How Can Businesses Defend Against Password Spraying Attacks? - ICSS

Introduction

Many different sorts of assaults are being used by attackers to compromise business-critical data. Zero-day attacks, supply chain attacks, and other types of attacks are examples. However, one of the most prevalent ways for hackers to gain access to your environment is through password compromise. In this blog we will speak How can businesses defend against Password Spraying attacks.

The password spraying attack is a specific type of password attack that can be used to compromise your system. Let's take a closer look at the password spraying assault and how businesses may avoid it.

How Can Businesses Defend Against Password Spraying Attacks

Be wary of credentials that have been compromised

Is it possible that your credentials have been compromised, putting your environment at risk? Yes! Compromised credentials allow an attacker to use valid credentials to "walk through the front door" of your environment. They take over all of the compromised account's privileges and permissions to systems, data, and resources.

It's considerably worse when a privileged account gets hacked. Accounts with high levels of access, such as an administrator user account, are referred to as privileged accounts. To an attacker, these types of accounts are the "holy grail," as they typically contain the "keys to the kingdom" in terms of access.An attacker, for example, can use an administrator account to not only get access to systems, but also to construct backdoors and high-level accounts that are difficult to detect.

What is a password spraying attack

The password spraying attack differs from the brute force assault in that it uses a different approach. An attacker uses a brute force assault to try an infinite number of passwords against a single account in order to crack it. The attacker uses the password spraying attack to "spray" the same password across numerous accounts.

Microsoft Active Directory Domain Services (ADDS) and account lockout policies are used by many enterprises. Administrators can set the number of failed login attempts before the account is locked out for a specific period of time using the account lockout policy. Lockout policies, for example, limit the number of failed login attempts to a certain number, such as five. The benefit of password spraying is that it allows the attacker to spread the attack across numerous accounts, avoiding account lockouts.

Common passwords that are available as password defaults or in known or leaked password lists may be used by attackers to target an environment. If an attacker spreads these passwords across a large number of user accounts, they're bound to come across one that has a known, compromised, or default password.

Prevent password spraying attacks

Any credential compromise is unquestionably a cybersecurity incident that businesses must avoid at all costs. Password spraying is another tactic in cybercriminals' attack armoury for gaining access to valuable or sensitive data. What precautions can businesses take to protect themselves from password-spraying assaults in particular?

There is no single "silver bullet" that can prevent all forms of attacks, as there is with many other cybersecurity dangers. Password security, on the other hand, necessitates a multi-layered solution that incorporates numerous mitigations. So, what exactly do these mitigations entail?

Account lockout regulations should be enforced. Restricting the number of failed password attempts.
Good password hygiene is enforced by effective password regulations.
Use password protection that has been hacked.
Multi-factor authentication should be implemented.

Concluding:

This was about how can business defend against password spraying attacks. There are Credential theft that is a serious threat to businesses, resulting in more expensive and time-consuming data breaches. Password spraying attacks are frequently used by attackers to exploit accounts with known passwords and circumvent the password lockout policy.

Specops Password Policy assists enterprises in implementing the best practises required for a modern cybersecurity posture. Beyond the core Active Directory functionality, it adds compromised password protection, password dictionaries, and strong password policy capabilities.

Furthermore, its breached password protection solution now incorporates live attack data, which protects enterprises from real-time password spray attacks.
