Chinese hackers tried to breach security at seven US firms since Xi and Obama signed cyber deal, security company says
Chinese-linked attackers have tried to breach systems at seven American companies in weeks since cyber deal was signed, says security firm

Hackers associated with the Chinese government have tried to penetrate at least seven US companies in the three weeks since Washington and Beijing agreed not to spy on each other for commercial reasons, according to a prominent American security firm.
CrowdStrike said software it placed at five US technology and two pharmaceutical companies had detected and rebuffed the attacks, which began on September 26. The day before, US President Barack Obama said he and President Xi Jinping had agreed that neither government would knowingly support cybertheft of corporate secrets to support domestic businesses.
The agreement stopped short of restricting spying to obtain government secrets, including those held by private contractors.
CrowdStrike co-founder Dmitri Alperovitch said he believed the hackers who attacked the companies were affiliated with the Chinese government based in part on the servers and software they used. The software included a program known as Derusbi, according to Alperovitch. Other analysts have said Derusbi has turned up in attacks on Virginia defence contractor VAE and health insurer Anthem.
Alperovitch said the hackers came from a variety of groups including one CrowdStrike had previously named Deep Panda.
The "primary benefits of the intrusion seem clearly aligned to facilitate theft of intellectual property and trade secrets, rather than to conduct traditional, national-security-related intelligence collection," the company said.
