In May, Microsoft and Western spy agencies said Chinese hackers had used “stealthy” malware to attack critical infrastructure on American military bases in Guam. Experts said it was one of the largest known cyber espionage campaigns against the US. China routinely denies involvement in hacking operations regardless of the available “evidence or context” . China-based hackers have gained access to the email accounts of around 25 organisations, including government agencies, Microsoft says. The software giant has not provided details of where the government agencies are based. Do you think that this are just mere allegations against China ?
