A new distributed denial-of-service (DDoS) botnet known as Kimwolf has enlisted a massive army of no less than 1.8 million infected devices comprising Android-based TVs, set-top boxes, and tablets, and may be associated with another botnet known as AISURU , according to findings from QiAnXin XLab. "Kimwolf is a botnet compiled using the NDK [Native Development Kit]," the company said in a report published today. "In addition to typical DDoS attack capabilities, it integrates proxy forwarding, reverse shell, and file management functions." The hyper-scale botnet is estimated to have issued 1.7 billion DDoS attack commands within a three-day period between November 19 and 22, 2025, around the same time one of its command-and-control (C2) domains – 14emeliaterracewestroxburyma02132[.]su – came first in Cloudflare's list of top 100 domains, briefly even surpassing Google. Kimwolf's primary infection targets are TV boxes deployed in residential network en...

Cybersecurity researchers are calling attention to a series of cyber attacks targeting financial organizations across Africa since at least July 2023 using a mix of open-source and publicly available tools to maintain access. Palo Alto Networks Unit 42 is tracking the activity under the moniker CL-CRI-1014 , where "CL" refers to "cluster" and "CRI" stands for "criminal motivation." It's suspected that the end goal of the attacks is to obtain initial access and then sell it to other criminal actors on underground forums, making the threat actor an initial access broker (IAB). "The threat actor copies signatures from legitimate applications to forge file signatures , to disguise their toolset and mask their malicious activities," researchers Tom Fakterman and Guy Levi said . "Threat actors often spoof legitimate products for malicious purposes." The attacks are characterized by the deployment of tools like PoshC2 fo...

Meta's WhatsApp has rolled out updates to its proxy feature, allowing more flexibility in the kind of content that can be shared in conversations. This includes the ability to send and receive images, voice notes, files, stickers and GIFs, WhatsApp told The Hacker News. The new features were  first reported  by BBC Persian. Some of the other improvements include streamlined steps to simplify the setup process as well as the introduction of shareable links to "share functioning/valid proxy addresses to their contacts for easy and automatic installation." Support for  proxy servers  was officially launched by the messaging service  earlier this January , thereby helping users circumvent government-imposed censorship and internet shutdowns and obtain indirect access to WhatsApp. The company has also made available a  reference implementation  for setting up a proxy server with ports 80, 443, or 5222 available and a domain name that points to the serv...

A previously undocumented backdoor has been observed targeting Linux systems with the goal of corralling the machines into a botnet and acting as a conduit for downloading and installing rootkits. Qihoo 360's Netlab security team called it  B1txor20  "based on its propagation using the file name 'b1t,' the XOR encryption algorithm, and the RC4 algorithm key length of 20 bytes." First observed propagating through the  Log4j vulnerability  on February 9, 2022, the malware leverages a technique called DNS tunneling to build communication channels with command-and-control (C2) servers by encoding data in DNS queries and responses. B1txor20, while also buggy in some ways, currently supports the ability to obtain a shell, execute arbitrary commands, install a rootkit, open a  SOCKS5 proxy , and functions to upload sensitive information back to the C2 server. Once a machine is successfully compromised, the malware utilizes the DNS tunnel to retrieve and execute ...

A widely used NPM package called ' Pac-Resolver ' for the JavaScript programming language has been remediated with a fix for a high-severity remote code execution vulnerability that could be abused to run malicious code inside Node.js applications whenever HTTP requests are sent.  The flaw, tracked as  CVE-2021-23406 , has a severity rating of 8.1 on the CVSS vulnerability scoring system and affects Pac-Resolver versions before 5.0.0. A Proxy Auto-Configuration ( PAC ) file is a JavaScript function that determines whether web browser requests should be routed directly to the destination or forwarded to a web proxy server for a given hostname. PAC files are how proxy rules are distributed in enterprise environments. "This package is used for PAC file support in  Pac-Proxy-Agent , which is used in turn in  Proxy-Agent , which then used all over the place as the standard go-to package for HTTP proxy auto-detection and configuration in Node.js," Tim Perry  said...

The world of mobile search is about to get a bit more anonymous. Thanks to the fears over government surveillance and corporate tracking, Anonymous Search Engine DuckDuckGo continues to break its own search records. DuckDuckGo Search & Stories - Android app deliver the same functionality as traditional services such as Google but with the added promise that your IP address and identity will not be recorded.  In June, Anonymous search engine  DuckDuckGo  had launched its app for  iOS  and Android and during recent update, DuckDuckGo's application for Android also integrated the Tor support. " Privacy is perhaps more important on mobile than on the web, and we haven't had many private alternatives ," DuckDuckGo founder Gabriel Weinberg said. To enable Tor with DuckDuckGo android app, user need to Check " Enable Tor " from setting. It will prompt the user to install about application to anonymize the Mobile data c...

No matter how much effort an ISP puts in or the government does, censorship always gets a backdoor . One of the biggest Controversial File Sharing site ' The Pirate Bay ' is censored in various capacities in some countries around the world, but Pirate Bay is celebrating its 10th birthday in Stockholm sponsored by an energy drinks maker. On their 10th anniversary the site is releasing its " Pirate Browser ," a custom Firefox browser that skirts Internet censorship and lets you access the Pirate Bay from anywhere.  However, Its founders recently served jail time for their activities, with one of the founders going back to prison in an unrelated Swedish hacking case. PirateBrowser is meant to focus more on unrestricted access to the Internet than it is about being able to download new episode of Breaking Bad without paying for them, but one tends to be a function of the other. According to the Pirate Browser website, It's a customized Firefox 23 and inclu...
