Automatic graylisting of unwanted software

Maximum security, minimal effort


As network perimeters become ever more porous, and endpoint security becomes even more critical, companies today are struggling with the problem of unwanted software - whether it's new, unknown, and potentially malicious software, or simply known but non-business applications.

Now, a new approach to endpoint security known as automatic graylisting is enabling IT professionals to regain control over spyware, malware, and other unwanted and unapproved applications with real-time, network-wide visibility and control - for maximum security with minimal effort.

The problem of unwanted software

Unwanted software represents a root cause of a wide variety of IT problems that involve not just time, but money. For example, Microsoft estimates that spyware causes one third of system crashesand according to the Business Software Alliance, unlicensed software can result in settlements in excess of $100,000.

Unwanted software includes worms, viruses, spyware, vulnerable applications, unlicensed software, and unsanctioned applications, and it can arrive on corporate networks in many ways. The scope of the problem ranges from mobile users connecting to infected networks to end users unknowingly infesting their office desktops with spyware. As well, end users can knowingly download non-sanctioned applications such as peer-to-peer file-sharing, instant messaging, mp3 applications, and others.

SANS has reported that the number of vulnerabilities in 2005 is going up, not down: "Despite increasing public and corporate awareness about cybersecurity, the number of computer vulnerabilities in the second quarter of 2005 increased 10.8 per cent compared with the first quarter, according to a new survey from the SANS Institute, which develops data and research on information security. In all, SANS discovered 422 new vulnerabilities, up from 381 in the first quarter."

To complicate matters further, spyware producers continue to make the legal case that their software is neither malicious nor illegal. While unwanted software encompasses a variety of applications that have different implications and characteristics, today's solutions typically focus on narrow aspects of the problem. Thus, different tools have evolved to solve a subset of the problem. For example, most current security products attempt to detect only malicious applications of certain types and new malicious software is discovered each day. In fact, Sophos recently identified 1,233 new viruses in September 2005 alone. Unfortunately, this approach has caused a proliferation of agents on systems that increase complexity and administrative effort.

    In brief Thieves operating for the North Korean government made off with almost $400m in digicash last year in a concerted attack to steal and launder as much currency as they could.

    A report from blockchain biz Chainalysis found that attackers were going after investment houses and currency exchanges in a bid to purloin funds and send them back to the Glorious Leader's coffers. They then use mixing software to make masses of micropayments to new wallets, before consolidating them all again into a new account and moving the funds.

    Bitcoin used to be a top target but Ether is now the most stolen currency, say the researchers, accounting for 58 per cent of the funds filched. Bitcoin accounted for just 20 per cent, a fall of more than 50 per cent since 2019 - although part of the reason might be that they are now so valuable people are taking more care with them.

  • Tesla Full Self-Driving videos prompt California's DMV to rethink policy on accidents

    Plus: AI systems can identify different chess players by their moves and more

    In brief California’s Department of Motor Vehicles said it’s “revisiting” its opinion of whether Tesla’s so-called Full Self-Driving feature needs more oversight after a series of videos demonstrate how the technology can be dangerous.

    “Recent software updates, videos showing dangerous use of that technology, open investigations by the National Highway Traffic Safety Administration, and the opinions of other experts in this space,” have made the DMV think twice about Tesla, according to a letter sent to California’s Senator Lena Gonzalez (D-Long Beach), chair of the Senate’s transportation committee, and first reported by the LA Times.

    Tesla isn’t required to report the number of crashes to California’s DMV unlike other self-driving car companies like Waymo or Cruise because it operates at lower levels of autonomy and requires human supervision. But that may change after videos like drivers having to take over to avoid accidentally swerving into pedestrians crossing the road or failing to detect a truck in the middle of the road continue circulating.

  • Alien life on Super-Earth can survive longer than us due to long-lasting protection from cosmic rays

    Laser experiments show their magnetic fields shielding their surfaces from radiation last longer

    Life on Super-Earths may have more time to develop and evolve, thanks to their long-lasting magnetic fields protecting them against harmful cosmic rays, according to new research published in Science.

    Space is a hazardous environment. Streams of charged particles traveling at very close to the speed of light, ejected from stars and distant galaxies, bombard planets. The intense radiation can strip atmospheres and cause oceans on planetary surfaces to dry up over time, leaving them arid and incapable of supporting habitable life. Cosmic rays, however, are deflected away from Earth, however, since it’s shielded by its magnetic field.

    Now, a team of researchers led by the Lawrence Livermore National Laboratory (LLNL) believe that Super-Earths - planets that are more massive than Earth but less than Neptune - may have magnetic fields too. Their defensive bubbles, in fact, are estimated to stay intact for longer than the one around Earth, meaning life on their surfaces will have more time to develop and survive.
