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...

Hong Kong-based Bitcoin exchange 'Bitfinex' that lost around $72 Million worth of its customers' Bitcoins last week is now offering a reward of $3.5 Million to anyone who can provide information that leads to the recovery of the stolen Bitcoins. Bitfinex revealed on August 2 that the cryptocurrency exchange had suffered a major security breach, which resulted in the loss of nearly 120,000 BTC. The hack led to a 36 percent loss for each Bitfinex customer, who will be issued tokens to be redeemed as the company is able to reimburse the losses. Now, the exchange is willing to offer 5% of the lost funds ( nearly 6,000 BTC ) as a reward for the recovery of the stolen bitcoins. The news came after a Reddit user, using alias someguy916, inquired about a reward Bitfinex would be willing to offer for the stolen bitcoins. In response to the question, Bitfinex community director Zane Tackett stated that a bounty would be awarded to anyone who has information that would hel...

The hacker, who recently claimed responsibility for the high-profile hack of Democratic National Committee (DNC), has now taken credit for hacking into the Democratic Congressional Campaign Committee (DCCC) as well. To prove his claims, the hacker, going by the moniker Guccifer 2.0, dumped on Friday night a massive amount of personal information belonging to nearly 200 Democratic House members onto his blog . The notorious hacker published several documents that include cell phone numbers, home addresses, official and personal e-mail addresses, names of staffers, and other personal information for the entire roster of Democratic representatives. The data dump also includes several memos from House Minority Leader Nancy Pelosi's personal computer, detailing fundraisers and campaign overviews. "As you see the US presidential elections are becoming a farce, a big political performance where the voters are far from playing the leading role," the hacker wrote in a ...

Air-gapped computers that are isolated from the Internet and other computers are long considered to be the most secure and safest place for storing data in critical infrastructures such as industrial control systems, financial institutions, and classified military networks. However, these systems have sometimes been targeted in the past, which proves that these isolated systems are not completely secure. Previous techniques of hacking air gap computers include: AirHopper that turns a computer's video card into an FM transmitter to capture keystrokes; BitWhisper that relies on heat exchange between two computer systems to stealthily siphon passwords or security keys; Hacking air-gapped computer using a basic low-end mobile phone with GSM network; and Stealing the secret cryptographic key from an air-gapped computer placed in another room using a Side-Channel Attack. Now, researchers have devised a new method to steal data from an infected computer even if it has no...

In Brief Some 100 Million cars made by Volkswagen are vulnerable to a key cloning attack that could allow thieves to unlock the doors of most popular cars remotely through a wireless signal, according to new research. Next time when you leave your car in a parking lot, make sure you don't leave your valuables in it, especially if it's a Volkswagen. What's more worrisome? The new attack applies to practically every car Volkswagen has sold since 1995. There are two distinct vulnerabilities present in almost every car sold by Volkswagen group after 1995, including models from Audi, Skoda, Fiat, Citroen, Ford and Peugeot. Computer scientists from the University of Birmingham and the German engineering firm Kasper & Oswald plan to present their research [ PDF ] later this week at the Usenix security conference in Austin, Texas. Attack 1 — Using Arduino-based RF Transceiver (Cost $40) The first attack can be carried out using a cheap radio device that can...
