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 industry in…

Ready, Set, Secure

Got the privilege to be a guest on the recent Set Solutions Information Security podcast -- Ready, Set, Secure.  Talking with Michael Farnum (Chief Technology Officer), Nick DiPasquale (Senior Security Solutions Architect), and John Dearman (Senior Penetration Testing Consultant) about recent news and discuss new trends in hacking and penetration testing.

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 WorksreCAPTCHA 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 determinations about t…

Sociosploit at HouSecCon

Recently had the privilege to present some of our latest projects at HouSecCon.  Within the presentation, I cover the following:

OkStupid and Plenty of Phish

It recently occurred to me that many of the classic "password recovery" questions, while personal in nature, are exactly the types of questions you would ask when attempting to better get to know someone -- such as in a dating context.  With this in mind, I decided to explore how online dating services could potentially be used to target victims and then subsequently get access to their online services by discovering the answer(s) to their password recovery questions.

How we built the bot Went through quite a few considerations on how I wanted to approach this.  I eventually stumbled upon a site called PersonalityForge, which seems to be this entire geek sub-culture of people who have coded chat bots with the intent to make them as real as possible.  While nowhere near perfect, I did manage to find a "flirty" female chat bot that I hoped would do the trick.  I introduce to you, Amanda20...

How it works? Using the Python mechanize library, I was able to use browsing e…

Twitter Remote Access Trojan (Twittersploit)

Developed a malware sample that leverages Twitter direct messaging as a channel for command and control.
Web Service Command and Control Have recently been structuring a lot of my penetration testing efforts around the MITRE ATT&CK framework. One technique that specifically caught my attention while doing an assessment based on the Command & Control (C&C) section was the T1102 - Web Service C&C technique. It references multiple malware samples that leveraged Twitter as a C&C channel. These samples included: CozyCarHAMMERTOSSMiniDukeOnionDuke This technique proved to be uniquely effective for a few reasons: Traditional C&C Channels Blocked - Many organizations are now taking a (quasi) white-listing approach to URL filtering (i.e. blocking unclassified site categories), thereby blocking hastily established C&C channels over HTTP(S)Web Service Availability - More and more organizations are opening up corporate infrastructure to social media web services (such as…

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 accountSearches the supplied company nameNarrows the search to return "People" objectsOpens Advanced Search options, and selects only individuals that currently work at the companyProgressively clicks through 100 pages of profiles and gathers namesConverts the …
