The prolific China-linked nation-state actor known as APT41 has been linked to two previously undocumented strains of Android spyware called WyrmSpy and DragonEgg. "Known for its exploitation of web-facing applications and infiltration of traditional endpoint devices, an established threat actor like APT 41 including mobile in its arsenal of malware shows how mobile endpoints are high-value targets with coveted corporate and personal data," Lookout said in a report shared with The Hacker News.
US commerce secretary Gina Raimondo and other State and Commerce Department officials were reportedly among the victims of a China-based group's attack on Microsoft's hosted email services. The US Cybersecurity and Infrastructure Security Agency and the FBI issued a joint advisory detailing how a Federal Civilian Executive Branch agency was tipped off when it observed MailItemsAccessed events with an unexpected ClientAppID and AppID in Microsoft 365 Audit Logs - as the AppId did not normally access mailbox items in that manner.
A Chinese hacking group has breached the email accounts of more than two dozen organizations worldwide, including U.S. and Western European government agencies, according to Microsoft. "Microsoft investigations determined that Storm-0558 gained access to customer email accounts using Outlook Web Access in Exchange Online and Outlook.com by forging authentication tokens to access user email," Microsoft said in a blog post published late Tuesday evening.
Microsoft on Tuesday revealed that it repelled a cyber attack staged by a Chinese nation-state actor targeting two dozen organizations, some of which include government agencies, in a cyber espionage campaign designed to acquire confidential data. "They focus on espionage, data theft, and credential access," Microsoft said.
Cybersecurity researchers have unearthed a novel rootkit signed by Microsoft that's engineered to communicate with an actor-controlled attack infrastructure. "This malicious actor originates from China and their main victims are the gaming sector in China," Trend Micro's Mahmoud Zohdy, Sherif Magdy, and Mohamed Fahmy said.
Sophisticated hackers have accessed email accounts of organizations and government agencies via authentication tokens they forged by using an acquired Microsoft account consumer signing key, the company has revealed on Tuesday. "The threat actor Microsoft links to this incident is an adversary based in China that Microsoft calls Storm-0558. We assess this adversary is focused on espionage, such as gaining access to email systems for intelligence collection."
Infosec outfit Checkpoint says it's spotted a Chinese actor targeting diplomatic facilities around Europe. Checkpoint has dubbed the campaign "SmugX" thanks to its use of HTML smuggling to deploy the PlugX remote access trojan.
A Chinese nation-state group has been observed targeting Foreign Affairs ministries and embassies in Europe using HTML smuggling techniques to deliver the PlugX remote access trojan on compromised systems. "The campaign uses new delivery methods to deploy a new variant of PlugX, an implant commonly associated with a wide variety of Chinese threat actors," Check Point said.
What is new is the extent to which the balloon was driven by US hardware, which unnamed sources told the Wall Street Journal was "Crammed" with off-the-shelf components that could have easily been purchased online. In February, US officials added six Chinese companies to its trade-restricting Entity List over their work with the Chinese government to develop high-altitude balloons like the one in question.
The newly discovered Chinese nation-state actor known as Volt Typhoon has been observed to be active in the wild since at least mid-2020, with the hacking crew linked to never-before-seen tradecraft to retain remote access to targets of interest. "The adversary consistently employed ManageEngine Self-service Plus exploits to gain initial access, followed by custom web shells for persistent access, and living-off-the-land techniques for lateral movement," the cybersecurity company said.
