I Practice locations clues in Street View.
Round 1: Colombia, South America.
The stop sign reads PARE, used by every South American country. Red-brick apartments, tile roofs and Andean hills support it.

Day 1/200 ✅ #200DaysOfGEOINT
Short on time today, so I started with the GeoGuessr daily challenge: 10,536 pts. Round 2 scored 0, but a road sign to Sarreguemines (D35) would have placed it in France.
Lesson: read the signs first. Tomorrow we go harder.

Starting a 200 Day GEOINT Learning Challenge. 🌍
Inspired by Rainbolt video on a 4-year geolocation mystery, I'm building on my experience through daily @geoguessr and real case studies
I already have some experience in #GEOINT, but I want to take it much further.

This is one of the best geolocation case videos I've watched so far.
The storyline and the investigative process behind it are fascinating.
If you haven't seen it yet, it's well worth your time.
Great work by @georainbolt 🙌

PHP2Shell and the Node.js Brotli Flaw: A Practical Response Guide.
PHP2Shell: patching the server may not fix your app.
Container images carry their own PHP or Node.js runtime, and running processes keep the old code until restarted.

Threat Intelligence in Practice
Collecting indicators is easy. Knowing what to trust, what to do next, is the hard part.
This guide breaks the work into four steps: collect, verify, contextualize, decide. Each one is mapped to free-tier tools analysts can use.

Clean Desk & Screen Lock
Not every attack starts online. Sometimes it starts at an unattended desk.
Lock your screen every time you step away. Just for a second, is all it takes.

#GEOINT Resource OldMapsOnline.org
I used OldMapsOnline in a recent investigation to verify how a location changed over time. it confirm the age of a structure, and trace a boundary or road that no longer exists.
It is a search gateway to historical maps held by libraries
Day 5 #CyberAwarenessMonth
The password expiration myth: changing your password every 30/60/90 days doesn’t automatically make you safer.
Use strong, unique passwords + MFA, and change them when compromise is suspected.
Security > routine password changes.

DAY 4 OF #CybersecurityAwareness
Credential Reuse
Why is password reuse dangerous?
1. One breach could expose multiple acct’s.
2. Your email account could become a gateway to other accounts.
3. Personal and work acct’s sharing
passwords can increase the impact of a compromise.
Day 3 of #CybersecurityAwarenessMonth
Why You Need a Password Manager
A password manager helps you👇
1. Generate strong unique passwords for every account.
2. Store them securely.
3. Autofill your credentials when needed.
More details 👇
@CyberRealm_HQ
Why consider a passphrase?
Length can make it harder to crack.
A unique passphrase for every account helps limit the impact of a breach.
Remember.
Use long, unpredictable passwords or passphrases.
Never reuse credentials across accounts.
stay cyber secure 🤝.

Passphrases vs. Passwords
Think your password is strong enough? Let's talk about passphrases.
Passwords combine letters, numbers, and symbols.
Passphrases use multiple words to create a longer, memorable secret.
