In recent months, you’ve likely heard about DNS over HTTPS , also known as DNS 2.0 and DoH, which is a method that uses the HTTPS protocol to encrypt DNS requests, shielding their contents from malicious actors and others who might misuse such information. Ultimately, this DNS privacy upgrade has been a long time coming.
In that spirit, we put together this blog post to explain the different hacker types and methods they use against us. For even more tips from Webroot IT security experts Tyler Moffitt, Kelvin Murray, Grayson Milbourne, George Anderson and Jonathan Barnett, download the complete e-book on hacker personas. The post Who’s Hacking You?
An endpoint DNS solution could have stopped the Trojanized Orion version by refusing to resolve the domain names of the command-and-control servers, again disrupting the infection to the point that no real damage could be done. Together these numbers suggest a significant security threat for companies with remote workers.
Most security analysts do not wish to do this. Surely, someone must have written a blog or something more descriptive about this already,” they would say. However, the detection engine was really saying, “I suspect there is DNS tunnelling activity happening through your DNS server—just look at the volume.”.
For organizations with large footprint of remote employees, zero trust network access (ZTNA) prevents unauthorized access, contains breaches, and limits an attacker’s lateral movement on your network.

For a “normal” connection to a website, a Domian Name System (DNS) finds the IP address for the requested domain name. As I explained in the blogDNS hijacks: what to look for , DNS is the phonebook of the internet to the effect that the input is a name and the output is a number.
The problem here is that a secured, cost-effective, and efficient networkmust be developed to support remote operations at scale. Many enterprises have accelerated their use of Virtual Private Network (VPN) solutions to support remote workers during this pandemic. The makeup of SASE . But it much further.
The most popular lookup currently being seen in both PoCs and active exploitation is utilizing LDAP; however, other lookups such as RMI and DNS are also viable attack vectors. Going forward we plan to test variations of the exploit delivered using additional services such as DNS. We may update this document accordingly with results.
We looked at REvil, also known as Sodinokibi or Sodin, earlier in the year in a Threat Trends blog on DNSSecurity. In it we talked about how REvil/Sodinokibi compromised far more endpoints than Ryuk, but had far less DNS communication. Figure 1-DNS activity surrounding REvil/Sodinokibi.
It may be as simple as the deployment of antivirus plus backup and recovery applications for your end users, or a more complex approach with security operations center (SOC) tools or managed response solutions coupled with networksecurity tools such as DNS and Web filtering, network and endpoint firewalls, VPNs, backup and recovery and others.

In a blog post, the Qualys Research Team said that these vulnerabilities affect numerous organizations because an estimated 60% of internet servers run on Exim. Cloud and security operations teams often bear this responsibility.
A user’s traffic can be intercepted, redirected to another server, routed through another country and surveilled, and, as Muffett explained, for website operators, their DNS servers can be tampered with. “There are so many security risks up the stack,” Muffett said.
Mitigating against DDoS attacks in cloud-based environments can be a challenge, but current technologies make it possible for organizations to efficiently monitor their entire networks, analyze security logs at scale, and rapidly detect and respond to DDoS attacks before they impact user experience.
Passive DNS: The Context of IP Addresses When threat actors target financial institutions using ransomware, they deploy it via multiple IP addresses. (If Passive DNS — automatic, continuous monitoring of potential threats — is (and should be) a feature of complete DNS protection solutions. Download the use cases 1.

XDR (eXtended Detection and Response) Integrations At Black Hat USA 2023, Cisco Secure was the official Mobile Device Management, DNS (Domain Name Service) and Malware Analysis Provider. We also deployed ThousandEyes for Network Assurance. You can find the code and guide at this GitHub repository and the guide in this blog post.
Another example of guardrails is the use of networksecurity measures, such as DNS filtering, to restrict access to dangerous website categories. Monitor for gaps and take action when the right security steps aren’t taken. Observing security-related activities through log aggregation is a part of this.
Cybersecurity involves safeguarding networks, systems, and data from digital attacks, which are often aimed at accessing, stealing, or destroying sensitive information. There are several branches within cybersecurity, including networksecurity, application security, information security, and operational security.
dll NetworkSecurity Services (NSS) library from Mozilla. Enables various security protocols and cryptographic functions, which might be used for secure communication or data encryption. Could assist in leveraging Mozilla-based applications or libraries for data manipulation or other activities.
After this the adversary dumps the domain admin credentials from the memory of this machine, continues lateral moving through the network, and places Cobalt Strike beacons on servers for increased persistent access into the victim’s network. The DNS-responses weren’t logged. Command and control (TA0011).
LLMs can help attackers avoid signature based detection Traditionally, C2 traffic might be disguised as normal web traffic, DNS queries, or go through known platforms like Slack or Telegram. In the next blog I plan to dive further into the ways AI is being used to obscure attacks and evade legacy approaches. And of course weagree!
