Description = 'How to Crack Mifare Classic Cards' title = 'How to Crack Mifare Classic Cards' date = '2015-04-21T19:20:00+01:00' In this blog post I will cover some quick basics about NFC, Mifare Classic and how to set up everything for reading and writing a NFC tag. At the end I show you how to reprogram a vending machine's NFC tag to contain more credits.

NFC stands for Near Field Communication and is used to communicate over short distances. For more Infos on NFC you can read the.

NFC nowadays is used for access cards, public transport, some more and in this case: Vending Machines. Basically there is an active NFC enabled device (the reader) and a passive device (the tag). The active device scans for the passive one and establishes a connection on contact. It also powers the passive device via an electromagnetic field. There is also an active - active mode where both endpoints can send data and need to be powered seperately. This is usually used when sending data for example in 'Android Beam'. In this example the vending machine has an active NFC reader built in.

You can touch it with your tag to buy some drinks and the corresponding price is subtracted from the ammount stored on the tag. You can also recharge your tag via the machine if you run out of credits. The NFC tag I analyzed is a so called 'Mifare Classic 1k' tag. 1k stands for the size of data the tag can store. There are also other types like the 'Mifare Classic 4k' and the 'Mifare Mini' each having a different memory size. Mifare Classic in general is stated insecure, because it's encryption protocol has been cracked.

More deatiled Information about this can be found in the following links: A Mifare Classic 1k tag contains 16 sectors. Each of these sectors has 3 blocks of data storage and 1 block for storing the secret access keys and access controls. Each block contains 16 bytes of data. Before reading a sector, the reader must authenticate to the tag with a secret access key. Each sector has two keys: Key A and Key B Each of the 16 sectors can define it's own access right and wich key is needed for a particular action.

As an example you can define to use Key A for reading the block and Key B for writing to it. Sector 0 Block 0 also contains a non changeable UID (the tags unique ID) and some manufacturer data. This section is only writeable on some special chinese tags. Here is a basically memory layout of a Mifare Classic tag: (taken from the Mifare Datasheet, link see below) More about Mifare in general can be found on. For more information on Mifare 1k Tags, the memory layout and more details you can visit these pages: Now I will demonstrate how to get all access keys for all sectors, locate the credits and modify them. For this example I used the connected via an and as an alternative a Raspberry Pi with the PN352 Breakout Board.

These items can be purchased from various online shops around the world. For connection instructions on the Raspberry Pi please refer to. Important notice: NFC and the used attack depend a lot on timing. Connecting a NFC device to a VM running linux will not work reliable because the drivers mess with this timing. I spent a lot of time finding this out, so please boot into a linux live cd for the following example or use a Raspberry Pi. Here are the basics to set your machine up for getting the access keys.

The first step is to set up libnfc so the OS can communicate with the NFC reader. You can get the latest libnfc version from. At the time of writing the current version was 1.7.1.

Ulrich Pilster 2014-08-01 Full Text Available While there were several relatively short uprisings in Northern Africa and the Middle East during the Arab Spring, the dispute between the rebels and government forces in Syria has evolved into a full-scale civil war. We try to predict the length of the Syrian insurgency with a three-stage technique.

Using out-of-sample techniques, we first assess the predictive capacity of 69 explanatory variables for insurgency duration. After determining the model with the highest predictive power, we categorize Syria according to the variables in this final model. Based on in-sample approaches, we then predict the duration of the Syrian uprising for three different scenarios. The most realistic point prediction is 5.12 years from the insurgency’s start, which suggests an end date between the end of 2016 and early 2017. 2014-06-13 decision making of criminology scholarship to predict why attacks occur within space and time.

Helwan, Abdulkader 2015-01-01 Heart attack is an asymptomatic and epidemic medical condition that may suddenly occur and causes “death”. Therefore, it is a life-threatening condition and it should be detected before it occurs. Heart attack is so far predicted using the conventional ways of doctor’s examination and by performing some medical tests such as stress test, ECG, and heart CTScan etc.

