{NEW} Chinese hackers are exploiting new SharePoint flaws—Microsoft links attacks to #APT27, #APT31 & Storm-2603.

They’re bypassing patches to steal MachineKeys via remote code execution.

The exploit chain is already in the wild. #CyberSecurity #CyberAttacks https://thehackernews.com/2025/07/microsoft-links-ongoing-sharepoint.html

"The Department of Justice has announced criminal charges against 12 Chinese government-linked hackers who are accused of hacking more than 100 American organizations, including the U.S. Treasury, over the course of a decade.

The charged individuals all played a “key role” in China’s hacker-for-hire ecosystem, a senior DOJ official said on a background call with reporters, including TechCrunch, on Wednesday. The official added that those charged, which includes contract hackers and Chinese law enforcement officials, targeted organizations in the U.S. and worldwide for the purposes of “suppressing free speech and religious freedoms.”

The DOJ also confirmed that two of the indicted individuals are linked to the China government-backed hacking group APT27, or Silk Typhoon."

Last week's reporting gave a great insight into the level of innovation going on in the cyber crime ecosystem - C2 over MQTT, cryters delivering payloads over SQL connections, and UEFI bootkits that bypass Window's Secure Boot! We've pulled it all together, just for you:

The BlackLotus #Bootkit has been upgraded to exploit a vulnerability in Microsoft's Secure Boot Mechanism, allowing it to persist on fully patched Windows 11 systems. This is enabled in no small part by the failure to update the UEFI revocation list, which allowed the bootkit author to simply load and exploit the vulnerable UEFI components on target systems.

Australia's cyber security laws were "bloody useless" in helping mitigate the Optus and Medibank breaches of 2022, according to the government's Home Affairs Minister. A new "national cyber office", reforms to Critical Infrastructure security laws, and a new Cyber Security Act are all on the table for discussion.

zScaler analysts have picked up on the Snip3 crypter, a Crypter-as-a-Sevice offering which uses multiple obfuscated stages; an AMSI Bypass, and SQL queries to circumvent security controls.

Sysdig share insights from a sophisticated #AWS-centric campaign; ESET have uncovered a new backdoor used by China's Mustang Panda (#APT27) which implements C2 over MQTT, and Team Cymru have again picked apart #IcedID's infrastructure to identify key TTPs.

Some interesting supply chain vulnerabilities this week, with bugs found in the ZK web app framework and Trusted Platform Module (TPM) having the potential to affect an untold number of applications and devices.

#Redteam members will get a kick out of DroppedConnection - a PoC that mimics Cisco AnyConnect VPN to siphon credentials and serve up malware to unwitting victims.

The #blueteam can look forward to some tips for GCP DFIR, bypassing malware geo-fencing, and tracking cyber criminal infrastructure.

Catch all this and much more in this week's newsletter:
