DNS Infrastructure Hijacking Campaign

Jan 10, 2019

Original release date: January 10, 2019 The National Cybersecurity and Communications Integration Center (NCCIC), part of the Cybersecurity and Infrastructure Security Agency (CISA), is aware of a global Domain Name System (DNS) infrastructure hijacking campaign. Using compromised credentials, an attacker can modify the location to which an organization’s domain name resources resolves. This enables the attacker to redirect user traffic to attacker-controlled infrastructure and obtain valid encryption certificates for an organization’s domain names, enabling man-in-the-middle attacks.NCCIC encourages administrators to review FireEye’s blog on global DNS infrastructure hijacking for more information. Additionally, NCCIC recommends the following best practices to help safeguard networks against this threat:Implement multifactor authentication on domain registrar accounts, or on other systems used to modify DNS records.Verify that DNS infrastructure (second-level domains, sub-domains, and related resource records) points to the correct Internet Protocol addresses or hostnames.Search for encryption certificates related to domains and revoke any fraudulently requested certificates.

Securing New Devices

Dec 28, 2018

Original release date: December 28, 2018 During the holidays, internet-connected devices also known as Internet of Things (IoT) are often popular gifts—such as smart TVs, watches, toys, phones, and tablets. This technology provides a level of convenience to our lives, but it requires that we share more information than ever. The security of this information, and the security of these devices, is not always guaranteed.The National Cybersecurity and Communications Integration Center (NCCIC), part of the Cybersecurity and Infrastructure Security Agency (CISA), recommends these important steps you should consider to make your Internet of Things more secure:Evaluate your security settings. Most devices offer a variety of features that you can tailor to meet your needs and requirements. Enabling certain features to increase convenience or functionality may leave you more vulnerable to being attacked. It is important to examine the settings, particularly security settings, and select options that meet your needs without putting you at increased risk. If you install a patch or a new version of software, or if you become aware of something that might affect your device, reevaluate your settings to make sure they are still appropriate. See Good Security Habits for more information.Ensure you have up-to-date software. When manufacturers become aware of vulnerabilities in their products, they often issue patches to fix the problem. Patches are software updates that fix a particular issue or vulnerability within your device’s software. Make sure to apply relevant patches as soon as possible to protect your devices. See Understanding Patches for more information.Connect carefully. Once your device is connected to the Internet, it’s also connected to millions of other computers, which could allow attackers access to your device. Consider whether continuous connectivity to the Internet is needed. See Securing Your Home Network for more information.Use strong passwords. Passwords are a common form of authentication and are often the only barrier between you and your personal information. Some Internet-enabled devices are configured with default passwords to simplify setup. These default passwords are easily found online, so they don't provide any protection. Choose strong passwords to help secure your device. See Choosing and Protecting Passwords for more information. This product is provided subject to this Notification and this Privacy & Use policy.
