Cyber Attacks: Origins, Mechanisms, and Damages - A Thread 🧵

Malware:
Malware is a collective term for malicious software that is designed to infiltrate, damage, or gain unauthorized access to computers, networks, or devices.

Malware is developed by various cybercriminal groups and sometimes by state-sponsored actors with the intent of causing harm.

Common types include:
-viruses
-worms
-trojan
-ransomware
-spyware.

Malware can be spread through various channels, such as email attachments, malicious websites, USB drives, and infected software downloads. Once inside a system, it can perform various harmful activities like stealing data, encrypting files (ransomware), or spying on users (spyware).

Real-Life Example:
The impact of malware can be devastating, leading to massive data theft, system damage, financial losses, and operational disruptions. For instance, the WannaCry ransomware attack in 2017 infected over 300,000 computers across 150 countries, causing billions in damages and severely impacting organizations like the UK’s National Health Service (NHS). Denial-of-Service (DoS) Attacks:
A DoS attack aims to make a website, network, or service unavailable to its intended users by overwhelming it with traffic.

DoS attacks are launched by various actors, including hacktivists, cybercriminals, and state-sponsored groups, often as a form of protest or to disrupt operations.g

The attacker floods the target system with excessive requests or data packets, consuming all available resources and causing the system to slow down or crash. Distributed Denial-of-Service (DDoS) attacks involve multiple compromised devices (botnets) to amplify the attack.

Real-Life Example:
DoS attacks can cause significant downtime, leading to loss of revenue, customer dissatisfaction, and reputational damage. For example, the 2016 Dyn DNS attack, a massive DDoS attack, brought down major websites like Twitter, Netflix, and Reddit by overwhelming the DNS provider.

The Cybersecurity Threat Universe: A Thread Malware:

Malware is a term that describes any malicious software that can harm your devices or data.

Types of malware and what they do:

-Virus:
A code that inserts itself into an application and executes when the app is run. It can damage or delete files, corrupt data, or spread to other programs.

-Ransomware:
A type of malware that encrypts your data and demands a ransom for the decryption key.

-Spyware:
It collects information about your activities, such as passwords, payment details, or messages, without your consent.

-Trojan:
A Trojan disguises itself as a legitimate or desirable program, but performs malicious actions once installed. It can take control of your system, steal data, or download more malware.

-Worm:
A type of malware that spreads through a network by replicating itself. It can consume bandwidth, slow down performance, or damage network devices.
