Emotet, one of the most prolific and disruptive botnet malware-delivery systems, appears to be making a comeback after nearly a year of inactivity, researchers have found.
"TrickBot launched what appears to be the newer Emotet loader."
Because Emotet was largely dismantled earlier this year by an international law-enforcement effort, researchers said they were "Suspicious about the findings" and conducted further verification of the activity.
Emotet appeared to be put out of commission by an international law-enforcement collaborative takedown of a network of hundreds of botnet servers supporting the system in January 2021.
Often, it was Emotet using its vast network to deliver TrickBot as a payload in targeted email phishing campaigns, though TrickBot also in the past has delivered Emotet samples - which appears to be the case once more.
Researchers detailed the similarities between previous samples of Emotet and the one they observed being dropped by TrickBot on Sunday.
