Healthcare and services provider Nutex is investigating a data breach incident where an unauthorized third party exfiltrated information from company servers. The organization has disclosed the cyberattack in a filing with the U.S. Securities and Exchange Commission (SEC), noting that the stolen data includes details that may be private or confidential. “Based on preliminary findings from the Company’s ongoing investigation, the Company believes that certain information maintained on the Company’s servers was accessed and exfiltrated by an unauthorized third party, including some information that may be private and/or confidential,” Nutex says. Nutex Health is a for-profit healthcare company that operates 28 facilities across 12 states, including the Bayou City ER & Hospital in Texas and Green Bay ER & Hospital in Wisconsin.
Attackers are increasingly targeting the processes used to establish or recover identity rather than attacking the login itself. Specops explains how stronger identity verification can help organizations prevent fake workers and social engineering attacks from gaining legitimate access.
Microsoft updated its Windows PowerToys toolset with a new utility dubbed "Window Hopper" that lets users switch between an app's windows more quickly. The Window Hopper added in this release works like the standard ALT + TAB Windows feature, but it only works for the currently focused app, helping users switch back and forth between its windows. "Once the utility is enabled, press the configurable Alt + backtick shortcut to cycle through that app's windows without stepping through everything else on your desktop," Microsoft explains. "It is especially useful when you're juggling multiple browser windows, terminals, File Explorer windows, or editor instances." Those who want to customize the default activation keyboard shortcut can also do so in PowerToys settings to switch to the next and previous app window.

WeedHack Minecraft Malware Survives C2 Takedown: Fake Client Sites Still Active, SEO Poisoning Puts Malicious Downloads at the Top of Google McAfee Labs published a follow-up report on the WeedHack Malware-as-a-Service campaign this week, documenting ten active malicious sites and multiple file-hosting accounts that are still spreading the infostealer despite a disruption to its command-and-control infrastructure. Over the past month alone, McAfee WebAdvisor blocked more than 6,300 user attempts to reach these sites. WeedHack was first spotted in early June 2026 when McAfee researcher Aayush Tyagi documented a Malware-as-a-Service operation that had been running since January and had logged 116,464 infected systems, adding between 2,000 and 3,000 new victims every day. The operation offered a free tier that anyone with a Discord account could access, a premium tier with webcam surveillance capability for $5 a month, and a dashboard letting operators view stolen credentials, configure custom payloads, and monitor victims in real time. It spread through fake Minecraft client websites, YouTube videos linking to malicious downloads, and SEO poisoning that pushed those fake sites to the top of search results for popular Minecraft tool names. The malware stole session cookies, passwords, browser data, and cryptocurrency wallet contents, and used EtherHiding, a technique that fetches the attacker’s active server address from the Ethereum blockchain, to maintain contact with its infrastructure even when individual servers were shut down. “During our investigation of this campaign, we observed that most of these websites appear legitimate, as they are well-crafted and often mimic legitimate websites. We observed a series of dedicated brand-impersonation attacks targeting several popular Minecraft clients.” reads the report published by McAfee. “We published the original article in the first week of July, and, as a result, we’ve seen a disruption in WeedHack’s campaign: its C2 server is no longer active. Consequently, we have observed a shift in tactics by these attackers. “ The dashboard is gone. The distribution sites are not. Each fake website copies the real tool’s features, FAQs, installation steps, developer information and even links to legitimate GitHub repositories. The sites look detailed and convincing, so most users have little reason to suspect anything. The attackers also use search rankings to reach victims. Researchers found that the first two Google results for “Xenon Client,” a popular Minecraft client, led to fake sites distributing WeedHack. The sites offered installation guides, free and paid downloads, and links to the real Xenon Client GitHub repository. A player searching for the tool, clicking the first result and downloading the file could easily end up installing malware. The campaigns exploit a structural weakness in the Minecraft modding community: many popular tools don’t have official websites, only GitHub pages and Discord servers. Nova-client.com is a fake website for a client that has no real website; the attackers built one and ranked it above the genuine GitHub repository. 22qq-client.com does the same for a Crystal PVP mod. For nova-client.com, the researchers specifically noted that the credits section lists generic team names instead of anyone who actually worked on the project, which is one of the cleaner ways to spot an impersonation if you know who the real developers are. One site in the campaign was built using lovable.app, an AI-powered web application builder that accepts natural language instructions and produces working sites. The platform is legitimate; the use here is not. The ready availability of tools like this means the cost and technical skill required to launch a new convincing fake gaming site is now close to zero. McAfee found that most malicious links came through Discord (49.6%), followed by MediaFire (23.4%), GitHub (8.2%) and Dropbox (4.6%). One Discord channel promoting fake DonutSMP clients had more than 1,900 members, while another site offered eight different mods that all delivered the same malware. The campaign also spread through trusted Minecraft communities such as Planet Minecraft and EndMods, making the scams harder to spot because users already trusted these platforms. McAfee recommends downloading mods and clients only from official developer repositories or trusted platforms such as Modrinth and CurseForge.

Bad actors are attempting to exploit two severe unauthenticated authentication bypasses in the Xecurify miniOrange SAML 2.0 Single Sign On plugin that make it possible for an attacker to sign in as any WordPress user, including administrators. The vulnerabilities, as disclosed by Patchstack, are listed below - CVE-2026-61979 (CVSS score: 8.1) - An unauthenticated privilege escalation
Hackers are attempting to exploit two critical authentication bypass vulnerabilities in the miniOrange SAML 2.0 Single Sign On plugin for WordPress that can be used to forge SAML responses and log in as administrators. The miniOrange SAML SSO plugin turns a WordPress site into a SAML service provider, letting users log in through corporate identity platforms such as Microsoft Entra ID, Okta, Google Workspace, or OneLogin instead of separate WordPress credentials. Created by Xecurify, miniOrange is a family of seven plugins, with a free version that has 10,000 downloads and 30,000 customers for the other six. The two vulnerabilities observed in exploitation attempts are tracked as CVE-2026-61979 and CVE-2026-15981 and can be chained together to bypass authentication. Because the miniOrange SAML SSO plugin accepts the signature algorithm from incoming SAML responses instead of enforcing the configured one, an attacker can leverage CVE-2026-61979 to select HMAC-SHA1. This causes the plugin to treat the RSA public key from the identity provider (IdP) as the shared secret.
Cybersecurity company ReliaQuest has confirmed that one of its employees was targeted in a social engineering attack after hackers impersonated a member of the security team. In a statement over the weekend, ReliaQuest said that an attacker called multiple employees and tried to trick them into accessing "a fake ReliaQuest single sign-on (SSO) page behind a content delivery network." Last week, ReliaQuest's Threat Research team shared in a now-deleted post, that the ShinyHunters extortion gang was registering .claims domains to impersonate company's help desks and IT teams. "ReliaQuest is tracking a widespread ShinyHunters campaign using domains that follow the company[.]claims pattern. These domains incorporate the targeted organization’s name or abbreviation under the .claims TLD," read the company's post on X.
