Aussie sites affected by Heartbleed bug

A number of companies appear to have been affected by a serious security bug which has the potential to put private details at risk.

GE Money is recommending customers change their password, with a number of the company's Australian websites believed to be vulnerable to the Heartbleed bug, Fairfax reported.

Some of the affected sites include the Myer Visa Card and Myer Card websites, as well as the Coles Mastercard site.

Fairfax reported that the sites had since been patched, or were in the process of being patched, to protect against the security flaw.

However, users were still being urged to change their passwords as the bug could potentially have exposed customer financial details and log-ins to being extracted by hackers.

On its website, GE Money issued a warning that seemed linked to the Heartbleed saga.

"GE has taken precautions and steps to protect customer data from this [Heartbleed] threat and has no reason to believe that any customer data has been compromised," the message said.

"To change your password now, please click on the 'forgot your password' link…"

Myer said in a statement that it was "confident" customers had been protected from the security flaw.

"[GE] has taken the appropriate action to protect customer data in line with industry best practice," a Myer spokeswoman said.

Networking affected

It now appears that the Heartbleed security problem affects not just websites, but also the networking equipment that connects homes and businesses to the internet.

A defect in the security technology used by many websites and equipment makers has put millions of passwords, credit card numbers and other personal information at risk.

The extent of the damage caused by Heartbleed isn't known. The threat went undetected for more than two years, and it's difficult to tell if any attacks resulted from it because they don't leave behind distinct footprints.

But now that the threat is public, there's a good chance hackers will try to exploit it before fixes are in place, says Mike Weber, vice president of the information-technology audit and compliance firm Coalfire.

Two of the biggest makers of networking equipment, Cisco and Juniper, have acknowledged that some of their products contain the bug, but experts warn that the problem may extend to other companies as well as a range of internet-connected devices such as Blu-ray players.

"I think this is very concerning for many people," says Darren Hayes, professor of security and computer forensics at New York's Pace University.

"It's going to keep security professionals very busy over the coming weeks and months. Customers need to make sure they're getting the answers they need."

Here's a look at what consumers and businesses should know about Heartbleed and its effects on networking devices.

- How is networking equipment affected?

Just like websites, the software used to run some networking equipment - such as routers, switches and firewalls - also uses the variant of SSL/TLS known as OpenSSL. OpenSSL is the set of tools that has the Heartbleed vulnerability.

As with a website, hackers could potentially use the bug as a way to breach a system and gather and steal passwords and other sensitive information.

What can you do?

Security experts continue to advise people and businesses to change their passwords, but that won't be enough unless the company that created the software in question has put the needed fixes in place.

When it comes to devices, this could take a while. Although websites can be fixed relatively quickly by installing a software update, device makers will have to check each product to see if it needs to be fixed.

Both Cisco Systems and Juniper Networks continue to advise customers through their websites on which product is still vulnerable, fixed and unaffected. Owners may need to install software updates for products that are "fixed."

Hayes praises Cisco and Juniper for being upfront with customers. He cautions, though, that many other companies make similar products that likely have the bug, too, but haven't come forward to say so.

As a result, businesses and consumers need to check the websites for devices that they think could have problems. They must be diligent about installing any software updates they receive.

Weber says that while there are some checks companies can do to see if their networking equipment is safe, they're largely beholden to the device makers to let them know what's going on.

Companies also need to make sure that business partners with access to their systems aren't compromised as well.

- Are other devices at risk?

Hayes says the bug could potentially affect any home device that's connected to the internet, including something as simple as a wi-fi-enabled Blu-ray player.

He also points to recent advances in home automation, such as smart thermostats, security and lighting systems.

"We simply don't know the extent of this and it could affect those kinds of devices in the home," he says.
