Following the mass ransomware cyber attack and the infection of the NHS systems last week, we thought it would be helpful to share some answers to your questions.

What is ransomware?

Exactly what it says on the tin; Ransomware is a particularly complex computer virus. If it gets onto a computer it searches for personal files, encrypts them and forwards the decryption code to an online server. When you next login a pop-up message appears demanding a ransom to unlock your files. The ransom is usually paid in cryptocurrency such as Bitcoin, and then you receive the code to unlock your files. Of course, paying the ransom doesn’t guarantee that you will receive a decryption key.

Ransomware Cyber Attack on the NHS

The media headlines suggest a deliberate attack on the NHS, but this is untrue. The ‘Wannacry’ virus exploited a weakness particularly found in Windows XP systems (still widely used by the NHS). And, although Microsoft fixed the problem three months ago, many larger organisations had not yet installed the patch. This is likely to be down to the complex nature of systems such as those employed by the NHS. It takes time for their IT teams to deploy patches; first ensuring that the patch doesn’t cause another problem. The old medical mantra of ‘first do no harm’ rings true here. Smaller companies can often install patches quickly as their systems are less complex. The real cost to the NHS will be potentially significant system downtime caused by the attack.

Backup and update

Backup your data! If you have a backup you can reboot your system to a point before a virus attack. The more frequently you backup, the less data you’ll lose by restoring to an earlier point. Your backup should be stored away from your principal system. If you don’t have a backup and have been infected by ransomware, stop using the system and contact your IT provider. They may still be able to recover some data. The longer you continue using your system, the more it reduces the chances of data recovery. As well as a backup, ensure you have the latest security updates for your operating system. Install and update high-quality malware and anti-virus protection.

The extensive use of Windows XP has contributed to the fast spread of this virus. Although Microsoft issued a patch for this particular virus; it doesn’t regularly issue security updates for XP. But XP systems were not the only ones affected. While this attack is primarily against Windows systems, other operating systems are always vulnerable to viruses. Even Macs can become infected with viruses.

Keep calm and be vigilant

Backing-up and ensuring up-to-date antivirus and operating systems will help protect against the current attack and future viruses. Use your system as normal, but be particularly careful about opening email links and downloading files. Remember that emails from friends and family might also be infected.
Your system is always at risk and will continue to be after this has blown over. The media has reported this event extensively because of the enormous scale and high profile victims. This is not a one off.

Daily backup and secured premises

CAS servers, running on an uninterrupted power supply are backed up daily using advanced Quantum RDX Data Tape. Each day the cartridges are swapped over and that day’s tape secured in a Turtle RDX 10 padlocked case; waterproof and double-walled for extra protection against impact and temperature extremes. The case is then removed to an alternative building within our secure gated compound and placed in a securely locked Profile NT Fire 017 fire-resistant cabinet.

All members of staff have signed confidentiality agreements, and have been checked through either the Criminal Records Bureau (CRB) or the Disclosure and Barring Service (DBS). The secure gated perimeter is monitored using CCTV M12 Mobotix recording cameras, to ensure 24/7 record of any activity. Video and audio records are backed up off-site. The storage facilities are fitted throughout with an optical fire beam protection system and air quality monitoring. Redcare security alarms are linked directly to police and fire brigade.
