Hello We’ve a dedicated server with SoYouStart with a few custom website and a few WordPress. For last few months we observed the server slows down and comes to life again only on restart. This almost happens daily and we have to restart server again every day. It looks like some memory issue or some processing on server using some malicious code. We got it checked once and were told that there are some code/files that mine cryptocurrency on server. We got it fixed and server worked fine for some days. However the same issue started coming again after a few days. We want some expert to do backup and then look into our server – check what is causing the time out errors or any other unwanted/malicious processing, and remove/fix all the code/files. Plus, also fix the underlying cause and put security measures in place on server, so that we don’t get any such issues again in future. Please only bid if you are expert and confident of fixing these kinds of issues, and also if you are certain of security measure you should be putting to completely prevent such issue in future. Great thanks.

Hello, I am simply a guru level Linux system administrator. Believe or not about one month ago i have performed a similar crypto-builder infected server. It was due to a vulnerable wordpress plugin and client had been tired of removing the files over and over again. I fixed the issue within less than 1 day and server is operating properly at the moment. In short, i am quite expert with identifying the possible vulnerabilities on servers and as you mentioned to fix the root cause issues to prevent them happening again. I can deploy several security measures after cleaning the server (like wordfence, CSF firewall, rootkit etc.) to proactively prevent malicious attacks. I guarantee that you would not face with the same problem at least for one year and if you do so i will refund all your costs but also perform any tasks necessary again. Kindly check my previously completed projects as well as my reviews to qualify my experiences. Thank you for your time in advance and hope to hear from you soon too, Thank you! Emre.

Kindly let me know what platform your site is hosted on. A thorough investigation of web server log will be required in contrast to any malicious code being executed from the server and if there is any rootkit/backdrop on the server which maybe being used for inject the code.

Hello Sir, This is my experience that if one infected file exists on your server then it will infect your server again and again. So I need to check each file and folder manually. Sir,I never use any software or any programming script or any scanner to find out malicious files or script on server. Because they can never give you 100% accuracy. But I will provide you 100% accuracy because I go through whole server manually and check each file and folder manually. I will also check your SQL file because I have found malicious script or suspicious script in SQL file many times. Thanks

hi, I think the issue that you have been experiencing will not easily fix in several days. This is honest. The reason why, I would like to list you several items ( and you can use them to discuss with others to double-check) - "It looks like some memory issue or some processing on server using some malicious code" -> you need to have an evidence what is causing the memory issue, not just "assume/looks" via your nice Web UI. You should look to OS level when running investigation tool like top, ps, read syslog, service logs... And this kind of investigation needs to do during the "slowness" time. So, if a person says you that it looks or maybe... without looking to the System level, you will not figure out the root of case - " We got it fixed and server worked fine for some days. However the same issue started coming again after a few days." Yeah, because you did not fix the root of case, it may have a zero day bug in your wordpress, apache/nginx, plesk/vestacp... setup and the bad guy can attack to gain permission to login... ANd you can clean up and they can inject your site again - "We want some expert to do backup and then look into our server " -> this is a task of system/devops/security Linux engineer. To complete to resolve your issue you should: - Have an experience guy to monitor what is consuming your resources (CPU or RAM, nginx/apache or mysql, or ...) - To have a tool to monitor your services to see when having a lot of http errors like 4xx, 5xx to block.. ...

Hi, This is what I'll do. 1. Backup server 2. Find malware by scanning with necessary tools (rkhunter etc) & by examining logs for any malware on the server. 3. Document & remove malware on the server. 3. Apply necessary software updates. Unfortunately the only way that you can be sure of the server being compromised in the future is by regularly patching & updating the software that runs on it. But I can check & verify your firewall rules and other setting that make your machine vulnerable. If you do not have a storage solution for the backups I can provide one for the duration of work for an additional fee. This bid is predicated on the server not requiring any major version updates, e.g. an Apache httpd web server upgrades that would require new configurations etc. would be out of scope.
