Microsoft Goes Quantum Computing

Comments Off on Microsoft Goes Quantum Computing

Software giant Microsoft is focusing a lot of its R&D money on quantum computing.

Peter Lee, the corporate vice president of Microsoft Research said that Quantum computing is “stupendously exciting right now.”

Apparently it is Microsoft Research’s largest area of investment and Lee is pretty certain it is on the verge of some major scientific achievements.

“There’s just hope and optimism those scientific achievements will lead to practical outcomes. It’s hard to know when and where,” Lee said.

This is the first we have heard about Redmond’s quantum ambitions for a while. In 2014 the company revealed its “Station Q” group located on the University of California, Santa Barbara, campus, which has focused on quantum computing since its establishment a decade ago.

We sort of assumed that Microsoft would not get much work done on Quantum states because faced with a choice most cats would rather die in a box rather than listen to Steve Ballmer. But we guess with a more cat friendly CEO it is moving ahead.

Lee said that he has explained quantum computing research to Microsoft chief executive Satya Nadella by comparing it with speech processing. In that field, Microsoft researchers worked “so hard for a decade with no practical improvement,” he said. Then deep learning brought about considerable leaps forward in speech recognition and Microsoft was in on the ground floor.

“With quantum, we’ve made just gigantic advancements making semiconductor interfacing, allowing semiconductor materials to operate as though they were superconducting. What that means is the possibility of semiconductors that can operate at extremely high clock rates with very, very little or no heat dissipation. It’s just really spectacular.”

Comments Off on NSA Software Reengineered

Hackers have found a way to reverse engineer the technology of the United States National Security Agency (NSA) spy gadgets.

Thanks to documents leaked by fugitive former NSA contractor and whistleblower Edward Snowden, the group has built a copycat device able to gather private data from computer systems.

The Advanced Network Technology catalogue, leaked by Snowden, is the Argos book of the NSA showing a range of toys available to agents. One such device known has a “retro reflector” had eluded identification, beyond that it acted as a bug, keylogger and screengrabber.

Michael Ossman and his team from Great Scott Gadgets, a Colorado based hacking group, decided that the best defence against such devices was to create their own to understand what makes them tick.

It transpired that the key technology being used is called software defined radio (SDR), an approach that uses software to generate radio transmissions through signal processing, doing away with a lot of hardware circuitry.

“SDR lets you engineer a radio system of any type you like really quickly so you can research wireless security in any radio format,” Ossmann told New Scientist.

The technique can be used for almost any type of radio signal and therefore the devices are capable of tracking anything, from what you’re listening to through a Bluetooth headset to the binary signals of your internet traffic.

The group, which will demonstrate its work at the Defon hacking conference in Las Vegas, runs a website at NSAplayset.org that is a repository for all of the information it gathered.

Is The Internet Secure?

Comments Off on Is The Internet Secure?

Hacker blogger Quinn Norton is getting a lot of coverage with her blog claiming that the Internet is broken. She argues that every computer and every piece of software we use is vulnerable to hackers because of terrible security flaws. Norton blames these flaws on the fact that developers who face immense pressure to ship software quickly.

Norton says that those bugs may have been there for years unnoticed, leaving systems susceptible to attacks. One of her hacker mates accidentally took control of more than 50,000 computers in four hours after finding a security vulnerability. Another one of her colleagues accidentally shut down a factory for a day after sending a “malformed ping.”

She said that the NSA wasn’t, and isn’t, the great predator of the internet, it’s just the biggest scavenger around. It isn’t doing so well because they are all powerful math wizards of doom. The other problem is software is too complicated and the emphasis placed on security too light.

“The number of people whose job it is to make software secure can practically fit in a large bar, and I’ve watched them drink. It’s not comforting. It isn’t a matter of if you get owned, only a matter of when,” Norton said.

Comments Off on McAffee See Sure In Spam

The first three months of 2013 have seen a surge in spam volume, as well as a growing number of samples of the Koobface social networking worm and master boot record (MBR) infecting malware, according to antivirus vendor McAfee.

After remaining relatively stable throughout 2012, spam levels rose during the first quarter of 2013, reaching the highest volume seen in the past two years, McAfee said in a report released Monday.

The amount of spam originating from some countries rose dramatically, McAfee said. Spam from Belarus increased by 540% while spam originating in Kazakhstan grew 150%.

Cutwail, also known as Pushdo, was the most prevalent spam-sending botnet during the first quarter, McAfee said.

The increased Pushdo activity has recently been observed by other security companies as well. Last month, researchers from security firm Damballa found a new variant of the Pushdo malware that’s more resilient to coordinated takedown efforts.

