Assessing an Email’s Legitimacy

Assessing an Email’s Legitimacy

| | email, Phishing, security
I recently received an email sporting “Wells Fargo” logos. It asked me to do a survey. It was actually sent from the domain ‘morpace.com,’ which used to belong to a product survey company. When I googled the name ‘morpace’ the first thing I found was that the company had probably ... Read More
Beware of Phone Phishing

Beware of Phone Phishing

Just because the email (or letter) directs you to a phone number doesn’t mean you aren’t being phished. The nearby image shows part of a recent phishing email. It claims that I ordered a laptop/tablet from Microsoft for delivery to an unfamiliar address in Las Vegas. I’ve warned readers in ... Read More

FCPX and the Solo Studio

In other posts I describe how I’m producing videos for a Coursera specialization. This is a solo operation. I don’t have someone to hold the camera or answer the phone while I’m recording. When things go well, I produce exactly two, audio-synced video streams: the slide show presentation and my ... Read More
“Eyes Only” Revisited

“Eyes Only” Revisited

I was poking around declassified documents from the National Reconnaissance Office (NRO) and found a reference to “Eyes Only” from when they reorganized their BYEMAN control channel in 1993. They seemed to use it to indicate material “above Top Secret.” In an earlier post I argued that “Eyes Only” meant ... Read More

Self-teaching a little security thinking

More interesting for me were its recommendations on conducting a secure conference at the endpoints. They discuss ... Read More

Detecting a Phish on an iPhone

| | Apple, email, iPhone, Phishing, security
In their obsession with simplifying the phone interface, the iPhone designers make it a bit harder to detect dangerous emails. Here is an email claiming to be from “Humana Health” asking me to pay for my COVID-19 insurance, whatever that might be. The structure, layout, and English are convincing. The ... Read More

Life Cycle of a Security Bug

Life Cycle of a Security Bug

| | attacks, flaws, security, zero-day
Unlike members of the insect family, computer software bugs live forever. Software security bugs (well, flaws) are especially troubling since they demand respect from every software developer now and forever. We want to believe we can “eradicate” software flaws through reviews, testing, and vigilance. Eradication is a myth. A flaw’s ... Read More
