DHCP malware is circulating the web

Hackers are targeting the Dynamic Host Configuration Protocol (DHCP) with a new form of malware, it has been claimed.

The protocol, which was introduced in the 1990s to make setting up networks easier, has always had fundamental security vulnerabilities, according to industry expert Sherri Davidoff.

Writing for Search Security, the IT industry expert said that there are many tried and tested solutions to improving DHCP security and protect against viruses, malware and Trojans –installing anti-virus software on client systems such as laptops is one way to boost security.

According to the original DHCP specification document, "in its current form is quite insecure. Unauthorised DHCP servers may be easily set up. Such servers can then send false and potentially disruptive information to clients such as incorrect or duplicate IP addresses".

Meanwhile, recent research by Trend Micro has shown that data-stealing malware is on the increase, with 52 per cent of all attacks now carried out by Trojans.
