The hacking tools, techniques and procedures used in this attack were similar to the previous attacks attributed to Chinese hackers.
“Private investigators looking into the breach have found hacking tools, techniques and procedures previously used in attacks attributed to Chinese hackers, said three sources who were not authorized to discuss the company’s private probe into the attack.” said in the post published by Reuter’s
Sources also suggest the potential goal of hackers behind the campaign was to gather information and not for financial gain.
They also warned that since some of the tool used in the attack are already available online there is a possibility that some others may be behind the attack.
