The Department of Homeland Security has added its voice to a chorus of government and corporate cybersecurity professionals urging users to patch their systems for BlueKeep, a critical vulnerability recently reported in old Microsoft Windows operating systems. DHS’s Cybersecurity and Infrastructure Security Agency said Monday said it had used the BlueKeep vulnerability to execute remote code on a test machine operating Windows 2000. The agency released an advisory reiterating that, like the famed WannaCry ransomware, BlueKeep is “wormable,” in that malware exploiting the vulnerability could spread to other systems. The BlueKeep vulnerability, for which Microsoft published an advisory on May 14, could allow a hacker to abuse the popular Remote Desktop Protocol, which grants remote access to computers for administrative purposes, to delete data or install new programs on a system. When it was disclosed, security experts immediately warned of BlueKeep’s severity, and as of last week, close to 1 million internet-exposed machines were still vulnerable […]

Weeks before the WannaCry ransomware spread like wildfire through unpatched Windows systems, a more sophisticated, stealthier attacker used the same NSA-engineered cyberweapon to infiltrate the IT networks of companies across the world, including at least one publicly traded in the U.S., according to new research. So stealthy was the fileless, in-memory attack, which hides itself inside the activity of a legitimate application, that it evaded five different security products running on the infected system, Gil Barak, CTO of Israeli cybersecurity firm Secdo told CyberScoop. Those products included so-called “next generation” filters that don’t rely on known signatures, he said. “Not only did they not stop the attack, they couldn’t even see it,” he said. Attackers using the technique “can pretty much do what they want, unnoticed — and then vanish.” Barak wrote a blog post on the attack and appeared with noted security researcher Jake Williams on a webcast this week where the two discussed the […]
