What Happens When A Host Suspends Your Website

Your website is offline and in its place is a message that says “Please contact your hosting provider for details.” Panic sets in, what does this mean? Why is this happening? How do I get the website back online? These questions and more begin to race through your mind.

Let’s start with what this means.  Your website has been suspended, which means the hosting provider has temporarily taken it offline. Website hosts often suspend websites for a myriad of reasons ranging from malware to spam.  They suspend websites when needed  to protect their servers that host tons of other websites, so they don’t get infected too.

Why is it happening?  Unfortunately, thousands and thousands of websites are infected every day and yours was one of them.  In fact, websites experience an average of 59 attacks per day, which is more than 21,500 per year.

How To Check Your Website For Malware

As cybercrime grows and evolves, malware remains a constant weapon in a cybercriminal’s armory. Malware, short for malicious software, is created with the intent of causing harm to a website or computer. Website malware can be used to steal sensitive customer information, hold websites for ransom, or even take control of the website itself. In many cases, victims of malware may not realize they’ve been attacked until it’s too late.

Over one million new malware threats are released daily, so knowing what you can do to check for and combat malware is essential for all website owners. To protect your website, it is critical to take matters into your own hands and become proactive about website security. There are two primary ways to do this; the first is by learning to check for signs of malware manually.

Tolly Test Highlights Web Application Security Need

 24/7

Who works 24/7? Not you, I hope – but hackers around the globe are busy trying to compromise systems 24 hours a day, seven days a week. “Next-gen” is not just a convenient marketing term, it is very accurate label for new types of threats and new types of solutions designed to counter those threats.

The basic nature of PC and server (aka “endpoint”) security and threats to same had not changed in many years. For years, the enemy would be the rogue program (.EXE) or Word macro that would find its way on to our system and either destroy our data or perhaps surreptitiously take control of our system either to steal our data or add our system to its army of drones – or both.

The traditional endpoint security solution would rely on its researchers to learn the digital fingerprints – usually referred to as the signature – of the virus. Upon detection, the entire offending program or macro would be isolated (quarantined) and, ultimately, deleted.

How To Look For Malware In Website Files

It can come as quite a surprise when a site owner is notified that their site has been compromised with malware. After the shock wears off, and the immediate impact understood, it’s important to take stock of what has actually happened behind the scenes and then clean it up. The best advice anyone can give you is to make frequent, downloaded backups of your site in the event something happens to the live version so that the clean backup can replace the live, hacked version.

But what if there is no clean, viable backup available? In a world where websites have hundreds, if not thousands of files, how can any one person go about cleaning out an infection in just a small number of those files? In this two part series, we’ll talk about how to look for malware in both files and databases and give a couple examples of what to be on the lookout for.
