Label:Flume is a highly available, highly reliable, distributed mass log collection, aggregation and transmission system. You can look at the model: Each flume agent can provide a flume service. Each agent has three members: source, channel, sink As shown, fetching data from source and sending it to Channel,channel is like a buffer, from which sink reads data from the channel. --------------------------

Analysis of SlemBunk Trojan Samples Reading: 584 SlemBunk was first discovered by FireEye. Later, some other security companies also found that the author had the honor to get the sample and analyzed the Trojan horse to find that its design was superb and can be further evolved on this basis. This sample is forged into some other commonly used android applications, deceiving users to input credit card-related sensitive information. Next we will analyz
