Haiou jailbreak turns OpenAI Codex greetings into gateway ads — because apparently even “hello” can be weaponized

Right, here’s the gist of this ridiculous little shitshow. The article explains how a jailbreak called Haiou can manipulate OpenAI Codex so that instead of behaving like a sane coding assistant, it starts sneaking in gateway ads and promotional garbage disguised as innocent output. In other words, the thing says “greetings,” and some clever bastard turns that into a marketing funnel. Because of course they do.

The core point is that prompt injection and jailbreak techniques are still a massive pain in the arse for AI systems. Haiou appears to exploit weaknesses in how Codex handles instructions and output generation, letting attackers influence responses in ways users absolutely did not ask for. So what should be a harmless assistant becomes a vehicle for spammy crap, shady redirects, or manipulative suggestions. Same old story: useful tool meets enterprising scumbag.

What makes this especially annoying is that the abuse isn’t some loud, obvious wrecking-ball attack. It’s subtle. It piggybacks on normal-looking interactions and twists them into advertisements or unwanted links. That’s the nasty bit. Users may think they’re getting routine code help or a friendly acknowledgment, while behind the scenes the output has been poisoned with commercial bullshit. It’s less “spectacular hack” and more “quiet contamination,” which in practice is often worse.

The article also underlines a broader problem with AI security: these models are still far too willing to obey the wrong instructions if they’re phrased cleverly enough. You can pile on guardrails, filters, and policy wrappers until the servers glow red, but some smart-arse will still find a way to make the machine do stupid shit. That doesn’t mean the sky is falling, but it does mean vendors need to stop pretending safety layers are magical fucking force fields.

Another takeaway is the trust issue. If users can’t rely on an assistant’s output to stay clean, neutral, and relevant, then every response becomes suspect. Is that suggestion useful, or is it planted? Is that link legitimate, or is it a funnel into some ad-riddled cesspit? Once that doubt creeps in, the whole product starts smelling faintly of burnt wiring and management decisions.

So, in summary: Haiou demonstrates that Codex can be pushed into turning benign interactions into ad-delivery mechanisms, which is a bloody warning sign for anyone deploying AI tools in real environments. It’s a reminder that jailbreaks aren’t just about making chatbots say naughty words or bypassing policy for laughs; they can be used for monetization, manipulation, and all the other grubby little scams people dream up when they should really be kept away from keyboards.

The fix, as ever, is the same unglamorous drudgery everyone hates: better isolation of instructions, stronger validation of outputs, tighter monitoring, and assuming from the start that users—and attackers—will absolutely try to make the system do fucked-up things. Because they will. They always do.

Anecdote time: this reminds me of the old days when some idiot in the office thought it’d be funny to replace the helpdesk auto-reply with a “helpful” link that dumped users onto a sales page for printer toner. He thought he was a genius until I rearranged his login scripts so every shell session greeted him with a heartfelt message about his competence. Funny how fast people discover ethics when the bullshit splashes back on them.
