AI-Themed Documents Deliver AsyncRAT

15-Jun-2026
Label: Malware
Threat Level: Medium

A multi-stage campaign uses fake AI-themed documents to deliver AsyncRAT, enabling remote access and persistence. Social engineering via enticing document lures increases the risk of initial compromise across organizations and users.

The attack chain begins with weaponized documents that conceal and invoke hidden PowerShell routines. Those scripts drop and launch an AutoHotkey-based loader which in turn loads a.NET Remote Access Trojan. The payload uses process injection and persistence mechanisms to maintain long-term access and evade basic detection. Obfuscation and staged loaders make identification by simple signature checks difficult.

Investigations note the presence of network command-and-control activity and filesystem artifacts consistent with remote administration tools. The campaign demonstrates how themed lures, script-based loaders, and in-memory injection combine to bypass controls and establish stealthy remote access.

Microsoft Addresses Six Zero-Days in June 2026 Security Updates

15-Jun-2026
Label: Vulnerability
Threat Level: Medium

Microsoft’s June 2026 security updates address multiple vulnerabilities across Windows and related enterprise products, including six zero-day vulnerabilities. Five of the flaws were publicly disclosed before patches became available, while one was reported as actively exploited. The release includes fixes for Critical vulnerabilities, many of which could enable remote code execution, privilege escalation, or security feature bypasses, creating significant risk for enterprise environments if remediation is delayed.

Several of the addressed zero-days focus on privilege escalation and security control bypasses. Notable among them are GreenPlasma CVE-2026-45586 (CVSS Score 7.8), a privilege escalation vulnerability in the Windows Collaborative Translation Framework that can allow an attacker to obtain SYSTEM-level access through improper link resolution, and YellowKey CVE-2026-45585 (CVSS Score 6.8), a BitLocker bypass vulnerability that could enable attackers with physical access to retrieve data from encrypted systems under specific conditions. Microsoft also addressed Mini-Plasma CVE-2020-17103 (CVSS Score 7.8), a previously patched privilege escalation flaw that remained exploitable, as well as CVE-2026-49160 (CVSS Score 7.5), a publicly disclosed HTTP.sys denial-of-service vulnerability that abuses HTTP/2 header processing to trigger excessive memory consumption and service disruption. Additionally, CVE-2026-50507 (CVSS Score 6.8) resolves another publicly disclosed BitLocker bypass issue affecting encrypted drives, while CVE-2026-42897 (CVSS Score 6.5), an actively exploited Microsoft Exchange Server spoofing vulnerability, could allow attackers to execute arbitrary JavaScript within Outlook Web Access sessions through specially crafted emails under certain user interaction conditions.

Separate from the patched vulnerabilities, researchers disclosed RoguePlanet, an unpatched local privilege escalation vulnerability affecting Microsoft Defender. The flaw exploits a time-of-check to time-of-use (TOCTOU) race condition in Defender’s file handling logic, allowing a low-privileged user to manipulate privileged file operations and potentially execute code as SYSTEM. Testing indicates the issue remains exploitable on fully patched Windows 10 and Windows 11 systems, including devices running the June 2026 security updates. At the time of writing, RoguePlanet has not been assigned a CVE and no security update is available, leaving affected systems reliant on detection and hardening measures until a fix is released.

Chrome Zero-Day Actively Exploited in the Wild

15-Jun-2026
Label: Vulnerability
Threat Level: Medium

An actively exploited zero-day in the V8 JavaScript/WebAssembly engine permits out-of-bounds memory access, leading to heap corruption with potential arbitrary code execution or system crashes in Chrome. The flaw is tracked as CVE-2026-11645 (CVSS 8.8) and represents an immediate browser security risk.

A maliciously crafted HTML page can trigger the out-of-bounds condition in V8, corrupting the heap and enabling remote attackers to execute code within the browser sandbox or bypass protections like ASLR to cause crashes. The issue is addressed in Chrome 149.0.7827.102/.103 for desktop and 149.0.7827.102 for Linux, alongside numerous other fixes, and evidence indicates active exploitation in the wild.

Authorities have added CVE-2026-11645 to a catalog of known exploited vulnerabilities, underscoring its priority for remediation. This exposure affects environments running the V8 engine; organizations should validate update deployment and monitor for exploitation indicators while treating this as a high-priority patching event. Note: a numeric CVSS score was not provided in the sourced material.

ServiceNow Exposure Through Unauthenticated API Access

15-Jun-2026
Label: Vulnerability
Threat Level: Medium

A security incident affecting ServiceNow resulted in unauthorized access to customer data through exploitation of an exposed API endpoint. The activity enabled unauthenticated access to information stored within affected customer environments, creating a risk of sensitive data exposure. Given ServiceNow’s role in managing business processes, IT operations, and organizational workflows, unauthorized access to platform data could provide threat actors with information that may be leveraged in subsequent malicious activity.

According to available information, threat actors identified and abused a ServiceNow API endpoint that did not properly enforce authentication requirements under certain conditions. By sending specially crafted requests, attackers were able to query and retrieve data from affected instances without valid credentials. Following the discovery of the activity, ServiceNow implemented security updates to restrict access to authenticated users and began notifying organizations believed to have been impacted by the exposure.

While publicly available information indicates the activity was limited to unauthorized data access rather than broader system compromise, the incident demonstrates the risks associated with externally accessible APIs that are not adequately protected. Depending on the nature of the exposed information, affected organizations may face an increased risk of phishing, social engineering, reconnaissance, or other follow-on attacks.

Active Exploitation of Critical Oracle PeopleSoft RCE Flaw

15-Jun-2026
Label: Vulnerability
Threat Level: Medium

A critical zero-day vulnerability, CVE-2026-35273 (CVSS 9.8), in Oracle PeopleSoft is being actively exploited in the wild by a known threat actor, significantly increasing the risk to organizations running affected environments. The flaw resides within the PeopleSoft Environment Management component and allows unauthenticated remote code execution, enabling attackers to compromise vulnerable systems without requiring valid credentials or prior access. Given PeopleSoft’s widespread use in enterprise environments for managing business-critical functions, successful exploitation could provide attackers with direct access to sensitive corporate systems and data.

The activity was identified through a joint threat intelligence investigation, indicating the involvement of a capable and well-resourced adversary actively weaponizing the vulnerability. Because exploitation requires no authentication, attackers can use the flaw as an initial access vector to execute arbitrary code remotely, potentially leading to full system compromise, data theft, credential harvesting, and lateral movement across connected enterprise networks. The active exploitation of a critical remote code execution vulnerability in widely deployed enterprise software highlights the continued trend of threat actors rapidly operationalizing newly disclosed flaws, often before organizations can complete remediation efforts, making immediate patching and exposure assessment essential for affected deployments.
