MobileAppScrutinator: A Simple yet Efficient Dynamic Analysis Approach for Detecting Privacy Leaks across Mobile OSs
Smartphones, the devices we carry everywhere with us, are being heavily
tracked and have undoubtedly become a major threat to our privacy. As "tracking
the trackers" has become a necessity, various static and dynamic analysis tools
have been developed in the past. However, today, we still lack suitable tools
to detect, measure and compare the ongoing tracking across mobile OSs. To this
end, we propose MobileAppScrutinator, based on a simple yet efficient dynamic
analysis approach, that works on both Android and iOS (the two most popular OSs
today). To demonstrate the current trend in tracking, we select 140 most
representative Apps available on both Android and iOS AppStores and test them
with MobileAppScrutinator. In fact, choosing the same set of apps on both
Android and iOS also enables us to compare the ongoing tracking on these two
OSs. Finally, we also discuss the effectiveness of privacy safeguards available
on Android and iOS. We show that neither Android nor iOS privacy safeguards in
their present state are completely satisfying
SmartUnit: Empirical Evaluations for Automated Unit Testing of Embedded Software in Industry
In this paper, we aim at the automated unit coverage-based testing for
embedded software. To achieve the goal, by analyzing the industrial
requirements and our previous work on automated unit testing tool CAUT, we
rebuild a new tool, SmartUnit, to solve the engineering requirements that take
place in our partner companies. SmartUnit is a dynamic symbolic execution
implementation, which supports statement, branch, boundary value and MC/DC
coverage. SmartUnit has been used to test more than one million lines of code
in real projects. For confidentiality motives, we select three in-house real
projects for the empirical evaluations. We also carry out our evaluations on
two open source database projects, SQLite and PostgreSQL, to test the
scalability of our tool since the scale of the embedded software project is
mostly not large, 5K-50K lines of code on average. From our experimental
results, in general, more than 90% of functions in commercial embedded software
achieve 100% statement, branch, MC/DC coverage, more than 80% of functions in
SQLite achieve 100% MC/DC coverage, and more than 60% of functions in
PostgreSQL achieve 100% MC/DC coverage. Moreover, SmartUnit is able to find the
runtime exceptions at the unit testing level. We also have reported exceptions
like array index out of bounds and divided-by-zero in SQLite. Furthermore, we
analyze the reasons of low coverage in automated unit testing in our setting
and give a survey on the situation of manual unit testing with respect to
automated unit testing in industry.Comment: In Proceedings of 40th International Conference on Software

Forum Session at the First International Conference on Service Oriented Computing (ICSOC03)
The First International Conference on Service Oriented Computing (ICSOC) was held in Trento, December 15-18, 2003. The focus of the conference ---Service Oriented Computing (SOC)--- is the new emerging paradigm for distributed computing and e-business processing that has evolved from object-oriented and component computing to enable building agile networks of collaborating business applications distributed within and across organizational boundaries. Of the 181 papers submitted to the ICSOC conference, 10 were selected for the forum session which took place on December the 16th, 2003. The papers were chosen based on their technical quality, originality, relevance to SOC and for their nature of being best suited for a poster presentation or a demonstration. This technical report contains the 10 papers presented during the forum session at the ICSOC conference. In particular, the last two papers in the report ere submitted as industrial papers
Statically Checking Web API Requests in JavaScript
Many JavaScript applications perform HTTP requests to web APIs, relying on
the request URL, HTTP method, and request data to be constructed correctly by
string operations. Traditional compile-time error checking, such as calling a
non-existent method in Java, are not available for checking whether such
requests comply with the requirements of a web API. In this paper, we propose
an approach to statically check web API requests in JavaScript. Our approach
first extracts a request's URL string, HTTP method, and the corresponding
request data using an inter-procedural string analysis, and then checks whether
the request conforms to given web API specifications. We evaluated our approach
by checking whether web API requests in JavaScript files mined from GitHub are
consistent or inconsistent with publicly available API specifications. From the
6575 requests in scope, our approach determined whether the request's URL and
HTTP method was consistent or inconsistent with web API specifications with a
precision of 96.0%. Our approach also correctly determined whether extracted
request data was consistent or inconsistent with the data requirements with a
precision of 87.9% for payload data and 99.9% for query data. In a systematic
analysis of the inconsistent cases, we found that many of them were due to
errors in the client code. The here proposed checker can be integrated with
code editors or with continuous integration tools to warn programmers about
code containing potentially erroneous requests.Comment: International Conference on Software Engineering, 201
