SafeLine is a self-hosted WAF(Web Application Firewall) to protect your web apps from attacks and exploits.
A web application firewall helps protect web apps by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web apps from attacks such as SQL injection, XSS, code injection, os command injection, CRLF injection, ldap injection, xpath injection, RCE, XXE, SSRF, path traversal, backdoor, bruteforce, http-flood, bot abused, among others.
By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine's identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.
A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application, and prevents any unauthorized data from leaving the app. It does this by adhering to a set of policies that help determine what traffic is malicious and what traffic is safe. Just as a proxy server acts as an intermediary to protect the identity of a client, a WAF operates in similar fashion but acting as an reverse proxy intermediary that protects the web app server from a potentially malicious client.

Spoofy is a program that checks if a list of domains can be spoofed based on SPF and DMARC records. You may be asking, "Why do we need another tool that can check if a domain can be spoofed?"
Well, Spoofy is different and here is why:
- Authoritative lookups on all lookups with known fallback (Cloudflare DNS)
- Accurate bulk lookups
- Custom, manually tested spoof logic (No guessing or speculating, real world test results)
- SPF lookup counter
Spoofy requires Python 3+. Python 2 is not supported. Usage is shown below:
Usage:
./spoofy.py -d [DOMAIN] -o [stdout or xls]
OR
./spoofy.py -iL [DOMAIN_LIST] -o [stdout or xls]
Install Dependencies:
pip3 install -r requirements.txt(The spoofability table lists every combination of SPF and DMARC configurations that impact deliverability to the inbox, except for DKIM modifiers.) Download Here
The creation of the spoofability table involved listing every relevant SPF and DMARC configuration, combining them, and then conducting SPF and DMARC information collection using an early version of Spoofy on a large number of US government domains. Testing if an SPF and DMARC combination was spoofable or not was done using the email security pentesting suite at emailspooftest using Microsoft 365. However, the initial testing was conducted using Protonmail and Gmail, but these services were found to utilize reverse lookup checks that affected the results, particularly for subdomain spoof testing. As a result, Microsoft 365 was used for the testing, as it offered greater control over the handling of mail.
After the initial testing using Microsoft 365, some combinations were retested using Protonmail and Gmail due to the differences in their handling of banners in emails. Protonmail and Gmail can place spoofed mail in the inbox with a banner or in spam without a banner, leading to some SPF and DMARC combinations being reported as "Mailbox Dependent" when using Spoofy. In contrast, Microsoft 365 places both conditions in spam. The testing and data collection process took several days to complete, after which a good master table was compiled and used as the basis for the Spoofy spoofability logic.

Tool was inspired by Bishop Fox's project called spoofcheck.
A pure python library for identifying the use of known or very weak cryptographic secrets across a variety of platforms. The project is designed to be both a repository of various "known secrets" (for example, ASP.NET machine keys found in examples in tutorials), and to provide a language-agnostic abstraction layer for identifying their use.
Knowing when a 'bad secret' was used is usually a matter of examining some cryptographic product in which the secret was used: for example, a cookie which is signed with a keyed hashing algorithm. Things can get complicated when you dive into the individual implementation oddities each platform provides, which this library aims to alleviate.
Check out our full blog post on the Black Lantern Security blog!
Inspired by Blacklist3r, with a desire to expand on the supported platforms and remove language and operating system dependencies.

We have a pypi package, so you can just do pip install badsecrets to make use of the library.
The absolute easiest way to use Badsecrets is by simply running badsecrets after doing a pip install:
pip install badsecrets
badsecrets eyJhbGciOiJIUzI1NiJ9.eyJJc3N1ZXIiOiJJc3N1ZXIiLCJVc2VybmFtZSI6IkJhZFNlY3JldHMiLCJleHAiOjE1OTMxMzM0ODMsImlhdCI6MTQ2NjkwMzA4M30.ovqRikAo_0kKJ0GVrAwQlezymxrLGjcEiW_s3UJMMCo
This is doing the same thing as the cli.py example shown below.
To use the examples, after doing the pip install just git clone the repo and cd into the badsecrets directory:
git clone https://github.com/blacklanternsecurity/badsecrets.git
cd badsecrets
The commands in the example section below assume you are in this directory.
If you are using the Badsecrets BBOT module, you don't need to do anything else - BBOT will install the package for you.
Bad secrets includes an example CLI for convenience when manually checking secrets. It also has a URL mode, which will connect to a target and attempt to carve for cryptographic products and check any it finds against all modules.
python ./badsecrets/examples/cli.py eyJhbGciOiJIUzI1NiJ9.eyJJc3N1ZXIiOiJJc3N1ZXIiLCJVc2VybmFtZSI6IkJhZFNlY3JldHMiLCJleHAiOjE1OTMxMzM0ODMsImlhdCI6MTQ2NjkwMzA4M30.ovqRikAo_0kKJ0GVrAwQlezymxrLGjcEiW_s3UJMMCopython ./badsecrets/examples/cli.py --url http://example.com/contains_bad_secret.htmlYou can also set a custom user-agent with --user-agent "user-agent string" or a proxy with --proxy http://127.0.0.1 in this mode.
Example output:

