Cloud computing has emerged as a popular computing paradigm in recent years. However, today's cloud computing architectures often lack support for computer forensic investigations. Analyzing various logs (e.g., process logs, network logs) plays a vital role in computer forensics. Unfortunately, collecting logs from a cloud is very hard given the black-box(More)
In our everyday lives, we create massive amounts of data. But how much does it really cost to store data? With ever decreasing cost of storage media, a popular misconception is that the cost of storage has become cheaper than ever. However, we argue that the cost of storing data is not equal to the cost of storage media alone – rather, many often ignored(More)

We propose a clustering algorithm, which is based on the assumption that if there is a common drop email address found in the phishing kits from two different phishing websites,(More)
