- Microsoft reports that email spammers are now adopting ASCII smuggling to bypass email platform filters, according to Dan Goodin at Ars Technica.
- ASCII smuggling is an AI prompt injection tactic originally designed to hide malicious instructions in attacks on AI agents, now repurposed by spammers to evade detection.
