(TNS) — The hack of the city Law Department is causing major delays in high-profile lawsuits over the NYPD’s response to racial protests last summer, a new court filing revealed Wednesday.

Lawyers for protesters and the state attorney general’s office wrote in a letter in Manhattan Federal Court that their adversaries in the Law Department seemed in the dark about the scope of the hack now in its fourth day.

“My sense on the call was that they very much do not have it under control and do not know what’s going on,” said Joshua Moskovitz, another attorney on the protest cases.

But city officials refused to say whether the Law Department used multifactor authentication at the time of the hack.

A Law Department spokesman declined to comment on the matter aside from saying that discussing it in public is…
