W3LL oiled machine: Group-IB uncovers covert BEC phishing empire targeting Microsoft 365
W3LL oiled machine: Group-IB uncovers covert BEC phishing empire targeting Microsoft 365
The report details the operations of W3LL, a threat actor behind a phishing empire that has remained largely unknown until now. Group-IB’s Threat Intelligence and Cyber Investigations teams have tracked the evolution of W3LL and uncovered that they played a major role in compromising Microsoft 365 business email accounts over the past 6 years. The threat actor created a hidden underground market, named W3LL Store, that served a closed community of at least 500 threat actors who could purchase a custom phishing kit called W3LL Panel, designed to bypass MFA, as well as 16 other fully customized tools for business email compromise (BEC) attacks. Group-IB investigators identified that W3LL’s phishing tools were used to target over 56,000 corporate Microsoft 365 accounts in the USA, Australia and Europe between October 2022 and July 2023. According to Group-IB’s rough estimates, W3LL’s Store’s turnover for the last 10 months may have reached $500,000. All the information collected by Group-IB’s cyber investigators about W3LL has been shared with relevant law enforcement organizations. PDF Document

New phishing-as-a-service tool “Greatness” already seen in the wild
New phishing-as-a-service tool “Greatness” already seen in the wild
  • A previously unreported phishing-as-a-service (PaaS) offering named “Greatness” has been used in several phishing campaigns since at least mid-2022. Greatness incorporates features seen in some of the most advanced PaaS offerings, such as multi-factor authentication (MFA) bypass, IP filtering and integration with Telegram bots. * Greatness, for now, is only focused on Microsoft 365 phishing pages, providing its affiliates with an attachment and link builder that creates highly convincing decoy and login pages. It contains features such as having the victim’s email address pre-filled and displaying their appropriate company logo and background image, extracted from the target organization’s real Microsoft 365 login page. This makes Greatness particularly well-suited for phishing business users. * An analysis of the domains targeted in several ongoing and past campaigns revealed the victims were almost exclusively companies in the U.S., U.K., Australia, South Africa, and Canada, and the most commonly targeted sectors were manufacturing, health care and technology. The exact distribution of victims in each country and sector varies slightly between campaigns. * To use Greatness, affiliates must deploy and configure a provided phishing kit with an API key that allows even unskilled threat actors to easily take advantage of the service’s more advanced features. The phishing kit and API work as a proxy to the Microsoft 365 authentication system, performing a “man-in-the-middle” attack and stealing the victim’s authentication credentials or cookies.

Can Better Training Reduce the Success Rate of Phishing Attacks?
A review of Arun Vishwanath, “The Weakest Link: How to Diagnose, Detect, and Defend Users From Phishing Attacks” (MIT Press, 2022) Many elements of the cyber threat landscape have changed significantly over the past two decades. For one, the number of attackers has grown dramatically, aided by the increasing availability of hacking tools and services as commodities for purchase in online marketplaces. The value of the losses cyber criminals have been able to inflict on their victims has also grown, though the dollar estimates vary widely in absolute terms. In recent years, the popularity of ransomware has increased substantially, prompting the Biden administration to initiate an ongoing diplomatic effort to foster cross-border efforts to curb this dangerous form of cyber-enabled extortion.