The coronary vessels constriction, the cholesterol levels in the arteries, and other attributes can be good indicators for making. Peng Liu 2005-11-28 The area investigated by this project is cyber attack prediction. With a focus on correlation-based prediction, current attack prediction methodologies overlook the strategic nature of cyber attack-defense scenarios. As a result, current cyber attack prediction methodologies are very limited in predicting strategic behaviors of attackers in enforcing nontrivial cyber attacks such as DDoS attacks, and may result in low accuracy in correlation-based predictions.

This project develops a game theoretic framework for cyber attack prediction, where an automatic game-theory-based attack prediction method is proposed. Being able to quantitatively predict the likelihood of (sequences of) attack actions, our attack prediction methodology can predict fine-grained strategic behaviors of attackers and may greatly improve the accuracy of correlation-based prediction. To our best knowledge, this project develops the first comprehensive framework for incentive-based modeling and inference of attack intent, objectives, and strategies; and this project develops the first method that can predict fine-grained strategic behaviors of attackers. The significance of this research and the benefit to the public can be demonstrated to certain extent by (a) the severe threat of cyber attacks to the critical infrastructures of the nation, including many infrastructures overseen by the Department of Energy, (b) the importance of cyber security to critical infrastructure protection, and (c) the importance of cyber attack prediction to achieving cyber security.

Cui, Xiaohui ORNL; Potok, Thomas E ORNL 2009-12-01 To better understand insurgent activities and asymmetric warfare, a social adaptive model for modeling multiple insurgent groups attacking multiple military and civilian targets is proposed and investigated. This report presents a pilot study using the particle swarm modeling, a widely used non-linear optimal tool to model the emergence of insurgency campaign. The objective of this research is to apply the particle swarm metaphor as a model of insurgent social adaptation for the dynamically changing environment and to provide insight and understanding of insurgency warfare. Our results show that unified leadership, strategic planning, and effective communication between insurgent groups are not the necessary requirements for insurgents to efficiently attain their objective.

Bohorquez, Juan Camilo; Gourley, Sean; Dixon, Alexander R; Spagat, Michael; Johnson, Neil F 2009-12-17 Many collective human activities, including violence, have been shown to exhibit universal patterns. The size distributions of casualties both in whole wars from 1816 to 1980 and terrorist attacks have separately been shown to follow approximate power-law distributions.

However, the possibility of universal patterns ranging across wars in the size distribution or timing of within-conflict events has barely been explored. Here we show that the sizes and timing of violent events within different insurgent conflicts exhibit remarkable similarities. We propose a unified model of human insurgency that reproduces these commonalities, and explains conflict-specific variations quantitatively in terms of underlying rules of engagement. Our model treats each insurgent population as an ecology of dynamically evolving, self-organized groups following common decision-making processes. Our model is consistent with several recent hypotheses about modern insurgency, is robust to many generalizations, and establishes a quantitative connection between human insurgency, global terrorism and ecology.

Its similarity to financial market models provides a surprising link between violent and non-violent forms of human behaviour. 2013-05-23 command nodes, and rail networks, denying the enemy the ability to operationally maneuver his forces.4 This rapid maneuver, coupled with attacks.insurgencies, each with unique aims and methods to achieve those aims.

The system comprises two parts.

First part analyzes and identifies the factors which affect the prediction. Admitting incomplete information and use of linguistic terms by experts, as two characteristic features of this peculiar prediction problem we exploit the Theory of Fuzzy Soft Sets. Hence the Part 2 of the model is an algorithm vz. FSP which takes the assessment of factors given in Part 1 as its input and produces a possibility profile of cities likely to receive the accident.

The algorithm is of O(2^n) complexity. It has been illustrated by an example solved in detail. Simulation results for the algorithm have been presented which give insight into the strengths and weaknesses of FSP.

