Cyber criminals targeting another cryptocurrency 'Primecoin' with malicious miners

Cyber criminals targeting another cryptocurrency 'Primecoin' with malicious miners

January 16, 2014Mohit Kumar
Like Bitcoin, There are numerous other cryptocurrency similar in nature, including  MasterCoin , ProtoShares, Litecoin, Peercoin, BitBar and many more. One of them is  Primecoin  (sign: Ψ; code: XPM),  a peer-to-peer open source cryptocurrency that implements a scientific computing proof-of-work system. Unlike Bitcoin or other virtual currencies, only Primecoin provides a proof of work that has intrinsic value. It generates a special form of prime number chains, known as ‘ Cunningham chains & bi-twin chains ’ and has a real world importance in mathematical research. Worldwide famous RSA Encryption basically uses two prime numbers for generating a RSA key pair. If you are able to factorize the public key and find these prime numbers, you will then be able to find the private key. Thus, the whole Security of RSA encryption is based on the length of prime numbers. So, Primecoin plays a great role for crypto researchers to get large... and a very large number of Primes. Like
How Hackers Cash Out Thousands of Bitcoins Received in Ransomware Attacks

How Hackers Cash Out Thousands of Bitcoins Received in Ransomware Attacks

July 28, 2017Swati Khandelwal
Digital currencies have emerged as a favourite tool for hackers and cyber criminals, as digital currency transactions are nearly anonymous, allowing cyber criminals to use it in underground markets for illegal trading, and to receive thousands of dollars in ransomware attacks— WannaCry , Petya , LeakerLocker , Locky and Cerber to name a few. Also, every other day we hear about some incidents of hacking of crypto currency exchange or digital wallets, in which hackers stole millions of dollars in Bitcoin or Ethereum. The latest back-to-back series of thefts of Ethereum —one of the most popular and increasingly valuable cryptocurrencies—in which around half a billion dollars in total were stolen is the recent example of how much hackers are after crypto currencies. It's obvious that after ripping off hundreds of thousands of cryptocurrencies from exchanges, wallets and ransomware victims, cyber criminals would not hold them in just digital form—the next step is to cash the

Cybercriminals using hijacked Cloud hosting accounts for targeted attacks

June 14, 2013Anonymous
US Cloud hosting providers are constantly targeted by cyber crime according the revelations of two malware researchers Mary Landesman, a senior security researcher at Cisco Systems, and Dave Monnier security expert at Team Cymru explained during the 2013 Gartner Security and Risk Management Summit. The hackers are exploiting with a meaningful increase these architecture to organize financially motivated attacks. Landesman and Monnier explained in two distinct sessions that cyber criminals are exploiting US cloud hosting providers to deploy Command and Control servers for their malicious activities despite the great effort in monitoring activities operated by hosting cloud providers. US is one of privileged countries to host malicious architecture due high availability of its infrastructures and cyber criminals know it. " You can move your command and control servers to Kazakhstan, but that's not a very good business decision," "The U.S. has re

New Delhi:   With the growing diversity of operating systems among companies, and the increasing use of mobile devices, cyber criminals will put a new spin on social engineering by 'malware campaign' under which they will bombard recipients with email that drop virus downloaders.       According to an internet security software and service provider Trend Micro study on Threat Predictions for 2011, threat researchers have found that more than 80 per cent of the top malware use the web to arrive on users' systems and every second, 3.5 new threats are released by cyber criminals.       During current year, proof of concept attacks against cloud infrastructure and virtualised systems will emerge. Diversity of operating systems at the endpoints forces the cyber criminals to focus more on critical cloud services and server infrastructures. Further, the report noted that mid-sized companies will be targeted in cyber espionage. The growth of targeted and localised attacks will con

Pre-Play Vulnerability Allows Chip-and-PIN Payment Card Cloning

May 20, 2014Mohit Kumar
In March this year, we reported that the major card distributor companies, VISA and Mastercard are migrating to EMV chip cards , also known as PIN-and-Chip cards. Unlike traditional magnetic stripe payment cards, EMV chip cards generates a unique code for every transaction, making it nearly* impossible for criminals to use the card for counterfeit fraud. But Nothing is perfectly secure, even not the PIN-and-Chip based payment cards. All anti-cloning theories were already proven wrong, when a group of researchers found a way to hack the Credit and Debit cards based on the latest Chip-and-Pin technology. Back in 2012, we reported about a research paper entitled “ Chip and Skim: cloning EMV cards with the pre-play attack ” published ( old paper ) by team of researchers from the University of Cambridge, UK, who demonstrated that Chip and PIN payment card systems are also vulnerable to Card Cloning. The same team of researchers presented their EVM related research last Mond

The difference between cyber crime, cyber espionage and cyber war is a matter of a few keystrokes. They use the same techniques. These were the words of Richard Clarke, chairman of Good Harbor Consulting , during his keynote at the RSA Europe 2010 conference, being held in London this week. Giving background, he said cyber crime is not a theory, it goes on every day. “Just two weeks ago, there were arrests of a cyber cartel in the US. However, those arrested were students, acting as mules. To be a mule all they have to do is open a bank account and allow money to flow in and out of it. They are on the lowest level of the cyber crime structure.” This is typically the situation in cyber crime, explained Clarke. “These cartels are often based in Moldova, Estonia, Belarus or Russia. Once there has been an investigation, often long and complicated, using warrants to search computers and servers , crimes are traced back to these countries. However, when the investigators

Beware! Cyber Criminals Spreading Click Fraud Trojan for Making Money

May 11, 2014Swati Khandelwal
Before Ransomware, Click fraud was one of the popular and efficient ways for cybercriminals to make money and with the explosive growth in the size of the online threats it is still making its way on the Internet. “ Click-Fraud ” is the practice of deceptively clicking on search ads with the intention of either increasing third-party website revenues or exhausting an advertiser’s budget. Besides the search results, we all have seen advertisements placed in the search engine’s WebPage. If the visitor clicks the Ad, the advertiser has to pay a fee to the search engine. A problem that has arisen with pay-per-click is results in Click-Fraud. The term “ fraud ” is used because in either case, the advertiser is paying for a click without receiving any true value. Of course, the number of clicks has to be large enough in order to gain a considerable amount of money, and in order to do that an attacker can use an automated script or malicious program to simulate multiple clicks b

MUMBAI: Cyber experts say there should be proper guidelines when the court grants bail to those arrested under the Information Technology (IT) Act and fast-track courts for cyber-related cases will help proper convictions. Procedures currently followed to grant bail in cyber cases are similar to those under the Indian Penal Code. "Most of the accused are techsavvy and know the loopholes in the legal system very well," acyber expert said. Despite efforts by the cops, Rizwan Alsulkar managed to file a bail plea and will be out soon. "The time granted by the court to investigate the case was very less. This is not the first time where an accused caught under the IT Act has gone scot-free . In tech-related cases, the cops should get proper time to collect evidence ," a police official said. He added a person can be sentenced to 2-3 years under the IT Act. "However, conviction rate is very poor across the country, hardly going above 10% in the last 10 years."
