Manroc Developments Data Breach

Storm listed Manroc Developments, a Canadian construction and mining development company, on its dark web portal on September 21, 2026. SOCRadar’s Dark Web Monitoring identified the listing. Storm’s 63 other victims in the past 60 days include several Canadian industrial companies — Melitron, Lowerys, Flexmaster, and Petrocare Construction — making Manroc a consistent geographic and sector fit for the group’s current targeting pattern.

Our stealer-log query for manroc[.]com returned no records. That query is paginated and bounded — credentials could exist under alternate domain variants or VPN-endpoint domains not captured here. Treat the null as no positive signal. Storm also uses VPN vulnerabilities and RDP as access vectors, independent of stealer logs. Credential monitoring across all known domain variants and remote-access infrastructure is the recommended next step.
