Overview
The LegalQloud campaign marks a significant evolution in the tactics employed by cybercriminals, showcasing a targeted approach to credential theft through sophisticated phishing techniques. Centered around impersonating reputable legal firms, this campaign has garnered attention for its unique methodology and the calculated exploitation of trust. By carefully crafting emails that lead victims to malicious websites, the attackers effectively manipulate users into believing they are interacting with legitimate entities. This strategy not only enhances the campaign’s credibility but also increases the likelihood of successful breaches, making it a formidable threat in the landscape of cybersecurity.
One of the defining features of the
LegalQloud campaign is its exclusive reliance on Tencent Cloud for hosting phishing pages. This choice allows the attackers to sidestep traditional security measures, such as URL categorization and allow-list controls, that are commonly employed to identify and block malicious sites. The URLs used in the campaign follow a consistent format—<law_firm>.region.myqcloud.com—where “<law_firm>” corresponds to the targeted legal entity. This precision in targeting, combined with the impersonation of trusted brands, reflects a meticulous planning phase aimed at optimizing the chances of credential harvesting.

How they operate
The LegalQloud phishing campaign operates through a well-orchestrated sequence of technical maneuvers designed to deceive victims into revealing their Microsoft credentials. At the core of this campaign is the use of sophisticated social engineering tactics that target individuals within high-value sectors, particularly legal, government, and financial institutions. By impersonating legitimate legal firms, the campaign exploits the trust typically associated with these entities, enhancing its chances of success. When victims receive a phishing email that includes a malicious link, they are lured into a false sense of security, believing they are interacting with a reputable organization.
Upon clicking the deceptive link, victims are redirected to a phishing site hosted on Tencent Cloud, utilizing URLs formatted as <law_firm>.region.myqcloud.com, where “<law_firm>” corresponds to the name of the targeted firm. This strategic use of cloud hosting not only allows the attackers to bypass traditional security measures, such as URL filtering and allow-list controls, but also provides a level of anonymity that makes detection more challenging. The choice of Tencent Cloud as a hosting provider further complicates the response from cybersecurity teams, as it is a legitimate service used by many organizations, making it difficult to classify the phishing sites as malicious without robust monitoring.
The phishing page itself is designed to closely mimic official Microsoft login portals, employing visual elements that reinforce its legitimacy. Once victims attempt to log in, their credentials are captured by the attackers. Additionally, the campaign employs code obfuscation techniques to hide its malicious intent, further complicating detection efforts by automated security systems. Menlo Security’s investigation highlighted that the attackers consistently used the domain “businesssummitsolution[.]com” as a gateway to direct victims to these malicious pages, demonstrating a systematic approach to orchestrating the attack. This technical precision, combined with the campaign’s targeted focus on high-ranking executives, underscores the evolving sophistication of credential phishing operations in today’s cyber threat landscape.
Moreover, the attackers’ choice to focus on stealing Microsoft credentials reflects a broader trend among cybercriminals to target widely used platforms, as access to these accounts can yield significant organizational intelligence and resources. By using established cloud services and sophisticated obfuscation techniques, the LegalQloud campaign not only exemplifies the current state of cyber threats but also serves as a cautionary tale for organizations about the importance of vigilance and robust security measures to counter such evolving tactics.
