@TobyCastle3 First of all, loved watching it! I keep talking to the screen saying "the info is there, right in front of you!"
Secondly, one of the first answers is incorrect, and technically I wouldn't count a video screenshot as a "photo" 🙃
But overall was still great! ❤️

[Sofia Santos @Gralhix]

@daisyhunted It's marked as easy but it's full of traps 😉
It's a perfect example of the importance of verification.

[Sofia Santos @Gralhix]

@bellingcat is an absolute powerhouse in OSINT resources. If you haven't checked their website, toolkit, and discord channel you're definitely missing out!

"A day in the life of an investigator: Inside the world of open source at CIR"
In this article me and Erin talked about how got our jobs, our typical work day, tools we use, what is the best part of the job, and tips on becoming an OSINT analyst at CIR.

@oculus969 @OSINT4Fun_eu I was aware that people would be busy with many challenges, so I didn't want to create ones that could be long and frustrating.
The goal was to make them fun and related to christmas so mission accomplished! 😁

[Sofia Santos @Gralhix]

How are you getting on with OSINT Advent challenges? I'm struggling a bit.. mostly for time but some got me stumped! (I'll get there.. maybe)
Today my final @OSINT4Fun_eu challenge was released. It was an easy but fun one. Did you get it right? 😉

Can men and boys also be victims of gender-based violence?

In West Africa, some young men are forced to fight in conflicts they never chose, recruited by armed groups trying to escalate long-standing tensions.

Tragically, many are unfairly labelled as fighters simply because of their gender.

At CIR, we’re working to uncover stories like these and show that violence doesn’t discriminate - it traps people in cycles of pain and loss, often tied to damaging ideas of masculinity.

Let’s first recognise that men and boys can also be victims and survivors of gendered violence - and that any longterm solutions need to include them and their experiences.

@Ashishdangwal07 Best way to learn!

[Sofia Santos @Gralhix]

@zessx Definitely an improvement!

[Sofia Santos @Gralhix]

@zessx Ah thank you! It's the first time I ever read a geolocation walkthrough with no images at all.

[Sofia Santos @Gralhix]

@osintupdates247 @IntelTechniques @OSINT_Community Amazing! Thank you for including my book suggestion ❤️ 📖

[Sofia Santos @Gralhix]

@SimSimIV I would buy it! Just needs a title that would fit the cover of a book 🙃

[Sofia Santos @Gralhix]

"What OSINT books do you recommend?"

I used to list this on my FAQ page, but I didn’t get asked often enough to keep it there. Clearly a mistake because I was just asked again! 🙃 So here’s my answer:

[Sofia Santos @Gralhix]

@JoshSimple66456 I also really enjoy watching his process. He's skilful and entertaining, a great mix!
I hope he keeps doing them 🙂

[Sofia Santos @Gralhix]

That said, I do recommend "Psychology of Intelligence Analysis" by CIA vet Richards J. Heuer Jr. It’s timeless for metacognition, perception, and avoiding bias. And you can access it for free at the CIA website: https://t.co/9qDY3nQGQq

[Sofia Santos @Gralhix]

Honestly, I can’t recommend OSINT books because I haven’t read any 🤷‍♀️.

OSINT relies on online data, and the internet changes constantly. Tools come and go, but the real core is analytical skills, adapting to change, and critical thinking.
