“Researchers and journalists have publicly documented such attacks against popular cloud services, including iMessage as well as Facebook Messenger, Gmail, Signal, and WhatsApp. Always update your messaging and cloud apps to the latest available versions, as they contain the most up-to-date security improvements. Some state-sponsored attacks require no interaction from you, and others rely on tricking you into clicking a malicious link or opening an attachment in an email, SMS, or other message. These attempts can be quite convincing, ranging from fake package tracking updates to custom-crafted, emotional appeals claiming a named family member is in danger,” it further read.
