Alert: OracleIV DDoS Botnet Targets Public Docker Engine APIs to Hijack Containers

Alert: OracleIV DDoS Botnet Targets Public Docker Engine APIs to Hijack Containers

Nov 14, 2023 Cloud Security / Malware
Publicly-accessible Docker Engine API instances are being targeted by threat actors as part of a campaign designed to co-opt the machines into a distributed denial-of-service (DDoS) botnet dubbed  OracleIV . "Attackers are exploiting this misconfiguration to deliver a malicious Docker container, built from an image named 'oracleiv_latest' and containing Python malware compiled as an ELF executable," Cado researchers Nate Bill and Matt Muir  said . The malicious activity starts with attackers using an HTTP POST request to Docker's API to retrieve a malicious image from Docker Hub, which, in turn, runs a command to retrieve a shell script (oracle.sh) from a command-and-control (C&C) server. Oracleiv_latest  purports to be a MySQL image for docker and has been pulled 3,500 times to date. In a perhaps not-so-surprising twist, the image also includes additional instructions to fetch an XMRig miner and its configuration from the same server. That said, the clo

This Cloud Botnet Has Hijacked 30,000 Systems to Mine Cryptocurrencies

Jul 20, 2022
The 8220 cryptomining group has expanded in size to encompass as many as 30,000 infected hosts, up from 2,000 hosts globally in mid-2021. "8220 Gang is one of the many low-skill crimeware gangs we continually observe infecting cloud hosts and operating a botnet and cryptocurrency miners through known vulnerabilities and remote access brute forcing infection vectors," Tom Hegel of SentinelOne  said  in a Monday report. The growth is said to have been fueled through the use of Linux and common cloud application vulnerabilities and poorly secured configurations for services such as Docker, Apache WebLogic, and Redis. Active since early 2017, the Chinese-speaking, Monero-mining threat actor was most recently  seen  targeting i686 and x86_64 Linux systems by means of weaponizing a newly disclosed remote code execution exploit for Atlassian Confluence Server (CVE-2022-26134) to drop the PwnRig miner payload. "Victims are not targeted geographically, but simply identifie
How to Achieve the Best Risk-Based Alerting (Bye-Bye SIEM)

How to Achieve the Best Risk-Based Alerting (Bye-Bye SIEM)

Feb 19, 2024Network Detection and Response
Did you know that Network Detection and Response (NDR) has become the most effective technology to detect cyber threats? In contrast to SIEM, NDR offers adaptive cybersecurity with reduced false alerts and efficient threat response. Are you aware of  Network Detection and Response (NDR)  and how it's become the most effective technology to detect cyber threats?  NDR massively upgrades your security through risk-based alerting, prioritizing alerts based on the potential risk to your organization's systems and data. How? Well, NDR's real-time analysis, machine learning, and threat intelligence provide immediate detection, reducing alert fatigue and enabling better decision-making. In contrast to SIEM, NDR offers adaptive cybersecurity with reduced false positives and efficient threat response. Why Use Risk-Based Alerting? Risk-based alerting is an approach where security alerts and responses are prioritized based on the level of risk they pose to an organization's system
Abcbot Botnet Linked to Operators of Xanthe Cryptomining malware

Abcbot Botnet Linked to Operators of Xanthe Cryptomining malware

Jan 10, 2022
New research into the infrastructure behind an emerging DDoS botnet named Abcbot has uncovered "clear" links with a cryptocurrency-mining botnet attack that came to light in December 2020. Attacks involving Abcbot, first  disclosed  by Qihoo 360's Netlab security team in November 2021, are  triggered  via a malicious shell script that targets insecure cloud instances operated by cloud service providers such as Huawei, Tencent, Baidu, and Alibaba Cloud to download malware that co-opts the machine to a botnet, but not before terminating processes from competing threat actors and establishing persistence. The shell script in question is itself an iteration of an earlier version originally  discovered  by Trend Micro in October 2021 hitting vulnerable ECS instances inside Huawei Cloud. But in an interesting twist, continued analysis of the botnet by mapping all known Indicators of Compromise (IoCs), including IP addresses, URLs, and samples, has revealed Abcbot's cod

On-Demand Webinar: Into the Cryptoverse

On-Demand Webinar: Into the Cryptoverse

Nov 17, 2021
In the span of a few years, cryptocurrencies have gone from laughingstock and novelty to a serious financial instrument, and a major sector in high-tech. The price of Bitcoin and Ethereum has gone from single dollars to thousands, and they're increasingly in the mainstream.  This is undoubtedly a positive development, as it opens new avenues for finance, transactions, tech developments, and more. Unfortunately, no innovation is without its dark side, and the crypto industry is no exception. A new webinar from XDR provider Cynet ( you can see it here ) dives deeper into this dark corner to explore the intersection of cybersecurity and cryptocurrency.  The first question is how, exactly, cryptocurrency creates security vulnerabilities for organizations. There's no single answer, and in many cases, the results are more indirect. This bears closer inspection, and the webinar, led by Cynet  CyOps Analyst  Ronen Ahdut, studies the different ways cryptocurrencies are used by attackers.  I
