Statista data shows that about 3 billion people actively use WhatsApp for personal and business engagements. Hacking incidents like Israel’s NSO Group and Russia’s Star Blizzard made headlines recently. These WhatsApp hacking incidents and many more are recorded daily globally. Luckily, Blockchain technology can change this pattern by introducing new security trends.

It stores chats on a decentralized network and verifies through cryptographic keys. Users control their encryption keys, which reduces hacking, leaks, and spying. This technology could be a solution to stop the millions of hacking incidents affecting WhatsApp users.

What does WhatsApp hacked and blockchain mean?

The term “WhatsApp hacked” is used to describe a situation in which third parties access your account without permission. This illegal access compromises your messages, communication, and stored files. Hackers may use strategies like spyware, phishing, and account takeovers. Blockchain is a ledger technology that stores your data in distributed locations. This strategy increases your data security and increases system transparency.

WhatsApp hacking is a serious problem affecting nearly all social media channel users. Today, many users have come across the phrase hacker WhatsApp, common in online crime. Your main focus should be to learn how to block someone on WhatsApp and prevent hacking. The best tips to follow include learning how to log out of WhatsApp after a compromise. Sign in to your account through multifactor authentication, update your apps often and use Moonlock cybersecurity software. Never open attachments or links without confirming their sources to prevent phishing and malware installation.

Is WhatsApp safe from hackers?

You may want to learn about WhatsApp security issues to understand whether it is safe from hackers. The first question you may ask is: “Is WhatsApp encrypted”? This app sends encrypted messages, but you have to go deeper into its security issues. Here are the problems you need to know:

• All chats from over 3 billion users are stored in a centralized server. This makes everyone’s messages vulnerable to hacking.
• Every account is connected to a specific phone number. This security arrangement is vulnerable to SIM swapping.
• The company collects data from users, such as your contacts, types of chats, active time, etc.
• Users often receive phishing links, and many of them become victims.
• Devices often get lost, and those who find them easily access accounts.
• Users may opt to allow cloud-based backups for easier recovery. Unfortunately, data stored in the cloud is never encrypted. 

Considering these setbacks, your account can be hacked if it lacks security walls. The next issue requiring your attention is understanding how to check WhatsApp hack.

Ways blockchain can improve WhatsApp security

Blockchain is an emerging technology that is changing online security in many business sectors. The company and the app developers can agree to switch from a single server approach and adopt a decentralized system. Once adopted, blockchain could change security in many ways like:

• Blockchain allows the use of smart contracts, which improves user privacy. These programs are self-executing, giving users enhanced benefits. Account holders may delete conversations.
• Customers can no longer depend on a centralized storage that limits their security. They begin to enjoy a decentralized system.
• Messages are stored as long as the user wants to keep them. No one can change chats or delete them.

How to check WhatsApp hack

You may suspect hacking if your app is logged out often or requires verification unexpectedly. You may experience quick data drain because of malware or spyware attacks. You could receive many unexpected messages from unusual people. The messages could also come from your contacts, but you may notice they are unusual. You may see one or more unfamiliar devices connected to your device.

Log them out by opening the three dots on the top left of your device. Open the Menu and scroll down to connected devices and disconnect them. Log out of your account and disable the internet connection. Reinstall the app, change your pin, and activate multifactor authentication.

Possible changes that blockchain would introduce 

Blockchain has many advantages over the current security architecture on WhatsApp. The new design could introduce various changes and advantages as follows:

• The design would eliminate the need for users to create accounts linked to their telephone numbers. It would allow them to create accounts on browsers, wallets, etc.
• Instead of using one encryption method, the new design would encrypt every chat individually. It would generate a unique key for the message and send it through the user’s distributed network.
• Users would no longer need to send larger files like videos in multiple formats, like AVI and WMV. They can all be converted into one format, like IPFS built into the blockchain.
• Users would enjoy full message control without the company’s manipulation.
• There would be greater chat transparency, and the architecture would be harder to hack.

WhatsApp chats and their future security

Different entities seek to spy on private chats, including governments, hackers, and data companies. Blockchain offers communication solutions that could change the future of chat security. Its integration into WhatsApp would increase app stability, transparency, and security.

Users would enjoy strengthened protection against cybercrime. They would have more control over their accounts and communication. Privacy would be taken from the company’s hands and restored to the user’s hands. Most of the current WhatsApp security issues would be solved.

Setbacks of a blockchain-powered messaging system

Blockchain is an emerging technology, and many of its structures are improving year to year. Due to this, companies using this technology would have to invent ways to overcome scalability and speed limitations. The system’s storage architecture is strong but costly.

Governments could resist the migration, seeking structures they can control. Non-technical users might have challenges managing private keys. If lost, it could mean losing their accounts entirely.

Conclusion

WhatsApp uses a centralized system that makes it vulnerable to many security breaches. The system can be tampered with, spied upon, and hackers could connect strange devices to users’ devices. Blockchain could offer the solution required to change the security structures of this app. Its system is tamper-proof, and users may decide to keep messages for more years. Integrating it would improve user confidence, and its adoption would increase.
