Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is triggered by processing maliciously crafted web content via WebKit; monitor for unexpected crashes or arbitrary code execution originating from WebKit-based browsers/renderers (Safari, WebKitGTK) ↗
- →The root cause is a use-after-free in WebKit memory management; detection should focus on heap UAF exploitation patterns in WebKit renderer processes ↗
- →On Linux/Debian systems, flag unpatched webkitgtk versions below 2.38.3-1 as vulnerable ↗
- →Red Hat: webkitgtk and webkitgtk3 packages on RHEL 6/7 are out of support scope and remain unpatched; treat any deployment as permanently vulnerable ↗
- →Attack vector is network-based; an attacker with network access can deliver specially crafted web content to trigger the flaw — monitor for anomalous inbound web content delivery to WebKit consumers ↗
- ·Fixed in Apple platforms: Safari 16.2, tvOS 16.2, macOS Ventura 13.1, iOS 16.2, iPadOS 16.2, watchOS 9.2 — detections targeting unpatched versions should scope to anything below these versions ↗
- ·Debian fix is webkitgtk >= 2.38.3-1 across all tracked suites (bookworm, bullseye, forky, sid, trixie); earlier versions remain vulnerable ↗

CVE-2022-46699 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.

7 Ways Threat Actors Deliver macOS Malware in the Enterprise
Our 2022 review of macOS malware revealed that the threats faced by businesses and users running macOS endpoints included an increase in backdoors and cross-platform attack frameworks. Threats like CrateDepression and PyMafka used typosquatting attacks against package repositories to infect users, while ChromeLoader and others like oRAT leveraged malvertising as an infection vector.
However, the infection vector used by many other macOS threats remains unknown. SysJoker, OSX.Gimmick, CloudMensis, Alchimist and the Lazarus-attributed Operation In(ter)ception are just some of those for which researchers still do not know how victims were initially compromised. In these and other cases, researchers happened across the malware either in post-infection analyses or by discovering the samples on
