Ransomware

What You Can Do

Ransomware is a type of malware that prevents the victim from accessing many files on their computer and on any fileshares they are connected to.

It is usually downloaded via a link in an email, on a website or on social media. Once downloaded, it encrypts all data files on the computer and a blocking screen then appears, demanding a ransom payment to allow the files to be released

 

  • DO NOT click links in suspicious emails or download unsolicited email attachments.
  • If you receive an email from a known sender, but with an unusual link or attachment, contact them first to confirm the legitimacy of the email.
  • If you receive a suspicious email in relation to your Bank of Ireland accounts, forward it as an attachment to 365security@boi.com immediately.
  • Be careful when accessing websites; do not click on advertisements as they could contain malicious software.
  • Ensure your anti-virus software is up to date.
  • Always run your computer or network on the most up to date version of the operating system.

Protect yourself

In addition to the general guidance above, you should take the following step to protect yourself:

  • Set your Windows Update settings to automatically update (and apply patches) as early as possible.

Protect your business

In addition to the general guidance above, you should take the following steps to protect your business:

  • Apply security patches as soon as possible after they become available.
  • Back up your data. You can’t be held to ransom if you hold your data somewhere else.
  • Review and restrict accesses to your technology on a needs basis.
  • Ensure you have a firewall enabled on your technology.

If you are affected

If you think you have been the victim of a ransomware attack and your data files have become infected, the general advice from law enforcement agencies is not to pay the ransom.

It is also advised that you disconnect infected computers from your business network immediately to stop the spread of infection to other computers in your network.

Contact your security service provider if you have one, or seek professional advice from a security service provider.
