BRATA is evolving into an Advanced Persistent Threat
BRATA is evolving into an Advanced Persistent Threat
Here we go with another episode about our (not so) old friend, BRATA. In almost one year, threat actors (TAs) have further improved the capabilities of this malware. In our previous blog post [1] we defined three main BRATA variants, which appeared during two different waves detected by our telemetries at the very end of 2021. However, during the last months we have observed a change in the attack pattern commonly used.

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.

An infostealer comes to town: Dissecting a highly evasive malware targeting Italy
An infostealer comes to town: Dissecting a highly evasive malware targeting Italy
Cluster25 researchers analyzed several campaigns (also publicly reported by CERT-AGID) that used phishing emails to spread an InfoStealer malware written in .NET through an infection chain that involves Windows Shortcut (LNK) files and Batch Scripts (BAT). Taking into account the used TTPs and extracted evidence, the attacks seem perpetrated by the same adversary (internally named AUI001).
