Cybersecurity experts at Trend Micro have recently found a new malicious campaign, through which threat actors can trap or infect its victims with its several sophisticated payloads.
This new malicious campaign is entitled as “Operation Overtrap,” and analysts have asserted that the attackers are using the three-pronged attack in this campaign. In this campaign, they are mainly targeting and stealing the banking credentials of the users from Japan.
