A pair of reports from cybersecurity firms SEKOIA and Trend Micro sheds light on a new campaign undertaken by a Chinese threat actor named Lucky Mouse that involves leveraging a trojanized version of a cross-platform messaging app to backdoor systems. Infection chains leverage a chat application called MiMi, with its installer files compromised to download and install HyperBro samples for the

Ubuntu Security Notice 5566-1 - Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service or execute arbitrary code. It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code.

Over a dozen military-industrial complex enterprises and public institutions in Afghanistan and Europe have come under a wave of targeted attacks since January 2022 to steal confidential data by simultaneously making use of six different backdoors. Russian cybersecurity firm Kaspersky attributed the attacks "with a high degree of confidence" to a China-linked threat actor tracked by Proofpoint

Ubuntu Security Notice 5545-1 - Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel did not properly perform data validation. A local attacker could use this to escalate privileges in certain situations.

Ubuntu Security Notice 5544-1 - It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Felix Fu discovered that the Sun RPC implementation in the Linux kernel did not properly handle socket states, leading to a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service or execute arbitrary code.

By Asheer Malhotra and Vitor Ventura. Cisco Talos recently discovered a new attack framework called "Manjusaka" being used in the wild that has the potential to become prevalent across the threat landscape. This framework is advertised as an imitation of the Cobalt Strike framework. The implants for the new malware family are written in the Rust language for Windows and Linux. A fully functional version of the command and control (C2), written in GoLang with a User Interface in Simplified Chinese, is freely available and can generate new implants with custom configurations with ease, increasing the likelihood of wider adoption of this framework by malicious actors. We recently discovered a campaign in the wild using lure documents themed around COVID-19 and the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province. These maldocs ultimately led to the delivery of Cobalt Strike beacons on infected endpoints. We have observed the same threat actor using the Cobalt Strike beac...
