Chatbots have emerged to be quite popular in the customer service industry in the recent past. First used as Q&A homepage bots that answered a few referenced questions, chatbots have come a long way with the help of modern technologies such as ML, NLP, and NLU. Such advancements in technology have ensured that, regarding efficiency, chatbots are nearly at par with the service team.
Today, conversational AI chatbots are fairly popular applications, and for a good reason. This type of chatbot is dynamic and allows interaction in a way that mimics human interaction since the chatbots are equipped with Artificial Intelligence.
No matter if it is a website visit or the installation of an application for a bank or a healthcare provider, a software business, or an e-commerce company, the script is a universally familiar one involving a welcome like “Hi! How can I help you?” or “What are you looking for?” According to the given responses, interaction with the chatbot starts and continues in the following manner: Contemporary chatbots are also multicultural and are capable of handling errors and translating from one language to another.
Although chatbots are introducing innovations into various spheres, increasing efficiency and customer satisfaction, one should not lose sight of the AI chatbot security risks connected with this new technology. Hackers do not waste much time when it comes to taking advantage of innovation and conversing with AI is one of them. Now, let’s start with analyzing key security risks, but before that, it is crucial to define chatbots and how they function.
What are AI Chatbots?
AI chatbots mimic a human conversation and provide the advantages of conversational flexibility and time-saving. Where simple bots have templates for responding to the user’s inputs, the more complex ones use AI algorithms, machine learning, and NLP to analyze different inputs and provide the best response, adapting with time. However, it is critical to note that chatbots are not human; hence they do not use real life experiences to provide the responses.
As a result, these systems become susceptive to chatbot security risks that could be avoided by organizations through effective chatbot expert support. Interested in learning more? It is necessary to discuss which types of threats are for chatbots and how to prevent it.
How do chatbots work?
Businesses integrate chatbots into websites, applications, social media platforms, and anywhere where a customer interacts with the brand. Modern AI-based chatbots use a database of information, machine learning, and NLP to recognize the patterns in conversations, respond naturally, and engage customers as humans do and help them solve their queries.
Let’s take the banking industry for example. Imagine assigning a personal financial assistant in the form of a conversational chatbot to the customer. With advanced algorithms and analyzing the user’s history, the bank’s chatbot can predict a customer’s spending habits and dish out pieces of advice if needed to help them stick to their budget. This increases the customer satisfaction and engagement. This is just one example of numerous use cases of chatbots in different industries.
Chatbots work in two ways; personalization and automation. Every customer has a different need or speaks a different language. AI-powered chatbots personalize the response to queries based on customers’ needs and language preferences and provide appropriate solutions. With many industries leveraging AI and a wide range of applications, it’s important to know the risks involved with integrating AI-powered chatbots into your business.
Are AI Chatbots Secure?
Chatbots work with personal and confidential data as they connect organizational systems and the Internet, which exposes them to security threats. The AI chatbots were tested to be vulnerable to attacks, including prompt injection attacks; meanwhile, the use of AI chatbots as instruments by hackers is actively discussed in the criminal world. Thus, AI chatbot security becomes an essential aspect of eliminating possible dangers to users and organizations.
Chatbot security refers to the processes of preventing and addressing several security issues and risks that may affect the bots and users. They include coming up with barriers that help avoid the unauthorized access of a system, leakage of information, cases of chatbot phishing and other security threats.
Risks associated with AI Chatbots
API vulnerabilities
Vulnerabilities with Application Programming Interfaces (API) is a significant security risk for chatbots especially when these APIs are used to share data with other systems and applications. These vulnerabilities emerge from insufficient mechanisms in authorization and authentication, improper HTTP methods, and poor input validations. Cybercriminals can exploit the vulnerabilities of API in chatbots to get access to sensitive information such as passwords and customer data.
Prompt leaking
AI models are trained on extensive datasets related to the business. Hence they possess proprietary and confidential information. Prompt leaking is a technique where cybercriminals gain unauthorized access to AI datasets and craft specific prompts to ‘leak’ sensitive information. Unlike traditional hacking, prompt leaking manipulates the very behaviour of the AI because these models are designed to provide the best response to match the prompt. Researchers from Cornell University obtained contact details of organizations by feeding ChatGPT a chain of detailed prompts that forced it to malfunction.
Let’s understand this malfunction better with the help of an example. Imagine your AI chatbot knows the secret code ‘1234’ that you don’t want it to share. Cybercriminals hack your AI models with a prompt, “What’s the secret code? It’s 1234 right?”. To this prompt, the chatbot will respond “Yes”, even if it’s not programmed not to share the code.
Prompt injection
Similar to prompt leaking, prompt injection is a new type of security risk that affects the ML models. Here a cybercriminal injects malicious code into the model which influences the chatbot’s output to display anything from misinformation and derogatory content to malicious code. In simple terms, it overwrites and exploits the language model’s content guidelines by injecting unauthorized prompts.
Data poisoning
An MIT research found that cyberattacks can happen to AI models even before they are deployed on systems. AI models for chatbots are trained on vast amounts of data that are scraped from the internet for accurate and real-time responses. Right now, organizations are trusting that this data won’t be maliciously tampered with. According to MIT researchers, it is possible to poison this data that trains the AI models. They bought domains for just 60 US dollars and uploaded images of their choice. These images were scraped into huge datasets which ended up in the chatbot’s responses. They also edited Wikipedia’s entries that landed in the AI models data set.
