Silver Terrier Update: Increasingly Sophisticated Nigerian Cybercriminals Take Bigger Part of $3B BEC-Related Losses

Summary: Unit 42 analyzed more than 30,000 malware samples collected over three years and attributed more than 300 actors or groups to nearly half a million attacks against Palo Alto Networks customers, tracked under the name SilverTerrier since 2014. Nigerian actors used 15 separate commodity malware tools in BEC schemes, averaging 17,600 attacks per month in the past year, a 45 percent increase from 2016, against worldwide exposed losses the FBI estimates at more than US$3 billion.

What's compelling: More than 300 attributed actors running 17,600 attacks a month against businesses across every major industry vertical means BEC is not a niche problem but a sustained, industrialized campaign behind a US$3 billion loss figure.
