  • BitMEX Email Leak - an incident report on the massive email address leak affecting BitMEX users. The report identifies an engineering lapse where a SendGrid API call batched sent addresses into a single TO: field which exposed addresses to all other recipients. The report also identifies that exchange’s Twitter account was also briefly compromised. Following the exposure, there were reports on hacking groups starting to target BitMEX users using leaked emails.
