The worldwide cyber-attack that brought
the NHS to its knees recently has definitely reiterated the threats faced by
businesses working in the modern digital environment.
The much publicised attack made
use of hacking tools to spread ransomware known as ‘WannaCry’. Not only did it
affect the NHS, but also global shipping outfit FedEx as well as more than
300,000 computers over 150 countries. Cybersecurity company F-Secure described
it as ‘the biggest ransomware outbreak in history’.
WannaCry made its way in through
emails that had been designed to trick the recipient into opening attachments primed
to release malware onto their system. Affected computers locked up files and
encrypted them, making them inaccessible to users unless they made a payment
using bitcoin. The trouble was, even if payment was forthcoming, there was no
real guarantee that access would be restored.
Microsoft released a patch in
March this year to fix a vulnerability that WannaCry exploited. However, not
everyone installs updates as soon as they become available, which left the
vulnerability exposed.
When it came to casualties of the
attack, the NHS came off worst. Hospitals and GP surgeries nationwide fell into
chaos with patient systems and medical records inaccessible. Other victims
included FedEx, Portugal Telecom and Spain’s Telefonica together with German
railway Deutsche Bahn.
How to Protect Against Cyber Attacks
It is essential to make sure all
software is kept updated. The updates that are made available usually
incorporate security patches, which means ignoring them or putting them off is
very risky.
Vigilance with emails is also
crucial. Looking out for suspicious messages that contain links or attachments
should be the norm right across the organisation, with strict parameters set as
to what to do and what not to do. As well as employees, make sure outsourced
staff and subcontractors are aware of your rules about links and attachments in
emails and that they know the risks of downloading programs, apps and software
from unofficial or non-secured sources.
Dealing with Cyber Attack Risks
Cyber risk insurance is an astute
choice for any business. It is designed to restore an organisation to its
complete operational status as quickly as possible following an attack.
Cyber risk insurance covers the
policy holder for malicious attacks, cyber extortion, denial of service and
human-error data breaches. Depending on the small print, it can provide legal
guidance, business interruption cover, public relations advice, IT forensics,
data restoration and cover for lost profits.
Hackers are finding new inroads
on a daily basis. Make sure your business is safe and covered for this very
real risk. If you need practical advice, you can always talk to your local bookkeepers.
