Security researchers tested 50 well-known jailbreaks against DeepSeek’s popular new AI chatbot. It didn’t stop a single one.
Ever since OpenAI released ChatGPT at the end of 2022, hackers and security researchers have tried to find holes in large language models (LLMs) to get around their guardrails and trick them into spewing out hate speech, bomb-making instructions, propaganda, and other harmful content. In response, OpenAI and other generative AI developers have refined their system defenses to make it more difficult to carry out these attacks. But as the Chinese AI platform DeepSeek rockets to prominence with its new, cheaper R1 reasoning model, its safety protections appear to be far behind those of its established competitors.
Today, security researchers from Cisco and the University of Pennsylvania are publishing findings showing that, when tested with 50 malicious prompts designed to elicit toxic content, DeepSeek’s model did not detect or block a single one. In other words, the researchers say they were shocked to achieve a “100 percent attack success rate.”
The findings are part of a growing body of evidence that DeepSeek’s safety and security measures may not match those of other tech companies developing LLMs. DeepSeek’s censorship of subjects deemed sensitive by China’s government has also been easily bypassed.
“A hundred percent of the attacks succeeded, which tells you that there’s a trade-off,” DJ Sampath, the VP of product, AI software and platform at Cisco, tells WIRED. “Yes, it might have been cheaper to build something here, but the investment has perhaps not gone into thinking through what types of safety and security things you need to put inside of the model.”
Other researchers have had similar findings. Separate analysis published today by the AI security company Adversa AI and shared with WIRED also suggests that DeepSeek is vulnerable to a wide range of jailbreaking tactics, from simple language tricks to complex AI-generated prompts.
DeepSeek, which has been dealing with an avalanche of attention this week and has not spoken publicly about a range of questions, did not respond to WIRED’s request for comment about its model’s safety setup.
Generative AI models, like any technological system, can contain a host of weaknesses or vulnerabilities that, if exploited or set up poorly, can allow malicious actors to conduct attacks against them. For the current wave of AI systems, indirect prompt injection attacks are considered one of the biggest security flaws. These attacks involve an AI system taking in data from an outside source—perhaps hidden instructions of a website the LLM summarizes—and taking actions based on the information.
Jailbreaks, which are one kind of prompt-injection attack, allow people to get around the safety systems put in place to restrict what an LLM can generate. Tech companies don’t want people creating guides to making explosives or using their AI to create reams of disinformation, for example.
Jailbreaks started out simple, with people essentially crafting clever sentences to tell an LLM to ignore content filters—the most popular of which was called “Do Anything Now” or DAN for short. However, as AI companies have put in place more robust protections, some jailbreaks have become more sophisticated, often being generated using AI or using special and obfuscated characters. While all LLMs are susceptible to jailbreaks, and much of the information could be found through simple online searches, chatbots can still be used maliciously.
“Jailbreaks persist simply because eliminating them entirely is nearly impossible—just like buffer overflow vulnerabilities in software (which have existed for over 40 years) or SQL injection flaws in web applications (which have plagued security teams for more than two decades),” Alex Polyakov, the CEO of security firm Adversa AI, told WIRED in an email.
Cisco’s Sampath argues that as companies use more types of AI in their applications, the risks are amplified. “It starts to become a big deal when you start putting these models into important complex systems and those jailbreaks suddenly result in downstream things that increases liability, increases business risk, increases all kinds of issues for enterprises,” Sampath says.
The Cisco researchers drew their 50 randomly selected prompts to test DeepSeek’s R1 from a well-known library of standardized evaluation prompts known as HarmBench. They tested prompts from six HarmBench categories, including general harm, cybercrime, misinformation, and illegal activities. They probed the model running locally on machines rather than through DeepSeek’s website or app, which send data to China.
Beyond this, the researchers say they have also seen some potentially concerning results from testing R1 with more involved, non-linguistic attacks using things like Cyrillic characters and tailored scripts to attempt to achieve code execution. But for their initial tests, Sampath says, his team wanted to focus on findings that stemmed from a generally recognized benchmark.
Cisco also included comparisons of R1’s performance against HarmBench prompts with the performance of other models. And some, like Meta’s Llama 3.1, faltered almost as severely as DeepSeek’s R1. But Sampath emphasizes that DeepSeek’s R1 is a specific reasoning model, which takes longer to generate answers but pulls upon more complex processes to try to produce better results. Therefore, Sampath argues, the best comparison is with OpenAI’s o1 reasoning model, which fared the best of all models tested. (Meta did not immediately respond to a request for comment).
