Oversecured guide to SDK security in mobile apps, built around Microsoft's April 2026 disclosure of an intent redirection flaw in EngageLab's EngageSDK (50 million installs, fixed in 5.2.1). It covers SDK attack surfaces (exported components, WebViews, deep links, hardcoded secrets, payment crypto), a canhub image cropper file-overwrite example, why source-only SAST misses SDK code, and MASVS and PCI DSS expectations.

Microsoft blog post introducing "Risk Management for Open-Weight Models in Enterprise", a joint Microsoft–NVIDIA paper. It proposes a shared risk taxonomy (Cybersecurity, Data Protection, Content, Human-AI Interaction, Bias) grounded in ISO standards and the NIST AI RMF. The paper maps evaluations to risks as evidence and argues that risk depends on the model, use case, deployment and safeguards, not on weight openness alone. It also covers how responsibility for controls shifts when enterprises self-host models, and points to a joint repository of evaluations. The first paper focuses on the model layer; runtime, harness and application layers are planned for later.

It introduces SharpRMS, a custom C# tool that speaks the AD RMS SOAP protocol to enumerate clusters and rights-policy templates, and shows how local AD RMS Service Group membership (not Domain Admin) gates the administrative surface where the SLC private key can eventually be reached — setting up Part 2's key extraction and offline decryption.

Socket announces extension security coverage for Microsoft Edge Add-ons and discloses research into 18 malicious Chrome extensions and one Edge extension delivering an extensible malware framework. Five extensions were purchased from legitimate developers and turned malicious via updates; the framework included 16 modules covering a multi-chain wallet drainer, Ledger/Trezor recovery-phrase phishing, credential/form theft, crypto exchange session harvesting, CSP-header stripping, and a persistent WebSocket C2 channel. The Edge version of "Enable Right Click & Copy — Smart Unlock + OCR" remained live and received a new C2 domain even after the Chrome listing was removed.

Huntress details five modern phishing techniques that bypass traditional "check the URL" training and MFA: ClickFix (fake CAPTCHA tricking users into running Win+R/paste commands to execute malware), Browser-in-the-Browser (fake HTML popup windows mimicking OAuth login prompts with forged address bars/padlocks), ConsentFix (dragging an identity icon to leak an OAuth authorization code that attackers trade for Microsoft Entra ID access/refresh tokens), device code phishing (abusing the legitimate microsoft.com/devicelogin flow to authorize an attacker's device via a code, seen weaponized in PhaaS kits like EvilTokens), and fake video-conference (Teams/Zoom/Google Meet) waiting-room overlays that push a malicious "driver update" install. Each section explains why the technique defeats standard security-awareness training and how Huntress's simulated phishing scenarios replicate it.

A Huntress detection engineer describes using an LLM to analyze a Microsoft 365 account-takeover case: the model flagged an app identifier as malicious, but it turned out to be the legitimate Outlook desktop client (present in 17%+ of customer orgs) — a scoping error caused by comparing against the wrong denominator. Rescoping the same query correctly surfaced the actual malicious tooling (an identifier seen in only three orgs, rewriting inbox rules), which shipped as a live detection rule with true positives and no false positives so far. The piece generalizes this into a framework for delegating detection-engineering work to AI: only hand over tasks you can cheaply and reliably verify, and invest in building fast, repeatable checks (coverage checks, alert-volume checks, known-good/known-bad tests) rather than trusting raw LLM output.

Varonis Threat Labs disclosed RovoBlast, a one-click vulnerability in Atlassian's Rovo enterprise AI assistant where a crafted link using the rovoChatPrompt URL parameter seeded attacker-controlled instructions directly into a victim's live chat session, no jailbreak or permission bypass required. Because Rovo trusted externally supplied parameters and its ResearchAgent tool could autonomously browse and exfiltrate data, a single seeded link let attackers pull sensitive Confluence, Jira, and SharePoint content out to the open web in one automated chain. Atlassian patched the issue before the DEF CON talk and Varonis blog write-up were published; researchers frame the class as "parameter-to-prompt" (P2P) injection, having previously found the same pattern (dubbed Reprompt) in Microsoft Copilot.

After LSHIY's takedown the actor pivoted to FranTech IPv6 ranges and Tor exit nodes; mitigations include disabling ROPC, restricting Azure CLI for non-admins, and enforcing unscoped Conditional Access covering all users, apps, and client types.

An analysis of npm v12 (shipping ~July 2026, previewable on npm 11.16.0+), which flips three dangerous defaults to deny-by-default: automatic preinstall/install/postinstall lifecycle scripts, git dependencies (now requiring --allow-git), and remote HTTPS tarball dependencies (now requiring --allow-remote). The author, a DEF CON speaker on install-script abuse, argues the changes are genuinely good but warns that widespread legitimate use of install scripts (esbuild, sharp, core-js, puppeteer, node-gyp native builds) will drive developers toward reflexive npm approve-scripts approval, and that attackers will simply relocate payload execution outside npm's visibility (curl|bash in install.js, bootstrap binaries), citing DPRK actors' continued abuse of VSCode tasks files even after Microsoft disabled task.allowAutomaticTasks by default. It also surveys complementary controls gaining traction across the ecosystem: npm's min-release-age cooldown (following pnpm's minimumReleaseAge, Yarn's npmMinimalAgeGate, and Bun) and package-firewall products (Datadog's supply-chain-firewall, Liran Tal's npq, Socket, Aikido, Endor Labs).
