  • In an experiment that took 13 years to perfect1, the researchers have found that these electrons tend to destroy certain organic molecules slightly more often than they destroy their mirror images.
  • The weak nuclear force, which is involved in nuclear decay, is the only force of nature known to have a handedness preference: electrons created in the subatomic process known as β decay are always 'left-handed'. This means that their spin — a quantum property analogous to the magnetization of a bar magnet — is always opposite in direction to the electron's motion.
  • In all cases the asymmetry was tiny, but consistent, like flipping a not-quite-fair coin. “The scale of the asymmetry is as though we flip 20,000 coins again and again, and on average, 10,003 of them land on heads while 9,997 land on tails,” says Dreiling.

  • Since some time in the second half of 2014, a different state-sponsored group had been casing their corporate network using malware derived from Stuxnet, the highly sophisticated computer worm reportedly created by the US and Israel to sabotage Iran’s nuclear program.
  • the malware was more advanced than the malicious programs developed by the NSA-tied Equation Group that Kaspersky just exposed. More intriguing still, Kaspersky antivirus products showed the same malware has infected one or more venues that hosted recent diplomatic negotiations the US and five other countries have convened with Iran over its nuclear program.
  • We see this battle or arms race emerging and now it involves some kind of confrontation between the security industry and nation-state sponsored spies

  • Kaspersky officials first became suspicious their network might be infected in the weeks following February's Security Analyst Summit, where company researchers exposed a state-sponsored hacking operation that had ties to some of the developers of Stuxnet. Kaspersky dubbed the highly sophisticated group behind the 14-year campaign Equation Group. Now back in Moscow, a company engineer was testing a software prototype for detecting so-called advanced persistent threats (APTs), the type of well-organized and highly sophisticated attack campaigns launched by well-funded hacking groups. Strangely enough, the developer's computer itself was having unusual interactions with the Kaspersky network. The new APT technology under development, it seemed, was one of several things of interest to the Duqu attackers penetrating the Kaspersky fortress. "For the developer it was important to find out why" his PC was acting oddly, Kamluk said. "Of course, he did not consider that machine could be infected by real malware. We eventually found an alien module that should not be there that tried to mask behind legitimate looking modules from Microsoft. That was the point of discovery."
  • What they found was a vastly overhauled malware operation that made huge leaps in stealth, operational security, and software design. The Duqu actors also grew much more ambitious, infecting an estimated 100 or so targets, about twice as many as were hit by the 2011 version.
  • So the Duqu 2.0 attackers pulled an audacious feat that Kaspersky researchers had never seen before. Virtually all of the malware resided solely in the memory of the compromised computers or servers. When one of them was restarted, the infection would be purged, but as the rebooted machine reconnected to the network, it would be infected all over again by another compromised computer in the corporate network. The secret lynchpin making this untraceable reinfection scheme possible was the Windows vulnerability Microsoft patched only Tuesday, which has been designated

  • Researchers have uncovered a malware campaign that gave attackers the ability to sabotage the operations of energy grid owners, electricity generation firms, petroleum pipelines, and industrial equipment providers.
  • the hacking group managed to install one of two remote access trojans (RATs) on computers belonging to energy companies located in the US and at least six European countries, according to a

  • "This campaign follows in the footsteps of Stuxnet, which was the first known major malware campaign to target ICS systems," the Symantec report stated. "While Stuxnet was narrowly targeted at the Iranian nuclear program and had sabotage as its primary goal, Dragonfly appears to have a much broader focus with espionage and persistent access as its current objective with sabotage as an optional capability if required."

  • "The Dragonfly group is technically adept and able to think strategically," the Symantec report stated. "Given the size of some of its targets, the group found a 'soft underbelly' by compromising their suppliers, which are invariably smaller, less protected companies."
