Mar. 31st - The Internal Revenue Service issued a warning of an ongoing IRS-impersonation scam that appears to primarily target educational institutions, including students and staff who have ".edu" email addresses.

A vulnerability has been discovered in Exim, which could allow for unauthenticated remote attackers to execute arbitrary system commands on the mail server. Exim is a mail transfer agent used to deploy mail servers on Unix-like systems. Successful exploitation of this vulnerability will enable the attacker to perform command execution as root in the context of the mail server. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
