CrashStealer Mac malware steals passwords and wallets

A sophisticated new malware targeting Mac users, named CrashStealer, has been discovered by security researchers at Jamf Threat Labs. It masquerades as Apple's legitimate crash-reporting software and was first identified in May 2026, with active attacks detected by early July. CrashStealer is designed to extract sensitive information, including browser credentials, password manager data, and cryptocurrency wallet information, and can copy the Mac login Keychain. It uses native C++ programming, encrypts collected files, and employs anti-debugging features. The malware is distributed through a disk image labeled "Werkbit Setup," which features a polished installer that bypasses Mac security warnings by using a valid Apple Developer ID and notarization ticket. Once opened, it connects to GitHub for commands and downloads a script that installs a second disk image named CrashReporter.dmg, which mimics an Apple system component. CrashStealer presents a fake password prompt resembling a legitimate macOS request, verifying entered passwords locally. It targets data linked to various browsers and password managers, scanning for approximately 80 cryptocurrency wallet extensions and 14 password managers. Stolen data is stored in hidden folders, encrypted using AES-256-GCM, and packaged into hidden ZIP archives before being uploaded. Warning signs of infection include a website requiring a meeting PIN for download, unexpected password prompts, and unfamiliar apps requesting Full Disk Access. Users are advised to download apps from verified sources, avoid overriding security warnings, pause before entering passwords, review app permissions, install security updates, use antivirus software, and act quickly if they installed Werkbit Setup.

LG Monitors Spotted Installing Adware-Like App on Windows PCs

LG monitors connected to Windows PCs can trigger the automatic installation of the LG Monitor App Installer, which promotes paid subscriptions to McAfee antivirus software without user consent. This app appears shortly after Windows Update installs relevant LG packages, displaying McAfee promotions frequently. The app is designed to launch at startup and operates outside the Windows App Sandbox, raising cybersecurity concerns. Reports indicate that this issue affects both newer and older LG monitor models. Microsoft allows manufacturers to link Store applications with device metadata, enabling such installations without clear user choice. Users can remove the app through Windows Settings, but doing so may block other useful applications. LG and Microsoft have not publicly addressed these concerns.

Researcher Drops New Windows Zero-Day PoC Hours After Microsoft Patch Tuesday

Security researcher Chaotic Eclipse has released a proof-of-concept exploit called LegacyHive, which targets a vulnerability in the Windows User Profile Service. The exploit requires standard user credentials and a third username, potentially an administrator account. It can mount the target user hive in the current user classes root and is designed to reduce the risk of public exploitation. The exploit works across all supported desktop and server versions of Windows, including those updated with the July 2026 Patch Tuesday release. Microsoft is investigating the findings related to LegacyHive. Microsoft has patched 622 vulnerabilities, including two privilege escalation flaws in SharePoint Server (CVE-2026-56164, CVSS score: 5.3) and Active Directory Federation Services (CVE-2026-56155, CVSS score: 7.8), which are actively exploited threats. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has included these vulnerabilities in its Known Exploited Vulnerabilities catalog, requiring Federal Civilian Executive Branch agencies to implement fixes by specified deadlines. CISA has also noted active exploitation of several SharePoint Server vulnerabilities, including CVE-2026-32201, CVE-2026-45659, and CVE-2026-56164, which allow unauthorized access to vulnerable instances. CVE-2026-56164 enables attackers to send crafted network requests to access functions that should require authorization, leading to privilege escalation without prior authentication. Additionally, CVE-2026-55040 (CVSS score: 9.1) allows remote unauthenticated attackers to bypass authentication on a vulnerable SharePoint server, enabling unauthorized operations.

ESA Lobbyist Calls Private Minecraft Servers Illegal During Hearing

Jennifer Gibbons, Vice President of State Government Affairs at the Entertainment Software Association (ESA), stated during a California State Senate hearing that community servers for Minecraft and Call of Duty are "illegal" and equate to "piracy." She mentioned that the ESA has pending lawsuits against private servers and that the United States Trade Representative (USTR) has identified some private servers as notorious markets for piracy. Gibbons' comments were challenged by Assemblyman Chris Ward, who noted the existence of community servers for both games. An ESA representative later clarified that Gibbons was responding to a complex question and that private servers hosting copyrighted content without authorization infringe on the intellectual property rights of game publishers. The ESA reported a total revenue of ,614,556 in the fiscal year ending March 2025, with ,804,681 from member dues.

