Cybercrime, whilst residing in the shadows, is big business. Hierarchies and roles exist. The criminals are organised – we need to be more organised. Initial Access Brokers (IABs) are emerging as a significant risk to SMEs that are unprepared. They are basically Cybercrime Middlemen, ready to steal your data to sell it on. They are playing the long game, except none of this is a game but is rather a significant threat to organisations.
What is an Initial Access Broker (IAB)?
An Initial Access Broker is a cybercriminal who specialises in gaining unauthorised access to a network or system. Once they have successfully infiltrated a network, they don’t use this access for their own ends. Instead, they sell this access to other cybercriminals. By buying access from an IAB, other malicious actors, such as ransomware gangs or data thieves, can quickly get into a network without having to break in themselves.
How do IABs operate?
IABs employ various techniques to gain access to networks:
- Phishing attacks: they send fraudulent emails that trick employees into revealing their login credentials.
- Exploiting vulnerabilities: they take advantage of unpatched software vulnerabilities to breach systems.
- Buying credentials: they purchase stolen login credentials from other cybercriminals.
Once they have access, they may create backdoors into your system (bypassing normal authentication processes), steal passwords, or gather other crucial information to make the access more valuable when they sell it.
Why could your SME be a target?
Small and medium-sized enterprises are often seen as easier targets by IABs. This is because SMEs may not have the same level of cybersecurity defences as larger organisations. However, SMEs often have valuable data and can be a steppingstone to larger attacks, especially if they are part of a supply chain involving bigger companies.
Protecting your SME from IABs
Most SMEs will be part of a supply chain and you do not want to be the weakest link. Understanding the threat posed by IABs is important in the protection of your business, your customers’ data, your reputation, and ultimately the continuation of your organisation. Here are some practical steps that you can take to safeguard your network:
- Employee training and awareness
One of the most common ways IABs gain access is through phishing attacks. Ensure that all employees are trained to recognise suspicious emails and avoid clicking on unknown links or downloading unexpected attachments.
- Regular software updates
Cybercriminals often exploit vulnerabilities in outdated software. Regularly update all software, including operating systems, applications, and security programs, to the latest versions.
- Use strong, unique passwords
Encourage the use of strong, unique passwords for all accounts. Implement multi-factor authentication (MFA) wherever possible to add an extra layer of security.
- Network segmentation
Divide your network into segments so that if one part is compromised, the attacker doesn’t get access to the entire network. This limits the potential damage and access IABs can gain.
- Regular security audits
Conduct regular security audits and vulnerability assessments to identify and address potential weaknesses in your network.
- Backup critical data
Regularly backup critical data and ensure these backups are stored securely and separately from your main network. This can help you recover quickly in the event of an attack.
- Invest in cybersecurity solutions
Ensure you are using layers of the latest cybersecurity solutions to cover all your systems and devices, wherever you are working.
- Incident response plan
Have a clear incident response plan in place. This should outline the steps to be taken in the event of a cyberattack, including how to contain the breach, assess the damage, and restore normal operations.
Conclusion
Initial Access Brokers are yet another cyber threat to business and we all need to be prepared for them. Make sure your organisation is constantly taking proactive cybersecurity steps to limit the risk of attack, helping to protect yourselves and everyone you deal with. Prepare your systems and your staff to ensure cybercriminals will find you too difficult to deal with – don’t give them an easy ride. Not sure what you need to do, or concerned that you’re not doing enough – get in touch. We constantly strive to stay ahead of the hackers and will help you to do the same.