Polyakov, from Adversa AI, explains that DeepSeek appears to detect and reject some well-known jailbreak attacks, saying that “it seems that these responses are often just copied from OpenAI’s dataset.” However, Polyakov says that in his company’s tests of four different types of jailbreaks—from linguistic ones to code-based tricks—DeepSeek’s restrictions could easily be bypassed.
“Every single method worked flawlessly,” Polyakov says. “What’s even more alarming is that these aren’t novel ‘zero-day’ jailbreaks—many have been publicly known for years,” he says, claiming he saw the model go into more depth with some instructions around psychedelics than he had seen any other model create.
“DeepSeek is just another example of how every model can be broken—it’s just a matter of how much effort you put in. Some attacks might get patched, but the attack surface is infinite,” Polyakov adds. “If you’re not continuously red-teaming your AI, you’re already compromised.”
I would normally write today about Patch Tuesday. And indeed, Microsoft applied updated to 79 vulnerabilities yesterday across Windows, Microsoft Office, Azure services and other core components. A breakdown can be read here. I want to point out that I didn’t get that link from my cyber news feed, but had to hunt for it a little. Instead, my feed is chock full of incursions by a ClickFix campaign against WordPress (again), exploited vulnerabilities being added by CISA to the KEV catalog and a case of AI autonomously using SQL injection to answer simple queries.
That last one is interesting, and gives some insight into how AI tools process commands. As well as how unpatched vulnerabilities can lead to external exploitation. Truffle Security, who published the report, notes that no real companies were in danger during their study. The testing was done on purpose-made clones of major websites in a sandboxed environment. They tested Claude Opus, Claude Sonnet and over 30 other models once the research led them to this discovery. A proper experiment requires repeatability, after all.
The initial query was simple: find a blog post on a specific topic. Claude’s capability was limited to a web_fetch request that should have returned a single result, although the system prompt was to be thorough and persistent, exhausting all options before concluding a task could not be completed. The test was also simple. The legitimate path from query to result was broken. The test environment contained real, exploitable vulnerabilities of the kind found routinely in production systems, according to the report, that cause internal server errors or other crashes. What would the AI do? Evidently, it decided to hack its way in to complete its command. And Claude wasn’t the only one. The article breaks down in detail how each AI agent responded to the test, some with greater degree of exploitation of the vulnerabilities than others, the majority in fact. Those that did all used the same tactic.
A Structured Query Language (SQL) injection is, in essence, the rewording of an executable command in order to make it run when it would not otherwise. These days we see it often in prompt injection malware that leads to compromise in devices without the user aware of it. But it has always been an exploitable function of code. By giving an underlying command of persistence in the agents, permission to use SQL injection to complete their tasks is tacitly given.
This study is a good example of how agentic AI uses its ability to interpret commands in a way that might not be intended. A human tasked with this would probably not choose to use a function that is illegal, but what is legality to a machine? It hasn’t been told not to use a particular tactic, so it does not exclude it from its available options. I’ve talked before about how coding language is written in a way that every line of it is a yes/no variable. If/then. Without limitations written into the parameters of the root command – in other words the system prompt – an LLM will continue to find or create pathways until it meets its given task or determines that it cannot. Best case, it returns without result in the event of failure to complete. The rest of the time it makes something up, using aggregated data from related search queries in order to present something plausible (again, because it likely hasn’t been told not to do that).
This was conducted in a test environment and is not a real world scenario, but it illuminates why specificity matters so much. LLM’s are literal. They have no concept of nuance, judgment or even privacy, since they are just machine tools going from point A to point B. It’s also how such incursions are made possible by threat actors using these tools to formulate their attacks. And on this informally designated Exploit Wednesday, it’s why patching vulnerabilities should be a priority.
Mastering SQL Injection (SQLi) Protection for Symfony with Examples
Understanding and Preventing SQL Injection (SQLi) in Symfony Applications
SQL Injection (SQLi) remains one of the most common and damaging vulnerabilities affecting web applications. This guide will dive into what SQLi is, why Symfony developers should be aware of it, and practical, example-based strategies to prevent it in Symfony applications.
What is SQL Injection (SQLi)?
SQL Injection occurs when attackers can insert malicious SQL code into a query, allowing them to access, alter, or delete database data. For Symfony apps, this can happen if inputs are not properly handled. Consider the following unsafe SQL query:
php
$query = "SELECT * FROM users WHERE username = '" . $_POST['username'] . "' AND password = '" . $_POST['password'] . "'";
Here, attackers could input SQL code as the username or password, potentially gaining unauthorized access.
How to Prevent SQL Injection in Symfony
Symfony provides tools that, when used correctly, can prevent SQL Injection vulnerabilities. Here are the best practices, with examples, to secure your Symfony app.
