The Browser: The New Battleground for Cybersecurity

The browser has emerged as the primary access point for mission-critical business applications across distributed digital environments. As reliance on SaaS platforms and cloud-based solutions intensifies, attackers are increasingly targeting the browser instead of traditional endpoints. A recent analysis by The Hacker News identifies six rapidly evolving browser-based attack techniques that pose significant risks to enterprise security. [Read the full article]

1. Phishing for Credentials and Sessions

Modern phishing campaigns have evolved beyond email. Attackers now use instant messaging apps, social media, SMS, and even SaaS platforms to deliver malicious links. These campaigns often bypass MFA using advanced phishing kits that mimic legitimate login pages and steal session tokens directly from the browser.

2. Malicious Copy & Paste (ClickFix, FileFix)

ClickFix-style attacks trick users into copying and executing malicious code via browser-based challenges. These attacks often masquerade as CAPTCHA verifications or error messages, leading users to unknowingly run commands in PowerShell or Terminal, resulting in infostealer malware infections.

3. Malicious OAuth Integrations (Consent Phishing)

Consent phishing involves tricking users into authorizing malicious third-party apps with elevated permissions. This method bypasses traditional login flows and MFA protections, allowing attackers to infiltrate platforms like Salesforce and access sensitive data.

4. Malicious Browser Extensions

Attackers are increasingly exploiting browser extensions to capture credentials and session cookies. Whether by creating new malicious extensions or hijacking existing ones, these tools can silently observe user activity and compromise business applications.

5. Malicious File Delivery

Files like HTML Applications (HTAs) and weaponized SVGs are being used to deliver phishing pages or redirect users to malicious content. These files often evade traditional detection methods and execute client-side attacks directly within the browser.

6. Stolen Credentials and MFA Gaps

Even basic attacks using stolen credentials remain effective, especially when MFA is not enforced across all applications. “Ghost logins” and poor SSO configurations leave organizations vulnerable to credential stuffing and account takeovers.
