Largescale Phishing Campaign Targets Zimbra Collaboration Email Servers
Researchers at ESET have identified a largescale and ongoing phishing campaign targeting Zimbra Collaboration email servers at small- and medium-sized businesses and government agencies. The campaign has been active since at least April and is being conducted globally, with Poland, Ecuador, and Italy the most targeted countries. The campaign does not appear to be targeted on any specific vertical. Targets are sent an email with an HTML attachment. The email warns the user about an email server update or another Zimbra issue, such as a security update. The From field indicates the email has been sent by an email server administrator. The user is told that they need to download the HTML attachment, which will have a URL pointing to a local file patch. The HTML attachment includes the targeted organization’s logo, the organization’s name, and a fake login page, with the username prefilled. The user is only required to enter their password. If the password is entered, the credentials are transmitted by HTTPS POST request to an adversary-controlled server. The ESET researchers observed...

Mandiant: Malicious Actors Use of Generative AI Remains Limited
There is justifiable fear that malicious actors will leverage generative AI to facilitate their malicious activities; however, the adoption of generative AI by threat actors appears to be limited, certainly for intrusion operations. Mandiant reports that it has been tracking threat actor interest in generative AI, but its research and open source accounts indicate generative AI is only currently being used to a significant extent for social engineering and misinformation campaigns. Mandiant has found evidence indicating generative AI is being used to create convincing lures for phishing and business email compromise (BEC) attacks. Malicious actors can create text output reflecting natural human speech patterns for phishing lures and enhance the complexity of language in their existing operations. Threat actors have used generative AI to manipulate video and voice content in BEC scams and to manipulate images to defeat know-your-customer (KYC) requirements. Evidence has also been obtained indicating financially motivated threat actors are using the malicious WormGPT tool to create...
