We recently announced the release of AsyncOS 9.5 for Cisco Email Security that included the integration of AMP Threat Grid. Now if Threat Grid could talk it would sound a lot like Ron Burgundy and say “I’m not sure if you know this, but I’m kind of a big deal.” Email is consistently one of the top two threat vectors for malware because so many people out there still open an attachment that looks harmless from someone they don’t know. We all want to think we won a cruise, but that’s not how it works. It’s how malware establishes a foothold on your system. AMP Threat Grid is there to make sure this doesn’t happen.
Cisco acquired Threat Grid to not only bolster its suite of advanced threat solutions, but to also integrate the technology into its advanced malware protection (AMP) products. AMP Threat Grid goes far beyond traditional sandboxing, providing a host of analytical engines to evaluate potential malware. From static and dynamic analysis to various post-processing techniques, AMP Threat Grid evaluates malware to provide the most comprehensive report for even the most junior security analysts. This video provides a more comprehensive overview. Those familiar with Cisco’s Email Security know we already had a sandbox built in and may ask ‘Why change?’ and that’s exactly the question you want to ask. There are really three key reasons: Read More »

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:
