Chapter 1: Key Cybersecurity Attacks

In this article, we delve into 100 vital cybersecurity concepts essential for developers aiming to create secure applications. To enhance clarity, the information will be segmented into multiple posts. This content is purely educational and not a promotion of malicious practices.

The previous parts of this series can be found below:

61. Denial-of-Service (DoS) Attack

A DoS attack overwhelms a targeted machine with more requests than it can handle at any given moment, rendering it inaccessible to legitimate users.

62. Distributed Denial-of-Service (DDoS) Attack

This variant of a DoS attack involves numerous compromised machines collectively sending excessive requests to a target system, aiming to incapacitate it.

63. Botnet

A botnet comprises a network of infected devices, also known as bots, controlled by a malicious entity called a bot herder. These bots work together during DDoS attacks.

64. Degradation-of-Service Attack

In this attack, compromised machines, termed Pulsing Zombies, send requests to a target intermittently, causing the system to slow down instead of crashing entirely.

65. Permanent Denial-of-Service (PDoS) Attack

This attack focuses on hardware, aiming to render it completely inoperable by corrupting firmware or targeting critical components. The BrickerBot malware exemplifies this type of attack on IoT devices.

66. Fork Bomb

A fork bomb is a denial-of-service technique where malicious software continually replicates itself, consuming all CPU resources and making the machine unavailable.

67. Memory Leak Attack

Memory leaks occur when a developer neglects to free up memory that is no longer in use. If an attacker exploits this flaw, it can lead to memory exhaustion, similar to a DoS attack.

68. DLL Injection Attack

In a DLL injection attack, a commonly used Dynamic Link Library (DLL) is manipulated to become malicious, allowing the attacker to insert harmful code into a running process.

69. Buffer Overflow Attack

When a buffer exceeds its storage capacity, it can overwrite adjacent memory regions. This overflow can cause a system crash or enable the execution of malicious commands.

70. Chaos Engineering

This practice involves testing the resilience of production systems against infrastructure and application failures. Tools like Chaos Monkey and Facebook's Project Storm help ensure service reliability during unexpected outages.

The video titled "Cybersecurity Essentials for Developers - Intro" provides an overview of these critical concepts. It is a great resource for developers looking to enhance their understanding of cybersecurity principles.
