A secure captive portal browser with automatic DNS detection
Captive portals are the worst. Flaky detection. The OS and browser try to detect these annoying network features but fail quite often, leaving you with broken connections. DID YOU KNOW that probe-based captive portal detection really doesnt work very well, with 30% FP and 30% FN rate in Chrome? -...
Modern Network Coverage and Container Security in InsightVM
For a long time, the concept of "infrastructure" remained relatively unchanged: Firewalls, routers, servers, desktops, and so on make up the majority of your network. Yet over the last few years, the tides have begun to shift. Virtualization is now ubiquitous, giving employees tremendous leeway i...

DEBIAN-CVE-2017-3730
In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack...
Invalid Curve Attack
github.com/square/go-jose is vulnerable to invalid curve attacks. These attacks are possible when using key agreement with Elliptic Curve Diffie-Hellman Ephemeral Static ECDH-ES, allowing attackers to recover the private secret key...
Reliability and scalability improvements in TCP/IP for Windows 8.1 and Windows Server 2012 R2
Reliability and scalability improvements in TCP/IP for Windows 8.1 and Windows Server 2012 R2 Summary This article describes various network and computer issues that occur when TCP ephemeral ports are exhausted in Windows 8.1 or Windows Server 2012 R2. An update is available to fix these issues...
CVE-2016-6882
MatrixSSL before 3.8.7, when the DHERSA based cipher suite is supported, makes it easier for remote attackers to obtain RSA private key information by conducting a Lenstra side-channel attack...
Denial Of Service (DoS)
OpenSSL is vulnerable to denial of service DoS attacks. These attacks are possible when the client authentication and ephemeral Diffie-Hellman ciphersuite are enabled. They can be triggered through the use of a ClientKeyExchange with a length of zero...

Congressional Group Says Encryption Backdoors Are a Bad Idea
The Congressional Encryption Working Group released its year-end report that concluded that encryption backdoors do more harm than good. The 12-page report said that “any measure that weakens encryption works against the national interest.” The bipartisan congressional panel recommended that the...
Researchers Demonstrated How NSA Broke Trillions of Encrypted Connections
In the year 2014, we came to know about the NSA's ability to break Trillions of encrypted connections by exploiting common implementations of the Diffie-Hellman key exchange algorithm – thanks to classified documents leaked by ex-NSA employee Edward Snowden. At that time, computer scientists and...

openssl: only allow ephemeral RSA keys in export ciphersuites (FREAK)
It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method...
The vulnerability of the console-based graphic editor ImageMagick, which allows a hacker to delete any files they want
The vulnerability of the EPHEMERAL encoder in the console-based ImageMagick graphics editor is related to lack of access control. Exploiting this vulnerability allows a malicious actor to delete arbitrary files using a specially crafted image...
