404 scanning Concept
404 scanning is automated probing of missing URLs to find leftovers, backups, and known vulnerable paths.
404 scanning is automated probing of missing URLs to find leftovers, backups, and known vulnerable paths.
404 scanning - published by Larsik Corp
Bots do not only hit the homepage. They request thousands of paths that never existed: old plugin folders, .env backups, wp-config.php.bak , known exploit URLs. Each miss is a 404 that still costs PHP or server work. On cheap hosting, that noise shows up as slow sites and higher bills.
404 scanning - published by Larsik Corp
Account takeover Concept
Account takeover is when an attacker gains control of a legitimate user account and can act as that user.
Account takeover is when an attacker gains control of a legitimate user account and can act as that user.
Account takeover - published by Larsik Corp
If an Administrator account is taken over, the attacker can install plugins, create more admins, and plant backdoors. Takeover often starts with a reused password, a phishing page, or a session theft, not a clever zero-day.
Account takeover - published by Larsik Corp
Application passwords Concept
Application passwords are per-app credentials WordPress can issue so integrations authenticate without using your main password.
Application passwords are per-app credentials WordPress can issue so integrations authenticate without using your main password.
Application passwords - published by Larsik Corp
Mobile apps, CLI tools, and automations often need API access. Application passwords give them a revocable secret instead of storing the real admin password in a third-party service. They still carry the user’s capabilities. An app password on an Administrator is still administrator-level power if it leaks.
Application passwords - published by Larsik Corp
Assume breach Concept
Assume breach means designing as if an attacker may already have a foothold, so detection and recovery matter as much as prevention.
Assume breach means designing as if an attacker may already have a foothold, so detection and recovery matter as much as prevention.
Assume breach - published by Larsik Corp
Perfect prevention fails eventually: a zero-day plugin hole, a phished editor, a vendor compromise. Teams that only “lock the door” freeze when something slips through. Assume breach means you can still answer what changed, restore cleanly, and hunt persistence.
Assume breach - published by Larsik Corp
Backdoor Concept
A backdoor is hidden access an attacker leaves so they can return without the original vulnerability.
A backdoor is hidden access an attacker leaves so they can return without the original vulnerability.
Backdoor - published by Larsik Corp
Cleaning “the obvious malware file” while leaving a backdoor means reinfection days later. Backdoors hide in themes, mu-plugins, uploads with double extensions, or database options that eval code on every request.
Backdoor - published by Larsik Corp
Brute Force Concept
A brute-force attack tries many passwords or tokens until one works, usually against the login form.
A brute-force attack tries many passwords or tokens until one works, usually against the login form.
Brute force - published by Larsik Corp
WordPress exposes a public login URL on most sites. Bots can hit wp-login.php and xmlrpc.php all day with guessed passwords. One weak Administrator password is enough for a full takeover.
Brute force - published by Larsik Corp
Core file integrity Concept
Core file integrity is the assurance that WordPress core files match known-good versions and have not been tampered with.
Core file integrity is the assurance that WordPress core files match known-good versions and have not been tampered with.
Core file integrity - published by Larsik Corp
Attackers sometimes patch a core file so their backdoor loads on every request. The site can look fine in wp-admin while wp-includes is no longer stock WordPress. Comparing core to official hashes catches that class of persistence even when malware signatures miss it.
Core file integrity - published by Larsik Corp
Credential stuffing Concept
Credential stuffing replays usernames and passwords stolen from other breaches against your login.
Credential stuffing replays usernames and passwords stolen from other breaches against your login.
Credential stuffing - published by Larsik Corp
People reuse passwords. When another site leaks a list, attackers try those same pairs on WordPress. They are not guessing letter by letter. They are checking whether your users recycled a password from a breach dump.
Credential stuffing - published by Larsik Corp
CSRF Concept
CSRF tricks a logged-in browser into sending a request the user did not mean to send.
CSRF tricks a logged-in browser into sending a request the user did not mean to send.
CSRF - published by Larsik Corp
If an Administrator is logged in and visits a malicious page, that page can try to submit forms to wp-admin as the admin. WordPress core uses nonces to stop most of this. Custom plugins that skip nonce and capability checks stay risky.
CSRF - published by Larsik Corp
CVE Concept
A CVE is a public identifier for a known cybersecurity vulnerability tracked in shared databases.
A CVE is a public identifier for a known cybersecurity vulnerability tracked in shared databases.
