- →Detect suspicious child processes spawned by Microsoft Office applications on Windows, which may indicate exploitation of CVE-2023-32046 or related vulnerabilities. ↗
- →The exploit requires a user to open a specially crafted file delivered via email or a malicious/compromised website. Monitor for Office applications opening files from untrusted locations and subsequently making network connections. ↗
- →The IP addresses associated with Storm-0978/RomCom activity are known to host TOR/VPN infrastructure. Monitor outbound connections to these IPs from Office processes. ↗
- ·The SHA-256 hashes and IP addresses listed are associated with the broader Storm-0978/RomCom campaign (primarily CVE-2023-36884). They are reported alongside CVE-2023-32046 as related IOCs but may not be exclusively tied to CVE-2023-32046 exploitation. ↗
- ·The MSHTML platform remains active and exploitable even on systems where Internet Explorer 11 has been retired, because it is still used by IE mode in Edge, WebBrowser control, and other legacy applications. ↗

[HIGH] Apple & Microsoft Patch Tuesday, July 2023 Edition
Microsoft Corp. today released software updates to quash 130 security bugs in its Windows operating systems and related software, including at least five flaws that are already seeing active exploitation. Meanwhile, Apple customers have their own zero-day woes again this month: On Monday, Apple issued (and then quickly pulled) an emergency update to fix a zero-day vulnerability that is being exploited on MacOS and iOS devices.
On July 10, Apple pushed a “Rapid Security Response” update to fix a code execution flaw in the Webkit browser component built into iOS, iPadOS, and macOS Ventura. Almost as soon as the patch went out, Apple pulled the software because it was reportedly causing problems loading certain websites. MacRumors says Apple will likely re-release the patches when the glitch

[HIGH] Microsoft discloses more than 130 vulnerabilities as part of July’s Patch Tuesday, four exploited in the wild
Microsoft released its monthly security update Tuesday, disclosing the most vulnerabilities as part of Patch Tuesday in more than a year.
The company released details of more than 130 vulnerabilities, the most in a month since April 2022, 10 of which are considered to be critical. The remaining vulnerabilities are “important.”
Microsoft also included an advisory in today’s Patch Tuesday that provides guidance to mitigate Microsoft-signed drivers that attackers are using maliciously in the wild. Talos recently discovered an attack that focuses on drivers certified by Microsoft’s Windows Hardware Developer Program (MWHDP) being used maliciously in post-exploitation activity. Microsoft had been previously notified of this type of activity in February 2023, and Talos researchers recently rep
