Are You One of the 533M People Who Got Facebooked?

April 6, 2021

Ne’er-do-wells leaked personal data — including phone numbers — for some 553 million Facebook users this week.

Meanwhile, if you’re a Facebook product user and want to learn if your data was leaked, there are easy ways to find out.

December 18, 2020

U.S. government cybersecurity agencies warned this week that the attackers behind the widespread hacking spree stemming from the compromise at network software firm SolarWinds used weaknesses in other, non-SolarWinds products to attack high-value targets. According to sources, among those was a flaw in software virtualization platform VMware, which the U.S. National Security Agency (NSA) warned on Dec. 7 was being used by Russian hackers to impersonate authorized users on victim networks.