CVE - published by Larsik Corp
When a plugin hole goes public, it usually gets a CVE ID (and sometimes several related IDs). Scanners, hosts, and news posts use that ID so everyone means the same bug. Your job is not to memorize CVSS charts. It is to see whether your installed version is affected and whether a fixed release exists.
CVE - published by Larsik Corp
DDoS Concept
A DDoS attack floods a site or its infrastructure with traffic so legitimate visitors cannot get through.
A DDoS attack floods a site or its infrastructure with traffic so legitimate visitors cannot get through.
DDoS - published by Larsik Corp
Even a cheap flood can knock shared hosting offline. Application-layer floods aim at login, search, XML-RPC, or heavy plugin endpoints so a little traffic does a lot of damage. A security plugin alone cannot absorb a large network flood; that belongs at the CDN or host edge.
DDoS - published by Larsik Corp
Defense in depth Concept
Defense in depth stacks multiple controls so one missed update or weak password is less likely to end in disaster.
Defense in depth stacks multiple controls so one missed update or weak password is less likely to end in disaster.
Defense in depth - published by Larsik Corp
There is no single “secure plugin” checkbox. Updates, backups, 2FA, a WAF, monitoring, and least privilege each catch different failures. Layers turn brittle security into something that survives a bad week.
Defense in depth - published by Larsik Corp
Event logging Concept
Event logging records security-relevant actions so you can see what changed and when.
Event logging records security-relevant actions so you can see what changed and when.
Event logging - published by Larsik Corp
When something goes wrong, memory is a bad forensic tool. A timeline of logins, plugin installs, option changes, and new users answers “who did that?” without guessing from a backup dump.
Event logging - published by Larsik Corp
False negative Concept
A false negative is a real security problem that a tool or process failed to detect.
A false negative is a real security problem that a tool or process failed to detect.
False negative - published by Larsik Corp
A green “no malware found” badge feels great. It is not proof the site is clean. New backdoors, clever obfuscation, and database-only injections get missed. Pair scanners with integrity checks, logs, and human review when symptoms disagree with the report.
False negative - published by Larsik Corp
False positive Concept
A false positive is an alert that looks like a problem but turns out to be benign after review.
A false positive is an alert that looks like a problem but turns out to be benign after review.
False positive - published by Larsik Corp
Scanners and WAFs err on the side of caution. Treating every flag as malware wastes hours. Ignoring every flag because “tools cry wolf” is how real infections linger. The skill is verification, not blind trust or blind dismissal.
False positive - published by Larsik Corp
File integrity monitoring Concept
File integrity monitoring checks whether important files changed compared with a known-good baseline.
File integrity monitoring checks whether important files changed compared with a known-good baseline.
File integrity monitoring - published by Larsik Corp
Attackers often tweak a core file, drop PHP under uploads/ , or quietly edit wp-config.php . Integrity checks catch those edits even when a signature scanner has never seen that exact payload.
File integrity monitoring - published by Larsik Corp
File upload vulnerability Concept
A file upload vulnerability lets an attacker place a dangerous file on the server, often leading to a webshell.
A file upload vulnerability lets an attacker place a dangerous file on the server, often leading to a webshell.
File upload vulnerability - published by Larsik Corp
WordPress sites upload media all day. When a form or plugin fails to validate type, size, or path, attackers upload .php (or double extensions) and browse to it. That is one of the most common ways webshells land.
File upload vulnerability - published by Larsik Corp
Incident response Concept
Incident response is the structured process of detecting, containing, cleaning, and learning from a security incident.
Incident response is the structured process of detecting, containing, cleaning, and learning from a security incident.
Incident response - published by Larsik Corp
When a site is hacked, random clicking makes things worse. A simple response order protects visitors, preserves evidence, removes persistence, and closes the door. You do not need a Fortune 500 playbook. You need a one-page checklist you will actually follow.
Incident response - published by Larsik Corp
Least privilege Concept
Least privilege means each user and integration gets only the access required for their job, nothing more.
Least privilege means each user and integration gets only the access required for their job, nothing more.
Least privilege - published by Larsik Corp
Every Administrator account is full keys to the kingdom. Freelancers, interns, and old agency logins with admin rights turn a small phishing win into a full takeover. Least privilege shrinks that blast radius before anything goes wrong.
Least privilege - published by Larsik Corp
Login protection Concept
Login protection is the set of controls that harden the WordPress login against bots and credential attacks.
Login protection is the set of controls that harden the WordPress login against bots and credential attacks.
Login protection - published by Larsik Corp
wp-login.php is the front door on almost every site. Bots do not care how small your blog is. Real protection is rate limits, lockouts, 2FA, and watching successes after failure spikes. Renaming the login URL alone is security theater.
