A new cyber-attack method known as “Conversation Overflow” has recently surfaced, posing a serious threat to AI and ML security systems.
Description
This technique allows hackers to deceive security systems by sending cloaked emails, enabling phishing messages to bypass security checks and target high-level executives for credential theft. Cybercriminals craft emails with visible prompts for recipients to click links or provide information [3], while concealing text to deceive AI/ML algorithms [3]. By hiding malicious content within harmless text [1], cybercriminals can evade advanced security platforms and trick machine learning tools into accepting emails as legitimate. SlashNext threat researchers have observed threat actors using this method to deliver malicious payloads and bypass security controls in real-time, with criminal hacker groups continuously refining this toolkit.
Conclusion
The emergence of “Conversation Overflow” poses a significant threat to cybersecurity, exploiting vulnerabilities in AI and ML-driven security platforms [2]. It is crucial for organizations to enhance their security measures, stay vigilant against such attacks, and continuously update their defenses to mitigate the risks posed by this new cyber-attack method.