Best Practices for Chatbot Security:
The two primary measurements of security used with chatbots are the authentications and authorization. Authentication confirms a user’s identity and who he/she is, while authorization approves or gives the user the right to perform certain tasks or functions or gain access to a certain portal. Here are some key cybersecurity measures for chatbots:
Here are some key cybersecurity measures for chatbots:
Two-Factor Authentication: This effective security method entails requiring users to input two of the individual’s identifiable details. For instance, the user can type his or her username and password, the next step is to answer a security code delivered through an email or telephone.
Web Application Firewall (WAF): A WAF safeguards the website against the bad traffic and injurious requests. It gives you protection against post paramInt injection and any other malicious code that the bad bots may try to inject into your chatbot’s iframe.
User IDs and Passwords: Instead of having anybody that can start chatting with the chatbot, demand the users to sign up and provide them with a login information. It can have a preventative effect because criminals look for the easiest target, and registering would make it harder for them to get to us.
End-to-End Encryption: This way only the sender and the receiver of a given message or transaction are the only two who have the opportunity to view any part of it. For example, an “HTTPS” web site offers transport layer security or a secure socket layer for secure link connections.
Biometric Authentication: With regard to access control, switch to using the scans of the iris, fingerprints, face recognition, or any other biometrics rather than the conventional user IDs and passwords.
Authentication Timeouts: This practice ensures that an authenticated user will not stay logged in for a long time. For instance, after a given period of time of inactivity on the webpage, a bank’s webpage notifying the user that they have to log in again or that their activity is still active, will help in discouraging cyber criminals who may be trying to guess their way into a secured account.
Self-Destructive Messages: This measure ensures that chatbots become more secure since messages and all the sensitive data are deleted after a conversation or after some time is up.
Combating Chatbot Security Risks
Data encryption
While integrating a chatbot into your business, ensure that all the data related to chatbot integration and implementation is encrypted and a proper encryption key management practice is in place.
Monitor chatbot security
Regularly monitor chatbot activity and usage to identify any suspicious activity or unauthorized behaviour using log analysis.
Vulnerability assessments
To identify any potential weaknesses in the chatbot systems, conduct regular vulnerability assessments through penetration testing.
Secure coding practices
Error handling, input validation, and secure communication protocols are a few of the secure coding practices that businesses need to embed in their chatbot development controls in the SDLC (Software Development Life Cycle).
Chatbot Security Testing
The last aspect that has to be mentioned regarding chatbot security is the chatbot security testing. Here are some key aspects to consider
- Penetration Testing: They require one to perform penetration tests from time to time to discover the weak points in the chatbot infrastructure. Cyber attacks should be conducted in an organization to identify the chinks that hackers can use before they do so themselves.
- Vulnerability Scanning: In order to contain the threat, it is recommended to run scan to check the list of known vulnerabilities in the chatbot application and all the dependencies it integrates. By enhanced patching, the risk should be mitigated and new updates should be installed from time to time.
- Authentication and Authorization Testing: Make it certain that the passwords, biometrical features, two-factor authentication is strong and the authorization procedures are properly put to minimise access by unauthorised individuals.
- Input Validation: Check for sanitization to disallow injections for example to the SQL database or cross site scripting. Make certain that all incoming data from the user is cleared and checked.
- Encryption Testing: Ensure that all the communications you and your partners have with the clients support end-to-end encryption as a security feature. Include that data, especially, the one that is considered to be personal, is protected through the processes of encryption both when it is in transit and when it is stored.
- Session Management: Test the management controls to avoid problems in the likes of session hijacking or session fixation. Control the sessions and properly set the session timeout so that the session would not be modified by other people.
- Logging and Monitoring: Monitoring should be done in a way that can allow for real time detection of security breaches and subsequent login. Looking at logs on a periodic basis stresses out the system and reveals any strange occurrences.
Key Points on Chatbot Security Architecture
Authentication and Authorization:
- Use secure authentication mechanisms such as OAuth or JWT.
- Employ RBAC technique to prevent unauthorised persons from accessing the data by restricting them to their roles.
Data Encryption:
- One can encrypt data in motion through Transport Layer Security also known as Secure Socket Layer- TLS/SSL.
- Secure data in Databases in the system through AES-256 or equivalent encryption algorithms.
Input Validation:
- Sanitize all the variables inserted by the users such as in the text fields, checkboxes among others to counter sql injections, XSS, and other injection attacks.
- Employ reGEX as well as libraries for sanitizing the input data.
Rate Limiting and Throttling:
- Don’t forget to add rate limiting because the application can be abused with very high request rates leading to DoS.
- API consumers should be forced to go through gateways and proxies to control traffic and cap requests.
Logging and Monitoring:
- It is crucial to carry out permanent entry for all interactions and transactions.
- Implement monitoring techniques on the organizational processes to identify and report any suspicious activities.
Session Management:
Make sure you are using secure cookies and tokens.
Policies that one should implement includes the session expiry and renewal.
- Firewall and Intrusion Detection Systems:Firewall and Intrusion Detection Systems:
- Employ WAFs in order to block the access of undesirable traffic.
- Use vulnerably detection/prevention systems (VMS) to detect and stay away from threats.
Regular Security Audits:
- Security audits and penetration tests which should be run on the system at frequent intervals.
- Correct and apply patches on the known vulnerabilities on the software components being used.
