Disclosure context

About Mallox

**Overview:** Mallox is a financially motivated ransomware group that emerged in November 2022, operating as a relatively new player in the ransomware ecosystem with a focus on extracting monetary payments from victim organizations across multiple industry sectors. **Origin & Affiliation:** The group's country of origin and specific affiliations remain largely undocumented by major threat intelligence organizations, though their operational patterns suggest they operate independently rather than as part of a larger ransomware-as-a-service operation. **Attack Methodology:** Limited public documentation exists regarding Mallox's specific attack vectors and technical capabilities, though their successful compromise of 49 documented victims suggests they employ conventional ransomware deployment methods including data encryption and likely extortion tactics to pressure victims into payment. **Notable Campaigns:** Mallox has demonstrated a preference for targeting technology companies, business services, and manufacturing sectors, with their operations showing particular concentration in the United Kingdom, India, and the United States, though specific high-profile incidents have not been widely publicized by major cybersecurity firms or law enforcement agencies. **Current Status:** The group remains active as of recent threat intelligence reporting, continuing to conduct ransomware operations across their preferred geographic and sectoral targets. The group has been linked to 49 public disclosures across our corpus. First observed on a leak site on November 4, 2022; most recent post July 15, 2024. The operation is currently inactive.

About the victim

AI dossier — public-source company profile

Compass Infrastructure Group, LLC is a civil engineering design firm based in Columbus, Ohio, providing bridge, roadway, traffic, and survey services across Ohio and Kentucky. The company offers civil engineering design and project management services and operates across multiple project locations in the region.

Attack summary

Severity: high — Data has been confirmed published (disclosed status: data_published) across three archive files, indicating actual exfiltration and full public release of company data. While the sector is civil engineering rather than healthcare or government, engineering design data (bridge, roadway, infrastructure plans, project management records) can be sensitive and the publication is complete rather than a mere listing.

Mallox claims to have exfiltrated data from Compass Infrastructure Group and has published the data in three password-protected archive files (COMPASS.7z.001–003) via AnonFiles links, indicating full data publication rather than a ransom negotiation stage.
