They DKIM here, they DKIM there
A huge phishing campaign exploited a security blind-spot in Proofpoint's email filtering systems to send an average of three million"perfectly spoofed" messages a day purporting to be from Disney, IBM, Nike, Best Buy, and Coca-Cola – all of which are Proofpoint customers.
The spam campaign ran from January to June, and at peak times reached 14 million dodgy emails within a 24-hour period, according to Guardio Security, which notified security tool maker Proofpoint in May about the exploitable weakness and assisted with subsequent mitigation efforts.
Simply put, the miscreants just needed to spam out mail from one or more rogue SMTP servers and have it forward relayed via their own Microsoft 365 tenant accounts to Proofpoint. Or as Guardio explained, the routing feature was not secure by default, needed some fiddling with settings to shore it up, and Proofpoint's customers didn't realize this."There are ways to add specific rules to Proofpoint account to prevent this and other kinds of spoofing by manually filtering emails from unknown sources and other specific headers and properties.
