Phishing emails attempt to obtain personal information from recipients, including passwords and bank account details, by pretending to be from an organisation.

A statement on the company’s website said that while the ISP attempts to filter out scam emails, but stopping everything is not possible.

“We have become aware of an increased number of phishing emails targeting email addresses @dcsi.net.au and @sympac.com.au,” the statement read.

“Although our servers filter out the majority of such messages and what you see in your inbox is just the tip of the iceberg, we can never hope to eliminate 100% of them.

“The best weapon is to be informed so that you know what’s real and what’s not.”

The statement said phishing emails were easy to spot.

“It’s actually fairly simple to spot most phishing emails.”

“Just remember this rule: DCSI will never ask you to provide your password via email, or by clicking on a link that is not on the dcsi.net.au domain.”
