If you’re running a WordPress site, now would be a good time to ensure you are using very strong passwords and to make sure your username is not “admin.” According to reports from HostGator and CloudFlare, there is currently a significant attack being launched at WordPress blogs across the Internet. For the most part, this is a brute-force dictionary-based attack that aim to find the password for the ‘admin’ account that every WordPress site sets up by default.
HostGator’s analysis found that this is a well-organized and very distributed attack. The company believes that about 90,000 IP addresses are currently involved. CloudFlare, its founder and CEO Matthew Prince told me earlier today, thinks the hackers control about 100,000 bots. As for the scope of the attack, Prince says that CloudFlare saw attacks on virtually every WordPress site on its network.
Huge attack on WordPress sites could spawn never-before-seen super botnet
Security analysts have detected an ongoing attack that uses a huge number of computers from across the Internet to commandeer servers that run the WordPress blogging application.
The unknown people behind the highly distributed attack are using more than 90,000 IP addresses to brute-force crack administrative credentials of vulnerable WordPress systems, researchers from at least three Web hosting services reported. At least one company warned that the attackers may be in the process of building a “botnet” of infected computers that’s vastly stronger and more destructive than those available today. That’s because the servers have bandwidth connections that are typically tens, hundreds, or even thousands of times faster than botnets made of infected machines in homes and small businesses.
“These larger machines can cause much more damage in DDoS [distributed denial-of-service] attacks because the servers have large network connections and are capable of generating significant amounts of traffic,” Matthew Prince, CEO of content delivery network CloudFlare, wrote in a blog post describing the attacks.
