Bot problem? The malicious bots are scraping your site, stealing your content, and overwhelming your servers. You have tried blocking IP addresses, but the bots switch IP addresses faster than you can block them.
You have tried CAPTCHAs, but the bots are beating the CAPTCHA challenge before humans even see it. You have tried rate limiting, but the bots divide their attacks among thousands of IP addresses.
The bots are winning.
But what if you could use bots to fight bots? What if you could release automated intelligent systems that seek out and destroy the malicious bots automatically?
This is what the AI hunter killer does for you. Autonomous bots that seek out other bots.
Allow me to explain how, why, and how you can use them.
What Is an AI Hunter-Killer
An AI hunter-killer is an autonomous software agent designed that has the ability to hunt and eliminate malicious bots on its own, without any human intervention. It makes decisions independently and on the fly.
What it does:
The hunter-killer searches for bots on your network. It will use network traffic analysis to identify bots on the network. It detects the presence of bots. It discerns benign from malicious bots.
What it doesn’t do:
It doesn’t substitute for human intelligence. It doesn’t make any definitive decision regarding any vital systems. It doesn’t work in an uncontrolled manner.
The purpose:
The purpose is to design a self-healing defense system. Some malicious bots enter into your system. The hunter-killer identifies them. It nullifies them. It learns from the process. It gets better at identifying such malicious bots in the future.
How Autonomous Hunter-Killer Functions
The hunter-killer functions in four steps: detection, classification, neutralization, and learning.
Step 1: Detection
This hunter-killer monitors your network for bots. It analyzes traffic and behavior of requests per second. It detects any anomalies that could possibly be associated with bot activity.
What it looks for:
Requesting too many requests per second for an individual IP or IP range. Request patterns. Old user agents. Known botnets. Trying to access protected data.
How it detects:
The hunter-killer uses machine learning models trained on billions of requests. It knows what normal traffic looks like. It knows what bot traffic looks like. It flags anything that deviates from normal.
Step 2: Classification
Since the hunter-killer has now successfully determined that there might be a bot, the next step would be classification. It determines whether the bot poses any risk or not.
Factors that need to be considered:
Bot’s behavior. The resources it attempts to access. The rate at which it sends queries. The pattern of the queries. Origin of the queries.
Procedure for classification:
To classify the bot, the hunter-killer uses the rule-based detection technique and machine learning approach. It makes a comparison of the bot's activity with typical patterns. It assigns the bot a certain score. Then it classifies the bot according to the score.
Step 3: Neutralization
Following the classification of the bot as a malicious one, the hunter-killer neutralizes the bot by taking measures that will help neutralize it.
The neutralization techniques used are:
To block the IP address of the bot. To slow down the request made by the bot. To provide wrong information to the bot. To redirect the bot to a honey pot. To mislead the bot. For delaying the bot's response till it uses up all its resources through the bot's request to use its resources.
Selection of neutralization technique:
The hunter-killer uses the suitable neutralization technique based on the nature of the bot. For example, if a bot is scraping content, the hunter-killer will throttle it. If the bot is doing a credential stuffing attack, the hunter-killer will redirect it to a honeypot. A bot that is launching a DDoS attack might be blocked entirely.
Step 4: Learning
The hunter-killer learns after successfully neutralizing a bot. It keeps updating its models. It increases its effectiveness in recognizing similar bots.
What it learns:
Bot’s behavior. Methods used by the bot to avoid detection. Targets selected by the bot. The bot’s infrastructure.
How it learns:
Hunter-killer uses reinforcement learning. It receives rewards for successful detection and neutralization of bots and penalties for false alarms.
Why Hunter-Killers Are Effective
They operate at machine speed.
Human analysts cannot keep up with bot swarms. The hunter-killer can. It processes thousands of requests per second. It detects bots in milliseconds. It neutralizes bots in seconds.
They evolve with the times.
There are always new tactics that the attackers develop. Hunter-killer adapts itself after every encounter with the attacker. It learns how to counter new tactics.
It scales well.
One hunter-killer is able to examine millions of requests. It can also operate in different networks. It can integrate with other security measures.
They are economical.
Hunter-killer decreases the burden on human analysts. It makes the job easier for them. It allows analysts to focus on high-value threats.
They ensure self-healing of defense systems.
The hunter-killer is self-learning and constantly upgrades itself. There is no need to update it manually.
Hunter-Killer Use Cases
Use Case 1: Web Application Protection
The company deploys a hunter-killer for its web application protection. The hunter-killer inspects all the traffic coming into the web application. If the hunter-killer detects any bots which are performing any kind of attacks like scraping, brute-forcing, or launching DDoS attacks then it stops them from doing any harm.
Use Case 2: API Protection
The company employs the hunter-killer for its API protection. The hunter-killer inspects all the requests made to the API and identifies if any bots are abusing the API.
Use Case 3: E-Commerce Protection
A business operating an e-commerce site uses the hunter-killer system to protect its checkout page. The hunter-killer system watches the checkout process and finds any bots trying to add products to their cart, purchasing anything, and using stolen credit card information.
Use Case 4: Social Media Account Safety
An organization operating social media takes advantage of the hunter-killer approach in safeguarding its users' account logins. The hunter-killer approach monitors the account login process and detects any bots seeking to take over users' accounts.
Use Case 5: Ad Fraud Prevention
An online advertising network uses a hunter-killer to secure its ad placements. The hunter-killer watches for ad requests. It identifies any bots that are clicking on ads fraudulently.
Deploying the Hunter-Killer: Steps to Follow
Step 1: Define Objectives
What should your hunter-killer protect? Are there web applications, APIs, e-commerce checkouts, ad inventories that it should protect? It is time to define them.
Step 2: Data Collection
You will require data for training your hunter-killer. Collect data for normal traffic. Collect data for bot traffic. Label the data.
Step 3: Training the models.
Train your machine learning models with your dataset. In case you know about the threat, apply supervised learning; else use unsupervised learning.
Step 4: Implementation of the hunter-killer.
Deploy the hunter-killer into your network. You need to make sure that your hunter-killer fits well within other cybersecurity technologies. You also have to make sure that your hunter-killer operates according to your risk appetite.
Step 5: Monitoring and Improvement.
Monitor the performance of your hunter-killer. Note the false positives and false negatives. Retrain the models regularly.
