FreakOut! Ongoing Botnet Attack Exploiting Recent Linux Vulnerabilities
January 19, 2021Ravie Lakshmanan
An ongoing malware campaign has been found exploiting recently disclosed vulnerabilities in network-attached storage (NAS) devices running on Linux systems to co-opt the machines into an  IRC botnet  for launching distributed denial-of-service (DDoS) attacks and mining Monero cryptocurrency. The attacks deploy a new  malware variant called " FreakOut " by leveraging critical flaws fixed in Laminas Project (formerly Zend Framework) and Liferay Portal as well as an unpatched security weakness in TerraMaster, according to Check Point Research's new analysis published today and shared with The Hacker News. Attributing the malware to be the work of a long-time cybercrime hacker — who goes by the aliases Fl0urite and Freak on HackForums and Pastebin at least since 2015 — the researchers said the flaws —  CVE-2020-28188 ,  CVE-2021-3007 , and  CVE-2020-7961  — were weaponized to inject and execute malicious commands in the server. Regardless of the vulnerabilities exploit

Suspected 'Big Bitcoin Heist' Mastermind Fled to Sweden On Icelandic PM's Plane
April 18, 2018Swati Khandelwal
Remember the " Big bitcoin heist " we reported last month when a group of thieves stole around 600 powerful bitcoin mining devices from Icelandic data centers? Icelandic Police had arrested 11 suspects as part of the investigation, one of which has escaped from prison and fled to Sweden on a passenger plane reportedly also carrying the Icelandic prime minister Katrin Jakobsdottir. Sindri Thor Stefansson , who is suspected of masterminding the whole theft of almost $2 million worth of cryptocurrency-mining equipment, traveled under a passport of someone else but identified through surveillance footage. Stefansson had recently been transferred to a low-security Sogn prison, located in rural southern Iceland (just 59 miles away from Iceland's international airport in Keflavik), from where he escaped through a window early Tuesday and boarded the flight to Sweden. Prime minister Jakobsdottir was on her way to Sweden to take part in India-Nordic Summit and meet Indi

Bitcoin is breaking every record—after gaining 20% jump last week, Bitcoin price just crossed the $14,800 mark in less than 24 hours—and there can be no better reason for hackers to put all of their efforts to steal skyrocketing cryptocurrency. NiceHash, the largest Bitcoin mining marketplace, has been hacked, which resulted in the theft of more than 4,700 Bitcoins worth over $57 million (at the time of breach). And guess what? You'll be surprised to know that the stolen BTC now worth over $70 million—in less than 24 hours. Founded in 2014, NiceHash is a cloud-based crypto-mining marketplace that connects people from all over the world to rent out their spare computing power to other in order to create new coins. On Wednesday, several NiceHash users reported that their BTC wallets had been emptied, which was later confirmed by NiceHash after its service went offline claiming to be undergoing maintenance. At the time of writing, the NiceHash service is still offline wi

Cryptocurrency Mining Scripts Now Run Even After You Close Your Browser

Cryptocurrency Mining Scripts Now Run Even After You Close Your Browser
November 30, 2017Swati Khandelwal
Some websites have found using a simple yet effective technique to keep their cryptocurrency mining javascript secretly running in the background even when you close your web browser. Due to the recent surge in cryptocurrency prices, hackers and even legitimate website administrators are increasingly using JavaScript-based cryptocurrency miners to monetize by levying the CPU power of their visitor's PC to mine Bitcoin or other cryptocurrencies. After the world's most popular torrent download website, The Pirate Bay , caught secretly  using Coinhive , a browser-based cryptocurrency miner service, on its site last month, thousands of other websites also started using the service as an alternative monetization model to banner ads. However, websites using such crypto-miner services can mine cryptocurrencies as long as you're on their site. Once you close the browser window, they lost access to your processor and associated resources, which eventually stops mining. Un

The Pirate Bay Caught Running Browser-Based Cryptocurrency Miner
September 19, 2017Unknown
The world's popular torrent download website, The Pirate Bay , has again been in a new controversy—this time over secretly planting an in-browser cryptocurrency miner on its website that utilizes its visitors' CPU processing power in order to mine digital currencies. The Pirate Bay is the most popular and most visited file-sharing website predominantly used to share copyrighted material free of charge. The site has usually been in the news for copyright infringement by movie studios, music producers and software creators. The Pirate Bay has recently been caught generating revenue by secretly utilizing CPU power of its millions of visitors to mine a Bitcoin alternative called Monero without their knowledge. The modern Internet depends on advertising revenue to survive, which apparently sometimes spoils users' experience. But The Pirate Bay is trying to choose a different approach. Visitors to the Pirate Bay recently discovered a JavaScript-based cryptocurrency mine

DDoSCoin — New Crypto-Currency Pays Users for Participating in DDoS Attacks

DDoSCoin — New Crypto-Currency Pays Users for Participating in DDoS Attacks
August 14, 2016Swati Khandelwal
It's 2016, and now, you can earn some dollars by contributing into well-organized DDoS attack scheme. Do you know while mining Bitcoins you are actually contributing a significant computational power to keep the Bitcoin network running? In Bitcoins, the miners actually build and maintain massive public ledger containing a record of every Bitcoin transaction in history. When one user tries to send Bitcoins to another user, the miners validate the transfer by checking the ledger to make sure the sender is not transferring money he/she does not have, adding the transaction to the ledger and then finally sealing it behind layers and layers of computational work to protect that ledger from getting compromised or hacked. So for this, miners are rewarded with Bitcoins. So, basically, you are contributing the massive amount of computing power that keeps the Bitcoin transactions running and makes you earn some cryptocurrency in return as an incentive. However, Bitcoin has long be
