Interserve, a multinational group of support services and construction companies, which has recently helped with constructing Birmingham Nightingale Hospital, and BAM Construct, part of Royal BAM Group, are neutralising consequences of cyber incidents which affected the companies’ systems.

The reason for the violation could have been the fact that the firms participated in NHS projects. The attackers seem to target activities implemented at the most vulnerable time when procedures are knocked out of routine.

Almost 100,000 Interserve staffers got their data compromised. The human resources database was breached leaking such personal information as names, addresses, HR notes, payroll and banking details, data about work hours. Interserve employs up to 60,000 staff members around the globe.

The multinational company has already entered a complicated phase – it was taken under control of creditors about a year ago, and auditors questioned the corporate financial status.

The stolen data is a treat for hackers who would misuse the information for social engineering purposes and make phishing incidents increase even more.
