Microsoft issued a patch for the flaw, documented as CVE-2010-2568, back in 2010.
Data from anti-virus company Kaspersky showed that almost a quarter of Windows users who experienced a threat to their systems in 2016 were faced by exploits of this flaw.
It said that the release of the recent batch of CIA exploits by Shadow Brokers had shown that the life of an exploit did not end once a patch was released to fix the vulnerability that it used.

- In 2016 the number of attacks with exploits increased 24.54%, to 702,026,084 attempts to launch an exploit.
