COLUMBUS, Ohio (WCMH) – The city of Columbus is arguing that it is not responsible for the massive cyberattack against city systems last summer.

NBC4 Investigates revealed that the private, sensitive information of half a million people was leaked on the dark web as a result of the attack, despite the mayor’s claim that the data lacked value. Now, lawyers for the city have filed a motion to dismiss two class action lawsuits.

The two class action lawsuits represent both law enforcement and residents who were impacted. Right now, the court is deciding if the cases will move forward.

The city of Columbus is arguing it is not at fault for the cyberattack because the city is a political subdivision, meaning it is immune from legal claims where someone alleges harm caused by another’s actions or negligence.

The city also argues that the parties suing have not shown any specific injury because of the attack and that they did not provide enough support to justify the claim of negligence.

Those suing the city strongly disagree.

They argue that there have been injuries; one example is an undercover officer who fears that if his identity is revealed, it will threaten an ongoing criminal investigation and his life. Court documents show he now sleeps with a gun under his pillow and has installed security cameras throughout his home.

NBC4 Investigates found confidential information about undercover officers and criminal cases on the dark web after the cyberattack.

Plaintiffs also argue the city does owe a duty of care to protect personally identifiable information because it collected and stored it.

It is up to the court to decide on the motion to dismiss and as of now, the trial is scheduled for the end of August.
