This guide serves as a master reference detailing top antivirus scanning solutions, their key capabilities, optimal use cases, and implementation methodologies for securing website properties against compromise. Read on to fortify your online assets.
The Growing Menace of Web-Based Malware and Attacks
While endpoints grab headlines for ransomware and virus outbreaks, websites face an equally alarming onslaught. Recent stats paint a dire picture:
- 1 in 10 websites contain malware – Domain threat intelligence provider URLhaus
- 40% of small business websites contain vulnerabilities – Sucuri semiannual hacking report
- 300% increase in malicious domains from 2020-2021 – Security company Zscaler
Behind the numbers lies real danger – website infections repeatedly enable headline-grabbing cyber attacks and data breaches:
-
Widespread exploitation of vulnerable WordPress plugins enabled hosts to inject crypto miners on over 200,000 sites impacting end users worldwide
-
Attackers leveraged poisoned JavaScript libraries uploaded to public CDNs to distribute credential stealer malware to thousands of sites
-
A 2020 Magecart attack on ecommerce provider Volusion led to credit card skimming malware inserted across over 6,300 online shops
With threats rampant and multiplying, relying on manual security checks or legacy methods proves woefully inadequate for the website attack surface.
Automating antivirus security is crucial – integrating advanced malware scanning APIs arms admins while unlocking workflow efficiencies only possible at cloud scale.
Website Threat Vectors Targeted by Antivirus Scanning APIs
To secure web properties, its essential to understand potential attack entry points and payloads aimed at compromising infrastructure and visitors:
Vulnerable Plugins & Frameworks – Self-contained web app extensions vastly expand attack surface i.e. malicious WordPress plugins, npm packages
Dependabot Updates – Libraries/dependencies containing disclosed 0days quickly exploit those clinging to EOL versions
Credential Stuffing – Attacker dictionary attacks against public logins like WordPress, cPanel, webmail
Phishing Campaigns – Highly convincing spoofed interfaces tricking staff/visitors to input credentials
Code Injection – Inserting iFrame redirects, scripts via outdated web apps i.e. SQLi, RCE exploits
Spam SEO Campaigns – Scaling content scrapers/comment spam to infiltrate sites then poison PageRank
Insecure Forms – Website visitor input/uploads check inadequately enabling malware delivery via purification evasion
Through a single vulnerable webpage, attackers breach site infrastructure – or worse, enterprise data by pivoting internally after gaining an initial foothold.
While mustering internal expertise across these threat vectors proves incredibly challenging, website malware scanning APIs distill industry-wide security research into continuously updated detection engines anyone can access.
Understanding Website Antivirus API Capabilities
At their core, website malware detection APIs function similarly to antivirus software securing endpoint devices: signature definitions and advanced heuristics identify threats for active blocking or alerting to admins for remediation.
However, specialized web scanning solutions focus on protecting against server-side and browser-based threats. This includes malware payloads in distributed platform backend code, scripts loaded through web pages, dangerous links being accessed by visitors, and more.
Deploying commercial website malware scanners as an overlay to production environments provides fulsome security visibility far surpassing traditional WAF or endpoint antivirus. Capabilities include:
Continuously Updated Threat Database – Community and commercial contributors supply malicious script signatures, suspicious URL blacklists, known vulnerable platform signatures, and emerging attack indicators to rapidly identify compromised assets.
Vulnerability Scanning – Many engines provide web application scanning functionality spanning OWASP Top 10 flaws to detect potential pathways injecting unwanted code and scripts into sites.
Behavioral Analysis – Advanced solutions emulate visitor workflows using machine learning for detecting malicious activity and payloads delivered through legitimate interfaces i.e. phishing forms capturing input.
Automated Scan Scheduling – Scan individual sites or entire portfolios on a fixed interval to meet compliance requirements and interdict threats.
Passive Monitoring – Analyze network traffic, infrastructure activity logs for indicators of compromise warranting further investigation separate from active scanning.
Root Cause Analysis – Review forensic snapshots of malware infrastructure communication patterns, pivot points, visitor infections facilitating remediation.
SIEM Integration – Sync discoveries with security event and information management dashboards to consolidate threat intel feeds.
Automated Ticketing – Generate alerts triggering proprietary workflows or using hooks to create tasks in PSAs/ITSMs to assign investigation tasks.
The breadth of protection website antivirus APIs confer make them a baseline requirement for securing online properties at any scale.
