, and rootkit. I 'd like to focus on the dropper, since it's where much of the confusion lies. In that article, I did not spend much time on the dissemination process. Now I want to correct it. Malware that spread rootkit is called a hybrid threat because it contains three parts: the downloader, the loader, And the rootkit. I want to focus on the downloader, because it has a lot of chaotic lies. Dropper Pro

single as possible, so I will not change the gcrawler. Another method is to implement it in the spider class. I originally planned to write a batch download spider, but later I found that the implementation can be modified based on the original downloader class, so I directly changed the downloader class. This is the current example. BaseThe idea is that the scheduler generator will wait for the next parsi

Scrapy mainly has the following components:1, Engine (scrapy)Used to process the entire system's data flow, triggering transactions (framework core)2, Scheduler (Scheduler)Used to receive a request from the engine, pressed into the queue, and returned when the engine requests again, can be imagined as a URL (crawl web site URL or link) Priority queue, it determines the next crawl URL is what, while removing duplicate URLs3, Downloader (

including the spider) mainly does event scheduling, regardless of the URL's storage. Looks like the Gooseeker member center of the crawler Compass, for the target site to prepare a batch of URLs, placed in the compass ready to perform crawler operation. So, the next goal of this open source project is to put the URL management in a centralized dispatch repository.The Engine asks the Scheduler for the next URLs to crawl.It's hard to understand what it's like to see a few other documents to under

information is based on the calculation of the target file generated. The main principle of the file information is to provide the downloaded file virtual into the equal size of the block , the block size must be 2k of the whole number of square (because it is a virtual block, the hard disk does not produce individual block files), and the index information of each block and hash verification code into the seed file; The seed file is the "index" of the downloaded file. To download the cont

Introduction Previously, I used scrapy to write some simple crawler programs. However, my demand is too simple. It is a little tricky to use scrapy, and the disadvantage is that it is too complicated to use, in addition, I do not like twisted very much. It is not natural to use Asynchronous frameworks implemented by various callbacks. A while ago, I came into contact with gevent.(I don't know why such a pure technical website will be in progress), not to mention that it is said to be of good per

The engine gets the first URLs to crawl from the spider and schedules them in the schedider, as requests.3. The engine asks the scheduler for the next URLs to crawl.4.
