TWINN #108 Blank image phishing

Today is our first day of bootup training, so I have to say it’s always exciting to see a screen full of new nerds starting up their adventure within Nerds On Site. It doesn’t take more than a few minutes to connect the dots of our world of free enterprise, with nothing but opportunities, with new nerds!

This week, we’ll start with a brand-new phishing scam.

What happens when all our training goes out the window, and we get an email from a trusted source like DocuSign with a blank image? Given the subject of my weekly updates, it probably doesn’t surprise you that this is the latest stealthy phishing attempt involving using already-authorized channels like digital signatures from DocuSign. Still, when the blank image is clicked, then there’s base64-encoded JavaScript that is triggered, causing your browser to visit a malicious site.

Chinese Hackers Exploited Recent Fortinet Flaw as 0-Day to Drop Malware. The key here is that even two weeks before the vulnerability was known and/or disclosed, it was used by some Chinese threat actors.

Finally we have end-to-end encryption in iCloud data with iOS 16.3. This is exciting, especially for those who started to wonder about the future of Apple and our data sovereignty.
