As of July 2, security ratings company Bitsight had found that there was a 17 percent decrease in systems vulnerable to BlueKeep, indicating some progress in the patching of systems. However, "approximately 805,665 systems remain online that are vulnerable to BlueKeep," Bitsight had indicated in its July 17 blog post.
Currently, there exists a BlueKeep "working exploit" developed by the U.S. Department of Homeland Security, as well as one developed by the "private sector," Bitsight indicated. Bitsight recommended applying Microsoft's patches and removing the exposure of systems to Internet access.
