Cyber Threat Actor: OpSeaWorld

OpSeaWorld is an alias used by a threat actor group.
The group is known to operate from the United States of America.
Public reporting identifies OpSeaWorld as a hacktivist collective.
The alias appeared in connection with a specific incident in February 2015.
No other names or affiliations have been publicly attributed to OpSeaWorld beyond this incident.
The group’s presence in open‑source intelligence is limited to the single reported event.

On February 10, 2015, individuals acting under the OpSeaWorld name compromised the website of imata.org.
imata.org is the online presence of the International Marine Animal Trainers Association.
The attackers gained unauthorized access to a user database hosted on the site.
They exfiltrated the database and extracted 1,445 username entries.
Each username was accompanied by its corresponding hashed password.
The leaked credential set was subsequently posted to a public Twitter account associated with the operation.

This remains the only publicly reported operation linked to the OpSeaWorld alias.
No additional incidents, malware families, tooling, or infrastructure have been associated with the group in open sources.
Consequently, details about their typical targets, geographic focus, or strategic objectives are not available.
The absence of further reporting prevents any assessment of recurring patterns or broader campaigns.
Therefore, the profile is confined to the verified facts surrounding the 2015 imata.org breach.
No speculation beyond the documented event is warranted.
