Your generosity can provide a lifeline to victims of cybercrime

The technology used for surveillance has progressed rapidly. Devices can connect to wireless networks or mobile networks, making it easier to buy and use equipment that can record audio or video, or track a person's location.

Many people – particularly in cyberstalking and online harassment cases – may feel that their homes, devices or vehicles are being monitored, or that their location is being tracked.

In some cases, there may be another explanation for how someone knows information about you. For example, they may have access to an online account, a shared location setting may be enabled, someone close to you may be passing on information, or information may be publicly available online.

However, surveillance devices and trackers can be used in stalking, harassment and abuse. Concerns should therefore be taken seriously and explored safely.

It is important not to assume that a surveillance device is present simply because someone appears to know information they should not know. There may be a simpler explanation. Consider different possibilities without dismissing your concerns.

How might someone spy on you using bugs, cameras and trackers?

There are several ways someone may listen to conversations, watch someone or track their location. These are described below at a high level.

Physical surveillance

Surveillance does not always involve technology. Someone may physically follow you or listen to your conversations.

If the person knows you well, they may already know your typical routine. They may also build a picture of your movements from information shared online.

An individual may also obtain information from someone close to you, or use a false identity online to persuade you to communicate with them or share sensitive information.

Physical surveillance can be difficult to identify. Avoid making assumptions about who may be responsible and focus on your immediate safety and the evidence available.

Hacked online accounts & devices

Unauthorised access to online accounts or devices can allow someone to monitor you.

An ex-partner or another person may know your passwords, or may have helped set up an account. If they can access an account, they may be able to see communications, personal information, location data or photographs.

A person may also have access to an account because they previously managed or paid for a service. For example, someone who manages a household internet account may have access to the router's administration settings.

Devices can also be compromised. Malicious software such as spyware may allow someone to access information from a device, including its location, camera, microphone, communications or settings.

Using the technology you have already

Think about the microphones, cameras and location-enabled devices already in your environment.

These may include:

  • mobile phones

  • tablets

  • computers

  • smart watches

  • smart TVs

  • smart speakers

  • home security systems

  • vehicle systems

A mobile phone is particularly important because it is usually carried with you.

Many devices and applications are managed through online accounts or mobile apps. If another person gains access to these accounts, they may be able to access information or change settings.

Location-sharing and device-finding services can also be misused. In some cases, another person may have had physical access to your device and enabled location sharing without your knowledge.


Planting a bug, camera or tracker

Small surveillance devices are widely available for purchase online. These can include audio recording devices, hidden cameras and location trackers.

The fact that a device is commercially available does not mean that it can lawfully be used to monitor another person. Using surveillance equipment without appropriate permission may raise legal issues depending on the circumstances, including privacy, interception, harassment, domestic violence or cybercrime concerns.

For a physical surveillance device to be placed somewhere, the person responsible would generally need some form of physical access to that location or object.

Common types include:

  1. Audio recording devices – small devices that may be designed to record or transmit conversations. Some may use mobile networks or store recordings locally.

  2. Camouflaged devices – surveillance equipment may be concealed within everyday objects such as chargers, plugs, clocks or vehicle accessories.

  3. Cameras – cameras may be standalone devices or concealed within another object. They may connect to a network or store recordings locally.

  4. Location trackers – small devices can be attached to vehicles, bags or other objects to record or transmit location information. Some store historical location data, while others may transmit location information in near real time.

You do not need to identify the exact type of device or determine how it works. The priority is to stay safe, preserve evidence and identify appropriate next steps.

Approaches to dealing with bugs, cameras and trackers

You may realise that you are being monitored because someone appears to know information they should not know, or because someone appears to know your location unexpectedly.

