A new phishing kit, dubbed “Bulletproof Redirector,” uses compromised legitimate websites and hidden directories to evade secure email gateways and facilitate credential theft^[4].
Attackers are increasingly exploiting supply chain weaknesses, as seen in the BdThemes and Metabase incidents, to compromise downstream targets^[8]^[16]^[27]^[40].
Security researchers have demonstrated that passkey-based authentication can be undermined through attacks on synchronization and device trust mechanisms^[13]^[20].
Increased scanning activity targeting Solana blockchain endpoints has been observed, indicating heightened interest in exploiting crypto-related infrastructure^[33].

Regulatory or Policy Developments Affecting the Security Industry

Outdated cybercrime laws are putting security researchers at risk, prompting calls for legal reforms to protect ethical hackers and good-faith security research^[30].
Microsoft Edge is dropping support for Manifest V2, which will impact popular privacy tools that rely on older extension technology, potentially reducing user privacy protections^[46].
Mozilla has issued a new Firefox GPG signing key after the previous subkey was inadvertently exposed on GitHub, requiring a key revocation^[34].
