Critical Ivanti Sentry flaw gives unauthenticated attackers root

Ivanti has patched two critical flaws in Sentry, its mobile gateway appliance (formerly MobileIron Sentry) that sits in line between mobile devices and back-end systems like Exchange. The worst, CVE-2026-10520, rated a perfect 10, is an OS command injection in an internal configuration API that mistakenly accepts commands from anyone who can reach it over the internet, with no login, granting remote code execution as root. The second, CVE-2026-10523 (9.9), is an authentication bypass that lets attackers create their own admin accounts. No exploitation has been seen yet, but watchTowr has already published a patch analysis and a detection script, so the window is closing fast.

Check
Identify Ivanti Sentry appliances and their version, restrict who can reach the management and configuration endpoints, and run watchTowr's detection script to confirm whether instances are vulnerable.
Affected
Ivanti Sentry (formerly MobileIron Sentry) versions 10.5.1, 10.6.1, 10.7.0 and earlier, exposed to untrusted networks (CVE-2026-10520 root RCE; CVE-2026-10523 admin-account auth bypass).
Fix
Upgrade Ivanti Sentry to R10.5.2, R10.6.2, or R10.7.1 immediately, then review appliances for rogue administrator accounts and any signs of command execution before patching.

ShinyHunters extorts Oracle PeopleSoft customers in widening data-theft spree

The extortion group ShinyHunters is running a wave of data-theft attacks against organizations using Oracle PeopleSoft, the enterprise software that large institutions rely on for HR, payroll, finance, and student records. Both cloud and on-premises instances are affected, and the gang claims data from more than 100 organizations. Attackers typically log in with stolen employee credentials, move through the PeopleSoft environment, and exfiltrate large datasets before demanding a Bitcoin ransom. A confirmed victim is the University of Nottingham, where a breach of an Oracle student-records system exposed 454,635 accounts. Researchers have shared attacker IP addresses and noted the use of MeshCentral remote-access agents.

Check
Review PeopleSoft access logs for logins from unfamiliar IPs or locations, check for MeshCentral or other unexpected remote-access agents, and confirm whether your org received a ShinyHunters extortion demand.
Affected
Organizations running cloud or on-premises Oracle PeopleSoft, particularly those with reused or phishable employee credentials and limited monitoring of administrative access to HR, finance, and student-records modules.
Fix
Enforce phishing-resistant MFA on all PeopleSoft accounts, rotate exposed credentials, block the shared attacker IPs, remove unauthorized remote-access tools, and tighten access controls and logging on instances.

China-linked JDY botnet scans US military networks for fresh flaws

Lumen's Black Lotus Labs warns that JDY, a covert botnet tied to Chinese state-linked groups including Volt Typhoon, has more than doubled to over 1,500 hacked home and small-office routers, firewalls, and IoT devices. Unlike a DDoS botnet, JDY is a distributed scanning network: it fingerprints exposed services across the internet and flags systems vulnerable to newly disclosed bugs, often within hours of disclosure. It keeps a heavy focus on the US, especially military and associated networks, and survived the 2024 FBI takedown of its parent KV-botnet. Because traffic comes from thousands of ordinary residential IPs, simple IP blocking does not stop it.

Check
Inventory internet-facing routers, firewalls, and IoT devices, especially Ubiquiti, DrayTek, Hikvision, and Linksys gear, for end-of-life models and missing patches that JDY scans for after disclosure.
Affected
Internet-exposed SOHO routers, firewalls, and IoT devices, particularly end-of-life hardware; US military and associated networks are a stated focus of the reconnaissance.
Fix
Patch edge devices promptly after vendor disclosures, replace end-of-life hardware, disable remote management where unneeded, and rely on behavioral rather than IP-based detection for scanning activity.

Six protobuf.js flaws let malicious schemas run code in Node.js apps

Researchers at Cyera have disclosed six vulnerabilities, collectively named Proto6, in protobuf.js, a JavaScript and TypeScript library for Google's Protocol Buffers data format that sees more than 50 million downloads a week. The flaws stem from the library trusting schema and metadata by default, so a single malicious schema or crafted payload can crash a service, inject code, or lead to remote code execution. Cyera demonstrated real attacks including poisoning CI/CD pipelines to leak build secrets and crashing WhatsApp automation bots. Because protobuf.js is embedded across cloud services, AI platforms, and build systems, the reach is broad. Fixed versions are 7.5.6 and 8.0.2.

