Just seven of the companies that are part of the ASX100 are fully compliant with DMARC, even though this is one of the more effective ways of avoiding email and domain fraud, the email security firm Proofpoint says.
These seven firms were blocking fraudulent emails before the fact as they should.
In all, only 39% had published a DMARC record, the company said in figures released on Wednesday.
According to Wikipedia, DMARC or domain-based message authentication, reporting and conformance "is an email-validation system designed to detect and prevent email spoofing.
It is intended to combat certain techniques often used in phishing and email spam, such as emails with forged sender addresses that appear to originate from legitimate organisations".
Sixty percent of the top 10 in the ASX100 had a DMARC record while of those that had started to deploy DMARC, a quarter were from the financial sector.
Of the top five banks, four had deployed DMARC, Proofpoint said.
Among Australian Government departments, seven out of 18 or 38% had published a DMARC record.
"Only finance.gov.au has moved to reject since the last time we analysed the data back in October 2017. All deployments are in monitor mode," Proofpoint global chief executive Gary Steele said.
Five out of the seven agencies on the DMARC journey were not using a third-party vendor for their implementation and their progress had been stagnant for the last nine months.LEARN HOW TO REDUCE YOUR RISK OF A CYBER ATTACK
