Microsoft investigates the current threat landscape
Posted on 17 May 2011.
Microsoft published volume 10 of the its Security Intelligence Report (SIRv10) which provides perspectives on software vulnerabilities, software vulnerability exploits, malicious and potentially unwanted software, and security breaches in both Microsoft and third party software.


Microsoft found out that vulnerabilities in applications versus operating systems or web browsers continued to account for a large majority of all vulnerabilities in 2010, although the total number of application vulnerabilities declined 22.2 percent from 2009.

Industry vulnerability disclosure trends continue an overall trend of moderate declines since 2006. This trend is likely because of better development practices and quality control throughout the industry, which result in more secure software and fewer vulnerabilities.


The exploitation of Java vulnerabilities sharply increased in the second quarter of 2010 and surpassed every other exploitation category that the MMPC tracks, including generic HTML/scripting exploits, operating system exploits, and document exploits.

Exploits that use HTML and JavaScript steadily increased throughout the year and continue to represent a large portion of exploits. The most prevalent type of attack in this category involved malicious IFrames. The number of Adobe Acrobat and Adobe Reader exploits dropped by more than half after the first quarter, and remained near this reduced level throughout the remainder of the year.


In the first half of 2010, phishers showed signs of targeting online gaming sites with increasing frequency, although this push appeared to have dwindled as social networks came under increased attack. Impressions that targeted gaming sites reached a high of 16.7 percent of all impressions in June before dropping to a more typical 2.1 percent in December.

Phishing sites that target social networks routinely receive the highest number of impressions per active phishing site. The percentage of active phishing sites that targeted social networks increased during the final months of the year, but still only accounted for 4.2 percent of active sites in December, despite receiving 84.5 percent of impressions that month. Nevertheless, the number of active sites targeting gaming sites remained relatively high during the second half of the year, which suggests that more campaigns may be coming.

Successful strategies to avoid frequent password changes

Posted on 19 August 2014.  |  After a widespread, nonspecific data breach, the conventional wisdom is that people should change all their passwords. But, there’s a better way.
