A common ask: why don't you update the Diamond Model paper with newer examples? No. I like to teach the earlier papers to imbue history into infosec. We're surrounded by the new and the "today" - I want to give space to what came before. #infosec #cybersecurity #ThreatIntel
It's important in #infosec to be a student of history because you will be able to scale. There may be 1.5M new threats today, but they're just variations on 3 threats from a decade ago. You can now solve the better #cybersecurity problems.
So, in my courses I don't teach the new to make it "relevant." I teach the old to expose students who likely have never read them and provide additional insight they would have lacked with only the "newest."

A thread on bad analysis. When #ThreatIntel analysts want to show off their Foreign Policy and Economist subscription status after reading the Russian foreign policy Wikipedia page /n #threatintelligence #cybersecurity #infosec Image
Most analysts who are "doing attribution" aren't doing good cyber threat intelligence, they're doing poor foreign policy analysis
They neither have neither the data nor the expertise to make even a moderately confident statement on attribution

False flag operations are very rare because they're risky and the blowback effects are bad. Interestingly, the risks increase the more "important" you are so the most powerful countries are less likely to conduct FF ops. /1 #infosec #cybersecurity #ThreatIntel
Traditional covert and clandestine operations are cheaper, less risky, and more likely to succeed than false flag ops. Importantly, not all attempts to redirect blame is a false flag but just considered standard covert ops. /2
False flags are also generally misunderstood and confused. For example, using Russian as an English speaker in malware is, by itself, not a false flag but rather just considered good covert practice. It doesn't attempt to place blame but just conceal the operators better. /3

This is terrible. Let me tell you why. THREAD #privacy #infosec #cybersecurity #COVID19 theverge.com/2020/4/10/2121…
First, health data has ALWAYS been considered protected and sensitive. Hence, the privacy requirements and oaths physicians abide by - courts have LONG recognized this privacy.
Here, we're going to have health data records tied to a person tied to a phone tied to a location. It's literally a real-time walking health report.

Yesterday made ciabatta for the first time. The bottom was slightly overcooked but flavor and texture was great. /thread Image
First, the “biga.” fermented the yeast, flour, and water for 24 hours to get a strong flavor. Image
Add more flour and yeast, let it rise another 3 hours. Image
