On today's Layer 8 Podcast, we have @shibasec.bsky.social from Maltego talking about CTFs and investigations, including one where he lifted the curtain on pig butchering scams. He found it to be a "scam as a service" offering with scripts, personas and more. open.spotify.com/episode/3fKd...

Since our CTF closed yesterday, I thought I would do a quick recap of the problems I encountered (and how to solve them) when writing challenges. medium.com/@shibaosint/...

How to write an OSINT CTF
I helped organise and create several CTFs in the last two years both for professionals and amateurs. In this blogpost, I would like to go…

Participants explored challenges with topics ranging from terrorist group, online casinos, WHOIS registries, PMCs operating in Africa to a Russian shadow fleet tanker. I had the pleasure to design the challenges along with the CIRAT team from @mercyhurst.bsky.social.

Both the school and the temple are in the same region, 40 km apart. Let's begin by exploring the road linking them on Google Street View: road number 2006. After a few minute we find the challenge's location: 13.9159829,101.8389441 (5/5)

The third sign will require a bit more work, OCR does not give us anything useful but both phone numbers give us a result for a web search: a school and a cattery. The cattery does not have an address listed on its page and has not posted since 2016, let's discard it. (4/5)

Cool open-source investigative tool I just learned about: alltext.nyc. It lets you search any text found in Google Street View images from 2007 to 2024— graffiti, shop signs, street text, you name it. Just type in what you see, and see what pops up.

ICYMI: on Twitter, an OSINTer ('Vleckie') is being blamed for a US airstrike in Yemen that killed 8 civilians. in a thread, she'd marked a group of houses as an underground bunker — from satellite imagery alone. those houses (not a bunker) were subject to a US airstrike. 8 innocent people dead.
a post by Vleckie: "Allright, time for me to go through the mud.
Based on satellite imagery I'd marked this quarry as an underground base, and tweeted is out as such. 
I'm fairly certain Centcom doesn't take their targeting data from Twitter, but this still is a very severe mistake."

By doing a reverse image search on the content of the Facebook post, we find this picture, showing which flag the people in our original photo are really holding. Several videos of the event have also been posted, not a single rainbow flag in sight.

Searching the picture on Google Lens leads us to a Facebook post mentioning a demonstration in Tinzaouaten (Mali). It doesn't contain the original picture, but there is a similar one with some of the same people. An FLA (Azawad Liberation Front) flag can also be seen: cyan, yellow, red and white.

🇲🇱🇷🇺 A Wagner affiliated Telegram channel posted this awkward photoshop yesterday, saying the people in the picture support LGBT rights, identifying them as "Azawad shepherds". Let's take this as an occasion to learn how to find the context of a doctored picture and prove the trickery 🧵⬇️ #Wagner #Mali
Caption:
🌴🇲🇱 Азавадские пастухи, как и их чубатые братишки, на самом деле стоят за западные ценности, чуждые здоровому человеку. Всë остальное, звучащее с их ротовых полостей, обман.  
ЛГБТ, бача-бази, скотоложество, наркотрафик, контрабанда золота и оружия, работорговля, терроризм - неполный перечень их борьбы.

Mathieu Gaucheler @shibasec.bsky.social · 01/04/2025
For more on that subject you can read this thread by @tatarigami.bsky.social in collaboration with @casusbelli.bsky.social on a similar convoy from earlier this year.

Mathieu Gaucheler @shibasec.bsky.social · 01/04/2025
The gas station in the background allows us to geolocate the footage easily. It was taken on a roundabout at 12.612658°, -8.044582°. Shown on the 3rd image is the position of the two video as well as the direction of the convoy.

Mathieu Gaucheler @shibasec.bsky.social · 01/04/2025
We can confirm that this is the same convoy shown in the first video thanks to the painted marks on the trucks as well as their license plates. Here are a few examples.

Mathieu Gaucheler @shibasec.bsky.social · 01/04/2025
104 trucks carrying a container, 3 tank trucks, 1 truck carrying a boat, 1 QY50KD crane from XCMG, 1 truck carrying a Lonking LG100DT diesel forklift, what appears to be towing and recovery unit Century 5230 from Miller Industries and 1 car bearing red crosses.

Looking for other sightings of that convoy, we find a longer, unedited video published by the Bamako based media Cap Mali: www.youtube.com/watch?v=xeaq.... The 20 minute long video shows: 12 pickup trucks/ cars, 19 pickup trucks with mounted gun, more vehicles listed below ⬇️

Thanks to the monument in the background, we can roughly geolocate that footage to the following coordinates: 12,637980°, -8,005060° (red area in the picture). Near the French Institute of Mali. I'll publish a detailed walk-through of the geolocation process on my Medium.

This first insight we can gather is that this is a military convoy, as indicated by the license plates of the vehicles (white letters on a black background) as well as trucks loaded with personnel wearing military fatigue. Source and more examples: francoplaque.fr/af/rmm/5882-....

In Viktor Orbán's Hungary you're perfectly OK organizing neo-Nazi concerts over and over again, even if you're part of a group banned/designated as a terror group in multiple countries But Pride, let alone protesting a Pride crackdown as an opposition party, gets you banned.

According to their Telegram channel, Africa Corps (Африканский Корпус) is opening new "selection points" (forgive the dodgy Google Translate output) in Kazan, Naberezhnye Chelny, Nizhny Novgorod and Krasnodar. Interestingly enough, the amount of money promised for signing up depends on the place.
