Hackers are using a custom Flipper Zero firmware to bypass security protections in automotive key fobs, putting millions of vehicles at risk.
Hackers have a new way to break into – or even steal – your car, and all it takes is the push of a button. Malicious actors are circumventing modern security protections in automotive key fobs, researchers warn, putting millions of vehicles at risk.
The hack works by intercepting and cloning a key fob’s radio signal, using custom firmware built for the Flipper Zero, a handheld device designed for analyzing and testing wireless communication protocols.
It bypasses a security mechanism known as rolling codes, designed to prevent thieves from reusing captured key fob signals to unlock a car. Each time the key fob is pressed, an internal algorithm generates a new, one-time-use code, leading the vehicle to unlock only if the code is confirmed to be valid.
But the new hack sidesteps these protections by exploiting the rolling code algorithm to calculate valid key fob commands based on a single intercepted signal.
“I can sit in a parking lot and wait for someone to lock their car, and immediately I get all their fob buttons,” Jeremy Yablan, a hacker known online as RocketGod, told Straight Arrow News. “Other attacks are tricks. This one just captures a single keypress and decodes all buttons and rolling codes in an instant. You open your trunk – the bad guy has your entire fob.”
Yablan described the attack as “ridiculously fast and easy.”
Many vehicles vulnerable
SAN obtained a copy of the firmware and tested the attack in a controlled setting with the permission of vehicle owners. In one case, capturing a single unlock signal allowed the Flipper Zero to repeatedly lock, unlock and open the trunk of the target car.
The hack also disabled the original key fob until it was manually reset.
Vehicles vulnerable to the attack include numerous models manufactured by Chrysler, Dodge, Fiat, Ford, Hyundai, Jeep, Kia, Mitsubishi and Subaru, according to an infographic provided with the firmware. The infographic says updates to attack other car makers, such as Honda, are “in development.” It also mentions high-end car companies such as Alfa Romeo, Ferrari and Maserati.
Numerous car companies listed as susceptible to attack did not respond to SAN’s requests for comment. James Bell, the head of corporate communications at Kia America, said his company “is not aware of this situation and therefore have no comment to offer.”
The team behind the Flipper Zero device, which does not endorse the custom firmware, did not respond to requests for comment.
Created by Russian hacker
The hack appears to be based on a 2022 attack known as “RollBack,” developed by researchers at CrySys Lab in Hungary. The researchers demonstrated how rolling code protections could be broken by capturing valid signals and replaying them in a specific order to bypass a vehicle’s code synchronization system.
The firmware for the Flipper Zero apparently was created by a Russian hacker. Advertisements for the firmware, which includes a serial lock designed to keep it from being distributed to additional users, show it being listed online for as much as $1,000.
The firmware obtained by SAN was a version that had its serial lock disabled by security researchers. The firmware’s creator told SAN that a newer version has since been developed. He shared an updated infographic that lists Suzuki as another vulnerable make.
SAN is not naming the hacker to avoid facilitating the sale of his firmware to potential thieves.
The freelance security researcher and YouTuber known as Talking Sasquach, who regularly covers the Flipper Zero, said the firmware’s creator is marketing the tool specifically to criminals.
‘Only a matter of time’
Protections against the attack are limited.
“There’s really not much people can do to protect themselves against this attack short of just not using your key fob and only using the keys,” Talking Sasquach said.
Given that many modern vehicles do not use traditional keys and rely entirely on key fobs, such workarounds are not viable for all drivers.
“Car companies could issue an update,” Talking Sasquach said, “but they’d have to pull in all of the vehicles and change their software and the key fob’s software, which would probably not be feasible, and a huge cost to manufacturers.”
Despite attempts by the firmware’s creator to limit its distribution, Yablan and other hackers have already managed to remove the built-in licensing restrictions.
The hack is likely to become more commonly used, security researcher Ryan Montgomery, founder of Pentester.com, told SAN.
“It’s only a matter of time,” he said, “before it gets leaked to the masses.”
securityweek.com - DragonForce says it stole more than 150 gigabytes of data from US department store chain Belk in a May cyberattack
The DragonForce ransomware gang has claimed responsibility for a disruptive cyberattack on US department store chain Belk.
The incident was identified on May 8 and prompted Belk to disconnect affected systems, restrict network access, reset passwords, and rebuild impacted systems, which disrupted the chain’s online and physical operations for several days. The company’s online store is still offline at the time of publication.