Microsoft today released software updates to plug 100 security holes in its Windows operating systems and other software, including a zero-day vulnerability that is already being used in active attacks. Not to be outdone, Apple has released a set of important updates addressing two zero-day vulnerabilities that are being used to attack iPhones, iPads and Macs.
On April 7, Apple issued emergency security updates to fix two weaknesses that are being actively exploited, including CVE-2023-28206, which can be exploited by apps to seize control over a device. CVE-2023-28205 can be used by a malicious or hacked website to install code.
Both vulnerabilities are addressed in iOS/iPadOS 16.4.1, iOS 15.7.5, and macOS 12.6.5 and 11.7.6. If you use Apple devices and you don’t have automatic updates enabled (they are on by default), you should probably take care of that soon as detailed instructions on how to attack CVE-2023-28206 are now public.
Microsoft’s bevy of 100 security updates released today include CVE-2023-28252, which is a weakness in Windows that Redmond says is under active attack. The vulnerability is in the Windows Common Log System File System (CLFS) driver, a core Windows component that was the source of attacks targeting a different zero-day vulnerability in February 2023.
“If it seems familiar, that’s because there was a similar 0-day patched in the same component just two months ago,” said Dustin Childs at the Trend Micro Zero Day Initiative. “To me, that implies the original fix was insufficient and attackers have found a method to bypass that fix. As in February, there is no information about how widespread these attacks may be. This type of exploit is typically paired with a code execution bug to spread malware or ransomware.”
According to the security firm Qualys, this vulnerability has been leveraged by cyber criminals to deploy Nokoyawa ransomware.
“This is a relatively new strain for which there is some open source intel to suggest that it is possibly related to Hive ransomware – one of the most notable ransomware families of 2021 and linked to breaches of over 300+ organizations in a matter of just a few months,” said Bharat Jogi, director of vulnerability and threat research at Qualys.
Jogi said while it is still unclear which exact threat actor is targeting CVE-2023-28252, targets have been observed in South and North America, regions across Asia and at organizations in the Middle East.
Satnam Narang at Tenable notes that CVE-2023-28252 is also the second CLFS zero-day disclosed to Microsoft by researchers from Mandiant and DBAPPSecurity (CVE-2022-37969), though it is unclear if both of these discoveries are related to the same attacker.
Seven of the 100 vulnerabilities Microsoft fixed today are rated “Critical,” meaning they can be used to install malicious code with no help from the user. Ninety of the flaws earned Redmond’s slightly less-dire “Important” label, which refers to weaknesses that can be used to undermine the security of the system but which may require some amount of user interaction.
Narang said Microsoft has rated nearly 90% of this month’s vulnerabilities as “Exploitation Less Likely,” while just 9.3% of flaws were rated as “Exploitation More Likely.” Kevin Breen at Immersive Labs zeroed in on several notable flaws in that 9.3%, including CVE-2023-28231, a remote code execution vulnerability in a core Windows network process (DHCP) with a CVSS score of 8.8.
“‘Exploitation more likely’ means it’s not being actively exploited but adversaries may look to try and weaponize this one,” Breen said. “Micorosft does note that successful exploitation requires an attacker to have already gained initial access to the network. This could be via social engineering, spear phishing attacks, or exploitation of other services.”
Breen also called attention to CVE-2023-28220 and CVE-2023-28219 — a pair of remote code execution vulnerabilities affecting Windows Remote Access Servers (RAS) that also earned Microsoft’s “exploitation more likely” label.
“An attacker can exploit this vulnerability by sending a specially crafted connection request to a RAS server, which could lead to remote code execution,” Breen said. While not standard in all organizations, RAS servers typically have direct access from the Internet where most users and services are connected. This makes it extremely enticing for attackers as they don’t need to socially engineer their way into an organization. They can simply scan the internet for RAS servers and automate the exploitation of vulnerable devices.”