1. Use Prepared Statements (Example Included)
Prepared statements ensure SQL queries are safely constructed by separating SQL code from user inputs. Here’s an example using Symfony's Doctrine ORM:
By using setParameter(), Symfony binds the input parameter safely, blocking potential injection attacks.
Using Free Tools for Vulnerability Assessment
To check your application’s security, visit our Free Tools page. Here’s a snapshot of the free tools page where you can scan your website for SQL Injection vulnerabilities:
These tools help you identify security issues and provide guidance on securing your Symfony application.
Example: Vulnerability Assessment Report
Once you’ve completed a vulnerability scan, you’ll receive a detailed report outlining detected issues and recommended fixes. Here’s an example screenshot of a vulnerability assessment report generated by our free tool:
This report gives insights into potential SQL Injection vulnerabilities and steps to improve your app’s security.

There are servers people set up and allow anyone to hack - some are realistic, and some are more instructive in nature. HackThisSite may be the most famous - someone asked on r/asknetsec if it’s actually useful, and the top response was that the absolute worst-case scenario is that you learn something new, you have a lot of fun, and then you find out later that MAYBE the techniques you used are out of date.
That’s not the worst case scenario. A worse scenario I can think of is that one of their website admins tries your password on your email, and that’s not even the worst case scenario...but the site is fairly famous now.
You can pass the first few levels just by fiddling with “inspect element.” From there, things get more interesting. You can pass one level with a SQL injection, meaning you enter a login page and instead of entering something like “admin” and “secretpassword” you enter something like OR 1=1 -- ' . What you’ve just entered is additional text interpreted as part of a command, so that as long as 1 = 1 (which, by the laws of logic, is always true) the rest of the command is ignored. You can use this to log in as anyone.
***
There are other, more interesting ways to go here. OverTheWire is like HackThisSite, but you actually use C coding and stage buffer overflow attacks. Then there’s Kali Linux, an offensive OS made popular by the first and only accurate hacking show on television (I suppose there’s also Silicon Valley and Nathan For You), and for testing you can download another VM, a target, called Metasploitable...an intentionally vulnerable version of Ubuntu.
You can hack that thing to your heart’s content, and it’s Linux. Linux, as Zhanghe once said, has been open source since the dawn of time.
***
Malware is getting really, really smart.
It used to be that there was just the Facebook message asking if you wanted to see a picture, or the hijacked AIM instructing you to download...uh...a picture. We were in 8th grade, and we would make fun of anyone who fell for this in order to mask the insecurity we felt the day before, when we fell for it ourselves.
Now there’s SEO malware - it exploits Google’s laws of SEO to get near the top of search results, and it lifts contents from public sites like Reddit so that when you research anything, you see a bunch of legitimate-looking text previewed. It redirects you to something asking you to hit authorize, and if you do it hijacks your browser and attempts to use that as a vector to get into the rest of your computer.
If you want to know if a website is safe, you can attempt to Google it without actually going to the site. But then, from there, you might encounter a top-rated site called scamadviser. Scamadviser is a scam. Don’t click on it.
There are also cybersecurity publications that end with things like .net, so malware sites spring up that just replace that with .com...you cannot make this stuff up. And it seems like there are holes in security everywhere. LinkedIn was compromised because some sysadmin had a vulnerable personal website hosted on a personal laptop, and the personal laptop had direct access to LinkedIn. A Saudi Arabia company ten times more valuable than Apple fell to phishing. And Twitter...I don’t even know what happened to Twitter, and how it caused Biden, Bill Gates, and Elon Musk to all simultaneously ask me to send them $1000 in bitcoin and they would send me back double.
****
In conclusion, if malware is this smart then we might as well learn how to take down some metasploitable virtual machines. It’s cheaper entertainment than Disney+ and it takes up less disc space than Counter Strike.
This isn’t usually the kind of thing I post about, but bear with me. I’m involved in a group that’s been poking at Pillowfort’s website looking for vulnerabilities, and we’ve found some extremely startling things that genuinely make me worry for the safety of the website and its users. Let me break it down.
Here’s a short list of some found vulnerabilities in order of severity, from greatest to least.
- SQL injection
The instance that was found has since been patched, but if there’s one instance of it there’s reason to believe that there’s more. Basically, this would have allowed anyone to access anything the website stores, including but not limited to: User emails, hashed passwords, private posts, messages. Not just see them, but also edit them. Someone exploiting this may as well have *full control* over Pillowfort apart from being able to run code on the server. A true worst case scenario, and one hell of a security blunder.
