The lament of security analysts is often a limitation in the amount of data they can process, and the ensuing loss of data fidelity as size increases. Once properly classified, devices can be interacted with in simple and efficient ways that will be revealed by the speaker.įinding Needles in Haystacks (The Size of Countries)
Therefore, understanding the threat models associated with these devices and the telephone network will allow mobile researchers and embedded engineers to correctly implement security solutions that minimize a device’s exposure to threat actors.Įmpirical evidence will be presented that demonstrates creative and successful ways to classify potential devices amongst millions of phone numbers world wide. Additionally, devices attached to the phone network cannot be easily compartmentalized or firewalled from potential abusers the same way that IP enabled systems can. These systems are increasingly capable of affecting the physical world around us. As a result, it is imperative for mobile researchers to understand how these systems can be detected by attackers on the global telephone network, then potentially abused.
These messages can trigger actions such as firmware updates, Are You There requests, or even solicitations for data. These systems often receive control messages over the telephone network in the form of text messages (SMS) or GPRS data. Today, A- GPS tracking devices, 3G Security Cameras, Urban Traffic Control systems, SCADA sensors, Home Control and Automation systems, and even vehicles are now telephony enabled. Now, there is a growing shift in the nature of the devices that are accessible over the telephone network. Typically, we think of these devices in terms of modems, faxes, or TTY systems. War Texting: Weaponizing Machine to Machine Systemsĭevices have been attached to the telephone network for years. Finally, these tests will also show which OS appears to be the most immune to IPv6 fragmentation attacks. As it will be explained, such attacks, under specific circumstances can lead to OS fingerprinting, IDS insertion/evasion and firewalls evasions.

In each case, the corresponding proof of concept code is provided. As it will be shown, most of the popular OS, such as Windows, Linux and OpenBSD are susceptible to such attacks. To this end, several fragmentation attacks will be presented and their impact will be examined. In this paper, it will be examined whether fragmentation issues still remain in IPv6 implementation of some of the most popular Operating Systems and whether they can also be used for the aforementioned purposes. The adoption of the new IP version, IPv6, has opened new potential exploitation fields to the attackers and pen testers. There are many publications regarding their exploitation for various purposes, including, but not limited to, OS fingerprinting, IDS/IPS insertion/evasion, firewall evasion and even remote code execution. IP fragmentation attacks is not a new issue.
Indeed, what would happen to us if chicken pox, measles, or rotavirus played cat and mice with medical doctors and continuously learned to detect test tubes (virtual machines) and microscopes (reverse engineering tools)?įinally, considering the advances of cybernetics, we contemplate the possibilities of actually witnessing a convergence between human and computer viruses in a more or less distant future.Īntonios Atlasis Attacking IPv6 Implementation Using Fragmentation On the other hand, there are few techniques we can only be grateful biology has not picked up yet, and dearly hope viruses won’t ever evolve from BlackHat attendees genomes. For instance, Influenza, who intentionally omits a replication error checking protein to have copies randomly mutate, is a potential nominee. We intend to give them credit for some of their best attack scenarios. Have you ever wondered how much those nasty biological viruses actually invented before Black Hats did? They surely invented brute-force attacks, polymorphism and time bombs, and yet, they never presented at BlackHat for this! In this presentation, we wish to push the comparison further down into the details of implementation and attack strategies. An Attacker’s Day into Virology: Human vs ComputerĬomputer virology bares such a strong resemblance with Human virology that both worlds have often been compared humorously.