Check
Inventory applications and pipelines that depend on protobuf.js directly or transitively, and identify any that deserialize Protobuf data or generate code from schemas supplied by untrusted sources.
Affected
Node.js applications, cloud client libraries, CI/CD pipelines, and messaging frameworks using protobuf.js before 7.5.6 or 8.0.2 (CVEs include CVE-2026-44289, CVE-2026-44295) that process untrusted schemas.
Fix
Upgrade protobuf.js to 7.5.6 or 8.0.2 and protobufjs-cli to 1.2.1 or 2.0.2, and treat incoming schemas and descriptors as untrusted input rather than safe data.

Cyberattack halts Australia's second-largest sugar producer mid-harvest

Mackay Sugar, Australia's second-largest sugar producer, has shut down two of its Queensland mills after a cybersecurity incident, halting production and stopping sugarcane harvesting at the peak of the season. The company confirmed the attack on Wednesday and has brought in outside cybersecurity experts and local authorities to investigate and restore systems. It has not yet said who was responsible or whether data was stolen, but the operational shutdown is consistent with a ransomware attack. The incident is the latest example of attackers disrupting food and agriculture operations, a sector whose industrial systems are increasingly targeted for maximum pressure.

Check
Food, agriculture, and manufacturing operators should review how cleanly their IT and operational-technology networks are separated, and confirm a ransomware shutdown of IT could not halt production lines.
Affected
Industrial and agricultural organizations where a compromise of business IT systems can cascade into operational-technology environments and force a full production shutdown, as happened at Mackay Sugar's mills.
Fix
Segment IT from operational-technology networks, keep offline tested backups, rehearse ransomware recovery for production systems, and pre-arrange incident-response and authority contacts before an attack hits.

Microsoft ships record 200-plus June patches, including three zero-days

Microsoft's June 2026 Patch Tuesday is the largest on record, fixing more than 200 vulnerabilities (independent counts put the total above 206), including three publicly disclosed zero-days that are not yet being exploited. The standout is CVE-2026-45586, a Windows CTFMON elevation-of-privilege flaw that grants SYSTEM access, which matches the GreenPlasma bug a researcher dropped in protest of Microsoft's bug-bounty handling; a BitLocker bypass called YellowKey was also fixed. The update includes 33 critical flaws, most of them remote code execution, hitting Remote Desktop, Hyper-V, Office, and cryptographic services. Microsoft flagged 15 issues as more likely to be exploited soon.

Check
Inventory Windows endpoints and servers against the June 2026 update level, and prioritize systems exposed to Remote Desktop, Hyper-V hosts, and anything processing untrusted Office documents.
Affected
Windows, Office, Remote Desktop Client, Hyper-V, Secure Boot, BitLocker, and Exchange. Three publicly disclosed zero-days (CVE-2026-45586, CVE-2026-50507, CVE-2026-49160) and 33 critical flaws, mostly remote code execution.
Fix
Test and deploy the June 2026 security updates promptly, prioritizing the publicly disclosed zero-days and critical RCE flaws. Where patching lags, restrict RDP exposure and segment Hyper-V hosts.

Unpatched Defender zero-day RoguePlanet gives SYSTEM on current Windows

Hours after Patch Tuesday, the researcher known as Nightmare Eclipse published a working exploit, dubbed RoguePlanet, for an unpatched Microsoft Defender flaw that opens a command prompt with full SYSTEM privileges on fully updated Windows 10 and 11. The bug is a race condition, so the exploit is hit or miss, but the researcher reports a 100 percent success rate on some machines. They posted the proof-of-concept on a self-hosted Git server after Microsoft had earlier taken down their GitHub and GitLab repositories. It is the latest in a string of Windows zero-days (BlueHammer, RedSun, YellowKey, GreenPlasma) the researcher has released in protest of Microsoft's disclosure practices.

