Overview

• Attackers who scan the WhatsApp QR code can link a computer or tablet to an account and read chats remotely without the user noticing.
• Many users remain unaware that an unfamiliar device is connected, so regular checks of the “Linked devices” list are advised.
• Phishing and social‑engineering schemes target WhatsApp verification codes, enabling account takeover and access to message histories.
• Spyware installed from untrusted sources can run in the background, with warning signs including high data use, rapid battery drain and sluggish performance.
• HNA also flags a developing warning that iPhone users are being told to install a mandatory WhatsApp update to address another spying risk.
