One would think that once a vulnerability received ample coverage and explicit warnings that encouraged uses to patch, we might see a drop-off in attacks. That is not the case; however, as Microsoft is again reporting that the Zerologon security flaw is still being exploited in the wild. This is another succinct warning on top of the pile already saying that Zerologon is dangerous, and people need to patch their systems ASAP. In late September, we reported, as others did, that hackers were actively exploiting the Zerologon security flaw. Following a Department of Homeland Security emergency directive, Microsoft confirmed that they were tracking the use of Zerologon. Microsoft also reported that...

There is a very good reason why the Department of Homeland Security recently issued an emergency directive to federal agencies to patch their Windows Servers against Zerologon. Just five days after the directive, Microsoft confirmed on Twitter that Zerologon is actively being exploited by hackers. "Microsoft is actively tracking threat actor activity using exploits for the CVE-2020-1472 Netlogon EoP vulnerability, dubbed Zerologon. We have observed attacks where public exploits have been incorporated into attacker playbooks," Microsoft warned. Zerologon is serious threat affecting Windows Server systems that is rated a 10 out of 10 on the Common Vulnerability Scoring System (CVSS). Left unpatched,...

Earlier in the week, we reported on a dangerous exploit with Windows domain controllers called Zerologon. Now, the Cybersecurity and Infrastructure Security Agency (CISA), under the Department of Homeland Security direction, is issuing warnings about the exploit and is pushing government agencies to patch the vulnerability over the weekend. The Zerologon exploit is a way for a nefarious person to escalate privileges within a system and gain access to other systems and files. It takes advantage of the Windows Server Netlogon Remote protocol and authentication to capture session data to escalate the exploit further. Earlier in August, Microsoft released a patch to mitigate the vulnerability for...

Secura digital security advisors and researchers, have discovered a highly critical vulnerability with Active Directory domain controllers. Rated as a 10 of 10 on the Common Vulnerability Scoring System (CVSS), this exploit, dubbed Zerologon, allows nefarious people to take over the domain controller and execute privilege escalations. The Zerologon exploit takes advantage of how the Netlogon Remote Protocol works. Typically, this protocol is used for machine and user authentication, as well as updating passwords within a domain. To utilize this exploit, one only needs to set up a TCP connection to the domain controller (DC) and you can spoof a client to go from there. This client spoofing works...
