Bots Get Identified

There are many cybersecurity threats that businesses have to be aware of in 2024. Whether it’s phishing, malware, ransomware, or social engineering, the methods of cybercriminals have evolved and modernised, to the point where even cybersecurity precautions from ten years ago have become largely obsolete. 

One of the most crucial areas that has developed exponentially in recent years is API abuse – specifically, utilising bots to exploit vulnerabilities in APIs, manipulate data, or launch various forms of malicious attacks. In order to gain bot protection, it has become crucial to implement modern solutions where every request – whether that’s to a website, a mobile app, or an API – is analysed and dealt with. But how exactly is this done?


Rate Limiting

There are many ways in which this can be achieved. When it comes to a traffic bot – bots that are used to generate artificial traffic to a website – rate limiting has become one of the most prevalent precautions amongst businesses. This involves monitoring the number of requests coming from a single IP address over a specified time frame, and working to classify this behaviour as potentially bot-driven. For example, if an IP address tries to access a page more than one hundred times in a minute, the site can temporarily block that address, or require the user to solve a more advanced CAPTCHA before granting further access.


Challenge-Response Tests

Speaking of CAPTCHA, this is a common precaution that has evolved in recent years. You will likely be familiar with traditional CAPTCHAs, whereby users are asked to select images based on certain criteria, or complete question-based tasks. But over the last few years, modern CAPTCHAs have been leveraged to catch out more advanced bots – ones capable of mimicking human behaviour and bypassing traditional CAPTCHA systems. A good example of this is ‘reCAPTCHA’, which uses a risk analysis engine to assess user behaviour and determine quickly whether they are human – without putting them through a text, image, or question-based test.


Judging Behaviour

This is known as behavioural analysis. While bots have been modernised and optimised maliciously in recent years, they still simulate linear or mechanical patterns – so while a human might pause or hesitate before clicking on a link, a bot will move directly to the target with minimal variation. By tracking mouse movements, keystroke dynamics, and navigation patterns, however, web applications can employ algorithms that analyse human patterns and flag any suspicious behaviour indicative of bot activity. 


ML and AI

Machine learning and artificial intelligence technologies are being progressively used more by cyber criminals, so in order to fight them, cybersecurity organisations must apply their own AI initiatives. ML algorithms, of course, can be trained using historical data to identify patterns that separate human users from bots. By feeding these models a combination of known bot behaviour and legitimate user behaviour, they can then learn to predict the likelihood of future requests – and, what's more, they can learn to detect any updates or changes in the bots themselves, adjusting the identification criteria in real-time to allow for more robust and resilient detection.


Reporting Feedback

Another way in which bots are identified is through allowing actual users to give feedback. Especially through forums, blogs, or social media platforms, users are now encouraged to report suspicious activity – such as spam comments or rapid-fire submissions – and subsequently open investigations into potential bot activity. While advanced cybersecurity solutions will always be the most effective strategy, it’s important to remember that users, too, can play a crucial role in the mitigation of bot activity. Through keeping them up to date with the latest security trends, crowdsourcing intelligence, monitoring activity in real-time, and building community engagement, it's possible to get more users invested in the security of their online environment, and ultimately formulate a first line of defence.


Conclusion

These are just a few ways in which bots get identified in 2024, as the landscape of cybersecurity continues to evolve, it’s likely that we will see even more solutions being implemented across organisations. One promising area, for instance, is the use of distributed ledger technology. Gaining traction in the cybersecurity landscape, this technology can provide transparent and immutable records of user actions that help to verify their authenticity, making it much harder for bots to impersonate legitimate users and evade detection. 

For now, however, it’s crucial that every business does as much as it can to update their bot management system and ensure they are not caught out. This isn’t just about protecting sensitive data or preventing financial loss, of course, it’s about maintaining customer trust and safeguarding brand reputation. If a system breach is caused by bot-driven attacks – and it's discovered a business did not adopt a proactive approach –  the reputational damage can easily be too great to recover from. With this in mind, every bot must be taken seriously, recognised, and dealt with before they can make such a devastating impact.
