What happened
Hasbro, the company behind brands such as Monopoly and Transformers, found hackers in its network in late March 2026. In the weeks that followed, the company was still largely offline and its website was unavailable.
The disruption was serious enough that Hasbro could not file its quarterly report with the SEC on time. In May it said the attackers were gone. It also disclosed that personal information of a few hundred employees was affected. Hasbro did not say whether it paid the hackers.
Why it matters
Public companies must report material cyber incidents and file financial reports on time. When finance systems are down, reporting deadlines become a second crisis. The Hasbro case shows that recovery planning must cover finance and compliance processes, not only websites and email.
Lessons for your organization

- Keep offline copies of the information needed to run finance during an outage.
- Rehearse the first 72 hours of a major incident with leadership.
- Communicate with employees promptly when their data is affected.
