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

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

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
