Januscape is a 16-year-old Linux kernel vulnerability, tracked as CVE-2026-53359, that lets attackers escape a KVM virtual machine and execute code as root on the host. The flaw affects multi-tenant cloud environments and can be chained with Dirty Frag to achieve full compromise on unpatched systems. #Januscape #CVE-2026-53359 #KVM #DirtyFrag

Organizations are still facing persistent phishing, business email compromise, and account takeover attacks even after investing in secure email gateways, MFA, and identity protection. A BleepingComputer webinar with Abnormal AI and Novant Health will show how behavioral AI can help detect abnormal communication patterns, automate investigations, and improve response to Device Code phishing and trusted sender impersonation. #BleepingComputer #AbnormalAI #NovantHealth #DeviceCodePhishing

Cordyceps exposed a CI/CD weakness in GitHub Actions where individually valid workflows combined into exploitable privilege chains, leaving many “green” pipelines vulnerable despite passing scans. The article highlights real cases at Microsoft, Google, and Apache, and argues that AI-generated workflows are accelerating governance gaps that scanners alone cannot catch. #Cordyceps #Microsoft #AzureSentinel #Google #Apache #GitHubActions

Spain’s National Police arrested a man in Palencia suspected of supporting the pro-Russian hacktivist groups CyberArmy of Russia Reborn (CARR) and Z-Pentest. Investigators say he helped a CARR-linked hacker evade capture, coordinated via encrypted apps, and was tied to operations associated with NoName057(16) and attacks on critical infrastructure. #CyberArmyofRussiaReborn #CARR #ZPentest #NoName05716 #APT44 #Sandworm

A Microsoft 365 device code phishing campaign observed in late June and early July 2026 used collaboration-themed lures and a compromised Croatian rental website to trick victims into authorizing attacker sessions through Microsoft’s legitimate device login flow. ZeroBEC and Cisco Talos linked the activity to reusable tooling and PhaaS ecosystems including…

Threat actors are exploiting CVE-2026-48282, a maximum-severity path traversal flaw in Adobe ColdFusion that can lead to arbitrary code execution. Adobe released emergency updates for ColdFusion 2025 and 2023, but exploitation reportedly began within two hours of public disclosure. #AdobeColdFusion #CVE-2026-48282 #KEVIntel #CanadianCentreforCyberSecurity…

CISA is reportedly using Anthropic’s Mythos AI model to scan federal code repositories for security vulnerabilities, with the goal of finding and fixing flaws before adversaries can exploit them. The effort has allegedly already uncovered many bugs, while Anthropic’s broader relationship with US agencies has also faced tension over model safeguards…

A newly disclosed Linux kernel flaw, tracked as CVE-2026-53359 and nicknamed Januscape, can let an attacker escape a KVM virtual machine and execute code on the host. The issue affects shadow MMU code, threatens multi-tenant public clouds, and was demonstrated by Hyunwoo Kim as a zero-day in Google kvmCTF. #CVE-2026-53359 #Januscape…

Tarah Wheeler, CISO at TPO Group, describes a cybersecurity career shaped by social science, writing, and broad hands-on experience across red team, SecOps, compliance, and policy work. She warns that the field lacks reliable ground truth and benchmarks, making it hard to separate facts from hype while leaders like NIST face…

An Iran-linked APT tracked as Cavern Manticore is targeting organizations in Israel with a modular C&C framework that uses .NET compilation formats as an anti-analysis layer. The group, likely tied to Iran’s MOIS and possibly the OilRig subgroup Lyceum, abuses SysAid updates, RMM tools, and remote desktop features to move laterally…

Microsoft is testing Cloud Rebuild in Windows 11 Insider Preview builds, a recovery feature that can remotely reinstall the operating system from the cloud when a device is broken or won’t boot. The feature is part of Microsoft’s Windows Resiliency Initiative and joins Point-in-Time Restore, Quick Machine Recovery, and a new post-BSOD memory scan recommendation to improve Windows 11 recovery and reliability. #CloudRebuild #Windows11 #WinRE #QuickMachineRecovery #PointInTimeRestore

BeyondTrust has patched two critical authentication bypass flaws in its Remote Support and Privileged Remote Access products, warning that exposed instances could let unauthenticated attackers access protected appliances under specific configurations. The company also fixed two high-severity issues, while prior BeyondTrust flaws have been used in attacks against U.S. government systems and linked to #SilkTyphoon and #CVE-2026-1731.

Microsoft will enable the Windows settings backup and restore tool by default on eligible Microsoft Entra-joined and Microsoft Entra hybrid-joined enterprise devices starting with Windows 11 26H2. The change applies only when admins have not already set a policy, while restore remains disabled by default and must still be explicitly configured by IT. #MicrosoftEntra #Windows11 #WindowsBackup

China-aligned attackers breached U.S. and Canadian university networks to steal sensitive data and maintain persistent access through webshells and backdoors. The campaign targeted physics and engineering departments and used Roundcube flaws CVE-2024-42009 and CVE-2025-49113 to gain access, with evidence pointing to the threat cluster UNK_MassTraction and the use of VShell. #UNK_MassTraction #Roundcube #VShell #CVE-2024-42009 #CVE-2025-49113

BeyondTrust has patched four critical flaws in Remote Support and Privileged Remote Access that could let attackers bypass access controls, trigger denial-of-service conditions, or reach unauthorized data under certain configurations. The company said the issues were found internally during security assessments, and users should update immediately to RS 25.3.3 or later…

CERT/CC warned that several Tenda firmware versions contain an undocumented authentication backdoor tracked as CVE-2026-11405, allowing attackers to bypass password checks and gain full administrative access to the web management interface. The flaw is still unpatched, and users are advised to disable remote management and change the default LAN IP address…

Multiple U.S. Army subdomains, including oil.army.mil and ai2c.army.mil, were defaced in a 404 hijacking campaign that displayed pro-Kurdistan messages and insults aimed at President Donald Trump and U.S. Ambassador Tom Barrack.
