Spy investigator exposes Russian Signal hackers

A spyware investigator, Donncha Ó Cearbhaill, uncovered a sophisticated phishing campaign by Russian government hackers targeting Signal users. The attackers impersonated Signal support, warning of suspicious activity and attempting to trick users into revealing verification codes to gain account access. Ó Cearbhaill, who was himself targeted, identified the campaign as 'ApocalypseZ,' an automated system used to compromise over 13,500 individuals, including journalists and politicians. This operation aligns with previous warnings from cybersecurity agencies about Russian state-sponsored hacking efforts. Ó Cearbhaill advises users to enable Signal's Registration Lock feature to prevent unauthorized account access.