  1. Keep a log of incidents – Record incidents that make you concerned about surveillance.

    Where it is safe to do so, record:

    • the date and time

    • what happened

    • what information the other person appeared to know

    • who else knew the information

    • which devices or accounts were involved

    • relevant messages, emails or other communications

    • any suspicious changes to devices or accounts

    Keeping a record may help identify patterns and alternative explanations. It can also help preserve useful evidence.

  2. Prioritise safety if you are being followed – If you believe you are being physically followed or are in immediate danger:

    • do not confront the person

    • move to a safe or public location if possible

    • tell someone you trust what is happening

    • contact SAPS on 10111 in an emergency

    • if it is safe to do so, note relevant details about the incident

    SAPS advises that 10111 is for police emergencies. For less serious matters, you can contact or visit your nearest police station.

  3. Secure your online accounts and devices –Securing online accounts and devices can reduce the ability of another person to monitor you.

    Where it is safe to do so, consider:

    • changing passwords from a safe device

    • enabling multi-factor authentication

    • checking account recovery information

    • reviewing active sessions and logged-in devices

    • reviewing location-sharing settings

    • checking which apps have access to location, camera and microphone

    • updating devices and applications

    • reviewing connected devices and accounts

  4. Search for bugs, cameras and trackers – ou may choose to conduct a basic visual search of your home, vehicle or belongings.

    You can look for:

    • unfamiliar objects

    • objects that appear to have been moved or modified

    • unfamiliar chargers, plugs or electronic devices

    • unexplained wires

    • unfamiliar devices attached to a vehicle or personal belongings

    Avoid dismantling electrical equipment or placing yourself at risk while searching.

    Radio-frequency (RF) detectors are also available, but they can be difficult to use and may detect legitimate signals from your own devices or neighbouring properties. A positive reading does not necessarily mean that a surveillance device is present.

    The Cyber Helpline does not recommend a specific commercial product or claim that a particular device can reliably identify surveillance equipment.

  5. A professional bug sweep – Professional technical surveillance counter-measures (TSCM) or bug-sweeping services may be available in South Africa.

    These services can be expensive and availability varies. If you want to use one, independently verify the provider's credentials, experience and costs before proceeding.

    The Cyber Helpline does not conduct physical bug sweeps or inspect your home, vehicle or devices.


What to do if you find something

If you find a device that you believe may be a surveillance device, do not touch, dismantle or dispose of it if it is safe to leave it in place.

Where it is safe to do so, you should:

  • photograph the device in its original location

  • note where and when it was found

  • avoid handling it unnecessarily

  • consider whether removing it could alert the person responsible

  • report the matter to SAPS if you believe a crime may have occurred

SAPS can investigate reported crimes and will record a case at a police station. Keep the reference or CAS number provided for future enquiries.

If the concern relates to a compromised online account or device, preserve relevant evidence such as screenshots, emails, messages and account activity before making changes where possible.

If you do not wish to report the matter to the police, you can still take steps to secure your accounts and devices. However, be aware that removing access or changing settings may alert the person responsible and could potentially change their behaviour.

Where there are stalking, harassment, domestic violence or other safety concerns, you may benefit from specialist support before taking action.


Report the crime

In South Africa, you can report suspected criminal activity to SAPS or your nearest police station.

For an emergency or immediate danger, call 10111. SAPS also operates Crime Stop on 08600 10111 for anonymous reporting of criminal activity; Crime Stop should not be used for emergencies.

If you are experiencing stalking or harassment, you may also be able to apply for a protection order under the Protection from Harassment Act 17 of 2011. The Department of Justice states that the Act covers harassment and stalking, including cyber-stalking, and allows a person to apply for a protection order at a Magistrate's Court.

Where the person responsible is a current or former partner, family member or another person within a domestic relationship, the Domestic Violence Act may also be relevant. The Department of Justice identifies stalking as a form of domestic violence and provides information on applying for a protection order.

The Cyber Helpline cannot advise you on which legal remedy applies to your specific circumstances. You can use the available reporting and support options and obtain appropriate legal or specialist advice where necessary.
