DoS and DDoS attacks, among the most feared types of cyber attacks for businesses, will no longer be your nightmare. As of 2016, our company Netinternet has set a series of goals to provide all solutions that our customers may need in all areas related to internet technologies, and has begun implementing these goals. In this context, our AntiDDoS service with 500Gbps capacity against DoS and DDoS attacks has been opened for use.

What are DoS and DDoS?

DoS: Denial of Service — a cyber attack from a single point aimed at preventing service delivery by exhausting system resources or internet bandwidth of servers providing internet services.

DDoS: Distributed Denial of Service — the same concept but from multiple points simultaneously.

How Does the AntiDDoS Service Provide a Solution?

To solve DDoS and DoS attacks, having expensive and high-capacity physical firewall equipment is not enough; you also need internet bandwidth wide enough to handle the scale of incoming attacks. At this point, our company Netinternet receives service from providers located abroad with connections to many operators to provide the required high bandwidth. Our AntiDDoS service currently has a network capacity of 860Gbps and a protection capacity of 500Gbps — many times larger than the total internet traffic of many countries.

Since this large capacity is priced on a pay-as-you-use system, we can offer the AntiDDoS service to our users at very low costs.

Dear customers,

Upon requests from you, our websites Netinternet.com.tr, where we offer web hosting and domain registration services, and Ni.net.tr, where we offer data center, server rental, and hosting services, are being merged. After the merge, our website will be Netinternet.com.tr. Customers with membership on both websites will be able to manage all their services from a single control panel.

As a result of work that has been ongoing for approximately 1 month, the merge will take place on Saturday, September 6, 2014. During the operations, access to customer panels on both websites will be limited for a short period.

After operations are complete, you will be able to log in to the new customer panel with your existing user information through our new website. Sharing your positive or negative opinions with us after logging in to our new website and control panel is valuable to us in providing you with better service.

Dear Customers,

We are ending the cPanel promotion that customers using VPS Virtual Server services have been benefiting from since 2009. Under this promotion, the cPanel VPS license with a selling price of 29 TL was being provided to VPS virtual server service customers for 15 TL. Since 80% of customers using VPS virtual server service use the cPanel VPS license, which would create a 14 TL difference in the price they pay, we applied a fixed 14 TL discount to all VPS packages to eliminate this difference created by the end of the promotion.

New prices for our VPS Virtual Server service:

1 CPU, 1 GB Memory, 40 GB Disk Space, 500 GB Traffic, Monthly 35 TL VAT Included

2 CPU, 2 GB Memory, 80 GB Disk Space, 1000 GB Traffic, Monthly 64 TL VAT Included

2 CPU, 4 GB Memory, 100 GB Disk Space, 1000 GB Traffic, Monthly 85 TL VAT Included

Dear Customers,

Prices and features of VPS virtual server services have been changed. Accordingly, a 6 TL discount has been applied to all packages in the virtual server service with changed features. The discounts are also valid for existing customers; all existing customers except those whose new invoices have been generated will make their next payments at the new tariffs.

One of the common problems lately is SPAM being sent by infiltrating an account on the server. In this blog post, we will briefly touch on how to detect the source of SPAM on a server and what measures should be taken.

The fundamental source of the problem is script security vulnerabilities, especially on shared hosting servers, no matter how many security measures you take. Vulnerabilities in WordPress-based software and SPAM emails sent by infiltrating accounts of users who have not applied the security-fixing update have caused quite annoying problems with IP addresses getting blacklisted.

Developing technology provides today’s hackers with new opportunities. Currently, the most common work done by bots that hack accounts with script security vulnerabilities is opening PHP socket connections and sending SPAM emails directly through their own software without using the email service installed on the server, using all IP addresses attached to the server. This way, hackers can send SPAM until the IP is blacklisted using all IPs they can detect on the web hosting account they have captured.

System administrators who are unaware of this method generally immediately check the email service logs on the server to find which account is sending SPAM. But they cannot find any log records, because SPAM is not being sent through the email service installed on the server. The best method for detecting this on Linux servers is the netstat command.

Most Commonly Used Netstat Parameters

-n: Does not show IP RDNS output, enabling faster results

-t: Lists TCP connections without showing Unix socket connections

-u: Lists UDP connections without showing Unix socket connections

-p: Shows which program and PID number the listed connections are running under

The command we need is netstat -ntup. With the command netstat -ntup | grep :25, the application names next to PID numbers should be EXIM (on a cPanel server). If we see PHP instead of EXIM, we may be facing a problem.

To find the directory of the running PID file:

lsof -p PIDNUMBER

lsof -p PIDNUMBER | grep cwd

This way we can reach the directory where the PHP application using port 25 is running. The files placed by the hacker exploiting the script vulnerability will be directly visible in the directory.

To block TCP tunneling via SSH:

AllowTCPForwarding no

Add this to the SSH config file and restart the SSH service.

One of the best solution methods we want to share: In our own hosting network, we use SMTP RELAY servers for email sending. We enter a rule on the main switch that blocks access from all server IP addresses except the RELAY server we defined on the local network to port 25. This way, email sending is never done from outside the SMTP RELAY servers.

Existing Netinternet customers can activate similar ACL rules themselves from the IP Management section in their customer panels. When ACL-SMTP is active, port 25 of the servers is closed to the internet while remaining open on the local network.
