2013 Threat Report: More Than Scary Stats and Chilling Charts

Posted: 13 Feb 2013 08:30 | Carl Leonard


The 2013 Threat Report from the Websense® Security Labs™ is now available.

 

The report details mobile, social, email and web-based threats, and while it is full of ominous data points, it is a very interesting read. The report is designed to help security professionals keep current with threat trends and improve the effectiveness of existing security solutions. It can also be used to identify and prioritize security gaps that may require new approaches and more innovative strategies.

 

Creating the report began with the ThreatSeeker® Network, composed of big data clusters used by the WSL to collect and manage up to 5 billion inputs each day from 900 million global endpoints. Malware samples, mobile applications, email content, web links and other information were then passed through deep analysis processes including our Advanced Classification Engine (ACE), which applied over 10,000 different analytics.

When Less is More: The Growing Impact of Low-Volume Email Attacks

Posted: 05 Oct 2012 01:00 | Ran Mosessco


Here at Websense® Security Labs, we often blog about big malicious campaigns and how our products protect our customers from them. But what about smaller campaigns that are no less dangerous? 

 

Broad campaigns often spoof notifications from well-known businesses, establishments, organizations, and agencies, and are very widespread these days. However, smaller volume campaigns sometimes can be as (or even more) dangerous by bypassing the victim's defenses.

 

Last week, the Websense ThreatSeeker® Network intercepted one such campaign. This small-volume, malicious campaign targeted businesses with legitimate-looking email that refer to items like purchase orders, quotes, and supply information. All of these email had attachments that install variants of the popular Zeus malware on the victim's computer.

 

Websense Cloud Email Security quarantined these email as containing a potential virus before most of the malicious attachments were detected by antivirus (AV) engines. ACE, our Advanced Classification Engine, provides the extra layers of protection that help Websense Cloud Email Security protect customers against a wide array of threats.
