According to Wu Blockchain, Threshold Network announced that on May 18 at 18:04, a malicious actor attempted to mint tBTC without depositing the underlying BTC. However, the attack was unsuccessful, no invalid tBTC was issued, and user funds were not at risk. As a precaution, and in light of the recent increase in malicious activity within the crypto ecosystem, Threshold has temporarily paused Optimistic Minting. Currently, tBTC minting will be processed through the sweeping mechanism, extending the typical minting time from approximately 1.5 hours to about 6 to 7 hours. https://(wublock123.com)/news/threshold-malicious-attempted-btc-minting-failed-61358
