A overview of the Catwatchful database lists Charcov as the primary document in one of many recordsdata within the dataset. (In previous spyware-related knowledge breaches, some operators have been recognized by early information within the database, as oftentimes the builders are testing the adware product on their very own units.)
The dataset included Charcov’s full title, cellphone quantity, and the net tackle of the particular Firebase occasion the place Catwatchful’s database is saved on Google’s servers.
Charcov’s private e mail tackle, discovered within the dataset, is identical e mail that he lists on his LinkedIn web page, which has since been set to personal.
