schwit1 quotes a report from Zero Hedge: As the latest installment of it's "Vault 7" series, WikiLeaks has just dropped a user manual describing a CIA project known as "Scribbles" (a.k.a. the "Snowden Stopper"), a piece of software purportedly designed to allow the embedding of "web beacon" tags into documents "likely to be stolen." The web beacon tags are apparently able to collect information about an end user of a document and relay that information back to the beacon's creator without being detected. Per WikiLeaks' press release. But, the "Scribbles" user guide notes there is just one small problem with the program: it only works with Microsoft Office products. So, if end users use other programs such as OpenOffice of LibreOffice then the CIA's watermarks become visible to the end user and their cover is blown.