Belk’s investigation into the attack determined that hackers had access to its network between May 7 and May 11, and that they exfiltrated certain documents, including files containing personal information.
In a data breach notification submitted to the New Hampshire Attorney General’s Office, Belk said at least names and Social Security numbers were compromised in the attack.
The company is providing the impacted individuals with 12 months of free credit monitoring and identity restoration services, which also include up to $1 million identity theft insurance.
The company has not named the group responsible for the attack, but the DragonForce ransomware gang has claimed the incident on Monday, adding Belk to its Tor-based leak site.
Switzerland says a ransomware attack on the non-profit health foundation Radix that involved data being stolen and encrypted had also affected the federal administration.
The Radix Foundation, a not-for-profit organisation active in the field of health promotion, has been the victim of a ransomware attack, it was confirmed on Monday. The criminals stole and encrypted data, which they then published on the darknet.
The foundation contacted the National Cybersecurity Centre (NCSC) after carrying out an initial analysis of the situation, it announced on Monday. Radix’s clientele also includes various administrative units of the federal administration.
The aim is to determine which services and data are actually affected by the cyber attack. At no time were the hackers able to penetrate the systems of the federal administration, as the Radix Foundation itself does not have such direct access, the centre pointed out.
An AI Researcher at Neural Trust has discovered a novel jailbreak technique that defeats the safety mechanisms of today’s most advanced Large Language Models (LLMs). Dubbed the Echo Chamber Attack, this method leverages context poisoning and multi-turn reasoning to guide models into generating harmful content, without ever issuing an explicitly dangerous prompt.
Unlike traditional jailbreaks that rely on adversarial phrasing or character obfuscation, Echo Chamber weaponizes indirect references, semantic steering, and multi-step inference. The result is a subtle yet powerful manipulation of the model’s internal state, gradually leading it to produce policy-violating responses.
In controlled evaluations, the Echo Chamber attack achieved a success rate of over 90% on half of the categories across several leading models, including GPT-4.1-nano, GPT-4o-mini, GPT-4o, Gemini-2.0-flash-lite, and Gemini-2.5-flash. For the remaining categories, the success rate remained above 40%, demonstrating the attack's robustness across a wide range of content domains.
The Echo Chamber Attack is a context-poisoning jailbreak that turns a model’s own inferential reasoning against itself. Rather than presenting an overtly harmful or policy-violating prompt, the attacker introduces benign-sounding inputs that subtly imply unsafe intent. These cues build over multiple turns, progressively shaping the model’s internal context until it begins to produce harmful or noncompliant outputs.
The name Echo Chamber reflects the attack’s core mechanism: early planted prompts influence the model’s responses, which are then leveraged in later turns to reinforce the original objective. This creates a feedback loop where the model begins to amplify the harmful subtext embedded in the conversation, gradually eroding its own safety resistances. The attack thrives on implication, indirection, and contextual referencing—techniques that evade detection when prompts are evaluated in isolation.
Unlike earlier jailbreaks that rely on surface-level tricks like misspellings, prompt injection, or formatting hacks, Echo Chamber operates at a semantic and conversational level. It exploits how LLMs maintain context, resolve ambiguous references, and make inferences across dialogue turns—highlighting a deeper vulnerability in current alignment methods.
A detailed analysis of a multi-stage card skimming attack exploiting outdated Magento software and fake image files.
In today’s post we’re going to review a sophisticated, multi-stage carding attack on a Magento eCommerce website. This malware leveraged a fake gif image file, local browser sessionStorage data, and tampered with the website traffic using a malicious reverse-proxy server to facilitate the theft of credit card data, login details, cookies, and other sensitive data from the compromised website.
The client was experiencing some strange behaviour on their checkout page, including clients unable to input their card details normally, and orders not going through. They contacted us for assistance. Thinking this would be a straightforward case of credit card theft instead what we found was actually a fascinating and rather advanced malware which we will explore in detail in this post.
This update outlines what happened, what we’ve done so far, and the actions we are taking to prevent it from happening in the future.

In the last few days, many Tor relay operators - mainly hosting relay nodes on providers like Hetzner - began receiving abuse notices.
All the abuses reported many failed SSH login attempts - part of a brute force attack - coming from their Tor relays.
Tor relays normally only transport traffic between a guard and an exit node of the Tor network, and per-se should not perform any SSH connections to internet-facing hosts, let alone performing SSH brute force attacks.
