How to Protect Against Chatbot Abuse
Generative AI chatbots are customizable entities designed to respond to our queries and perform tasks. They’re at the center of our tech progress. We stand at the threshold of a new era where the ethics surrounding AI are being still explored. Generative AI can be used for both constructive and detrimental purposes, and we’re only beginning to unravel the complex web of ethical considerations surrounding this transformative technology.
Generative Chatbots and Abuse: A Growing Concern
1. Spamming and Overloading:
According to the UK government, in the coming 18 months, generative AI will magnify current risks rather than introduce new ones. However, AI will significantly accelerate the speed and scale of certain threats and introduce some vulnerabilities.
A few users intentionally bombard generative AI chatbots with excessive and repetitive messages, leading to many negative consequences. The volume of incoming messages can trigger system overload, blocking the chatbot’s ability to process and respond effectively. This overload often results in delayed responses, reduced user satisfaction, and, in extreme cases, system crashes.
Cyber attackers may use generative chatbots like ChatGPT to flood email systems with spam, disrupting communication networks.
Examples of Threats and Vulnerabilities:
- Denial-of-Service Attacks: Cyber attackers may exploit generative AI chatbots to initiate denial-of-service attacks by flooding them with a massive volume of requests.
- Malicious Script Injection: Attackers can inject malicious scripts or code, compromising the integrity of the system.
- Privacy Violations: In instances of overloading, sensitive user information may be exposed or mishandled by the generative chatbot.
- Resource Depletion: Continuous spamming can lead to the depletion of computational resources, affecting not only the chatbot’s performance but also the overall functionality of the underlying systems.
2. Phishing and Scams:
Cybercriminals are using the conversational skill of chatbots to carry out phishing attacks. These bots mimic the language and persona of trusted entities, engaging users in seemingly genuine conversations to extract sensitive information. Beyond traditional phishing, attackers can create scenarios that play on emotions, urgency, or authority.
Examples of Cybercriminals Using Chatbots for Phishing Attacks:
Impersonation of Trusted Entities:
- Cybercriminals create chatbots that mimic the appearance and language of well-known companies or banks.
- Users receive messages from these fake chatbots, claiming urgent issues with their accounts and requesting immediate action.
Social Engineering Tactics:
- Chatbots engage users in seemingly authentic conversations, often posing as friends or colleagues.
- Users are manipulated through emotional appeals, urgency, or authority, convincing them to disclose sensitive information or click on malicious links.
Interactive Forms and Surveys:
- Chatbots present users with harmless forms or surveys, prompting them to input personal details.
- Users unknowingly provide sensitive information, thinking they are engaging in a legitimate interaction.
False Security Alerts:
- Chatbots simulate security alerts, informing users of unauthorized access or compromised accounts.
- To resolve the supposed issue, users are directed to click on links leading to phishing websites designed to collect login credentials.
Fake Product or Service Offers:
- Cybercriminals deploy chatbots as customer support for popular products or services.
- Users may receive enticing offers or promotions, but to avail them, they are asked to provide personal or financial information.
3. Offensive Content and Hate Speech:
Chatbots are used to spread hate speech, targeting individuals or groups based on their ethnicity, religion, or other identifiers. The automated nature of chatbots amplifies the reach of hate speech, contributing to the erosion of online civility. Also, some chatbots generate inappropriate or offensive responses to user queries. This poses a significant challenge for developers in curating chatbot behavior and ensuring adherence to ethical standards.
Example –The ‘Nothing, Forever‘ Incident and Twitch’s Battle Against Hate Speech
- Incident Overview: In early February, the AI experiment “Nothing, Forever” received a 14-day ban on Twitch, a prominent streaming platform.
- Nature of the AI Experiment: It is an AI-driven project presented as an endless cartoon parody of Seinfeld.
- Content Moderation Approach: The project relies on OpenAI’s GPT-3 language model for dialogue generation, incorporating minimal external content moderation.
- Triggering Event: During a standup routine within the stream, the character Larry Feinberg made inappropriate remarks about being transgender.
- Reason for Suspension: The ban was attributed to a violation of Twitch’s Community Guidelines or Terms of Service.
- Investigation Findings: Subsequent investigations suggested that the transphobic comments may have emerged due to switching GPT-3 models—from the advanced Davinci to the “less sophisticated” Curie—during technical glitches.
- Creator’s Admission: In an update, the creators admitted mistakenly believing they were using OpenAI’s content moderation tool.
4. Content Manipulation:
The manipulation of content is a critical issue in chatbot interactions. This problem highlights the potential for generating false or misleading information, which can compromise the truth. For instance, deepfakes are manipulations that distort reality, and we’re seeing a similar risk in how chatbots can be used to create misleading content. In video deepfakes, facial expressions, gestures, and even voice patterns are manipulated to make it appear like someone is doing or saying something they never did. This technology has raised significant concerns due to its potential for malicious use, such as spreading misinformation, impersonation, and manipulating public opinion.
