President Barack Obama negotiated the reduction in Chinese hacking in 2015, but the attacks ramped up again as the Trump administration pursued a trade war with Beijing, the report said. Adam Meyers, vice president of intelligence at Crowdstrike, told Bloomberg, “By 2017 they started coming back and throughout 2018 they were back in full force.”

Separately, China’s government accused the United States of trying to stoke unfounded cybersecurity fears about the Chinese mobile network, which could stymie the growth of Chinese businesses. Geng Shuang, a spokesman for the Chinese foreign ministry, said there is an effort in Washington “to fabricate an excuse for suppressing the legitimate development” of Chinese industry, as CNBC reports. Shuang called this “hypocritical, immoral and unfair bullying.”

British intelligence recently concluded that it could handle the cybersecurity risks posed by allowing Chinese tech company Huawei to build next-generation 5G networks, according to The Financial Times. The move by the United Kingdom could be influential, as it is close allies with the United States, which has been pressing for countries to ban the use of Huawei tech in their 5G rollouts. But a Forbes blogger points out the information leak to the FT may have been timed to soothe U.K.-China tensions in hopes of a post-Brexit trade deal.

Germany, too, recently rebuked the United States on Huawei. Several Germany officials said Berlin is planning to permit the Chinese company’s participation in 5G construction, The Wall Street Journal reports.

Meanwhile, Australia’s major political parties have been hit by a major cyber attack just months before an election. The government said cyber security experts suspected a foreign power was behind the attack. According to the Australian Associated Press, China has responded to suspicions about its possible role in the attack as “irresponsible” and “baseless.”
