A New Zealander reportedly fighting with ISIS goofed up on Twitter. He unknowingly geotagged his tweets from Syria, which embedded GPS data into each post and revealed the secret location of where he's staying.
Mark Taylor, also known as Abu Abdul-Rahman, deleted 45 tweets earlier this week after discovering the problem, The Guardian reports. But it was too late, because Jeff Weyers, who runs open-source intelligence group iBrado, was able to pinpoint Taylor's exact house in al-Taqbah, a Syrian town near an ISIS stronghold.
Taylor's Twitter account is now suspended.
