swissdefiapp[.]de

Analysis of swissdefiapp.de, observed on 22 July 2026, identifies a high‑risk crypto drainer operation. The domain was registered on 24 February 2026 and is currently taken offline. DNS resolution points to 104.21.15.220, an address owned by Cloudflare, Inc. (AS13335) located in the United States. Both authoritative name servers, demi.ns.cloudflare.com and odin.ns.cloudflare.com, belong to Cloudflare, indicating the attacker leveraged the provider’s CDN and security services. The site presented a TLS certificate issued by Google Trust Services under the WE1 certificate authority, confirming the use of HTTPS.

HTTP headers reveal enforcement of HSTS and support for HTTP/3, typical of Cloudflare‑hosted sites. Reputation services flag the domain aggressively. Google Safe Browsing marks it as a social‑engineering threat, while Gridinsoft assigns a trust score of 0 / 100. VirusTotal reports that 4 of 93 scanned security vendors flagged the domain, reinforcing the malicious classification. The domain appears on three independent security blocklists and is explicitly blocked by PhishDestroy, MetaMask, and SEAL, all of which target cryptocurrency‑related fraud.

The page title captured during the brief crawl reads “Swiss DeFi App™ – KI‑Trading Deutschland 2026,” suggesting an attempt to lure German‑speaking cryptocurrency users. The available evidence confirms the presence of a crypto‑draining campaign, yet the exact payload, phishing page structure, and victim interaction flow remain unknown because the site was taken offline before a full content capture could be performed. Defenders should continue to monitor the IP address 104.21.15.220 for any re‑use, enforce sink‑hole routing for the domain, and update endpoint protection rules to block the identified blocklist entries.
