Each day more than 100 billion corporate email messages are exchanged1. Who doesn’t need to do a little housekeeping and eliminate unwanted emails? But you need to think twice before you click on “unsubscribe.”
As you likely read in the 2015 Cisco Annual Security Report, attackers are using applications users inherently trust or view as benign, like web browser add-ons, to distribute malware. One of the latest phishing techniques is graymail – directing the “unsubscribe” link at the bottom of a seemingly innocuous marketing email to a malware infested website. Many of us click on these links without a second thought. But instead of ridding ourselves of unwanted emails, we’re actually opening ourselves up to an attack.
This is just one example of how attackers continue to innovate, and Cisco does as well. Our new AsyncOS release for Cisco Email Security Appliance (Cisco ESA) demonstrates how Cisco empowers you with a threat-centric approach to security and more comprehensive management control.

If you read the recently released Cisco Annual Security Report, you will have learned how spammers have adopted a “Snowshoe” strategy, using a large number of IP addresses with a low message volume per IP address, to send spam, preventing some spam systems from sinking the spam. This yielded a 250 percent increase in spam from January 2014 to November 2014. Or, perhaps the fact that malicious actors are using malvertising (malicious advertising) from web browser add-ons as a medium for distributing malware and unwanted applications caught your eye in the report. In order to protect against these types of emerging threats, Cisco showcases its continued thought leadership in email security to offer even greater protection and control across the attack continuum, while also providing additional flexibility for centralized management.

My personal email has 4 characteristics that drive me crazy:
- I get way too much email
- Most of my emails are a waste of time
- Emails carry the risk of, very rarely, nasty virus payloads (or link you to sites that have worse)
- Despite all this, I can’t live without email Read More »

In recent weeks, the volume of malicious email carrying attachments has increased substantially. To entice recipients into opening those attachments, attackers are employing pitches across a wide range of subjects. In doing so, they are defeating the often doled out advice to not open attachments in email received unexpectedly.
One of the more striking examples of this is malicious email exploiting bad economic conditions, job loss, and potential loss of home. The combined legal and job categories comprised 33% of malicious email attachments over the past two weeks, with pitches ranging from bogus employment opportunities to court summons for evictions due to overdue payments.
Other legal-oriented email includes warnings of illegal use of software, copyright infringement, and criminal complaints for alleged non-payment of accounts.
Assuming you were in dire financial straits, it’s not difficult to imagine you would react to an eviction notice such as the following:

Please visit Cisco’s TechEd web site to learn more about what we have going on at the show and visit www.cisco.com/go/microsoft to learn more about Cisco’s Microsoft capabilities.
I first attended Microsoft TechEd in 1996 in Los Angeles. What a learning experience it was.
This year, I’ll be there staffing the Cisco booth (#1701) speaking about the Cisco Unified Computing System.
- Do you run SQL, Exchange, SharePoint or other Microsoft applications?
- Want to learn about the x86 server technologies and solutions that have propelled Cisco to the #2 blade server vendor in the Americas and #3 worldwide1 in only 3 years?
- Would you like to see how you can have common set of management tools for your rack and blade servers that provide the missing hardware insight layer, with visibility from the chassis and rack all the way through to the virtual machine layer?
- Are you interested in a turn-key solution for your private cloud (FlexPod & VSPEX)?
If you answered “yes” to any of these questions, stop by and speak with the UCS server team.
Cisco will also be demonstrating:
Both the Nexus 1000V and FlexPod are finalist for the Best of TechEd 2013. We are very hopeful this will be our third year in a row to win a Best of TechEd award.
