- How Hackers Exploit Spring Core Vulnerability in 2025: Proactive Measures to Detect Emerging Cyber Threats
API management has emerged as a critical and strategic factor in staying ahead of the market leaders. However, digital transformation has significant disadvantages, such as opening the door to hackers.
Hackers have been quick to take advantage of a serious flaw in Spring Core, commonly known as SpringShell or Spring4Shell among security experts. The cybercriminal sends a specially created query to the Spring Core framework's web application server.
- Fraud Detection in Mobility Services With Apache Kafka and Flink
Mobility services like Uber, Grab, FREE NOW (Lyft), and DoorDash are built on real-time data. Every trip, delivery, and payment relies on accurate, instant decision-making. But as these services scale, they become prime targets for sophisticated fraud—GPS spoofing, fake accounts, payment abuse, and more. Traditional, batch-based fraud detection can’t keep up. It reacts too late, misses complex patterns, and creates blind spots that fraudsters exploit. To stop fraud before it happens, mobility platforms need data streaming technologies like Apache Kafka and Apache Flink for fraud detection. This blog explores how leading platforms are using real-time event processing to detect and block fraud as it happens—protecting revenue, user trust, and platform integrity at scale.
The Business of Mobility Services (Ride-Hailing, Food Delivery, Taxi Aggregators, Etc.)
Mobility services have become an essential part of modern urban life. They offer convenience and efficiency through ride-hailing, food delivery, car-sharing, e-scooters, taxi aggregators, and micro-mobility options. Companies such as Uber, Lyft, FREE NOW (former MyTaxi; acquired by Lyft recently), Grab, Careem, and DoorDash connect millions of passengers, drivers, restaurants, retailers, and logistics partners to enable seamless transactions through digital platforms.
- How to Build a Real API Gateway With Spring Cloud Gateway and Eureka
API gateways are essential in a microservices architecture.
But building one that's real-world-ready, secure, scalable, and service-aware will require more than just wiring a few annotations.
- Memory Leak Due To Mutable Keys in Java Collections
Java Collections components (such as Map, List, Set) are widely used in our applications. When their keys are not properly handled, it will result in a memory leak. In this post, let’s discuss how incorrectly handled HashMap key results in OutOfMemoryError. We will also discuss how to diagnose such problems effectively and fix them.
HashMap Memory Leak
Below is a sample program that simulates a memory leak in a HashMap due to a mutated key:
