Password spraying is a stealthy cyberattack method that targets multiple user accounts using weak, commonly used passwords. Unlike traditional brute-force attacks that focus on a single account, password spraying tries one or two passwords across many accounts to avoid triggering lockout mechanisms. It’s an especially dangerous tactic because it exploits human error — weak passwords and reused credentials — making it a major threat to businesses across Western Sydney, including areas like Wetherill Park, Parramatta, and Blacktown.

This article will help you understand how password spraying works, how it differs from other attack methods, and what small businesses can do to detect and prevent it. We'll also look at real-world examples, best practices, and actionable strategies you can implement today with the help of BIT365.

What Is Password Spraying and How Does It Work?

Password spraying is a form of brute-force attack where cybercriminals attempt to access multiple user accounts using one or a few common passwords. This technique helps attackers bypass standard account lockout policies and remain undetected for longer periods.

Real-World Example

A mid-sized law firm in Parramatta experienced a breach after an attacker used "Winter2024!" across dozens of staff accounts. The attacker gained access to internal systems and sensitive legal files, costing the firm thousands in damages and compliance headaches.

Why It Works

• Many users still rely on simple, easy-to-remember passwords.
• Attackers use public data leaks and employee directories to build username lists.
• Automated tools allow for rapid testing without triggering alerts.

How Does Password Spraying Differ from Other Cyberattacks?

Password spraying stands apart from brute-force and credential stuffing in terms of tactics and detection evasion.

Traditional Brute-Force

Focuses on trying many passwords for one account, triggering account lockouts quickly.

Credential Stuffing

Uses known compromised credentials, testing them across various sites - highly effective when users reuse passwords.

Password Spraying

Tests a small set of common passwords (e.g., "Welcome123") against many accounts, often bypassing rate limits and lockouts.

How Can Organisations Detect and Prevent Password Spraying?

1. Implement Strong Password Policies

Use complexity requirements (uppercase, symbols, length) and enforce regular updates. Tools like 1Password or LastPass help users generate and store complex passwords securely.

2. Enforce Multi-Factor Authentication (MFA)

Adding a second layer of authentication (e.g., SMS, app-based codes) can block access even if a password is compromised.

3. Monitor Login Patterns

Deploy security information and event management (SIEM) tools to flag:

• Multiple login attempts from the same IP
• Logins to different accounts using the same password
• Off-hours login attempts

4. Conduct Regular Security Audits

Review logs, patch vulnerabilities, and evaluate password hygiene quarterly to stay ahead of potential attacks.

What Additional Measures Can Be Taken to Enhance Security?

Enhance Login Detection Systems

Invest in behavioural analytics software that flags unusual login patterns - such as a login to multiple accounts from a single location within minutes.

Educate Employees

Train staff across Blacktown and Campbelltown offices on phishing, password hygiene, and MFA benefits. Awareness is often your strongest line of defence.

Have an Incident Response Plan

If a breach occurs:

• Notify affected users immediately.
• Force password resets.
• Conduct a root cause analysis.
• Report and comply with relevant data privacy laws (such as the Australian Privacy Act).

Taking Action Against Password Spraying

Password spraying is not a hypothetical threat - it's already affecting small to mid-sized businesses throughout Western Sydney. Human error remains the most common entry point, making awareness and proactive security critical.
