A no-click attack, also known as “zeroclick”is a cyber threat where you do not need to click on a certain link, open a file or perform any other type of action to be affected.
It is a very sophisticated type of threat since it infiltrates your device in an invisible way. For example, you receive a harmful file via messenger or email and your device processes it automatically.
Then, the attacker takes advantage of vulnerabilities in the operating system and takes control of your mobile to run malicious programs, access personal information or spy on conversations without leaving traces of the activity, compromising your privacy and security.
Although it is very difficult to detect, if you notice unusual performance on your device or with some apps, or discover that there is a very high consumption of mobile data, it is very likely that you are being affected by a no-click attack.
How to protect yourself from a no-click attack
-Constant update: If you want to minimize any type of risk associated with a no-click attack, you have to always keep your device updated. Remember that software updates usually include patches that correct many vulnerabilities.
Therefore, it is recommended that you configure your mobile phone to automatically install the most recent updates released by the manufacturer.
-Restart your mobile: Also, restart your phone from time to time because this can help you temporarily disable any malware that has been installed on the device.
-Use official stores: It is also very important that you download applications only from official stores, such as the Google Play Store for Android or the App Store, if you use the iOS operating system.
Likewise, you should avoid installing programs that come from unknown sources as they may contain bugs that can be exploited by hackers.
-Use an antivirus: Likewise, you should consider installing a mobile antivirus. This way you can examine the behavior of your existing applications and detect possible threats in time.
-Check app permissions: As for the applications themselves, try to constantly review the permissions they have. If necessary, disable access to sensitive functions such as the microphone, camera or location, as long as these are not necessary for their correct functioning.
-Prevent automatic downloads: Likewise, in messaging or email tools, you must configure the options to prevent files or documents from downloading automatically. This reduces the possibility of a malicious program being installed without your consent.
-Use double authentication: Finally, consider using multi-factor authentication (MFA) or the same FIDO2 authentication on all accounts where they are supported.
This way, it will be much more difficult for attackers to access and use your confidential information if they manage to take over your device.
