Defend your organization before phishing campaigns are even launched by finding adversary pre-attack infrastructure. In this post, we provide a few tips for finding fraudulent domains in Censys.
As CWMP is one of most common protocol across the Internet, we explored the security of the protocol and what kind of risks it poses. Moreover, are there any real risks for the corporate world or is this just a consumer technology problem?
We recently started scanning for IPMI devices in Censys so that administrators can search for them and prioritize migrating them to a private network.
Magecart was the malware behind the British Airways and Ticketmaster data breaches a few years back and, unfortunately, it’s still alive and well. Here's how to hunt for Magecart using Censys.
We added data for remote desktop protocol (RDP) and virtual network computing (VNC) to Censys. Now you can search for any RDP or VNC servers that are online and tied to your organization and ensure that they’re locked down appropriately.
Today, we’re going to show you how you might look for suspicious-looking Apache Tomcat servers and either secure them or take them offline to prevent exploitation.
Censys results now include Internet Printing Protocol (IPP), which allows anyone to get a quick read of how many printers are connected to the Internet and locate any printers their organization may have inadvertently exposed to the public
Oracle recently released a critical patch for their Database Server product. This post explains how to find servers on the Internet that are affected by this vulnerability.
To help organizations investigate and monitor whether they’ve mistakenly exposed databases, we're adding scanning for four popular relational database servers: MySQL, PostgreSQL, Microsoft SQL Server, and Oracle Database.
On Tuesday, March 3, 2015, researchers announced a new SSL/TLS vulnerability called the FREAK attack. It allows an attacker to intercept HTTPS connections between vulnerable clients and servers and force them to use weakened encryption, which the attacker can break to steal or manipulate sensitive data. This site is dedicated to tracking the impact of the attack and helping users test whether they’re vulnerable.
On Tuesday, October 14, 2014, Google released details on the POODLE attack, a padding oracle attack that targets CBC-mode ciphers in SSLv3. The vulnerability allows an active MITM attacker to decrypt content transferred an SSLv3 connection. While secure connections primarily use TLS (the successor to SSL), most users were vulnerable because web browsers and servers will downgrade to SSLv3 if there are problems negotiating a TLS session.
The Heartbleed Bug is a vulnerability in the OpenSSL cryptographic library that allows attackers to invisibly read sensitive data from a web server. This potentially includes cryptographic keys, usernames, and passwords. More information and frequently asked questions can be found in the initial disclosure.
We report the results of a large-scale measurement study of the HTTPS certificate ecosystem—the public-key infrastructure that underlies nearly all secure web communications. Using data collected by performing 110 Internet-wide scans over 14 months, we gain detailed and temporally fine-grained visibility into this otherwise opaque area of security-critical infrastructure.
