Volt Typhoon and other Chinese groups accused of hacking the US and others

SINGAPORE, May 25 (Reuters) – 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

China’s foreign ministry described the reports as part of a U.S. disinformation campaign.


Palo Alto Networks, a U.S. cybersecurity firm, says its research showed BackdoorDiplomacy has links to the Chinese state and is part of the APT15 hacking group.

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.

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.
