The official French health sector cybersecurity body (ACSS) and the digital health agency (ANS) issued an alert in mid March warning that the coronavirus is being exploited by cyberattackers.
The ACSS received alerts concerning pseudo Covid-19 information messages which are in reality computer viruses. "Cybercriminals are trying on a global level to exploit fear linked to the pandemic to infiltrate computer networks for companies and individuals alike". Typically threats emanate from "false e-mails from health authorities, fake internal company messages or fake delivery delay messages".
The ANS strongly encourages its members in healthcare to supervise any IT abnormalities, to ensure the smooth running of the backups and spread awareness of the risks currently faced. Almost half of all malicious incidents originate from an email or cryptovirus.
The ACSS receives on average 27 reported incidents per month. 88% of these are from public or private hospitals or clinics. 46% of all incidents have forced the establishment to run a degraded IT system for managing patient care.
Even more worrying, 5 incidents have even caused potentially life threatening issues for the patient. The current Covid-19 crisis is putting health sector IT systems at increased risk because any system under extreme tension is obviously more fragile.
Here are the 3 principal strategies - prevention, resistance, assurance- that you must not neglect when it comes to cyberattacks:
Prevent – detect and stop intrusions
- Install and update anti-spam and anti-phishing tools
- Update operating systems and business applications
- Reset passwords regularly
- Inform and train all workers on increased cybersecurity risks. Digital hygiene must be a top priority in all hospital and medical environments
Resist - prevent propagation
- Ensure your anti-virus tools are up to date
- Monitor unusual backup volumes (locked-down files can call cause backup activity peaks because the file names are often modified)
- In the event of an attack, isolate the infected machine and ascertain which cryptovirus is the cause. Where possible, use tools to automatically or manually remove the virus and prevent propagation to other machines
Ensure continued activity – get your data back
- Have a well configured backup solution. One which means your DRP (Disaster Recovery Plan) will work efficiently and rapidly. If one or more machine is infected, often the only solution is to restore a backed up image to a healthy prior state. You need to know that this image is securely stored and uncompromised by any cyberattack.