Login protection - published by Larsik Corp
Malware Concept
Malware on WordPress is unwanted code that steals data, spam-sends, redirects visitors, or keeps a backdoor open.
Malware on WordPress is unwanted code that steals data, spam-sends, redirects visitors, or keeps a backdoor open.
Malware - published by Larsik Corp
Infected sites lose trust, trip Safe Browsing warnings, and can hurt visitors. Deleting the one ugly PHP file often fails because a backdoor, cron job, or database option puts it back. That “it returned overnight” pattern is common.
Malware - published by Larsik Corp
Nulled plugin Concept
A nulled plugin is an unauthorized, usually modified copy of a paid plugin that often includes malware or backdoors.
A nulled plugin is an unauthorized, usually modified copy of a paid plugin that often includes malware or backdoors.
Nulled plugin - published by Larsik Corp
“Free Pro download” sites do not remove the license check out of kindness. They often add webshells, spam injectors, or phone-home code. You trade a license fee for a persistent compromise that can outlive the plugin you thought you wanted.
Nulled plugin - published by Larsik Corp
Phishing Concept
Phishing tricks people into handing over credentials or installing malware by impersonating a trusted party.
Phishing tricks people into handing over credentials or installing malware by impersonating a trusted party.
Phishing - published by Larsik Corp
Attackers email “your site is hacked, log in here” or “WordPress needs urgent verification.” The fake page captures the password. 2FA helps a lot, but rush and fear still win when people click before they think.
Phishing - published by Larsik Corp
Plugin supply chain Concept
Plugin supply-chain risk is when trusted plugin code or updates become a path for attackers.
Plugin supply-chain risk is when trusted plugin code or updates become a path for attackers.
Plugin supply chain - published by Larsik Corp
You inherit the security of every plugin author you install. Abandoned plugins, stolen publisher accounts, and pirated “nulled” packages keep showing up in incident reports. The update you clicked can be the delivery path.
Plugin supply chain - published by Larsik Corp
Privilege escalation Concept
Privilege escalation is gaining higher access than intended, such as a subscriber becoming an administrator.
Privilege escalation is gaining higher access than intended, such as a subscriber becoming an administrator.
Privilege escalation - published by Larsik Corp
A bug that lets a Subscriber update options or upload PHP is effectively a full site takeover. Many plugin CVEs are labeled “authenticated privilege escalation.” Spam registrations plus one of those bugs is a common combo.
Privilege escalation - published by Larsik Corp
Rate limiting Concept
Rate limiting caps how often an action can happen from an IP or account, which slows automated abuse.
Rate limiting caps how often an action can happen from an IP or account, which slows automated abuse.
Rate limiting - published by Larsik Corp
Without limits, bots can try thousands of passwords per hour against wp-login.php and xmlrpc.php . That burns server resources and raises the odds that a weak password eventually works. Soft limits turn the spray into a slow, noisy process you can detect and block.
Rate limiting - published by Larsik Corp
Remote code execution Concept
Remote code execution is a vulnerability that lets an attacker run attacker-controlled code on the server.
Remote code execution is a vulnerability that lets an attacker run attacker-controlled code on the server.
Remote code execution - published by Larsik Corp
RCE is near the top of the severity ladder. If a plugin or theme flaw lets someone execute PHP or shell commands, they can drop a webshell, read wp-config.php , or pivot further. Public RCE CVEs get scanned quickly. Treat them as drop-everything updates.
Remote code execution - published by Larsik Corp
REST API Concept
The WordPress REST API is an HTTP JSON interface at /wp-json/ used by the editor, apps, and many plugins.
The WordPress REST API is an HTTP JSON interface at /wp-json/ used by the editor, apps, and many plugins.
REST API - published by Larsik Corp
/wp-json/ is how the block editor and countless plugins talk to WordPress. It is also a discovery surface: user enumeration, authenticated routes, and plugin endpoints that forget capability checks. Killing the entire REST API often breaks Gutenberg. The job is to understand what you expose, not to yank the fuse blindly.
REST API - published by Larsik Corp
Scheduled scanning Concept
Scheduled scanning runs security checks automatically on a repeating timetable and can alert you to new findings.
Scheduled scanning runs security checks automatically on a repeating timetable and can alert you to new findings.
Scheduled scanning - published by Larsik Corp
Manual scans only happen when someone remembers. Attackers and new CVEs do not wait for your Monday checklist. A schedule turns scanning into a habit: malware, vulnerabilities, or integrity drift show up in email or the dashboard while you are busy elsewhere.
