M800 and CINNOX Listed by Beast Ransomware Group

Your account credentials with M800 and CINNOX may now be listed for sale or extortion on a ransomware leak site. The group Beast has published a listing for both companies on its leak site, according to records tracked by RansomLook. As of writing, neither M800 nor CINNOX has publicly confirmed that any breach or data theft occurred.

The filing date is September 10, 2026. The record does not state how many people were affected, nor does it name any categories of information that were taken.

What a Leak-Site Listing Actually Establishes

A ransomware or extortion group posting a company name on a leak site is a claim, not proof. These crews frequently publish listings to pressure victims into paying, and the published material is sometimes recycled from older unrelated breaches, exaggerated, or entirely fabricated. The presence of the listing on Beast’s page does not, by itself, confirm that M800 or CINNOX suffered a ransomware attack, that any customer data was taken, or that the data is authentic.

Real confirmation would require an admission by the company, a regulatory filing that describes an actual incident, or independent technical evidence that the published samples match real customer records. None of those exist here. Until such confirmation appears, this remains an unverified accusation. That uncertainty matters: it changes how urgently you should act on the password risk versus how much worry you invest in broader identity consequences that have not been established.

The Current Pattern of Ransomware Leak-Site Pressure

Ransomware groups have turned leak sites into a standard part of their playbook. They list companies whether or not a full compromise occurred, hoping the public embarrassment or fear of regulatory scrutiny will force payment. This pattern mixes genuine incidents with noise. For you, the practical takeaway is simple: every new leak-site mention should trigger the same narrow response — secure any potentially exposed credential immediately, then wait for official confirmation before assuming wider data loss.

Because no categories of information were named and no scale was given, you cannot know from this record whether your specific data was involved. The only reliable way to find out remains a direct notification from M800 or CINNOX. If you have not received such a letter, it is more likely that your records were not included, but anyone who has changed address since the events in question should contact the company directly to confirm their status.
