Spam, Malware and FTP cracks

This advisory warns that spam messages containing malicious URLs lead to Trojan infections that enroll victims into large spam/malware/DDoS botnets and expose personal data; attackers commonly compromise web servers by cracking or sniffing FTP credentials, so the report urges operators and ISPs to adopt encrypted file transfer protocols (SFTP/FTPS) and use secure FTP clients (e.g., FileZilla, PuTTY PSFTP) to mitigate the threat.
