🔍 Cybercriminals have abused X's AI assistant Grok to amplify phishing links hidden in paid video posts, a tactic researchers have dubbed 'Grokking.' Attackers embed malicious URLs in video metadata and then prompt the bot to identify the video's source, causing it to repost the link from a trusted account. The technique bypasses ad platform link restrictions and can reach massive audiences, boosting SEO and domain reputation. Treat outputs from public AI tools as untrusted and verify links before clicking.

🔍 Cybersecurity researchers have flagged a technique dubbed Grokking that attackers use to bypass X's promoted-ads restrictions by abusing the platform AI assistant Grok. Malvertisers embed a hidden link in a video's "From:" metadata on promoted video-card posts and then tag Grok in replies asking for the video's source, prompting the assistant to display the link publicly. The revealed URLs route through a Traffic Distribution System to drive users to fake CAPTCHA scams, malware, and deceptive monetization networks. Guardio Labs observed hundreds of accounts posting at scale before suspension.

🛡️ Guardio Labs researcher Nati Tal reported that threat actors are abusing Grok, X's built-in AI assistant, to surface malicious links hidden inside video ad metadata. Attackers omit destination URLs from visible posts and instead embed them in the small "From:" field under video cards, which X apparently does not scan. By prompting Grok with queries like "where is this video from?", actors get the assistant to repost the hidden link as a clickable reference, effectively legitimizing and amplifying scams, malware distribution, and deceptive CAPTCHA schemes across the platform.
