A cybercrime group with links to the RansomHub ransomware has been observed using a new tool designed to terminate endpoint detection and response (EDR) software on compromised hosts, joining the likes of other similar programs like AuKill (aka AvNeutralizer) and Terminator. The EDR-killing utility has been dubbed EDRKillShifter by cybersecurity company Sophos, which discovered the tool in

A researcher used two Windows vulnerabilities to perform downgrade attacks. These flaws have now been patched by Microsoft

### Summary An arbitrary file write vulnerability exists in the webcrack module when processing specifically crafted malicious code on Windows systems. This vulnerability is triggered when using the unpack bundles feature in conjunction with the saving feature. If a module name includes a path traversal sequence with Windows path separators, an attacker can exploit this to overwrite files on the host system. ### Details Source: [packages/webcrack/src/unpack/bundle.ts#L79](https://github.com/j4k0xb/webcrack/blob/241f9469e6401f3dabc6373233d85a5e76966b54/packages/webcrack/src/unpack/bundle.ts#L79) ```ts import { posix } from 'node:path'; import type { Module } from './module'; // eslint-disable-next-line @typescript-eslint/unbound-method const { dirname, join, normalize } = posix; /* ... snip ... */ const modulePath = normalize(join(path, module.path)); if (!modulePath.startsWith(path)) { throw new Error(`detected path traversal: ${module.path}`); } await mkdir(dirname(modulePath...

An ongoing social engineering campaign with alleged links to the Black Basta ransomware group has been linked to "multiple intrusion attempts" with the goal of conducting credential theft and deploying a malware dropper called SystemBC. "The initial lure being utilized by the threat actors remains the same: an email bomb followed by an attempt to call impacted users and offer a fake solution,"

Eight of the vulnerabilities affect the license update feature for CLIPSP.SYS, a driver used to implement Client License System Policy on Windows 10 and 11.

In K7 Ultimate Security versions prior to 17.0.2019, the driver file (K7RKScan.sys - this version 15.1.0.7) allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of a null pointer dereference from IOCtl 0x222010 and 0x222014. At the same time, the drive is accessible to all users in the "Everyone" group.

CVE-2024-6768 is a vulnerability in the Common Log File System (CLFS.sys) driver of Windows, caused by improper validation of specified quantities in input data. This flaw leads to an unrecoverable inconsistency, triggering the KeBugCheckEx function and resulting in a Blue Screen of Death (BSoD). The issue affects all versions of Windows 10 and Windows 11, Windows Server 2016, Server 2019 and Server 2022 despite having all updates applied. This Proof of Concept (PoC) shows that by crafting specific values within a .BLF file, an unprivileged user can induce a system crash.
