Office a Target
Earlier this week, Kaspersky Lab said Microsoft Office has become the number one attack target for cybercriminals. The Russian cyber security firm says attacks and exploits on Office products account for 70 percent of all attacks. At the Kaspersky Lab Security Analyst Summit, the company showed data for the fourth quarter of 2018. Office has increasingly become the go-to attack target with the number of attempts four times higher than they were during Q4 2016.
