Recently, we’ve been researching several threat actors operating in South Asia: Transparent Tribe, SideCopy, etc., that deploy a range of remote access trojans (RATs). After a hunting session in our malware sample repositories and VirusTotal while looking into these actors, we gathered a small collection of VBA code samples that eventually allowed us to connect certain IOCs to individual threat actors based on the final payload, victimology and submission locations.…

In our previous article “Mobile banking fraud: BRATA strikes again” we’ve described how threat actors (TAs) leverage the Android banking trojan BRATA to perpetrate fraud via unauthorized wire transfers.

In this article, we are presenting further insights, on how BRATA is evolving in terms of both new targets and new features, such as:

Capability to perform the device factory reset: it appears that TAs are leveraging this feature to erase any trace, right after an unauthorized wire transfer attempt.…

In December 2021, the ThreatLabz research team identified several macro-based MS office files uploaded from Middle Eastern countries such as Jordan to OSINT sources such as VT. These files contained decoy themes related to geo-political conflicts between Israel and Palestine. Such themes have been used in previous attack campaigns waged by the Molerats APT.…

At the end of 2021, we were made aware of a UEFI firmware-level compromise through logs from our Firmware Scanner, which has been integrated into Kaspersky products since the beginning of 2019. Further analysis has shown that a single component within the inspected firmware’s image was modified by attackers in a way that allowed them to intercept the original execution flow of the machine’s boot sequence and introduce a sophisticated infection chain.…
