A single click on a seemingly harmless link during a morning coffee break can quietly compromise an entire corporate network. For many business owners and managers, the browser has replaced the email inbox as the most common entry point for cybercriminals. Malicious websites, infected ads, and rogue browser extensions are no longer rare—they are part of everyday business risks.
This blog explains why browser-based attacks are now the preferred method for hackers, the methods they use, and most importantly, how businesses can defend themselves. You will see real-world examples, industry statistics, and practical measures you can adopt today. We will also share why Transputec is trusted by organisations to secure their systems against these evolving threats.
What are Browser-Based Attacks?
Browser-based attacks refer to cyber threats that exploit vulnerabilities in web browsers or their extensions to infiltrate devices and networks. Hackers leverage browsers’ ubiquity, targeting users through malicious websites, deceptive ads, drive-by downloads, and compromised plugins.
These attacks can sidestep firewalls and antivirus tools, making them exceptionally dangerous—especially with hybrid and remote work shifting so much business activity online.
Types of Browser-Based Attacks to Watch Out For
1. Phishing via Browser Windows
Phishing attacks have adopted new sophistication. Instead of suspicious emails, attackers now craft credible-looking popups, fake login pages, or exploit autofill data directly within browsers. According to IBM, phishing caused 16% of all breaches in 2023—many executed through browsers.
2. Drive-by Downloads
Just opening a webpage can infect a system if the site hides malicious scripts. Drive-by downloads exploit browser and plugin vulnerabilities, often requiring no user action. 2024 saw a 35% rise in drive-by incidents worldwide.
3. Malicious Extensions
Cybercriminals increasingly hide malware inside browser extensions. Once installed, these extensions can read keystrokes, monitor activity, and even redirect users to phishing sites.
4. Cross-Site Scripting (XSS)
XSS attacks inject malicious code into legitimate websites, compromising browsers through seemingly safe interactions. This technique is used in over 20% of web application attacks.
5. Man-in-the-Browser (MitB)
MitB attacks manipulate browser functions to intercept data or session tokens—especially dangerous for online banking and corporate portals.
The Business Impact of Browser-Based Attacks
Browser-based attacks cost companies millions—medium-sized businesses suffer average losses of £120,000 per breach. The aftereffects include:
Data theft: Customer and employee records exploited.
Downtime: Systems unusable for hours or days.
Regulatory fines: Failure to comply with GDPR or other standards.
Damaged reputation: Customers lose trust after breaches.
Empirical evidence underscores a sharp rise—browser vulnerabilities accounted for 48% of critical infrastructure incidents last year.
Why Traditional Defences Fail Against Browser-Based Attacks?
Many SMBs and enterprises rely on firewalls and endpoint antivirus, but browsers slip through the cracks:
Browsers frequently process external content—adverts, JavaScript, links—making them a common entry point.
Many security tools lack granular browser monitoring.
Employees regularly install extensions and visit new sites, heightening risk.
Recent surveys indicate that only 23% of companies use dedicated browser security tools, leaving 77% exposed to advanced threats.
Expert Strategies to Prevent Browser-Based Attacks
1. Harden Browser Settings
Disable unnecessary plugins, restrict pop-ups, and enforce strict site-permission policies. Google, Mozilla, and Microsoft frequently release patches—keep browsers updated.
2. Deploy Browser Isolation
Tools like remote browser isolation run web sessions in isolated containers, shielding local devices from potential infections.
3. Monitor and Audit Extensions
IT teams should regularly review installed extensions and enforce whitelisting. Automated scanning can detect suspicious behaviour.
4. Employee Awareness Training
Staff educated about browser-based attacks are 50% less likely to click suspicious links or install unknown extensions.
