Deceptive Delight: A New Method to Jailbreak AI Models Unveiled
Cybersecurity researchers have uncovered ‘Deceptive Delight’, a technique to jailbreak AI models by subtly integrating harmful instructions into conversations. This method achieves a 64.6% success rate, highlighting significant security vulnerabilities in AI.
Key takeaways:
🚨 Technique Discovered: Researchers introduced “Deceptive Delight,” a method for jailbreaking large language models (LLMs) by embedding malicious instructions within seemingly benign conversation turns.
📊 Success Rate: This approach boasts an average attack success rate (ASR) of 64.6% within three interaction turns, indicating its effectiveness in bypassing AI safety measures.
🛡️ Risk Mitigation: Recommendations include robust content filtering, prompt engineering to fortify LLMs, and clearly defining acceptable inputs and outputs to counter this threat.
🔍 Research Insights: The method was tested across eight AI models with various unsafe topics, showing an increase in harmfulness and quality of outputs with additional conversation turns.
☠️ Broader Implications: The findings underscore the need for continuous improvement in AI safety protocols to prevent misuse through such deceptive techniques.
Caution Advised: LinkedIn’s hashtag#OpenToWork Becomes a Magnet for Cyber Scams
Thinking of using hashtag#OpenToWork on LinkedIn? Be wary! Cybercriminals are exploiting job seekers with sophisticated bots and spear-phishing attacks, aiming to steal personal info or scam you.
Key takeaways:
🚨 Warning Alert: The hashtag#OpenToWork hashtag on LinkedIn has become a hotspot for scammers who create fake profiles to target job seekers, often leading to phishing attempts or fraudulent job offers.
🤖 Bot Characteristics: These bots often use real people’s photos, AI-generated images, or stock photos, coupled with vague job descriptions and a sense of urgency to trick users into providing personal or financial information.
📧 Spear-Phishing Tactics: Scammers send personalized messages or job offers, which might include a link to a phishing site designed to steal login credentials or install malware, cleverly disguised as legitimate job applications or interviews.
🔍 How to Spot Them: Look for profiles with incomplete information, suspicious activity patterns, or connections that don’t match the job field. Also, be cautious with unsolicited job offers or requests for personal information.
🛡️ Protection Tips: Always verify the legitimacy of job offers, use LinkedIn’s reporting features for suspicious accounts, and enhance your privacy settings. Remember, if a job offer seems too good to be true, it probably is.
Hardcoded AWS and Azure Authentication Keys in Popular Mobile Apps
Millions of Android and iOS users are at risk due to hardcoded AWS and Azure credentials in popular apps, exposing user data and source code to potential breaches. Developers must secure these credentials to prevent unauthorized access and data manipulation.
Key takeaways:
🔐 Hardcoded Credentials: Many popular apps like Pic Stitch, Crumbl, and others have hardcoded, unencrypted AWS and Azure keys, posing a significant security risk.
📱 Affected Platforms: Both Android and iOS apps are guilty of this security oversight, with millions of downloads indicating widespread exposure.
🚨 Security Risks: These credentials could allow hackers to manipulate or exfiltrate data, leading to severe security breaches for users and businesses alike.
🔒 Developer Action Required: Immediate action from app developers is needed to remove hardcoded credentials and adopt secure practices like runtime key retrieval.
Gophish Framework Exploited for Real Phishing Attacks
An unknown threat actor is using the open-source phishing toolkit Gophish to impersonate Microsoft, targeting users with fake alerts.
Key takeaways:
🚨 Alert: Phishers are exploiting the open-source Gophish framework to craft convincing phishing emails, mimicking Microsoft’s branding and communication style.
🎯 Infection Chain: The campaign involves modular infection chains that are either Maldoc or HTML-based infections and require the victim’s intervention to trigger the infection chain.
💻 Targeted Tactics: The attackers focus on creating urgency with fake account suspension notifications, pushing users to act quickly without thinking.
🔍 Detection Difficulty: These phishing emails are designed to look legitimate, making them hard to detect without careful scrutiny or advanced security measures.
🛡️ Recommendations: Users are advised to verify the source of any urgent or threat-related emails directly through official channels before taking any action.

Personal Notes
🤔 Another week down, and it’s nearly Halloween!
This week, the team and I have been exploring new cyber threat intelligence tools. We took a deep dive into the world of OpenCTI and assessed the platform’s strengths and weaknesses compared to MISP.
It’s certainly a very well-built platform that we look forward to making content on in the future!
We also have other tools on our list, like YETI and SpiderFoot. I highly recommend everyone explore the open-source CTI tools out there and how their organization could benefit from their use.
As always, have a fantastic weekend and do something you enjoy, whether touching grass, playing video games, or learning all the things cyber (check out the learning resources included for the last one).
