Cyberattack on Boston Union Results in $6.4M Loss

A cyberattack on the Boston-based Pipefitters Local 537 union’s health fund resulted in the loss of $6.4 million.

A cyberattack on a Boston-based labor union’s health fund resulted in the loss of $6.4 million, but it does not appear that the personal information of members was stolen or compromised, union officials said.

Federal and local law enforcement agencies were notified of the attack at Pipefitters Local 537 that was discovered Feb. 7 and the union retained a cyber security forensic investigator, union business manager/financial secretary-treasurer Daniel O’Brien said in a message to members.

“This is very unfortunate news; but please be assured that nothing about your benefits with Local 537 has changed and our health fund remains well-funded,” O’Brien wrote.

Law enforcement is “optimistic” that they will be able to return the vast majority of the stolen funds, he said. The fund is also insured.

The FBI in Boston declined to comment.

O’Brien described the breach as a social engineering cyberattack and said private investigators and a cybersecurity company have completed a review of the fund office’s email server and concluded that there was no breach or hack.

Employees are receiving advanced cybersecurity training and changes have been made to the health fund’s wiring policy.

“In closing, it has been reiterated throughout the investigation to remind our membership to be mindful of what we put out online and on social media, as these are easy places for cybercriminals to gain information and locate potential targets,” O’Brien said.

The union has about 3,000 members and represents pipefitters, welders and HVAC-refrigeration workers.

Government agencies, businesses, health care organizations, and school systems around the world have been the targets of cyberattacks recently. In September, the Justice Department charged three Iranian citizens with ransomware attacks that targeted power companies, local governments and small businesses and nonprofits.
