1. Executive summary
The qilin ransomware group listed Pergande, a German victim, on its leak site on 2026-10-18. The listing is indexed by ransomware.live and carries no technical detail: no initial access vector, no malware sample, no exfiltration evidence, and no negotiation status. No CVE is associated with this item, and no CISA KEV entry or EPSS score applies. The bottom-line risk to EMEA financial services is indirect: qilin is an active double-extortion operation that recruits affiliates and reuses access brokers, so the listing is a sector-relevant signal rather than a specific exposure for any client. Clients with Pergande in their supply chain or counterparty set should treat the listing as an unconfirmed compromise claim until the victim or a national authority corroborates it.
2. Regulatory framing
No specific DORA/NIS2 article is directly engaged by this item.
3. Technical analysis & attack chain
The source material does not support a confirmed attack chain. The only facts present are the group name (qilin), the victim name (Pergande), the country (DE), and the victim website (www.pergande.de). No initial access vector, exploited component, CVE, payload, persistence mechanism, command-and-control channel, lateral movement path, exfiltration method, or impact detail is given. The ransomware.live entry includes a DNS records section and a leak screenshot placeholder, but neither contains populated values in the material provided.
What can be said with confidence is limited to the listing itself: qilin operates a double-extortion model in which victims are named on a public leak site, typically after data theft, and the listing is the operator's claim rather than verified evidence. The absence of a screenshot or sample in the indexed entry means the claim is unverified at the time of writing.
Attribution is unconfirmed. No MITRE ATT&CK profile for qilin is present in the material supplied, so the group's tooling, TTPs, and affiliate structure cannot be stated here. Any mapping of this listing to a specific intrusion set, access broker, or initial access technique would be speculation and is not included.
Confidence caveat: this advisory rests on a single source (ransomware.live). The listing is single-sourced and unverified; treat the victim claim as unconfirmed until Pergande, a German authority, or a second independent source corroborates it.
4. Mitigation & containment
The source provides no vendor fix, no CVE, and no technical indicators, so the actions below are process and resilience controls rather than patch guidance. They are prioritised for clients that hold Pergande in a supplier, counterparty, or shared-services relationship.
P1 (within 24h)
- Confirm whether Pergande appears in your third-party register, active contracts, or data-sharing arrangements. If it does, request a written status from the relationship owner and suspend any non-essential data exchange with www.pergande[.]de until the claim is confirmed or denied.
- Check mail, file-transfer, and API logs for traffic to or from pergande.de over the last 30 days. A confirmed listing often precedes or follows credential reuse against connected parties.
- Verify that backups for any system sharing credentials or trust with Pergande are offline or immutable, and test one restore.
P2 (within 72h)
- Review identity provider logs for authentication from German IP space or from service accounts that interact with Pergande systems. Rotate credentials for any account that authenticated to a Pergande-hosted service in the last 90 days.
- Confirm that EDR and mail filtering are enforcing, not just alerting, on the endpoints and mailboxes that touch the relationship.
P3 (within 7 days)
- Add the qilin group to your threat-intelligence watch list and re-check the leak site weekly for Pergande updates and for sector-adjacent victims.
- If the relationship is material, exercise the incident-notification clause in the contract and confirm the counterparty's own reporting obligations are being met.
No patch, version pin, or vendor fix can be named because the source identifies no affected product.
5. Indicators of compromise
No indicators of compromise available in the source material.
The only observable is the victim domain itself, which is not a malicious indicator and is not reproduced as one. No hashes, IPs, URLs, filenames, registry keys, or behavioural telemetry are present in the source.
6. Detection
Insufficient indicators to author detection rules.

8. Adverse Trace position
Adverse Trace assesses this item as low technical severity and moderate sector relevance. There is no CVE, no CISA KEV entry, no EPSS score, and no exploitation state to act on, and the listing is single-sourced and unverified. The client impact is limited to organisations with a direct Pergande relationship or shared trust; for everyone else it is a watch-list item, not a response item. We will monitor the qilin leak site for Pergande updates and for additional EMEA financial services victims, and we will reissue this advisory if a second independent source corroborates the claim or if technical indicators emerge. Clients with a Pergande dependency should contact their Adverse Trace analyst to scope the relationship review.
