Memcrashed is a Memcached DDoS exploit tool written in Python that allows you to send forged UDP packets to a list of Memcached servers obtained from Shodan.
This is related to the recent record-breaking Memcached DDoS attacks that are likely to plague 2018 with over 100,000 vulnerable Memcached servers showing up in Shodan.
What is Memcached?
Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
QualysGuard is a web-based vulnerability management tool provided by Qualys, Inc, which was the first company to deliver vulnerability management services as a SaaS-based web-service.
From reviews, it seems like a competent tool with a low rate of false positives that is fairly easy to work with and keep the more ‘dangerous’ parts of vulnerability scanning out of the hands of users, but with the flexibility for expert users to do what they need.
So after the massive DDoS attack trend in 2016 it seems like 2018 is going to the year of the Memcached DDoS amplification attack with so many insecure Memcached servers available on the public Internet.
Unfortunately, it looks like a problem that won’t easily go away as there are so many publically exposed, poorly configured Memcached servers online (estimated to be over 100,000).
Honestly, Github handled the 1.3Tbps attack like a champ with only 10 minutes downtime although they did deflect it by moving traffic to Akamai.
Sodium is a new, easy-to-use software library for encryption, decryption, signatures, password hashing and more. It is a portable, cross-compilable, installable, packageable fork of NaCl, with a compatible API, and an extended API to improve usability even further.
XSStrike is an advanced XSS detection suite, which contains a powerful XSS fuzzer and provides zero false positive results using fuzzy matching. XSStrike is the first XSS scanner to generate its own payloads.
It is also built in an intelligent enough manner to detect and break out of various contexts.
Features of XSStrike XSS Fuzzer & Hacking Tool
- Powerful fuzzing engine
- Context breaking technology
- Intelligent payload generation
- GET & POST method support
- Cookie Support
- WAF Fingerprinting
- Handcrafted payloads for filter and WAF evasion
- Hidden parameter discovery
- Accurate results via levenshtein distance algorithm

The latest ransomware kicking everyone’s ass is Gandcrab which has infected an estimated 50,000 computers, fortunately for the victims, Bitdefender has released a free Gandcrab ransomware decryption tool as a part of the No More Ransom Project.
There’s nothing particularly notable about the ransomware itself other than it combines two existing exploit kits to compromise people and it takes payment in Dash, which is a privacy coin, rather than Bitcoin (which is a first as far as I know).
Quickjack is an intuitive, point-and-click tool for performing advanced and covert clickjacking and frame slicing attacks. It also allows you to easily perform clickjacking, or steal “clicks” from users on many websites, forcing the user to unknowingly click buttons or links (for example the Facebook Like button) using their own cookies.
Quickjack By placing the auto-generated code on any site, you can obtain thousands of clicks quickly from different users, or perform targeted attacks by luring a victim to a specific URL.
BootStomp is a Python-based tool, with Docker support that helps you find two different classes of Android bootloader vulnerabilities and bugs. It looks for memory corruption and state storage vulnerabilities.
Note that BootStomp works with boot-loaders compiled for ARM architectures (32 and 64 bits both) and that results might slightly vary depending on angr and Z3’s versions. This is because of the time angr takes to analyze basic blocks and to Z3’s expression concretization results.
Google is ramping up its campaign against HTTP only sites and is going to mark ALL Non-HTTPS sites insecure in July 2018 with the release of Chrome 68. It’s a pretty strong move, but Google and the Internet, in general, has been moving in this direction for a while.
It started with suggestions, then forced SSL on all sites behind logins, then mixed-content warnings, then showing HTTP sites are not-secured and now it’s going to be outright marked as insecure.
Altdns is a Subdomain Recon Tool in Python that allows for the discovery of subdomains that conform to patterns. The tool takes in words that could be present in subdomains under a domain (such as test, dev, staging) as well as takes in a list of subdomains that you know of.
From these two lists that are provided as input to altdns, the tool then generates a massive output of “altered” or “mutated” potential subdomains that could be present.
