UK parliamentary authorities are warning MPs and officials about a sharp rise in phishing attacks targeting their WhatsApp and Signal accounts, with Russian-based actors actively involved. The attacks involve fake messages from app support teams asking users to enter codes, click links, or scan QR codes, potentially giving hackers access to messages and contacts.

Despite new security measures introduced by the National Cyber Security Centre in October, attacks continue climbing. Parliament is now urging legislators to stop using commercial messaging apps for work and switch to Microsoft Teams instead.

This follows previous incidents, including a 2023 investigation into "Abigail" WhatsApp attacks and the identification of Russian intelligence group Star Blizzard targeting MPs since 2015.
