Executive Summary - There were significant updates from Microsoft and Adobe this month as long as a minor update to Java.  The most interesting updates that I've seen thus far address a vulnerability in the Windows Font Library (CVE-2018-1010, -1012, -1013, -1015, -1016).  These could be exploited remotely by an attacker via social engineering attack (phishing, etc.) to get access as the logged-on user and then chained together with a privilege escalation vulnerability (like CVE 2018-1034) to gain administrative or system level access. News Managed Firewall Services - We are considering offering a managed firewall solution and are looking for 3 to 5 clients that would be interested in helping us to pilot the program.  Test sites would need to have a minimum of 5 workstations and a maximum of 10…

February 2018 News and Updates

Monthly Newsletters
Executive Summary - Spectre and Meltdown dominated the news during the last update cycle but seem to be winding down.  The good news here is that strides are being made to mitigate the problem, including a Meltdown and Spectre Detector tool in Microsoft Windows Analytics.  The bad news though is that a number of other critical vulnerabilities in Microsoft Outlook and Adobe Flash Player have stepped up to take the place of Spectre and Meltdown. News DC770 In The News - DEF CON North Atlanta, or DC770, made the front page of the Cartersville Daily Tribune on Wednesday, 6 February 2018.  DC770 is a DEF CON group that meets monthly at Jefferson's in Cartersville.  More information is available at the DC770 website and the article is available at the Daily…

October 2017 News and Updates

Updates Executive Summary - This month's dominate tech news story had headlines warning us that "'All Wi-Fi networks' are vulnerable" . Security researcher Mathy Vanhoef of imec-DistriNet, discovered a vulnerability in the WPA2 standard that has been dubbed KRACK (Key Reinstallation Attacks) and according to the researcher "works against all modern protected Wi-Fi networks." The attack is particularly devious in that it allows not only for things like "steal[ing] sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on" but also can allow the attacker to "inject ransomware or other malware into websites". The paper goes on to say that "if your device supports Wi-Fi, it is most likely affected. " Also this month, using Shodan, a search engine for Internet-connected devices, we are able…

Updates Executive Summary - In addition to the normal Microsoft, Adobe and Oracle / Java updates, Google released an update to patch 10 critical bugs in the Android operating system and Mozilla released an update to patch 29 vulnerabilities in Firefox including making Adobe Flash objects Click-To-Enable.  The excitement from WannaCry and Petya / Not-Petya seems to be calming down but it looks like the Mamba ransomware (gained fame in the end of 2016 by taking the San Francisco transit system offline) seems to be making a comeback.  It only seems to be impacting Saudi Arabia and Brazil at the moment but it would be wise for blue teams to take note and make sure that you're ready (Are you all patched up?  Network segmented to minimize the damage of…

July 2017 News and Updates

Monthly Newsletters
Updates Executive Summary - 2017 has been an explosive year for ransomware and a wake-up call for administrators of the importance of installing updates in a timely fashion.  The WannaCry virus in May wreaked havoc when it took advantage of an already patched bug in Microsoft Windows.  The Petya and Not Petya viruses struck in June, leveraging the same already patched vulnerability. Microsoft - Microsoft patched a total of 54 vulnerabilities this month in Windows, Edge, Internet Explorer Office and Exchange, 19 of which were rated critical, 32 rated important and three rated as moderate.  Several of the critical vulnerabilities are remotely exploitable and could give an attacker full control with little or no action on the part of the user. Microsoft releases regular updates the second Tuesday of each…

   Updates Executive Summary - 2017 is starting out with a relatively low number of updates with only four bulletins from Microsoft (Edge, Office and Windows [LSA]) and two updates from Adobe (Flash, Acrobat & Reader) but all resolve issues that could allow an attacker full access (remote code execution or RCE) to vulnerable systems.   Microsoft - Microsoft released 4 bulletins this month (MS17-001 through MS17-004). The bulletins affect Microsoft Edge (oddly enough, nothing mentioned about Internet Explorer), Microsoft Office, Adobe Flash and an internal component of Windows called LSA (Local Security Authority).  The bulletins for Microsoft Office and Adobe Flash Player are rated critical and allow remote code execution (RCE) and the bulletins for Microsoft Edge and LSA are rated important allowing privilege escalation and denial of service respectively.  Multiple…

   Updates Executive Summary - Microsoft released a total of 10 bulletins, most of which are rated critical and most of those can allow an attacker full access to a vulnerable computer remotely (remote code execution, or RCE).  Once again, the first two bulletins address vulnerabilities in Internet Explorer and Edge (Edge is supposed to be a completely separate product from Internet Explorer, but the two seem to share a lot of similar vulnerabilities).  Adobe has patched an impressive 81 vulnerabilities in it's product line (including Acrobat, Reader and Flash, most notably) with several of those listed as critical with successful exploitation leading to remote code execution.   Microsoft - Microsoft released 10 bulletins this month (MS16-118 through MS16-127). Six of the 10 are rated critical, one is rated moderate (information disclosure)…

   What's New DC770 - A quick reminder that DC770 meets the first Tuesday of each month at 7:00pm EDT in the basement at Jefferson's. Updates Executive Summary - This month's Microsoft updates looked oddly familiar to last month, with the descriptions of many of the issues patched sounding eerily similar to last month, which as you may remember was a particularly "exploitable" month of updates. As always, it is extremely important for all available updates to be installed as soon as possible. Adobe is back on the   Microsoft - Microsoft released 14 bulletins this month (MS16-104 through MS16-117). Seven of the 14 are rated critical and the remaining are rated important (by Microsoft).  It should come as no surprise that updates for Internet Explorer and Edge are leading the pack (again)…
