IBM X-Force has been tracking the activity of ITG23, a prominent cybercrime gang also known as the TrickBot Gang and Wizard Spider. Researchers are seeing an aggressive expansion of the gang’s malware distribution channels, infecting enterprise users with Trickbot and BazarLoader.

In this article, IBM X-Force, together with Cylera analysts, addresses the growing number of campaigns that ITG23 is using to deliver proprietary malware, including distribution through other cybercrime groups that X-Force tracks as Hive0105, Hive0106 and Hive0107.
Earlier this year, ITG23 primarily relied on email campaigns delivering Excel documents and a call center ruse known as BazarCall to deliver its payloads to corporate users. However, starting around June 20 ..
