The CIA is planting web beacons inside Microsoft Word documents to track whistleblowers, journalists and informants, according to WikiLeaks.

WikiLeaks released details on what it said is a Central Intelligence Agency document tracking program called Scribbles, part of the agency’s effort to keep tabs on documents leaked to whistleblowers and journalists. Scribbles allegedly embeds a web beacon-style tag into watermarks located on Microsoft Word documents that can report document analytics back to the CIA.

WikiLeaks released information Friday about Scribbles as part of its ongoing Vault 7 Dark Matter release that began last month. Also released is what WikiLeaks said is Scribbles’ source code.
