As in other Chinese cyberattacks, these APT campaigns exploited flaws in Microsoft Exchange servers. The researchers uncovered several previously unidentified cyberattack campaigns infiltrating major providers and evading detection since at least 2017, Cybereason says. Researchers identified three clusters of attacks associated with the campaign that it attributed to the Chinese APTs Soft Cell, Naikon and Threat Group-3390. The firm says overlaps in the attackers tactics, techniques and procedures suggest a connection between the groups.
