Personal friends of employees at Google, Adobe and other companies were targeted by hackers in a string of recently disclosed cyberattacks, raising privacy concerns and pointing to a highly sophisticated operation, security experts said.
Cybersecurity experts analysing the attacks said the hackers spied on individuals and used other sophisticated techniques, making them extremely difficult to stop. The disclosures come amid renewed alarm over cybersecurity after Google said it had been the target of a series of cyberattacks from China.
