Malware Trends Affect Key Industries
In its first Threat
Landscape Review software security giant Palo
Alto Networks
takes a high-level view of how malware is delivered to networks
across major
industries around the world. The data used for this report was
derived from WildFire™. The firewall application automatically
identifies threats from malware over a wide array of applications by
executing them in a virtual environment, observing their behavior.
This data was collected from live systems in networks belonging to
2,363 different companies operating in 82 different countries.
There are currently
over 4,000 organizations using WildFire to defend their networks. The
following are key findings from this report:
- Globally, the platform detected malware delivered in over 50
distinct applications. 87% of this malware was delivered over SMTP,
11.8% through Web-Browsing (HTTP) and 1.2% in the remaining
applications.
- While all verticals saw SMTP and HTTP as the primary channels for malware delivery, they varied greatly in the percentage for each. Retail and Wholesale organizations received almost 28% of malware over the web channel while Hospitality organizations received less than 2% through the same channel.
- Over 90% of unique malware samples were delivered in just 1 or 2 sessions, while a much smaller proportion was delivered in over 10,000 attacks.
- One malware family, known as Kuluoz or Asprox, was
responsible for approximately 80% of all attack sessions recorded in
the month of October. This malware sends copies of itself over
e-mail quickly and to users all around the world and then attempts
to download additional malware, impacting 1,933 different
organizations.