Check
Confirm Microsoft Defender real-time and tamper protection are enabled and current on Windows 10 and 11 endpoints, and watch for unexpected SYSTEM-level command shells spawned from Defender processes.
Affected
Fully patched Windows 10 and Windows 11 systems, including current and Canary builds, running Microsoft Defender; a public proof-of-concept exists and no fix is available yet.
Fix
No patch exists yet; watch for a Microsoft advisory and apply it when released. Meanwhile, rely on EDR behavioral detection and least-privilege controls to limit privilege-escalation impact.

Google patches actively exploited Chrome V8 zero-day, fifth this year

Google has shipped an emergency Chrome fix for a zero-day in V8, the browser's JavaScript and WebAssembly engine, that attackers are already exploiting in the wild. The flaw (CVE-2026-11645, rated 8.8) is an out-of-bounds memory read and write that lets a malicious web page run code inside Chrome's sandbox, and can help defeat protections like ASLR to set up a fuller compromise. Google confirmed an exploit exists but withheld details until most users update. It is the fifth actively exploited Chrome zero-day of 2026. The fix is in Chrome 149.0.7827.102/103 for desktop; Chromium-based browsers like Edge and Brave need the same update.

Check
Check Chrome and Chromium-based browser versions across managed endpoints (chrome://version or MDM inventory) and confirm they are at or above the June 8 patched build.
Affected
Google Chrome desktop before 149.0.7827.102/103 on Windows, macOS, and Linux (CVE-2026-11645, a V8 out-of-bounds read/write), plus Chromium-based browsers such as Edge and Brave.
Fix
Update Chrome to 149.0.7827.102 or later and relaunch to apply it. Push the update through enterprise policy and patch all Chromium-based browsers in your fleet.

LiteLLM AI gateway flaw exploited for unauthenticated remote code execution

Attackers are actively exploiting a flaw in LiteLLM, a widely used open-source gateway that routes requests to AI models, and CISA has added it to its known-exploited-vulnerabilities list. The bug (CVE-2026-42271) lets any authenticated user run commands on the host through test endpoints that spawn whatever command is supplied in the request. Chained with a separate Host-header bypass in the Starlette web framework (CVE-2026-48710), it becomes unauthenticated remote code execution, giving full control of the server, credential theft, and a foothold in connected AI infrastructure. Horizon3.ai has published a proof-of-concept. It follows a LiteLLM SQL injection flaw exploited within 36 hours last month.

Check
Identify internet-facing LiteLLM proxy deployments and their version, check the Starlette version in use, and review logs of the /mcp-rest/test endpoints for unexpected command execution.
Affected
LiteLLM AI gateway and Python SDK (BerriAI) deployments exposing the vulnerable test endpoints (CVE-2026-42271), especially when paired with Starlette versions vulnerable to the Host-header bypass (CVE-2026-48710).
Fix
Upgrade LiteLLM and Starlette to the fixed releases immediately, restrict the affected endpoints to trusted networks, and rotate any credentials or API keys reachable from the LiteLLM host.

Veeam backup server flaw lets low-privilege domain users run code

Veeam has patched a critical flaw in Backup and Replication, one of the most widely deployed enterprise backup tools, that lets any authenticated low-privilege domain user run code remotely on the backup server. The bug (CVE-2026-44963, rated 9.4) only affects version 12 installations joined to an Active Directory domain; version 13, which uses a different architecture, is not affected, and workgroup setups are safe. No exploitation has been seen yet, but Veeam warns attackers often move quickly once patches reveal the flaw, and backup servers are a prime ransomware target because compromising them cripples recovery. The fix is build 12.3.2.4854.

Check
Identify Veeam Backup and Replication version 12 servers, determine which are joined to an Active Directory domain, and review the domain-user access granted to the backup console.
Affected
Domain-joined Veeam Backup and Replication 12.3.2.4465 and earlier version 12 builds (CVE-2026-44963). Version 13 and workgroup-only deployments are not affected.
Fix
Upgrade to Veeam Backup and Replication 12.3.2.4854 now. Where patching must wait, isolate backup servers from the domain network and tighten which domain users can reach the console.
