Yahoo! Xtra hack: Telecom warns customers to change passwords, beware scammers
Campbell Live talks to Martin Cocker
Cyber security awareness surged amongst many New Zealanders this week after the media reported widespread spam and phishing emails affecting Yahoo! Xtra account holders.

Visitors to the How can I security check my computer? page on the NetSafe website surged by more than 8000% with 1500+ people reviewing our advice since Monday and traffic to Security Central quadrupling over the week.

There are lots of opinions online on how the hack occurred and what ramifications it may have for people who have had their email accounts compromised.

NetSafe would encourage all YahooXtra users to follow Telecom advice and change their password (www.telecom.co.nz/changepassword).

We would also encourage you to take this opportunity to review your computer security in general, clearing out old email storage, changing passwords on important accounts and running scans on your machines and patching any holes in software or helper apps.

2012 Incident Report: Is cyber crime on the rise in NZ?
NCSC 2012 Incident Reports
The National Cyber Security Centre (NCSC) - the government body which helps agencies and power companies defend against cyber threats - published its 2012 Incident Summary (PDF) yesterday and saw a significant increase in the number of reported attacks against New Zealand government agencies, critical national infrastructure, and private sector organisations over the year.
 
GCSB Director Ian Fletcher says 134 threats were reported with "at least three serious attacks every week".
 
Morning Report covered the figures this morning with some commentators saying that NZ corporates and home users need to make more effort to protect against cyber threats.

In light of the media attention this week, do you believe New Zealand is a soft target increasingly targeted by cyber criminals?

Vote now on our poll or send us your feedback by email.

Our last poll in 2012 asked What do you think will be the biggest computer security threat in 2013? 25% of respondents chose targeted social engineering and believed spear phishing or whaling was the biggest threat to watch out for this year.
