TAKING SHELLTER: A COMMERCIAL EVASION FRAMEWORK ABUSED IN- THE- WILD

Elastic Security Labs found threat actors using an illicit version of SHELLTER, a red team evasion framework, since April to deploy infostealers like LUMMA, RHADAMANTHYS, and ARECHCLIENT2. The malware uses advanced evasion techniques such as polymorphic code, API hooking bypasses, indirect syscalls, memory scan evasion, and AMSI bypass, resulting in low detection rates. Elastic issued a dynamic unpacker and YARA rules to help detect SHELLTER samples, which are spread via YouTube comments and phishing campaigns targeting content creators.

ABUSING CHROME REMOTE DESKTOP ON RED TEAM OPERATIONS: A PRACTICAL GUIDE

Red team operators can abuse Chrome Remote Desktop as a legitimate remote access tool by installing the MSI package with admin privileges and using an undocumented `--pin=111111` parameter to bypass GUI PIN setup requirements. The technique leverages Google's infrastructure and HTTPS/WebRTC protocols, making it more difficult to detect than traditional remote access tools, as it appears as legitimate Google traffic. Defenders should implement application allowlisting solutions, such as AppLocker, and monitor for "Chrome Remote Desktop Host" installations to prevent unauthorized remote access deployments.

HOW TO BUILD AN IRL EVENTS STRATEGY

In-person events can be powerful marketing tools, but only if they align with a startup's audience, go-to-market motion, and existing strengths. Events should be evaluated like any other marketing channel, using clear frameworks that consider fit, expected ROI, and whether the team has the right resources to execute well. Success depends on treating events as full campaigns, with strong creative, content, and follow-up. Coverage and composition are key to choosing the right events: high coverage brings reach, while high composition ensures relevance. Events fail when handled by the wrong people, are overly sales-driven, or lack brand alignment, so thoughtful planning and execution are critical.

HOW ALAMO DRAFTHOUSE MADE GOING TO THE MOVIES COOL AGAIN

By 2012, it ran Austin's three highest-volume restaurants and reported over $12 profit per person, far exceeding traditional theaters. Its acquisition by Sony in 2024 confirmed its lasting influence, as it continues to thrive by building local communities around film rather than copying industry trends.
