Europol Dismantles 27 DDoS Attack Platforms Across 15 Nations; Admins Arrested

Europol Dismantles 27 DDoS Attack Platforms Across 15 Nations; Admins Arrested

Dec 12, 2024 Cyber Crime / DDoS Attack
A global law enforcement operation has failed 27 stresser services that were used to conduct distributed denial-of-service (DDoS) attacks and took them offline as part of a multi-year international exercise called PowerOFF. The effort, coordinated by Europol and involving 15 countries, dismantled several booter and stresser websites, including zdstresser.net, orbitalstress.net, and starkstresser.net. These services typically employ botnet malware installed on compromised devices to launch attacks on behalf of paying customers against targets of their liking. In addition, three administrators associated with the illicit platforms have been arrested in France and Germany, with over 300 users identified for planned operational activities. "Known as 'booter' and 'stresser' websites, these platforms enabled cybercriminals and hacktivists to flood targets with illegal traffic, rendering websites and other web-based services inaccessible," Europol said in a stat...
Socks5Systemz Botnet Powers Illegal Proxy Service with 85,000+ Hacked Devices

Socks5Systemz Botnet Powers Illegal Proxy Service with 85,000+ Hacked Devices

Dec 09, 2024 Cloud Security / Botnet
A malicious botnet called Socks5Systemz is powering a proxy service called PROXY.AM, according to new findings from Bitsight. "Proxy malware and services enable other types of criminal activity adding uncontrolled layers of anonymity to the threat actors, so they can perform all kinds of malicious activity using chains of victim systems," the company's security research team said in an analysis published last week. The disclosure comes merely weeks after the Black Lotus Labs team at Lumen Technologies revealed that systems compromised by another malware known as Ngioweb are being abused as residential proxy servers for NSOCKS. Socks5Systemz, originally advertised in the cybercrime underground as far back as March 2013, was previously documented by BitSight as being deployed as part of cyber attacks targeting distributing PrivateLoader, SmokeLoader, and Amadey. The primary objective of the malware is to turn compromised systems into proxy exit nodes, which are t...

Want to Grow Vulnerability Management into Exposure Management? Start Here!

Dec 05, 2024Attack Surface / Exposure Management
Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
Europol Dismantles Criminal Messaging Service MATRIX in Major Global Takedown

Europol Dismantles Criminal Messaging Service MATRIX in Major Global Takedown

Dec 04, 2024 Encryption / Cybercrime
Europol on Tuesday announced the takedown of an invite-only encrypted messaging service called MATRIX that's created by criminals for criminal purposes. The joint operation, conducted by French and Dutch authorities under the moniker Passionflower , comes in the aftermath of an investigation that was launched in 2021 after the messaging service was discovered on the phone of a criminal convicted for the murder of a Dutch journalist Peter R. de Vries . This allowed authorities to intercept messages being sent via the service for a period of three months, amassing a total of more than 2.3 million messages in 33 languages. The messages, Europol said, are associated with serious crimes such as international drug trafficking, arms trafficking, and money laundering.  It's worth noting at this stage that MATRIX is different from the open-source, decentralized messaging app of the same name ("matrix[.]org"). Also known by other names such as Mactrix, Totalsec, X-quantum...

Matrix Botnet Exploits IoT Devices in Widespread DDoS Botnet Campaign

Matrix Botnet Exploits IoT Devices in Widespread DDoS Botnet Campaign

Nov 27, 2024 IoT Security / Network Security
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 ...

Ngioweb Botnet Fuels NSOCKS Residential Proxy Network Exploiting IoT Devices

Nov 19, 2024 Botnet / IoT Security
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...

German Police Disrupt DDoS-for-Hire Platform dstat[.]cc; Suspects Arrested

Nov 04, 2024 DDoS Attack / Cybercrime
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 ...

U.S. Charges Two Sudanese Brothers for Record 35,000 DDoS Attacks

Oct 17, 2024 Cyber Crime / Hacktivism
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...

