Slashdot: New Android Malware Uses VNC To Spy and Steal Passwords From Victims

New Android Malware Uses VNC To Spy and Steal Passwords From Victims
Published on July 31, 2021 at 07:40AM
A previously undocumented Android-based remote access trojan (RAT) has been found to use screen recording features to steal sensitive information on the device, including banking credentials, and open the door for on-device fraud. The Hacker News reports: Dubbed "Vultur" due to its use of Virtual Network Computing (VNC)'s remote screen-sharing technology to gain full visibility on targeted users, the mobile malware was distributed via the official Google Play Store and masqueraded as an app named "Protection Guard," attracting over 5,000 installations. Banking and crypto-wallet apps from entities located in Italy, Australia, and Spain were the primary targets. "For the first time we are seeing an Android banking trojan that has screen recording and keylogging as the main strategy to harvest login credentials in an automated and scalable way," researchers from ThreatFabric said in a write-up shared with The Hacker News. "The actors chose to steer away from the common HTML overlay development we usually see in other Android banking Trojans: this approach usually requires a larger time and effort investment from the actors to create multiple overlays capable of tricking the user. Instead, they chose to simply record what is shown on the screen, effectively obtaining the same end result." Vultur [...] takes advantage of accessibility permissions to capture keystrokes and leverages VNC's screen recording feature to stealthily log all activities on the phone, thus obviating the need to register a new device and making it difficult for banks to detect fraud. What's more, the malware employs ngrok, a cross-platform utility used to expose local servers behind NATs and firewalls to the public internet over secure tunnels, to provide remote access to the VNC server running locally on the phone. Additionally, it also establishes connections with a command-and-control (C2) server to receive commands over Firebase Cloud Messaging (FCM), the results of which, including extracted data and screen captures, are then transmitted back to the server. ThreatFabric's investigation also connected Vultur with another well-known piece of malicious software named Brunhilda, a dropper that utilizes the Play Store to distribute different kinds of malware in what's called a "dropper-as-a-service" (DaaS) operation, citing overlaps in the source code and C2 infrastructure used to facilitate attacks. These ties, the Amsterdam-based cybersecurity services company said, indicate Brunhilda to be a privately operating threat actor that has its own dropper and proprietary RAT Vultur.

Slashdot: AT&T Says Leaked Data of 70 Million People Is Not From Its Systems

AT&T Says Leaked Data of 70 Million People Is Not From Its Systems Published on March 20, 2024 at 02:15AM An anonymous reader quotes a report from BleepingComputer: AT&T says a massive trove of data impacting 71 million people did not originate from its systems after a hacker leaked it on a cybercrime forum and claimed it was stolen in a 2021 breach of the company. While BleepingComputer has not been able to confirm the legitimacy of all the data in the database, we have confirmed some of the entries are accurate, including those whose data is not publicly accessible for scraping. The data is from an alleged 2021 AT&T data breach that a threat actor known as ShinyHunters attempted to sell on the RaidForums data theft forum for a starting price of $200,000 and incremental offers of $30,000. The hacker stated they would sell it immediately for $1 million. AT&T told BleepingComputer then that the data did not originate from them and that its systems were not breached. &q

Slashdot: US Plans $825 Million Investment For New York Semiconductor R&D Facility

US Plans $825 Million Investment For New York Semiconductor R&D Facility Published on November 02, 2024 at 03:00AM The Biden administration is investing $825 million in a new semiconductor research and development facility in Albany, New York. Reuters reports: The New York facility will be expected to drive innovation in EUV technology, a complex process necessary to make semiconductors, the U.S. Department of Commerce and Natcast, operator of the National Semiconductor Technology Center (NTSC) said. The launch of the facility "represents a key milestone in ensuring the United States remains a global leader in innovation and semiconductor research and development," Commerce Secretary Gina Raimondo said. From the U.S. Department of Commerce press release: EUV Lithography is essential for manufacturing smaller, faster, and more efficient microchips. As the semiconductor industry pushes the limits of Moore's Law, EUV lithography has emerged as a critical technology to

Slashdot: AT&T, T-Mobile Prep First RedCap 5G IoT Devices

AT&T, T-Mobile Prep First RedCap 5G IoT Devices Published on October 15, 2024 at 03:20AM The first 5G Internet of Things (IoT) devices are launching soon. According to Fierce Wireless, T-Mobile plans to launch its first RedCap devices by the end of the year, while AT&T's devices are expected sometime in 2025. From the report: All of this should pave the way for higher performance 5G gadgets to make an impact in the world of IoT. RedCap, which stands for reduced capabilities, was introduced as part of the 3GPP's Release 17 5G standard, which was completed -- or frozen in 3GPP terms -- in mid-2022. The specification, which is also called NR-Light, is the first 5G-specific spec for IoT. RedCap promises to offer data transfer speeds of between 30 Mbps to 80 Mbps. The RedCap spec greatly reduces the bandwidth needed for 5G, allowing the signal to run in a 20 MHz channel rather than the 100 MHz channel required for full scale 5G communications.
