Wired is reporting on a new remote-access Trojan that is able to infect at least eighty different targets: So far, researchers from Lumen Technologies’ Black Lotus Labs say they’ve identified at least 80 targets infected by the stealthy malware, including routers made by Cisco, Netgear, Asus, and DrayTek.
The domain name system (DNS) is basically a directory of addresses for the internet. Your browser uses DNS to find the IP for a specific service. For example, when you enter esecurityplanet.com, the browser queries a DNS service to reach the matching servers, but it’s also used when you send an email. DNS spoofing or poisoning.

It enforces security at the DNS layer to block malware, phishing, and command and control callbacks over any port.
A PDNS service uses existing DNS protocols and architecture to analyze DNS queries and mitigate threats. Over a six-month period, the PDNS service examined more than 4 billion DNS queries to and from the participating networks, blocking millions of connections to identified malicious domains.
Domain name service (DNS) attacks threaten every internet connection because they can deny, intercept, and hijack connections. With the internet playing an increasing role in business, securing DNS plays a critical role in both operations and security. Everything You Need to Know.
The peculiarity of this new piece of malware is the ability to communicate with C2 servers via DNS over HTTPS ( DoH ). The DoH protocol was a new standard proposed in October 2018 and it is currently supported by several publicly available DNS servers. Only the second sample, the Windows one, appears to be continuously updated.
Network security architecture is a strategy that provides formal processes to design robust and secure networks. This article explores network security architecture components, goals, best practices, frameworks, implementation, and benefits as well as where you can learn more about network security architecture.

While external malware now faces greater permission restrictions, pre-installed malware within system partitions has become impossible to remove. The modular architecture of the malware gives attackers virtually unlimited control over the system, enabling them to tailor functionality to specific applications.
By increasing visibility into DNS traffic, CISOs can detect, block, and respond to incidents more quickly as well as use this data to institute new controls and increase overall resiliency. When malware first breaches a network, it doesn’t make its presence known right away. The issue likely comes down to awareness.

Experts noticed that the malware also downloads more shell scripts that retrieve brute-forcers that could be used to target devices protected with weak passwords.
Security experts from Sophos Labs have spotted a new piece of IoT malware tracked as Chalubo that is attempting to recruit devices into a botnet used to launch DDoS attacks. The attackers were using brute-force attacks (using the root:admin credential) on SSH servers to distribute the malware. ” continues the analysis.
The campaign was uncovered by CrowdStrike by investigating a series of security incidents in multiple countries, the security firm added that the threat actors show an in-depth knowledge of telecommunications network architectures. The report also includes additional malware and utilities used by the group along with a set of recommendations.
During the first week of May 2021, the Uptycs’ threat research team detected a shell script and Gafgyt malware downloading Simps binaries from the same C2- 23.95.80[.]200. On execution of the Simps binary, it drops a log file containing that the device has been infected with malware by Simps Botnet (see Figure 2). 200 (see figure 3).
Introduction It’s just another cryptocurrency miner… Nobody would even suspect the mining malware was merely a mask, masquerading behind an intricate modular framework that supports both Linux and Windows. This malware employed a custom EternalBlue SMBv1 exploit to infiltrate its victims’ systems.
And how can malware be future-proofed to evade the sophisticated EDR systems that currently exist and are actively being developed? Malware authors need to take execution speed, or other system changes, into account when deploying malware. In times of such an arms race, how does an attacker stay ahead?
Security experts have a new malware, dubbed skip-2.0 Security experts at ESET have discovered a new malware, dubbed skip-2.0, malware was used by threat actors to establish a backdoor in MSSQL Server 11 and 12 servers, allowing them to access to any account on the server using a “magic password.” The skip-2.0
A special thanks to our Professional Services’ IR team, ShadowServer , for historical context on C2 domains, and Thomas Roccia /Leandro Velasco for malware analysis support. McAfee customers are protected from the malware/tools described in this blog. The malware also decrypts and injects the payload in memory.
Cisco Umbrella : DNS visibility and security. Cisco Secure Malware Analytics (Formerly Threat Grid): for sandboxing and integrated threat intelligence. The original Black Hat NOC integration for Cisco was NetWitness sending suspicious files to Threat Grid (know Secure Malware Analytics).
Jeremy Brown helped Trinity Cyber develop counter maneuvers for a DNS exploit requiring deep parsing of a certain kind of traffic, deploying it to all clients in less than two days. They developed a powerful new approach to intrusion prevention system as-a-service, delivered through a service edge architecture and patent-pending technology.
Out of the 18,000 Orion IT customers affected by the malware, it seems that only a handful were of interest to the attackers. For example, before making the first internet connection to its C2s, the Sunburst malware lies dormant for up to two weeks, preventing easy detection of this behaviour in sandboxes.
To explore these scams, we used a dedicated computer, segmented from the rest of the network, and leveraged Cisco Secure Malware Analytics to safely open the emails before clicking on links or opening attachments. According to Cisco Umbrella , many of the sites asking for credit card details are known phishing sites, or worse, host malware.
