Ingenious. A gripping detective story, with the plot devised by @XBOW, and told by @pwntester.
XBOW pulled off the perfect digital heist: stealing files by hiding them in plain sight. Disguised arbitrary file content as satellite imagery pixels. TiTiler processed the "images" while XBOW extracted secrets from the compression data. Mission details:

You gotta love @XBOW's persistence! The full trace, with every thought and action of @XBOW, is at the end of the post.

XXXXS: Xcellent Xploits: Xbow, Xai+Sonnet! @xai @AnthropicAI.
@Xbow . and that's how coincidences work: just a day after the Sonnet / Gemini Alloy post was published, the eval data from #Grok4 comes in:. - It beats the Sonnet / Gemini alloy (58% to 55%).- But gets even better when alloyed with Sonnet itself to a mind-blowing 67%
