Credit Unions Serving Malicious Ads. Equifax issues continue this week, with one of their ad providers serving malware. While it is true that Equifax itself was not hacked, this further erodes trust if their supply chain is putting visitors at risk. Not to be left out, Transunion was also noticed to have the same problem.

KnockKnock (but quietly). A brute force attack (but a sneaky one) against Office 365 accounts was discovered by researchers. KnockKnock, as it is called, was a targeted attack against a specific set of accounts for a specific set of companies using Office 365.

Attackers also singled out senior and/or long term employees, perhaps hoping they would be more likely to have access to sensitive information.

Disqus customer data exposed. Company promptly addresses. Disqus was made aware customer data being available this week, compromising 17.5 million accounts from 2007 to 2012. Overall, the company has excelled in their response. In under 24 hours, Disqus had accepted a report, validated the findings, reset user passwords and contacted customers. Their expedient behavior and transparency has blown away Troy Hunt, owner of HaveIBeenPwned.com and overall raised the bar for how to handle breach disclosures. Of course, user’s should make sure they are not reusing their passwords, which would leave them open to a credential stuffing attack.
