LinkedIn Phishing Email Enumeration

Using an automated web bot, it is possible to scrape personnel names and then translate those names into emails that can be used in phishing campaigns. Proof of concept uploaded to Github.

Creating the LinkedIn Web Bot

While testing, it was identified that LinkedIn will temporarily disable accounts suspected of employing bot automation (and presumably with enough violations, could result in permanent deletion of account).

The team found that by rate-limiting requests at varied intervals and limiting total daily requests to less that 800, we were able to use automated bots on the network without having the accounts suspended.

Bot Operations

The proof of concept bot does the following:

Logs into LinkedIn using an existing account
Searches the supplied company name
Narrows the search to return "People" objects
Opens Advanced Search options, and selects only individuals that currently work at the company
Progressively clicks through 100 pages of profiles and gathers names
Converts the names into emails based on a known-naming convention

Bypassing CAPTCHA with Visually-Impaired Robots

As many of you have probably noticed, we rely heavily on bot automation for a lot of the testing that we do at Sociosploit. And occasionally, we run into sites that leverage CAPTCHA ("Completely Automated Public Turing Test To Tell Computers and Humans Apart") controls to prevent bot automation. Even if you aren't familiar with the name, you've likely encountered these before. While there are some other vendors who develop CAPTCHAs, Google is currently the leader in CAPTCHA technology. They currently support 2 products (reCAPTCHA v2 and v3). As v3 natively only functions as a detective control, I focused my efforts more on identifying ways to possibly bypass reCAPTCHA v2 (which functions more as a preventative control). How reCAPTCHA v2 Works reCAPTCHA v2 starts with a simple checkbox, and evaluates the behavior of the user when clicking it. While I haven't dissected the underlying operations, I assume this part of the test likely makes determ...

Another "Fappening" on the Horizon?

So in case you aren't fully up-to-speed on useless hacker trivia, "The Fappening" (also sometimes referred to as "Celebgate") was a series of targeted end-user cyber attacks which occurred back in 2014 (which strangely feels like forever in tech years), that resulted in unauthorized access to the iCloud accounts of several prominent celebrity figures. Following these breaches, photographs (for many including personal sexually explicit or nude photos) of the celebrities were then publicly released online. Most evidence points to the attack vector being spear phishing email attacks which directed the victims to a fake icloud login site, and then collected the victim's credentials to subsequently access their real icloud accounts. Migration to MFA In response to these events, Apple has made iCloud one of the very few social web services that implements compulsory MFA ("Multi-Factor Authentication"). But while they might be ahead of the indust...

That Escalated Quickly -- Chihuahua, Muffins, and the Impending Privacy Crisis!!!

So this is a story of how I recently went from exploring the seemingly harmless new capabilities of GPT-4, to discovering one of its darkest and most concerning secrets. It turns out, that GPT-4 has the ability to tell you exactly who that random person is that you have a crush on at the gym. Somebody cut you off in traffic and you want to exact revenge? There is a good chance that GPT-4 can tell you who they are. In fact, GPT-4 is apparently capable of recognizing people broadly (thanks to it's consumption and subsequent analysis of all of the photos across the Internet). But let's rewind and I'll explain how we got here. Muffin vs Chihuahua So OpenAI recently released the new image analysis features of its multi-modal version of GPT-4 (for premium paying customers). Shortly after this release, I saw somebody put these capabilities to the ultimate test, by having GPT-4 play the classic machine learning Computer Vision (CV) challenge of Chihuahua vs Muffin . The results we...
