Google Chrome to Distrust Symantec SSLs for Mis-issuing 30,000 EV Certificates

The Hacker News - 1 hodina 55 min zpět
Google announced its plans to punish Symantec by gradually distrusting its SSL certificates after the company was caught improperly issuing 30,000 Extended Validation (EV) certificates over the past few years. The Extended Validation (EV) status of all certificates issued by Symantec-owned certificate authorities will no longer be recognized by the Chrome browser for at least a year until

Google takes Symantec to the woodshed for mis-issuing 30,000 HTTPS certs [updated]

In a severe rebuke of one of the biggest suppliers of HTTPS credentials, Google Chrome developers announced plans to drastically restrict transport layer security certificates sold by Symantec-owned issuers following the discovery they have allegedly mis-issued more than 30,000 certificates.

Effective immediately, Chrome plans to stop recognizing the extended validation status of all certificates issued by Symantec-owned certificate authorities, Ryan Sleevi, a software engineer on the Google Chrome team, said Thursday in an online forum. Extended validation certificates are supposed to provide enhanced assurances of a site's authenticity by showing the name of the validated domain name holder in the address bar. Under the move announced by Sleevi, Chrome will immediately stop displaying that information for a period of at least a year. In effect, the certificates will be downgraded to less-secure domain-validated certificates.

More gradually, Google plans to update Chrome to effectively nullify all currently valid certificates issued by Symantec-owned CAs. With Symantec certificates representing more than 30 percent of the Internet's valid certificates by volume in 2015, the move has the potential to prevent millions of Chrome users from being able to access large numbers of sites. What's more, Sleevi cited Firefox data that showed Symantec-issued certificates are responsible for 42 percent of all certificate validations. To minimize the chances of disruption, Chrome will stagger the mass nullification in a way that requires they be replaced over time. To do this, Chrome will gradually decrease the "maximum age" of Symantec-issued certificates over a series of releases. Chrome 59 will limit the expiration to no more than 33 months after they were issued. By Chrome 64, validity would be limited to nine months.

New WikiLeaks dump: The CIA built Thunderbolt exploit, implants to target Macs

WikiLeaks today dumped a smaller subset of documents from its "Vault 7" collection of files from a CIA software developer server. Yet again, these documents are more important from the perspective of WikiLeaks having them than for showing any revelatory content. The exploits detailed in these new files are for vulnerabilities that have largely been independently discovered and patched in the past. The files also reveal that the CIA likely built one of these tools after seeing a presentation on the exploits of Apple's EFI boot firmware at Black Hat in 2012.

The latest batch of files, dramatically named "DarkMatter" (after one of the tools described in the dump), consists of user manuals and other documentation for exploits targeting Apple MacBooks—including malware that leveraged a vulnerability in Apple's Thunderbolt interface uncovered by a researcher two years ago. Named "Sonic Screwdriver" after the ever-useful tool carried by the fictional Doctor of Dr. Who, the malware was stored on an ordinary Thunderbolt Ethernet adapter. It exploited the Thunderbolt interface to allow anyone with physical access to a MacBook to bypass password protection on firmware and install one of a series of Apple-specific CIA "implants."

The first (and only documented) version of Sonic Screwdriver was released in 2012. It worked only on MacBooks built between late 2011 and mid-2012, and the tool used a vulnerability in the firmware of those computers that allowed commands to be sent via the Thunderbolt adapter to change the "boot path" (the location of the files used to boot the computer). The change would allow a local attacker to boot the targeted MacBook from an external device to install malware that eavesdropped on the computer during normal use. Those implants included "DarkMatter," the predecessor to "QuarkMatter." (QuarkMatter is malware that was revealed in the previous WikiLeaks dump, and it infected the EFI partition of a MacBook's storage device.)
