Common Terror Attack Methods

Terrorists use various attack methods to cause harm, fear, and disruption. Security officers must be able to identify potential threats, recognize suspicious activity, and respond effectively to prevent attacks or minimize damage.

This guide will help security officers understand the most common terrorist attack tactics, their warning signs, and how to enhance security measures to prevent them.

1. Understanding How Terrorists Plan Attacks

Before an attack takes place, terrorists go through a planning phase that involves:

🔹 Target Selection – Identifying locations with high public or symbolic value.
🔹 Surveillance – Observing security measures and identifying weaknesses.
🔹 Testing Security Measures – Attempting unauthorized access or probing for vulnerabilities.
🔹 Acquiring Equipment & Training – Collecting weapons, explosives, or cyber tools.
🔹 Rehearsing the Attack – Conducting dry runs or practicing operational tactics.

💡 Security officers who recognize these early warning signs can help prevent potential attacks.

2. Common Terror Attack Methods

Terrorists use various tactics based on their objectives, available resources, and the level of security at their target.

1️⃣ Marauding Terrorist Attacks (MTA) – Firearms & Bladed Weapons

🔹 What is it? Coordinated attacks by multiple armed terrorists, often using firearms, knives, or blunt objects.
🔹 Examples:

  • 2015 Paris attacks – Multiple gunmen and suicide bombers targeted public spaces.
  • 2019 London Bridge attack – An attacker used a knife to harm civilians.

🔹 Warning Signs:
🚩 Individuals loitering in crowded areas without clear purpose.
🚩 Unusual behavior, such as carrying large bags, concealing weapons, or wearing heavy clothing in warm weather.
🚩 Someone repeatedly checking exits or security presence.

🔹 Security Measures:
✅ Conduct random bag checks and enforce strict access control.
✅ Identify suspicious individuals and notify authorities immediately.
✅ Train security teams in active shooter response and public evacuation procedures.

2️⃣ Explosive Devices – IEDs, PBIEDs, VBIEDs

🔹 What is it? Use of improvised explosive devices (IEDs), either carried by a person, hidden in a vehicle, or placed in a crowded area.
🔹 Types of Explosives:

  • Improvised Explosive Device (IED): Hidden in bags, garbage bins, or buildings.
  • Person-Borne IED (PBIED): Suicide bombers wear explosive vests.
  • Vehicle-Borne IED (VBIED): Explosives placed in cars, trucks, or motorcycles.

🔹 Examples:

  • 2005 London Bombings – IEDs placed in backpacks exploded in trains and buses.
  • 2017 Manchester Arena Attack – PBIED used at a concert venue.

🔹 Warning Signs:
🚩 Abandoned bags, luggage, or packages left unattended.
🚩 Strong chemical smells (e.g., petrol, ammonia, or sulfur) near restricted areas.
🚩 Unusual modifications to vehicles parked in sensitive locations.

🔹 Security Measures:
✅ Conduct bag checks and vehicle searches at entry points.
✅ Use CCTV surveillance to monitor unattended objects.
✅ Train staff to recognize suspicious behavior and report threats immediately.

3️⃣ Vehicle as a Weapon (VAAW) – Vehicle Ramming Attacks

🔹 What is it? Attackers use cars, vans, or trucks to run over civilians in crowded areas.
🔹 Examples:

  • 2016 Nice, France Attack – A truck plowed through a crowd, killing 86 people.
  • 2017 Westminster Bridge Attack – A vehicle was used to ram pedestrians before a knife attack.

🔹 Warning Signs:
🚩 Vehicles parked near security barriers or restricted zones.
🚩 A driver loitering in a vehicle without clear purpose.
🚩 Cars attempting to breach security barriers or checkpoints.

🔹 Security Measures:
✅ Use bollards and barriers to restrict vehicle access to pedestrian zones.
✅ Increase security patrols near high-risk areas (e.g., crowded streets, stadiums).
✅ Train security personnel to identify and react quickly to ramming attempts.

4️⃣ Hazardous Substances – Chemical, Biological, & Radiological Attacks (CBR)

🔹 What is it? The use of toxic chemicals, biological agents, or radiation to harm large populations.
🔹 Examples:

  • 1995 Tokyo Sarin Gas Attack – Nerve gas was released in a subway station.
  • 2001 Anthrax Attacks (USA) – Biological agents were sent through the mail.

🔹 Warning Signs:
🚩 Reports of unusual odors, smoke, or gas leaks in public spaces.
🚩 Individuals wearing protective masks or unusual clothing in non-hazardous environments.
🚩 Sudden illness, vomiting, or difficulty breathing among multiple people.

🔹 Security Measures:
✅ Conduct air quality monitoring in high-risk areas.
✅ Train staff to respond to hazardous substance threats and containment procedures.
✅ Ensure proper emergency decontamination plans are in place.

5️⃣ Cyberattacks – Targeting Digital Infrastructure

🔹 What is it? Cyber terrorists attack critical infrastructure, financial systems, or government networks.
🔹 Examples:

  • Ransomware attacks on hospitals, banks, and government offices.
  • DDoS (Distributed Denial-of-Service) attacks on online services.

🔹 Warning Signs:
🚩 Unauthorized access to security systems or surveillance cameras.
🚩 Employees receiving phishing emails with suspicious links.
🚩 Unexpected network slowdowns or system failures.

🔹 Security Measures:
✅ Use strong cybersecurity protocols and firewalls.
✅ Train staff to recognize phishing attempts and suspicious emails.
✅ Regularly update security software and system passwords.

💡 These threat levels can change based on intelligence reports, global incidents, and national security assessments.

3. Security Officer Response to Terrorist Threats

Security officers must be prepared to respond to terror threats quickly and effectively.

How to React in a Terrorist Attack:

🚨 Evacuate & Secure the Area – Move people to safety and prevent access.
🚨 Call 999 Immediately – Report the location, number of attackers, and weapons used.
🚨 Do Not Engage the Attacker – Leave the response to trained law enforcement.
🚨 Follow Emergency Protocols – Alert supervisors and security teams.
🚨 Assist Authorities – Provide any CCTV footage or eyewitness reports.
