Disclosure context

About Marketo

Marketo is a relatively obscure ransomware group that emerged in December 2021 with primarily financial motivations, having compromised 32 known victims across multiple sectors. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with no confirmed information available regarding their country of origin, connections to other cybercriminal organizations, or operational structure. Their attack methodology, encryption techniques, and specific tactics have not been extensively documented by major security firms or law enforcement agencies, though their targeting patterns indicate a focus on high-value sectors including automotive, healthcare, and government organizations. The group has demonstrated a geographic preference for victims in the United States, Italy, and the United Kingdom, suggesting either regional operational capabilities or specific interest in these markets. Due to limited public documentation from authoritative sources such as CISA, FBI, or established security researchers, detailed information about notable campaigns, ransom demands, or specific attack vectors remains unavailable in the public domain. The current operational status of Marketo is unclear based on available public intelligence reporting. The group has been linked to 32 public disclosures across our corpus. First observed on a leak site on December 7, 2021; most recent post March 14, 2022. The operation is currently inactive.
