The Internet of Everything and digital privacy: what you need to know
If you don’t already own Internet of Things IoT devices, you likely will soon. IoT-enabled devices are physical gadgets with built-in Internet connectivity that allow data transmission; often this happens in the background with no indication to the user that anything is happening. The IoT is more...
Far Cry 5 download offers: embrace the power of “no”
The recently released Far Cry 5 is a video game where you reclaim Montana from a cult obsessed with the "power of yes" by hitting members over the head with a shovel. It's also one of the biggest sellers for publisher Ubisoft to date, and it stands to reason that many people would like to grab a...
New Crossrider variant installs configuration profiles on Macs
A new variant of the Crossrider adware has been spotted that is infecting Macs in a unique way. For the most part, this variant is still quite ordinary, doing some of the same old things that we've been seeing for years in Mac adware. However, the use of a configuration profile introduces a uniqu...
Securing financial data of the future: behavioral biometrics explained
Some of us would be pretty excited about a brave, new passwordless world. Gone would be the days of having to write down 27 passwords and post them beside monitor screens. Or having to yell them out loud to a colleague on the other side of the room. For banks and other financial institutions, a...
A week in security (April 16 – April 22)

Perspectives on Russian hacking
Russia is an endlessly fascinating subject both in and around infosec. Recent years have shifted attention away from pure malware capabilities, to psyops, social engineering, and an endless slew of mind games designed to destabilize and keep nations ever-so-slightly off balance. Security firms in...
PBot: a Python-based adware
Recently, we came across a Python-based sample dropped by an exploit kit. Although it arrives under the disguise of a MinerBlocker, it has nothing in common with miners. In fact, it seems to be PBot/PythonBot: a Python-based adware. Apart from a couple of posts on forums in Russian language and...
Magnitude exploit kit switches to GandCrab ransomware
The GandCrab ransomware is reaching far and wide via malspam, social engineering schemes, and exploit kit campaigns. On April 16, we discovered that Magnitude EK, which had been loyal to its own Magniber ransomware, was now being leveraged to push out GandCrab, too. While Magnitude EK remains...
5 cybersecurity questions retailers must ask to protect their businesses
The Target breach in 2013 may not be the biggest retail breach in history, but for many retailers, it was their watershed moment. Point-of-sale PoS terminals were compromised for more than two weeks. 40 million card details and 70 million records of personal information swiped—part of which was...
Myspace vs. Facebook: the good old days?
Many people have fond memories of ye olde Myspace dotte comme, and those rose-splashed spectacles seem to have grown ever larger in light of the recent Facebook happenings.

‘FakeUpdates’ campaign leverages multiple website platforms
A malware campaign which seems to have started at least since December 2017 has been gaining steam by enrolling a growing number of legitimate but compromised websites.

Maybe you shouldn’t use LinkedIn
UPDATE: 4/6/2018 LinkedIn reached out for comment on the article, and we'd like to clarify our position based on their concerns. They wrote: Members control their connections, who can see them including keeping them private if they wish and only first degree connections can get access to your...
LockCrypt ransomware: weakness in code can lead to recovery
At the start of the year, it seemed that 2018 was going to be all about cryptominers. They so overwhelmingly dominated the landscape that it looked like no other threat had a chance. However, ransomware is not giving up the field so fast. There have been new variants popping up every couple of...

TLS 1.3 is nearly here
TLS stands for "Transport Layer Security" and it's rather important. Why's that? Oh, I'm glad you asked. Here's me, yelling my password across the office to you: "PASSWORD!!!" You heard me loud and clear, right? But so did basically anyone else nearby. Now let's work in a little TLS love and...
The data breach epidemic: no info is safe
By now it’s obvious that data security technology and protocols haven’t kept pace with the needs of consumers.

Exploit kits: Winter 2018 review
In the past, we used to do a blog series on exploit kits where we would periodically check in on the main players in the market. In March 2017, we wrote the Winter 2017 review, before exploit kit activity dropped down to a whisper. We've since discontinued our blog series, for lack of development...

What Facebook’s Cambridge Analytica problem means for your data
As you may already know, there's been a security meltdown at Facebook, thanks to a company called Cambridge Analytica and Donald Trump.

Malicious cryptomining and the blacklist conundrum
When Coinhive first came out in September of 2017, it was fairly easy to identify websites using browser miners by looking for a few lines referencing the Coinhive API within the HTML source code. Because this was a new phenomenon, even bad actors didn't have to hide their intentions, and...
“Celebrating Stephen Hawking” with a 419 scam
The recently departed Stephen Hawking is apparently back from the dead, now a target for scammers wanting to extract some quick cash from the unwary in the form of a vaguely surreal 419 scam.

The digital entropy of death: link rot
Hot on the heels of a grim blog about digital death comes…another blog about digital death. Except in this case, the recently deceased would be the links that tie the web together, otherwise known as link rot. Link rot is a weird thing. Say I blog for Puppy Chow and I write an article about the...

A cure for the common cold call: freeze them out
The phone rings and it's a number I don’t recognize. That’s enough to bring my mood down a few degrees. It shouldn’t, but unfortunately experience has taught me that at least 95 percent of the calls from numbers that are “private” or that I don’t have an account name stored for on my phone are...
GrayKey iPhone unlocker poses serious security concerns
Ever since the case of the San Bernadino shooter pitted Apple against the FBI over the unlocking of an iPhone, opinions have been split on providing backdoor access to the iPhone for law enforcement. Some felt that Apple was aiding and abetting a felony by refusing to create a special version of...

The digital entropy of death: what happens to your online accounts when you die
Unless you're planning on having your mind jammed inside some sort of computer chip, eventually mortality will catch up and you're going to have to work out what you'll do with all of your online accounts.
