Background for this topic.
Authentication confirms the identity of users or systems before granting access to resources, typically using factors like passwords (knowledge), hardware tokens (possession), or biometrics (inherence). It establishes trust boundaries that prevent unauthorized entities from impersonating legitimate users or devices within networks and applications.
Weak authentication enables attackers to perform account takeover, privilege escalation, or lateral movement by exploiting stolen credentials, phishing, or replay attacks. Deploying multi-factor authentication (MFA) with independent factors significantly reduces these risks. Secure credential storage, regular rotation, and monitoring authentication logs for anomalies are critical defenses to detect and block unauthorized access attempts early in the attack chain.
Multifactor authentication is a good first step, but businesses should look to collect and analyze data to hunt for threats, manage identities more closely, and limit the impact of attacks.
Adversary-in-the-middle attacks can strip out the passkey option from login pages that users see, leaving targets with only authentication choices that force them to give up credentials.
Although not yet exploited in the wild, the max-critical authentication bypass bug could allow adversaries to take over unpatched Juniper Session Smart Routers and Conductors, and WAN Assurance Routers, the company warns.
Vulnerability Can Allow Authentication Bypass; No Evidence of Exploitation YetJuniper Networks released an out-of-band fix for a maximum-severity vulnerability that can allow hackers to bypass authentication in three Juniper products. The CVSS 10-rated bug could allow an attacker to take full control of a compromised system.
Juniper Networks has released out-of-band security updates to address a critical security flaw that could lead to an authentication bypass in some of its routers
Juniper Networks has released an emergency update to address a maximum severity vulnerability that leads to authentication bypass in Session Smart Router (SSR), Session Smart Conductor, and WAN Assurance Router products. [...]
