Cybercrime reports in Australia are now being lodged every 8 minutes
With over 67,500 reports of cybercrime received during the 2020-21 financial year, theย ACSC Annual Cyber Threat Report 2020-21ย found that attack volumes increased nearly 13 per cent compared with theย previous yearย when the agency received one report every 10 minutes.
Not only were there more incidents, but more were classified as โsubstantialโ in their impact โ reflecting an increase in attacks on larger organisations and their bigger consequences for victims.
โMalicious cybercriminals are escalating their attacks on Australians,โ Andrew Hastie, Assistant Minister for Defence,ย saidย as the new report was launched.
โWe need all Australians to be vigilantโฆ [and] on guard against malicious emails and texts.โ
Reflecting theย surge of cybercrimeย during the pandemic, over 1,500 COVID-related reports were lodged per month with the ACSC โ which also provided domestic and foreign advice and assistance for more than 1,630 cyber incidents as nation-state actors searched for โsensitive information about Australiaโs response to COVIDโ.
โThe increasing frequency of cybercriminal activity is compounded by the increased complexity and sophistication of their operations,โ the report warns, flagging the development of off-the-shelfย cybercrime toolsย โ such asย ransomware-as-a-serviceย โ that had simplified cybercrime for โa growing number of malicious actors without significant technical expertise and without significant financial investment.โ
Sophisticated or not, those malicious actors were moving โat speed and scaleโ, the ACSC said, oftenย exploiting new vulnerabilitiesย within hours of theirย public disclosure.
โWe know some of the tried and true methods cybercriminals use to target organisations,โ Tenable staff research engineer Satnam Narang said in response to the ACSC update, โ[yet] despite this knowledge being widely discussed, we continue to witness cybercriminals successfully utilising these tactics.โ
โReadily available proof-of-concept exploit code typically provided for defenders are being routinely incorporated into toolkits by cybercriminals and used against vulnerable systems.โ
Attacks on key Australian infrastructure operations had increased dramatically over the past year, with one-quarter of incidents reported to the ACSC related to โsignificant targetingโ ofย critical Australian infrastructureย or services.
While the consequences of supply-chain attacks were โnot as severeโ for Australian companies as last yearโsย SolarWinds compromise, the ACSC said, โa number of organisations were forced to take mitigation actions to prevent more serious impacts to their networks.โ
โThe threat from supply chain compromises remains high.โ
Also problematic is business email compromise (BEC) โ a type of email attack in which cybercriminalsย pretend to be trusted executivesย orย business partnersย to manipulate employees into wiring them money.
The average BEC victim lost over $50,600 during 2020-21โ representing a more than 50 per cent increase over the previous year โ and the ACSC warned of worse damage to come as โthese groups have developed enhanced, streamlined methods for targeting Australiansโ.
The new figures are the latest in a parade of statistics confirming that cybercriminal activityย surged during 2020ย and shows no signs of stopping this year, with Australia one of the worldโsย most-hacked countriesย and costsย spirallingย into the millions per incident.
Compromisesย of Australianย hospitalsย were of particular concern, given their importance in the ongoing national COVID response.
โBy targeting bigger businesses and essential services, the attackers are calculating that the victims canโt afford to be offline for any extended period and will pay the ransom just so they can continue operating as usual,โ noted Dale Heath, engineering manager with anti-ransomware firm Rubrik ANZ.
โThese attacks are not going to stop anytime soon. In fact, quite the opposite. They will continue to evolve, becoming more sophisticated, and more disruptive as attackers aim to make recovery as difficult and costly as possible.โ
Preparedness is critical to minimising the impact of attacks, the ACSC said, citing the proactivity of Victoriaโs Department of Health in recovering after a ransomware attackย crippledย Victorian hospitals earlier this year.
โPrompt action by the health service, the use of advanced cyber security tools provided by the Department, and collaboration between the health service, government and contracted cyber security partners,โ the report notes, โsignificantly reduced the impact of the ransomware attack and the restoration time.โ
Hastie repeated a familiar refrain, exhorting Australians to fight attacks โ and the widespread exploitation of legitimate user credentials to execute them โ by taking โsimple cyber security stepsโ such as using strong passphrases, using two-factor authentication, updating software and devices, and maintaining regular data backups.
Yet there are signs authorities are tiring of offering the same old advice over and over, with new discussions this year considering whether to light a fire under company directors byย holding them personally responsibleย for cyber attacks.
โIf the definition of insanity is to do the same thing over and over and expect a different result, then government and business must acknowledge that a completely new approach to protecting and verifying identity credentials online is required,โ said H. Daniel Elbaum, chairman and co-CEO of Australian security firmย Veroguard.
With new technologies like AI, big data, analytics and virtual reality set to โadd further complexities and greater vulnerabilities to already stressed systems,โ he said, โprevention is better than detection and remediation โ which is always too late.
