Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability resides in the JavaScriptCore (JIT compiler) component of WebKit/WebKitGTK; detection should focus on exploitation attempts via maliciously crafted web content targeting this engine ↗
- →Active in-the-wild exploitation confirmed on Intel-based Mac systems; prioritize detection/hunting on that platform ↗
- →On Red Hat Enterprise Linux 7, the JIT engine can be disabled as a mitigation by setting the JavaScriptCoreUseJIT environment variable to 0; presence of this env var set to 1 (or absent) on RHEL7 systems running WebKitGTK indicates exposure ↗
- →On RHEL7, gnome-shell can be exploited by a local network attacker without user interaction when WebKitGTK is present; monitor gnome-shell network activity and WebKitGTK process behaviour for anomalous code execution ↗
- →Packages that load WebKitGTK on RHEL7 and represent attack surface include: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi, and yelp; monitor these processes for unexpected child process spawning or memory anomalies ↗
- ·WebKitGTK JIT engine must be enabled for exploitation; RHEL 8 and 9 have it disabled by default and are not affected ↗
- ·Exploitation requires an attacker to trick a user into processing or loading malicious web content (except in gnome-shell on RHEL7, which is exploitable from the local network without user interaction) ↗

CVE-2024-44309 WebKitGTK vulnerabilities
Title: WebKitGTK vulnerabilities
Summary: Several security issues were fixed in WebKitGTK.
Several security issues were discovered in the WebKitGTK Web and JavaScript
engines. If a user were tricked into viewing a malicious website, a remote
attacker could exploit a variety of issues related to web browser security,
including cross-site scripting attacks, denial of service attacks, and
arbitrary code execution.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK, such as Epiphany, to make all the necessary changes.

## 25th November – Threat Intelligence Report
The Library of Congress, part of the US Capitol complex and home to the world’s largest media collection, was hacked by a foreign adversary, exposing email communications between Library staff and congressional offices from January to September 2024. The hack, described as sophisticated espionage, sought information on legislative inquiries but did not compromise House or Senate networks or the US Copyright Office.

CVE-2024-44308 [HIGH] Apple fixes two zero-days used in attacks on Intel-based Macs
## Apple fixes two zero-days used in attacks on Intel-based Macs
## Lawrence Abrams
The JavaScriptCore CVE-2024-44308 flaw allows attackers to achieve remote code execution through maliciously crafted web content. The other flaw, CVE-2024-44309, allows cross-site scripting (CSS) attacks.
The company says it addressed the security flaws in macOS Sequoia 15.1.1 .
As the same components are found in other Apple operating systems, it was also fixed in iOS 17.7.2 and iPadOS 17.7.2 , iOS 18.1.1 and iPadOS 18.1.1 , and visionOS 2.1.1 .
While Apple says both flaws were discovered by Clément Lecigne and Benoît Sevens of Google's Threat Analysis Group, the company has not provided further details on how they were exploited.
