Meta says it has warned U.S. presidential campaigns to be wary after it discovered an Iran-linked hacking attempt using the WhatsApp messaging service. The announcement is the latest from a tech giant of hacking threats ahead of the November election between Vice President Kamala Harris and former president Donald Trump, after Google and Microsoft earlier uncovered similar attempts attributed to Iran.WhatsApp accounts linked to an Iranian "threat actor" sent messages pretending to be technical support for AOL, Google, Yahoo, or Microsoft, according to a Meta blog post. Accounts involved in what appeared to be "social engineering" were blocked, Meta said.
