Hacken Finds Major Tether Key Security Vulnerability: Two Keys Control $9.1 Billion USDT
Security audit firm Hacken found that Tether has a major key security vulnerability. It reportedly takes only compromising two keys to control USDT valued at $9.1 billion. Although Tether also received an upgrade to its BlueChip rating, weaknesses in key management have raised market concerns. USDT is the cornerstone of liquidity in the crypto market, and the $9.1 billion figure represents the vast majority of its total market cap. If this vulnerability is exploited, the consequences would be catastrophic—far beyond any exchange hack incident in the past. The threshold of two keys may seem high, but it is not insurmountable for organized attackers. This risk exposure alone is enough to be unsettling. For traders, this is not an immediate threat, but a warning signal at the tail-risk level. The probability of short-term USDT de-pegging remains low, but investors should closely monitor on-chain redemption pressure, changes in USDT premiums, and Tether’s subsequent security upgrade actions. Looking into the mid to long term, stablecoin key management and audit transparency will likely face stricter scrutiny, and some funds may flow back to decentralized stablecoins.
Assets involved: USDT and the stablecoin sector as a whole
Slightly bearish: limited impact on near-term market pricing, but medium- to long-term risks cannot be ignored.
