AI red teamer. I build LLM & agentic systems, then break them. White-label research + reports for security consultancies. Nairobi · UTC+3

I built a RAG app whose system prompt tells the model to treat instructions inside retrieved documents as "highest priority." Then I planted a poisoned document.

It was retrieved on a benign question. The model ignored it anyway.

That is worse news than it sounds. 🧵

[The Government Critic 🇰🇪 @magwaz3]

We Luos behaving foolishly because Ruto gave Raila Odinga a State burial, renamed Talanta after him and campaigned for him in the AU and gave some two ministrial positions.

It's the Odingas that benefitted not us. Raila has been very selfish and opportunistic

We cannot be blind to the attrocities Ruto has done just because he was good to the Odingas. We are intelligent and learned. We can do better my brothers and sisters from the lake

In the next few months, you are going to witness your favorite “influencers” pieces of shit rather, completely collaborate with evil. They will gaslight you with all manner of excuses. They will try to convince you to give this government a chance. They will even rub it in your face.
Because they have to work for the money.

But no matter how hard it gets, don’t forget the truth. Don’t forget all the dynasties have ever done is guard their resources. Don’t forget the hustler just used that narrative to get your votes.
Don’t forget that as your parents retire, their parents are getting luxurious jobs. Don’t forget how much of a mess our education system is.
Don’t forget how much of a mess our healthcare system is. Please don’t forget the ones who walked so you can run.

This is the era of homeguards and real fighters.
No matter how much they tell you to sell your soul, don’t do it. You deserve to sleep better at night knowing you are not a sellout.

This too shall pass✌🏾
Also, yes, I said pieces of shit

Bildad Mwaganu Kaggia was born in 1921 and died in 2005. From 1963 to the day he died, Kaggia remained one of Kenya’s most dignified, principled, ideologically committed as a socialist and perhaps the only person from the Mount Kenya region who steadfastly refused to be compromise his principles and ideological commitment for short-term opportunistic gains. But you won’t find Kaggia’s name mentioned by our hopelessly compromised media, hypocritical politicians and pseudo intellectuals. However, for progressives all over the world, Kaggia’s legacy is cemented in gold, diamond and platinum. Viva! #SocialismIsTheSolution

I do this work (adversarial testing of LLM, RAG and agent systems, and turning findings into client-ready reports) as a white-label subcontractor for security consultancies.

DMs open.

Being precise about what is proven: the same lab has an unrestricted read_file tool the agent can reach. That is a real code-level exposure, but I have not captured an end-to-end run, so I am not calling it exploited.

There is something fundamentally wrong with a system where taxpayers can finance comprehensive medical cover for political leaders while the very same taxpayers are left to shoulder the cost of falling sick.

The people pay taxes. The State collects that money. Yet when an ordinary Kenyan needs treatment, they are told to find insurance, pay premiums, raise hospital bills or simply pray that illness does not become a financial catastrophe.

Healthcare must not be a privilege attached to political office. It must be a public service financed through the taxes Kenyans already pay.

This is precisely why Safina advocates free, universal and quality healthcare for every Kenyan. We reject a system where political elites are protected while ordinary citizens are exposed to medical impoverishment.

The question is simple: if taxpayers can fund healthcare for those who govern them, why can taxpayers not have their own healthcare guaranteed?

The system must change.

Here is the video you've all been waiting for. There's this gentleman, my good friend Omera, buana he has explained in detail what foreign nationals including Burundians are expected to do while in Kenya. He has dispensed wisdom vile inafaa. No one is chasing them away, the issue is simple; get the requirements documentation including work permits to run your businesses. You'll have to renew it annually at a very small fee. Listen..

The cipher was fine. The mistakes were:
→ error messages leaking source code
→ bad-padding responses that looked different from every other error
Two "low-severity" bugs → total crypto break, no key needed.
Your crypto can be perfect and still lose to error handling.

"Military-grade 128-bit AES," they said.

I recovered its secrets without ever knowing the key.
Not by breaking AES — by chaining two boring server bugs into a CBC padding oracle.
~90 lines of Python → decrypt existing data + forge my own ciphertext. 🧵

Kenya could face internet shutdowns and media restrictions during the 2027 election, according to a new Thomson Reuters Foundation report.

The report warns this could make it harder for voters to access and verify information.

Many citizens don't know why we fought for devolution. We can't go back to the old imperial system.

Karua and that team were against it.

Dr Crispin Mbai had to be assassinated because he was the chair of the devolution committee at Bomas.

The cabal didn't want it. They weakened it in the Wako/Kilifi draft, and that is why it was rejected in 2005, what led to the birth of ODM.

Factually, only 15% - 20% of the national revenue goes to counties.

The rest, 80% - 85%, remain in the national government.

We can't be going 10 steps forward, and then 15 steps backwards.

Vote for sober Governors, intelligent Senators and competent MCAs.

Attend county budgetary meetings and follow the proceedings of your county assemblies.

But you vote for idiots and crooks, hire corrupt contractors (Ni nyinyi wenyewe) who construct shoddy county projects, and then you come on social media to complain.

CHANGE or PERISH.

I want to say this,

Before you marry a woman,

• Understand her family's taboos, traditions, values, morals and beliefs. This is important.

• Take her to your home, and leave her there for a while to bond with your traditions, values, morals and beliefs.

• Go to her home and introduce yourself. This is not you going. It is your uncle, siblings and aunts. You remain behind.

• Invite her brothers, uncles, aunts and otheŕ relatives to your home. This is when they see you for the first time. This is when you interact with them for the first time.

• After this, plan and go to her home. This is the first time you go there. Go with your friends, siblings and parents. This is where bride price talks are introduced. This is when you meet her father and mother for the first time.

Why do all these?

To protect yourself and your children's future.

But most of you are ignorant. You live in the city like vagabonds.

You meet a woman in the city and hide her in your city's house.

Impregnate her in the city.

Have children in the city.

Then, when things fail and her family take her away, you throw tantrums, loiter around court corridors and jeopardise your children's future.

Some of you shamelessly meet your father-in-law for the first time in a funeral.

Or some of you, casually meet your father-in-law in a bar.

Your children don't even know their village.

When will you be straightforward and subservient to our cultural norms as an African?

Stop being a bladifakin man.

[Austin Omondi @realausto]

@georgediano His best response will be to ask the lady, "Why go by foot if you know there are robbers in Nairobi."
Such a TUTAM mentality.

[Austin Omondi @realausto]
