Compromised host notice
A threat-intelligence feed listed a file on reinigung-kosanke.de as distributing malware (last seen 2026-09-29). TrustSniffer's evidence indicates that the site itself was compromised: the listing concerns a file placed on it by someone else, and the site's owner is most likely a victim, not the actor.
Until the file is removed, downloading anything from this site is not safe. If you run this site, remove the listed file, update the site software and its plugins, change its passwords and review it for other unauthorized changes.

Full analysis
Security Alert
Sophos flagged this site in external intelligence checks, indicating elevated compromise/scam exposure that requires immediate caution.
This website presents Glas & Gebäudereinigung Kosanke, a regional cleaning service in Bad Bramstedt, Germany, offering private and commercial customers window, facade, building, specialist, solar, and post-construction cleaning through a contact-driven service model.
Scam/Impersonation Risk
The site's visible content resembles a small-business service brochure: it identifies the Kosanke cleaning business, describes cleaning services, provides contact routes, and does not present a login form, payment workflow, cryptocurrency feature, or other obvious phishing mechanism. However, this benign page presentation is materially outweighed by external threat intelligence: the domain has a confirmed blacklist status, with multiple malicious detections and an additional suspicious detection, including a Tier 1 security-provider alert. This is a confirmed external contradiction and creates a high risk for sensitive interaction, even though the available page analysis found no explicit brand-impersonation or phishing pattern.
- The homepage and service pages describe a local cleaning business and contain no login or sensitive-data form; behavioral testing recorded no hidden forms or wallet activity.
- External reputation checks recorded 3 malicious and 1 suspicious detections, and the domain was marked by an external blacklist.
- The site links to Facebook and Twitter profiles, but these social references do not neutralize the external threat findings.
Regulatory Verification Notes
The site provides an apparent business identity and links to dedicated Impressum and Datenschutzerklärung pages, but the supplied material does not establish independently verified ownership or regulated status. No regulatory license or license number is claimed; for a cleaning-service business this is primarily a transparency and identity-verification matter rather than proof of wrongdoing. A third-party broker-intelligence check produced no match, which is a limited contextual signal and not a licensing or legal determination.
- The homepage identifies “Glas & Gebäudereinigung Kosanke” in Bad Bramstedt and describes service delivery to private and commercial customers.
- Internal navigation includes “Über uns,” “Kontakt,” “Impressum,” and “Datenschutzerklärung” pages.
- The site is hosted on AS197540, netcup-AS – netcup GmbH, DE; the resolved infrastructure is associated with Austria.
- TLS uses issuer YR1 with DV validation and is valid to 2026-12-06T10:39:07+00:00.
What to Verify Next
Before any sensitive engagement, an organization should independently compare the business name, address, telephone details, and responsible legal entity shown on the site against official German business records and an independently sourced local contact channel. The relevant authority or contracting counterparty should also confirm whether any sector-specific registration, insurance, or commercial documentation is required for the proposed service. Until those checks are complete, interaction should remain limited to low-sensitivity information exchange, with no credential submission or payment based solely on the website.
- The contact and Impressum navigation provides the pages to use for an independent legal-identity comparison.
- The site presents a telephone contact, address, and contact options that can be validated through a separate offline or independently sourced channel.
- The site has no sensitive form, so verification should be performed outside any request for credentials or financial information.
Summary Verdict
The overall posture is low trust with elevated sensitive-interaction risk. The site's service presentation is coherent, but the confirmed external threat and blacklist findings are decisive contradictions that prevent the website from being treated as a reliable basis for sensitive engagement.
Infrastructure Integrity
The site resolves directly to two likely origin addresses, with no detected CDN, edge-IP layer, or WAF vendor. This provides limited infrastructure-level mitigation and does not offset the external reputation concerns.
- Hosting infrastructure reports 2 unique IPs, 0 edge IPs, and 2 likely origin IPs.
- No CDN or detected protective infrastructure vendor was identified.
Closing Assessment
Prospective counterparties should independently authenticate the business and use an established offline or separately sourced channel before sharing credentials, making payments, or entering into a service commitment.

About this assessment
A trust score summarises the evidence TrustSniffer could collect about reinigung-kosanke.de at assessment time. It is a starting point for your own judgement, not a guarantee: a high score means the signals were consistent with a legitimately operated site, a low or critical score means several risk patterns were present.
TrustSniffer assesses a website from the evidence it can collect at a point in time: domain registration and age, hosting and certificate, the content the site served, and third-party reputation feeds. A score is a summary of that evidence, not a guarantee and not a legal finding. There is no human rating and no user review in it. A site can change after it is assessed.
