Microsoft today finally released an emergency software update to patch the recently disclosed very dangerous vulnerability in SMBv3 protocol that could let attackers launch wormable malware , which can propagate itself from one vulnerable computer to another automatically. The vulnerability, tracked as CVE-2020-0796 , in question is a remote code execution flaw that impacts Windows 10 version 1903 and 1909, and Windows Server version 1903 and 1909. Server Message Block (SMB), which runs over TCP port 445, is a network protocol that has been designed to enable file sharing, network browsing, printing services, and interprocess communication over a network. The latest vulnerability, for which a patch update ( KB4551762 ) is now available on the Microsoft website, exists in the way SMBv3 protocol handles requests with compression headers, making it possible for unauthenticated remote attackers to execute malicious code on target servers or clients with SYSTEM privileges. Compre

Shortly after releasing its monthly batch of security updates , Microsoft late yesterday separately issued an advisory warning billions of its Windows users of a new critical, unpatched, and wormable vulnerability affecting Server Message Block 3.0 ( SMBv3 ) network communication protocol. It appears Microsoft originally planned to fix the flaw as part of its March 2020 Patch Tuesday update only, but, for some reason, it pulled the plug at the last minute, which apparently did not stop a tech company from accidentally leaking the existence of the unpatched flaw. The yet-to-be patched flaw (tracked as CVE-2020-0796 ), if exploited successfully, could allow an attacker to execute arbitrary code on the target SMB Server or SMB Client. The belated acknowledgment from Microsoft led some researchers to call the bug " SMBGhost ." "To exploit the vulnerability against an SMB Server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

The US-CERT has released a joint technical alert from the DHS and the FBI, warning about two newly identified malware being used by the prolific North Korean APT hacking group known as Hidden Cobra. Hidden Cobra, often known as Lazarus Group and Guardians of Peace, is believed to be backed by the North Korean government and known to launch attacks against media organizations, aerospace, financial and critical infrastructure sectors across the world. The group was even associated with the WannaCry ransomware menace that last year shut down hospitals and businesses worldwide. It is reportedly also linked to the 2014 Sony Pictures hack , as well as the SWIFT Banking attack in 2016. Now, the Department of Homeland Security (DHS) and the FBI have uncovered two new pieces of malware that Hidden Cobra has been using since at least 2009 to target companies working in the media, aerospace, financial, and critical infrastructure sectors across the world. The malware Hidden Cobra is
