OpenSSL Gets Updated
OPENSSL, the web security layer at the center of the Heartbleed vulnerability, has been issued with a further nine critical patches.
While none are as serious as Heartbleed, patching is recommended for all users according to an advisory released today. The vulnerabilities stem from various security research teams around the web including Google, Logmein and Codenomicom, based on their reports during June and July of this year.
Among the more interesting fixes involves a flaw in the ClientHello message process. If a ClientHello message is badly fragmented, it is vulnerable to a man-in-the-middle attack which could be used to force the server to downgrade itself to the TLS 1.0 protocol, a fifteen year old and therefore pre-Heartbleed patch variant.
Other reports include memory leaks caused by denial of service attacks (DoS) and conversely, crashes caused by an attempt to free up the same portions of memory twice.
OpenSSL now has two full time coders as a result of investment by a consortium of Internet industry companies to form the Core Infrastructure Initiative, a not-for-profit group administered by the Linux Foundation. The Initiative was set up in the wake of Heartbleed, as the industry vowed to ensure such a large hole would never be left unplugged again.
While OpenSSL is used by a large number of encrypted sites, there are a number of forks of the project including LibreSSL and the recently launched Google BoringSSL.
Google recently announced that it would be lowering the page rankings of unencrypted pages in its search results as an added security measure.
Many Websites Still Exposed
The world’s top 1,000 websites have been updated to protect their servers against the “Heartbleed” vulnerability, but up to 2% of the top million remained unprotected as of last week, according to a California security firm.
On Thursday, Menifee, Calif.-based Sucuri Security scanned the top 1 million websites as ranked by Alexa Internet, a subsidiary of Amazon that collects Web traffic data.
Of the top 1,000 Alexa sites, all were either immune or had been patched with the newest OpenSSL libraries, confirmed Daniel Cid, Sucuri’s chief technology officer, in a Sunday email.
Heartbleed, the nickname for the flaw in OpenSSL, an open-source cryptographic library that enables SSL (Secure Sockets Layer) or TLS (Transport Security Layer) encryption, was discovered independently by Neel Mehta, a Google security engineer, and researchers from security firm Codenomicon earlier this month.
The bug had been introduced in OpenSSL in late 2011.
Because of OpenSSL’s widespread use by websites — many relied on it to encrypt traffic between their servers and customers — and the very stealthy nature of its exploit, security experts worried that cyber criminals either had, or could, capture usernames, passwords,\ and even encryption keys used by site servers.
The OpenSSL project issued a patch for the bug on April 7, setting off a rush to patch the software on servers and in some client operating systems.
The vast majority of vulnerable servers had been patched as of April 17, Sucuri said in a blog postthat day.
While all of the top 1,000 sites ranked by Alexa were immune to the exploit by then, as Sucuri went down the list and scanned smaller sites, it found an increasing number still vulnerable. Of the top 10,000, 0.53% were vulnerable, as were 1.5% of the top 100,000 and 2% of the top 1 million.
Other scans found similar percentages of websites open to attack: On Friday, San Diego-based Websense said about 1.6% of the top 50,000 sites as ranked by Alexa remained vulnerable.
Since it’s conceivable that some sites’ encryption keys have been compromised, security experts urged website owners to obtain new SSL certificates and keys, and advised users to be wary of browsing to sites that had not done so.
Sucuri’s scan did not examine sites to see whether they had been reissued new certificates, but Cid said that another swing through the Web, perhaps this week, would. “I bet the results will be much much worse on that one,” Cid said.
Do You Trust Data-recovery Providers?
Comments Off on Do You Trust Data-recovery Providers?
Data-recovery service providers are tasked with saving important data for you when something goes wrong — a drive crashes or storage device is dropped, and no backup is available. But do you trust them with the important data you let them recover or could they actually be a source for a data breach?
A survey of 769 IT professionals published this week finds those surveyed need to find out more about the third-party data-recovery services their organizations use. For example, according to the survey, 67% felt that encryption they had in place protected their organizations from data loss or theft during the data recovery process. But encryption keys are often handed over to the third-party data recovery service provider as part of the process, according to the study done by Ponemon Institute.
Ponemon’s “Trends in Security of Data Recovery Operations” report says of the 87% of survey respondents who said their organization had at least one data breach in the past two years, “21% say the breach occurred when a drive was in the possession of a third-party data service provider.”
