Cybersecurity researchers have uncovered a new hacking technique that exploits vulnerabilities in eSIM technology, putting users at significant risk. This issue particularly affects the Kigen eUICC card, with over two billion IoT device SIMs activated as of December 2020, according to the Irish company’s website. The findings come from Security Explorations, a research lab affiliated with AG Security Research, which was awarded a $30,000 bounty by Kigen for their report. An eSIM, or embedded SIM, is a digital SIM card integrated into a device via software on an Embedded Universal Integrated Circuit Card (eUICC) chip. eSIMs enable users to activate cellular plans without needing a physical SIM card, while eUICC software facilitates the installation of operator profiles, remote provisioning, and SIM profile management.
eSIM Vulnerability in eUICC Cards Threatens Billions of IoT Devices to Cyber Attacks In a significant cybersecurity breakthrough, researchers have unveiled a vulnerability within the eSIM technology that could expose billions of Internet of Things (IoT) devices to malicious attacks. This issue specifically involves the Kigen eUICC card, which has…

THN Weekly Roundup: Key Cybersecurity Threats, Tools, and Practices (Nov 4 – Nov 10)
📅 Published: November 11, 2024
Category: Cybersecurity / Hacking News
⚠️ Picture this: the tools you rely on for online security—two-factor authentication, your car’s tech, and even your security software—have become covert accomplices for hackers. Sounds like a suspenseful plot, right? Yet, in 2024, this is the startling reality of cyber threats. Today’s adversaries are leveraging our trusted resources as hidden gateways, evading defenses without leaving a trace. For financial institutions, this development is particularly concerning. Modern malware doesn’t just compromise codes; it undermines the very trust that underpins digital banking. These advanced threats often stay one step ahead of our protective measures.
Moreover, critical infrastructure in our cities is under siege. Cybercriminals are infiltrating the very tools that operate these essential services, making detection and prevention increasingly challenging. It’s a tense game of cat and mouse, where every action heightens the stakes. As these threats escalate, let’s explore …

Stealthy New Ymir Ransomware Utilizes Memory Exploits to Target Corporate Networks
November 12, 2024
Cyber Attack / Cybercrime
Cybersecurity experts have identified a new ransomware variant, Ymir, which was deployed in an attack just two days after systems were compromised by RustyStealer, a type of credential-stealing malware. Kaspersky, a prominent Russian cybersecurity firm, noted that “Ymir ransomware features a distinctive mix of technical capabilities and tactics that bolster its effectiveness.” The attackers employed an unusual combination of memory management functions—malloc, memmove, and memcmp—to execute malicious code directly within system memory. This method diverges from the conventional execution flow found in common ransomware, significantly enhancing its stealth. Kaspersky reported observing this ransomware in an attack on an unnamed Colombian organization, with the threat actors leveraging stolen corporate credentials acquired through RustyStealer to gain unauthorized access.
