Trustwave SpiderLabs in early April observed a Grandoreiro malware campaign targeting bank users from Brazil, Spain, and Mexico. The campaign exploits the tax season in target countries by sending out tax-themed phishing emails.
The Trustwave SpiderLabs Email Security team identified a phishing campaign pretending to be a missed package from DHL. What’s interesting about this campaign is that clicking on the link leads to a chatbot that discusses the missed package, provides pictures of it, and guides the potential victim through providing their credit card information and user credentials.
So, what is PwnFox? To put it simply, it’s a BurpPro extension that works with Firefox. It accomplishes two things. First, it helps containerize up to eight (yes, that’s right… eight!) different sessions within one browser and secondly, it organizes all your proxied traffic in Burp BY COLOR!

Appending a malicious file to an unsuspecting file format is one of the tricks our adversaries use to evade detection. Recently, we came across an interesting email campaign employing this technique to deliver the info stealer Vidar malware.
Lapsus$ is the breakout cybercriminal gang making government entities and organizations in manufacturing, higher education, energy, retailers, and healthcare around the world question whether they could be the victim of a cyberattack.
In today’s environment, much of the population are doing their bank or financial transactions online and online banking or wire transfers have become a huge necessity. Recently, we received a phishing email that is targeting PayPal accounts.
Recently, we encountered an interesting phishing webpage that caught our interest because it acts like a chameleon by changing and blending its color based on its environment. In addition, the site adapts its background page and logo depending on user input to trick its victims into giving away their email credentials.
This guide will, hopefully, let you skip the headaches and guesswork that we endured learning this process when you try to get a CVE published.
When a company implements multifactor authentication, the organization is usually confident that it’s using the best system possible. However, not all MFA is built the same and there are times when the MFA solution being implemented is not delivering the protection required.

During a recent engagement, Trustwave SpiderLabs discovered a vulnerability (CVE-2021-45901) within ServiceNow (Orlando) which allows for a successful username enumeration by using a wordlist. By using an unauthenticated session and navigating to the password reset form, it is possible to infer a valid username. This is achieved through examination of the HTTP POST response data initially triggered by the password reset web form. This response differs depending on a username's existence.
During an investigation of a malware campaign, I discovered that multiple emails were bypassing a specific email security system. Interestingly, there were no bypass techniques used. Instead, the flood of spear-phishing emails made the email security system allow some of the emails, at which point I began my research on Microsoft Outlook.
Trustwave security and engineering teams became aware of the vulnerability in Polkit's pkexec component identified as CVE-2021-4034 (PwnKit) on January 25. We immediately investigated the vulnerability and potential exploits and continue to actively monitor the situation for our clients.
