Watch a Homemade Robot Crack a Safe in Just 15 Minutes - 21 Červenec, 2017 - 11:05 Last Christmas, Nathan Seidle's wife gave him a second-hand safe she'd found on Craigslist. It was, at first glance, a strange gift. The couple already owned the same model, a $120 SentrySafe combination fire safe they'd bought from Home Depot. But this one, his wife explained, had a particular feature: The original owner had locked it and forgotten the combination. Her challenge to Seidle: Open it.

Švédská Bezpečnostní policie (Säpo) prověřuje možný únik dat, s nimiž nakládají švédské vládní úřady.

Data se měla dostat mimo jiné do České republiky, konkrétně k pracovníkům české pobočky společnosti IBM, která pro švédský úřad zajišťovala IT služby.

Google drops the boom on WoSign, StartCom certs for good

Ars Technica - 20 Červenec, 2017 - 23:57

Last August, after being alerted by GitHub's security team that the certificate authority WoSign had errantly issued a certificate for a GitHub domain to someone other than GitHub, Google began an investigation in collaboration with the Mozilla Foundation and a group of security professionals into the company's certificate issuance practices. The investigation uncovered a pattern of bad practices at WoSign and its subsidiary StartCom dating back to the spring of 2015. As a result, Google moved last October to begin distrusting new certificates issued by the two companies, stating "Google has determined that two CAs, WoSign and StartCom, have not maintained the high standards expected of CAs and will no longer be trusted by Google Chrome."

WoSign (based in Shenzen, China) and StartCom (based in Eliat, Israel) are among the few low-cost certificate providers who've offered wildcard certificates. StartCom's StartSSL offers free Class 1 certificates, and $60-per-year wildcard certificates—allowing the use of a single certificate on multiple subdomains with a single confirmation. This made the service wildly popular. But bugs in WoSign's software allowed a number of misregistrations of certificates. One bug allowed someone with control of a subdomain to claim control of the whole root domain for certificates. The investigation also found that WoSign was backdating the SSL certificates it issued to get around the deadline set for certificate authorities to stop issuing SHA-1 SSL certificates by January 1, 2016. WoSign continued to issue the less secure SHA-1 SSL certificates well into 2016.

Initially, Google only revoked trust for certificates issued after October 21, 2016. But over the past six months, Google has walked that revocation back further, only whitelisting certificates for domains from a list based on Alexa's top one million sites. But today, Google announced that it would phase out trust for all WoSign and StartCom certificates with the release of Chrome 61. That release, about to be released for beta testing, will be fully released in September.

Security Concerns Around Zombie Cloud Infrastructure

InfoSec Institute Resources - 20 Červenec, 2017 - 22:35

One of the most important benefits of the use of cloud instances over traditional network configurations is that one can be literally setup within seconds, by the click of a few buttons. This ability has dramatically reduced deployment times for test, model, and production systems. It also allows for great flexibility both from a technical […]

Final removal of trust in WoSign and StartCom Certificates

Google Security Blog - 20 Červenec, 2017 - 20:19
Posted by Andrew Whalley and Devon O'Brien, Chrome Security

As previously announced, Chrome has been in the process of removing trust from certificates issued by the CA WoSign and its subsidiary StartCom, as a result of several incidents not in keeping with the high standards expected of CAs.

We started the phase out in Chrome 56 by only trusting certificates issued prior to October 21st 2016, and subsequently restricted trust to a set of whitelisted hostnames based on the Alexa Top 1M. We have been reducing the size of the whitelist over the course of several Chrome releases.

Beginning with Chrome 61, the whitelist will be removed, resulting in full distrust of the existing WoSign and StartCom root certificates and all certificates they have issued.

Based on the Chromium Development Calendar, this change is visible in the Chrome Dev channel now, the Chrome Beta channel around late July 2017, and will be released to Stable around mid September 2017.

Sites still using StartCom or WoSign-issued certificates should consider replacing these certificates as a matter of urgency to minimize disruption for Chrome users.

FCC has no documentation of DDoS attack that hit net neutrality comments

The US Federal Communications Commission says it has no written analysis of DDoS attacks that hit the commission's net neutrality comment system in May.

In its response to a Freedom of Information Act (FoIA) request filed by Gizmodo, the FCC said its analysis of DDoS attacks "stemmed from real time observation and feedback by Commission IT staff and did not result in written documentation." Gizmodo had asked for a copy of any records related to the FCC analysis that concluded DDoS attacks had taken place. Because there was no "written documentation," the FCC provided no documents in response to this portion of the Gizmodo FoIA request.

The FCC also declined to release 209 pages of records, citing several exemptions to the FoIA law. For example, publication of documents related to "staffing decisions made by Commission supervisors, draft talking points, staff summaries of congressional letters, and policy suggestions from staff" could "harm the Commission’s deliberative processes," the FCC said. "Release of this information would chill deliberations within the Commission and impede the candid exchange of ideas."
