Cisco on Monday updated an advisory to warn customers of active exploitation of a decade-old security flaw impacting its Adaptive Security Appliance (ASA). The vulnerability, tracked as CVE-2014-2120 (CVSS score: 4.3), concerns a case of insufficient input validation in ASA's WebVPN login page that could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a targeted user of the appliance. "An attacker could exploit this vulnerability by convincing a user to access a malicious link," Cisco noted in an alert released in March 2014. As of December 2, 2024, the networking equipment major has revised its bulletin to note that it has become aware of "additional attempted exploitation" of the vulnerability in the wild. The development comes shortly after cybersecurity firm CloudSEK revealed that the threat actors behind AndroxGh0st are leveraging an extensive list of security vulnerabilities in various internet-faci...

A threat actor named Matrix has been linked to a widespread distributed denial-of-service (DDoS) campaign that leverages vulnerabilities and misconfigurations in Internet of Things (IoT) devices to co-opt them into a disruptive botnet. "This operation serves as a comprehensive one-stop shop for scanning, exploiting vulnerabilities, deploying malware, and setting up shop kits, showcasing a do-it-all-yourself approach to cyberattacks," Assaf Morag, director of threat intelligence at cloud security firm Aqua, said . There is evidence to suggest that the operation is the work of a lone wolf actor, a script kiddie of Russian origin. The attacks have primarily targeted IP addresses located in China, Japan, and to a lesser extent Argentina, Australia, Brazil, Egypt, India, and the U.S. The absence of Ukraine in the victimology footprint indicates that the attackers are purely driven by financial motivations, the cloud security firm said. The attack chains are characterized by ...

The malware known as Ngioweb has been used to fuel a notorious residential proxy service called NSOCKS, as well as by other services such as VN5Socks and Shopsocks5, new findings from Lumen Technologies reveal. "At least 80% of NSOCKS bots in our telemetry originate from the Ngioweb botnet, mainly utilizing small office/home office (SOHO) routers and IoT devices," the Black Lotus Labs team at Lumen Technologies said in a report shared with The Hacker News. "Two-thirds of these proxies are based in the U.S." "The network maintains a daily average of roughly 35,000 working bots, with 40% remaining active for a month or longer." Ngioweb, first documented by Check Point way back in August 2018 in connection with a Ramnit trojan campaign that distributed the malware, has been the subject of extensive analyses in recent weeks by LevelBlue and Trend Micro , the latter of which is tracking the financially motivated threat actor behind the operation as Wate...

The threat actors behind the AndroxGh0st malware are now exploiting a broader set of security flaws impacting various internet-facing applications, while also deploying the Mozi botnet malware. "This botnet utilizes remote code execution and credential-stealing methods to maintain persistent access, leveraging unpatched vulnerabilities to infiltrate critical infrastructures," CloudSEK said in a new report. AndroxGh0st is the name given to a Python-based cloud attack tool that's known for its targeting of Laravel applications with the goal of sensitive data pertaining to services like Amazon Web Services (AWS), SendGrid, and Twilio. Active since at least 2022, it has previously leveraged flaws in the Apache web server ( CVE-2021-41773 ), Laravel Framework ( CVE-2018-15133 ), and PHPUnit ( CVE-2017-9841 ) to gain initial access, escalate privileges, and establish persistent control over compromised systems. Earlier this January, U.S. cybersecurity and intelligence a...

German law enforcement authorities have announced the disruption of a criminal service called dstat[.]cc that made it possible for other threat actors to easily mount distributed denial-of-service (DDoS) attacks. "The platform made such DDoS attacks accessible to a wide range of users, even those without any in-depth technical skills of their own," the Federal Criminal Police Office (aka Bundeskriminalamt or BKA) said . "The use of stresser services to carry out DDoS attacks has recently become increasingly known in the context of police investigations." The BKA described dstat[.]cc as a platform that offered recommendations and evaluations of stresser services in order to conduct DDoS attacks against websites of interest and render them unresponsive. According to an alert published by Radware in January 2023, dstat[.]cc offered botnet owners the ability to assess the capacity and capabilities of their DDoS attack services. "Bot herders use DStat sites ...

