MICROSOFT WOULDN'T LOOK AT A BUG REPORT WITHOUT A VIDEO

Security researcher Will Dorman attempted to report a vulnerability to the Microsoft Security Response Center by providing a report with a clear description of the bug and supporting screenshots. However, Microsoft responded that it could not review the report until a video was submitted. This was unnecessary and time-wasting, as it would provide no additional details and would just show the commands that have already been screenshotted.

NEW NPM ATTACK POISONS LOCAL PACKAGES WITH BACKDOORS

Researchers at Reversing Labs identified two malicious packages on npm targeting the ‘ethers' package: ‘ethers-provider2' and ‘ethers-providerz.' These packages stand out because they download a secondary malware stage that monitors the legitimate ‘ethers' package, then swaps its ‘provider-jsonrpc.js' with a trojanized version. This trojanized file downloads a third-stage malware that creates a reverse shell to a malicious IP address. Reversing Labs emphasizes the severity of this issue, as removing the malicious package does not eliminate the risk since the trojanized legitimate package can still harbor the malware.

SCALING THREAT MODELING WITH AI: GENERATING 1,000 THREAT MODELS USING GEMINI 2.0 AND AI SECURITY ANALYZER

This blog post presents a method to produce high-quality threat models using Gemini 2.0 Flash Thinking and a series of prompts. The author found that the LLM performed poorly with prompts that were too long or too short but found that they could use multiple prompts that are in a “sweet spot” of length to science the desired results. They then used GitHub Actions to queue repositories into a pipeline that their AI Security Analyzer could then generate security design documentation, threat modeling, attack surface, and attack tree analysis for.

HOW TO HACK AN EIGHT SLEEP SMART MATTRESS “POD”

Security researcher Dylan Ayrey identified three key vulnerabilities in Eight Sleep's "Pod" mattress: a developer backdoor for SSH access, an exposed AWS key, and dependence on cloud services. He replaced the $4,700 hub with a $150 aquarium chiller, demonstrating a simpler solution for temperature control that avoided data collection and internet access, instead of relying on a $200-300 annual subscription.

A SNEAKY PHISH JUST GRABBED TROY HUNT'S MAILCHIMP MAILING LIST

Troy Hunt of Have I Been Pwned recently fell for a phishing email that claimed his Mailchimp privileges were restricted, redirecting him to a site that stole his login and MFA code. The email's legitimacy was convincing, and fatigue combined with Outlook for iOS not displaying the email address contributed to his error. However, 1Password's lack of autofill should have prevented it. Hunt also questioned why Mailchimp kept unsubscribed emails and has added the breached email list to his site.
