On a daily basis, spammers register thousands of new domains across multiple domain registrars, and take advantage of WHOIS privacy services to ensure that security researchers and anti-spam fighters will have hard time taking them down. So what can we do about it?
According to a newly released research by Knujon.com, proper screening could have prevented 67% of those abusive domain registrations.

With politically motivated DDoS (distributed denial of service attack) attacks proliferating along with the overall increase in the supply of managed “DDoS for hire” services, it’s time to get back the basics, and find out just what makes an average DDoS bot used by cybercriminals successful.
Continuing the “A peek inside…” series, in this post I’ll profile the Darkness X (Optima) DDoS bot, available for purchase at selected cybercrime-friendly online communities since 2009.

What happens when a host gets infected with malware? On the majority of occasions, cybercriminals will use it as a launch platform for numerous malicious activities, such as spamming, launching DDoS attacks, harvesting for fresh emails, and account logins. But most interestingly, thanks to the support offered in multiple malware loaders, they will convert the malware-infected hosts into anonymization proxies used by cybercriminals to cover their Web activities.
In this post, I’ll profile a newly launched service, offering thousands of malware-infected hosts as Socks4 and Socks5 servers for anonymizing a cybercriminal’s Web activities.
