Spambot harvested 711 million email addresses

A security researcher in Paris recently discovered an open web server with dozens of text files containing a massive cache of data, ZDNet reported.

The files contained email addresses, passwords, and email servers used to send spam.

The researcher said a spambot, called “Onliner”, was being used to deliver the banking malware Ursnif to inboxes around the world.

It has already resulted in over 100,000 unique infections globally, said the researcher.

The security researcher wrote about the mechanics of the Onliner spambot on his blog, highlighting it as a good example of why you should not open spam.

Troy Hunt, founder of Have I Been Pwned, also recently wrote about the spambot and the data it contained.

The data has been loaded into Have I Been Pwned, alerting users to email address likely to receive the Ursnif malware.
