In this post I take a deep dive into a fake CAPTCHA on a compromised website, and the multistage fileless loader that delivered the Lumma Stealer malware if visitors followed its instructions.

BlueSky is a relief. Healthy, comforting and reminding me what #twitter was. And what it has become. But, please: donΒ΄t leave #Ukraine over at twitter/X. They already fear - and feel - it. This is the moment when I decided to help πŸ‡ΊπŸ‡¦ with everything I can, with all the strength I have.

@milkman Yep. The world will pay the price. Now we've got to do more to focus attention on what he does before the midterm elections. In the meantime, there will be lots of people who will be astonished when leopards eat their face.

@blackburied I think we're in agreement here that Democrats should have pushed back harder when people started blaming them for inflation.

It would have been great to showcase personal stories of refugees. Apparently Americans need reminding that this country does not exist in a vacuum.

There is an American tradition of attributing the state of the economy – good or bad to whoever is in the White House. Democrats made a mistake by focusing more on Donald Trump than Kamala's plans to address food prices and housing.

 Hava Laudon and conservatives like her want an education system that conforms to their religious and racial views. Their religion and politics demand that children must never know about the existence of LGBT people or dark parts of US history.

Please pay attention to your local education races.

In past elections I have skipped over education elections on the ballot because education is not my specialty, and I don't have kids. This year, I'm so glad I took a few minutes to Google the candidates for Ohio's State Board of Education in southwest Ohio (5th district).

Mary E. Bineger is an education professional with a master's degree and many years of experience to back it up.

Hava Laudon's credentials are endorsements from GOP groups and a BS in Ministry Leadership from Moody Bible Institute. She supports sending taxpayer funds for education to private religious schools and has spread lies about LGBT people.

The choice is clear. Please don't skip over these races.

If anyone wonders why weakened encryption that the government can break is a bad idea, this is why.

The Russian cybercrime group FIN7 ran a network of fake AI undressing sites that delivered credential stealing malware to those who uploaded pictures. I gotta say, this is one group of cybercrime victims that I don't feel sorry for.

WTAF, Columbus?! The City of Columbus is suing a whistleblower who proved the City was lying when they claimed that no data had been taken in a ransomware attack. The City is trying to claim that because the data is only accessible via the ransomware gang's extortion site over Tor, it doesn't count. arstechnica.com/security/2024/

I live in Ohio: a state with a Republican legislature, Republican Govenor, and Republican Secretary of State. I was very pleasantly surprised to find that Ohio has sent a prefilled absentee ballot application to every registered voter. Way to go, Ohio! Seriously!

This is hilarious. Russia won't admit to their citizens that the war has crossed over to their side of the border β€” so their traffic cameras are still issuing speeding tickets to military volunteers trying to outrun Ukrainian attack drones! arstechnica.com/culture/2024/0

Regex isn't hard enough, so I present you with a crossword where all hints are regular expressions!

I confess at first it looked like the hints don't contain enough information to solve the puzzle but after some slow but steady progress I can confirm that they do 🀣

The original puzzle is from puzzles.mit.edu/2013/coinheist

I shared this on my blog: mathspp.com/blog/problems/rege

#puzzle #puzzles

A crossword puzzle in a hexagonal grid where all hints are regular expressions. The hints come from three different directions and therefore all cells of the grid have three overlapping hints.
