Permanent Disclosure Ledger

The discipline, demonstrated

On behalf of our research partners, we investigate publicly distributed Android and iOS apps: we decompile them, follow their code and data flows, and trace every connection to the servers it reaches. Hundreds of agents work through each app and join the technical evidence into one picture, which our specialists then review and verify.

Critical
Atruvia is the shared technology provider behind 118 German cooperative banks serving about 30 million customers, and its banking app has no certificate pinning anywhere, meaning a single compromised certificate authority could intercept the entire banking session for any of those customers. The same app also collects exactly how you type and how hard you press the screen before its own consent banner has fired, sending that data to a US company. A generic acknowledgment arrived once, naming none of the findings, and nothing followed it.
de.sparda.banking.app v9.0.0, built by Atruvia AG. All four findings re-scored under CVSS v4.0. The complete absence of certificate pinning at any layer, no network security config, zero configured OkHttp pins across all three DEX archives, reaches CRITICAL/9.1 on the computed CVSS score alone. LexisNexis ThreatMetrix BehavioSec (correction: earlier internal notes named this ThreatMark, the actual vendor confirmed in smali is LexisNexis ThreatMetrix), a behavioral biometrics SDK capturing keystroke and touch dynamics in the app's own full-screen banking WebView with zero references to the app's own OneTrust consent platform, transmitting to US servers, reaches HIGH/8.7. AD_ID+AppsFlyer attribution and a hardcoded pre-consent Firebase key both correct to MEDIUM. Atruvia builds this app for 118 German cooperative banks (Volksbanken, Raiffeisenbanken, Sparda-Banken), ~30M customers, confirmed via 118 bank IDs in the app's own Adobe Launch config. Seven messages sent across 48 days; one generic acknowledgment received 1 July naming none of the four findings, no further reply since. Case closed and published 2026-09-25, on the stated embargo date.
