Work highlights

After the September 11 attacks, Krebs used public information and newspaper clippings to produce a partial map of the organization behind the attacks.
The resulting paper, , has been called a classic, and "likely the most cited public analysis of the 9/11 network."
After publishing it, he was "invited to Washington to brief intelligence contractors."
Since 2004 Krebs has periodically published infographics showing the political polarization of American book-buying patterns.
He has claimed that the web leads people to narrower, more extreme viewpoints, and suggests cultivating diversity
in social networks,
a process he calls "network weaving".
Krebs has used social network maps to provide evidence of corruption,
help a non-profit group prosecute a slumlord conspiracy,
and visualize the "ecosystem" of fraud in the Bernie Madoff Ponzi scheme scandal.
He has also consulted for corporate clients including IBM and Google.
