By Jolene Tam Overwhelmed by the sheer volume of security alerts and potential threats hitting your SOC? Security risks have never been greater, with networks expanding into the cloud, the explosion of mobile and IoT devices, and increasingly sophisticated threats. On top of that, disparate security tools make it tougher to find and remediate threats, especially when you’re under attack and time matters most.
So how can you stay ahead of threats? Enter Cisco Threat Response, a tool that was created to help SOC analysts simplify and speed threat detection, investigation, and remediation from a single interface.
This week at Cisco Live, we’re excited to share continued innovations from Threat Response designed to make your life even easier.
1. Introducing our integration with Cisco Firepower NGFW
You may know that Threat Response is already integrated across multiple Cisco Security products – AMP for Endpoints, Threat Grid, Umbrella, and Email Security. In the coming weeks, you will be able to analyze and triage high priority IPS alerts in Threat Response and enrich these IPS events alongside data from other integrated products. This means streamlined threat investigations with a fuller picture of the impact across your network, all from a single console.
Join us at Cisco Live to get a preview of this exciting integration. You can see a live NGFW with Threat Response integrated demo at the Cisco Security booth in the World of Solutions. In the meantime, check out this new episode of ThreatWise TV that showcases how Firepower events are integrated into Threat Response.
2. Learn how to enhance your existing SIEM and SOAR tools with open APIs
Threat Response isn’t trying to replace the SIEM or SOAR you’ve already got; rather you can leverage our open APIs for 3rd-party integrations to complement your existing security stack. Script up your own integrations to automate data enrichment and response actions across multiple security products, all in a single interface for a seamless workflow.
At Cisco Live, get your learn on and get hands-on in the DevNet Zone:
DEVNET-2505– Automate your threat hunting workflow with Cisco Threat Response APIs – Presented by Christopher Van Der Made.
DEVWKS-2639– Security Research and Response Workflows with APIs – Workshop with Neil Patel.
3. Use our browser plug-ins to access threat intel and kick off investigations now
Still haven’t leveraged our APIs or you’re using non-Cisco security products? Don’t worry, you can still use Cisco Threat Response thanks to our browser plug-ins for Chrome and Firefox. In seconds, you’ll be able to pull threat intelligence to get verdicts on observables and start investigations.
You can see the Threat Response browser plug-in in action in demos and breakout sessions at Cisco Live. We’ll show you how you can pull threat data from sources like Talos and take actions without native integrations.

By Talos Group It has been 10 years since the discovery of Skimer, first malware specifically designed to attack automated teller machines (ATMs). At the time, the learning curve for understanding its functionality was rather steep and analysis required specific knowledge of a manufacturer’s ATM API functions and parameters, which were not publicly documented.
Before the discovery of Skimer, anti-malware researchers‘ considered ATMs secure machines containing proprietary hardware, running non-standard operating systems, and implementing a number of advanced protection techniques designed to prevent attacks using malicious code. Researchers eventually discovered that the most popular ATM manufacturers use a standard Windows operating system and add on some auxiliary devices, such as a safe and card reader.
Over time, actors behind some of the newer ATM malware families such as GreenDispenser and Tyupkin realized that there is a generic Windows extension for Financial Services API (CEN/XFS) that can be used to make malware that runs independent of the underlying hardware platform, as long as the ATM manufacturer supports the framework. This malware can trick the machines into dispensing cash, regardless of whether the attacker has a legitimate bank card.
Over time, ATM malware has evolved to include a number of different families and different actors behind them, ranging from criminal groups to actors affiliated with nation states. The significance of ATM malware stems from the fact that it can bring significant financial benefits to attackers and as a consequence cause a significant damage to targeted banks, financial institutions and end users.
Now that this type of malware has been around for more than 10 years, we wanted to round up the specific families we’ve seen during that time and attempt to find out if the different families share any code.

By Ben Nahorney Let’s be honest: administering email is a pain. Routing issues, disk quotas, bouncebacks, the times when users can send but not receive emails, receive but not send, or they flat out cannot send or receive—the list goes on.
It’s no wonder that email-hosting services like Office 365 have become so popular. Such cloud-based email services remove a lot of the headaches caused by email configuration. They even include basic security features, meant to keep users safe from the latest threats.
They also provide options to simplify the user experience. Users can go directly to an Office 365 web page, enter their company credentials and log right into their email accounts from anywhere they like.
Take all this into account, add the reduction in costs that cloud email solutions often bring, and it sounds like the perfect solution. As a result, the use of services like Office 365 has skyrocketed.
