If you are a Singtel user and get an e-mail informing you to download your latest bill, check the source carefully before taking action or you might become the victim of a phishing scam.

Phishing is an attempt to obtain sensitive information such as passwords, often for malicious reasons, by disguising as a trustworthy entity.

In response to queries from The Straits Times, Singtel yesterday said it was aware of e-mails claiming to be from the telco and "asking recipients to access a website link to view and download their Singtel bill".

"These are phishing e-mails and are not from Singtel."

Once it was informed of the malicious e-mails, it took "prompt action to take down the malicious sites linked to these e-mails and to block them".

Singtel advises recipients of suspicious e-mails "not to respond to or click on any links in the message" and to delete such e-mails immediately.

ST understands that there were e-mails sent on Monday and Tuesday from noreply- s2@singtel.com.sg with the header "Your Sigtel (sic) bill is now available for download".

Singtel advised that phishing and fraudulent e-mails can be identified by misleading e-mail and website addresses as well as spelling mistakes and requests for personal information.
