I have known Dave Piscitello for several decades; he and I served together with a collection of some of the original inventors of the Internet and he has worked at ICANN for many years. So it is interesting that he and I are both looking at spam these days with a careful eye.
He recently posted a column saying “It sounds trivial but spam is one of the most important threats to manage these days.” He calls spam the security threat you easily forget, and I would agree with him. Why? Because spam brings all sorts of pain with it, mostly in the form of phishing attacks and other network compromises. Think of it as the gateway drug for criminals to infect your company with malware. A report last December from PhishMe found that 91% of cyberattacks start with a phish. The FBI says these scams have resulted in $5.3 billion in financial losses since October 2013.
We tend to forget about spam these days because Google and Microsoft have done a decent job hiding spam from immediate view of our inboxes. And while that is generally a good thing, all it takes is a single email that you mistakenly click on and you have brought an attack inside your organization. It is easy to see why we make these mistakes: the phishers spend a lot of time trying to fool us, by using the same fonts and page layout designs to mimic the real sites (such as your bank), so that you will login to their page and provide your password to them.
Phishing has gotten more sophisticated, just like other malware attacks. There are now whaling attacks that look like messages coming from the CFO or HR managers, trying to convince you to move money. Or spear phishing where a criminal is targeting someone or some specific corporation to trick the recipient into acting on the message. Attackers try to harvest a user’s credentials and use them for further exploits, attach phony SSL certificates to their domains to make them seem more legitimate, use smishing-based social engineering methods to compromise your cell phone, and create phony domains that are typographically similar to a real business. And there are automated phishing construction kits that can be used by anyone with a minimal knowledge to create a brand new exploit. All of these methods show that phishing is certainly on the rise, and becoming more of an issue for everyone.
Yes, organizations can try to prevent phishing attacks through a series of defenses, including filtering their email, training their users to spot bogus messages, using more updated browsers that have better detection mechanisms and other tools. But these aren’t as effective as they could be if users had more information about each message that they read while they are going through their inboxes.
There is a new product that does exactly that, called Inky Phish Fence. They asked me to evaluate it and write about it. I think it is worth your time. It displays warning messages as you scroll through your emails, as shown here.
There are both free and paid versions of Phish Fence. The free versions work with Outlook.com, Hotmail and Gmail accounts and have add-ins available both from the Google Chrome Store and the Microsoft Appsource Store. These versions require the user to launch the add-in proactively to analyze each message, by clicking on the Inky icon above the active message area. Once they do, Phish Fence instantly analyzes the email and displays the results in a pane within the message. The majority of the analysis happens directly in Outlook or Gmail so Inky’s servers don’t need to see the raw email, which preserves the user’s privacy.
The paid versions analyze every incoming mail automatically via a server process. Inky Phish Fence can be configured to quarantine malicious mail and put warnings directly in the bodies of suspicious mail. This means users don’t have to take any action to get the warnings. In this configuration, Outlook users can get some additional info by using the add-in, but all the essential information is just indicated inline with each email message.
I produced a short video screencast that shows the differences in the two versions and how Phish Fence works. And you can download a white paper that I wrote for Inky about the history and dangers of phishing and where their solution fits in. Check out Phish Fence and see if helps you become more vigilant about your emails.
The days of simple anti-malware protection are mostly over. Scanning and screening for malware has become a very complex process, and most traditional anti-malware tools only find a small fraction of potentially harmful infections. This is because malware has become sneakier and more defensive and complex.
In this post for CSO Online sponsored byPC Pitstop, I dive into some of the ways that malware can hide from detection, including polymorphic methods, avoiding dropping files on a target machine, detecting VMs and sandboxes or using various scripting techniques. I also make the case for using application whitelisting (which is where PC Pitstop comes into play), something more prevention vendors are paying more attention to as it gets harder to detect the sneakier types of malware.
As more banking customers make use of mobile devices and apps, the opportunities for fraud increases. Mobile apps are also harder to secure than desktop apps because they are often written without any built-in security measures. Plus, most users are used to just downloading an app from the major app stores without checking to see if they are downloading legitimate versions.
