How to defend a Server from Malware with Bulletproof Hosting

bulletproof web hosting

Bulletproof hosting, also known as bulk-friendly hosting (for sending spam messages or mails in bulk), has been the holy grail of cyber attackers for a long time now. It refers to a service that hosting providers offer to usually endure possible cyber threats or disregard abuse complaints. 

What are Botnets?

Botnets were mainly developed because of the complexity involved in offering bulletproof hosting so that cyber attackers could continue with their work even though one of their control and command nodes gets affected by a bulletproof host.

What is the right way to defend against such malware? If you are not aware of how enterprises can safeguard themselves against malicious programs that use it as a part of their hacking plan, here’s a quick look into it. 

Apprehension About Bulletproof Hosting

Bulletproof hosting can be safeguarded by freedom of speech, but few oppressive authorities might make attempts to compel a bulletproof host to eradicate content that is offensive or critical to the authorities. Though, laws in few nations permit for greater speech freedom; bulletproof hosts depend on such laws to defend their business and the speech. With the advancements happening in cloud hosting and quick cloud server provisioning, it is easy for cyber attackers to devise their own bulletproof hosting operating on a standard cloud provider; it’s also possible for them to negotiate an account on an authorized cloud service provider.

 

In the recent past, cyber attackers have been showing great interest in making use of bulletproof hosting for sending phishing and spam hacks to be used as drop sites for hacked data. FlashPack exploit is a new kind of malicious program that makes use of bulletproof hosting sites for distribution malware.

It seems to be utilizing the sites like a framework to load various kinds of exploits. 

Challenges faced by Enterprise in Dealing with Malware

Enterprises may find it difficult to stop the malware source, but they certainly can exploit the same protections used for defending against the usual malicious programs to safeguard against malware that use bulletproof hosting. Such defenses require using a network-oriented anti-malware application or host-oriented anti-malware tools, having system upgrade with patches, and more. 

Moreover, it’s advised to make use of a web proxy to just permit connections that are approved and block domains that are registered newly since this is a possible indication of a hacker using bulletproof hosting. Though, enterprises might need to supervise before blocking right away so as to avoid blocking authorized connections. Furthermore, enterprises should make use of a risk intelligence feed for determining the hosts to be blocked. 

Moreover, DNS monitoring methods, which are used by cloud security providers, are a great way of blocking malevolent hosts. Since malicious programs use DNS for looking up IP addresses to link to sites hosted at bulletproof hosts, looking out for doubtful DNS lookups could aid in finding systems linking to malevolent site.

The DNS name lookup could be altered by the DNS server for redirecting a possibly affected endpoint to a secure site, alerting about the endpoint it was attempting to link to a malevolent site.
