Witnessed after the attack site summary and lessons learned

I have to do a station some time ago, long ranked first, every day, see the article, the chain is updated daily, but some days that flow far fewer, go see the next log, found that users Click on a page when a direct jump to other sites, this site and my site is the same industry, the moment well done, as had been previously attacked things, so people immediately think of the site where the malicious code to change my , is a SEO means of attack, my site is more commonly used DEDECMS management system, management of these systems are generally used, there are many loopholes, many people know, I usually do not pay much attention to a class of patched things, the results do not on a careful shot.

I've had a similar experience in handling, so that problem, I immediately see the page source code and found no jump code, see the JS code has nothing to find, view the FTP user password, no problem It seems that people do not do too much damage must, not tamper with other parts of the site, I was to jump straight to that page, look at the code and found some to be encoded JS, and then find a corresponding database table , downloaded to restore the database, and then replace the code, and finally back to normal site. Of course this is not enough to know the site is now normal, but inevitably some dirty tricks in the back, so I can not just relax and find someone else to the site kind of Trojan horse and back to DEDECMS upgrade to the latest version, and then give the site marked the latest patch, do so only after more thorough to prevent falls from happening again.

just want to say that such a thing to do is to SEO website traffic, ranking, conversion rate well, but do they usually have many competitors, the competitors will use high quality normal way to fight with you, next up will mimic the way we update the site and layout, and then summarizes some of their characteristics to fight with us, but if you run into some of the more eye-bad people, Zaihen a little, maybe will use improper means to attack our site.

now more developed and popular networks, some of the more simple hacking techniques online estimate will have a little look, but there are many SEO thugs, specifically for a good website ranking attacks, especially some of the popular words, interest is relatively high, the way you block someone else rich, and attack your site is not surprising. I run into something like this is a relatively simple, not too big of an attack damage, but also relatively easy to find, but they tend to use those means of various, very hard to detect, and some are hard to find, leading to lower site right or can not access the site and the interests of our own great harm, so we must be careful embankment. Now I tell everyone I know some of the SEO to prevent attacks and some personal experience.

one, as I run into this, the use of site vulnerabilities on the site to modify the code or files, to the detriment of the interests of the site, such as shielded spiders, tampering ROBOT.TXT documents, case of this thing, as long as there usually pay attention to the development of the site, in the event of problems, react quickly, and then find the problem is relatively simple, little damage, modification is not difficult.

two, DDOS attacks, but also an attack I had encountered, are hacking techniques, due to the previous understanding of the relatively small, my site is crazy attack, the servers are in a paralyzed state, unable to access several days have passed, and I have been down the right website, then recover spent a month's time. DDOS translation called distributed denial of service attacks, is attacked by a number of DOS attack on a server source on the formation of a DDOS attack, DoS attack There are many ways, the most basic DoS attacks is the use of reasonable service request to take too much service resources, so that the server can not handle legitimate user commands.

Third, there is for search engines, and now the domestic search engine technology is not perfect, for some vandalism can not clearly determine, prone to manslaughter.

1, 301 Jump others using some spam or porn sites jump in our site search engine is easy to misunderstand our site, multi-point jump in the number of sites, might lead to lower our website the right.

2, to brush our web site traffic, it sounds not have a problem, brush flow better ah, but if traffic suddenly rose, then, can easily lead to the search engines pay attention to, will find cheat site , resulting in lower right or lower ranking.

3, the Web site frequently to submit to search engines, you know, generally we will be right on the site submit your site to the early search engines, to attract the attention of search engines, included to enhance the speed, but if you frequently submit to search engines, search engines frequently to run, and the site was not any update, it is easy for search engines have a bad impression, it may lead to a proliferation down the right.

4, on the site outside the chain to a large number of spam comments.

Fourth, write a large number of posts made in forums and blog, the content is posing as consumers on our website over the customer, and then talk about some of the ill or slander web site products, thus affecting the efficiency and the brand site reputation. I have come across this before, only more Jiaoren post to find a bad forum post or suppressed complaints moderators to delete that post.

five sites linked to the horse, the site will often pop up some ads, and search engine algorithm updates this year, and the punishment for such a great site, is likely to be down the right, so that website to find out in time when the bad code, delete.

final say is in the country, for its own sake, so some people are still dry, so usually have to be backed up to the site, the event will not encounter unexpected surprise, my own past too lazy to back up, then once hung several stations, these stations are only backed up on the site early, then no backup, and transmits it up, what articles are less than N, the customer is always open Web page 404, and included significant decline, it is a tragedy. So backup is necessary, but should always back up. But also a lot of attention to what their own website, especially ranked first, second site, to avoid being black.