Khalili, Aram; Michalk, Brian; Alford, Lee; Henney, Chris; Gilbert, Logan 2010-04-01 In most organizations, IT (information technology) infrastructure exists to support the organization's mission. The threat of cyber attacks poses risks to this mission. Current network security research focuses on the threat of cyber attacks to the organization's IT infrastructure; however, the risks to the overall mission are rarely analyzed or formalized. This connection of IT infrastructure to the organization's mission is often neglected or carried out ad-hoc.

Our work bridges this gap and introduces analyses and formalisms to help organizations understand the mission risks they face from cyber attacks. Modeling an organization's mission vulnerability to cyber attacks requires a description of the IT infrastructure (network model), the organization mission (business model), and how the mission relies on IT resources (correlation model). With this information, proper analysis can show which cyber resources are of tactical importance in a cyber attack, i.e., controlling them enables a large range of cyber attacks.

Such analysis also reveals which IT resources contribute most to the organization's mission, i.e., lack of control over them gravely affects the mission. These results can then be used to formulate IT security strategies and explore their trade-offs, which leads to better incident response. This paper presents our methodology for encoding IT infrastructure, organization mission and correlations, our analysis framework, as well as initial experimental results and conclusions.

Diab 2014-09-01 Full Text Available This work was divided into two phases. Phase one included the validation of neural network to predict mortar and concrete properties due to sulfate attack. These properties were expansion, weight loss, and compressive strength loss. Assessment of concrete compressive strength up to 200 years due to sulfate attack was considered in phase two. The neural network model showed high validity on predicting compressive strength, expansion and weight loss due to sulfate attack. Design charts were constructed to predict concrete compressive strength loss. The inputs of these charts were cement content, water cement ratio, C3A content, and sulfate concentration.

These charts can be used easily to predict the compressive strength loss after any certain age and sulfate concentration for different concrete compositions. Sanjeeb Nanda 2008-04-01 Full Text Available The rapid growth of the Internet has triggered an explosion in the number of applications that leverage its capabilities. Unfortunately, many are designed to burden or destroy the capabilities of their peers and the network's infrastructure. Hence, considerable effort has been focused on detecting and predicting the security breaches they propagate. However, the enormity of the Internet poses a formidable challenge to analyzing such attacks using scalable models. Furthermore, the lack of complete information on network vulnerabilities makes forecasting the systems that may be exploited by such applications in the future very hard. This paper presents a technique for deriving a scalable model for representing network attacks, and its application to identify actual attacks with greater certainty amongst false positives and false negatives.

It also presents a method to forecast the propagation of security failures proliferated by an attack over time and its likely targets in the future.

Single comparisons between groups of agoraphobic and non-agoraphobic patients were carried out and a logistic regression model was applied. Occurrence of the first panic attack in public and the feeling of embarrassment were found to be significantly associated with the development of agoraphobia. It is concluded that eliciting this specific form of social concern at an early stage might help to identify patients at risk for later agoraphobia, which could, in turn, help to further specify early therapeutic interventions and concentrate therapeutic efforts on a high-risk group of panic disorder patients. 2010-01-01 indiscriminate, terrorism as the first step in “ bourgeois -nationalist” insurgencies where a fledgling movement is seeking to gain notoriety for its cause.8.2005), 146. 32 Mary Louise Kelly, “Is Al Qaida Stronger Six Years after Sept.

However, much less is known about risk factors for the development of panic attacks, particularly during adolescence when the incidence of panic attacks increases dramatically. We examined whether internalizing and externalizing problems in childhood predict the onset of panic attacks in adolescence. METHOD: This study is part of the TRacking Adolescents' Individual Lives Survey (TRAILS, a Dutch longitudinal population cohort study (N = 1,584. Internalizing and Externalizing Problems were collected using the Youth Self-Report (YSR and the parent-report Child Behavior Checklist (CBCL at baseline (age 10-12. At age 18-20, DSM-IV defined panic attacks since baseline were assessed with the Composite International Diagnostic Interview (CIDI. We investigated whether early adolescent Internalizing and Externalizing Problems predicted panic attacks between ages 10-20 years, using survival analysis in univariate and multivariate models.