New Gorilla Botnet Launches Over 300,000 DDoS Attacks Across 100 Countries

Oct 07, 2024 IoT Security / Botnet
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 Thwarts Largest-Ever 3.8 Tbps DDoS Attack Targeting Global Sectors

Oct 04, 2024 DDoS Attack / Botnet
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...
New Linux Malware Campaign Exploits Oracle Weblogic to Mine Cryptocurrency

New Linux Malware Campaign Exploits Oracle Weblogic to Mine Cryptocurrency

Sep 13, 2024 Enterprise Security / Vulnerability
Cybersecurity researchers have uncovered a new malware campaign targeting Linux environments to conduct illicit cryptocurrency mining and deliver botnet malware. The activity, which specifically singles out the Oracle Weblogic server, is designed to deliver a malware strain dubbed Hadooken , according to cloud security firm Aqua. "When Hadooken is executed, it drops a Tsunami malware and deploys a crypto miner," security researcher Assaf Moran said . The attack chains exploit known security vulnerabilities and misconfigurations, such as weak credentials, to obtain an initial foothold and execute arbitrary code on susceptible instances. This is accomplished by launching two nearly-identical payloads, one written in Python and the other, a shell script, both of which are responsible for retrieving the Hadooken malware from a remote server (" 89.185.85[.]102 " or " 185.174.136[.]204 "). "In addition, the shell script version attempts to iterate ov...

Monitoring evolving DDoS trends is essential for anticipating threats and adapting defensive strategies. The comprehensive Gcore Radar Report for the first half of 2024 provides detailed insights into DDoS attack data, showcasing changes in attack patterns and the broader landscape of cyber threats. Here, we share a selection of findings from the full report. Key Takeaways The number of DDoS attacks in H1 2024 has increased by 46% compared to the same period last year, reaching 445K in Q2 2024. Compared to data for the previous six months (Q3–4 2023), it increased by 34%. Peak attack power increased slightly: The most powerful attack in H1 2024 reached 1.7 Tbps. By comparison, in 2023, it was 1.6 Tbps. Although there has only been an increase of 0.1 Tbps in a year, this still indicates a gain in power that poses a significant danger. To put this into perspective, a terabit per second (Tbps) represents a massive amount of data flooding a network, equivalent to over 212,000 high-d...
Hackers Exploit Misconfigured Jupyter Notebooks with Repurposed Minecraft DDoS Tool

Hackers Exploit Misconfigured Jupyter Notebooks with Repurposed Minecraft DDoS Tool

Aug 03, 2024 DDoS Attack / Server Security
Cybersecurity researchers have disclosed details of a new distributed denial-of-service (DDoS) attack campaign targeting misconfigured Jupyter Notebooks. The activity, codenamed Panamorfi by cloud security firm Aqua, utilizes a Java-based tool called mineping to launch a TCP flood DDoS attack. Mineping is a DDoS package designed for Minecraft game servers. Attack chains entail the exploitation of internet-exposed Jupyter Notebook instances to run wget commands for fetching a ZIP archive hosted on a file-sharing site called Filebin. The ZIP file contains two Java archive (JAR) files, conn.jar and mineping.jar, with the former used to establish connections to a Discord channel and trigger the execution of the mineping.jar package. "This attack aims to consume the resources of the target server by sending a large number of TCP connection requests," Aqua researcher Assaf Morag said . "The results are written to the Discord channel." The attack campaign has bee...
OVHcloud Hit with Record 840 Million PPS DDoS Attack Using MikroTik Routers

OVHcloud Hit with Record 840 Million PPS DDoS Attack Using MikroTik Routers

Jul 05, 2024 Network Security / DDoS Attack
French cloud computing firm OVHcloud said it mitigated a record-breaking distributed denial-of-service (DDoS) attack in April 2024 that reached a packet rate of 840 million packets per second (Mpps). This is just above the previous record of 809 million Mpps reported by Akamai as targeting a large European bank in June 2020. The 840 Mpps DDoS attack is said to have been a combination of a TCP ACK flood that originated from 5,000 source IPs and a DNS reflection attack leveraging about 15,000 DNS servers to amplify the traffic. "While the attack was distributed worldwide, 2/3 of total packets entered from only four [points of presence], all located in the U.S. with 3 of them being on the west coast," OVHcloud noted . "This highlights the capability of the adversary to send a huge packet rate through only a few peerings, which can prove very problematic." The company said it has observed a significant uptick in DDoS attacks in terms of both frequency and intensi...
