In the last five years, we’ve all become far too familiar with it – hackers spoofing a company’s domain and therefore tarnishing the brand, bad actors attempting to infect our computers with malware, and criminals sending millions of spam messages. As if this isn’t enough, now there is a whole group of people working to outsmart companies AND their customers by using cousin domains to fool...

With the high volume of email activity the holiday season brings, we’ve been getting a lot of questions about holiday email scams – what to look for and how to avoid them. So in the spirit of giving…some good advice…our Field CTO John Wilson has published a blog on LinkedIn with suggestions that can help people better protect themselves from online criminals, and help businesses ensure they aren’t...

Snowflakes and Early Automation Efforts At Agari, as part of our mission to solve phishing, we deal with data at scale. We’ve chosen AWS to help us move quickly, making sure our infrastructure is as agile as we are. Unfortunately, in the beginning, we treated AWS instances much the same way as physical servers: each configuration was lovingly hand-crafted, packages were installed at the command...

Steve Katz - “Phishing and social engineering is still a global threat to every business around today.” Last year, phishing attacks cost organizations $4.5 billion in losses, but as we all know the loss is not only monetary. These attacks exploit the trust we as customers have in the brands we use. Recently Agari sat down with the Financial Services industry's first CISO, previous CSO of Citi...

At Agari, we are vocal about the steps organizations can take to protect their brands and customers from the impact of phishing attacks. But what exactly are the hard numbers behind our mission? Let’s look at some phishing statistics showing a clear need for change when it comes to mitigating the phishing problem. A rising threat Verizon research has found that phishing is now the second most...

In the second in our series of blogs on the Fundamentals of Phishing we will explore how to identify fraudulent emails. Not that long ago, phishing attempts were quite primitive and often full of errors, and it was easier for consumers to identify when something was amiss. In addition, consumers weren’t accessing their inboxes from multiple devices and mobiles, nor did they expect to receive...

I first heard about the Ashley Madison breach on July 15, 2015 in a post by Brian Krebs . I immediately wondered what the fallout of such a breach would be. Would Ashley Madison's new tagline be "1 million divorces and counting!" Would the perpetrators try to profit from the stolen data, perhaps through blackmail? I never imagined I'd soon have the chance to explore the dataset myself, after...

Workflow Schedulers Workflow schedulers are systems that are responsibile for the periodic execution of workflows in a reliable and scalable manner. Workflow schedulers are pervasive - for instance, any company that has a data warehouse, a specialized database typically used for reporting, uses a workflow scheduler to coordinate nightly data loads into the data warehouse. Of more interest to...

With the X-Files soon making a return to the small screen (!!!), I have been thinking a lot lately about the concept of trust. Specifically as it relates to security, and especially the concept of "Zero-Trust". Many security front-runners have begun enacting a new security architecture called Zero-Trust Networking and it really took off when Google decided to implement it . The underlying...

Data science applications provide much of the power behind Agari’s e-mail security products. The e-mail landscape is vast and dynamic, and we require the ability to regularly analyze incoming data. Models including forwarder classification , malicious campaign identification, domain reputation, and inbound sender modeling are created on hourly to daily cadences. We therefore need a fast and cost...

Motivation Among the challenges that our engineering team faces is the ability to classify an email-sending entity as a forwarder. At Agari , we are primarily interested in the authentication of emails from originating senders. Forwarders are defined as entities which forward messages from originating senders as well as from other forwarders. Examples include servers in educational institutions...

Agari's mission to solve email phishing often presents unique technical challenges. Our data ingestion process involves coping with large-scale inbound SMTP traffic. We've chosen Postfix as our MTA of choice. The traditional way to scale SMTP is simply to maintain MX records for multiple ingestion paths. This works but can be very limiting. Agari's Amazon Web Services-hosted infrastructure...

Data-rich companies ( e.g. LinkedIn, Facebook, Google, and Twitter ) have historically built custom data pipelines over bare metal in custom-designed data centers. In order to meet strict requirements on data security, fault-tolerance, cost control, job scalability, and uptime, they need to closely manage their core technology. Like serving systems ( e.g. web application servers and OLTP databases...

Over a year ago, Target publicly acknowledged the now infamous data breach. For many weeks afterwards, news of the Target breach dominated the headlines. Cyber security was no longer just a topic for security professionals; the topic had gone mainstream. Sadly, 2013 was quickly eclipsed by 2014 in terms of data breaches. In a report released on December 9 th , 2014, the Identity Theft Resource...

Someone again hands you a business card, this time with a PayPal logo on it. You ask them how they like working at PayPal, and the person says, “I don’t work...
