The decentralized social network Mastodon has disclosed a critical security flaw that enables malicious actors to impersonate and take over any account. "Due to insufficient origin validation in all Mastodon, attackers can impersonate and take over any remote account," the maintainers said in a terse advisory. The vulnerability, tracked as  CVE-2024-23832 , has a severity rating of 9.4 out of a maximum of 10. Security researcher  arcanicanis  has been credited with discovering and reporting it. It has been described as an "origin validation error" ( CWE-346 ), which can typically allow an attacker to "access any functionality that is inadvertently accessible to the source." Every Mastodon version prior to 3.5.17 is vulnerable, as are 4.0.x versions before 4.0.13, 4.1.x versions before 4.1.13, and 4.2.x versions before 4.2.5. Mastodon said it's withholding additional technical specifics about the flaw until February 15, 2024, to give  admins  ampl...

A number of phishing campaigns are leveraging the decentralized InterPlanetary Filesystem (IPFS) network to host malware, phishing kit infrastructure, and facilitate other attacks. "Multiple malware families are currently being hosted within IPFS and retrieved during the initial stages of malware attacks," Cisco Talos researcher Edmund Brumaghin said in an analysis shared with The Hacker News. The research mirrors similar findings from Trustwave SpiderLabs in July 2022, which  found  more than 3,000 emails containing IPFS phishing URLs as an attack vector, calling IPFS the new "hotbed" for hosting phishing sites. IPFS as a technology is both resilient to censorship and takedowns, making it a double-edged sword. Underlying it is a peer-to-peer (P2P) network which replicates content across all participating nodes so that even if a file is removed from one machine, requests for the resource can still be served via other systems. This also makes it ripe for abuse...

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...

Just last month, DARPA launched a project dubbed "Improv," inviting hackers to transform simple household appliances into deadly weapons . Now, the Defense Advanced Research Projects Agency is finding someone in the private sector to develop a hacker-proof " secure messaging and transaction platform " for the U.S. military. Darpa wants researchers to create a secure messaging and transaction platform that should be accessible via the web browser or standalone native application. The secure messaging app should " separate the message creation, from the transfer (transport) and reception of the message using a decentralized messaging backbone to allow anyone anywhere the ability to send a secure message or conduct other transactions across multiple channels traceable in a decentralized ledger, " agency's  notice explains. In simple words, DARPA aims to create a secure messaging service that not only implements the standard encryption and se...

Imagine the internet that would offer you to communicate privately with anyone else without censorship, safe from the prying eyes of surveillance authorities…. … Decentralized, Encrypted, Peer-to-Peer Supported and especially a non-IP Address based Internet. Yeah, a New Private Internet that would be harder to get Hacked. This Internet is a dream of all Internet users today and, of course, Kim Dotcom – the Famous Internet entrepreneur who introduced legendary Megaupload and MEGA file sharing services to the World. Kim Dotcom announced plans to start his very own private internet at the beginning of this year and has now revealed more details about MegaNet — a decentralized, non-IP based network that would share data via " Blockchains ," the technology behind Bitcoins. On Thursday, Dotcom remotely addressed a conference in Sydney, Australia, where he explained how MegaNet will utilize the power of mobile phones and laptops to operate. How will M...

The Existing Infrastructure used by Financial institutions like Banks is Archaic, Slow, and Costly, with hardly any innovation in the past three decades. Nine of the World's renowned Banks, including JPMorgan , Royal Bank of Scotland , Goldman Sachs and Barclays , are collaborating with New York-based financial tech firm R3 to create a new framework based on Bitcoin's Blockchain. Yes, they are back in the game yet again, but this time officially! Blockchain — the public and decentralized ledger technology that underpins all Bitcoin transactions has been now recognized as " the future for financial services infrastructure ". The blockchain technology is a way of keeping records by listing the owner's name with all the previous and present transaction the client was involved. It is a public ledger where a list of all the transactions ever executed is maintained. The Banks are planning to develop and implement Blockchain-like Technology where distributed/shared ...

The Famous Internet entrepreneur and former hacker Kim Dotcom , who introduced legendary Megaupload and MEGA file sharing services to the World, has came up with another crazy idea — To start his very own Internet that uses the "blockchain". Just last month, Kim Dotcom, a German millionaire formerly known as Kim Schmitz , launched the public beta of its end-to-end encrypted video and audio chat service called " MegaChat ", which it says gives better protection than alternatives such as Skype and Google Hangouts. Now, his latest series of tweets referred to Kim Dotcom's supposed " MegaNet " which, he believes, would be immune to the global mass surveillance conducted by governments or corporations and would not be based on IP addresses. MegaNet would be a decentralized, non-IP based network in which the blockchain used by Bitcoin will play an " important role ". Decentralizing the Internet means to take the power of the Web...
