Programs known as spyware and stalkerware can silently infiltrate phones, computers, and tablets, steal personal data, monitor user activity, and even activate cameras and microphones without consent. Therefore, parents are advised to pay attention to the following symptoms.
Is the device behaving differently? Some spyware programs modify permissions to collect more information. In turn, since these programs often appear legitimate, users, including children, may install them without being aware of the risk. If an unknown application is found, it is recommended to perform an analysis with reliable security software, delete the application, or consult an expert to examine the device.
Malicious programs often run silently in the background, which can quickly drain the battery, cause the phone to heat up even when idle, or cause data usage spikes without apparent reason. This type of software has been linked to cases of domestic violence, controlling relationships, harassment, or even pranks among peers.
On the other hand, stalkerware is used to monitor a known person. Some advanced versions can activate cameras or microphones without the user's knowledge, allowing attackers to observe and listen remotely. Manually checking application permissions can reveal this behavior.
If a device has been compromised, here are some basic steps for recovery: install a reliable antivirus, keep it updated, disconnect the device from the internet to prevent remote access, perform a full system scan, delete the detected malicious software, and change all passwords for associated accounts.
Spyware infections can occur in many ways: by clicking on malicious links, opening attachments in phishing emails, or downloading seemingly harmless applications that hide spying functions. Stalkerware is usually installed manually by someone with physical access to the device.
Families can adopt simple but effective measures to reduce risks, such as covering the webcam when not in use, teaching children to lock their devices, using strong passwords, and enabling multi-factor authentication. Technological tools can be allies if used with a clear purpose, transparency, and respect.
In some cases, it may be necessary to seek assistance from a cybersecurity professional.
Are system settings changing on their own? Unlike a real game, the fake application had no interface and, when launched, requested access to notifications. Although such files disappear quickly, security programs can detect them.
It can hide under the name and icon of another application, run in the background, and monitor online behavior, location, and device activity. In a context where webcams, online games, and virtual classes are part of the daily lives of children and adolescents, the increased use of spyware and stalkerware can put their privacy and security at risk.
They also request very broad permissions, such as access to the camera, microphone, or location, even if it is not related to their function.
The purpose of spyware is to steal confidential information, such as passwords, banking data, or browsing history, which is then sold or used by cybercriminals.
Both spyware and stalkerware have similar capabilities, although their purposes are different.
If the webcam light flashes or turns on when you are not using it, this is considered a warning sign.
Are there unrecognized applications appearing? Once granted, Ratel could intercept text messages and hide notifications from applications to prevent the victim from discovering that their money was being used to pay for new subscriptions.
On computers, unexplained mouse movements or applications that suddenly crash may also be reported, which is another sign of unwanted software running in the background.
Beyond technical solutions, prevention begins with digital education. These habits strengthen daily security and reduce the chances of suffering attacks or intrusions, but when it comes to caring for a child or adolescent, it is key to promote trust and constant dialogue.
In 2024, for example, a Telegram channel was discovered distributing the spyware Ratel, disguised as the popular clicker game Hamster Kombat.
These tools often hide under names like System Service or Device Manager.
If the GPS location reactivates constantly or privacy settings seem to change, it is a warning sign.
Although it is often presented as a security or family tracking tool, it actually allows for total control of the device without the victim's consent.
Are these characteristics a sign of infection? Some spying tools take screenshots or photos and store them briefly before sending them to attackers.
