Phishing attacks in 2025 are increasingly sophisticated, evading traditional detection by using MFA-bypassing phishing kits, and launching attacks that appear novel each time. Current phishing detection relies heavily on blocklists incorporating domains, URLs, and IPs identified post-attack, which fails to prevent initial phishing attempts. Attackers exploit disposable domains and dynamically change attack vectors, making traditional indicator-based detection methods ineffective. Phishing often involves email, but attackers are using multi-channel approaches to avoid detection, complicating the identification of malicious pages. New evasion techniques include CAPTCHAs and complex JavaScript, stymieing sandboxes and static analysis tools in identifying malicious content. Phishing's inherent post-attack detection nature delays effective responses, often allowing attackers to harvest credentials before being identified. A browser-based detection solution, where phishing detection occurs in real-time as the user interacts with the page, is proposed as the future to effectively combat phishing attacks. Push Security advocates real-time, browser-based phishing detection, claiming significant advantages in visibility and response over traditional methods.

Phishing attacks are increasingly leveraging identity-based techniques, with phishing-linked stolen credentials now the primary cause of breaches. Traditional detection controls like Secure Email Gateways and network layers are being bypassed by attackers using sophisticated methods such as malvertising and multi-channel attacks. Browser-based detection offers a new frontier in responsibility for phishing defense, focusing directly on the content within the browser environment. In-browser security tools can analyze dynamic web pages and JavaScript, enabling detection of tactics, techniques, and procedures (TTPs) instead of just indicators of compromise (IoCs). Real-time interception of phishing attempts is feasible with browser-based solutions that observe user interactions directly on malicious pages. Such advancements in detection from within the browser help shut down phishing attacks before they cause harm, contrary to the delayed response of non-browser solutions. Push Security's browser extension is highlighted as a proactive tool in real-time phishing prevention, offering comprehensive protection against varied identity attack techniques.

Russian-linked cyber actors are aggressively targeting entities tied to Ukraine and human rights, focusing on unauthorized access to Microsoft 365 accounts. They employ sophisticated social engineering tactics involving Microsoft OAuth 2.0 Authentication workflows to deceive victims into providing Microsoft-generated OAuth codes. The attackers use compromised identities, impersonating European political officials and leveraging platforms like Signal and WhatsApp to coordinate meetings and share malicious links. These tactics enable the attackers to generate Microsoft Authentication Tokens, gaining control over victims' Microsoft 365 accounts. The targeted attacks have been linked to several Russian threat groups, with potential connections to known entities like APT29. Methods involve redirecting victims to manipulated URLs that appear as legitimate Microsoft login portals, where the OAuth authorization codes are harvested. Once the OAuth code is shared, attackers can register a new device to the victim's Microsoft Entra ID, potentially gaining permanent account access. Organizations are advised to increase awareness of phishing attacks, audit newly registered devices, and tighten conditional access policies to mitigate these threats.
