Google's cloud division on Thursday disclosed it mitigated a series of HTTPS distributed denial-of-service (DDoS) attacks which peaked at 46 million requests per second (RPS), making it the largest such recorded to date. The attack, which occurred on June 1, targeting an unnamed Google Cloud Armor customer, is 76% larger than the 26 million RPS DDoS attack repealed by Cloudflare earlier this

Funds will support product development and market expansion for ThreatX, which delivers real-time protection for APIs and Web apps against complex botnets, DDoS, and multimode attacks.

Contentious edge case activities are no excuse for further delaying of ‘much overdue’ reform, say campaigners

Today, Talos is publishing a glimpse into the most prevalent threats we've observed between Aug. 5 and Aug. 12. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral characteristics, indicators of compromise, and discussing how our customers are automatically protected from these threats. As a reminder, the information provided for the following threats in this post is non-exhaustive and current as of the date of publication. Additionally, please keep in mind that IOC searching is only one part of threat hunting. Spotting a single IOC does not necessarily indicate maliciousness. Detection and coverage for the following threats is subject to updates, pending additional threat or vulnerability analysis. For the most current information, please refer to your Firepower Management Center, Snort.org, or ClamAV.net. For each threat described below, this blog post only lists 25...

A new botnet named Orchard has been observed using Bitcoin creator Satoshi Nakamoto's account transaction information to generate domain names to conceal its command-and-control (C2) infrastructure. "Because of the uncertainty of Bitcoin transactions, this technique is more unpredictable than using the common time-generated [domain generation algorithms], and thus more difficult to defend

A new IoT botnet malware dubbed RapperBot has been observed rapidly evolving its capabilities since it was first discovered in mid-June 2022. "This family borrows heavily from the original Mirai source code, but what separates it from other IoT malware families is its built-in capability to brute force credentials and gain access to SSH servers instead of Telnet as implemented in Mirai,"

Over the past few weeks, a Mirai variant appears to have made a pivot from infecting new servers to maintaining remote access.

A nascent service called Dark Utilities has already attracted 3,000 users for its ability to provide command-and-control (C2) services with the goal of commandeering compromised systems. "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," Cisco Talos said in a report shared

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...