Scheduled scanning - published by Larsik Corp
Security audit Concept
A security audit is a structured review of a site’s risks, misconfigurations, and recommended fixes.
A security audit is a structured review of a site’s risks, misconfigurations, and recommended fixes.
Security audit - published by Larsik Corp
Gut feel is not a plan. An audit turns “we should be more secure” into ordered work: outdated plugins, leftover admins, missing backups, open XML-RPC, weak login controls. Agencies use the same pass before launch or after a scare.
Security audit - published by Larsik Corp
Security hardening Concept
Hardening is the set of configuration and process changes that make a site harder to abuse.
Hardening is the set of configuration and process changes that make a site harder to abuse.
Security hardening - published by Larsik Corp
Default WordPress is usable, not maximally strict. Hardening shrinks what attackers can touch: fewer plugins, tighter roles, locked file editing, current software, tested backups. It is different from security theater (rename the login URL and call it done).
Security hardening - published by Larsik Corp
Security headers Concept
Security headers are HTTP response headers that tell browsers how to treat your pages for safer defaults.
Security headers are HTTP response headers that tell browsers how to treat your pages for safer defaults.
Security headers - published by Larsik Corp
Headers will not patch a vulnerable plugin. They still reduce common browser-side risks: forcing HTTPS (HSTS), blocking easy clickjacking, tightening what scripts can run when you use CSP carefully. Many hosts and CDNs can send them without a plugin pile-on.
Security headers - published by Larsik Corp
Security theater Concept
Security theater is activity that feels protective but does not meaningfully reduce real risk.
Security theater is activity that feels protective but does not meaningfully reduce real risk.
Security theater - published by Larsik Corp
Renaming wp-login.php , hiding the generator meta tag, or stacking five overlapping “security” plugins can feel productive while admin passwords stay weak and backups stay untested. Attackers automate the boring holes. They do not need your version string.
Security theater - published by Larsik Corp
Session hijacking Concept
Session hijacking steals or guesses a valid session so the attacker acts as the logged-in user.
Session hijacking steals or guesses a valid session so the attacker acts as the logged-in user.
Session hijacking - published by Larsik Corp
Admin cookies are powerful. XSS, malware on a workstation, or cleartext HTTP can expose them. After a hijack, the attacker does not need the password until the session ends. That is why HTTPS, XSS patching, and salt rotation after incidents matter together.
Session hijacking - published by Larsik Corp
SQL Injection Concept
SQL injection tricks a database query into running attacker-controlled SQL, often through unsafe input handling.
SQL injection tricks a database query into running attacker-controlled SQL, often through unsafe input handling.
SQL injection - published by Larsik Corp
Plugins and custom code that build SQL with raw request data can expose posts, users, or the whole database. On WordPress, that usually means a vulnerable extension, not core itself. Public CVEs get automated fast.
SQL injection - published by Larsik Corp
SSL/TLS Concept
SSL/TLS encrypts traffic between browsers and your server so passwords and cookies are harder to sniff.
SSL/TLS encrypts traffic between browsers and your server so passwords and cookies are harder to sniff.
SSL/TLS - published by Larsik Corp
Login forms, cookies, and customer data should never ride cleartext HTTP. Browsers mark non-HTTPS sites as insecure, which hurts trust and SEO. HTTPS protects the pipe. It does not fix an outdated plugin with a public CVE.
SSL/TLS - published by Larsik Corp
Two-Factor Authentication Concept
Two-factor authentication (2FA) requires a second proof of identity after the password, such as an app code.
PREVENTSBrute Force
Two-factor authentication (2FA) requires a second proof of identity after the password, such as an app code.
Two-factor authentication (2FA) - published by Larsik Corp
Passwords leak from other sites, phishing, and shared agency logins. 2FA means the password alone should not open wp-admin . For site owners and agencies, it is one of the highest-value controls you can turn on in an afternoon.
Two-factor authentication (2FA) - published by Larsik Corp
Vulnerability Concept
A vulnerability is a weakness in software that attackers can abuse to break confidentiality, integrity, or availability.
A vulnerability is a weakness in software that attackers can abuse to break confidentiality, integrity, or availability.
Vulnerability - published by Larsik Corp
Most breaches start with a known vulnerable plugin or theme, not a brand-new zero-day against core. Automated scanners look for unpatched versions within hours of a public advisory. Severity and fixed-version notes tell you whether to update today or tonight.
