SANs Institute lost 28,000 records of PII
On Aug 6, 2020, the SANS Institute reported a data incident that caused 513 employee emails from Microsoft Outlook 365 to be forwarded to an unknown external email address. SANS Institute specializes in information security, cybersecurity training, and selling certificates. The exposed emails contained 28,000 records of customer personally identifiable information (PII). The data incident was caused by a phishing email that maliciously gave an O365 Add-In access to forward emails to a 3rd party. A representative at SANS stated, “We have identified a single phishing email as the vector of the attack. As a result of the email, a single employee’s email account was affected. Aside from the affected user, we currently believe that no other accounts or systems at SANS were compromised. ”
They stated affected parties have been notified by email and no passwords or account information was lost. You can read more about the incident here.
