'Heartbleed' computer bug threat spreads, but Singapore banks say they are unaffected

Reuters, AsiaOne | Friday, Apr 11, 2014

BOSTON - Hackers could crack email systems, security firewalls and possibly mobile phones through the "Heartbleed" computer bug, according to security experts who warned on Thursday that the risks extended beyond just Internet Web servers.

The widespread bug surfaced late on Monday, when it was disclosed that a pernicious flaw in a widely used Web encryption programme known as OpenSSL opened hundreds of thousands of websites to data theft. Developers rushed out patches to fix affected web servers when they disclosed the problem, which affected companies from Amazon.com Inc and Google Inc to Yahoo Inc.

Yet pieces of vulnerable OpenSSL code can be found inside plenty of other places, including email servers, ordinary PCs, phones and even security products such as firewalls. Developers of those products are scrambling to figure out whether they are vulnerable and patch them to keep their users safe.

"I am waiting for a patch," said Jeff Moss, a security adviser to the US Department of Homeland Security and founder of the Def Con hacking conference. Def Con's network uses an enterprise firewall from McAfee, which is owned by Intel Corp's security division.

He said he was frustrated because people had figured out that his email and Web traffic is vulnerable and posted about it on the Internet - but he can't take steps to remedy the problem until Intel releases a patch.

"Everybody is going through the exact same thing I'm going through, if you are going through a vendor fix," he said.

An Intel spokesman declined comment, referring Reuters to a company blog that said: "We understand this is a difficult time for businesses as they scramble to update multiple products from multiple vendors in the coming weeks. The McAfee products that use affected versions of OpenSSL are vulnerable and need to be updated."

It did not say when they would be released.

The Heartbleed vulnerability went undetected for about two years and can be exploited without leaving a trace, so experts and consumers fear attackers may have compromised large numbers of networks without their knowledge.

Companies and government agencies are now rushing to understand which products are vulnerable, then set priorities for fixing them. They are anxious because researchers have observed sophisticated hacking groups conducting scans of the Internet this week in search of vulnerable servers.

In Singapore, the Infocomm Development Authority (IDA) said no government websites and systems have been attacked. "Government agencies have been informed to adopt all necessary security measures for their websites and e-services. This includes the checking and fixing of vulnerabilities and software patching, where applicable," its spokesperson told The Straits Times.

Several financial institutions contacted by AsiaOne said that they are investigating the issue.

A DBS spokesperson said that it is "not affected by this vulnerability and [has] multiple layers of security in place", while Citibank told The Straits Times that it has "no reason to believe [its] customer-facing websites are susceptible to this vulnerability".
