Microsoft "Patch Tuesday" Includes Eleven Patches, Four of Them Critical

Last Tuesday, Microsoft released their monthly batch of updates. This time there were four critical updates out of eleven total, though many of the updates address multiple vulnerabilities. The most critical of these is MS15-033, which addresses an Office vulnerability that could enable a malicious document to run code on the vulnerable system. It is believed that this flaw is being actively exploited already. The other patch that should be expedited is MS-034, which involves a vulnerability in the IIS web service on Windows 2008R2 and 2012. This flaw is also being actively exploited by attackers to crash web serves on the Internet. If your organization is running a Windows-based web server, consider testing and implementing this patch as quickly as possible.

Adobe Releases Multiple Patches, Including One for a Critical Flash Zero-Day

Last Tuesday, Adobe release security notices for three products, Flash, ColdFusion, and Flex. The Flash vulnerability is critical and it is believed that this vulnerability is being actively exploited on the Internet already. It is possible for a malicious website to run unauthorized code on vulnerable systems if a user visits a malicious website, or even one containing a malicious advertisement.

Oracle Releases a Whopping 98 Security Bulletins, Including Final Java 7 Update

Oracle released a large collection of updates last week for a variety of products, including Java, Oracle, MySQL, and many others. Three of the Java patches are for critical vulnerabilities (CVE-2015-0469, CVE-2015-0459, and CVE-2015-0491), and should be applied as quickly as possible. This update is also the last update that will be made to Java 7; organizations should check to see if they are running Java and upgrade any systems that are to Java 8.

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

Ransomware Observed to Jump from One Device to Another via the Cloud Researchers described last week an incident where they observed malicious "ransomware" propagating from one device to another via cloud-based file synchronization. When the ransomware encrypted files on one machine that synchronized files to a specific folder, it spread to other PCs that synchronized to that same folder. This type of phenomenon is simply another reason for organizations to serious consider limiting or eliminating the use of such file-synchronizing software within their networks. http://www.scmagazine.com/researchers-confirm-cases-of-ransomware-encryption-jumping-devices-via-cloud-apps/article/479572/ New OpenSSL Patches Soon to Come The OpenSSL project team announced last Thursday that they are working on patches to fix at least two "high" severity vulnerabilities in OpenSSL.
