LabubaRAT poses as NVIDIA software to take remote control of Windows machines

Researchers at Blackpoint Cyber detailed LabubaRAT, a previously undocumented Rust-based remote access trojan that disguises itself as NVIDIA software to blend into target systems. It arrives as an executable impersonating NVIDIA's container runtime, then profiles the host, identifying installed browsers and security products such as Microsoft Defender, CrowdStrike, and SentinelOne. From there it can run commands and scripts, capture screenshots, move files, and proxy traffic, and it communicates over multiple channels, including HTTPS, WebView2, and DNS tunneling, so access survives if one path is blocked. Its command server details are supplied at runtime, letting attackers reuse the same binary across campaigns, and there are signs it is sold as a service.

Check
Watch for executables impersonating NVIDIA components, such as an unexpected nvidia-sysruntime.exe, and hunt for host-profiling behavior and command-and-control over DNS tunneling or WebView2 that endpoint tools may not flag by default.
Affected
Windows environments where an attacker can plant the malware; LabubaRAT gives hands-on remote control, identifies and works around security tools, and maintains access over several channels, making it hard to fully evict.
Fix
Verify NVIDIA and other software against official sources, deploy endpoint detection tuned for host-profiling and multi-channel command-and-control including DNS tunneling, restrict outbound traffic, and investigate unexpected proxy or SOCKS activity from endpoints.

Fake LastPass and Bitwarden security alerts lure users to phishing sites

LastPass is warning that attackers are impersonating it and Bitwarden with fake security alerts to lure password-manager users to phishing sites. The emails, sent from look-alike domains rather than the real services, mimic corporate notices about updated security policies and push recipients to a page impersonating DocuSign. LastPass stresses its systems were not breached and the messages did not come from its infrastructure. Password managers are attractive phishing targets because compromising one can unlock every stored credential, and users often trust vendor-branded alerts. Related campaigns have pushed fake more-secure desktop apps that actually install remote-access tools, and similar lures have impersonated other password managers.

Check
Remind users that password-manager vendors do not ask for the master password, and to verify any breach or policy alert by logging in through the official site or app, not emailed links.
Affected
LastPass and Bitwarden users, and by extension every credential in their vaults; convincing vendor-branded alerts from look-alike domains can trick them into entering their master password or installing remote-access malware.
Fix
Verify security notices through official portals, enable phishing-resistant multi-factor authentication on password managers, and if credentials were entered on a phishing site, change the master password from a trusted device.

CISA adds actively exploited Cisco IOS flaw to its must-patch catalog

CISA has added a Cisco IOS vulnerability to its Known Exploited Vulnerabilities catalog after confirming it is being used in real attacks, requiring federal agencies to patch it under a binding deadline. Cisco IOS and IOS XE run the routers and switches behind many enterprise and service-provider networks, so a flaw here can give attackers a foothold deep in the network path. The listing lands amid heightened warnings, including a joint US-and-allies advisory this week urging better router hygiene against Russian state-sponsored targeting of network devices. Network gear is attractive because it often sits unmonitored, stays online for years, and rarely runs endpoint security; timely patching is the main defense.

Check
Identify Cisco IOS and IOS XE devices, check them against Cisco's advisory for the newly listed flaw, and prioritize patching internet-facing and edge devices while reviewing configurations and logs for tampering.
Affected
Organizations running affected Cisco IOS or IOS XE network devices, especially internet-facing routers and switches; active exploitation means unpatched devices are at real risk of compromise deep in the network path.
Fix
Apply Cisco's fixed software promptly, restrict and monitor management interfaces, follow current router-hygiene guidance against state-sponsored targeting, and inspect device configurations and logs for signs of unauthorized changes.

Lidl notifies online shop customers of breach at a service provider

Discount supermarket chain Lidl has notified online shop customers in Germany, Belgium, and the Netherlands of a data breach that stemmed from a hack at one of its service providers rather than Lidl's own systems. According to the company, the exposed information involves customer contact and order-related details, while payment card data was not affected. The incident is another example of third-party or supply-chain risk, where attackers compromise a vendor to reach a larger brand's customer data. Even without financial data, the exposed details can fuel convincing phishing and scams that impersonate Lidl, especially messages referencing real orders to make fraudulent requests look legitimate to shoppers who recently used the online shop.

