Ransomware Attacks up 15 per cent, says New ACSC Cyber Threat Report

Ransomware up 15 per cent

The Australian Cyber Security Centre's Annual Cyber Threat Report finds ransomware remains one of the most disruptive threats to Australian organisations.

The report highlights the key cyber threats affecting Australian systems and networks and uses trend analysis to describe the nature, scale, scope and impact of malicious cyber activity affecting Australian networks.  With over 67,500 reports of cybercrime received in the 2020–21 financial year alone, sophisticated ransomware attacks were alarmingly found to be on the rise.

Some quick facts from the report...

  • Ransomware cybercrime reports increased by 15 per cent.
  • Nearly 500 ransomware cybercrime reports were received which categorised the type of attack as “the most serious cybercrime threat due to its high financial impact and disruptive impacts to victims and the wider community".
  • An average of more than one ransomware cybercrime report was received every day.

With the impact of ransomware attacks deemed as "in the realm of catastrophic" by Australian Signals Directors (ASD) Director-General, Rachel Noble, we urge all businesses to seek support to ensure their cyber defences are prepared for potential ransomware attacks.


Support to combat Ransomware from the Australian Government

Assistant Minister for Defence, the Hon Andrew Hastie MP, says the Government is tackling cybercriminals head-on to support Australian organisations and individuals from cyber compromise.

“The government is taking action, and we have introduced legislations to ensure that in the event of a large-scale cyber attack on our critical infrastructure, our cyber and law enforcement agencies are empowered to provide greater and more immediate support to the victims,” Mr Hastie said.


How to protect your business from Ransomware

Assistant Minister Hastie goes on to note that "ransomware is one of the most damaging types of cyberattacks, which can have severe and long-lasting impacts on Australian organisations and their operations. But prevention is better than cure, and with cyber security, the best offence is often a strong defence."

The ACSC has published a ransomware Prevention and Protection Guide, with steps on how businesses can protect themselves from ransomware, including:

  • Updating your devices and turning on automatic updates.
  • Turning on Multi-Factor Authentication.
  • Setting up and performing regular back ups.
  • Implementing Access Controls.
  • Turning on Ransomware protection.
  • Preparing a cyber emergency (also known as Disaster Recovery) plan.

ACSC advice on payment of ransom demands

When US security firm Crowdstrike surveyed senior Australian IT professionals for its 2020 Global Security Attitude Survey, it found 33 per cent of those who admitted to falling victim to a ransomware attack said they paid the ransom.

The ACSC advises against paying a ransom. Doing so does not guarantee a victim’s files will be restored, nor does it prevent the publication of any stolen data, or it being sold for use in other crimes. Along with increasing the likelihood of a victim being targeted again, each ransom payment also bolsters the viability of the ransomware market and puts other Australian organisations at greater risk.

Irrespective of the decision to pay a ransom, all victims are strongly encouraged to report ransomware-related cybercrime and cyber security incidents to the ACSC. Sharing technical and contextual information about an incident helps to protect other potential victims, supports efforts to disrupt criminal operations and enables the ACSC to implement measures to reduce ransomware targeting against Australia.
