Researchers at Citizen Lab have exposed a sophisticated Israeli-developed cyberespionage method called AdFection, which bypasses traditional infection routes by exploiting vulnerabilities in web ads rather than requiring direct victim interaction. The technique allows attackers to compromise devices simply through exposure to infected advertisements, marking a shift in how digital surveillance tools operate. Unlike phishing scams or malicious downloads, this method spreads passively, raising concerns over its potential for widespread, undetected infiltration. Security experts warn the discovery highlights growing risks in online advertising ecosystems as a new vector for cyber threats.
