Is WhatsApp safe?

WhatsApp, owned by Meta, is one of the most popular messaging apps in the world, with over 2 billion users. Although it offers advanced security features such as end-to-end encryption, questions arise about its actual data protection and privacy. Let’s examine to what extent WhatsApp is safe and what steps users can take to secure their data.

What security features does WhatsApp use?

Can WhatsApp be considered a secure messenger? To determine this, it’s worth analysing the app’s key features related to privacy and security.

End-to-End encryption

One of the pillars of WhatsApp’s security is end-to-end encryption. This means that every message is encoded on the sender’s device before being sent, minimising the risk of the content being intercepted by hackers or man-in-the-middle attacks. Once the message is delivered, it is decoded only on the recipient’s device, ensuring that only the sender and recipient have access to its content.

Disappearing messages

WhatsApp offers a disappearing messages feature, which automatically deletes messages after they have been read or written. This solution provides additional protection by eliminating the possibility of them being intercepted after the conversation has ended.

Security codes

Unique security codes, generated for each conversation, are another protective measure. This feature allows users to compare security codes, providing assurance that the confidential information contained in the message is accessible only to the intended recipient and cannot be intercepted by third parties.

Screen lock

The screen lock in WhatsApp adds a layer of protection by requiring authentication, such as a PIN, fingerprint, or facial recognition, to access the app. This feature effectively prevents unauthorised access to messages and data stored in the app.

Private notifications

With this option, users can hide the content of messages in device notifications. While notifications will still appear, the message content and sender’s identity remain hidden from bystanders.

What security issues does WhatsApp have?

Despite its popularity and implemented security measures, WhatsApp has several issues concerning user privacy. Here are the key points to consider when using this messenger.

Malware

One of the main threats is attacks using malware, which most often affect users of WhatsApp’s web and desktop versions. The App Store and Google Play Store usually enforce strict security measures for mobile apps, pushing hackers to seek other methods. However, in 2019, spyware was successfully introduced into WhatsApp client applications designed for Android, Windows Phone, and Tizen, demonstrating that security measures are not infallible.

Backup vulnerabilities

WhatsApp’s backup feature allows you to restore deleted messages via Google Drive or iCloud. Unfortunately, the data stored in these services is not encrypted, which opens the door for hackers and fraudsters who can intercept the information. This is a significant security loophole that requires attention.

Privacy concerns

WhatsApp, being part of Meta—the company that also owns Facebook and Instagram—raises legitimate concerns among users about the protection of their personal data. In 2021, WhatsApp’s privacy policy was changed, allowing for greater sharing of user data with the parent company. This only strengthened the app’s ties with Meta, known for extensive data utilisation for commercial purposes. Considering that WhatsApp is a free service, some users speculate that monetising user data plays a significant role, raising concerns that the protection of privacy and confidential data might not be the company’s highest priority.

Phishing scams

WhatsApp, like other messengers, is often used as a tool for conducting phishing attacks. Such scams involve sending links to potential victims, which, when opened, can infect the device with malware. Criminals typically impersonate trusted individuals, such as friends or family members, and sometimes even take over their accounts to increase credibility. Clicking such a link leads to a connection with a server that installs malware on the victim’s device.

WhatsApp status privacy

Similar to Instagram Stories, the WhatsApp Status feature allows you to share moments from daily life that disappear after 24 hours. However, if you don’t restrict the visibility of your status exclusively to friends, anyone can access it. This increases the risk of scammers who may use the shared information to impersonate friends or engage in harassment.

Is Sending private photos via WhatsApp safe?

If you have concerns about sending private photos and don’t want them to fall into the wrong hands, it’s worth knowing. The encryption used by WhatsApp ensures that message content, including photos, is accessible only to the intended recipient. Even WhatsApp itself cannot access the photos being sent.

To further enhance the protection of private photos, you can use the ‘view once’ media feature. This allows the recipient to view the photo only once, after which it is automatically deleted. In the latest versions of the app, recipients are also unable to take screenshots of such photos or messages before they disappear.

Although WhatsApp offers solid security measures, it’s always advisable to carefully consider sending sensitive photos. There is always a risk that the recipient may not be as trustworthy as assumed. One of the potential threats is the possibility of photos being used in acts of revenge, such as revenge pornography.

How to use WhatsApp safely?

To effectively protect your WhatsApp account from potential threats, it’s worth taking the following steps.

Regularly update the app

Regularly updating the WhatsApp app is fundamental for maintaining security. New versions include bug fixes and security updates that protect against the latest threats. Enabling automatic updates is the simplest way to always use the most recent version of the app.

Use strong passwords

Even with WhatsApp’s advanced encryption, the security of your messages largely depends on the strength of your password. Avoid short or easily guessable passwords. Instead, create long, complex combinations containing letters, numbers, and symbols. An ideal password should be at least 10 characters long and difficult to crack.

Monitor connected devices

Regularly check the list of devices logged into your WhatsApp account. Ensure that only trusted devices have access. If you detect unauthorised access, immediately log out the suspicious device.

Enable two-factor authentication (2FA)

To enhance account security, activate 2FA in WhatsApp settings. This means that when setting up on a new device, an additional PIN or password will be required. This extra safeguard effectively hinders unauthorised individuals from accessing your account.

Use TuxlerVPN

A Virtual Private Network (VPN) encrypts your internet traffic, providing anonymity and protection against online threats. TuxlerVPN not only safeguards your communication on WhatsApp but also all your internet activity. A VPN ensures an additional layer of protection for your messages and confidential data.

How can TuxlerVPN protect your privacy on WhatsApp and online?

The robust TuxlerVPN application offers a set of features aimed at protecting your sensitive data. Here are the most important ones:

• Encrypting Internet traffic. A VPN secures all internet traffic by transmitting it in encrypted form through a special ‘tunnel’ to a remote server. This makes the data unreadable to third parties, preventing interception or decryption.
• Hiding your IP address. When using a VPN, your real IP address is replaced with the address of the remote server, effectively hiding your location. This means hackers won’t be able to determine your actual whereabouts, as they will only see the IP address of the country where the server you’re using is located.
• Kill switch. In the event of a sudden VPN connection drop, the Kill Switch feature automatically blocks internet access on your device. This prevents data from being exposed during temporary lapses in protection.
• Malware protection. The VPN application offers additional protection against malicious software by blocking viruses, dangerous ads, and phishing links. This feature ensures safety while browsing the internet, eliminating the risk of accidentally running harmful code.

Is WhatsApp safe?

WhatsApp is a relatively secure messenger, but not without its issues. End-to-end encryption provides good protection for messages; however, Meta’s privacy policy and susceptibility to phishing messages present significant challenges. To use the app safely, it’s advisable to implement additional safeguards, such as two-factor authentication or using TuxlerVPN. Ultimately, how safe WhatsApp is largely depends on the user’s awareness and actions.
