One of the Microsoft Windows vulnerabilities used to spread the Stuxnet worm that targeted Iran remained the most widely exploited software bug in 2015 and 2016 even though the bug was patched years earlier, according to a report published by antivirus provider Kaspersky Lab.
In 2015, 27 percent of Kaspersky users who encountered any sort of exploit were exposed to attacks targeting the critical Windows flaw indexed as CVE-2010-2568. In 2016, the figure dipped to 24.7 percent but still ranked the highest. The code-execution vulnerability is triggered by plugging a booby-trapped USB drive into a vulnerable computer. The second most widespread exploit was designed to gain root access rights to Android phones, with 11 percent in 2015 and 15.6 percent last year.
