The International Meteor Organization (IMO) website has been the target of a cyberattack, as announced on September 14, 2026. The attack has caused major disruptions to the organization's technical systems, resulting in the replacement of its usual content with a simple waiting page. The IMO explained that a large portion of its site is currently offline due to an "aging infrastructure" that has been heavily impacted by the incident. The organization warned that some parts of the site will remain unavailable for several weeks while it transitions to new services and infrastructure. Details about the attack are still unclear. The IMO has not disclosed the date the breach occurred, the method used by the attackers to access its systems, or whether any data was accessed or encrypted. However, the need to completely rebuild the site rather than simply restore it indicates that the system may have suffered a significant compromise, requiring more than just routine repairs. Despite the ongoing issues, not all of the site's functions are offline. The IMO has prioritized restoring its fireball reporting tool, which allows users to submit observations of exceptionally bright meteors. This tool is vital for the organization's research on meteor activity and related phenomena. Other parts of the site, including databases, resources, and member sections, remain inaccessible for now as the reconstruction continues. The IMO has also used this opportunity to remind users of important guidelines for reporting observations. Users are advised not to report events that last more than 30 seconds, as most fireballs are visible for only a few seconds. They are also cautioned against reporting recurring phenomena, as fireball sightings are rare and usually unique. Additionally, users are reminded that slowly blinking lights or multiple objects moving across the sky at once are unlikely to be fireballs. The site encourages users to differentiate between fireballs and other sky phenomena like airplanes, rocket launches, or satellites, which are becoming more common in the night sky.
