Security researchers report a startling rise in attacks against Microsoft Office 365 accounts, how do you keep the hackers out?
Researchers from Barracuda Networks have found that hackers are targeting Microsoft Office 365 accounts with a worrying degree of success. In a report published today, the researchers refer to a “startling rise” in the number of account takeover (ATO) attacks, with an analysis of those aimed at their own customers suggesting 29% of organizations had seen their Office 365 accounts compromised by hackers in March alone. Using these compromised accounts, the hackers were able to send in excess of 1.5 million malicious and spam emails.
