“While the number of bait attacks is still low overall, they are not unusual. Based on analysis by Barracuda researchers, just over 35% of the 10,500 organizations analyzed were targeted by at least one bait attack in September 2021, with an average of three distinct mailboxes per company receiving one of these messages.” Said Olesia Klevchuk from barracuda.