Besides security, mobile apps have a second challenge: to be as usable as possible. Part of the issue is that the usability bar is continuously being raised, as consumers expect more from their banking apps.
In this white paper for VASCO, I show a different path. Mobile banking apps can be successful at satisfying the twin goals of usability and security. Usability doesn’t have to come at the expense of a more secure app, and security doesn’t have to come at making an app more complex to use. Criminals and other attackers can be neutralized with the right choices that are both usable and secure.
Today most of us go about implementing security from the outside in. The common practice to define and then defend a perimeter isn’t viable any longer. With the added complexities of more mobile endpoints, agile development and more sophisticated malware, better protective methods are needed.
In this whitepaper for Vasco (the link to my paper is on the right-hand menu), I describe a method that is gaining traction by defending the actual apps themselves using runtime self-protection. RASP, as it is called, comes from a Gartner 2012 report, but is catching on with several vendors, including Arxan Technologies, HPE App Defender, Immun.io, Lookout App Security/Bluebox, Prevoty, Vasco Digipass for Apps, Veracode and Waratek.
RASP can be a solid defense and a way to isolate and neutralize a potential threat, so you can operate your business safely in these uncertain environments.
The National Institute of Standards recently issued a ruling on digital authentication that states SMS messaging as a second authentication factor should now be considered insecure. While sending an SMS for OTP is still better than having no additional authentication factors, the NIST ruling suggests that organizations wanting to raise the bar on their security standards consider more secure authentication methods.

The web browser has become the defacto universal user applications interface. It is the mechanism of choice for accessing modern software and services. But because of this ubiquity, it puts a burden on browsers to handle security more carefully.
Because more malware enters via the browser than any other place across the typical network, enterprises are looking for alternatives to the standard browsers. In this white paper that I wrote for Authentic8, makers of the Silo browser (their console is shown here), I talk about some of the issues involved and benefits of using virtual browsers. These tools offer some kind of sandboxing protection to keep malware and infections from spreading across the endpoint computer. This means any web content can’t easily reach the actual endpoint device that is being used to surf the web, so even if it is infected it can be more readily contained.
The new “my way” work style and the demand for on-the-go access to any service from any device and virtually any location requires that you bring your best encryption game with you when you’re on the move. This is especially true for the group of people often labeled Gen Y, or 20-somethings. Why? Because they are so digitally native and so used living their lives with instant access to their money, their friends, really anything that they do. As they are so steeped in technology, they tend to forget that there are lots of folks online who want to steal their identities, empty their bank accounts, and cause other havoc with their digital lives. But Gen Y is also more likely to use mobile banking than their elders, and more likely to go elsewhere if banks do not offer the mobile services they desire.
For a white paper for Vasco, I wrote about the challenges around providing better and more native authentication technologies for Gen Y and indeed, all users.
The market for hyper-converged systems is quickly evolving. Traditional storage infrastructure vendors remain the largest installed base, but software-defined and hyper-converged storage providers represent the fastest growing market segment, with some of the latter vendors rapidly increasing their market share.
This get-up-to-speed guide posted here will help you navigate the hyper-converged infrastructure options.
Virtual desktop infrastructure, better known as VDI, is undergoing a new life. A few years ago, it was plagued by lackluster user experiences and cost overruns. Now, thanks to an injection of new technology and better implementations, there’s a lot to like. Faster, cheaper technology has made it an interesting option for companies seeking a way to support flexible, work-from-anywhere environments.
How does this transformation happen? This get-up-to-speed guide posted on ITworld explores how VDI can help organizations navigate shifts in business, and user needs.
Making a case for moving legacy apps to the cloud is becoming easier, with the biggest driver being the ability to shift costs from capital to operating expenses, which can save money. Also, renting capacity rather than owning servers and network infrastructure allows more flexibility in how computing resources are provisioned, enabling workloads to be matched to demand. Quick provisioning is key: New servers can be brought up in the cloud in just minutes, not only making it easier to improve availability but also enabling more flexible disaster recovery mechanisms.
This get-up-to-speed guide explores the key approaches to migrating legacy apps to the cloud, and the value each can bring to your business. You can download my guide here.
