4. Binance warns that there is a cross-application file reading vulnerability in iOS, and mnemonic phrases and private keys may be at risk of being leaked.

Binance issued a security warning stating that there is a vulnerability called worse_query in the iOS system, affecting iOS versions 26.7.1, 27.0.1, and 27.2. This vulnerability may allow malicious applications to bypass the system isolation mechanism and read local files of other applications, resulting in the risk of leakage of wallet mnemonics, private keys and login credentials stored in related files. Binance emphasized that this is a system-level issue that affects the entire iOS ecosystem and is not a vulnerability unique to Binance. The platform recommends that users delete applications installed through untrusted sources and update iOS and applications to the latest official version; if they suspect that their device has been compromised, they should use a secure device to create a new wallet and transfer assets, and reset all login sessions.

5. Canada plans to ban federal financial institutions from directly issuing stablecoins. The new regulations will take effect in 2027.

The Canadian government proposed in the 2026 federal budget that it plans to amend the Banking Act, the Trust and Loan Company Act and the Insurance Company Act to prohibit federally regulated financial institutions from directly issuing stablecoins and require them to carry out issuance activities through non-financial institution subsidiaries regulated by the Stablecoin Act.

Canada’s Stablecoin Act received Royal Assent in March this year, and relevant implementation details are still being solicited for comments and are expected to officially take effect in 2027.

6. The U.S. IRS sends tax reminder letters to crypto users on a large scale

The U.S. Internal Revenue Service (IRS) has recently significantly increased the number of Letter 6174 tax reminder letters sent to cryptocurrency investors, urging recipients to check whether past crypto asset transactions have been properly reported. Donnelly estimated that the IRS sends about 10,000 letters per month, but that scale has not been officially confirmed. It is worth noting that David Schwartz, the former CTO of Ripple, also said that he recently received the letter, but thought it was just a reminder to taxpayers to comply with the law, so he threw it directly into the trash can. According to official information from the IRS, Letter 6174 is a voluntary compliance reminder used since 2019. It is not a formal tax audit or violation of law. It usually does not require a direct response, but the recipient should still check his or her declaration status.
