Evading detection while spreading across the network has always been one of the primary objectives of malicious actors. A new wave of attacks that made use of ‘VBA Stomping’ tactic to hide malicious macros, has been uncovered by security experts. The campaign was active throughout January 2020 and relied on new backdoor malware called MINEBRIDGE to target the financial sector in the US.

The past 24 hours also witnessed a change in technique from RobbinHood ransomware operators. The attackers were found exploiting vulnerable GIGABYTE drives to install a second malicious and unsigned driver in Windows. The purpose behind this is to bypass security solutions while the ransomware continues with its infection process.

In another incident, Emotet trojan operators have been observed using phishing emails to trick email security gateways and target financial institutions in the US and the UK. The campaign, which is active since January, is now directed towards the Philippines, Spain, and India.
