Researchers at SpyCloud have observed a 400% year-over-year increase in successful phishing attacks, with a disproportionate number of attacks targeting corporate accounts. “The company tracked a 400% year-over-year increase in successfully phished identities, with nearly 40% of the 28+ million recaptured phished records containing a business email address – compared to just 11.5% in recaptured malware data,” the researchers write.

Researchers at CyberProof warn that threat actors are launching phishing attacks via Microsoft Teams' “Chat with Anyone” feature, which lets external users send direct messages via email addresses. “Microsoft Teams now allows users to send direct chat invitations to any email address, even if recipients aren’t part of a Teams tenant,” the researchers explain.

Threat actors are using the open-source phishing framework Evilginx to target universities across the United States, according to researchers at Infoblox. The attackers have targeted at least 18 universities and educational entities since April 2025, using phishing pages that spoofed student single sign-on (SSO) portals. “In the campaigns we analyzed, students were targeted via personalized emails that contained TinyURL links,” Infoblox says.

ReliaQuest warns that the cybercriminal collective “Scattered Lapsus$ Hunters” appears to be using social engineering attacks to target organizations’ Zendesk instances.

Researchers at Palo Alto Networks’ Unit 42 are tracking two new malicious AI tools, WormGPT 4 and KawaiiGPT, that allow threat actors to craft phishing lures and generate ransomware code.

The latest version of WormGPT offers lifetime access for $220, or a monthly fee of $50.

Sophisticated online fraud techniques are growing more accessible to unskilled attackers, driven by AI tools and fraud-as-a-service platforms, according to Sumsub’s latest Identity Fraud Report. “hile the volume of attacks remains staggering, the nature of fraud is shifting,” the researchers write.
