Attack summary

Severity: medium — Data has been published by a named threat actor against a listed public company in a critical supply-chain sector (automotive robotics and EV battery assembly). However, the leak post provides no inventory of specific data types, no proof files/screenshots, and no detail of what was actually exfiltrated or encrypted, making it impossible to assess true sensitivity or operational impact.

The threat actor claims to have accessed Wooshin Safety Systems' systems and published data. The post does not specify whether encryption, exfiltration, or both occurred, nor does it detail the scope or nature of the data compromised.

What the group claims

wooshinsys.co.kr wooshinsys.com finance.yahoo.com/quote/017370.KS/financials/ WOOSHIN SAFETY SYSTEMS CO LTD (KOSPI: 017370, founded 1984, Siheung/Seoul, South Korea) is a global car-body automation specialist — building robotic welding assembly lines for 40+ automakers (GM, Ford, Stellantis, Volvo, Hyundai/Kia, Rivian, Tata) — and the only company in the world that also builds EV battery module/pack assembly lines, giving it a unique edge as carmakers merge body and battery production. It also manufactures auto parts (body doors, seat belts via Wooshin Safety Systems, interiors), with seat-belt order backlogs around KRW 2 trillion (Ford F-150, GM Silverado EV, Stellantis Jeep Compass). Financials are cyclical: record 2024 revenue of KRW 563.6B (OP ₩36.1B) fell 31% to ₩388.6B in 2025 on fewer automation orders, and Q1–Q2 2026 posted operating losses as orders slipped — though analysts (Kiwoom BUY target ₩9,500, SK Securities ₩13,000) forecast a 2026–27 recovery to ~₩451–543B revenue.

Disclosure context

About thegentlemen

thegentlemen is a ransomware group that emerged in September 2025, operating with apparent financial motivations based on their broad targeting of commercial sectors. The group has documented 267 victims across multiple countries, with primary focus on the United States, Thailand, France, Brazil, and India. Their targeting strategy demonstrates a preference for high-value sectors including manufacturing, technology, healthcare, and financial services organizations. Given the group's recent emergence and limited public documentation from established threat intelligence sources such as CISA, FBI, or major security research firms, specific details regarding their country of origin, operational structure, attack methodologies, encryption techniques, and whether they employ ransomware-as-a-service models remain unclear. The relatively high victim count of 267 in a short operational timeframe since September 2025 suggests either an aggressive campaign pace or potential inflation of victim numbers through affiliate operations, though without corroborating intelligence reports, the group's exact operational capabilities and notable campaigns cannot be definitively established. Current intelligence indicates the group remains active as of late 2025, though comprehensive threat profiling requires additional validated reporting from authoritative cybersecurity sources. The group has been linked to 922 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post October 3, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means WOOSHIN SAFETY SYSTEMS CO LTD appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, KrCERT/CC (South Korea), as required for your jurisdiction.
Monitor for the data appearing on thegentlemen's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
