Description
The incident involving the website of Markt Murnau in Bavaria was first detected around May 10-11, 2022, when CSU parliamentary group leader Rudolf Utzschneider noticed unauthorized casino advertisements embedded within the municipality's official homepage content. The compromised section displayed promotional text encouraging visitors to "try their luck together with the casino," directly following legitimate information about the municipal council structure. Utzschneider documented the anomaly through screenshots and immediately alerted authorities, recommending colleagues avoid all municipal IT systems pending investigation. Initial analysis suggested the breach likely occurred during the overnight hours between Tuesday and Wednesday, though exact timing remained unconfirmed. Municipal spokesperson Annika Röttinger confirmed the advertisements were unauthorized, clarifying that the town neither placed nor permitted third-party advertising on its digital platforms. The municipality promptly engaged its external website hosting provider and launched an internal review while filing a criminal complaint under German Penal Code §§202 (data espionage) and 303 (computer sabotage) with Murnau police.
Technical investigation revealed the compromise affected only the externally hosted public website, with no penetration detected into internal municipal networks or critical systems like citizen information portals or online services. Röttinger emphasized the separation between public-facing systems and secure internal infrastructure, confirming no operational disruptions to municipal functions or citizen-facing digital services. While the specific attack vector remained undetermined, the municipality highlighted its existing security certifications including the Bavarian E-Government Act compliance and the "Communal IT Security" seal from Germany's Federal Office for Information Security (BSI). Security protocols included regular IT staff training and external provider oversight. Utzschneider raised concerns about potential phishing or ransomware risks despite no evidence of such secondary attacks, prompting calls for reviewing preventive measures. The municipality maintained normal operations throughout the incident but faced scrutiny regarding website security controls and intrusion detection capabilities. No data theft or financial impacts were reported, though the unauthorized content remained publicly visible for an unspecified period before removal.
