Search engines may start flagging errors, and customers see a blank page instead of your business. In that moment, the pressure is real: What broke, and how do you get back online before the damage adds up? The good news is that most WordPress outages are fixable. In most cases, your site isn’t lost, it’s blocked by something like a plugin conflict, server hiccup, database error, expired domain, SSL problem, sudden traffic spike, or malware infection.

Data breach notification letters have become a familiar routine. They usually start with “We value your privacy” and offer a year of free credit monitoring. But the most important part is often hidden in the middle: A list of what actually got out. A leaked email address is not a leaked admin password. A hashed credential is not a session token. There is no universal post-breach checklist. The right response depends on the data exposed, so read the notice carefully and match your response to the level of exposure.

Online gambling spam thrives on dreams of easy money and high stakes. Beating the house at an exotic casino. Splitting sevens. Going all in on the flop. A baccarat dealer calling La grande! For most people, though, the reality falls far short of Monte Carlo and an Aston Martin. So they turn to online gambling. And bad actors harness that allure to create their scams. They think they’re buying credits at a hot new online casino. Continue reading What is online gambling spam and what can I do about it? at Sucuri Blog.

Most phishing advice is written for the person staring at a suspicious email. This guide is for the other kind of victim: The website owner whose legitimate site has been quietly turned into the attacker’s weapon. You didn’t send the message or build the fake login page. You just woke up to a browser warning, a suspended hosting account, or a polite note from someone’s security team asking why your domain is requesting Apple ID credentials.

WordPress powers over 40% of the web, which makes it one of the most attractive targets for Distributed Denial of Service (DDoS) attacks. If your site goes down for an hour, you lose revenue, search rankings, and visitor trust. If it goes down repeatedly, you lose much more. A DDoS attack floods your website with fake traffic until it slows to a crawl or crashes entirely. Unlike hacks that steal data, DDoS attacks are about disruption.

What is 2FA? Two-factor authentication (2FA) offers a second layer of security to help protect an account from brute force, phishing, and social engineering attacks. 2FA requires an extra step for a user to prove their identity, which reduces the chance of a bad actor gaining access to their account or data. And since notifications are sent to verify the initial authentication via username and passwords, it also gives users and business the ability to monitor for potential indicators of a compromise. Continue reading Why 2FA SMS is a Bad Idea in 2026 at Sucuri Blog.

If you own a WordPress website and ever encountered the “Not Secure” warning, you might have worried that visitors would perceive your site as spam or fraudulent. Not only does this warning impact user trust, but it can also create technical search issues when both HTTP and HTTPS versions of your pages remain accessible or when redirects, canonicals, and sitemaps point to different URL versions. Browsers show the visible security warning, while search engines rely on permanent redirects, canonical URLs, and updated sitemaps to understand your preferred HTTPS pages.