Check
Lidl online shop customers in the affected countries should watch for the notification, be wary of messages referencing Lidl or their orders, and avoid clicking links or sharing details in unsolicited messages.
Affected
Lidl online shop customers in Germany, Belgium, and the Netherlands whose contact and order details were exposed through a hacked service provider; payment card data was not affected.
Fix
Treat Lidl-themed messages with caution and verify through official channels. Organizations should assess vendors' security, limit the customer data third parties hold, and require breach-notification and security commitments in supplier contracts.

MemGhost plants lasting false memories in AI assistants through a single email

Researchers demonstrated MemGhost, an attack that uses one email to plant a false, persistent memory in an AI personal assistant with inbox access. Because these assistants keep notes about the user and reload them every session, a crafted message can trick the agent into saving a fabricated fact while keeping its reply innocuous, so the tampering goes unnoticed and steers later answers. The team trained an attacker model to write such emails automatically, reporting high success against open-source and commercial agents and showing it transfers across memory backends and survives several defenses. Unlike earlier one-shot injection that leaked data only in the moment, MemGhost's memory persists long after the email is gone.

Check
Review whether AI assistants in use have persistent memory and can read untrusted content, and check what controls govern what gets written to memory and whether changes are visible to the user.
Affected
Users of AI personal assistants with persistent memory and inbox access; a single crafted email can silently write a false memory that biases the assistant's answers across future sessions.
Fix
Prefer assistants that log and let users review memory changes, restrict what untrusted content can write to long-term memory, isolate memory from email-triggered actions, and periodically audit stored agent memories.

CrashStealer Mac malware uses an Apple-notarized app to slip past Gatekeeper

Jamf detailed CrashStealer, a macOS infostealer delivered through a signed, Apple-notarized app called Werkbit that passes Gatekeeper, since it carried a valid developer ID before Apple revoked it. Distributed as a disk image and gated behind a meeting PIN so it is served only to targeted visitors, the malware validates the victim's login password locally, then harvests broadly from browsers, cryptocurrency wallets, password managers, and the keychain, encrypting the loot before sending it out. It persists by copying and re-signing itself. There is no zero-click stage: a victim still runs the app and enters their password, but the notarized delivery and careful targeting make it more convincing than typical Mac stealers.

Check
Remind Mac users that notarization does not guarantee an app is safe, to be cautious of apps delivered by disk image behind meeting codes, and to refuse password prompts from unexpected installers.
Affected
Mac users who download and run the notarized Werkbit app and enter their password; CrashStealer then steals browser data, crypto wallets, password-manager contents, and keychain secrets, and reinstalls itself to persist.
Fix
Install apps only from trusted sources, treat unexpected password and disk-image prompts with suspicion, keep macOS and endpoint tools updated to catch known indicators, and monitor for apps copying and re-signing themselves.

Popular ModHeader dev extension pulled after hidden history collector found

Google and Microsoft removed ModHeader, a header-editing browser extension popular with developers, with about 1.6 million installs, after researchers at Stripe OLT found a hidden browsing-history collector inside the official, signed store version. The collector was dormant, gated off by an empty allow-list, and no evidence has emerged that it ever sent data, but its presence in a trusted, signed extension is the concern. Its design frustrated automated review: the data was encrypted, the upload was switched off so sandboxes saw nothing leave, and malicious code was blended into a legitimate codebase, so scanners rated it low risk. It is a reminder that a store signature proves origin, not safe behavior.

Check
Check whether ModHeader is installed on developer or tester machines, remove or update it per the vendors' guidance, and review which browser extensions have broad permissions across your organization.
Affected
Developers and testers who installed ModHeader, and their organizations; a trusted, signed extension shipped a dormant collector capable of recording visited domains, showing signed extensions can still hide unwanted behavior.
Fix
Govern browser extensions with allow-lists and permission reviews, do not treat a store signature as proof of safe behavior, prefer minimal necessary extensions, and monitor for extensions contacting unfamiliar external endpoints.

