The Silent Librarian threat group is constantly updating its tactics and techniques, researchers say. Its phishing campaigns are more frequent from June through October and primary targets are universities in North America, many of them in the United States, and Europe. Its purpose is to steal intellectual property from universities across the globe. A facade of legitimacy is maintained by keeping track of the changes in authentication portals almost in real time, and integrating them into the phishing pages. The methods used by this threat actor are far from sophisticated, but the continuation of these campaigns proves that they are efficient.