RESULTS: There were N = 314 (19.8% cases who experienced at least one DSM-IV defined panic attack during adolescence and N = 18 (1.2% who developed panic disorder during adolescence. In univariate analyses, CBCL Total Problems, Internalizing Problems and three of the eight syndrome scales predicted panic attack onset, while on the YSR all broad-band problem scales and each narrow-band syndrome scale predicted panic attack onset.

The Mach number of the oncoming flow is 6, the cone half-angle is 5Ω, and the angle of attack is 1Ω. The conventional eN method is used, but the transition location so obtained is obviously incorrect.

The reason is that in the conventional method, only the amplifying waves are taken into ac-count, while in fact, for different meridians the decay processes of the disturbances before they begin to grow are different. Based on our own previous work, new interpretation and essential improvement for the eN method are proposed. Not only the amplification process but also the decay process is con-sidered.

The location, where by linear stability theory, the amplitude of disturbance wave is amplified from its initial small value to 1%, is considered to be the transition location. The new result for transi-tion prediction thus obtained is found to be fairly satisfactory. It is also indicated that for the calculation of base flow, boundary layer equations can be used for a small angle of attack.

Its computational cost is much smaller than those for DNS. Pavlov-Dolijanovic, Slavica; Damjanov, Nemanja S; Vujasinovic Stupar, Nada Z; Radunovic, Goran L; Stojanovic, Roksanda M; Babic, Dragan 2013-04-01 To assess the prognostic value of the age at onset of Raynaud's (RP) and of a history of exacerbation of RP attacks for the development of connective tissue disease (CTD) in patients initially found to have primary Raynaud's. 3,035 patients with primary RP (2,702 women and 333 men) were followed for an average of 4.8 years (range from 1 to 10 years). At baseline and every 6 months, they were screened for signs and symptoms of CTD. At 4.8 years of follow-up, 54.7% patients remained as primary RP, 8.1% had developed suspected secondary RP, and 37.2% had developed a definite CTD. Primary RP patients had an earlier onset of RP (mean age of 32.2 years) than those with suspected (mean age 36.5 years, P =.007) or definite secondary RP associated with CTD (mean age of 39.8 years, P =.004).

RP beginning before the age of forty was not significantly associated with the development of CTD. Conversely, the appearance of RP after the age of 40 was significantly associated with the development of CTD (P =.00001). Worsening of RP attacks predicted the development of CTD, especially systemic sclerosis (relative risk RR of 1.42), scleroderma overlap syndrome (RR of 1.18), and mixed CTD (RR of 1.18). Patients whose onset of RP occurred past 40 years of age and those with worsening RP attacks were at risk for the future development of CTD.

Patients with first-time anterior circulation TIA (diagnosed within 24 h of onset) and normal cognition, treated between August 2009 and August 2014 at the Department of Neurology of Chengdu Military General Hospital, China, were analyzed retrospectively. Patients underwent whole-brain CTPI within 1 week of TIA to detect cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT) and time to peak (TTP) in the ischemic region. Based on cognitive function assessment 4 weeks after TIA, using the Montreal cognitive assessment (MoCA) and mini mental state examination, the patients were divided into control and VCI groups. CTPI parameters and other clinical data were compared between groups, and Spearman's correlation analysis used to identify associations between cognitive scores and CTPI parameters in the VCI group. 50 patients (25 per group; aged 55-72 years) were included.

Patient age, gender, smoking status, alcohol consumption, educational level, time from TIA onset to admission, time from TIA onset to CTPI, and prevalence of hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation and hyperhomocysteinemia did not differ between groups. Both groups showed TTP and MTT prolongation, CBF reduction, but no change in CBV in the ischemic region; these changes were significantly larger in the VCI group (P.