Exposed server unmasks three Evilginx phishing crews stealing Microsoft 365 sessions

A phishing operator left a Python web server exposed with directory listing on, letting researchers at Lexfo lift the entire toolkit and pivot to two more operators running three Microsoft 365 phishing campaigns. Each used a custom fork of the open-source Evilginx proxy to steal live session cookies and tokens, defeating multi-factor authentication by relaying the real login. The largest campaign ran over a year, logging 218 captured accounts, mostly corporate mailboxes, and a token file left in a public repository held 97 live Microsoft tokens. The report stresses two different MFA-bypass methods appeared, one proxying the real login and one abusing the device-code flow, which require different defenses to stop.

Check
Assess your Microsoft 365 defenses against both adversary-in-the-middle proxying and device-code abuse, hunt for suspicious token use and session reuse from unusual locations, and review Conditional Access coverage of the device-code flow.
Affected
Microsoft 365 organizations, especially corporate mailboxes; Evilginx-style proxies steal live session tokens to bypass MFA, and passkeys stop the proxy method but not the separate device-code abuse technique.
Fix
Enforce phishing-resistant authentication like passkeys against proxy phishing, use Conditional Access to block or limit the device-code flow, revoke suspicious sessions and tokens, and monitor sign-in logs for token reuse across locations.

Japan's largest taxi operator shuts down systems after a cyberattack

Nihon Kotsu, Japan's largest taxi operator, shut down internal systems after a cyberattack, disrupting parts of its operations while it investigates and recovers. Precautionary shutdowns like this are a common response to intrusions such as ransomware, aimed at containing an attacker and limiting damage while forensic work proceeds, though they also interrupt normal business. The incident fits a broader pattern of attacks against transportation and logistics providers, whose real-time operations and large customer bases make downtime costly and pressure on victims high. Full details, including whether customer data was accessed, were not yet available, but the disruption underscores how operational technology and business systems in transport are increasingly targeted.

Check
Transportation and logistics operators should review their ability to detect and contain intrusions quickly, test whether critical operations can continue during a systems shutdown, and confirm backups and incident-response plans are current.
Affected
Transportation and logistics providers whose real-time operations make downtime costly; attackers target them for disruption and leverage, and a breach can force a business-halting precautionary shutdown before data impact is known.
Fix
Segment operational and business systems, maintain tested offline backups and an incident-response plan, enforce phishing-resistant MFA on remote access, and rehearse continuing critical services during a partial or full systems shutdown.

CISA flags two exploited Joomla extension flaws that let attackers upload web shells

CISA has added two actively exploited vulnerabilities to its Known Exploited Vulnerabilities catalog, both in popular Joomla extensions and both allowing attackers to upload dangerous files. The iCagenda event calendar flaw (CVE-2026-48939, rated 10.0) lets an attacker upload arbitrary files through its attachment feature, ending in PHP code execution, while the Balbooa Forms flaw (CVE-2026-56291) allows unauthenticated upload of executable files leading to full remote code execution. Federal agencies were ordered to fix them by July 13. The additions line up with a broader campaign, recently flagged by Australia's cyber agency, in which attackers scan the internet and exploit known content-management-system and plugin flaws to plant web shells on vulnerable sites.

Check
Identify Joomla sites using the iCagenda or Balbooa Forms extensions, update them to fixed versions, and inspect web directories for unexpected PHP files or web shells indicating a successful upload.
Affected
Websites running the iCagenda or Balbooa Forms Joomla extensions (CVE-2026-48939, CVE-2026-56291); attackers are actively uploading malicious files to gain remote code execution and plant web shells on affected servers.
Fix
Update the affected extensions to patched versions, remove unused plugins, make web directories read-only where possible, monitor for unauthorized file creation, and block unexpected child processes spawning from web servers.
