A phishing email purportedly from LinkedIn with the subject line "We noticed some unusual activity" was discovered targeting users at a travel organization, in an attempt to pilfer their credentials on the social-media platform.
The phishing campaign slipped past Google's email security controls after cheating email authentication checks via SFP and DMARC, according to Armorblox, whose email security system at the victim organization found and stopped the attack pointed at some 500 user inboxes.
