MTN just told Nigerian banks something wild:

“Stop blaming us for SIM-swap fraud. If you want to use our numbers as your customer identity layer, pay us to secure it.”

At first, that sounds ridiculous.

After digging deeper… it actually raises an important infrastructure question.

[Chidanand Tripathi @thetripathi58]

A guy sat at his laptop ready to permanently delete his 15-year-old Gmail account.

He was getting 400 spam emails a day. Fake Best Buy receipts. Phishing links from "Netflix." Cryptic extortion threats.

He hovered his mouse over "Delete Account" and sighed: "I just want peace."

His coworker, a former email deliverability engineer, looked over his shoulder.

"Before you nuke 15 years of contacts and data, let me show you something. Your email isn't broken. It's weaponized. There are 22 ways you've been leaving the door wide open. Google won't tell you this because the data collection feeds their entire ad engine. Give me 14 minutes."

Here's what she showed him:

Hello Cyber friends, share this video with Cybersecurity beginners who may be interested in joining CyBlack Academy. Registration will begin soon and a new cohort is starting next month. All the best 💪

Weak passwords are one of the easiest ways attackers gain access to business systems.

A simple or reused password can expose your organisation to data loss, security breaches,& operational disruption.

Strengthening your password practices is a small but critical step.

@smartnakamoura Imagine a person who has a different DOB on his BVN, Bank account, WAEC and NIN. How did he managed to open a bank account with all these diff in DOB? Comm banks are more concerned about meeting up targets in quantity.

Caching (Redis, Memcached)

What is Caching?

Caching is the process of storing frequently accessed data in a temporary storage (cache) so future requests can be served faster. Instead of querying the database every time, the system retrieves data from the cache, reducing response time and server load.

Why Caching is Important

→ Improves application performance.
→ Reduces load on the database.
→ Enhances scalability and user experience.
→ Useful in real-time applications where speed is critical.

Redis

Redis (Remote Dictionary Server) is an open-source, in-memory data store often used as a cache, database, and message broker.
→ Stores data in key-value pairs.
→ Supports complex data structures like lists, sets, and hashes.
→ Provides persistence options (data can be saved to disk).
→ Commonly used in session storage, leaderboards, and pub/sub systems.

Advantages of Redis

→ Very fast (in-memory).
→ Rich data types and features.
→ Persistence support (RDB, AOF).
→ Suitable for real-time analytics.

Memcached

Memcached is a high-performance, in-memory caching system designed for simplicity and speed.
→ Stores data in key-value pairs.
→ Focuses only on caching (no persistence, fewer data structures).
→ Commonly used for caching database queries, HTML fragments, or session data.

Advantages of Memcached

→ Simple and lightweight.
→ Extremely fast read/write operations.
→ Scales horizontally across multiple servers.

Redis vs Memcached

→ Redis: Feature-rich, supports persistence and advanced data types.
→ Memcached: Lightweight, purely focused on caching.
→ Redis: Best for applications needing caching + extra functionality.
→ Memcached: Best for simple caching with minimal overhead.

Real-World Examples

→ Redis: Storing user sessions in large-scale apps like Twitter.
→ Memcached: Caching product details on e-commerce sites for faster page loads.
