What happened

According to the ransomware tracker RansomLook, the n0n ransomware group listed “Hallmark Cards, Inc.” on its leak site. RansomLook dates the entry 2026-11-06 and describes the listed organisation as “greeting cards and gifts retail” in the United States.

This is a claim made by the group. The listing does not prove that a breach happened. Hallmark has not confirmed an incident in the sources provided. No independent outlet has verified the claim. The entry point, the type of data involved and the data volume are not confirmed.

RansomLook also shows an earlier, unnamed entry, “Company #121”, dated 2026-11-03 with the same sector description. The sources do not confirm whether it refers to the same organisation. The same tracker shows the group has made many listings in recent weeks, according to RansomLook.
