A hacker exploited two software bugs to create 46 billion fake BTC tokens on the Symbiosis DeFi bridge, turning just 25 cents of Bitcoin into an unbacked supply. The preliminary losses are estimated at 9.97 BTC, highlighting the risks of DeFi vulnerabilities.
MIT professor Muriel Médard contends that existing mathematical tools, not quantum computers, are the key to making blockchains quantum-safe. She believes classic cryptography can be adapted to protect digital assets from future threats. This approach could save the industry billions in potential losses.
Blockstream is demanding that hackers return the remaining Bitcoin stolen from its Liquid sidechain. The hackers initially took over 4,000 BTC but have returned some, claiming a reward for their efforts. Blockstream is not willing to negotiate, insisting on the full return of the stolen funds.
Revolut accidentally shared Bitcoin transaction histories, passports, and other personal data after treating a fraudulent government request as legitimate. The breach affected a limited number of users, but no customer funds were lost. This incident highlights the risks of phishing and the importance of verifying official requests.
Blockstream is refusing to pay a ransom for 598.5 BTC ($47 million) stolen in the Liquid hack, calling it theft. They plan to involve law enforcement if the funds aren't returned.
Mexican prosecutors allege that the murder of Camilo Séptimo keyboardist Jonathan Meléndez, his wife, and their two children was motivated by the search for a Bitcoin cold wallet the suspects believed held millions. The case underscores the real-world dangers of crypto asset ownership.
Hackers stole $320 million in Bitcoin from the Liquid Network, then returned $270 million, claiming they were exposing security flaws. This follows a pattern of high-profile crypto exploits in 2026, including attacks on Polymarket and other exchanges.
AI tools are increasingly finding bugs in Bitcoin’s layer-2 infrastructure, including Coldcard, Lightning, and Liquid. This shift highlights how AI is changing the economics of security research in crypto. Recent incidents underscore the need for heightened vigilance as these technologies evolve.
A self-described white-hat party returned 3,400 BTC to Liquid Network's federation wallet on Monday after Blockstream said bridge nodes were patched. About 598.5 BTC, worth nearly $47 million, remains at the holder address.
The Ethereum Foundation has set a 2029 deadline to make the network quantum-resistant, aiming to protect against potential threats from future quantum computers. Upcoming upgrades, including the Hegotá upgrade, will be evaluated against this timeline.
The hacker responsible for the Coldcard thefts has moved $7.7 million in Bitcoin, representing 45% of the stolen funds from the third wave of attacks. This latest movement highlights the ongoing risk for victims of the breach.
A Hacken security report warns that Tether's USDT stablecoin, worth $91 billion, could be at risk if hackers gain control of two critical security keys. The report combines Wall Street financial auditing with Web3 code reviews to evaluate both off-chain reserves and on-chain security.
Hackers stole $320 million in Bitcoin from the Liquid Network but returned $270 million after Blockstream patched the vulnerability. Nearly 600 BTC, worth about $50 million, remains outstanding.
Liquid Network, a Bitcoin sidechain, lost nearly all of its Bitcoin reserve in a single incident on September 6. Around 4,000 BTC, worth approximately $320 million, was transferred out of the Liquid Federation wallet. The incident has raised significant concerns about the security and stability of the network.
The G7 is urging organizations to adopt post-quantum security measures to protect against the future threat of quantum computing. This warning comes as the crypto industry explores potential fixes to safeguard digital assets.
Trezor has disclosed that an additional 67,000 US customers' data was exposed due to its shipping partner, ShipMonk, failing to erase customer records. This follows an earlier breach, raising concerns about data security for Trezor users.
Tether-backed Orionx is shutting down permanently after an audit revealed a $7 million gap in customer assets. The audit found that funds were moved to wallets outside Orionx's custody, raising concerns about asset security.
Several Chrome extensions have been found stealing cryptocurrency and browser data from unsuspecting users. This highlights the growing threat of malicious browser extensions. Users should be cautious and verify extensions before installing them.
