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.…
BlueNoroff is the name of an APT group coined by Kaspersky researchers while investigating the notorious attack on Bangladesh’s Central Bank back in 2016.

Recently, the McAfee Mobile Research Team uncovered several new variants of the Android malware family BRATA being distributed in Google Play, ironically posing as app security scanners.
These malicious apps urge users to update Chrome, WhatsApp, or a PDF reader, yet instead of updating the app in question, they take full control of the device by abusing accessibility services.…
Cuba ransomware is an older ransomware, that has recently undergone some development. The actors have incorporated the leaking of victim data to increase its impact and revenue, much like we have seen recently with other major ransomware campaigns.
In our analysis, we observed that the attackers had access to the network before the infection and were able to collect specific information in order to orchestrate the attack and have the greatest impact.…
