Cybersecurity researchers are alerting of phishing campaigns that abuse  Cloudflare Workers  to serve phishing sites that are used to harvest users' credentials associated with Microsoft, Gmail, Yahoo!, and cPanel Webmail. The attack method, called transparent phishing or adversary-in-the-middle ( AitM ) phishing, "uses Cloudflare Workers to act as a reverse proxy server for a legitimate login page, intercepting traffic between the victim and the login page to capture credentials, cookies, and tokens," Netskope researcher Jan Michael Alcantara  said  in a report. A majority of phishing campaigns hosted on Cloudflare Workers over the past 30 days have targeted victims in Asia, North America, and Southern Europe, spanning technology, financial services, and banking sectors. The cybersecurity firm said that an increase in traffic to Cloudflare Workers-hosted phishing pages was first registered in Q2 2023, noting it observed a spike in the total number of d...

In today's digital landscape, traditional password-only authentication systems have proven to be vulnerable to a wide range of cyberattacks. To safeguard critical business resources, organizations are increasingly turning to multi-factor authentication (MFA) as a more robust security measure. MFA requires users to provide multiple authentication factors to verify their identity, providing an additional layer of protection against unauthorized access. However, cybercriminals are relentless in their pursuit of finding ways to  bypass MFA systems . One such method gaining traction is MFA spamming attacks, also known as MFA fatigue, or  MFA bombing . This article delves into MFA spamming attacks, including the best practices to mitigate this growing threat. What is MFA spamming? MFA spamming refers to the malicious act of inundating a target user's email, phone, or other registered devices with numerous MFA prompts or confirmation codes. The objective behind this tactic is to ...

A new research has uncovered multiple vulnerabilities that could be exploited to bypass  Windows Hello authentication  on Dell Inspiron 15, Lenovo ThinkPad T14, and Microsoft Surface Pro X laptops. The flaws were discovered by researchers at hardware and software product security and offensive research firm Blackwing Intelligence, who found the weaknesses in the fingerprint sensors from Goodix, Synaptics, and ELAN that are embedded into the devices. A prerequisite for the fingerprint reader exploits is that the users of the targeted laptops have fingerprint authentication already set up. All the three fingerprint sensors are a type of sensor called "match on chip" ( MoC ), which integrates the matching and other biometric management functions directly into the sensor's integrated circuit. "While MoC prevents replaying stored fingerprint data to the host for matching, it does not, in itself, prevent a malicious sensor from spoofing a legitimate sensor's commu...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...
