The UK Information Commissioner has warned that companies are leaving themselves open to cyber-attack by ignoring crucial measures like updating software and training staff.

The warning comes as the Information Commissioner’s Office (ICO) issued a fine of £4,400,000 to Interserve Group Ltd, a Berkshire based construction company, for failing to keep personal information of its staff secure. This is a breach of data protection law.

The ICO found that the company failed to put appropriate security measures in place to prevent a cyber-attack, which enabled hackers to access the personal data of up to 113,000 employees through a phishing email.

The compromised data included personal information such as contact details, national insurance numbers, and bank account details, as well as special category data including ethnic origin, religion, details of any disabilities, sexual orientation, and health information.

An Interserve employee forwarded a phishing email, which was not quarantined or blocked by the Interserve’s system, to another employee who opened it and downloaded its content. This resulted in the installation of malware onto the employee’s workstation.

The company’s anti-virus quarantined the malware and sent an alert, but Interserve failed to thoroughly investigate the suspicious activity. If they had done so, Interserve would have found that the attacker still had access to the company’s systems.

The attacker subsequently compromised 283 systems and 16 accounts, as well as uninstalling the company’s anti-virus solution. Personal data of up to 113,000 current and former employees was encrypted and rendered unavailable.

To better safeguard people’s data, organisations must regularly monitor for suspicious activity and investigate any initial warnings; update software and remove outdated or unused platforms; update policies and secure data management systems; provide regular staff training; and, encourage secure passwords and multi-factor authentication.
