Emojis are now the widely understood language of our digital world.These tiny icons that add color and life to our messages are designed to enhance online interactions by letting us express emotions and thoughts in an easy way. But hackers are seeing them as an opportunity to infect devices and exploit our personal data.

Here are some of the ways hackers can hijack your devices using emojis:

1. Emoji spoofing

Hackers can trick users into clicking on an emoji which will redirect them to malicious websites or initiate unwanted downloads. This technique capitalizes on the modest popularity of emoji domain names and a user’s inclination to click without thinking twice. You might fall prey to an emoji spoofing attack if you don’t question the reliability or authenticity of a website or link.

How to avoid

Every time you click on an emoji domain, irrespective of the medium, make sure the sender is someone you know or the source is trustworthy. An emoji domain is easy to spoof due to the number of visually similar emojis and skin tone modification options, so take care when entering an emoji URL. Be patient as you evaluate links of any kind to avoid making a hasty and regrettable decision.

2. Social engineering using emojis

Hackers have figured out how to use the emotional appeal of emojis as an effective tool for social engineering. By leveraging familiar emojis in messages or on social media, cybercriminals can create a sense of trust and familiarity, convincing users to share sensitive information or click on malicious links.

How to avoid

Do not trust anything or anybody on the internet. Flashy emojis or click-bait might tempt you, but if an offer or message sounds too good to be true, it likely is. Software should never be downloaded or installed from a source you don’t fully trust. Further, you should never execute a program that is supplied to you in an email from someone you don’t know, and never open an attachment. For brownie points, ensure your machine has an installed and activated Trojan antivirus program.

3. Malicious emojis

Emojis can be used to conceal malicious code or links. Hackers can generate seemingly normal emojis that, when clicked or interacted with, can result in malware downloads, phishing assaults, or unauthorized access to personal information by altering the unicode representation or employing invisible characters. Third-party emoji keyboards have long been known to be vectors of malware, as was the case with this popular Android keyboard app that blindsided users with purchases made by hidden code.

How to avoid

Carefully vet emoji keyboards and ensure they come from a trusted developer before installing. Use antivirus software and ensure your browser is up to date, which will be a critical line of defense if you come across unsafe apps or websites with malicious emojis.

4. Exploit kits based on emojis

Exploit kits are tools used by hackers to identify vulnerabilities in software and launch attacks. Researchers have developed exploit kits that use emojis as triggers to exploit vulnerabilities in popular messaging apps or operating systems. While only a proof of concept, an emoji-based exploit kit shows what is possible in the realm of modern hacking.

How to avoid

Update your browsers and plugins to their most recent fixes, and utilize browser exploit prevention technologies to guard against new vulnerabilities and stop malware from trying to enter your system through your browser. A web filter can be used to block websites that host exploit kits and obstruct malware downloads.

The use of emojis as a tool for infecting devices highlights the ever-evolving tactics employed by hackers in their quest for unauthorized access and data theft. This ostensibly innocent method of communication can be used to hide dangerous code and trick unwary users, and it is crucial for people and organizations to stay alert and knowledgeable about the hazards that can lurk behind these simple icons. You can lessen the potential harm of digital traps by maintaining awareness of the dangers linked with emojis and implementing best practices for online security, such as keeping software updated and exercising caution when dealing with unknown messages or links. When it comes to staying safe from hackers, continued learning and conscious internet behavior can make all the difference.
