Spoofing
What is it and how can we defend against it.
Spoofing is a deceptive tactic used in cybersecurity where an attacker disguises themselves as a trusted source to gain access to sensitive information, spread malware, or manipulate systems. The goal of spoofing is to trick victims into believing that the communication or source is legitimate, thereby lowering their guard and increasing the likelihood of a successful attack.
Common types of Spoofing:
There are several types of spoofing, each targeting different communication channels or technologies:
Email Spoofing: This is one of the most common forms. Attackers forge the sender’s email address to make it appear as though the message comes from a trusted source, such as a colleague, bank, or government agency. These emails often contain malicious links or attachments designed to steal personal information or install malware.
Caller ID Spoofing: In this type, attackers manipulate the caller ID to make it look like the call is coming from a known or trusted number. This is frequently used in phone scams to trick people into revealing personal or financial information.
IP Spoofing: Here, attackers send data packets from a fake IP address to disguise their identity or impersonate another system. This is often used in denial-of-service (DoS) attacks to overwhelm a network or server.
Website or URL Spoofing: Attackers create fake websites that closely resemble legitimate ones, such as online banking or shopping sites. When users enter their login credentials or payment information, it is captured by the attacker.
GPS Spoofing: This involves sending false GPS signals to mislead a device about its actual location. It can be used to manipulate navigation systems or track movements inaccurately.
MAC Spoofing: Attackers change the Media Access Control (MAC) address of their device to impersonate another device on a network, often to bypass access controls.
Why it’s dangerous:
- Can lead to identity theft, financial loss, or unauthorised access to systems.
- Often used as a first step in larger attacks like data breaches or ransomware.
How to protect yourself:
- Verify suspicious messages or calls through a second channel.
- Use multi-factor authentication (MFA).
- Keep software and antivirus tools updated.
- Be cautious with links and attachments in emails.
