WhatsApp network forensics: Decrypting and understanding the WhatsApp call signaling messages

WhatsApp is a widely adopted mobile messaging application with over 800 million users. Recently, a calling feature was added to the application and no comprehensive digital forensic analysis has been performed with regards to this feature at the time of writing this paper. In this work, we describe how we were able to decrypt the network traffic and obtain forensic artifacts that relate to this new calling feature which included the: a) WhatsApp phone numbers, b) WhatsApp server IPs, c) WhatsApp audio codec (Opus), d) WhatsApp call duration, and e) WhatsApp's call termination. We explain the methods and tools used to decrypt the traffic as well as thoroughly elaborate on our findings with respect to the WhatsApp signaling messages. Furthermore, we also provide the community with a tool that helps in the visualization of the WhatsApp protocol messages.     

Improving court-appearance rates through court-date reminder phone calls

Without a defendant’s appearance in court, the adjudication of criminal charges cannot proceed. The low defendant court appearance rates of Lafayette Parish, Louisiana were identified as a high priority to address. A pilot project was implemented, in which, Lafayette Parish Sheriff’s Office (LPSO) Information Officers would call defendants approximately 5–9 days before their pretrial court appearance. This process began in September 2014. LPSO staff attempted to call all non-incarcerated or diverted defendants with known contact information. LPSO staff documented when calls were made and the type of response (spoke to defendant, left a voicemail, no answer, inoperable phone or spoke to friend or family member). Calls were made to defendants with court appearances in arraignment hearings, misdemeanor pretrial and trial, felony pretrial and traffic court. Court appearance rates for all court hearings increased from 48 to 62%.     

Calling the cops: Police telephone operators and citizen calls for service

Citizen calls for police service represent direct demands on government. It is the job of police phone operators to translate these demands into official, bureaucratically recognized inputs. As “street-level” bureaucrats, police phone operators enjoy considerable discretion in how they recieve, process, and transmit information. Operators screen all calls, categorize the citizen's problem, and by that process they determine much of the initial police response to that call. This article analyzes data on citizen requests and operator responses coded from a sample of over 26,000 phone calls to police in 21 jurisdictions in three metropolitan areas. The data indicate that most citizen calls to police involve the provision of information or assistance, nuisance abatement, traffic problems, or the regulation of interpersonal disputes. Citizen calls cover a wide range of topics, but only about 20 percent involve predatory crime of any type. The typical operator response to the problems described by most citizens was to promise the dispatch of a patrol unit, although this varied by problem type and by the apparent seriousness of the call. Complaint operators seem to follow a decision rule that a patrol unit will always be sent to the scene except in those situations where it is clear that none is needed. The article concludes with a discussion of the possible impact of operator demeanor on policy-community relations.

交通肇事后的报警行为不成立自首之法理抉微

《刑法》第133条规定的逻辑结构决定了如若将交通肇事者肇事后报警并保护事故现场的行为认定为自首,将违反刑法禁止重复评价原则。通过与交通肇事罪同质的其他过失犯罪的法定刑配置对比,可得出交通肇事罪的基本法定刑适用情形中包含了肇事者报警并保护事故现场的内容之结论。其他法律、法规为肇事者设定自首义务有其心理学基础且契合作为法的整体精神。肇事者逃逸后又自动投案并如实供述自己罪行的成立本罪之自首。     

A survey of current social network and online communication provision policies to support law enforcement identify offenders

Online forms of harassment, stalking and bullying on social network and communication platforms are now arguably wide-spread and subject to regular media coverage. As these provision continue to attract millions of users, generating significant volumes of traffic, regulating abuse and effectively reprimanding those who are involved in it, is a difficult and sometimes impossible task. This article collates information acquired from 22 popular social network and communication platforms in order to identify current regulatory gaps. Terms of service and privacy policies are reviewed to assess existing practices of data retention to evaluate the feasibility of law enforcement officials tracking those whose actions breach the law. For each provision, account sign-up processes are evaluated and policies for retaining Internet Protocol logs and user account information are assessed along with the availability of account preservation orders. Finally, recommendations are offered for improving current approaches to regulating social network crime and online offender tracking.     

Severity of vehicle bumper location in vehicle-to-pedestrian impact accidents

Pedestrian protection is one of the key topics for safety measures in traffic accidents all over the world. To analyze the relation between the collision site of the vehicle bumper and the severity of the lower extremity injuries, we performed biomechanical experiments. We compared the applied external force and the risks of subsequent injuries between the impact of the center and side positions of the front bumper. These comparisons were performed by practical impact tests with eight typical different types of cars which were typical of the current vehicle fleets. The tests were made using the TRL legform impactor which was a mechanical substitute of a pedestrian lower extremity. The TRL impactor is used all over the world for assessing the safety of car bumpers. It was found that the risks of lower extremity injuries in the impacts at the side positions, in front of the vehicle's side member, were significantly higher than those at the center. In the tests, we found that foam materials around the rigid front cross member had a significant effect on reducing the lower extremity injury risks and especially tibia fracture risk against vehicle bumper center collisions, but had little effect at the sides of the bumper over the vehicle's side members where the foam was thinner. We also found that the front shape of the vehicle affected the risk of ligaments injuries. According to these results, the information of impact locations of cars in vehicle-to-pedestrian traffic accidents is valuable for clinicians to diagnose patients with lower extremity injuries in traffic accidents and for forensic pathologists to analyze the accident reconstruction. Furthermore, the results suggest that testing of the bumper area in front of the main longitudinal beams should be included in the car safety legislation to require pedestrian safety.     

Balancing data protection and privacy – The case of information security sensor systems

This article analyses government deployment of information security sensor systems from primarily a European human rights perspective. Sensor systems are designed to detect attacks against information networks by analysing network traffic and comparing this traffic to known attack-vectors, suspicious traffic profiles or content, while also recording attacks and providing information for the prevention of future attacks. The article examines how these sensor systems may be one way of ensuring the necessary protection of personal data stored in government IT-systems, helping governments fulfil positive obligations with regards to data protection under the European Convention on Human Rights (ECHR), the EU Charter of Fundamental Rights (The Charter), as well as data protection and IT-security requirements established in EU-secondary law. It concludes that the implementation of sensor systems illustrates the need to balance data protection against the negative privacy obligations of the state under the ECHR and the Charter and the accompanying need to ensure that surveillance of communications and associated metadata reach established principles of legality and proportionality. The article highlights the difficulty in balancing these positive and negative obligations, makes recommendations on the scope of such sensor systems and the legal safeguards surrounding them to ensure compliance with European human rights law and concludes that there is a risk of privatised policymaking in this field barring further guidance in EU-secondary law or case law.

The Worldwide Search for Techno-thieves: International Competition v. International Co-operation

In an age of explosive worldwide growth of electronic data storage and communications, many vital interests require the effective protection of information. Today's information age requires businesses to compete on a worldwide basis, sharing sensitive information with appropriate parties while protecting that information against competitors, vandals, suppliers, customers, and foreign governments. Elements of the US civilian infrastructure, such as the banking system, the electric power grid, the public switched telecommunications network, and the air traffic control system, are central to so many dimensions of modern life that protecting these elements must have a high priority. Governments have an important stake in assuring that rival nations do not appropriate technology.
