Watch out! Mass Cyber Attack outbreak – WannaCry Ransomware

Posted May 15, 2017

Global cyber attack hits companies in over 100 countries. First case in Australia has been reported. Find out more about the ransomware and how to protect your business.

By Bremmar Team

Over the weekend there was a large scale Crypto Attack that targeted older Windows-based systems and infected various enterprises in all industries around the world. The cyber attack launched on Friday, 12th of May, has infected thousands of computers in over 104 countries and the first case in Australia has been reported.

The attackers trick victims into opening malicious malware attachments to spam emails. Once opened, the emails release the WannaCry ransomware which targets and encrypts 176 file types and infects database, multimedia and archive files.

Affected companies have to pay to recover files and are given a seven-day limit before the affected files are deleted.

WannaCry Ransomware

Bremmar actions

All Bremmar client computers that are within Microsoft support have been protected based on Microsoft’s advice and we are continuously monitoring for further protection measures. Clients with Webroot or Trend installed have been protected as well as clients using GatewayAV with a SonicWall.

We have also taken an extra technical step and disabled all SMB V1, a protocol that can potentially be exploited, across all our client base. We will also be working with clients with Windows XP machines (older and unsupported machines) to assist in getting their machines secured.

What Bremmar recommends

Even though the attacks have been somewhat controlled and are “dying off”, be extra cautious with your emails and don’t open anything you are unsure of.

If you are a client and are in any doubt as to the legitimacy of any emails you receive, the best method of protection is to not open attachments and contact your support team by phone or simply forward the email to your Bremmar Support Team address and they can review for safety. If you are not a client and would like to discuss your business security, please contact us on 1300 991 351.

We also strongly recommend that you forward this blog and information to your staff.
