to bring down the entire chain.
