On March 21, 2026, Ledger CTO Charles Guillemet issued a security alert regarding a critical update for the Chrome web browser, addressing 26 vulnerabilities, including 4 critical and 22 high severity issues. These vulnerabilities, primarily related to memory management errors, could allow attackers to execute malicious code remotely by luring users to compromised webpages. Additionally, Binance warned of a critical iOS exploit chain named 'DarkSword' affecting iOS versions 18.4 to 18.7, which could extract sensitive data without user interaction. Both alerts emphasize the need for users to update their systems immediately to mitigate risks.
