What Is Cryptocurrency – How It Works, History & Bitcoin Alternatives Cryptocurrency History Bitcoin Alternatives Cryptocurrencies, or virtual currencies, are digital means of exchange created and used by private individuals or groups. Because most cryptocurrencies aren’t regulated by national governments, they’re considered alternative currencies – mediums of financial exchange that exist outside the bounds of state monetary policy. Bitcoin is the preeminent cryptocurrency and first to be used widely. However, hundreds of cryptocurrencies exist, and more spring into being every month. What Is Cryptocurrency? Cryptocurrencies use cryptographic protocols, or extremely complex code systems that encrypt sensitive data transfers, to secure their units of exchange. Cryptocurrency developers build these protocols on advanced mathematics and computer engineering principles that render them virtually impossible to break, and thus to duplicate or counterfeit the protected currencies.

IMSI Catchers What is an IMSI catcher? An IMSI catcher is an intrusive piece of technology that can be used to locate and track all mobile phones that are switched on in a certain area.  An IMSI catcher does this by ‘pretending’ to be a mobile phone tower - tricking your phone into connecting to the IMSI-catcher, and then revealing your personal details without your knowledge. IMSI catchers are indiscriminate surveillance tools that could be used to  track who attends a political demonstration or a public event like a football match. They can even be used to monitor your calls and edit your messages – and you wouldn’t even know it was happening. Who is using IMSI catchers? The police  “neither confirm nor deny”  that they use IMSI catchers. This means that the police are refusing to explain to the public how they could use these invasive devices to secretly access data from our mobile phones. However, documents obtained by  Bristol Cable...

International Mobile Subscriber Identity (IMSI) Definition - What does  International Mobile Subscriber Identity (IMSI)  mean? An international mobile subscriber identity (IMSI) is a unique number, usually fifteen digits, associated with Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) network mobile phone users. The IMSI is a unique number identifying a GSM subscriber. This number has two parts. The initial part is comprised of six digits in the North American standard and five digits in the European standard. It identifies the GSM network operator in a specific country with whom the subscriber holds an account. The second part is allocated by the network operator to uniquely identify the subscriber. The IMSI is stored in the Subscriber Identity Module (SIM) inside the phone and is sent by the phone to the appropriate network. The IMSI is used to acquire the details of the mobile in the Home Location Re...

The best deep web search engines     The deep web is exactly what it sounds like: the underground internet, the portion that’s not indexed by traditional search engines like Google or Bing—and it’s much bigger than you might realize. In fact, major sites like Facebook, Wikipedia, and everything else you find through a search engine make up less than 1 percent of the internet. The most secretive section in the deep web is known as the dark net, and you’ll need to download Tor to access it (here’s more on that process). Many people search the deep web to find drugs, illegal porn, or stolen credit cards. But deep web search engines also provide a lot of educational archives, hidden articles from academic journals, and intel on news around the world. Finding all the untapped information is not as difficult as it might seem at first glance. With these user-friendly, deep web search engines, hidden information is just a few clicks aw...

Operator of VirusTotal Like Malware-Scanning Service Jailed for 14 Years A Latvian hacker behind the development and operation of counter antivirus service "Scan4You" has finally been sentenced to 14 years in prison. 37-year-old Ruslans Bondars, described as a Latvian "non-citizen" or "citizen of the former USSR who had been residing in Riga, Latvia," was found guilty on May 16 in federal court in Alexandria, during which a co-conspirator revealed he had worked with Russian law enforcement. Bondars created and ran Scan4you—a VirusTotal like online multi-engine antivirus scanning service that allowed hackers to run their code by several popular antiviruses to determine if their computer virus or malware would be flagged during routine security scans before launching them into a real-world malware campaign. While legal scanning services share data about uploaded files with the antivirus firms, Scan4you instead informed its user...

Researcher Discloses New Zero-Day Affecting All Versions of Windows A security researcher has publicly disclosed an unpatched zero-day vulnerability in all supported versions of Microsoft Windows operating system (including server editions) after the company failed to patch a responsibly disclosed bug within the 120-days deadline. Discovered by  Lucas Leong  of the Trend Micro Security Research team, the zero-day vulnerability resides in Microsoft Jet Database Engine that could allow an attacker to remotely execute malicious code on any vulnerable Windows computer. The Microsoft JET Database Engine, or simply JET (Joint Engine Technology), is a database engine integrated within several Microsoft products, including Microsoft Access and Visual Basic. According to the an  advisory  released by Zero Day Initiative (ZDI), the vulnerability is due to a problem with the management of indexes in the Jet database engine that, if exploited successful...
