Microsoft disclosed 83 vulnerabilities across the company’s hardware and software line, including two issues that are actively being exploited in the wild, continuing a trend of zero-days appearing in Patch Tuesdays over the past few months.

Cisco Talos has identified a new espionage oriented threat actor, which we are naming “YoroTrooper,” targeting a multitude of entities in Europe and Turkey.

### Impact Due to the underlying implementation of `.ToString()`, it's possible to execute arbitrary JavaScript, or to achieve a denial-of-service, if a binding parameter is a crafted Object. Users of `sqlite3` v5.0.0 - v5.1.4 are affected by this. ### Patches Fixed in v5.1.5. All users are recommended to upgrade to v5.1.5 or later. ### Workarounds * Ensure there is sufficient sanitization in the parent application to protect against invalid values being supplied to binding parameters. ### References * Commit: https://github.com/TryGhost/node-sqlite3/commit/edb1934dd222ae55632e120d8f64552d5191c781 ### For more information If you have any questions or comments about this advisory: * Email us at [[email protected]](mailto:[email protected]) Credits: Dave McDaniel of Cisco Talos

When Dave Liebenberg started his first day at Talos, he had never even opened Terminal on a Mac before — let alone written a Snort rule or infiltrated a dark web forum.

A vulnerability in the upgrade signature verification of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an unauthenticated, local attacker to provide an unauthentic upgrade file for upload. This vulnerability is due to insufficient cryptographic signature verification of upgrade files. An attacker could exploit this vulnerability by providing an administrator with an unauthentic upgrade file. A successful exploit could allow the attacker to fully compromise the Cisco NFVIS system.

An updated version of a botnet malware called Prometei has infected more than 10,000 systems worldwide since November 2022. The infections are both geographically indiscriminate and opportunistic, with a majority of the victims reported in Brazil, Indonesia, and Turkey. Prometei, first observed in 2016, is a modular botnet that features a large repertoire of components and several proliferation

A vulnerability in the bidirectional forwarding detection (BFD) hardware offload feature of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers, ASR 9902 Compact High-Performance Routers, and ASR 9903 Compact High-Performance Routers could allow an unauthenticated, remote attacker to cause a line card to reset, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of malformed BFD packets that are received on line cards where the BFD hardware offload feature is enabled. An attacker could exploit this vulnerability by sending a crafted IPv4 BFD packet to an affected device. A successful exploit could allow the attacker to cause line card exceptions or a hard reset, resulting in loss of traffic over that line card while the line card reloads.

A vulnerability in the GRand Unified Bootloader (GRUB) for Cisco IOS XR Software could allow an unauthenticated attacker with physical access to the device to view sensitive files on the console using the GRUB bootloader command line. This vulnerability is due to the inclusion of unnecessary commands within the GRUB environment that allow sensitive files to be viewed. An attacker could exploit this vulnerability by being connected to the console port of the Cisco IOS XR device when the device is power-cycled. A successful exploit could allow the attacker to view sensitive files that could be used to conduct additional attacks against the device.

Don't expect AI to suddenly start stealing jobs or making malware more powerful.

Prometei botnet continued its activity since Cisco Talos first reported about it in 2020. Since November 2022, we have observed Prometei improving the infrastructure components and capabilities.
