Founder Dominick Skinner believes the “sophisticated” Direct Denial of Service attack, which overwhelmed the site with traffic, may have originated in Russia.
The attack happened after reports that Skinner intended to publish a dataset of approximately 4,500 immigration personnel, obtained from a Department of Homeland Security whistleblower.
The dataset contains names, email addresses, phone numbers and job titles, with Skinner planning to make most of this information public.
The Department of Homeland Security has condemned the website, labelling it “disgusting doxxing” that endangers officers and their families, and has pledged to prosecute those responsible.
