On 17 August 2026, Berlin’s Senate Chancellery reported that a hacker attack had targeted the city’s Landesnetz, a secure high-speed network connecting around 600 government and public sites. The attack was discovered during forensic investigations, according to statements from the Chancellery. Two Senate administrations, the Senatsverwaltung für Stadtentwicklung, Bauen und Wohnen and the Senatsverwaltung für Mobilität, Verkehr, Umwelt und Klimaschutz, were taken offline as a precaution on 14 August. The disconnection was intended to prevent further damage, though the extent of the breach remains unclear. Both departments have been cut off from internet and email communication since Friday evening, as reported by rbb24. A crisis unit led by Berlin’s information security commissioner was established to investigate the attack. The unit includes the Landeskriminalamt (LKA), the Berlin public prosecutor’s office, and the Bundesamt für Sicherheit in der Informationstechnik (BSI). The public prosecutor’s office confirmed to dpa that an official investigation had been launched. The Senate Chancellery stated that no further details on the attack’s scope or origins could be provided due to ongoing investigations. It is unclear whether sensitive data was stolen during the attack or how long the affected administrations will remain offline. Employees at one of the departments told Der Tagesspiegel that they were "practically incapacitated" without internet or email access. The Landesnetz, operated by ITDZ Berlin, is a fibre-optic network used exclusively by Berlin’s government. ## What the coverage left out None of the digests or full reports specified whether the attack involved ransomware, malware, or another form of cyber intrusion. The full reports from derwesten.de and Tagesschau did not mention whether the affected administrations had backup systems or contingency plans for operating without network access. None of the right-rated digests mentioned the involvement of the BSI in the investigation. ## Who covered it Shares of the 10 covering outlets with a published leaning rating: - Left: 10% (1) - Centre: 30% (3) - Right: 60% (6) 6 of 16 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-08-17T18:30:32.243949+00:00. **Coverage watch:** developing. Checked 6 times; 0 checks found a material change. Most recently checked 2026-08-17T19:15:14.663Z. ## How the sides framed it ### Left - The single left-rated digest, from Zeit Online, led on the fact that parts of the Berlin Senate administration had become victims of a cyberattack under investigation. It noted that it was unclear whether data had been lost, matching the emphasis of the centre-rated reports on the uncertainty surrounding the breach’s impact. ### Centre - All three centre-rated reports, derwesten.de, Tagesschau, and Der Tagesspiegel, led on the precautionary disconnection of the two Senate administrations and the establishment of a crisis unit. Tagesschau and derwesten.de both highlighted the involvement of the LKA, Berlin public prosecutor’s office, and BSI in the investigation. Tagesschau quoted the Senate Chancellery’s statement that no further details could be provided for "investigative tactical reasons." - derwesten.de included a sidebar listing five major hacker attacks in Germany since 2015, including the 2015 Bundestag breach and the 2021 ransomware attack on Anhalt-Bitterfeld. The report also quoted a spokesperson for the public prosecutor’s office confirming the launch of an official investigation. Tagesschau and Der Tagesspiegel both noted that the affected administrations had been cut off from internet and email communication, with Der Tagesspiegel quoting an employee describing the departments as "practically incapacitated." ### Right - The four right-rated digests, Handelsblatt, Bild, Berliner Morgenpost, and focus.de, all led on the attack’s disruption to government operations. Bild and Der Tagesspiegel both quoted an employee describing the affected administrations as "practically incapacitated," though only Der Tagesspiegel’s full report carried the quote. Handelsblatt and focus.de emphasised the unknown extent of the attack, with Handelsblatt’s headline describing the situation as "extent unknown." - Bild’s digest was the only one to frame the attack as having left authorities "practically incapacitated" in its headline. Berliner Morgenpost’s digest noted that abnormalities were detected in the protected network of authorities, leading to the precautionary disconnection of the two Senate administrations. **Provisional coverage gap:** left. The watch is not closed, so this is not yet a settled blindspot finding. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - mixed: 2 - high: 5 - unknown: 7 - veryHigh: 2 ## Verification scope This page compares coverage and scores the source reporting.