ESA Claims Private Minecraft Servers Are ‘Illegal’ and ‘Piracy’ in Stop Killing Games Hearing

The California State Senate hearing on the Protect Our Games Act raised questions about the legality of private Minecraft servers. Assemblyman Chris Ward noted that games like Minecraft and Call of Duty have successfully used community servers, while Jennifer Gibbons from the ESA argued that these servers are illegal and unapproved by Microsoft, labeling them as piracy. Gibbons stated that the ESA has two lawsuits against private servers for infringing on intellectual property rights. In contrast, Minecraft's official stance encourages the creation of third-party servers, which are vetted for compliance with community standards. The ESA maintains that private servers infringe on publishers' rights. The USTR's Notorious Market Report referenced by Gibbons does not specifically target community servers for connecting friends but focuses on those bypassing subscription services. The Protect Our Games Act did not advance but will be reconsidered. An ESA representative later clarified that private servers hosting copyrighted content without authorization infringe on publishers' rights and highlighted concerns about safety standards on these platforms.

Active Exploitation of Critical CVE-2026-20253 in Splunk Enterprise: Unauthenticated RCE via PostgreSQL Sidecar Service

A critical security vulnerability, SVD-2026-0603 (CVE-2026-20253), has been identified in Splunk Enterprise versions 10.0.0 through 10.0.6 and 10.2.0 through 10.2.3. This flaw allows unauthenticated, remote attackers to create or truncate arbitrary files on the host system by exploiting the PostgreSQL Sidecar Service endpoints. The vulnerability is actively exploited, with public proof-of-concept code available, and has been added to the CISA Known Exploited Vulnerabilities (KEV) list. Successful exploitation can lead to full remote code execution (RCE) as the Splunk user. The vulnerability arises from inadequate authentication controls on the PostgreSQL Sidecar Service endpoints, specifically /v1/postgres/recovery/backup and /v1/postgres/recovery/restore, which are accessible without authentication. It is classified under CWE-306: Missing Authentication for Critical Function and has a CVSS v3.1 base score of 9.8 (Critical). Attackers can exploit the vulnerability by sending crafted HTTP POST requests to the exposed endpoints, allowing them to create or truncate files and potentially execute malicious scripts. Indicators of compromise include unexpected files in directories such as /tmp/ or /opt/splunk/var/run/supervisor/pkg-run/, modified Splunk Python scripts, and unusual outbound connections from Splunk to unknown PostgreSQL servers. The vulnerability aligns with several MITRE ATT&CK techniques, including T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter). Active exploitation of CVE-2026-20253 has been confirmed, and it is likely that both opportunistic cybercriminals and sophisticated threat actors will use this exploit. The affected versions of Splunk Enterprise are 10.2.0 through 10.2.3 and 10.0.0 through 10.0.6, with the issue resolved in versions 10.2.4 and 10.0.7. Organizations are advised to upgrade to fixed versions or disable the PostgreSQL Sidecar Service as a mitigation strategy.

Free Software Foundation Europe pushes EU to force Google to allow AI uninstalls on Android

The Free Software Foundation Europe (FSFE) has raised concerns with the European Commission regarding AI features in Android devices, specifically that Google installs AI models without user consent and that these models can automatically reinstall after being deleted, violating the Digital Markets Act (DMA). The FSFE advocates for users to fully uninstall pre-loaded AI components without silent reinstallation and for access to interoperability features to be independent of registration with Google. Google plans to implement an Android Developer Certification by September 2026, requiring developers to register with the company to publish apps on certified devices, which has raised concerns for Free Software developers and those in regions where revealing identity could lead to surveillance. The FSFE warns that unchanged draft measures could allow Google to enforce identity verification for developers, contradicting the DMA's intent.

How We Test Antivirus and Security Software

Most software applications clearly indicate their functionality, but the effectiveness of antivirus utilities is often less tangible. PCMag rigorously evaluates antivirus products through comprehensive tests that validate their claims, including real-world malware samples and various protective measures. Each antivirus tool is assessed based on its on-demand scanner and real-time monitor capabilities. PCMag compiles fresh malware samples annually, analyzing them to ensure they are suitable for testing. The testing process includes evaluating malware-blocking capabilities and web-level protection against known malware-hosting sites. Phishing site detection is also tested using recent URLs, and antispam testing has been simplified due to the effectiveness of email providers. Performance impact tests have been discontinued as modern security suites show improved efficiency. Firewall protection is evaluated through program control, exploit defenses, and overall resilience against malware. Parental control features are tested for effectiveness in content filtering and monitoring. Ransomware protection is assessed by releasing real-world samples in a controlled environment. PCMag monitors independent antivirus lab tests from various organizations, including AV-Test, AV-Comparatives, SE Labs, MRG-Effitas, and AVLab, to inform their reviews. An aggregate testing score is calculated to summarize lab results. Testing methodologies do not include VPN evaluations, which are covered separately.
