Lido maintains operational stability, emphasizing the protocol remains fully secure due to its 5‑of‑9 oracle consensus model, which limits the impact of any single oracle compromise

Quotes that support claims

Though the attacker was able to drain the oracle address's ETH balance (which was purposely held at a low level, Chorus One said), the attack didn't threaten Lido's operations, as its protocol reporting oracles require a 5-of-9 consensus.

Lido’s oracles operate with a 5-out-of-9 quorum, meaning even if one fails or is compromised, the rest can keep things running safely.
