We combined OSINT with traditional reporting to get this story. And it's out today. This is an uncommon story in the Brazilian Amazon: Black and Indigenous communities that kicked out a palm oil company from what used to be their traditional land, and won https://t.co/3E5iOF1aUs

🇵🇸 Israel Exposed, the anonymous collective behind one of the largest online archives of Gaza genocide documentation, has released a map placing more than 35,200 videos and photos at the locations in Gaza where they were filmed.

Every geolocated clip links to its original post and source. Users can filter by area, date and type of attack, and overlay UN satellite damage assessments (UNOSAT). The full dataset is downloadable.

The group launched its archive in July with more than 64,500 videos and 17,900 photos and says more footage will be added.

For years, drones have surveilled law enforcement along the US-Mexico border.

Now, as the US tries new ways to counter drones, we've analyzed hundreds of videos, reviewed detection data, and gone to Texas to show how cartels and criminal groups use them.

A group of AI bots colluded for months and autonomously hacked another company—providing a new, serious reason to worry about the dangers of AI and the recklessness of the companies building it, @matteo_wong reports: https://t.co/R5bFmlY1lJ

Narratives about a “censorship-industrial complex” spread in right-wing circles for years; then they took hold of Washington. What—and who—is behind them? https://t.co/RhBdnBPhee

[Gisela Pérez de Acha @giselilla]

Our new story on how the "censorship industrial complex" jumped from fringe to policy is live on @techreview and @typeinvestigate.

Using OSINT methods, we scraped right-wing sites, sifted hundreds of thousands of records, and analyzed 100k+ posts https://t.co/hdQWyo9b9p

I ran the @bellingcat challenges this month and OMG

The AI era is confusing for open source researchers. Most of this month's challenges lean straight into that (along with other "edits" that you have to spot)

Let us know how you solved them
