Greasy Opal is a near two-decade-old developer offering a commercial CAPTCHA-solving toolkit that uses advanced OCR and machine learning to bypass account protections; its product has been used by criminal groups (notably Storm-1152) to mass-create fraudulent accounts and target government and major technology services worldwide, generating significant revenue and enabling automated, low-skill attacks at scale.
