Description
On March 13, 2025, the Baltimore City Comptroller’s Office alerted authorities to a cyberattack and identity theft that had defrauded the city of more than $1.5 million. The Federal Bureau of Investigation is now investigating the incident. According to Deputy Comptroller Erika McClammy, the perpetrator used the names of city employees with whom they had gained trust, combined with information about a vendor and publicly available online data. The attacker assumed the identity of a current vendor employee to infiltrate the city’s accounts payable system. Initial contact with city personnel was established in the fall of the previous year, around October or November, and the relationship was nurtured over several months with multiple employees across various departments. After establishing trust, the attacker altered the banking details on file for the vendor.

In February, a check for $803,000 was issued based on the fraudulent banking information and was successfully cashed. A second check for $721,000 was prepared in March, but the bank flagged the transaction and returned the funds to the city. Upon detection, the city immediately froze the account designated for the vendor to prevent further unauthorized transfers. McClammy noted that the attacker bypassed the city’s geofencing controls by using an Internet Protocol address routed through a Starlink connection. The full scope of the attack remains uncertain, and officials have indicated that other municipalities or agencies may have been targeted as part of the same campaign. The Baltimore City Office of the Inspector General has been asked to conduct its own investigation into the matter. The vendor, which works with the Baltimore City Department of Public Works, is scheduled to receive its rightful payment this week. While current protocols were followed, McClammy acknowledged that the incident demonstrates a need to enhance existing security measures. When questioned about whether the city’s human resources and payroll system, Workday, remains vulnerable to similar Starlink‑based attacks, McClammy stated that she cannot confirm any ongoing risk.
