Apple’s Find My Network Can be Abused to Exfiltrate Data From Nearby Devices
Latest research has demonstrated a new exploit that enables arbitrary data to be uploaded from devices that are not connected to the Internet by simply sending "Find My Bluetooth" broadcasts to nearby Apple devices. "It's possible to upload arbitrary data from non-internet-connected devices by sending Find My [Bluetooth Low Energy] broadcasts to nearby Apple devices that then … [Read more...] about Apple’s Find My Network Can be Abused to Exfiltrate Data From Nearby Devices
Nearly All Wi-Fi Devices Are Vulnerable to New FragAttacks
Three design and multiple implementation flaws have been disclosed in IEEE 802.11 technical standard that undergirds Wi-Fi, potentially enabling an adversary to take control over a system and plunder confidential data. Called FragAttacks (short for FRgmentation and AGgregation attacks), the weaknesses impact all Wi-Fi security protocols, from Wired Equivalent Privacy (WEP) all … [Read more...] about Nearly All Wi-Fi Devices Are Vulnerable to New FragAttacks
Microsoft Finds ‘BadAlloc’ Flaws Affecting Wide-Range of IoT and OT Devices
Microsoft researchers on Thursday disclosed two dozen vulnerabilities affecting a wide range of Internet of Things (IoT) and Operational Technology (OT) devices used in industrial, medical, and enterprise networks that could be abused by adversaries to execute arbitrary code and even cause critical systems to crash. "These remote code execution (RCE) vulnerabilities cover more … [Read more...] about Microsoft Finds ‘BadAlloc’ Flaws Affecting Wide-Range of IoT and OT Devices
New NAME:WRECK Vulnerabilities Impact Nearly 100 Million IoT Devices
Security researchers have uncovered nine vulnerabilities affecting four TCP/IP stacks impacting more than 100 million consumer and enterprise devices that could be exploited by an attacker to take control of a vulnerable system. Dubbed "NAME:WRECK" by Forescout and JSOF, the flaws are the latest in series of studies undertaken as part of an initiative called Project Memoria to … [Read more...] about New NAME:WRECK Vulnerabilities Impact Nearly 100 Million IoT Devices
Secret Chat in Telegram Left Self-Destructing Media Files On Devices
Popular messaging app Telegram fixed a privacy-defeating bug in its macOS app that made it possible to access self-destructing audio and video messages long after they disappeared from secret chats. The vulnerability was discovered by security researcher Dhiraj Mishra in version 7.3 of the app, who disclosed his findings to Telegram on December 26, 2020. The issue has since … [Read more...] about Secret Chat in Telegram Left Self-Destructing Media Files On Devices
New Attack Could Let Remote Hackers Target Devices On Internal Networks
A newly devised variant of the NAT Slipstreaming attack can be leveraged to compromise and expose any device in an internal network, according to the latest research. Detailed by enterprise IoT security firm Armis, the new attack (CVE-2020-16043 and CVE-2021-23961) builds on the previously disclosed technique to bypass routers and firewalls and reach any unmanaged device within … [Read more...] about New Attack Could Let Remote Hackers Target Devices On Internal Networks
Attackers Abusing Citrix NetScaler Devices to Launch Amplified DDoS Attacks
Citrix has issued an emergency advisory warning its customers of a security issue affecting its NetScaler application delivery controller (ADC) devices that attackers are abusing to launch amplified distributed denial-of-service (DDoS) attacks against several targets. "An attacker or bots can overwhelm the Citrix ADC [Datagram Transport Layer Security] network throughput, … [Read more...] about Attackers Abusing Citrix NetScaler Devices to Launch Amplified DDoS Attacks
Wormable Gitpaste-12 Botnet Returns to Target Linux Servers, IoT Devices
A new wormable botnet that spreads via GitHub and Pastebin to install cryptocurrency miners and backdoors on target systems has returned with expanded capabilities to compromise web applications, IP cameras, and routers. Early last month, researchers from Juniper Threat Labs documented a crypto-mining campaign called "Gitpaste-12," which used GitHub to host malicious code … [Read more...] about Wormable Gitpaste-12 Botnet Returns to Target Linux Servers, IoT Devices
Amnesia:33 — Critical TCP/IP Flaws Affect Millions of IoT Devices
Cybersecurity researchers disclosed a dozen new flaws in multiple widely-used embedded TCP/IP stacks impacting millions of devices ranging from networking equipment and medical devices to industrial control systems that could be exploited by an attacker to take control of a vulnerable system. Collectively called "AMNESIA:33" by Forescout researchers, it is a set of 33 … [Read more...] about Amnesia:33 — Critical TCP/IP Flaws Affect Millions of IoT Devices
