Cybersecurity researchers have disclosed details of an unpatched issue that could be exploited to disclose a user's NTLMv2 hash to the attacker. Like in the case of CVE-2026-33829 , which impacted the Windows Snipping Tool's ms-screensketch: URI handler, the newly flagged issue resides in the search: URI handler, per Huntress . CVE-2026-33829 refers to a spoofing vulnerability that could expose sensitive information to an unauthorized actor. It was patched by Microsoft in April 2026. "An attacker could induce the user into clicking a specially crafted link in a Web browser or other URL source, by embedding it in a Web page or email message," Microsoft noted in its advisory at the time. "If the user approves the launching of the link, the crafted URL can induce the computer to connect to an SMB server of the attacker's choosing, which would disclose the user's NTLMv2 hash to the attacker, who could use this to authenticate as the user."

Microsoft has warned of an active cryptojacking campaign that makes use of artificial intelligence (AI) chatbot interactions as a mechanism for surfacing malicious download sites. "This emerging delivery technique extends social engineering beyond conventional search results and increases the visibility of malicious software recommendations," Microsoft Defender Experts and the Microsoft Defender Security Research Team said in a report published Tuesday. The activity, per the tech giant, impersonates legitimate system utilities like CrystalDiskInfo, HWMonitor, Display Driver Uninstaller, FurMark, K-Lite Codec Pack, and PDFgear, likely in an attempt to target users who own high-performance GPUs. The idea is to focus on compromising systems with higher mining value than indiscriminately infecting a large number of machines, it added. The goals of the campaign are not merely financially motivated. The threat actors have also been found to establish persistent remote acce...
