SonicWall is warning that two flaws in its SMA1000 remote-access appliances are being actively exploited as zero-days, and has released hotfixes. CVE-2026-15409 is an unauthenticated server-side request forgery bug in the appliance's WorkPlace interface that lets an attacker make the device send requests to internal systems, turning an edge gateway into a pivot point. CVE-2026-15410 is a code-injection flaw in the management console that lets an administrator run operating-system commands, and SonicWall rates the overall advisory a top CVSS score of 10.0. Both were added to CISA's exploited-vulnerabilities catalog, with a federal deadline of July 17. Because exploitation is confirmed, any unpatched appliance should be treated as potentially compromised.
Researchers at ESET found 11 old Microsoft-signed Linux boot components, called shims, that can be used to bypass UEFI Secure Boot on almost any PC, regardless of its operating system. The trick needs no new vulnerability: because these shims were signed years ago with a trusted Microsoft certificate and never revoked, an attacker with admin or boot-level access can copy an old vulnerable shim onto a machine and run untrusted code before the operating system loads. That enables stealthy bootkits that survive reinstalls and start before security tools. Microsoft revoked all 11 in June by blocklisting their hashes, which Windows applies automatically and Linux systems can pull through firmware updates.
Researchers at Miggo disclosed two access-control flaws in RabbitMQ, the widely used message broker, that have been present since early 2024. In the more serious one, an obsolete management endpoint had its authorization check hard-coded to always allow, so an unauthenticated attacker can leak the broker's confidential OAuth client secret in a single request, a direct path to full broker takeover where that secret is used. The second lets any logged-in user, even one with no assigned permissions, read other tenants' queue and exchange metadata, useful reconnaissance in shared environments. Both are fixed in updated releases, and the risk is sharpest where the management port is reachable from untrusted networks.
Researchers at JFrog found 148 npm packages that abused the registry not to attack developers but as free hosting for a booby-trapped web proxy aimed at students trying to bypass school filters. Anyone who opened one of the proxy sites had their browser quietly conscripted into a distributed denial-of-service botnet, flooding target servers with HTTP and WebSocket traffic, alongside injected ads and tracking. Crucially, the packages contained no install-time scripts and were never meant to be added to a project, so dependency scanners and install sandboxes, which watch what runs on install, would not catch them. The operators can re-arm the dormant attack code with a single commit.
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.
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.
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.
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.
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.
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.
