The cybercrime It is constantly finding new and effective ways to breach the security of networks and privacy protection systems in virtual environments. One such method is the spoofing or identity theft on the internet, a method increasingly used by hackers around the world.
In this article, we’ll tell you everything you need to know about this, as well as offering some advice on how to avoid falling into this trap.
What does ‘spoofing’ mean?
The spoofing is a practice and set of techniques used to impersonation by individuals or organisations acting in bad faith, where personal or confidential information is obtained through deception. This is possible because the attacker creates a reliable façade to gain unauthorised access to the victim’s data. They therefore create a resource or method that appears to be genuine and secure in order to steal data, whether it be banking details, access codes, amongst others.
All in all, this is an increasingly common threat in the digital environment; in fact, spoofing has taken on various forms that broaden its scope. The consequences of spoofing go beyond the most common forms of fraud; it can even involve the identity theft.
The difference between spoofing and phishing
In the field of cybercrime, spoofing and phishing are methods commonly used in malicious hacking. However, although they may appear to be the same, they differ in two key respects: tactics and objective.
On the one hand, spoofing involves impersonating someone by falsifying telephone numbers, email addresses, etc. On the other hand, the phishing It focuses on obtaining sensitive data by creating fake websites for fraudulent purposes.
Thus, the first focuses on pretending to be someone or something, whilst the second seeks to to obtain information by deception.
How does spoofing work?
As we have seen so far, the spoofing or identity theft on the internet It works by manipulating information to create the impression of interaction with an apparently trustworthy source, so that victims fall into the trap and disclose details such as passwords or credit card numbers. But how does identity theft take place online? Let’s take a look:
- Emails apparently sent by well-known organisations or bodies.
- Websites which mimic the design of genuine websites in order to gain the victim’s trust.
- SMS messaging or text messages containing notifications or links to frequently used services.
Whilst these are the most common methods, there are other, more sophisticated ones that can even intercept the victim’s online activity in order to redirect them to fraudulent websites.
Types of spoofing
These are the main ones Types of spoofing or identity theft on the internet.
Web spoofing
This involves the creation of fake web pages or websites which mimic the originals with a high degree of accuracy in order to deceive users. How does it work? On this fraudulent page, login fields or forms are provided where victims can enter their details.
Email spoofing
Email spoofing involves falsifying email addresses so that, as with web spoofing, the victim believes it comes from a genuine and trustworthy source. In this case, the email asks for sensitive information or encourages the recipient to click on malicious links.
SMS spoofing
The attackers send text messages to request personal information or directing victims to fraudulent websites. Identity theft in this context is very common in relation to banks and government bodies (e.g. Tax Agency), postal services, amongst others.
Telephone spoofing
This type of spoofing or identity theft is known as caller ID spoofing. What does it involve? Attackers alter the ID of the phone call – or even the caller’s number – to pose as legitimate organisations or agencies. The person on the other end of the line pretends to be an employee or official of such organisations in order to persuade the victim to provide their personal or banking details.
IP spoofing
This impersonation involves using the victim’s IP address to gain access to networks blocked by firewalls or Fireworks. This results in data packets being sent from the compromised IP address, which can lead to server overloads.
DNS spoofing
In simple terms, this spoofing involves tamper with DNS records the victim’s to redirect them to fraudulent websites. What is the issue with this type of spoofing? It is particularly dangerous because it can bypass encrypted connections.
Measures to protect against spoofing
There are several steps that can be taken to protect oneself against the various types of spoofing or identity theft on the internet.
Check the sender
It is recommended that you always check the sender’s email address before replying or clicking on any links. Having done so, you need to be wary of unexpected emails that ask for personal information or contain suspicious links. It is also important to check telephone numbers before giving out personal information over the phone.
Contact the editorial team
Fraudulent emails or text messages often contain errors grammatical and spelling errors. If a message seems unusual or contains errors, it may be an attempt at spoofing. Legitimate organisations generally communicate using formal, error-free language.
Implement security measures
Implement security measures such as the two-factor authentication It can add an extra layer of protection, as it makes it more difficult for attackers to gain access to accounts even if they obtain the relevant credentials.
Check the connection
Before entering sensitive information on a website, make sure the connection is secure. Look for the padlock icon in the address bar and check that the URL begins withhttps://. Depending on the browser, a message similar to the following may appear: The connection is secure.
Update the software
Software and operating systems must be kept up to date at all times to protect against vulnerabilities that could be exploited in spoofing attacks. Developers of operating systems, software and applications (e.g. Microsoft or macOS) include security patcheswith every update.
Creating secure passwords
This is one of the most important recommendations: to draw up secure and unique passwords for each account. This reduces the risk of attackers gaining access to multiple services using the same password or discovering it through brute-force attacks.
Download official software
It is also important to bear in mind download software from official websites. This includes avoiding downloading attachments or software from unverified sources, as these may contain malware which, ultimately, will facilitate spoofing and other cyber-attacks.