Microsoft has revealed that a Chinese threat actor it tracks as Storm-0940 is leveraging a botnet called Quad7 to orchestrate highly evasive password spray attacks. The tech giant has given the botnet the name CovertNetwork-1658, stating the password spray operations are used to steal credentials from multiple Microsoft customers. "Active since at least 2021, Storm-0940 obtains initial access through password spray and brute-force attacks, or by exploiting or misusing network edge applications and services," the Microsoft Threat Intelligence team said . "Storm-0940 is known to target organizations in North America and Europe, including think tanks, government organizations, non-governmental organizations, law firms, defense industrial base, and others." Quad7, aka 7777 or xlogin, has been the subject of extensive analyses by Sekoia and Team Cymru in recent months. The botnet malware has been observed targeting several brands of SOHO routers and VPN appliances...

Federal prosecutors in the U.S. have charged two Sudanese brothers with running a distributed denial-of-service (DDoS) botnet for hire that conducted a record 35,000 DDoS attacks in a single year, including those that targeted Microsoft's services in June 2023. The attacks, which were facilitated by Anonymous Sudan's "powerful DDoS tool," singled out critical infrastructure, corporate networks, and government agencies in the United States and around the world, the U.S. Department of Justice (DoJ) said. Ahmed Salah Yousif Omer, 22, and Alaa Salah Yusuuf Omer, 27, have been charged with one count of conspiracy to damage protected computers. Ahmed Salah has also been charged with three counts of damaging protected computers. If convicted on all charges, Ahmed Salah faces a statutory maximum sentence of life in federal prison, while Alaa Salah faces a maximum sentence of five years in federal prison. The DDoS tool is said to have been disabled in March 2024, the same...

Cybersecurity researchers have discovered a new botnet malware family called Gorilla (aka GorillaBot) that draws its inspiration from the leaked Mirai botnet source code. Cybersecurity firm NSFOCUS, which identified the activity last month, said the botnet "issued over 300,000 attack commands, with a shocking attack density" between September 4 and September 27, 2024. No less than 20,000 commands designed to mount distributed denial-of-service (DDoS) attacks have been issued from the botnet every day on average. The botnet is said to have targeted more than 100 countries, attacking universities, government websites, telecoms, banks, gaming, and gambling sectors. China, the U.S., Canada, and Germany have emerged as the most attacked countries. The Beijing-headquartered company said Gorilla primarily uses UDP flood , ACK BYPASS flood, Valve Source Engine (VSE) flood , SYN flood , and ACK flood to conduct the DDoS attacks, adding the connectionless nature of the UDP prot...

Cloudflare has disclosed that it mitigated a record-breaking distributed denial-of-service (DDoS) attack that peaked at 3.8 terabits per second (Tbps) and lasted 65 seconds. The web infrastructure and security company said it fended off "over one hundred hyper-volumetric L3/4 DDoS attacks throughout last month, with many exceeding 2 billion packets per second (Bpps) and 3 terabits per second (Tbps)." The hyper-volumetric L3/4 DDoS attacks have been ongoing since early September 2024, it noted, adding they targeted multiple customers in the financial services, Internet, and telecommunication industries. The activity has not been attributed to any specific threat actor. The previous record for the largest volumetric DDoS attack hit a peak throughput of 3.47 Tbps in November 2021 , targeting an unnamed Microsoft Azure customer in Asia. The attacks leverage the User Datagram Protocol (UDP) protocol on a fixed port, with the flood of packets originating from Vietnam, Russi...

Cybersecurity researchers have uncovered a new cryptojacking campaign targeting the Docker Engine API with the goal of co-opting the instances to join a malicious Docker Swarm controlled by the threat actor. This enabled the attackers to "use Docker Swarm's orchestration features for command-and-control (C2) purposes," Datadog researchers Matt Muir and Andy Giron said in an analysis. The attacks leverage Docker for initial access to deploy a cryptocurrency miner on compromised containers, while also fetching and executing additional payloads that are responsible for conducting lateral movement to related hosts running Docker, Kubernetes, or SSH. Specifically, this involves identifying unauthenticated and exposed Docker API endpoints using Internet scanning tools, such as masscan and ZGrab . On vulnerable endpoints, the Docker API is used to spawn an Alpine container and then retrieve an initialization shell script (init.sh) from a remote server ("solscan[.]liv...

