PUREVPNSecurityWhat is a poodle attack and how to protect devices from it?

Interested to know how security breaches could take your privacy down? A poodle attack is one of the data exploitations that you should know to counter. Many confidential websites, security data, and personal information are at risk of getting poodles but most people are unaware of this encryption flaw. To know more about what the Poodle attack is? How does it attack? And how to prevent it? You should read the guide below.

What do you mean by poodle attack?

Padding Oracle on Downgraded Legacy Encryption (POODLE) or CVE-2014-3566, refers to an SSL protocol that is used to steal confidential information. If the poodle attack is difficult to read, let us simplify it further. A poodle attack can decrypt encrypted data between a client and a server while exposing sensitive information like personal information, credit card details, or passwords. 

Is a poodle attack always risky?

Well, do you feel good if somebody gets to know about your information anytime without your consent? The answer is surely a no. So, even if your information is not sensitive, a Poodle attack is risky. This is because your identity and cookies can be sold or gain access to websites for unethical purposes.

How does a poodle work?

The process usually involves a middleman, called MitM (man in the middle). A middleman attacking cyber security snoops into your device in disguise. Then, he takes control of either your access or the person whom you are in conversation with. Here’s how it is performed:

  • MitM Attack: A hacker first acts as a relay to decode your conversations and get hints about your private information. The communicators believe that their conversation is secure but a hacker encrypts it or acts as one of the communicators.
  • Downgraded Attack: The intruder now forces the user to convert to SSL 3.0 protocols, which are now outdated due to the vulnerability of such attacks. Hackers make users shift to them by dropping their connections several times, during the MitM attacks. 
  • Poodle: Just as the SSL protocol is in place, the Poodle is performed and all unencrypted is presented to the cyber-thief in the form of text, which can be used unsanctioned.

How to prevent poodle attacks

Some of the old protocol versions of security and some new too and more susceptible to getting attacked by a poodle attack. Although some have been deprecated by the authorities, certain devices tend to connect to them automatically. Here’s what you can do to protect your system from a poodle attack:

  • Disable SSL 3.0 in your web browser and all other browsers. The validation technique provided by SSL is outdated as hackers have mastered its encryption, and usually, convert the potential targets to this protocol to attack.
  • Update your system to secure protocols
  • If you are using the TLS version, then make sure that it is TLS 1.3, which is more secure.
  • Using Google recommendation of TLS_FALLBACK_SCSV. It prevents SSL 3.0 attacks and also prevents downgraded attacks against TLS 1.1 and 1.2 protocols.
  • Try to use Poodle-protected browsers like google, Mozilla Firefox, and Microsoft.
  • Use a reliable VPN like PureVPN to protect your home networks.

Can you be poodle vulnerable?

The cipher suite is a term used to explain the algorithm of how your security protocols run providing encryption while data is being transferred from one connection to another. The form of data can vary, it can be a voice, text, call, document, or code. These cipher suites are encrypted to form a public key, and this key is then used to communicate further for hacking.

The poodle attack uses the least secure chain to perform its task. Cyber blockchain mode is used to encipher the encrypted data. So, if you are using SSL and TLS, you are more susceptible to poodle attacks. Also, if you are using unsecured websites then, Yes, you hold the right to be susceptible to a poodle.

What is Padding?

Padding is a technique used to prevent plaintext enciphering hackers from understanding real information. By padding the data, useful information is secured from beginning to end by mixing it with other irrelevant information which makes it difficult for cybercriminals to understand. The attackers get modified data or errors while accessing the data. This is the underneath technique that fails the attacker at the final level of Poodling. The plaintext they get after a lot of work gets them distracted and they might not then pursue the same information.

Using a VPN for added security

A Virtual Private Network (VPN) is a tool used to give your internet access protection against many threats like denial service, the man in the middle, phishing, and password attacks. So, if you are using PureVPN, then all your communication and data pass through a safe tunnel that gives a buffer to your confidential information. PureVPN has 256-bit encryption to make sure that nobody outdoes your encryption. With the best encryption protocols, PureVPN will stop the Poodle from happening in the first stage, to ensure that none of your information gets leaked to trespassers.

Final Word

Cybersecurity has become very important these days. With masterminds, competitions, and intruders, it has become a challenge to secure confidential information. With some techniques and due diligence, you can perform security for your digital presence. Problems like poodle, phishing, and malware can be trimmed by understanding their risks and practicing the correct ways to prevent them.
