Examples of Ransomware Attacks

To effectively combat ransomware attacks, it is crucial to have a clear understanding of what ransomware is and how these attacks occur. This article will provide an overview of ransomware and the methods employed by attackers.

What is Ransomware?

Ransomware is a type of malicious software that encrypts files or locks users out of their systems until a ransom is paid. It is typically delivered through email attachments, malicious links, or exploit kits. Once the ransomware infects a system, it encrypts valuable files, rendering them inaccessible to the victim.

Attackers demand a ransom payment, often in cryptocurrency, in exchange for providing the decryption key or restoring access to the compromised system. However, there is no guarantee that paying the ransom will result in the recovery of files or the restoration of system access.

How Ransomware Attacks Occur

Ransomware attacks can occur through various techniques, each with the goal of infiltrating vulnerable systems. Here are some common methods used by attackers:

1. Phishing Emails: Attackers send emails with malicious attachments or links, posing as legitimate entities or containing enticing messages to trick users into opening them. Once opened, the ransomware is deployed.
2. Drive-by Downloads: Malicious code is injected into legitimate websites, exploiting vulnerabilities in the user's browser or plugins. Visiting these compromised websites can lead to automatic downloads and the installation of ransomware.
3. Remote Desktop Protocol (RDP) Exploitation: Attackers target weak or improperly configured RDP connections, gaining unauthorized access. Once inside, they deploy ransomware on the compromised system.
4. Malvertising: Attackers use online advertisements to deliver malicious code. Clicking on these ads can redirect users to websites hosting ransomware or trigger automatic downloads.
5. Exploit Kits: Exploit kits are toolkits that take advantage of software vulnerabilities to deliver malware. When users visit compromised websites, the exploit kit scans their system for vulnerabilities and installs ransomware if found.