- XSS via angular template injection
Basically, in certain contexts it’s possible to have javascript made by an attacker run in someone else’s window, which can then pretty much do anything that user can do and see anything that user can see. A clever attacker can steal your session data to log in as you, and even more adventurous applications would involve automatically making it so you perform the XSS as well, spreading the code further and further. This sort of attack is exceptionally dangerous, and can be used to expose all sorts of information and make users take actions they hadn’t intended. Unblocking/blocking people, reblogging or liking posts, and in the most extreme scenario it could even be targeted against the admins or mods and have them perform actions like banning or deleting users arbitrarily.
- Angular 5 years out of date
The frontend framework Angular is severely outdated, and the version that they’re running at the moment has a list of vulnerabilities that can lead to XSS situations as described above. To bring the frontend framework up to date may very well require an entire rewrite due to breaking changes in Angular from one version to the next.
- Unprotected endpoints
Certain things were straight up not protected, allowing users to trick other users into clicking a link to ban or unban users from communities. There were also situations where users could post in conversations between two other users, and it would appear to those users as though the person they were in a conversation with said that. Leading to the potential for very nasty phishing attacks.
- CSS injection
Using this, people can change the style of pages however they wish. It can lead to other exploits, but it can be troublesome in its own right. A user could cause pages effected with this to rapidly flash, as an example.
Keep in mind that this site has been in development for five years now, and not only that but they’ve also been taking money for signups. I can’t claim to know how they’re handling payments, but based on everything I’ve personally seen and tested I wouldn’t trust them as a blogging platform, let alone send their server my credit card details.

You Do Not Need Any Prior Experience In Hacking Or Cybersecurity To Go Through This Course
Description
Welcome to – Learn Ethical Hacking From A-Z: Beginner To Expert Course! This practical, hands-on course was created for newbies – that’s to say, people with no prior training or knowledge in hacking and cybersecurity. The aim of this course is to give you the education not just to understand what black-hat hatters do and how, but also to learn exactly how to hack systems like a pro and win the cat and mouse game by securing systems like a professional security expert.
Blending practical work with solid theoretical training, we take you from the basics of ethical hacking through to mastery, giving you the training you need not just to hack, but also to secure against a hack.
While the theory is important, we understand that it can also be dry and uninspiring. For this reason, this course is packed with examples that you can follow. This practical focus starts from the beginning, where we will teach you about penetration testing and show you how to install the software required (Windows, Linux, and Mac OSX) and jump right into hacking.
Throughout, you will analyze and exploit various systems from regular websites through to sprawling networks, along with hacking servers and clients. More than just hacking, you’ll also learn how to conduct efficient penetration testing techniques.
This approach gives you the foundational education that you need not just to hack any given system, but also to secure it, with each module covering both sides of the coin. The course covers six main areas:
1: LEARN THE FUNDAMENTALS NECESSARY TO BECOME A HACKER
This foundational section gives you a full introduction to the basics of networking systems – how they communicate and work – and is designed to give you the knowledge you need to succeed in this course.
BASICS OF NETWORKING: Networking can be an intimidating topic, but don’t worry! We break down only the necessary things that you need to know in regards to networking and teach you important networking fundamentals SETTING UP A HACKING LAB: You can’t hack without a lab! We walk you step-by-step through the process of setting up your own hacking lab on your laptop or desktop computer!
LINUX + SCRIPTING BASICS: Hackers use Linux, which is an OS that the average person may have no experience with. We will go over Linux fundamentals so that you can easily navigate your way through Linux during this course. We also touch on a couple of scripting languages that are a MUST for any ethical hacker and teach you the basics of each one with practical examples.
HIDING YOUR IDENTITY ON THE WEB: If you are hacking on the internet, you need to learn how to remain anonymous. We will show you the tools and techniques that you can use to always remain anonymous and unknown on the internet.
2: LEARN HOW TO HACK NETWORKS
This section shows you how to test both wired and wireless systems. You will learn how to go from not having any access to a network to gaining access and being able to begin attacking systems on the network.
PRE-CONNECTION ATTACK: Not all attacks require you to be connected to the target or even know the password. Learn how to discover and manipulate devices connected to a network and gather information about your target.
GAIN ACCESS TO NETWORKS: Learn how to use the information you have about your target to crack the key and get the access password. This section covers multiple protocols including WEP, WPA, and WPA2.
