Dark Reading
A threat actor resembling APT41 performed "AppDomainManager Injection," which is like DLL sideloading, but arguably easier and stealthier.
The Hacker News
Cybersecurity researchers have shed light on a novel Linux kernel exploitation technique dubbed SLUBStick that could be exploited to elevate a limited heap vulnerability to an arbitrary memory read-and-write primitive. "Initially, it exploits a timing side-channel of the allocator to perform a cross-cache attack reliably," a group of academics from the Graz University of Technology said [PDF]. "

Protections like Windows Smart App Control are useful but susceptible to attacks that allow threat actors initial access to an environment without triggering any alerts.
The Hacker News
Over a million domains are susceptible to takeover by malicious actors by means of what has been called a Sitting Ducks attack. The powerful attack vector, which exploits weaknesses in the domain name system (DNS), is being exploited by over a dozen Russian-nexus cybercriminal actors to stealthily hijack domains, a joint analysis published by Infoblox and Eclypsium has revealed. "In a Sitting

Threat actors are exploiting a novel attack technique in the wild that leverages specially crafted management saved console (MSC) files to gain full code execution using Microsoft Management Console (MMC) and evade security defenses. Elastic Security Labs has codenamed the approach GrimResource after identifying an artifact ("sccm-updater.msc") that was uploaded to the VirusTotal malware
The Hacker News
The security risks posed by the Pickle format have once again come to the fore with the discovery of a new "hybrid machine learning (ML) model exploitation technique" dubbed Sleepy Pickle. The attack method, per Trail of Bits, weaponizes the ubiquitous format used to package and distribute machine learning (ML) models to corrupt the model itself, posing a severe supply chain risk to an

The threat actors behind the CatDDoS malware botnet have exploited over 80 known security flaws in various software over the past three months to infiltrate vulnerable devices and co-opt them into a botnet for conducting distributed denial-of-service (DDoS) attacks. "CatDDoS-related gangs' samples have used a large number of known vulnerabilities to deliver samples," the QiAnXin XLab team

Security agencies in the United States have issued a new warning about the Black Basta ransomware group, in the wake of a high-profile attack against the healthcare giant Ascension. The cyber attack last week forced the Ascension computer systems offline, and caused some hospital emergency departments to turn away ambulances "in order to ensure emergency cases are triaged immediately." Read more in my article on the Exponential-e blog.

A new DNS threat actor dubbed Savvy Seahorse is leveraging sophisticated techniques to entice targets into fake investment platforms and steal funds. “Savvy Seahorse is a DNS threat actor who convinces victims to create accounts on fake investment platforms, make deposits to a personal account, and then transfers those deposits to a bank in Russia,” Infoblox said in a report
The Hacker News
A new collection of eight process injection techniques, collectively dubbed PoolParty, could be exploited to achieve code execution in Windows systems while evading endpoint detection and response (EDR) systems. SafeBreach researcher Alon Leviev said the methods are "capable of working across all processes without any limitations, making them more flexible than existing process
