Active for over half a decade, Emotet has evolved from a banking Trojan to information stealer and malware downloader, and has been rather quiet for the past year or so.
In September 2019, following a four-month vacation, Emotet recommenced activity with a new technique in its pocket: it was hijacking legitimate email conversations for successful spear-phishing.
The threat became quiet again at the beginning of this year, but last week security researchers observed the first malspam waves aimed at distributing the Trojan.
