S.E.M.P. s.r.l. Data Breach

S.E.M.P. s.r.l., a manufacturing company based in Italy, was listed as a victim on the Qilin ransomware group’s leak site on August 23, 2026. The company operates within Italy’s industrial manufacturing sector. S.E.M.P. s.r.l.’s listing is one of several Italian manufacturing and services firms added to Qilin’s site in the same period, consistent with the group’s ongoing focus on European industrial targets. Over the past 60 days, Qilin has claimed approximately 210 victims, with Manufacturing ranked as its top targeted industry ahead of Professional Services and Other. The United States, Germany, and Italy are the group’s leading victim geographies. Among Qilin’s manufacturing targets in the current dataset, Black Cat Engineering & Construction WLL (Qatar) and Gindre India (India) share the manufacturing classification, while Aurore Development S.p.A. and Studio BOLDRIN PAOLO represent the broader Italian cluster affected in the same timeframe. S.E.M.P. s.r.l. aligns squarely with Qilin’s core targeting profile — a mid-market Italian manufacturer with limited public security visibility.

Initial-access correlation against SOCRadar’s stealer-log telemetry returned no records for www.semp.it in the queried slice. A null result is not the same as a clean bill of health — the sample is paginated, alternate domains and personal email aliases fall outside this query, and credentials may have been used and rotated before indexing. Infostealer-sourced credentials remain one of the most reliable initial-access vectors for ransomware groups operating at scale. While no stealer-log evidence was surfaced for this domain in this query, the absence of a finding in a paginated sample is not equivalent to confirmed clean posture. Qilin’s operational profile is consistent with phishing, exposed VPN appliances, and recycled credentials as entry paths; affected organizations are advised to audit authentication logs, enforce MFA on internet-exposed services, and treat the listing itself as an indicator that the threat actor has gathered sufficient operational intelligence about the target.
