Whistleblower: DOGE Siphoned NLRB Case Data
- A security architect at the NLRB alleges that DOGE employees transferred sensitive data in March using short-lived accounts configured to leave few traces.
- The data outflows coincided with blocked login attempts from a Russian internet address using valid credentials.
- The whistleblower's letter was sent to the Senate Select Committee on Intelligence.
- The NLRB is an independent agency that investigates unfair labor practices and stores sensitive data.
- DOGE officials demanded powerful 'tenant admin' accounts exempt from detailed logging activity.
- The new DOGE accounts had unrestricted access to NLRB databases and the ability to alter information.
- One DOGE account created a virtual environment and transferred approximately 10 gigabytes of data from the NLRB's system.
- Numerous login attempts from a Russian IP address using correct credentials for a DOGE account raised alarm.
- The NLRB launched an investigation but was instructed to drop it, prompting the whistleblower to go public.
- Claims of network anomalies, missing logs, and unauthorized code library downloads further raised suspicions.

TikTok Virtual Machine Reverse Engineering
- The TikTok Virtual Machine (VM) is reverse engineered in this project, focusing on deobfuscating the webmssdk.js file and decrypting its bytecode.
- The VM uses heavy obfuscation techniques like bracket notation indexing and function call disguising, making the code difficult to read.
- By deobfuscating the script and decrypting the XORed bytecode, the functionality of the VM is revealed, showing a sophisticated structure with scopes and nested functions.
- Virtual Machine decompiling involves writing appropriate code for each bytecode instruction, allowing for a form of decompilation to understand the VM's operations.
- Debugging the deobfuscated file involves replacing the original webmssdk.js with the deobfuscated version, enabling normal TikTok usage for testing and analysis.
- Reverse engineering also allows for generating signed URLs for performing authentication-based requests, utilizing functions like VM86, VM113, and VM189 for different headers.
- Special attention is given to understanding the functions of X-Bogus and _signature headers in requests and developing a signer tool for signing URLs appropriately.
- The reverse engineering process uncovers various obfuscation techniques used in the TikTok VM and provides insights into its evolving nature, necessitating ongoing decompilation efforts with each release.

From Repos to Risks: How Hardcoded Secrets in GitHub Source Code Create Security Risks
- Hardcoded secrets in GitHub source code pose significant security risks as developers share code snippets in public repositories, exposing sensitive data like authentication tokens, API keys, and passwords.
- Reasons for leaving hardcoded secrets include simplifying workflows, assumed secure internal repositories, and managing complex CI/CD pipelines.
- Exposed plaintext secrets can lead to unauthorized access when threat actors scan public repositories, potentially compromising services authenticated by those secrets.
- Reports show millions of secrets leaked on GitHub, causing security incidents due to preventable data leaks from hardcoded secrets.
- Detecting hardcoded secrets in large codebases poses challenges for security teams, requiring thorough scanning of source code, configuration files, environment variables, and personal repositories.
- Monitoring repositories for leaked information is essential but time-consuming, necessitating auditing code repositories to prevent data breaches.
- Automated threat intelligence solutions are crucial to scanning the web for compromised credentials, malware-infected devices, leaked source code, and accidental commits containing secrets.
- By augmenting traditional security tools with automated threat intelligence, security teams can enhance visibility and mitigate risks associated with hardcoded secrets outside internal controls.
- To strengthen security against hardcoded secrets in public repositories, organizations need to extend monitoring to clear, deep, and dark web sources to proactively address potential data leaks and unauthorized access.
- Expanding monitoring beyond internal threat surfaces to include public code repositories and illicit channels like Telegram enables security teams to stay proactive and protect against evolving cyber threats.

Seth Michael Larson: Quick Mastodon toot templates for event hashtags
- Mastodon user Seth Michael Larson has shared a quick method for creating pre-populated event hashtag templates for Mastodon toots.
- Larson, a Mastodon fan, wanted a simple way to post about in-the-moment content during the PyCon US 2025 conference, without having to type out all the hashtags each time.
- The solution Larson found was to use pre-filled share URLs that include the desired hashtags in percent-encoded text.
- To make the process work on iOS devices, Larson saved the URL to a GitHub Gist and added the Gist webpage to the home screen.

Why Are Buttons Losing the Pointer Cursor? The ShadCN and Tailwind Debate
- Developers working with ShadCN v4 and Tailwind CSS v4 noticed that buttons no longer showed the pointer cursor on hover, which broke user expectations.
- A Github issue was opened to address this change, but it is actually a deliberate design choice where buttons now use the default cursor by design.
- A custom CSS workaround has been shared by developers to restore the expected behavior and avoid pointer cursors on disabled buttons.
- Originally, GUI buttons relied on visual affordances instead of cursors for interactivity, but web apps have different expectations with users now expecting visual cues like cursor changes for all clickable elements.

Reduce Java Object Size with Field Ordering
- The order of your variables in a class can affect object size, heap usage, and even JVM performance.
- JVM aligns fields like long, int, byte for performance. Misaligned fields result in padding, thereby wasting memory.
- Reordering fields can reduce object size and can be a low-effort, high-impact optimization.
- Follow the order: double, long, int, float, char, short, byte, boolean to minimize memory waste.
