As many as 29 different router models from DrayTek have been identified as affected by a new critical, unauthenticated, remote code execution vulnerability that, if successfully exploited, could lead to full compromise of the device and unauthorized access to the broader network. "The attack can be performed without user interaction if the management interface of the device has been configured

By Edmund Brumaghin, Azim Khodjibaev and Matt Thaxton, with contributions from Arnaud Zobec. Executive Summary Dark Utilities, released in early 2022, is a platform that provides full-featured C2 capabilities to adversaries. It is marketed as a means to enable remote access, command execution, distributed denial-of-service (DDoS) attacks and cryptocurrency mining operations on infected systems. Payloads provided by the platform support Windows, Linux and Python-based implementations and are hosted within the Interplanetary File System (IPFS), making them resilient to content moderation or law enforcement intervention. Since its initial release, we've observed malware samples in the wild leveraging it to facilitate remote access and cryptocurrency mining. What is "Dark Utilities?" In early 2022, a new C2 platform called "Dark Utilities" was established, offering a variety of services such as remote system access, DDoS capabilities and cryptocurrency mining. The operators of the s...

We spend a lot of time preparing for Blackhat, and as part of putting together content for the show, one of our best, Lurene Grenier, submitted an unexpected piece of content: a poem. Now this poem isn't our regular security research or a shiny piece of corporate correspondence (which we would never do anyways) — but it is raw, and it is painful and it is brilliant. And it raises a number of issues that Cisco takes very seriously, including work-life balance and mental health. In particular, by my interpretation, it speaks about early-in-career work-life balance. I know at that point in my career I felt grateful just to be in the industry while at the same time I felt powerless to advocate for myself in the face of the overwhelming demands of the workplace. This poem hit me hard, and in truth I wouldn't want it published anywhere other than on the Talos blog. So we are presenting Lurene's words here, in hopes that they trigger important conversations and also to remind everyone to just...

Cisco on Wednesday rolled out patches to address eight security vulnerabilities, three of which could be weaponized by an unauthenticated attacker to gain remote code execution (RCE) or cause a denial-of-service (DoS) condition on affected devices. The most critical of the flaws impact Cisco Small Business RV160, RV260, RV340, and RV345 Series routers. Tracked as CVE-2022-20842 (CVSS score: 9.8)

The new program offers robust protection across all five data risk categories: cyber, human, application, operation, and environmental.

Researchers have disclosed a new offensive framework called Manjusaka that they call a "Chinese sibling of Sliver and Cobalt Strike." "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

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...

OpenZeppelin Contracts is a library for secure smart contract development. This issue concerns instances of Governor that use the module `GovernorVotesQuorumFraction`, a mechanism that determines quorum requirements as a percentage of the voting token's total supply. In affected instances, when a proposal is passed to lower the quorum requirements, past proposals may become executable if they had been defeated only due to lack of quorum, and the number of votes it received meets the new quorum requirement. Analysis of instances on chain found only one proposal that met this condition, and we are actively monitoring for new occurrences of this particular issue. This issue has been patched in v4.7.2. Users are advised to upgrade. Users unable to upgrade should consider avoiding lowering quorum requirements if a past proposal was defeated for lack of quorum.

OpenZeppelin Contracts is a library for secure smart contract development. Contracts using the cross chain utilities for Arbitrum L2, `CrossChainEnabledArbitrumL2` or `LibArbitrumL2`, will classify direct interactions of externally owned accounts (EOAs) as cross chain calls, even though they are not started on L1. This issue has been patched in v4.7.2. Users are advised to upgrade. There are no known workarounds for this issue.

PyroCMS v3.9 was discovered to contain multiple cross-site scripting (XSS) vulnerabilities.
