What DNS abuse techniques are employed by cyber adversaries and which organizations can help incident responders and security teams detect, mitigate and prevent them? The DNS Abuse Techniques Matrix published by FIRST provides answers. Among its many special interest groups is the DNS Abuse SIG, which compiled the DNS Abuse Techniques Matrix.
The Internet Systems Consortium has released patches to address multiple security vulnerabilities in the Berkeley Internet Name Domain 9 Domain Name System software suite that could lead to a denial-of-service condition. "A remote attacker could exploit these vulnerabilities to potentially cause denial-of-service conditions and system failures," the U.S. Cybersecurity and Infrastructure Security Agency said in an advisory released Friday.
Test via a DNS server that was specially created to track and teach you about DNS traffic. By default, DNS requests include a single "Identification tag", which is referred to in the DNS data-format documentation simply as ID. Amazingly, despite having received numerous updates and suggested improvements over the years, the official internet RFC document that acts as the DNS specification is still RFC 1035, dating all the way back to November 1987, just over 35 years ago!
Threat actors associated with the Roaming Mantis attack campaign have been observed delivering an updated variant of their patent mobile malware known as Wroba to infiltrate Wi-Fi routers and undertake Domain Name System hijacking. Kaspersky, which carried out an analysis of the malicious artifact, said the feature is designed to target specific Wi-Fi routers located in South Korea.
The Roaming Mantis malware distribution campaign has updated its Android malware to include a DNS changer that modifies DNS settings on vulnerable WiFi routers to spread the infection to other devices. O/XLoader Android malware that detects vulnerable WiFi routers based on their model and changes their DNS. The malware then creates an HTTP request to hijack a vulnerable WiFi router's DNS settings, causing connected devices to be rerouted to malicious web pages hosting phishing forms or dropping Android malware.
When you are trying to get another layer of cyber protection that would not require a lot of resources, you are most likely choosing between a VPN service & a DNS Security solution. According to Cybernews, last year 20 million emails and other personal data like location & legal information were stolen via VPN. DNS Security Explained.
Russian retail chain 'DNS' disclosed yesterday that they suffered a data breach that exposed the personal information of customers and employees. While the firm has not provided details on what information was compromised, it clarified that the hackers didn't steal user passwords and payment card data, as that data isn't stored on their systems.
Akamai's security research team examined potentially compromised devices, discovering that 12.3% communicated with domains associated with malware or ransomware during Q2 2022. This Help Net Security video uncovers how malicious DNS traffic affects people on the other end of the internet connection.
Google on Tuesday officially announced support for DNS-over-HTTP/3 for Android devices as part of a Google Play system update designed to keep DNS queries private. To that end, Android smartphones running Android 11 and higher are expected to use DoH3 instead of DNS-over-TLS, which was incorporated into the mobile operating system with Android 9.0.
Google has added support for the DNS-over-HTTP/3 protocol on Android 11 and later to increase the privacy of DNS queries while providing better performance. Roid previously supported DNS-over-TLS for version 9 and later to bolster DNS query privacy, but this system inevitably slowed down DNS requests due to the encryption overhead. Moreover, DoT requires a complete renegotiation of the new connection when changing networks.
