Microsoft promptly released a patch to address the SMB Ghost vulnerability. Ensure that all affected systems are patched to the latest version.\n\n\ud83d\udda5Network Segmentation: Implementing network segmentation can help contain the impact of potential attacks. By isolating critical systems from less secure ones, you reduce the attack surface and limit an attacker's ability to move laterally across your network.\n\n\ud83d\udda5Firewall Configuration: Configure firewalls to restrict access to SMB ports (such as TCP 445 and UDP 445) from external networks. Limiting SMB traffic to only necessary and trusted sources helps prevent unauthorized access.\n\n\ud83d\udda5Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS): Utilize IDS or IPS solutions to detect and block any attempt to exploit the SMB Ghost vulnerability. \n\n\ud83d\udda5User Awareness and Training: Educate users about phishing attacks and social engineering techniques.\n\n\ud83d\udda5Disable SMBv3 Compression: If not strictly necessary, consider disabling SMBv3 compression to mitigate the risk of SMB Ghost attacks. Disabling this feature can prevent potential exploitation.\n\n\u2618Pass: @its_me_kali \n\n\u2661 \u3164\u00a0\u00a0\u00a0 \u274d\u3164\u00a0\u00a0\u00a0 \u2399\u3164\u00a0 \u2332\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \n\u02e1\u1da6\u1d4f\u1d49\u00a0 \u1d9c\u1d52\u1d50\u1d50\u1d49\u207f\u1d57\u00a0 \u02e2\u1d43\u1d5b\u1d49\u00a0 \u02e2\u02b0\u1d43\u02b3\u1d49", "creation_timestamp": "2023-06-14T11:11:15.000000Z"}
