Introduction
Phishing attacks continue to pose a significant threat to individuals and organizations worldwide. Analysts at SecneurX have recently conducted an in-depth analysis of a Microsoft phishing page, designed to deceive unsuspecting victims into revealing their login credentials. In this blog post, we delve into the details of this sophisticated attack, highlight the risks involved, and provide guidance on how to protect yourself from falling victim to such scams.
The Anatomy of the Phishing Page
The analyzed phishing page appears remarkably similar to the legitimate Microsoft login page, making it difficult for users to detect its malicious intent. Upon loading the page, it fetches image files from the authentic Microsoft server to create a convincing facade. However, behind the scenes, the page has been crafted to capture users' login credentials discreetly like shown in the image below.
In this blog post, we have taken the below sample for analysis

Data Exfiltration and Compromised Domain
Once an unsuspecting victim enters their password, the data is stealthily posted to a compromised domain controlled by the malware author. In this case, the compromised domain is "hxxps://heeni-investment.co.nz/cssv.php". It is important to note that the domain used for data exfiltration has been compromised and is under the control of malicious actors, amplifying the risks associated with this phishing campaign.
Understanding the Server Responses
Once the compromised domain receives the posted data, it responds with the message "KOSONG," which is currently configured to be the response as shown in the image below. It is important to note that the server can have different responses based on the HTML source code. These responses may include "VALID," "GAGAL," "KURANG," or "KOSONG," each with its own meaning within the context of the phishing attack.
The Risks and Implications
Phishing attacks of this nature have severe consequences, including unauthorized access to personal accounts, data breaches, identity theft, and even financial losses. The theft of Microsoft login credentials can lead to the compromise of sensitive information, unauthorized activities, and the potential for further attacks against both individuals and organizations.
Protecting Yourself Against Phishing Attacks
1. Stay Vigilant: Be cautious when interacting with emails, messages, or links that request your login credentials. Verify the legitimacy of the sender before providing any sensitive information.
2. Check the URL: Always double-check the URL of the login page to ensure it matches the official website. Look for subtle misspellings, variations, or unfamiliar domains that may indicate a phishing attempt.
3. Enable Two-Factor Authentication (2FA): Implementing 2FA adds an extra layer of security by requiring a second form of authentication, such as a code sent to your mobile device, in addition to your password.
4. Education and Awareness: Stay informed about the latest phishing techniques and best practices for online security. Regularly educate yourself and your employees on how to recognize and avoid phishing scams.
