Amid a troubling rise in zero-day phishing attacks, recent research suggests that some companies may be making an ill-advised shift away from blocking advanced email threats to responding to them post-delivery. If true, the capitulation couldn't come at a worse time. Since January, cybercriminals taking advantage of the COVID-19 outbreak have been targeting businesses and individuals with an...

Since the beginning of February, we have seen more than a 3,000% increase in Coronavirus-themed phishing attacks targeting our customers. The spike in attacks is as logical as it is repugnant.

Sometimes referred...

A growing body of evidence suggests employees throughout the healthcare sector may be uniquely vulnerable to phishing attacks. If finding itself a growing target for cybercriminals weren’t bad enough, the industry is also seeing associated lawsuits piling up. Montana-based Kalispell Regional Healthcare was recently hit with a suit after it disclosed that multiple employees had fallen victim to...

Editor's Note: This post originally appeared on the Microsoft Security blog and has been republished here. You already know that email is the number one attack vector for cybercriminals.

Scammers know that impersonating a trusted government agency is an extremely effective way to trick or scare victims into handing over money, personal data, or sensitive information. In many cases, it’s all too easy for cybercriminals to use the agency’s own domains to send authentic-looking phishing emails to constituents and contractors. That’s why the Department of Homeland Security announced...

This post originally appeared on the Armadillo Blog and has been lightly edited for clarity. Most organisations have been successful in blocking malicious emails targeted at their employees, at least to some extent. Various on-premise and cloud providers exist to take care of anti-spam, anti-virus, reputation scores, and advanced features such as sandboxing of executables. As a service provider...

Over the past 6 months, 100% of Agari customer brands and more than 80% of their domains have been the target of consumer phishing or B2B phishing attacks impersonating their brand to commit fraud. While the cost of phishing attacks isn't always visible, there are very real costs to businesses in the form of email deliverability, brand value and fraud costs. The root cause of this problem is that...

According to a public service announcement issued by the FBI, college students across the United States continue to be targeted in a common email phishing scam that lures students in with the promise of employment. It works like this: email Scammers advertise phony job opportunities on college employment websites or students receive emails on their student accounts recruiting them for fictitious...

One of the things that often stumps even the most security conscious companies is knowing all the third-party email service providers they are working with. It is extremely difficult, if not impossible for these organizations to protect their customers from phishing attacks if they don’t even know who is sending legitimate email on their behalf. And this gets even more challenging when you...

With the surge of phishing and other advanced email attacks, you can’t be too careful when it comes to your inbound email messages. Beyond viewing the basic information provided, you should make it a habit of viewing and understanding your emails' full headers.

Ask any security professional what the number one pain point is within their organization, and chances are they’ll say ‘user behavior’…with ‘malware’ coming in as a very close second. And while these issues are very different on the surface, they do have one thing in common: both are often the cause of high-profile data breaches, largely in part to the increased use of spear phishing email...

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...

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...

When you begin to work with DMARC, you realize just how important identifier alignment is. Identifier alignment forces the domains authenticated by SPF and DKIM to have a relationship to the "header From" domain. Header From Domain and the MailFrom domain are different? Yes, they are! Hearing these terms can confuse people. They sound like the same thing, but in reality they are not. The...

This is the second in a new ongoing series for us that gives you the tips and tricks you need for successful DMARC deployment . Read the previous tip here . DomainKeys Identified Mail (DKIM) is the successor to Yahoo DomainKeys. Both share similarities, however DKIM has the additional aspects of Cisco's Identified Internet Mail standard (IIM). The enhancements to this standard gives more security...

This is the start of a new ongoing series for us that gives you the tips and tricks you need for successful DMARC deployment. What does "PermError SPF Permanent Error: Too many DNS lookups" mean? There are several safeguards put in place with SPF . One of these is a limitation of DNS lookups to help ensure that you do not have timeout issues. SPF will evaluate only 10 DNS mechanism lookups in an...

One of the great things about a conference like BlackHat is that it gives people like me the opportunity to take a step back, get out of the specific back alleyways of cybersecurity that we usually inhabit, and take a broader, more holistic look at attack and defense. One concept that's been talked about for a while is the Cyber Kill Chain. It takes a military-theoretical approach to network asset...
