A cybersecurity researcher has discovered nearly two million terrorist watchlist records, including "no-fly" list indicators, which were left exposed online last month. The US Department of Homeland Security (DHS) did not remove them until three weeks later.

Cybersecurity researcher Bob Diachenko came across a plethora of records that were exposed online. "On July 19, I discovered a terrorist watchlist containing 1.9 million records online without a password or any other authentication required to access it," Diachenko said in a LinkedIn post on Monday.

The watchlist came from the Terrorist Screening Centre (TSC), a multi-agency group administered by the FBI. "The TSC maintains the country's no-fly list, which is a subset of the larger watchlist. A typical record in the list contains full name, citizenship, gender, date of birth, passport number, no-fly indicator, and more," he wrote.

The cyber security researcher reported the matter to the Department of Homeland Security, which acknowledged the incident. "The DHS did not provide any further official comment, though," he said.