On the malware front, McAfee has also seen a surge in the number of Koobface samples, which reached previously unseen levels during the first quarter of 2013. First discovered in 2008, Koobface is a worm that spreads via social networking sites, especially through Facebook, by hijacking user accounts.

The number of malware samples designed to infect a computer’s master boot record (MBR) also reached a record high during the first three months of 2013, after increasing during the last quarter of 2012 as well, McAfee said.

The MBR is a special section on a hard disk drive that contains information about its partitions and is used during the system startup operation. “Compromising the MBR offers an attacker a wide variety of control, persistence, and deep penetration,” the McAfee researchers said in the report.

The MBR attacks seen during the first quarter involved malware like StealthMBR, also known as Mebroot; Tidserv, also known as Alureon, TDSS and TDL; Cidox and Shamoon, they said.

Bonets Attack U.S. Banks

Comments Off on Bonets Attack U.S. Banks

Evidence collected from a website that was recently used to flood U.S. banks with junk traffic suggests that the responsible parties behind the ongoing DDoS attack campaign against U.S. financial institutions — thought by some to be the work of Iran — are using botnets for hire.

The compromised website contained a PHP-based backdoor script that was regularly instructed to send numerous HTTP and UDP (User Datagram Protocol) requests to the websites of several U.S. banks, including PNC Bank, HSBC and Fifth Third Bank, Ronen Atias, a security analyst at Web security services provider Incapsula, said Tuesday in a blog post.

Atias described the compromised site as a “small and seemingly harmless general interest UK website” that recently signed up for Incapsula’s services.

An analysis of the site and the server logs revealed that attackers were instructing the rogue script to send junk traffic to U.S. banking sites for limited periods of time varying between seven minutes and one hour. The commands were being renewed as soon as the banking sites showed signs of recovery, Atias said.

During breaks from attacking financial websites the backdoor script was being instructed to attack unrelated commercial and e-commerce sites. “This all led us to believe that we were monitoring the activities of a Botnet for hire,” Atias said.

“The use of a Web Site as a Botnet zombie for hire did not surprise us,” the security analyst wrote. “After all, this is just a part of a growing trend we’re seeing in our DDoS prevention work.”

Does 4G Pose A Security Threat?

Comments Off on Does 4G Pose A Security Threat?

Could 4G Networks give way for more high-risk mobile security implications; Symantec is warning of such a wave of threats.

“We could see a move to the sort of threats that we already see on the wireless and fixed connected network,” John said. “Malware that you usually have on fixed networks, like botnets.

“There aren’t many botnets on mobile devices because the bandwidth’s not there to support it, once you go on to 4G [hackers] could start infecting systems.”

To ensure that enterprises avoid these these security threats, John advised that businesses need to be on their toes more than ever, look closely at everything that’s coming into the network, and not trust anything.

“Companies need to make sure that where traditionally it’s been a firewall with a perimeter with everything in a timeline environment,” John said. “What they need to look at is ‘what are my employees doing’, ‘what information is being shared’ and ‘how do we ensure our information is being protected no matter where it may be’, whether its mobile device, across networks or sitting in a cloud service.”

“This is a change we are going through, but 4G is going to push the need for that change even more so,” she added.

According to John, 4G will also be detrimental to businesses in the way it will add a greater burden for them to ensure that cloud services and mobility – what she calls “two of the biggest security challenges for enterprises and their employees” – are up to scratch.

1 In 5 U.S. PCs Have No Antivirus Protection

Comments Off on 1 In 5 U.S. PCs Have No Antivirus Protection

Nearly a fifth of Windows PCs in the U.S. lack any active security protection, an antivirus vendor stated on Wednesday, citing numbers from a year-long project.

“The scale of this is unprecedented,” argued Gary Davis, the director of global consumer product marketing for McAfee, talking about the scope of his company’s sampling of PC security.

McAfee took measurements from scans of more than 280 million PCs over the last 12 months, and found that 19.3% of all U.S. Windows computers browsed the Web sans security software. Owners of those systems downloaded and used McAfee’s free Security Scan Plus, a tool that checks for antivirus programs and enabled firewalls.

Globally, the average rate was 17%, putting the U.S. in the top 5 most-unprotected countries of the 24 represented in the scans.

Of the unprotected PCs in the U.S., 63% had no security software at all, while the remaining 37% had an AV program that was no longer active. The latter were likely trial versions of commercial antivirus software that had expired.

Antivirus trials are a fact of life in the Windows world. Most new machines come with security software that runs for a limited time. Some new Dell PCs, for example, come with a 30-day trial of McAfee’s Security Center program.