Vulnerability - published by Larsik Corp
WAF Concept
A WAF filters HTTP traffic to block common web attacks before they reach WordPress.
PREVENTSSQL Injection
A WAF filters HTTP traffic to block common web attacks before they reach WordPress.
WordPress WAF - published by Larsik Corp
A WordPress-oriented WAF sits at the edge or in the app and stops noisy exploit probes, bad bots, and known attack shapes. It is not a substitute for updates. It buys time and cuts drive-by noise while you patch.
WordPress WAF - published by Larsik Corp
Webshell Concept
A webshell is a small script uploaded to the server that lets an attacker run commands through the browser.
A webshell is a small script uploaded to the server that lets an attacker run commands through the browser.
Webshell - published by Larsik Corp
One PHP file in uploads or a theme can give filesystem and database access. Attackers use webshells to plant more malware, steal dumps, or pivot to other sites on shared hosting. Cleanup that misses the shell (or the upload hole) invites reinfection.
Webshell - published by Larsik Corp
WordPress nonce Concept
A WordPress nonce is a short-lived token used to verify that a request was intentional, mainly to reduce CSRF risk.
A WordPress nonce is a short-lived token used to verify that a request was intentional, mainly to reduce CSRF risk.
WordPress nonce - published by Larsik Corp
Core and well-built plugins attach nonces to admin forms and AJAX calls so a random third-party page cannot easily forge those actions while you are logged in. A missing or unchecked nonce shows up in CVE write-ups constantly. A nonce is not encryption, and it is not a substitute for capability checks.
WordPress nonce - published by Larsik Corp
WordPress salts Concept
WordPress salts are secret keys in wp-config.php that help secure cookies, nonces, and related cryptographic operations.
WordPress salts are secret keys in wp-config.php that help secure cookies, nonces, and related cryptographic operations.
WordPress salts - published by Larsik Corp
AUTH KEY , SECURE AUTH KEY , and the other salts in wp-config.php make session cookies and nonces harder to forge. If those secrets leak (or you inherited a site with keys copied from a tutorial), attackers have an easier time with stolen cookies. Regenerating salts invalidates existing sessions. That is often what you want after a breach.
WordPress salts - published by Larsik Corp
WordPress user roles Concept
User roles group capabilities that decide what each account can do in WordPress, from reading to full admin.
User roles group capabilities that decide what each account can do in WordPress, from reading to full admin.
WordPress user roles - published by Larsik Corp
Roles are how WordPress encodes trust. Misassigned roles are a common root cause of “someone changed the site and we do not know who.” Administrator can install plugins and edit code paths; Editor usually should not.
WordPress user roles - published by Larsik Corp
wp-config.php Concept
wp-config.php holds database credentials, keys, and core WordPress settings for the site.
wp-config.php holds database credentials, keys, and core WordPress settings for the site.
wp-config.php - published by Larsik Corp
If wp-config.php leaks, attackers get database access and authentication salts. Malware also loves to inject PHP here because the file loads on every request. One quiet edit can persist long after you delete an obvious webshell.
wp-config.php - published by Larsik Corp
XML-RPC Concept
XML-RPC is an older WordPress API endpoint attackers often abuse for brute force and amplification.
XML-RPC is an older WordPress API endpoint attackers often abuse for brute force and amplification.
XML-RPC - published by Larsik Corp
xmlrpc.php can allow many password attempts in one HTTP request (multicall) and has been used in pingback-based floods. Plenty of modern sites do not need it. Leaving it open without limits is free attack surface.
XML-RPC - published by Larsik Corp
Cross-site scripting (XSS) Concept
Cross-site scripting (XSS) injects malicious JavaScript into pages that other users’ browsers will run.
Cross-site scripting (XSS) injects malicious JavaScript into pages that other users’ browsers will run.
Cross-site scripting (XSS) - published by Larsik Corp
Stored XSS in a comment, page builder field, or admin notice can run in another user’s browser. For admins, that can mean stolen cookies, forced actions, or malware shown to visitors. Reflected XSS often rides on crafted URLs in plugins.
Cross-site scripting (XSS) - published by Larsik Corp
Zero trust Concept
Zero trust treats every request as untrusted until verified, and limits what any one identity can reach.
Zero trust treats every request as untrusted until verified, and limits what any one identity can reach.
Zero trust - published by Larsik Corp
“We are on the office VPN so we are safe” does not match remote teams and cloud hosts. For WordPress, zero trust looks like strong identity checks, least privilege, and less surprise when a laptop or freelancer account goes missing.
