Spymax is a mobile Remote Administration Tool (RAT) that enables an attacker to control victims’ devices through an Android malware. Once the malware is installed on a phone, the attacker can execute many attacks that highly impact the confidentiality and integrity of the victim’s data, as well as the victim’s privacy. It is powerful, widely available, and does not require root privileges on the victim’s device. In this blogpost, I show the capabilities of this RAT and analyze how its Android malware works.
It’s Friday, you managed to escape for a couple of hours from a busy working day to see a doctor. Now you have to wait in a boring waiting room at the clinic until it’s your turn to see her majesty. What would you like to do in this time? Answer pending business emails, get lost in social media, or choose a new theme to make your iPhone look awesome? What about: all of the above? It’s nice to have everything on your iPhone: MDM enrollment to access business data, in addition to jailbreak for device freedom. However, MDM solutions ban jailbroken devices, because they are not secure enough to handle sensitive business data. And so, cat and mouse games of jailbreak detection/bypass between MDM solutions and some users develop.
In this blogpost, I highlight how this cat and mouse game with Google’s MDM solution “Google Endpoint Management” is currently going. First, I explain how to bypass jailbreak detection of Google’s MDM solution. Then I show how to manipulate MDM enforced policies on your MDM-enrolled jailbroken device. Since these actions have negative impacts on your device’s security, we’ll also discuss how attackers can exploit this insecure setup to steal business data.
“If it’s a thing, then there’s an app for it!”…We trust mobile apps to process our bank transactions, handle our private data and set us up on romantic dates. However, few of us care to wonder,”How (in)secure can these apps be?” Well… at Troopers 20, you can learn how to answer this question yourself!

In our 2 day long “Hacking mobile applications” workshop, we teach how to find security vulnerabilities in mobile apps, exploit them and defend against them. We start from scratch, therefore no prior experience in hacking or developing mobile apps is required. Whether you want to learn how to pentest mobile apps, you are an app developer that fancies to secure his/her apps, or just curios, our workshop is a jumpstart to your goal.
If you attack someone, they will defend themselves, but if you tickle them, they will eventually crack open. This surprisingly applies to Android apps as well! Therefore, I created AndroTickler, not to test apps against certain attacks or examine them for specific vulnerabilities, which developers would learn to avoid. However, it helps pentesters to analyze and test apps in their own style, but in a faster, easier and more flexible way. AndroTickler is a Swiss-Army-Knife pentesting tool for Android apps. It provides information gathering, static and dynamic analysis features, and also automates actions that pentesters frequently do and highly need during their pentests. In addition, it makes use of the powerful Frida to hook to the app and manipulate it in real-time.
IP Multimedia Subsystem (IMS) offers many multimedia services to any IP-based access network, such as LTE or DSL. In addition to VoLTE, IMS adds service provider flexibility, better QoS and charging control to the 4th generation of mobile networks. IMS exchanges SIP messages with its users or other IMS and usually these communications are secured by TLS or IPSec. But if an attacker manages to break the confidentiality and the integrity with IMS, he would find it vulnerable to several attacks.

Security Assertion Markup Language (SAML) is an XML standard for exchanging authentication and authorization data between a Service Provider (SP) and an Identification Provider (IdP). SAML is used in many Single Sign-On (SSO) implementations, when a user is authenticated once by IdP to access multiple related SPs. When a user requests to access a SP, it creates a SAML Authentication Request and redirects the user to IdP to be authenticated according to this authentication request. If the user is successfully authenticated, IdP creates a SAML authentication response and sends it back to SP through the user’s browser.
Denial of Service (DoS) attacks aim to make services and systems unavailable to legitimate users . If these attacks are performed by multiple sources at the same time and for the same target, they are called Distributed Denial of Service (DDoS) attacks. This talk “Imma Chargin Mah Lazer” describes different types of (D)DoS attacks that are out in the wild and are seen on a daily basis by different corporations. Furthermore, a multi-layered strategy to mitigate such kinds of attacks has been presented within the talk. The speaker is Dr. Oliver Matula, an IT security researcher at ERNW who holds a PHD degree in physics. He presented the topic in a simple way which eases the delivery of information to audience of different technical levels and backgrounds.
Wireshark in IP version 6 workshop was a part of IPv6 summit sessions of Troopers 16. It was held by Jeffery Carrell on the second day of IPv6 summit on Tuesday, the 15th of March. The workshop was generally divided into two sections: a short introduction to IPv6 and analyzing some IPv6 packets on Wireshark.
Some weeks ago Hendrik explained in his blogpost Security Analysis of VoLTE, Part 1 some attack vectors for Voice over LTE (VoLTE). One attack vector introduced was Denial of Service (DoS), which I also discussed in my Masterthesis “Evaluation of IMS security and Developing penetration tests of IMS”.
In general, DoS attacks aim to prevent a system or a network from efficiently providing its service to legitimate users . The impact of such attacks can vary from a big degradation of quality to total blockage. DoS can occur on users level, where a user or a group of users cannot use the service. But the common conception of DoS is on the service level, where the whole service is broken, unstable or totally down. This blog post is about targeting DoS of the whole VoLTE service by attacking IMS. Continue reading “Denial of Service attacks on VoLTE”
