A new botnet Orchard Generates DGA Domains with Bitcoin Transaction Information
DGA is one of the classic techniques for botnets to hide their C2s, attacker only needs to selectively register a very small number of C2 domains, while for the defenders, it is difficult to determine in advance which domain names will be generated and registered.
Attackers leveraging Dark Utilities "C2aaS" platform in malware campaigns
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.
Manjusaka: A Chinese sibling of Sliver and Cobalt Strike
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 beacon and implants from the Manjusaka framework.
Microsoft links Raspberry Robin malware to Evil Corp attacks
Microsoft has discovered that an access broker it tracks as DEV-0206 uses the Raspberry Robin Windows worm to deploy a malware downloader on networks where it also found evidence of malicious activity matching Evil Corp tactics.
The risk of distributed denial-of-service attacks (DDoS) has never been greater. Over the past several years, organizations have encountered a deluge of DDoS extortion, novel threats, state-sponsored hacktivism, and unprecedented innovation in the threat landscape.

The Return of Candiru: Zero-days in the Middle East - Avast Threat Labs
We recently discovered a zero-day vulnerability in Google Chrome (CVE-2022-2294) when it was exploited in the wild in an attempt to attack Avast users in the Middle East. The vulnerability was a memory corruption in WebRTC that was abused to achieve shellcode execution in Chrome’s renderer process. We reported this vulnerability to Google, who patched it on July 4, 2022.

Flubot: the evolution of a notorious Android Banking Malware
Flubot is an Android based malware that has been distributed in the past 1.5 years in Europe, Asia and Oceania affecting thousands of devices of mostly unsuspecting victims. Like the majority of Android banking malware, Flubot abuses Accessibility Permissions and Services in order to steal the victim’s credentials, by detecting when the official banking application is open to show a fake web injection, a phishing website similar to the login form of the banking application. An important part of the popularity of Flubot is due to the distribution strategy used in its campaigns, since it has been using the infected devices to send text messages, luring new victims into installing the malware from a fake website. In this article we detail its development over time and recent developments regarding its disappearance, including new features and distribution campaigns.