Cybersecurity researchers have uncovered a never-before-seen botnet comprising an army of small office/home office (SOHO) and IoT devices that are likely operated by a Chinese nation-state threat actor called Flax Typhoon (aka Ethereal Panda or RedJuliett). The sophisticated botnet, dubbed Raptor Train by Lumen's Black Lotus Labs, is believed to have been operational since at least May 2020, hitting a peak of 60,000 actively compromised devices in June 2023. "Since that time, there have been more than 200,000 SOHO routers, NVR/DVR devices, network attached storage (NAS) servers, and IP cameras; all conscripted into the Raptor Train botnet, making it one of the largest Chinese state-sponsored IoT botnets discovered to-date," the cybersecurity company said in a 81-page report shared with The Hacker News. The infrastructure powering the botnet is estimated to have ensnared hundreds of thousands of devices since its formation, with the network powered by a three-tiered...

The operators of the mysterious Quad7 botnet are actively evolving by compromising several brands of SOHO routers and VPN appliances by leveraging a combination of both known and unknown security flaws. Targets include devices from TP-LINK, Zyxel, Asus, Axentra, D-Link, and NETGEAR, according to a new report by French cybersecurity company Sekoia. "The Quad7 botnet operators appear to be evolving their toolset, introducing a new backdoor and exploring new protocols, with the aim of enhancing stealth and evading the tracking capabilities of their operational relay boxes (ORBs)," researchers Felix Aimé, Pierre-Antoine D., and Charles M. said .  Quad7, also called 7777, was first publicly documented by independent researcher Gi7w0rm in October 2023, highlighting the activity cluster's pattern of ensnaring TP-Link routers and Dahua digital video recorders (DVRs) into a botnet. The botnet, which gets its name from the fact it opens TCP port 7777 on compromised devices, ...

A recently disclosed security flaw in OSGeo GeoServer GeoTools has been exploited as part of multiple campaigns to deliver cryptocurrency miners, botnet malware such as Condi and JenX, and a known backdoor called SideWalk. The security vulnerability is a critical remote code execution bug (CVE-2024-36401, CVSS score: 9.8) that could allow malicious actors to take over susceptible instances. In mid-July, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added it to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation. The Shadowserver Foundation said it detected exploitation attempts against its honeypot sensors starting July 9, 2024. According to Fortinet FortiGuard Labs, the flaw has been observed being used to deliver GOREVERSE, a reverse proxy server designed to establish a connection with a command-and-control (C2) server for post-exploitation activity. These attacks are said to target IT service providers in In...

A years-old high-severity flaw impacting AVTECH IP cameras has been weaponized by malicious actors as a zero-day to rope them into a botnet. CVE-2024-7029 (CVSS score: 8.7), the vulnerability in question, is a "command injection vulnerability found in the brightness function of AVTECH closed-circuit television (CCTV) cameras that allows for remote code execution (RCE)," Akamai researchers Kyle Lefton, Larry Cashdollar, and Aline Eliovich said . Details of the security shortcoming were first made public earlier this month by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), highlighting its low attack complexity and the ability to exploit it remotely. "Successful exploitation of this vulnerability could allow an attacker to inject and execute commands as the owner of the running process," the agency noted in an alert published August 1, 2024. It's worth noting that the issue remains unpatched. It impacts AVM1203 camera devices using firmwar...

Cybersecurity researchers have discovered a new variant of the Gafgyt botnet that's targeting machines with weak SSH passwords to ultimately mine cryptocurrency on compromised instances using their GPU computational power. This indicates that the "IoT botnet is targeting more robust servers running on cloud native environments," Aqua Security researcher Assaf Morag said in a Wednesday analysis. Gafgyt (aka BASHLITE, Lizkebab, and Torlus), known to be active in the wild since 2014, has a history of exploiting weak or default credentials to gain control of devices such as routers, cameras, and digital video recorders (DVRs). It's also capable of leveraging known security flaws in Dasan, Huawei, Realtek, SonicWall, and Zyxel devices. The infected devices are corralled into a botnet capable of launching distributed denial-of-service (DDoS) attacks against targets of interest. There is evidence to suggest that Gafgyt and Necro are operated by a threat group calle...
