A spamming operation has exposed on a server in the Netherlands gigabytes of files that include 711 million email addresses and some associated account passwords. It’s perhaps the largest batch of email addresses ever found in one spot. Spam operators mistakenly left directory browsing open, which exposed the data. The email addresses are used by a spambot called Onliner, which has been used to send malware called Ursnif, which infects computers and collects online banking credentials. Only 27 percent of the email addresses were “new” in the sense that addresses hadn’t appeared in major breaches.”]
