Brazilian Trojans beyond borders

Brazilian cybercriminals have always been very active in the creation and dissemination of banking Trojans among their compatriots. But now they are redirecting their attacks beyond the borders of Brazil to target banks in Europe. In recent months we have seen several Trojans developed in Brazil attempting to attack financial institutions in Europe, especially in Spain and Portugal.

As a rule, European banks were attacked by sophisticated Trojan bankers like SpyEye and by Zeus gangs, but now they face an onslaught from Brazilian Trojans. Our statistics show the dissemination of a specific variant affecting customers in Brazil and Portugal:

Trojan-Banker.Win32.Banbra.akzy

Inside the code of this Trojan we can see the name of some of the Brazilian and Portuguese banks targeted in the attack:

In other similar Trojans we found a function capable of stealing credentials from Brazilian customers:

As well as customers of banks in Cape Verde and Spain:

In a malicious proxy script commonly used in MitB attacks detected by our heuristic engine, we can see a list of Brazilian banks redirected to a malicious host – and surprisingly, a bank from Portugal is also targeted in the attack:

All these Brazilian Trojans demonstrate that cybercrime has no borders!

APT trends report Q2 2021

This is our latest summary of advanced persistent threat (APT) activity, focusing on significant events that we observed during Q2 2021: attacks against Microsoft Exchange servers, APT29 and APT31 activities, targeting campaigns, etc.

LuminousMoth APT: Sweeping attacks for the chosen few

We recently came across unusual APT activity that was detected in high volumes, albeit most likely aimed at a few targets of interest. Further analysis revealed that the actor, which we dubbed LuminousMoth, shows an affinity to the HoneyMyte group, otherwise known as Mustang Panda.

WildPressure targets the macOS platform

We found new malware samples used in WildPressure campaigns: newer version of the C++ Milum Trojan, a corresponding VBScript variant with the same version number, and a Python script working on both Windows and macOS.

Ferocious Kitten: 6 years of covert surveillance in Iran

Ferocious Kitten is an APT group that has been targeting Persian-speaking individuals in Iran. Some of the TTPs used by this threat actor are reminiscent of other groups, such as Domestic Kitten and Rampant Kitten. In this report we aim to provide more details on these findings.
