Death by a thousand PaperCuts, China's APT41 uses new tricks to skirt EDR, and a pair of no-patch vulnerabilities take the front page in this weeks newsletter:

The #PaperCut vulnerability continues to garner interest, with Iran's Mint SandStorm (formerly #PHOSPHORUS) and Mango SandStorm (formerly #MERCURY) seen using it opportunistically. A completely new exploit chain demo'd by Vulncheck researchers highlights the limitations of detection rules for assurances, and why patching is a must.
Earth Longzhi - a subset of the Chinese #APT41 Threat Group - has emerged after months in the shadows with new techniques seen in recent campaigns. Using Windows #Defender to side-load malware; the BYOVD technique to kill #EDR processes, and a newly discovered technique called "stack rumbling" to ensure they can't recover - this one is definitely one to check out.
Fortinet have warned of a recent wave of exploitation of a 5-year-old vulnerability with no patches being exploited en masse in late April, while #Cisco reveal a CVSS 9.8 vulnerability they have no plans to patch in their End-of-Support #VoIP phone adapters.
There's a bunch of great write-ups for those in the #redteam, looking at bypassing WAF protections by running tools like SQLMap over #Tor, how to minimise the size of your #XSS payloads, and highlighting a bunch of lab/ctf-style environments to cut your teeth on Azure, AWS, Kubernetes, and more.
The #blueteam can brush up on commonly abused misconfigurations in Active Directory, #AzureAD, and #Microsoft365, as well as some excellent tips on hunting the Open Source Posh, Deimos, and Havoc C2 frameworks using #Shodan and #Censys.
Elastic Labs have also outdone themselves last week, releasing a suite of tools to decrypt, decompress, recompile, extract and/or parse various malware payloads distributed in recent #IcedID campaigns.
There's lots to dig through before starting your work week, so get started here:
