Editorial Notes
REJECTED - Source credibility issue
Reason: The source pasqualepillitteri.it is a personal blog, not an established security or tech news outlet. The breach details cannot be independently verified.
Action: If/when mainstream security news sources (BleepingComputer, The Register, Ars Technica, etc.) or MoneyForward’s official communications confirm this breach, the story may be reconsidered for publication.
Value if confirmed: The story would have merit as a GitHub security best practices lesson for developers and a fintech security case study.
