Zerobot Botnet Emerges as a Growing Threat with New Exploits and Capabilities

Zerobot Botnet Emerges as a Growing Threat with New Exploits and Capabilities

Dec 22, 2022 Internet of Things / Patch Management
The  Zerobot  DDoS botnet has received substantial updates that expand on its ability to target more internet-connected devices and scale its network. Microsoft Threat Intelligence Center (MSTIC) is tracking the ongoing threat under the moniker DEV-1061, its designation for unknown, emerging, or developing activity clusters. Zerobot,  first documented  by Fortinet FortiGuard Labs earlier this month, is a Go-based malware that propagates through vulnerabilities in web applications and IoT devices like firewalls, routers, and cameras. "The most recent distribution of Zerobot includes additional capabilities, such as exploiting vulnerabilities in Apache and Apache Spark ( CVE-2021-42013  and  CVE-2022-33891  respectively), and new DDoS attack capabilities," Microsoft researchers  said . Also called ZeroStresser by its operators, the malware is offered as a DDoS-for-hire service to other criminal actors, with the botnet advertised for sale on various social media networks.

KmsdBot Botnet Suspected of Being Used as DDoS-for-Hire Service

Dec 20, 2022 Server Security / Cyber Attacks
An ongoing analysis of the  KmsdBot  botnet has raised the possibility that it's a DDoS-for-hire service offered to other threat actors. This is based on the different industries and geographies that were attacked, web infrastructure company Akamai said. Among the notable targets included  FiveM  and  RedM , which are game modifications for Grand Theft Auto V and Red Dead Redemption 2, as well as luxury brands and security firms. KmsdBot is a  Go-based malware  that leverages SSH to infect systems and carry out activities like cryptocurrency mining and launch commands using TCP and UDP to mount distributed denial-of-service (DDoS) attacks. However, a lack of an error-checking mechanism in the malware source code caused the criminal operators to inadvertently  crash their own botnet  last month. "Based on observed IPs and domains, the majority of the victims are located in Asia, North America, and Europe," Akamai researchers Larry W. Cashdollar and Allen West  said .

Researchers Warn of New Go-based Malware Targeting Windows and Linux Systems

Sep 28, 2022
A new, multi-functional Go-based malware dubbed  Chaos  has been rapidly growing in volume in recent months to ensnare a wide range of Windows, Linux, small office/home office (SOHO) routers, and enterprise servers into its botnet. "Chaos functionality includes the ability to enumerate the host environment, run remote shell commands, load additional modules, automatically propagate through stealing and brute-forcing SSH private keys, as well as launch DDoS attacks," researchers from Lumen's Black Lotus Labs  said  in a write-up shared with The Hacker News. A majority of the bots are located in Europe, specifically Italy, with other infections reported in China and the U.S., collectively representing "hundreds of unique IP addresses" over a one-month time period from mid-June through mid-July 2022. Written in Chinese and leveraging China-based infrastructure for command-and-control, the botnet joins a long list of malware that are designed to establish persi
New 'ParseThru' Parameter Smuggling Vulnerability Affects Golang-based Applications

New 'ParseThru' Parameter Smuggling Vulnerability Affects Golang-based Applications

Aug 02, 2022
Security researchers have discovered a new vulnerability called  ParseThru  affecting Golang-based applications that could be abused to gain unauthorized access to cloud-based applications. "The newly discovered vulnerability allows a threat actor to bypass validations under certain conditions, as a result of the use of unsafe URL parsing methods built in the language," Israeli cybersecurity firm Oxeye said in a report shared with The Hacker News. The issue, at its core, has to do with inconsistencies stemming from changes introduced to Golang's URL parsing logic that's implemented in the "net/url" library. While versions of the programming language prior to 1.17 treated semicolons as a valid query delimiter (e.g., example.com?a=1;b=2&c=3), this behavior has since been modified to throw an error upon finding a query string containing a semicolon. "The net/url and net/http packages used to accept ";" (semicolon) as a setting separat
