Meta disclosed that hackers exploited its AI support chatbot to take over 20,225 Instagram accounts starting April 17, 2026. The attackers simply asked the chatbot to change email addresses and reset passwords, bypassing security checks. High-profile victims included Barack Obama's White House account, Sephora, and the US Space Force Chief Master Sergeant before Meta issued an emergency patch on May 29.
Recent attacks on Meta AI and ChatGPT reveal how prompt injection attacks can hijack AI systems to steal accounts and spread phishing. The Meta AI hack allowed attackers to reset Instagram passwords without authentication, including Obama's White House account. Meanwhile, ChatGPT's inability to distinguish trusted content from malicious instructions turns web summaries into phishing surfaces, highlighting systemic AI vulnerabilities that experts warn may never be fully solved.
Consumer appetite for AI shopping agents is outpacing merchant readiness, with nearly one in three willing to trust agents with purchases up to $500. But the infrastructure to verify identity, track authorization, and resolve disputes for machine-initiated transactions doesn't exist yet, threatening billions in lost revenue and exposing critical weaknesses in the payments landscape.
Manuel Aráoz, co-founder of OpenZeppelin, has declared all of DeFi unsafe, citing AI-powered coding agents that excel at finding smart contract vulnerabilities. His warning follows April's record-breaking month of crypto hacks and over $1.1 billion in DeFi losses in the past year. The claim has split the crypto community, with some arguing AI is reshaping security while others say most exploits stem from operational failures, not code flaws.
Robinhood now allows customers to deploy AI agents that can trade stocks and make purchases autonomously. The company launched agentic trading accounts and virtual credit cards for its 700,000 Gold Card holders, complete with spending limits and fraud monitoring. The move marks a shift toward autonomous finance technology for retail investors.
South Korean authorities arrested YouTuber Kim Se-ui on charges of using AI-generated voice recordings and doctored messages to falsely accuse actor Kim Soo-hyun of dating a minor. The scandal halted the star's career for over a year and triggered a $20 million lawsuit, marking what experts call a dangerous turning point in AI cybercrime.
The House Financial Services Subcommittee heard testimony on modernizing the Bank Secrecy Act for the digital age. Crypto executives and policy experts clashed over whether to reform or repeal the 1970 law as AI-enabled scams surged 500% and illicit funds now move across wallets within 24 to 48 hours. Witnesses agreed AI in transaction monitoring is essential but disagreed on reducing reporting requirements.
Cox Media Group will pay $880,000 to settle FTC allegations that it falsely advertised an AI-powered Active Listening service capable of capturing voice data from smart devices for ad targeting. The FTC found the company was actually reselling email lists from data brokers at a markup, not listening to consumer conversations as claimed.
The Department of Health and Human Services announced a new AI-powered initiative to detect fraud and waste in health programs across all 50 states. The AERO program will use ChatGPT and other AI tools to analyze years of audit reports from Medicaid, Medicare, and federal grantees, marking a shift from reactive oversight to real-time screening of billions in federal health spending.
Apple released its 2025 App Store safety statistics, revealing it prevented over $2.2 billion in potentially fraudulent transactions and rejected more than 2 million problematic app submissions. The company's App Review team combined human expertise with AI-powered detection systems to identify malicious patterns, block 1.1 billion fraudulent account creations, and terminate 193,000 developer accounts over fraud concerns.
DataDome has unveiled Priority Protect, a virtual waiting room designed to classify human shoppers, authorized AI shopping agents and malicious bots in real time during high-demand sales events. The system uses intent-aware analysis to ensure fair access, addressing the challenge retailers face as agentic AI systems execute purchases at machine speed.
For the first time in nearly two decades, exploitation of software vulnerabilities has overtaken stolen credentials as the primary way hackers breach corporate networks. Verizon's 2026 Data Breach Investigations Report reveals that AI-powered hackers now exploit flaws in 31% of all breaches, while mobile phishing attacks achieve 40% higher success rates than traditional email scams.
Perplexity AI has restricted usage limits for numerous Pro accounts linked to promotional codes, citing widespread fraud and unauthorized resale of access codes. Users across Reddit and X reported hitting weekly caps after just a handful of queries, with some limited to 100 queries per week. The AI company says it's working to clarify the new restrictions while helping users impacted in error.
The preprint server arXiv is issuing one-year bans to researchers who submit manuscripts containing hallucinated references and other clear signs of unchecked generative AI use. After the ban, authors must have their work accepted at peer-reviewed venues before posting to arXiv again. The move addresses a flood of AI slop overwhelming the platform, particularly in computer science.
Two sophisticated attacks in April 2026 drained nearly $600 million from DeFi platforms, with cybersecurity experts attributing the heists to North Korean groups likely using AI tools to identify vulnerabilities. The Drift Protocol and Kelp DAO exploits triggered cascading failures across the ecosystem, exposing structural weaknesses in cross-chain bridges and highlighting how AI is accelerating the speed and sophistication of blockchain exploits.
