Binance launches withdrawal lock feature to address risks of "wrench attacks" and other offline coercion

According to market news, Binance has announced the launch of a user-controlled "Withdraw Protection" feature, aimed at preventing offline coercion attacks (commonly known as "wrench attacks") against cryptocurrency holders. This feature allows users to actively lock their account withdrawal permissions for 1 to 7 days and provides a stricter "lock mode," which cannot be lifted early during the set period.Binance stated that this locking mechanism cannot be overridden by platform customer service but is controlled by internal policy, not an on-chain cryptographic lock. Binance's Chief Security Officer, Jimmy Su, indicated that this move stems from the risk trends observed on the platform, including cases where some users in high-risk areas have been forced to transfer funds. By setting a withdrawal delay, it can buy users time to respond and recover in extreme situations.Data shows that incidents of offline coercion against cryptocurrency users are significantly rising in 2025, with related attacks often bypassing traditional account security mechanisms, as the actions are completed by the users themselves under pressure. Industry insiders believe that the time-lock mechanism can change this risk model to some extent. Binance emphasizes that this feature does not affect law enforcement agencies' ability to act in accordance with the law, while also advising users to strengthen API key management and privacy protection to reduce the risk of being targeted.

The South Korean cryptocurrency industry collectively opposes the new anti-money laundering regulations, planning to require all overseas transfers of over 10 million won to be reported as suspicious transactions

According to Cointelegraph, the South Korean crypto industry group DAXA (Digital Asset Exchange Alliance), representing 27 registered virtual asset service providers (VASP), has submitted objections to the Financial Services Commission (FSC) and the Financial Intelligence Unit (FIU) regarding the proposed amendments to the implementation order of the Specific Financial Information Act.The new regulations aim to require domestic VASPs to report any virtual asset transfers with foreign VASPs as suspicious transaction reports (STR) if the amount reaches 10 million won (approximately $6,800), regardless of the risk level. DAXA warned that this would cause the annual reporting volume of South Korea's five major trading platforms (Upbit, Bithumb, Coinone, Korbit, Gopax) to surge from about 63,000 last year to over 5.4 million, making compliance practically impossible.The industry also opposes the proposed requirement to verify the accuracy of customer information, arguing that the subordinate rules impose obligations not clearly defined by law. This industry backlash comes as exchanges face sanctions from financial regulators in court. On April 9, the court ruled to lift part of the business suspension against Upbit operator Dunamu, but the regulators have appealed. On April 30, the court suspended the six-month partial business suspension against Bithumb. Coinone also received a temporary stay of execution.The public consultation period for the new regulations ends on May 11, and it is expected to be finalized in July after regulatory and legal reviews. This highlights the tension between South Korea's tightening of crypto anti-money laundering regulations and the industry's concerns about excessive compliance burdens.
