This vulnerability allows attackers to steal sensitive login information using a new technique. Introduction. This service is universally available for Windows systems, and legacy versions of SMB protocols could allow a remote attacker to obtain sensitive information from affected systems. Whereas the great vulnerability originally created by Windows file sharing was that hackers could perhaps gain remote access to the contents of hard disk directories or drives, the default exposure of the Internet server Microsoft silently installed into every Windows 2000 system (where port 445 first appeared), allows malicious hackers to. Eternalblue | The NSA-developed Exploit That Just Won’t Die You will undoubtedly recall the names Shadow Brokers, who back in 2017 were dumping software exploits widely believed to be stolen from the US National Security Agency, and WannaCry, the notorious ransomware attack that struck only a month later. This vulnerability was discovered on May 29,2020, after investigating the vulnerability, the experts named it Lucifer, and this malware is capable in conducting DDoS attacks, and it is very well known for all kinds of exploits against different vulnerable Windows devices. The tag 'impact' of plugin "Microsoft Windows SMB/NETBIOS NULL Session Authentication Bypass Vulnerability" says that: "Successful exploitation could allow attackers to use shares to cause the system to crash. To exploit the vulnerability against a client, an unauthenticated attacker would need to configure a malicious SMBv3 server and convince a user to connect to it,” Microsoft notes in an advisory. The user passwords are stored in a hashed format in a registry hive either as a LM hash or as a NTLM hash. This method attacks via the NEGOTIATE PROTOCOL REQUEST which is the first SMB query sent.
