Chinese hacking teams have been blamed by Western intelligence agencies and cybersecurity groups for digital intrusion campaigns across the world, targeting everything from government and military organisations to corporations and media groups.
Cybersecurity firms believe many of those groups are backed by China's government.
China's authorities have consistently denied any form of state-sponsored hacking, saying China itself is a frequent target of cyberattacks. Beijing has called the U.S. "the empire of hacking."
Some of the Chinese hacking teams recently identified are:
STORM-0558
Chinese hackers have since May secretly accessed email accounts at around 25 organisations, including U.S. government agencies, Microsoft and U.S. officials have said.
These include the accounts of U.S. Commerce Secretary Gina Raimondo and, according to a Wall Street Journal report on Thursday, U.S. envoy to China Nicholas Burns and Daniel Kritenbrink, the assistant secretary of state for East Asia.
Microsoft said a China-based actor, which it nicknamed Storm-0558, misappropriated one of its digital keys and used a flaw in its code to steal emails.
China's embassy in Washington said in a statement that identifying the source of cyber attacks was complex and warned against "groundless speculations and allegations."
'VOLT TYPHOON'
Western intelligence agencies and Microsoft said on May 24 that Volt Typhoon, a group they described as state-sponsored, had been spying on a range of U.S. critical infrastructure organisations, from telecommunications to transportation hubs.
They described the attacks in 2023 as one of the largest known Chinese cyber-espionage campaigns against American critical infrastructure.
China's foreign ministry rejected the claims.
'BACKDOORDIPLOMACY'
A Reuters report in May identified BackdoorDiplomacy as being behind a widespread series of digital intrusions over several years against key Kenyan ministries and state institutions. The Chinese authorities said it was not aware of such hacking and described the accusations as baseless.
Palo Alto Networks, a U.S. cybersecurity firm, said its research showed BackdoorDiplomacy had links to the Chinese state and was part of the APT15 hacking group.
APT 41
Chinese hacking team APT 41, which is also known as Wintti, Double Dragon and Amoeba, has conducted a mix of government-backed cyber intrusions and financially motivated data breaches, according to U.S.-based cybersecurity firms FireEye and Mandiant.
The U.S secret service said the team had stolen U.S. COVID-19 relief benefits worth tens of millions of dollars between 2020 and 2022.
Taiwan-based cybersecurity firm TeamT5 said the group had targeted government, telecoms and media victims in Japan, Taiwan, South Korea, the United States and Hong Kong.
APT 41 was named by the U.S Department Justice in September 2020 in relation to charges brought against seven hackers for allegedly compromising more than 100 companies around the world.
The Chinese authorities have described such reports as "groundless accusations."
APT 27
Western intelligence agencies and cybersecurity researchers say Chinese hacking team APT 27 is sponsored by the state and has launched multiple attacks on Western and Taiwanese government agencies.
APT 27 claimed responsibility for cyberattacks against Taiwan in 2022 during a visit by then U.S House of Representatives Speaker Nancy Pelosi, saying it acted as a protest because Pelosi defied China's warnings not to visit.
Cybersecurity firm Mandiant said last year the group compromised the computer networks of at least six U.S. state governments between May 2021 and February 2022, while the German authorities named blamed it for attacks against German pharmaceutical, technology and other companies.
