Finding assets from certificates! Scan the web! Tool presented @DEFCON 31
** You must have CGO enabled, and may have to install gcc to run CloudRecon**
FreshRSS sudo apt install gccgo install github.com/g0ldencybersec/CloudRecon@latestCloudRecon
CloudRecon is a suite of tools for red teamers and bug hunters to find ephemeral and development assets in their campaigns and hunts.
Often, target organizations stand up cloud infrastructure that is not tied to their ASN or related to known infrastructure. Many times these assets are development sites, IT product portals, etc. Sometimes they don't have domains at all but many still need HTTPs.
CloudRecon is a suite of tools to scan IP addresses or CIDRs (ex: cloud providers IPs) and find these hidden gems for testers, by inspecting those SSL certificates.
The tool suite is three parts in GO:
Scrape - A LIVE running tool to inspect the ranges for a keywork in SSL certs CN and SN fields in real time.
Store - a tool to retrieve IPs certs and download all their Orgs, CNs, and SANs. So you can have your OWN cert.sh database.
Retr - a tool to parse and search through the downloaded certs for keywords.

Zero-dollar attack surface management tool
featured at Black Hat Arsenal 2023 and Recon Village @ DEF CON 2023.
Easy EASM is just that... the easiest to set-up tool to give your organization visibility into its external facing assets.
The industry is dominated by $30k vendors selling "Attack Surface Management," but OG bug bounty hunters and red teamers know the truth. External ASM was born out of the bug bounty scene. Most of these $30k vendors use this open-source tooling on the backend.
With ten lines of setup or less, using open-source tools, and one button deployment, Easy EASM will give your organization a complete view of your online assets. Easy EASM scans you daily and alerts you via Slack or Discord on newly found assets! Easy EASM also spits out an Excel skeleton for a Risk Register or Asset Database! This isn't rocket science, but it's USEFUL. Don't get scammed. Grab Easy EASM and feel confident you know what's facing attackers on the internet.
go install github.com/g0ldencybersec/EasyEASM/easyeasm@latestThe tool expects a configuration file named config.yml to be in the directory you are running from.
Here is example of this yaml file:
# EasyEASM configurations
runConfig:
domains: # List root domains here.
- example.com
- mydomain.com
slack: https://hooks.slack.com/services/DUMMYDATA/DUMMYDATA/RANDOM # Slack webhook url for Slack notifications.
discord: https://discord.com/api/webhooks/DUMMYURL/Dasdfsdf # Discord webhook for Discord notifications.
runType: fast # Set to either fast (passive enum) or complete (active enumeration).
activeWordList: subdomainWordlist.txt
activeThreads: 100To run the tool, fill out the config file: config.yml. Then, run the easyeasm module:
./easyeasmAfter the run is complete, you should see the output CSV (EasyEASM.csv) in the run directory. This CSV can be added to your asset database and risk register!

KrebsOnSecurity received a nice bump in traffic this week thanks to tweets from the Federal Bureau of Investigation (FBI) and the Federal Communications Commission (FCC) about “juice jacking,” a term first coined here in 2011 to describe a potential threat of data theft when one plugs their mobile device into a public charging kiosk. It remains unclear what may have prompted the alerts, but the good news is that there are some fairly basic things you can do to avoid having to worry about juice jacking.
On April 6, 2023, the FBI’s Denver office issued a warning about juice jacking in a tweet.
“Avoid using free charging stations in airports, hotels or shopping centers,” the FBI’s Denver office warned. “Bad actors have figured out ways to use public USB ports to introduce malware and monitoring software onto devices. Carry your own charger and USB cord and use an electrical outlet instead.”
Five days later, the Federal Communications Commission (FCC) issued a similar warning. “Think twice before using public charging stations,” the FCC tweeted. “Hackers could be waiting to gain access to your personal information by installing malware and monitoring software to your devices. This scam is referred to as juice jacking.”
The FCC tweet also provided a link to the agency’s awareness page on juice jacking, which was originally published in advance of the Thanksgiving Holiday in 2019 but was updated in 2021 and then again shortly after the FBI’s tweet was picked up by the news media. The alerts were so broadly and breathlessly covered in the press that a mention of juice jacking even made it into this week’s Late Late Show with James Corden.
The term juice jacking crept into the collective paranoia of gadget geeks in the summer of 2011, thanks to the headline for a story here about researchers at the DEFCON hacker convention in Vegas who’d set up a mobile charging station designed to educate the unwary to the reality that many mobile devices connected to a computer would sync their data by default.
Since then, Apple, Google and other mobile device makers have changed the way their hardware and software works so that their devices no longer automatically sync data when one plugs them into a computer with a USB charging cable. Instead, users are presented with a prompt asking if they wish to trust a connected computer before any data transfer can take place.
On the other hand, the technology needed to conduct a sneaky juice jacking attack has become far more miniaturized, accessible and cheap. And there are now several products anyone can buy that are custom-built to enable juice jacking attacks.
Probably the best known example is the OMG cable, a $180 hacking device made for professional penetration testers that looks more or less like an Apple or generic USB charging cable. But inside the OMG cable is a tiny memory chip and a Wi-Fi transmitter that creates a Wi-Fi hotspot, to which the attacker can remotely connect using a smartphone app and run commands on the device.

Brian Markus is co-founder of Aries Security, and one of the researchers who originally showcased the threat from juice jacking at the 2011 DEFCON. Markus said he isn’t aware of any public accounts of juice jacking kiosks being found in the wild, and said he’s unsure what prompted the recent FBI alert.
But Markus said juice jacking is still a risk because it is far easier and cheaper these days for would-be attackers to source and build the necessary equipment.
“Since then, the technology and components have become much smaller and very easy to build, which puts this in the hands of less sophisticated threat actors,” Markus said. “Also, you can now buy all this stuff over the counter. I think the risk is possibly higher now than it was a decade ago, because a much larger population of people can now pull this off easily.”
How seriously should we take the recent FBI warning? An investigation by the myth-busting site Snopes suggests the FBI tweet was just a public service announcement based on a dated advisory. Snopes reached out to both the FBI and the FCC to request data about how widespread the threat of juice jacking is in 2023.
“The FBI replied that its tweet was a ‘standard PSA-type post’ that stemmed from the FCC warning,” Snopes reported. “An FCC spokesperson told Snopes that the commission wanted to make sure that their advisory on “juice-jacking,” first issued in 2019 and later updated in 2021, was up-to-date so as to ensure ‘the consumers have the most up-to-date information.’ The official, who requested anonymity, added that they had not seen any rise in instances of consumer complaints about juice-jacking.”
What can you do to avoid juice jacking? Bring your own gear. A general rule of thumb in security is that if an adversary has physical access to your device, you can no longer trust the security or integrity of that device. This also goes for things that plug into your devices.
Juice jacking isn’t possible if a device is charged via a trusted AC adapter, battery backup device, or through a USB cable with only power wires and no data wires present. If you lack these things in a bind and still need to use a public charging kiosk or random computer, at least power your device off before plugging it in.
