It then uses common malware delivery techniques such as spear phishing and Strategic Web Compromises (SWC).

This practice has been observed during a malspam campgin, where emails disguised as payment transfer confirmation deliver an xls file containing infostealer Lokibot. [19 IOCs] Learn more >

Trickbot delivered via Redirection URL in spam
A Trickbot variant uses Google to redirect from an URL to sidestep spam filters that initially block the Trojan. At first glance, the spam email could pass as legitimate, even adding social media icons for authenticity. The content details a package order along with seller contact information and other convincing information. [12 IOCs] Learn more >
