How You Know Your Business Website Has Been Hacked?

A hacking attack could happen to any website that not paying attention or uploading security fixes on a regular basis. Hacking private and small or medium-sized businesses has become a profitable environment for many persons with significant IT skills. Unfortunately, many businesses and even contemporary website managers only detect a problem when it is too late, resulting in the loss of vital data or money even a company reputation and privacy.

How to Tell if Your Website Has Been Hacked

1. A warning sign from browser
If you notice an alert from Google Chrome indicating that your website has been hacked, they have most likely been hacked. When Google Safe Browsing blacklists your website, this warning appears. Google's blacklist is used by popular browsers such as Google Chrome, Mozilla Firefox, Safari, and Opera to display warning messages to visitors. Examine the Google notifications that appear when your website is attacked.

2. Website loads slower than usual
If you think your website is taking an unusually long time to load, it could be due to a lot of activity across your website or server. Malware may be using server resources. Therefore, if your website takes twice or more than normal to load, these are warning signals and double-check your server for unusual, or malicious activities.

3. Your email has been sent to spam
Was the number of replies to the previous newsletter unusually low? This may be due to an email being placed in the customer's spam folder. If a hacker sends a list of spam emails through your website, keep an eye on your marketing activities as your website may be blacklisted by your email provider.

4. The file has recently change
If you find that your core system files have changed recently, compare the files to previous versions to see what has changed. The attacker could have modified the file to execute malicious code, send spam emails, or create a backdoor on your website. If a file with a suspicious filename, a server-side script file (.php, .aspx, .py, etc.) exists in the upload directory, this is a strong indication that the website has been hacked.

5. Ads or pop-ups when you visit the website
If your website visitors are seeing spam ads or pop-ups, your website may have been compromised by cross-site scripting (XSS) or malicious code injection. Hackers make money from the number of times an ad is viewed. The Google Safe Browsing team will send you an email notifying you that they have detected socially engineered content on your website.

What to Do If You Suspect Your Website Is Hacked
