“it is not unusual for internet services that serve customers to be focused by this type of activity, which typically involves bad actors testing massive numbers of already compromised credentials from different platforms to peer if users have reused them elsewhere. This sort of attack normally does no longer affect our big organization clients that use their single signal-on systems. We’ve already employed multiple intelligence firms to locate those password dumps and the tools used to create them, as well as a company that has shut down hundreds of websites trying to trick users into downloading malware or giving up their credentials. We continue to investigate, are locking accounts we’ve observed to be compromised, asking users to change their passwords to something more secure, and are searching at implementing new technology solutions to reinforce our efforts.”
