Recently I wrote an article about the importance of using two-factor authentication (2FA), with a caveat that there is a serious flaw in the way most people use it. Today you'll learn about a gadget called the Titan Key that makes 2FA (and your online accounts) virtually hacker-proof. Read on...

Reddit, the maverick social network, suffered a security breach in June, 2018, its management has revealed. It was a mild disaster, as such things go. But it highlights a flawed method of online authentication that you are probably using on a regular basis. Here's what you need to know…

For the past few weeks, I've been writing a series on router security, and in this final installment I'll tell you what I think it the MOST important security feature that your router should have. “Self-updating” is the basement floor of my house of router standards. I can’t imagine Windows without self-updating, and keeping a router’s operating system patched is no less critical. Read on for my recommendations on secure, self-updating routers...

You may be aware that your router has a “guest network” feature, and you may think you know what it does. But a guest network is useful even when you do not have visiting relatives or friends. Let’s look at guest networks in detail and see how one can protect your home from cyber-intruders constantly...

As home network owners become more aware of security threats that target routers they are asking, “Does my security suite defend my router along with the other devices on my network?” Let’s look at some of the most popular security suites and see exactly how they protect routers, if they do so at all. Read on...

Avast and AVG are two of the most respected names in Internet security software. But many consumers don’t know that they became one company in October, 2016, when Avast bought AVG for $1.6 billion. Since then, the two software brands have remained distinct. But under the hood, they have grown more alike. There are still some differences in important features that may sway your choice. Let’s compare Avast Free Antivirus to AVG AntiVirus Free...

This article is part of a series on the subject of router security. In this article, we will examine one type of router vulnerability and learn how to protect your system from hackers and malware that seek to exploit this type of vulnerability. Our subject today is, “unnecessary open ports,” a very common vulnerability. Read on...

It was an awkward moment in 2006 when one of the most useful and popular networking features ever invented was discovered to also be very useful to hackers. Some vendors got busy on the problem, improving their product and making it more difficult for bad guys to exploit it. But hundreds more deliberately ignored the threat. Read on find out if you are exposed to the UPnP (Universal Plug-N-Play) vulnerability...

“Don’t put all your eggs in one basket,” they say. Yet most of us do exactly that with all of our expensive “smart” home electronics, and the consequences can be as calamitous as the old proverb implies. The latest cyber attacks are targeting home internet routers. Here's the first article in a series detailing what you need to know to defend yourself against router attacks...

The security suites that I have examined over the past few days all operate on the same basic principle: the blacklist. Malware is identified as such and gets put on a list of things to quarantine. The vast majority of antivirus and other types of security programs employ blacklisting. But this paradigm has some serious limitations. Here's what you need to know about the whitelisting approach…

We may forgive the Internet for being insecure; after all, it wasn’t designed to be secure. But locks certainly are, by definition. When you make something smarter it gets better, right? No, not always. Here's what you need to know about smart locks...

Oh, MalwareBytes, how I hope you make it! I admit up front that I admire this security suite purely for its aesthetics and attitude towards customers. But the question remains: Can the Premium "always-on" version stop malware effectively? Let's take a look at the free and paid versions of the MalwareBytes internet security product...

A deadly serious threat is on the loose: a virus called VPNFilter that infects business and consumer-grade routers to steal passwords and other sensitive data from any device on a network served by an infected router. Here's what you need to know now...

Unlike most internet security products, Norton does not have a free watered-down version of its security suite. But you do get 60 days to try Norton products before your credit/debit card is charged for the first time. So continuing my exploration of free versus paid anti-malware tools, I took the Deluxe version of Norton Internet Security for a test drive. Read on for my verdict...

Like most security software developers, Avira has evolved to include far more than detection and eradication of viruses (self-replicating destructive malware). That’s why I now prefer the term “security suite” over “antivirus” when discussing such products. In this article, I'll give you my advice on the wisdom of upgrading from a free to paid version of the Avira security software...

I have always been a fan of free software; all but a handful of the hundreds of programs I have recommended over the years have had a free version as well as a paid one. Every top-tier anti-malware suite offers full-spectrum protection in its free version. So why pay for any of it? Here's my take on the paid version of one popular Internet security product...

A new report that looks at the big picture pegs the worldwide haul from cybercrime at 1.5 trillion dollars.

Fly fishermen are always tying new flies, refining the tricks they play on trout and other piscean species. Likewise, phisher-men in the digital waters constantly try new ways to get you to bite on their hook, which is baited with malware. Recently, researchers at Kaspersky Lab reported a fancy new “fly” involving Facebook’s Messenger, the bigger, better messaging app that Facebook is pushing to replace that awful, tiny, temperamental chat box. Read on to see how Messenger has been used to deceive users into clicking links that lead to loss...

The FBI has issued an updated bulletin warning the public about the rising threat of “virtual kidnapping scams,” in which unseen bad guys call a victim and demand ransom for an allegedly kidnapped loved one. Here's what you need to know...

You may have heard of Spectre and Meltdown, two security vulnerabilities that exist in virtually every CPU ever made by the chip giants Intel, AMD, and ARM.

Over the past two decades, password rules have become more complicated and burdensome upon users. Users have coped with arbitrary, byzantine password rules by creating the most easily remembered passwords that comply with the rules, changing them when required in minor, predictable ways, and reusing compliant passwords on multiple online accounts. The results include lots of frustration and LESS security. Here's how to do it right...

Your Android smartphone is under attack from many directions, from pickpockets to malware to human error and suspicious spouses.

While everyone was preoccupied with the Wannacry ransomware epidemic that began in mid-May, a bigger threat was secretly spreading through tens of thousands of computers. It locks up files and demands a ransom, too, but that’s just a smoke screen designed to distract victims from what this sneaky malware is really up to. Here's what you need to know about DoublePulsar…

More than 70% of new malware released these days is of the ransomware variety. Why? Because it works! Ransomware takes all of a user’s data hostage, a terrifying moment for most of us.
