There are also restrictions in the administration of the city of Stralsund after the cyber attack on an IT service provider.
The housing benefit office, the registry office and the processing of identity cards are affected, a city spokesman said on Monday.
In addition, the Internet service portal "OpenR @ thaus" was completely switched off on Monday afternoon, as it was said in a message.
Stralsund - The majority of specialist applications are not affected.
The Mecklenburg Municipal Service (KSM) and the Schwerin IT and Service Company (SIS) were the target of a cyber attack at the end of last week.
Schwerin's mayor Rico Badenschier (SPD) announced this on Friday.
The IT companies are responsible on the one hand for the administration and on the other hand for the municipal companies in Mecklenburg.
For this reason, according to the mayor, most of the IT infrastructure has been shut down.
In addition to the state capital, the Ludwigslust-Parchim district is also directly affected by the attack.
The city of Greifswald also reported restrictions on services on Monday.
