New York City�s law department was been hit with a cyberattack that forced officials to take the 1,000-lawyer agency offline, but Mayor Bill de Blasio said he believes no data was compromised in the hack.

�To this hour we have not seen information compromised or a ransom demand,� the Democratic mayor said at a virtual news briefing on Tuesday, adding that the investigation was �evolving.�

City officials said they disconnected the law department�s computers from the city�s network on Sunday, after discovering the cyberattack.

�As the investigation remains ongoing, the City has taken additional steps to maintain security, including limiting access to the Law Department�s network at this time,� de Blasio spokesperson Laura Feyer said in a statement.

Geoff Brown, the city�s chief information security officer, who joined de Blasio at Tuesday�s briefing, said the attack was �not a ransom situation� but declined to discuss possible motives.

�We do fully expect the law department IT environment will be securely reestablished promptly so the law department can get back to the business of serving New Yorkers,� he said.

John Miller, the police department�s deputy commissioner for intelligence and counterterrorism, said the good news was that the system for detecting hackers worked.

�Once there was activity seen that was suspicious, that rang bells between cyber command and its contractors that patrol those systems looking for anomalies,� Miller said. He said the investigation was �still early in the forensics piece.�

Cyberattacks targeting government agencies as well as private companies have become an increasing threat, including last month�s ransomware attack against Georgia-based Colonial Pipeline, which caused widespread gasoline shortages.

�I think people should realize this is something that�s going to be with us for quite a while,� de Blasio said. �And we�re going to have to do a lot to focus on it and constantly protect ourselves.�
