∗∗∗ Phishing links with @ sign and the need for effective security awareness building, (Mon, Sep 23rd) ∗∗∗
---------------------------------------------
While going over a batch of phishing e-mails that were delivered to us here at the Internet Storm Center during the first half of September, I noticed one message which was somewhat unusual. Not because it was untypically sophisticated or because it used some completely new technique, but rather because its authors took advantage of one of the less commonly misused aspects of the URI format – the ability to specify information about a user in the URI before its "host" part (domain or IP address).

∗∗∗ Why Do Criminals Love Phishing-as-a-Service Platforms? ∗∗∗
---------------------------------------------
Phishing-as-a-Service (PaaS) platforms have become the go-to tool for cybercriminals, to launch sophisticated phishing campaigns targeting the general public and businesses, especially in the financial services sector. [..] In this blog, we’ll explore the key features offered by PaaS platforms, highlight the major platforms Trustwave SpiderLabs has recently observed, and cover effective phishing mitigation strategies.

∗∗∗ CISA boss: Makers of insecure software are enablers of the real villains ∗∗∗
---------------------------------------------
Software suppliers who ship buggy, insecure code are the true baddies in the cyber crime story, Jen Easterly, boss of the US government's Cybersecurity and Infrastructure Security Agency, has argued. "The truth is: Technology vendors are the characters who are building problems" into their products, which then "open the doors for villains to attack their victims," declared Easterly during a Wednesday keynote address at Mandiant's mWise conference.

∗∗∗ Proxy Detection: Comparing Detection Services with the Truth ∗∗∗
---------------------------------------------
In our previous blog post, we looked at different (free and paid) solutions to detect the use of anonymity tools during attacks executed on our Remote Desktop Protocol (RDP) honeypots. Confronted with inconclusive outcomes, this blog post aims to evaluate the different proxy detector tools by analyzing their results with our dataset of Truth.
