Unpatched Windows Search URI Vulnerability Lets Attackers Steal NTLMv2 Hashes

Cybersecurity researchers have identified an unpatched vulnerability that could expose NTLMv2 hashes to attackers, linked to the "search:" URI handler. This issue is similar to CVE-2026-33829, which involved a spoofing vulnerability in the Windows Snipping Tool's ms-screensketch: URI handler. The flaw allows attackers to trick users into connecting to their SMB servers, disclosing NTLMv2 hashes for authentication exploitation. The new vulnerability operates using "search:" and "crumb=location:" parameters, resulting in a similar Net-NTLMv2 leak. Microsoft has chosen not to address this issue, stating only vulnerabilities classified as Important or Critical would be fixed. Recommendations to mitigate risks include blocking outbound SMB traffic, enforcing SMB signing, and disabling NTLM authentication where possible.

Windows platform security for AI agents

AI agents have evolved from simple question-answering systems to autonomous entities that can perform actions across various platforms. This shift raises concerns about control and trust, necessitating a change in security paradigms. Developers are now required to integrate security into the architecture of their platforms to maintain trust in agent deployment. Microsoft has expanded Agent 365 to manage local agents on Windows, introducing policy-based controls to govern agent actions. The Microsoft Execution Containers (MXC) SDK provides a policy-driven execution layer for agents, allowing developers to define constraints and ensuring consistent enforcement at runtime. Windows supports various containment options, including process and session isolation, to mitigate risks associated with agent behavior. Micro-VMs and Linux containers are also being integrated into the containment model. Windows 365 for Agents enables agents to operate in a managed cloud environment, limiting potential compromises. Collaborations with industry leaders aim to align containment strategies with developer needs. The security model is built on a foundation designed to minimize risk, incorporating features like passwordless sign-in and real-time protection through Windows Defender. The focus remains on enabling developers to create secure, governable agents for real-world deployment.

NordVPN’s New App Acts as an All-in-One Digital Privacy and Security Hub

A virtual private network (VPN) does not protect against fraudulent banking links or harmful files. NordVPN has enhanced its VPN application by integrating antivirus features, evolving into a comprehensive digital privacy and security service. The revamped app is based on three pillars: Connect, Protect, and Monitor, offering tools such as VPN services, scam and phishing protection, and Dark Web Monitor. NordVPN's approach aims to intercept threats early, focusing on deception tactics used in modern scams. The company's next-generation antivirus system uses a dual-layer detection strategy, evaluating URLs in real-time and scanning files for malware. In April, NordVPN blocked 4.8 million threat events, including malware and phishing attempts. The company emphasizes minimal data collection for threat decisions and offers three subscription tiers: Basic, Complete, and Prime, each with a 30-day money-back guarantee. Users are reminded that no app can fully protect against cybersecurity threats, and best practices like strong passwords and multifactor authentication are essential.

Windows shell spoofing vulnerability puts sensitive data at risk

Erik Avakian, a technical counselor at Info-Tech Research Group, discussed the patching deadlines set by the Cybersecurity and Infrastructure Security Agency (CISA) under Binding Operational Directive (BOD) 22-01, which requires U.S. federal agencies to address vulnerabilities within 14 to 21 days. CISA can expedite patching to as little as three days for high-risk exploits. The vulnerability CVE-2026-32202, rated 4.3 on the Common Vulnerability Scoring System (CVSS), was actively exploited but did not qualify for an urgent patch cycle, resulting in a 14-day deadline. Avakian noted the debate over whether this timeframe is sufficient, suggesting that Microsoft’s rating and other factors influenced the decision not to escalate to an emergency directive requiring a 48 to 72-hour response.

Fileless Malware and Email Authentication Gaps

Fileless malware operates stealthily within networks, utilizing legitimate system tools like PowerShell and Windows Management Instrumentation (WMI) to execute malicious code in memory without leaving traces on disk. Traditional antivirus solutions struggle to detect these threats due to their reliance on file signatures. The primary vector for fileless malware is email, where attackers use spoofed messages to trick users into activating malicious scripts. Misconfigurations in Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records create vulnerabilities that attackers exploit to deliver spoofed emails. Traditional endpoint protection mechanisms are inadequate against fileless attacks, necessitating a shift towards behavioral analysis for detection. Organizations must assess their preparedness by ensuring proper email authentication configurations and enhancing endpoint security capabilities. Integration among security teams and updated employee security awareness programs are also essential. Sendmarc helps organizations mitigate vulnerabilities by providing visibility into SPF, DKIM, and DMARC configurations and enforcing DMARC to block unauthenticated messages.

Your Android phone could soon get a better way to sniff out spoofed calls

Google is enhancing the security of incoming calls on Android devices by integrating a "Verified Caller" feature into Google Play Services. This feature aims to combat scam calls that use Do-Not-Originate (DNO) numbers by cross-referencing incoming calls against a database of DNO numbers to flag potential scams. The system will work with existing applications, such as banking apps, to monitor specific DNO numbers. The feature is still in development and its effectiveness will depend on business participation and strict verification processes by Google.

Undeliverable? Why the Kremlin might be set to silence online messaging apps in Russia.

Residents of Moscow are experiencing GPS spoofing in downtown areas, leading many to use paper maps instead of digital navigators due to signal manipulation by security forces to counter Ukrainian drones. The Russian government is "throttling" popular messaging apps like WhatsApp and Telegram in favor of a domestically developed super-app named Max. This strategy aims to reshape online interactions in Russia and is part of broader efforts to control the digital landscape. Analysts suggest that this could lead to a near-total internet shutdown during emergencies, with a published "whitelist" of about 900 essential websites. The internet disruptions have particularly affected younger generations who rely heavily on social networks and online services. Russia's media regulator, Roskomnadzor, has blocked foreign platforms for non-compliance with data localization laws and is targeting messaging apps, making them largely unusable without VPNs. Telegram may face a complete shutdown on April 1. Despite the crackdown, state agencies continue to use Telegram for communication, while security services view these apps as potential threats.

Fake Red Alert app used in Android spyware smishing

Acronis' Threat Research Unit has discovered a targeted campaign against Android users involving a counterfeit version of Israel's Red Alert rocket warning app that distributes spyware. The malicious software is spread through SMS messages that appear to be official communications from the Home Front Command, prompting users to download an "update." The fraudulent app mimics the legitimate safety tool, maintaining its rocket alert functionality to avoid detection. Once installed, the spyware collects sensitive data such as SMS messages, contacts, location information, device accounts, and a list of installed applications. This tactic, termed "smishing," combines SMS and phishing techniques. The malware uses sophisticated methods like certificate spoofing and runtime manipulation to bypass Android's signature checks, and it consists of a loader and a secondary component that executes the real alert application while the spyware operates in the background. The spyware monitors user permissions and can harvest SMS messages, contacts, and location data, adjusting its behavior based on the user's geographical position. It sends collected data to a remote command-and-control server, with the exfiltration endpoint identified as ra-backup[.]com. Acronis suggests this campaign may be linked to the group Arid Viper (APT-C-23), known for targeting Israeli interests with trojanized Android applications. Researchers recommend users only download apps from official sources, avoid sideloading packages from SMS links, and review app permissions carefully. They advise checking for the package name com.red.alertx on devices and performing a factory reset if found, along with changing credentials for any accessed accounts.
