A newly discovered data exfiltration mechanism employs Ethernet cables as a "transmitting antenna" to stealthily siphon highly-sensitive data from air-gapped systems, according to the latest research. "It's interesting that the wires that came to protect the air-gap become the vulnerability of the air gap in this attack," Dr. Mordechai Guri, the head of R&D in the Cyber Security Research Center in the Ben Gurion University of the Negev in Israel, told The Hacker News. Dubbed " LANtenna Attack ," the novel technique enables malicious code in air-gapped computers to amass sensitive data and then encode it over radio waves emanating from Ethernet cables just as if they are antennas. The transmitted signals can then be intercepted by a nearby software-defined radio (SDR) receiver wirelessly, the data decoded, and sent to an attacker who is in an adjacent room. "Notably, the malicious code can run in an ordinary user-mode process and successful...

Cybersecurity researchers on Monday discovered misconfigurations across older versions of Apache Airflow instances belonging to a number of high-profile companies across various sectors, resulting in the exposure of sensitive credentials for popular platforms and services such as Amazon Web Services (AWS), Binance, Google Cloud Platform (GCP), PayPal, Slack, and Stripe. "These unsecured instances expose sensitive information of companies across the media, finance, manufacturing, information technology (IT), biotech, e-commerce, health, energy, cybersecurity, and transportation industries," Intezer said in a report shared with The Hacker News. Originally launched in June 2015,  Apache Airflow  is an open-source workflow management platform that enables programmatic scheduling and monitoring of workflows on AWS, GCP, Microsoft Azure, and other third-party services. It's also one of the most popular task orchestration tools, followed by Luigi, Kubeflow, and MLflow. It...

A previously undocumented threat actor has been identified as behind a string of attacks targeting fuel, energy, and aviation production industries in Russia, the U.S., India, Nepal, Taiwan, and Japan with the goal of stealing data from compromised networks. Cybersecurity company Positive Technologies dubbed the advanced persistent threat (APT) group ChamelGang — referring to their chameleellonic capabilities, including disguising "its malware and network infrastructure under legitimate services of Microsoft, TrendMicro, McAfee, IBM, and Google."  "To achieve their goal, the attackers used a trending penetration method—supply chain," the researchers  said  of one of the incidents investigated by the firm. "The group compromised a subsidiary and penetrated the target company's network through it. Trusted relationship attacks are rare today due to the complexity of their execution. Using this method […], the ChamelGang group was able to achieve its goal a...

Security teams at mid-sized organizations are constantly faced with the question of "what does success look like?". At ActZero, their continued data-driven approach to cybersecurity invites them to grapple daily with measuring, evaluating, and validating the work they do on behalf of their customers.  Like most, they initially turned toward the standard metrics used in cybersecurity, built around a "Mean Time to X" (MTTX) formula, where X indicates a specific milestone in the attack lifecycle. In this formula, these milestones include factors like Detect, Alert, Respond, Recover, or even Remediate when necessary. However, as they started to operationalize their unique  AI and machine-learning approach , they realized that "speed" measures weren't giving them a holistic view of the story. More importantly, simply measuring just speed wasn't as applicable in an industry where machine-driven alerts and responses were happening in fractions of secon...

Cybersecurity researchers have disclosed an unpatched flaw in Apple Pay that attackers could abuse to make an unauthorized Visa payment with a locked iPhone by taking advantage of the Express Travel mode set up in the device's wallet. "An attacker only needs a stolen, powered on iPhone. The transactions could also be relayed from an iPhone inside someone's bag, without their knowledge," a group of academics from the University of Birmingham and University of Surrey  said . "The attacker needs no assistance from the merchant and backend fraud detection checks have not stopped any of our test payments." Express Travel  is a feature that allows users of iPhone and Apple Watch to make quick contactless payments for public transit without having to wake or unlock the device, open an app, or even validate with Face ID, Touch ID or a passcode. The man-in-the-middle ( MitM ) replay and  relay attack , which involves bypassing the lock screen to make a payment t...
