Ransomware attack disrupts DuPage County judicial and law enforcement systems

DuPage County, Illinois, is reporting it has become the target of a ransomware attack affecting multiple county departments, including the sheriff's office, the 18th Judicial Circuit Court, and the DuPage County Circuit Court Clerk's office. 

The cybersecurity incident was detected on Monday 28th of April when computer outages occurred at the courthouse and sheriff's office in Wheaton. County officials initially described it as a "cyber incident" but later confirmed it was a ransomware attack.

The attack has forced county officials to take affected systems offline while technical personnel work to determine the full extent of the breach. Several services have been disrupted:

1. Zoom online court sessions are unavailable
2. Many court cases are being postponed, with new dates to be issued once systems are restored
3. Some lawyers and judges have reverted to writing court orders on paper
4. Chancery sales in the sheriff's office, including foreclosures, have been canceled for the week

Officials emphasiz that the impact on critical services has been contained:

• The sheriff's office has indicated there is no impact to jail operations
• In-person court hearings are proceeding as scheduled
• County operations outside the affected departments remain unaffected

No details are disclosed about number of affected individuals or types of exposed data.

According to the Daily Herald, which reportedly viewed a copy of the ransom note, the attackers claim to have stolen files from county systems, including financial records and lawsuits and demand an undisclosed amount of money in exchange for a decryption key to restore access to the compromised files.

The county has contacted both the FBI and U.S. Secret Service to assist with the investigation and the DuPage County Bar Association has issued warnings to its members about the service disruptions
