Microsoft Releases Eight Patches for June, Addressing Twenty Critical Vulnerabilities

Last Tuesday, Microsoft issued eight patches, two of which are rated as critical. The most significant is MS15-056, which is a patch for Internet Explorer (versions 6, 7, 8, 9, 10, and 11!) This patch addresses a number of serious memory corruption vulnerabilities in IE which could potentially allow for a remote code execution exploit. The other critical update, MS15-057, updates Windows Media Player and fixes a some similar memory corruption issues there. This update has a lower "exploitability" rating than the IE fix, but both should be tested and deployed as quickly as possible.

Adobe Releases New Flash Version, Fixes Critical Vulnerabilities

Adobe released updated versions of its Flash Player and AIR products. These updates are critical and address vulnerabilities that could lead to arbitrary remote code execution. The new version of Flash is 18.0.0.160. Google Chrome's built-in Flash will auto-update for most installations, as will Internet Explorer on Windows 8. Internet Explorer on earlier versions of Windows, as well as Firefox, will need manual intervention. If your organization has a managed deployment of Chrome, be certain that the latest version with the updated Flash Player is deployed. You can check the installed Flash version here: https://www.adobe.com/software/flash/about/

VMWare Issues Patch for Critical Vulnerability

VMWare issued a patch last week to a critical vulnerability in its products that run on top of Windows, which could allow an attack to "escape" from one virtual machine to others or to the host machine. This vulnerability does not affect ESX Server or VMWare's other enterprise-class virtual server hosting platforms.
Patches are available for VMware Workstation, VMware Player, and the VMware Horizon Client for Windows.

Major Media Websites Caught up inNew Malicious Advertising Attacks Last week multiple major advertising networks, including Google's DoubleClick, AppNexus, Rubicon, and AOL were abused by attackers to serve up malicious advertisements on major media sites. These malicious advertisements were redirecting to the "Angler" exploit kit, which uses multiple means to attempt to compromise a browser and install malware. While such malicious ads are common on smaller websites, they are not unheard-of on major media sites. This outbreak, however, was unusually large and long-lived, lasting at least the better part of two days. Given how common malicious web ads are, some security experts are recommending the use of ad blocking technology in web browsers. http://www.computerworld.com/article/3044565/security/advertising-based-cyberattacks-hit-bbc-new-york-times-msn.html Malicious Macros in Word Documents Used to Install Malware with No Files Needed Everything old is new a

FBI Sees Massive Increase in Espionage, Including Industrial Espionage, Against the US The FBI on Thursday issued a press release discussing what they believe is an increasing threat of economic espionage against US companies. They estimate that such espionage may cost the US as much as "hundreds of billions" of dollars a year. This espionage is not just directed against large industrial companies, but any place where trade secrets and innovations might be found, including third-party organizations (e.g. business partners, vendors, consultants, lawyers, etc.) affiliated with targeted companies. A key take-away is that the threat is more widespread than most people think, and that few organizations are immune. https://www.fbi.gov/news/pressrel/press-releases/fbi-announces-economic-espionage-awareness-campaign http://www.cnn.com/2015/07/24/politics/fbi-economic-espionage/ Microsoft Releases Out-of-Cycle Patch for Critical Font Driver Bug A flaw uncovered in connecti

Critical Vulnerability Discovered in IIS 6.0 Web Services

Image
IIS 6, the version that runs on Windows 2003 Server, was revealed this week to have a serious vulnerability that could allow an attacker to run malicious code on the server. The vulnerability has apparently been known to some malicious groups for some time, as attacks exploiting this vulnerability have been observed as far back as summer of 2016. But last week a proof-of-concept exploit for the vulnerability was posted to GitHub, bringing public attention to the problems and providing potential attackers with a head start on developing their own exploit code.  That is likely to take this from a secretive exploit used by a few actors to one that will be widely used by many attackers, meaning anyone running a vulnerable server is a likely victim. Vulnerability announcements are common, but this one is especially problematic for several reasons: IIS 6.0 is a part of the Windows 2003 Server operating system, which aged out of support from Microsoft almost two years ago. There are an
