When an Entire American City Was Crippled by Ransomware - The Saint Paul Cyber Attack Reality Check

Last July, an absolutely devastating ransomware attack hit Saint Paul, Minnesota, causing one of the worst cybersecurity incidents in American municipal history.
The entire city’s computer systems were paralyzed, network communications failed, citizens couldn’t pay their water bills, libraries lost Wi-Fi access, and even city employees couldn’t work.

This turned out to be a ransomware attack orchestrated by a hacker group called “Interlock.”
What’s infuriating is that when the city refused to pay their demands, these criminals released 43GB of citizen data onto the internet..

Let’s examine exactly what happened and what we can learn from it.

iPhone 17 Air 2-Week Real Experience Review - Surprising Differences from 16 Pro Max

Being thin doesn’t automatically make something good, right?
Samsung’s Galaxy S25 Edge made a big deal about being thin, but when I actually used it, that’s all there was to it.
So when I saw the iPhone 17 Air announcement, I thought “Here we go again with the thinness bragging.”
5.6mm thick and 165g… Just looking at the numbers didn’t really impress me.

But after actually using it…
Oh wow, this is on a completely different level.
I’d been using the 16 Pro Max as my main phone for over a year, consoling myself with “it’s heavy but the performance is good,”
but the moment I held the Air, I realized how much I’d been suffering.

Just two weeks ago, I was thinking “if I’m buying the Air, might as well just get the 17 Pro,”
but now my mind has completely changed.

The shortcomings like the mono speaker and single camera pale in comparison to
the incredible satisfaction this lightness and thinness brings.

Honestly, I’m still amazed at how much more satisfied I am than I expected.

Similar incidents of fake text messages being distributed occurred in Bangkok, Thailand, Malaysia, and New Zealand.

Let’s find out what’s really happening and what we need to do about it.

South Korea's Consumer Recovery Coupon Policy - A Case Study in Digital Security

South Korea is implementing its 2nd Consumer Recovery Coupon program, distributing 100,000 KRW (approximately $75 USD, equivalent to about 2-3 meals at a mid-range restaurant in Korea) per person starting September 22nd.
This nationwide initiative targets 90% of the population as part of economic recovery efforts.
