Massachusetts Electric Utility Hit by Ransomware

The Reading Municipal Light Department (RMLD), an electric utility in Massachusetts, informed customers on Monday that its systems were targeted last week in a ransomware attack.

RMLD says it serves over 68,000 residents in the towns of Reading, North Reading, Wilmington and Lynnfield Center.

The Reading Municipal Light Department (RMLD), an electric utility in Massachusetts, informed customers on Monday that its systems were targeted last week in a ransomware attack.

RMLD says it serves over 68,000 residents in the towns of Reading, North Reading, Wilmington and Lynnfield Center.

The company says the ransomware attack had no impact on the delivery of electricity, and it has found no evidence that customer financial data, which is stored on third-party systems, has been compromised as a result of the incident.

RMLD told customers that it discovered the breach on February 21 and its IT team has been working to isolate infected systems and remove the malware. It has also hired an outside IT consultant to assist its efforts.

No information has been provided on the type of ransomware or how it ended up on RMLD systems.

“RMLD takes this cyber infiltration very seriously, and staff is working tirelessly to correct this issue and restore regular business operations as soon as possible,” the company said in an alert posted on its website.

RMLD says customers can make new service requests and report outages and service issues via phone. Online payments were not impacted by the incident.

While this may have been an attack launched by profit-driven cybercriminals, electric utilities in North America have been increasingly targeted by state-sponsored threat groups over the past years.

Ransomware attacks can pose a serious threat to both small and major organizations. Over the past year, several big companies reported being hit by ransomware, including Norwegian metals and energy giant Norsk Hydro, Australian shipping giant Toll, Aircraft parts maker ASCO, Mexican oil company Pemex, and testing services provider Eurofins Scientific.

The DHS revealed recently that a piece of ransomware had disrupted operations at natural gas facilities.
