CL0P Targets PwC in Global Cyber Attack


PwC Australia is a well-known member of the global PwC network, offering professional services in audit, assurance, consulting, and tax. Known for their robust security measures and commitment to data privacy, they have, however, become the latest victim of a global cyber threat. 

The Broadening Net of Russian Cybercriminals 

The perpetrator of this cybercrime is the notorious Russian hacker group, CL0P. PwC Australia is their latest target, joining a growing list of international corporations succumbing to their ransomware attacks. 

Unmasking the Weakest Link: MOVEit 

So, how did CL0P manage to breach PwC’s defences? They exploited a vulnerability in a software platform named MOVEit. This platform, trusted by companies to transfer sensitive data securely, unfortunately, became the open door for hackers to grab valuable information. 

Repercussions of the PwC Cyber Attack Felt Globally 

This security breach isn’t confined to Australia’s shores. The US Cybersecurity and Infrastructure Security Agency (CISA) has reported that multiple US departments were similarly affected. Even in the UK, well-known organisations, including the BBC, Shell, and British Airways, have found themselves in the same cyber predicament. 

The connection to PwC was first hinted by the Australian Financial Review. PwC later confirmed their use of MOVEit, which was compromised during the attack. 

Immediate Response to the PwC Cyber Attack 

In the face of this cyberattack, PwC’s internal IT network remains untouched. The firm was quick to stop using the vulnerable platform and promptly launched an internal investigation to understand the full extent of the PwC cyber attack. 

Engaging Clients in the Aftermath of the Attack 

As a sign of their ongoing commitment to transparency, PwC has been proactively communicating with their clients affected by the incident, offering reassurance during these critical times. 

The PwC Cyber Attack: A Call to Action 

The need for companies to stay informed is essential, not just for themselves but for their customers too. Digging into resources like our Cybersecurity Guide can provide valuable insights into these risks. It’s also vital to develop and maintain a Cyber Security Strategy to pre-empt and combat these threats before an incident occurs. Let’s shift the focus from reactive measures to preventive ones; cybersecurity is no longer optional, it’s a business necessity.