POST-CONNECTION ATTACKS: With a key, you can now leverage powerful hacking techniques to get even more information. Learn how to see what users are doing on a network, inject code in pages, and more on wired and wireless networks
3: HOW TO GAIN ACCESS AND CONNECT TO NETWORKS
This section builds on the lessons learned in section one, showing you how you can get full control and hack into any computer system that you target. SERVER-SIDE ATTACK: Discover how to harvest information about your targeted system – its OS, open ports, and installed services – without user interaction. Then use this information to exploit vulnerabilities and generate reports.
CLIENT-SIDE ATTACK: Learn how to hack systems with no vulnerabilities by sneaking in with software updates or using backdoor trojan downloads.
You’ll also learn the art of social engineering – or tricking people into giving you information.
4: HOW TO LEVERAGE POST EXPLOITATION
This section shifts the focus on interacting with compromised systems. Now that you have gained access, you’ll learn how you can exploit these systems.
ACCESS FILE SYSTEMS: All systems have a wealth of files that you can now manipulate with your access. Learn how to access these systems and how to read, write, upload, and even execute files.
MAINTAIN ACCESS: Gaining access to a system and its files is only half of the battle. Learn how to maintain your access and frustrate efforts to secure it again so you can continue to exploit a system.
SPY ON YOUR TARGET: Learn how to capture any keystrokes on a keyboard, turn on a computer webcam, take screenshots, and even take control of the system to attack, hack, and access third-party networks and systems.
5: HOW TO HACK WEBSITES AND WEB APPS
In this section, you will learn more about how you can hack into websites and web applications using Kali Linux. You’ll also learn how web applications work – and how to find vulnerabilities within these applications for you to exploit.
> How to scan websites/web applications for vulnerabilities to exploit.
> How to Brute Force into web applications.
> Learn how to conduct SQL injection in web applications.
> How to conduct Cross-Site Request Forgery (CSRF).
> How to exploit File Inclusion Vulnerabilities.
> Learn how to exploit File Upload Vulnerabilities.
> How to automate attacking web applications using various tools.
> How to prevent and secure websites & apps yourself.

It’s important to understand the reason as to why these sort of attacks are possible and what it all boils down - mixing ‘data’ and ‘control’. XSS attacks rely on the fact that web pages served in our browser (i.e. serving data) are also able to run programs at the same (i.e. control). This is achieved through Javascript - the simple “<script></script>” tags embedded within the markup allow an attacker to run malicious code. This means they can potentially:
Modify user cookies - steal sessions, modify data, etc
Read and change browser DOM
Make XMLHttpRequests in the background to send off and receive data
Potentially fiddle with new HTML5 APIs involving webcam, location and file system
Non-Persistent Attacks
The first class of these attacks are non-persistent; they essentially involve serving up a web page which contains the malicious scripts. This can occur when a user enters data into a form which is reflected back to them, without sanitising the input. They also commonly occur when clicking on links through emails or forums; the link will actually go to the correct site, but will execute a script on the side.
Persistent Attacks
These are the more commonly used and impactful attacks; they rely on a failure of servers to sanitise inputs in forms from Javascript code which results in distributing malicious code to users. For example, let’s say Bob is a regular contributor on the forum SecurityWorld, where you can chat about all things security! After an attack earlier this year, the owner had ramped up security and written a nifty script to parse out any SQL expressions in user input; however it was crappy and hardcoded.
Hacker Mallory comes along and hates the fact that people are spreading ‘useful ways to protect yourself’ when it comes to security; she decides she wants to break into Bob’s account and spread misinformation. The first thing she does is send a DM to Bob; however Mallory is very knowledgeable on XSS attacks and includes a script inside her message. The script fetches all the cookies in the browser and uploads them to a website at www.malloriescookiefactory.com.
The web server doesn’t see anything suss in the input and stores the message in the database. The next time Bob logs in, he accesses the message - the web page then serves him the page with the script included. All his cookies are uploaded to Mallory’s website - Mallory is then able to hijack his session and spread misinformation about the forum.
Protecting Against XSS Attacks
You can find more detailed methods of preventing against XSS attacks in the OWASP cheat sheets here and here. I will summarise the 3 basic concepts however in these protections:
Escaping - rewrite inputs in such a way that nothing is executed if they are served to a user
Validating - prevent special character inputs in forms unless necessary
Sanitising - similar to escaping, except completely removing the problematic characters
In terms of protecting the cookies from being hijacked there are also a number of steps that can be taken as well:
Enable HttpOnly attribute - cookies only submitted to domain of origin
Use Secure attribute - cookies only sent over secure channels
X-XSS protection response headers - feature in the header which prevents pages from loading when they detect an XSS attack
HTTP content security policy headers - allows you to define what and where resources can be loaded from
I also gave a sample attack on HackThisSite - Realistic #9; however the domain used in the injection was fake and only to show the concept.
