An anonymous reader quotes an exclusive report from The Verge: In late July, Snap's director of engineering emailed the company's team in response to an unfolding privacy threat. A government official from Dorset in the United Kingdom had provided Snap with information about a recent attack on the company's users: a publicly available list, embedded in a phishing website named klkviral.org, that listed 55,851 Snapchat accounts, along with their usernames and passwords. The attack appeared to be connected to a previous incident that the company believed to have been coordinated from the Dominican Republic, according to emails obtained by The Verge. Not all of the account credentials were valid, and Snap had reset the majority of the accounts following the initial attack. But for some period of time, thousands of Snapchat account credentials were available on a public website. According to a person familiar with the matter, the attack relied on a link sent to users through a compromised account that, when clicked, opened a website designed to mimic the Snapchat login screen.
