Today My Online Security published research describing a fairly large Ursnif campaign targeting the United Kingdom. The threat actors behind the attack are using Brexit as a topical lure to attract potential phishing candidates, with emails mentioning Brexit in the subject line linking to a google document that downloads the malware file.
On Twitter a user by the name of craT0x (@justmlwhunting) published the payload of this malware sample. We took the payload from the researcher’s tweet and performed an analysis on our Genetic Malware Analysis tool, Intezer Analyze, to see if we could confirm that the payload shares code with previously seen Ursnif samples.
Thank you for sharing!
