Seqrite, the enterprise arm of IT security firm Quick Heal Technologies, detected the new wave of Adwind Java Remote Access Trojan (RAT) campaign.
Researchers at Seqrite warned that if attackers are successful, they can take over the victim's device to steal sensitive data like SWIFT logins and customer details and move laterally to launch large scale cyberattacks and financial frauds.
According to the researchers, the Java RAT campaign starts with a spear-phishing email which claims to have originated from either the Reserve Bank of India or a nationalised bank.
The content of the email refers to COVID-19 guidelines or a financial transaction, with detailed information in an attachment, which is a zip file containing a JAR based malware Upon further investigation, researchers at Seqrite found that the JAR based malware is a Remote Access Trojan that can run on any machine which has Java runtime enabled and hence it can impact a variety of endpoints, irrespective of their base operating system.
Once the RAT is installed, the attacker can take over the victim's device, send commands from a remote machine, and spread laterally in the network.
In addition, this malware can also log keystrokes, capture screenshots, download additional payloads, and extract sensitive user information, Seqrite said, adding that such attack campaigns can effectively jeopardize the privacy and security of sensitive data at the co-operative banks and result in large scale attacks and financial frauds.
To prevent such attacks, users need to exercise ample caution and avoid opening attachments and clicking on web links in unsolicited emails.
Banks should also keep their operating systems updated and have a full-fledged security solution installed on all the devices, Seqrite advised.