Attackers have taken notice
Of course, its popularity has led to malicious attacks. Attackers are crafting and launching phishing campaigns targeting Office 365 users. The attackers attempt to steal a user’s login credentials with the goal of taking over the accounts. If successful, attackers can often log into the compromised accounts, and perform a wide variety of malicious activity:
Spread malware, spam, and phishing emails from within the internal network.
Carry out tailored attacks such as spear phishing and Business Email Compromise.
Target partners and customers.
At first glance, this may not seem very different than external email-based attacks. However, there is one critical difference: The malicious emails sent are now coming from legitimate accounts. For the recipient, it’s often even someone that they know, eliciting trust in a way that would not necessarily be afforded to an unknown source. To make things more complicated, attackers often leverage “conversation hijacking,” where they deliver their payload by replying to an email that’s already located in the compromised inbox.
Figure 1 – An example Office 365 phishing email.
Reconnaissance attacks
However, there’s so much more that an attacker can do besides sending emails. Once an attacker has access to a legitimate mailbox, they can also do the following:
Obtain global company email address lists.
Scan mailbox for other credentials, personal information, or company information.
Attempt to gain further access to company resources.
These activities can go unnoticed, simply because the attacker is gathering information while logged in using authorized credentials. This gives the attacker time for reconnaissance: a chance to observe and plan additional attacks. Nor will this type of attack set off a security alert in the same way something like a brute-force attack against a webmail client will, where the attacker guesses password after password until they get in or are detected.
The attack chain
The methods used by attackers to gain access to an Office 365 account are fairly straightforward. The phishing campaigns usually take the form of an email from Microsoft. The email contains a request to log in, claiming the user needs to reset their password, hasn’t logged in recently, or that there’s a problem with the account that needs their attention. A URL is included, enticing the reader to click to remedy the issue.
The chain of events usually plays out like this:
Attacker sends a phishing email that appears to come from Microsoft or another trusted source.
User clicks on link in the email, which brings them to a page mimicking the Office 365 login page.
User enters login credentials, which are scooped up by the attackers.
The fake page does nothing, says that the login is incorrect, or redirects the user to the real Office 365 login page.
Given this series of events, the user would be none-the-wiser that their credentials had been stolen.
Figure 2 – Office 365 login vs. phishing login. Can you spot the difference?
The frequency of attacks
How successful are these attacks? While it’s unlikely anyone but the attackers would have data on the number of stolen credentials, or overall success rate, we can draw a few conclusions by looking at the phishing emails.
Agari Data Inc. is one company that monitors a variety of data points surrounding phishing campaigns. In fact, in their quarterly Email Fraud and Identity Deception Trends report, they often look at brand impersonation trends and provided some fresh numbers for us.
Over the last few quarters, there has been a steady increase in the number of phishing emails impersonating Microsoft. While Microsoft has long been the most commonly impersonated brand, it now accounts for more than half of all brand impersonations seen in the last quarter.
Figure 3 – Brand Impersonation Phishing Emails masquerading as “Microsoft”
Cloud email security efficacy
To its credit, Microsoft has baked a number of security technologies into its Office 365 offerings. However, given how these types of phishing attacks take place off their network, there is very little that can be done from within the cloud to protect against it. If an attacker gains valid credentials and uses them, how can you tell the difference based on a login attempt?
Fortunately, there are several steps you can take to further protect your email:
Use multi-factor authentication. If a login attempt requires a secondary authorization before someone is allowed access to an inbox, this will stop many attackers, even with phished credentials.
Deploy advanced anti-phishing technologies. Some machine-learning technologies can use local identity and relationship modeling alongside behavioral analytics to spot deception-based threats.
Run regular phishing exercises. Regular, mandated phishing exercises across the entire organization will help to train employees to recognize phishing emails, so that they don’t click on malicious URLs, or enter their credentials into malicious websites. For instance, Duo offers a free phishing simulation tool, called Duo Insight.
On the horizon
Cloud email services like Office 365 aren’t going anywhere. Given the many advantages that they present, there’s no reason they should. The fact is, given the current threat landscape, it’s often necessary to leverage additional security.
Based on a recent study conducted by ESG on behalf of Cisco, more than 80 percent of respondents reported that their organization is using SaaS email services. However, 43 percent of respondents still found that, after the move, they required secondary security technologies in order to shore up their email defenses.
At the end of the day, there are still valid needs for IT teams to set policies, gain visibility and control, utilize sandboxes, and leverage external blocking capabilities. Cloud email offers a lot of advantages, but to fully deliver on its promise, there is still a role for IT to ensure it is as secure as it can be.
