TTL and how to check TTL

TTL – Time to live is a value that signifies how long should the data be kept before discarding. It is commonly used in computers. In the Domain Name System, it has a value in seconds (86 400 for a day, 43 200 for 12 hours and so on) that shows for how long, should a record be kept locally, before you need to make a new query to get this information. The TTL is set separately for the different records. They are set in the authoritative DNS server and the recursive DNS will keep the information depending on the predetermined time. This process of temporary having the record is called caching and the temporary stored data – DNS cache.

DDoS amplification attacks by Memcached

What is DDoS amplification attack?

These attacks usually use the UDP protocol. It is a simple connectionless communication model with a minimum of protocol mechanism. This means that one of the sides in the communication can send large amount to the other without restrictions. Without any confirmation and it doesn’t matter if the second side receive the data.

Due to the way the UDP protocol works, cyber-criminals use it to generate DDoS amplification attacks. The attacker sends a small UDP request with a spoofed IP address of the victim to public services.

The UDP protocol doesn’t require a connection verification between the parties. This is why the public services reply with the requested data to the IP address of the victim. As bigger is the data returned by exploited public service, bigger is the DDoS amplification factor.

In the past few years, hackers have exploited many public DNS resolvers and NTP servers to generate massive DDoS attacks against popular websites and services. Continue reading “DDoS amplification attacks by Memcached”
