Detect and Deny Unsupported Request Methods in PHP

How to Detect and Deny unsupported HTTP request methods with PHP

While working on the current version of my PHP Firewall ( XS Firewall ), I wanted to include a way to restrict any requests made by a client that uses a non standard or unsupported HTTP request method to a PHP application.

The basic idea I had was to create a HTTP request method whitelist, and catch anything not in the whitelist. I'd no longer have to find bad bots or malicious users in my logs before I can block them.

A new bot called the XoviBot has been seen lurking around the site lately. Here's some information about where the XoviBot comes from, which just might help you decide what to do with it, when it visits your own site.

The XoviBot belongs to a company called Xovi GmbH, from Cologne Germany. They provide a set of services to webmasters advertised as a "SEO Controlling & Online Marketing Suite".

Content Scrapers Written by Moore

Hi all, here's another update on the latest Ahrefsbot IP ranges I've spotted recently targeting our sites.

Business must be going well for Ahrefs as once again they have expanded their operations, this time throughout the 37.58.100. IP range, from the Softlayer hosting company.

The latest attempts from the Ahrefsbot were blocked while trying to access login protected pages, which is what caught my attention.

Ads on Disney, Facebook, Guardian Lead to Cryptowall Ransomware

News Written by Moore

Emsisoft recently put out a malware alert on their blog about a widespread malware campaign on high profile websites that lead to Cryptowall.

Cryptowall is a variant of Cryptodefense, which is a ransomware program similar to the notorious Cryptolocker that encrypts all the files on your harddrive and demands payment to decrypt them.

So basically if you don't pay the ransom, you'll never get your files back. Even Police Stations have been hit by this malware and can't do anything about it.

Malware Alert: Malicious advertisements hosted on domains owned by Disney, Facebook, and The Guardian have been leading people to hacked websites that serve a file-encrypting ransomware called Cryptowall.

The Website Security plan provides access to a whole new range of blocklists which have been in the works for awhile now. These are new blocklists to protect your server or website from an ever growing number of threats and daily abuses.

The new web security lists include the Bad bots & Parasites blocklist, the Web Exploit blocklist to combat persistent site exploit scanners and a Hosts Spy / SEO Spybots blocklist to protect against domain and keyword analysis services who try to make money from the information they generate ( harvest ) from your site.
