A really really big company was confirmed to have been compromised. They primarily handle work-force outsourcing and call-center stuff.

The amount of data this company possessed was SICKENING and over ONE PETABYTE of data was stolen.

I'll do a write-up on it later. It'll take me 45 minutes to discuss everything that was stolen and how many things it impacts.

Dawg, we have GOT TO STOP giving random companies user data.

"hey smelly how do i learn malware reverse engineering?"

I DONT KNOW.

I never took classes, I barely read any books on it. I learned C, malware dev, then I somehow magically learned asm and reverse engineering

I learned backwards. You figure out a better way

International Cyber News Digest, or whatever the account was called, got banned from Xitter. It is currently not known why. His ban is mysterious like a mysterious guy in a mysterious thing (I'm good with analogies).

He was banned in the wake of the Threat Actors who compromised the Syrian government social media profiles.

Him and I were banned at roughly the same time. However, I was immediately unbanned. He was not unbanned.

He has filed multiple appeals yet they are denied. Additionally, he is not provided a reason why is banned from the platform.

He has been messaging every day since the ban trying to make sense of his ban. He has formally requested I assist him. He told him me if I can determine why is banned, or help him get unbanned, he will provide me with pizzas. Yes, this is plural. This is more than one pizza.

Hence, I am now using my large platform to state something akin to "Free my boy, International Cyber News Digestion, he's innocent, he didn't do anything wrong!"

I unironically believe his ban was incorrect and the result of a botched AI system. However, my protest is driven by my desire to consume foods high on saturated fat and grease.

FREE MY BOY INTERNATIONAL CYBERSECURITY NEWS DIGESTIVE SYSTEM

HE DIDNT DO ANYTHING WRONG

Yesterday Florida Attorney General James Uthmeier confirmed legislation has passed which explicitly forbids individuals under the age of 14 from being on social media.

However, no information has been produced which states how social media and/or tech companies will reliably ensure people under the age of 14 are not on social media.

The most likely answer is social media and/or tech companies will do age verification using drivers license and/or passport.

If companies do not comply with the new legislation they will be sued and/or criminally prosecuted.

This will inevitably result in social media and/or tech companies in general to advocate for age verification at the Operating System level (as Mark Zuckerberg has already stated multiple times on the record).

This will shift legal liability away from them.

If the social media websites successfully persuade government authorities to move toward OS-based age verification, this will bind your identity to your Operating System in the age of AI.

It's International Women's Day.

Thank women for raising the age of consent.

One of the biggest activists groups for raising the age of consent was the Women’s Christian Temperance Union.

In the 1800's the age of consent in the United States was 10. In some states, such as Delaware, it was 7.

The WCTU pushed heavily to protect women from sexual exploitation, prostitution, and physical violence.

Obviously the history is more complex than just one group of women did something, but they were a major driving force.

Okay, I'm tired of writing now. Here are some other topics to schizo rant about later:
- Why mutation engines are less common now
- How mutation engines are effective and also not effective
- How you can make code change
- Different types of mutation engines
- Mutation engines in different programming languages
- Why some things are engines and why some aren't
- Anime

Because people asked, "what's a Polymorphic Mutation Engine?", we'll talk about it. Truthfully, the name sounds kind of dangerous, or exotic, but in theory and implementation it's not too bad. The primary issue is it requires some prerequisite knowledge and if you don't have it, it gets funky and goopy really fast.

If you're familiar with high-level programming with class inheritance, this is not the same as object oriented polymorphism.

When coding (in literally any language) there is a concept of a mutation engine. As is tradition, it sounds fancy, but if you break it down it makes sense.

What's an engine? If you think of an automobile engine (beep, beep), it's what propels the vehicle forward using a bunch of really small explosions, or something, whatever the fuck "combustion" is.

Likewise, an "engine" in programming is something that takes something in and it results in ... a result.

An engine in a vehicle takes gasoline (something in) and the engine results in "a result" (propulsion, vehicle being able to move). You have a lot of different engines in programming such as search engines, rendering engines, game engines, etc.

In that particular case, a Polymorphic Mutation Engine receives something (code) and then mutates it (changes it). It is called "Polymorphic" because it means Poly (many) - Morph (changes). It changes many times.

I have finished my Polymorphic Mutation Engine. It is very silly.

I spent hours, probably 6 hours or more, debugging trying to figure out why it wasn't mutating correctly.

Then it dawned on me Visual Studio was optimizing out segments of my code which made it break.

Today Donald Trump fired Kristi Noem (lady in charge of DHS) while she was live on television.

I have never seen someone in this prestigious a position fired on live television (or any position, for that matter).

I'm not implying anything with this post.

But, it made me very, very, very, confused. I'm working on this new code thingy, check the internet, and I see this lady fired while she's doing a live press conference, she didn't even know she was fired yet and the banner on the screen says shes fired.

Does your child check the weather?

Well think again, because pedophiles also check the weather. If your child checks the weather they may be a victim of sexual exploitation.

Yesterday Troy Hunt shared this photo online. You have to do age verification to check the weather.

United States government big mad this week as a whistleblower leaks government documents on the internet.

Basically, the Department of Interior documents leaked showed the United States government plans on removing themes from National Parks about African American stuff, LGBT stuff, Climate Change, etc.

A Spokesman from the Department of Interior has stated the documents are edited and are intentionally misleading.

The biggest surprise is these documents were not leaked onto World of Tanks

Mutation engines have two different components.
1. The thingy you want to change (code)
2. The thingy that does the changes (the engine).

How you implement both these components is tricky because you have to solve problems such as:
1. Where am I going to store the code that changes?
2. How will the engine make sure each "change" is unique?

Many people have the false belief that a mutation engine means the code changes as it runs, but that isn't necessarily true. While that is technically* possible, it is exceptionally rare and profoundly difficult to implement in any reasonable manner. How self-rewriting code is implemented is outside the scope of this, but it is only achievable with assembly (to the best of my knowledge, I haven't seen it in any other language).

Mutations usually occurs during "mutation events", basically a time when a program can safely change itself without everything imploding. These are usually:
1. Compilation time
2. Infection time
3. ???

Primitive mutation engines change when the binary is compiled. There are many examples of this online. The code is the same, but when you click "build" the result is different each time (the .exe looks different). This is achieved (usually) with a bunch of fancy macros.

More sophisticated mutation engines change code when it infects another program. How this is achieved is also kind of outside the scope of this because it requires a pretty heavy prerequisite knowledge on Microsoft PE files (.exe or .dlls).

??? because this is basically any other time your code can change without is imploding into itself. In my case, with my Polymorphic Mutation Engine, my program changes itself each time it terminates. In other words, when it finishes running and Windows says "ok mr. program go back to the harddrive", this is when my code takes the opportunity to mutate.
