TOP VULNERABILITY THIS WEEK: Detailed research from the University of

Cambridge was released this week on weaknesses in the random number
scheme used as part of the process of securing chip-and-pin
transactions. The vulnerability allows for simple man-in-the-middle
attacks, likely impacts a large number of banks and device vendors, and
there are indications that the technique is already being used by
criminals in the wild.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Chip and PIN random number vulnerability
Description: Researchers at the University of Cambridge recently
discovered that random numbers which play a crucial role in chip-and-pin
card transactions throughout the world are actually predictable in many
cases, allowing for straightforward man-in-the-middle attacks against
virtually any electronic payment system in the world. The research began
after individuals who had been the victim of fraudulent transactions
against them brought the cases to the researchers’ attention, indicating
that criminals are already exploiting this vulnerability in the wild.

Title: Dorifel/Quervar/XDocCrypt causing major damage worldwide
Description: This malware of many names is the latest example of a
recent trend of more destructive payloads. Delivered via a variety of
mechanisms, including exploit kits and social engineering scams, Dorifel
searches out all of the Microsoft Word documents on an infected system
and then encrypts them, rendering them unusable for the average user.
Infections are widespread enough to have taken entire offices offline
during cleanup, particularly in the Netherlands. While initial media
reports about the malware have slowed, the Sourcefire VRT has
information indicating that this destructive piece of software is still
actively spreading in the wild.

Title: GoDaddy DNS outage temporarily kills millions of web sites worldwide
Description: Major hosting provider GoDaddy was suffered a major outage
on Monday, with their DNS services worldwide taken offline. As they
provide DNS services for millions of web sites worldwide, this resulted
in a major Internet outage for thousands upon thousands of innocent
parties. Initial reports claimed that it was a hack, although GoDaddy
later claimed it was due to internal network issues. Regardless,
GoDaddy’s lack of geographical and AS-based redundancy for its DNS
service highlights just how vulnerable many sites are to attacks if they
lack proper disaster recovery and redundancy plans.
