Mobile Security
SS7 Attacker Heaven turns into Riot: How to make Nation-State and Intelligence Attackers’ lives much harder on mobile networks 2019.
SS7/Diameter firewall:
https://github.com/P1sec/SigFW
Problem Statement
The international SS7 network has been standardized and built in the past as a trusted network with only trusted partners. The network itself and by design does not authenticate and authorize the peers in the network and also does not encrypt the signaling communication. The exposure of these networks comes from the design and the architecture requirement of roaming architecture in past architecture releases.
Additionally we should not expect that the SS7 network will be phased out soon. The voice could be replaced by VoLTE (4G) with IMS home routed architecture, but such deployment requires VoLTE capable devices and VoLTE networks with the similar radio coverage compared to 2G, 3G. So before some operator decides to shut-down both 2G and 3G network, all the home subscribers should be VoLTE enabled. And the operator should also consider inbound-roamers.
In the LTE the Diameter protocol has replaced the SS7 signaling. However, similar issues are still present. Lack of authentication and no encryption of the signaling communication.

Muddling Meerkat: The Great Firewall Manipulator 2024
This paper introduces a perplexing actor, Muddling Meerkat, who appears to be a People’s Republic of China (PRC) nation state actor. Muddling Meerkat conducts active operations through DNS by creating large volumes of widely distributed queries that are subsequently
propagated through the internet using open DNS resolvers. Their operations intertwine with two topics tightly connected with China and Chinese actors: the Chinese Great Firewall (GFW) and Slow Drip, or random prefix, distributed denial-of-service (DDoS) attacks. While Muddling Meerkat’s operations look at first glance like DNS DDoS attacks, it seems unlikely that denial of service is their goal, at least in the near term.
Muddling Meerkat operations are long-running — apparently starting in October 2019 – and demonstrate a high degree of expertise in DNS.
Muddling Meerkat’s operations are complex. Indeed, they are so convoluted, one might assume that Muddling Meerkat presents no threat. But in cybersecurity, especially in the complex world of DNS, we should think strategically. In February 2024, the U.S. Cybersecurity
and Infrastructure Security Agency (CISA) and several international partners issued an advisory saying, “In recent years, the U.S. has seen a strategic shift in PRC cyber threat activity from a focus on espionage to pre-positioning for possible disruptive cyber attacks
against U.S. critical infrastructure.”
While that specific advisory focused on “living off the
land” techniques used by the actor Volt Typhoon, the message that “PRC cyber actors blend in with normal system and network activities, avoid identification by network defenses, and limit the amount of activity that is captured in common logging configurations” is eerily
similar to how well-hidden Muddling Meerkat remains.

ABSTRACT:
Internet of Things (IoT) devices are gaining more and more importance in our daily lives. Through their deep integration they pose a potential risk for the user’s privacy. In this thesis, I use reverse engineering methods to analyze the security of the Xioami IoT ecosystem and its devices. I implement a tool to emulate the Xiaomi cloud and analyze the cloud protocol. I use different, some unconventional, methods to extract the device firmware and get privileged access on the devices. The evaluation shows that, even though Xiaomi is a large IoT company, their cloud protocol and Software Development Kit (SDK) have serious flaws. Also, the actual vendors of the devices do not put much effort into device security. A slightly positive aspect of this is the fact that users can use the flaws to get full control over their own devices.

Unit42 Incident Response Report 2024:
How This Report Helps You
New headlines covering nation-state threat actors come out every day–not to mention news of the latest vulnerabilities and security risks. Your time is more valuable than ever, and sorting out which threats really matter is a difficult task.
This report helps because it gathers real-world information from organizations like yours, so you can learn which threats really affect your peers–and how you can face them. Read on to find out how threat actors gain access to organizations, what they do once they get in, and how our incident responders’ top recommendations help you stop them.
Cybersecurity can often feel like an endless battle between attackers and defenders. At Unit 42, we believe intelligence, insight, and preparation still gives defenders the edge. We think the story of cybersecurity can be hopeful, with a strategic understanding of the threats we face today.

For CISSP students, I have summarized here CISSP changes in 2024:
Rearranging the sequence and renaming topics within the curriculum is unlikely to substantially affect the exam outcome. This is because the exam emphasizes the application of theoretical concepts in real-world Cyber/Information Security scenarios rather than relying solely on definitions and theoretical knowledge. Consequently, the exam incorporates numerous practical scenarios and questions derived from hands-on experience, which are challenging to master through theoretical study alone