Comments Off on Microsoft Seizes Botnet Servers

Microsoft Corp scored a win in efforts to fight online banking fraud, saying it had seized several servers used to steal login names and passwords, disrupting some of the world’s most sophisticated cybercrime rings.

The software giant said on Monday that its cybercrime investigation group also took legal and technical actions to fight notorious criminals who infect computers with a prevalent malicious software known as Zeus.

By recruiting computers into networks called botnets, Zeus logs the online activity of infected machines, providing criminals with credentials to access financial accounts.

“We’ve disrupted a critical source of money-making for digital fraudsters and cyber thieves, while gaining important information to help identify those responsible and better protect victims,” said Richard Boscovich, senior attorney for the Microsoft Digital Crimes Unit, which handled the investigation in collaboration with the financial industry.

Microsoft’s Digital Crimes Unit is worldwide team of investigators, lawyers, analysts and other specialists who fight cybercrime. A year ago they helped U.S. authorities take down a botnet known as Rustock that had been one of the biggest producers of spam e-mail. Some security experts estimated that in its heyday Rustock was responsible for half the spam in junk email bins.

AES Encryption Cracked

Comments Off on AES Encryption Cracked

CRYPTOGRAPHY RESEARCHERS have identified a weakness in the Advanced Encryption Standard (AES) security algorithm that can crack secret keys faster than before.

The crack is the work of a trio of researchers at universities and Microsoft, and involved a lot of cryptanalysis – which is somewhat reassuring – and still does not present much of a real security threat.

Andrey Bogdanov, from K.U.Leuven (Katholieke Universiteit Leuven), Dmitry Khovratovich, who is full time at Microsoft Research, and Christian Rechberger at ENS Paris were the researchers.

Although there have been other attacks on the key based AES security system none have really come close, according to the researchers. But this new attack does and can be used against all versions of AES.

This is not to say that anyone is in immediate danger and, according to Bogdanov, although it is four times easier to carry out it is still something of an involved procedure.

Recovering a key is no five minute job and despite being four times easier than other methods the number of steps required to crack AES-128 is an 8 followed by 37 zeroes.

“To put this into perspective: on a trillion machines, that each could test a billion keys per second, it would take more than two billion years to recover an AES-128 key,” the Leuven University researcher added. “Because of these huge complexities, the attack has no practical implications on the security of user data.” Andrey Bogdanov told The INQUIRER that a “practical” AES crack is still far off but added that the work uncovered more about the standard than was known before.

“Indeed, we are even not close to a practical break of AES at the moment. However, our results do shed some light into the internal structure of AES and indicate where some limits of the AES design are,” he said.

He added that the advance is still significant, and is a notable progression over other work in the area.

“The result is the first theoretical break of the Advanced Encryption Standard – the de facto worldwide encryption standard,” he explained. “Cryptologists have been working hard on this challenge but with only limited progress so far: 7 out of 10 for AES-128 as well as 8 out of 12 for AES-192 and 8 out of 14 rounds for AES-256 were previously attacked. So our attack is the first result on the full AES algorithm.”

VoIP Ideal Platform For Controlling Botnets

Comments Off on VoIP Ideal Platform For Controlling Botnets

Botnets and their masters can communicate with one other by calling into the same VoIP conference call and exchanging data using touch tones, researchers demonstrated at Defcon.

This gives the botmasters — whose top goals include remaining anonymous — the ability to issue orders from random payphones and disposable cellular phones, say researchers Itzik Kotler and Iftach Ian Amit of security and risk-assessment firm Security Art.

Using phones and the public phone networks eliminates one of the prime tools bot fighters have: taking down the domains of botnets’ command and control servers, the researchers say. If the botmaster isn’t using a command and control server, it can’t be taken down.

In fact, the botmaster can communicate with the zombie machines that make up the botnet without using the Internet at all if the zombies are within a corporate network. So even if a victim company’s VoIP network is segregated from the data network, there is still a connection to the outside world.

In addition to its stealth, the VoIP tactic employs technology that readily pierces corporate firewalls and uses only traffic that is difficult for data loss prevention software to peer into. The traffic is streamed audio, so data loss prevention scanners can’t recognize patterns of data they are supposed to filter, the researchers say.

The downsides of VoIP as a command channel are that it severely limits the number of zombie machines that can be contacted at once, and the rate at which stolen data can be sent out of a corporate network is limited by the phone system. But Kotler and Amit say the connections are plenty big to send commands in.

During their demo at the conference, the pair had an Asterisk open source IP PBX stand in as the corporate PBX. A virtual machine representing a zombie computer on a corporate network called via TCP/IP through the PBX and into a corporate conference call. A BlackBerry, representing the botmaster dialed in over the public phone network to the same conference call.
