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 successfully, can cause an ou

What to do if your Android device falls victim to a ransomware attack? All of a sudden, you find yourself staring at a locked screen with no ability to use your phone or access any of its contents. Your first impulse may be to pay the ransom and make the problem go away.  Don’t do it!  For one thing, there’s no guarantee that paying the ransom will actually make the problem go away. You’re relying on the integrity of criminals, after all. Also, if they see that you’re willing to pay, then you’re putting an even bigger target on your back for future attacks. As long as ransomware attacks continue to work, cybercriminals will continue to use them. There are two ways to deal with a traditional ransomware attack in which you’re locked out of your Android device. First, you should try to  reboot the device  in Safe Mode,  revoke Device Administrator privileges  (if you granted them to the app)  and then  delete the app, program, or plug-in  caused the problem. Here are the steps t

TOR Fone p2p secure and anonymous VoIP tool The fundamental right to privacy, guaranteed by the Fifth and Fourteenth Amendments to the U. S. Constitution, protects against unwarranted invasions of privacy by federal or state entities, or arms thereof. Internet telephony  is now an important part of people communications and should be protected from intruders, collecting information about you. I had an idea to use the old PGPFone designed by Philip Zimmermann for these purposes by adding the possibility to use The Onion Router anonymizer to ensure anonymity of callers. I did some tests to adopt VoIP transport to TOR tunnels and eventually made acceptable alpha release.  Now the beta version is available which includes an improved cryptography, new voice codecs and lot of other new features. As a result, the  TORFone  was designed to communicate voice via Internet (make phone calls to the addressee) similarly to Skype but with the following difference

Top 100 VOIP providers Our Top 100 is ranked based on user reviews, market segment, provider size, and price. We tend to rank business VoIP providers ahead of residential and wholesale providers and providers with more reviews higher than providers with fewer reviews. It’s a lot more difficult to get 100+ reviews (even if they’re mostly negative) than it is to get 2 5-star reviews. If you do not see a specific provider listed here, please check our VoIP graveyard.
