Block CEO Jack Dorsey confirmed that Apple has removed the decentralized communications app Bitchat in accordance with China’s requirements because it violates China’s Cybersecurity Law. Bitchat uses Bluetooth and a mesh network for communication and does not rely on the internet, which is why it has been widely used in protests. The app can still be used in other countries, and the global download count has exceeded 3 million.

Resolv Labs destroyed 36.73 million USR tokens held by the hacker via a contract upgrade. Previously, the hacker had minted 80 million USR tokens through a vulnerability and sold them off. The project team has since burned about 46 million USR tokens, and the actual loss was $34 million.

A six-month intelligence operation preceded the $270 million exploit of Drift Protocol and was carried out by a North Korean state-affiliated group, according to a detailed incident update published by the team earlier on Sunday. The attackers first made contact around fall 2025 at a major crypto c

BTQ Technologies publishes a research paper assessing the physical costs of quantum computing in Bitcoin mining, emphasizing that Bitcoin’s main risk comes from vulnerabilities in cryptographic signatures rather than quantum mining. The study proposes an open-source resource estimation model that covers key computational steps.

A decentralized perpetual contract trading platform Denaria announced that its smart contract was attacked, resulting in a loss of about $165k. The team is investigating with the auditors and has suspended the user interface while preparing a refund process. Denaria hopes to avoid legal action by inviting the attacker to contact them through a bounty program.

XRP Ledger validator Vet warns the XRP community after a social engineering scam drained $280 million from Solana's Drift Protocol, highlighting the need for caution and vigilance among builders in light of increasing crypto vulnerabilities.

Attorney Ariel Givner said that the 280M-dollar attack incident involving the Drift Protocol, which resulted from failing to follow basic security procedures, could amount to civil negligence. The attacker, after 6 months of planning, used a trusting relationship to steal the developers’ devices; there is already a class-action lawsuit advertisement targeting Drift circulating.

Crypto platforms — and investors — have long suffered from hacker attacks and exploits. Now, artificial intelligence (AI) is making that threat even worse. That’s the view of Charles Guillemet, chief technology officer at crypto wallet provider Ledger, who said the economics of cybersecurity are

On April 1, the Drift Protocol on the Solana chain was attacked by hackers, resulting in losses of about $285 million and a sharp drop in TVL. The investigation found that the attackers carried out a social engineering infiltration lasting 6 months, using Durable Nonce to bypass multiple signatures, highlighting the threat that nation-state hackers pose to DeFi and raising questions about Circle’s response speed.

A court in Qinzhou District, Tianshui City, Gansu Province, is trying a virtual-currency money-laundering case. The defendant used a part-time “high-paying errands” job to withdraw more than 390k yuan and, with knowledge of what was going on, exchange it for virtual currency, earning a profit of 21.5k yuan. The court sentenced him to two years and four months in prison and fined him. The judge reminded the public to stay alert to related activities in order to prevent them from fueling crime.

Google's Quantum AI team said earlier this week that a future quantum computer could derive a bitcoin private key from a public key in roughly nine minutes. The number ricocheted across social media and spooked markets. But, what does it actually mean in practice? Let's start with how bitcoin

Gate News update. According to a message on the X platform, the initial investigation into the Drift hacker attack indicates that members of the project team had previously been approached in person by North Korean intermediaries at a cryptocurrency industry conference. The investigation also reveals that there was in-person contact between the attacker and the team members.

CertiK reports that in March 2026 there were 46 security incidents, with total losses of approximately $39.8 million, the highest monthly number since November 2024. Security incidents increased in the fourth quarter of 2025 and the first quarter of 2026, and the occurrence of code vulnerability exploits is linked to the rise of artificial intelligence.

On-chain investigator ZachXBT published a report stating that since 2022, Circle has repeatedly failed to properly carry out compliance in multiple incidents involving illegal funds, with amounts totaling more than $420 million. The report notes that in several security incidents, Circle did not freeze suspicious accounts in a timely manner, leading to severe losses.

The Japan Financial Services Agency has issued “Policy Guidelines for Strengthening Cybersecurity for Crypto Asset Exchange Businesses and Related Entities,” with the aim of strengthening investor asset protection. It proposes a three-layer security framework to address the new landscape of cyberattacks. In subsequent plans, it will conduct penetration testing on major operators and revise the guidance to raise security standards.
