LATERAL MOVEMENT - BITLOCKER

BitLocker is a full disk encryption feature for Windows that protects data at rest by encrypting full volumes. This post outlines a privilege escalation or lateral movement technique that uses Windows Management Instrumentation (WMI) to hijack specific COM objects of BitLocker using remote manipulation of BitLocker registry keys to execute code under the user's context on a target host. The post also discusses detection opportunities for this attack and Sigma and Windows Defender for Endpoint queries to detect them.

YASA

YASA (Yet Another Static Analyzer) is an open-source static program analysis project. Its core innovation lies in a unified intermediate representation called the Unified Abstract Syntax Tree (UAST), designed to support multiple programming languages. Built on top of UAST, YASA provides a highly accurate static analysis framework. Users can extend its capabilities by writing custom checkers to perform various program analysis tasks—such as AST queries, data flow analysis, and function call graph analysis—and expose functionality through SDK, declarative query language (QL), or MCP.

MEET SHADOWLEAK: ‘IMPOSSIBLE TO DETECT' DATA THEFT USING AI

Researchers at Radware discovered a vulnerability called ShadowLeak that exploits OpenAI's ChatGPT through indirect prompt injection attacks. Hidden email instructions can trick the AI into stealing sensitive data like credit card numbers and names from users' inboxes. The attack bypasses ChatGPT's security protections by encoding stolen data in Base64 and exfiltrating it directly through OpenAI's servers via the agent's browsing tool, making it nearly impossible to detect since it doesn't go through the client interface. This attack represents a significant escalation from previous client-side prompt injection attacks, as the data theft occurs entirely on the backend without any visible signs to the user.

HOW TO GET CITED IN AI ANSWERS

AI search rewards consistent authority and authentic brand signals. To increase visibility in AI answers, prioritize publishing high-quality, expertise-driven content on your own site or in respected industry publications. Another tactic is to actively participate in conversations on platforms like Reddit, LinkedIn, and niche forums to help AI models pick up real references. Beyond digital efforts, offline tactics such as presenting at industry conferences, collaborating with known influencers, and contributing data-backed research studies create real-world credibility that AI systems can pick up over time.

HOW ALDI REVAMPED ITS SOCIAL MEDIA STRATEGY — AND WHY IT'S WORKING

Aldi has shifted its social media strategy to presenting itself as a persona rather than a store. It's no longer focusing its socials on low prices and instead leans into playful, culturally relevant content and viral trends. This approach has driven double-digit growth in engagement on Instagram and TikTok, with some posts reaching over 600,000 shares and far outperforming competitors like Kroger and Whole Foods. Aldi's small social team, which consists of a manager and two associates, achieved this by staying consistent across platforms while balancing planned content with quick reactions to trends.

10 B2B NEWSLETTER TIPS

B2B newsletters work best as short-form, native content that teaches or inspires rather than just linking to blog posts. Send them consistently, monthly or bi-monthly, and from a real person, not a generic address. Avoid generic titles, focus on the reader, and keep copy skimmable. Reserve pitches for the PS, use images or videos sparingly, and publish on a newsletter platform for extra reach. Split dense content across multiple issues to keep them readable and engaging.

WHAT 3 YEARS AT WIZ TAUGHT ME ABOUT B2B MARKETING

Wiz built its B2B brand by ignoring standard playbooks and adopting high-frequency experimentation. The team launched projects such as a toy store for CISOs and a Kubernetes course taught by puppies, intentionally choosing ideas a traditional enterprise would avoid. These “drops” helped differentiate Wiz in a crowded cybersecurity market and fueled a 10X growth in organic reach. Rather than relying on performance channels, it focused on unpaid attention.

PULL VS. PUSH MARKETING

Push marketing usually shows linear or diminishing returns and requires sustained spend to maintain reach. Pull marketing, by contrast, builds momentum over time but depends on audience discovery and organic engagement. Push efforts can risk brand fatigue and low-quality interactions when overused, while pull tactics may underdeliver without a clear path to distribution.

HOW TO TURN CLAUDE CODE INTO A DOMAIN SPECIFIC CODING AGENT

LangChain developers experimented with improving Claude Code's ability to work with domain-specific libraries like LangGraph and LangChain, rather than just popular libraries. Their main finding was that providing Claude with high-quality, condensed information in a Claude.md file was more effective than just giving it raw documentation access, as the condensed guide outperformed the MCP documentation tools alone. The best results came from combining both approaches: giving the agent base knowledge through Claude.md while also providing tools to access specific documentation when needed.

FETCH STREAMS ARE GREAT, BUT NOT FOR MEASURING UPLOAD/DOWNLOAD PROGRESS

While fetch streams are useful for processing data, they shouldn't be used to measure upload/download progress because they give inaccurate results. This is because they measure when data is buffered rather than actually transmitted over the network. For now, XMLHttpRequest is still the best option for progress tracking, though a new fetch observer API is being developed to properly address this gap.
