Slapper worm spanks Apache servers
By John Leyden, The Register
A virulent Linux worm is creating an attack network on the Internet, security clearing house CERT warned this weekend.
Slapper exploits a previously-disclosed OpenSSL vulnerability, to create an attack platform for distributed denial-of-service (DDoS) attacks against other sites. The worm also has backdoor functionality, according to, security tools vendor ISS. It describes the malicious code as a variation of the much less virulent Apache "Scalper" BSD worm.
The OpenSSL server vulnerability exploit exists on a wide variety of platforms, but Slapper appears to work only on Linux systems running Apache with the OpenSSL module (mod_ssl) on Intel architectures.
The Slapper worm was first seen on Friday the 13th. Since then it has infected thousands of web servers around the world and continues to spread. By late last night 6,000 servers were infected with the worm, according to AV vendors F-Secure.
