And the report from security firm Trend Micro also reveals that business email compromise (BEC) remains a major threat, with Australian businesses encountering more than a quarter – or 27.2% - of the total number of BEC attempts globally.
Trend Micro also report that there has been a worldwide surge in fileless attacks designed to disguise malicious activity, with detections of the threat up 265% compared to the first half of 2018.
The security firm says the rise in fileless attacks confirm many of its predictions of last year that attackers are working smarter to target businesses and environments that will produce the greatest return on investment.
“The attacks aren’t necessarily more frequent, but attackers are using intentional and targeted attacks to maximise profitability through taking advantage of people, processes, and technology.
“Take ransomware for example. When it’s deployed as part of a strategic attack on a vulnerable industry, a business might find itself powerless. This is when a technology partner that can combine human expertise with advanced security technologies to better detect, correlate, respond to, and remediate threats is most needed.”
According to Trend Micro, along with the growth in fileless threats in the first half of the year, attackers are increasingly deploying threats that aren’t visible to traditional security filters, as they can be executed in a system’s memory, reside in the registry, or abuse legitimate tools.
On a global scale, cryptomining malware remained the most detected threat with attackers increasingly deploying these threats on servers and in cloud environments, Trend Micro reveals.
Substantiating another of its predictions, Trend Micro says the number of routers involved in possible inbound attacks jumped 64% compared to the first half of 2018, with more Mirai variants searching for exposed devices.
And additionally, digital extortion schemes soared by 319% from the second half of 2018 - which Trend Micro says aligns with previous projections – while ransomware-related files, emails and URLs also grew 77% over the same period.
In total, Trend Micro blocked more than 26.8 billion threats in the first half of 2019, over 6 billion more than the same period last year.
Trend Micro says that 91% of these threats entered the corporate network via email, and mitigating these advanced threats requires smart defence-in-depth that can correlate data from across gateways, networks, servers and endpoints to best identify and stop attacks.
