Beware the skeletons in your reformatted hard drive
Passport details, credit card information and even nude pictures were found by the programme Trash Trail on second-hand hard drives sold at Sim Lim Square.
By Desmond Ng Posted 19 Feb 2017 16:53 Updated 19 Feb 2017 17:34
Compromising photos were among the data recovered from reformatted hard drives sold at tech stores.
SINGAPORE: Delete all personal information on computer - check. Reformat hard drive - check. Send hard drive to IT shop to clean it again - check.
After all those preventive steps, you would think that all your personal data including private pictures, bank and credit cards details would be wiped and safe from prying eyes.
Well, think again.
Channel NewsAsia documentary The Trash Trail investigated and discovered nude pictures, passport details and even blueprints from a marine engineering company on hard drives that had been reformatted and declared ‘clean’, before being re-sold to consumers.
The documentary also surveyed 1,000 Singaporeans to find out what they did to their electronic devices such as computers and tablets before discarding them - and surprisingly, about 24 per cent of them did nothing, while 37 per cent only reformatted it once.
The episode airs on Monday, Feb 20, at 8pm (SG/HK).
To find out if one’s information is truly deleted from used hard drives, Trash Trail producers bought nine used hard drives from different shops at Sim Lim Square. All the shops said the hard drives had been reformatted, with all information erased.
WATCH: The investigation (2:41)
One salesman said: “(Sometimes) the users’ computer is not able to start up, so they cannot clean it up. When we purchase it, we will use our software to clean it up, to make sure it’s empty before we sell it second-hand.”
The nine hard drives were handed over to Associate Professor Biplab Sikdar from the department of Electrical and Computer Engineering at the National University of Singapore to evaluate. He specialises in how data can be safely transferred, stored and accessed.
The results were shocking. Dr Sikdar found personal information on five of the hard drives, and three had compromising personal photos on them.
They included nude pictures of someone who had presumably gone for plastic surgery. “Personally, I was very shocked to find these kind of … embarrassing and compromising pictures,” he said. “If it went to the wrong person, they might easily blackmail you.”
He also found the passport details of a person with his date of birth, medical records and another person’s bank details - all of which could be used to steal someone’s identity.
And he retrieved sensitive corporate materials from two hard-drives which once belonged to a big offshore marine engineering firm.
“They make ships. And what surprised me was that I found blueprints for the ships here.
“I would have thought that an industry, when they’re disposing of their older laptops, they would be more careful in cleaning up their stuff,” he said, adding that the information could potentially be used for fraud or corporate espionage.
While Dr Sikdar verified that all the nine hard drives had been reformatted, he was able to use software that is easily found online to extract the information.
“Think of your disk like a library… When you delete or format your disk, what happens is that the catalogue is gone. But the books are still there,” he said.
There are several ways to completely destroy your data on a hard drive, he said.
This includes degaussing the hard drive with a powerful magnet at a computer centre to wipe them clean, using software to overwrite all the info, or smashing the hard drive to bits.
CAN'T DELETE PERSONAL DATA ON E-COMMERCE SITES
But there is personal data floating around online that is even trickier or impossible to get rid of - particularly on e-commerce websites.
Many consumers typically provide their personal details such as phone numbers, credit card details and addresses when signing up at such websites. But deleting their accounts is not so simple.
Singapore online shopping site Ezbuy’s co-founder Wendy Liu said that it is not possible for consumers to completely delete their account. Deleting the app on one’s mobile device only gets rid of the app and some temporary data stored.
“But when you install it again, everything from your payment to your order history will still be there.
We have to make sure (these) are kept in our database safely for five years. It is a legal requirement,” she said.
Ms Liu assured Trash Trail that all the data is safeguarded in a database server which has limited access and is equipped with firewalls and encryption. Credit card information is usually stored with a third party.
With more organisations collecting personal data, the Personal Data Protection Act (PDPA) was enacted in Singapore in 2012 which regulates how one’s personal data can be collected, used, disclosed and maintained by organisations.
Christopher Chan, head of legal and government affairs at online grocer RedMart, said that under the PDPA, companies are allowed to keep their data on a consumer for legal purposes or account purposes for a certain number of years.
This is so that if there’s an investigation against the company or customers, or of financial fraud, they need to keep that information accessible so that they can report to the authorities.
He said: “So it doesn’t actually get deleted, but it gets held back with restricted access to it.
“It’s almost impossible to delete all your information online. There’s always going to be some remnant or trace of it.”
Watch more on The Trash Trail on Monday, Feb 20, 8pm (SG/HK).

Alibaba Group plans to invest in Singapore data centre
Alibaba Group plans to invest in Singapore data centre
The deal is part of its US$1 billion investment to drive the growth of Aliyun, its cloud computing arm.
SINGAPORE: Chinese Web giant Alibaba Group on Thursday (Jul 30) announced it will set up data centres in Singapore, as well as Japan, Europe and the Middle East, as part of its US$1 billion investment to drive the growth of its cloud computing arm Aliyun.
In a press release, Alibaba Group CEO Daniel Zhang said Aliyun will serve as an "essential engine" for the company in the new economy which sees the physical and digital arenas becoming increasingly integrated.
"This additional US$1 billion investment is just the beginning. Our hope is for Aliyun to continually empower customers and partners with new capabilities, and help companies upgrade their basic infrastructure," Mr Zhang said. "We want to enable businesses to connect directly with consumers and drive productivity using data."
To do so, it plans to expand its data centre footprint from the five in China and Hong Kong, as well as one in the Silicon Valley in the US.
When asked, Alibaba spokesperson Beckie Wang said in an email that there are no further details on the Singapore data centre currently, such as whether it would be building one from scratch or leasing space from data centre operators here.
Besides data centres, Alibaba Group also has its international Marketplace Alliance Program, a channel programme that offers Aliyun cloud computing services via partners such as Singapore's Singtel.

Dirty Data or "Dirty" Data?
Dirty Data or "Dirty" Data?
Someone told me a lame joke some days ago... Someone told me his eyes were swollen due to dirty / "dirty" data.
Well, this word dirty or "dirty" have different meanings. I have properly use "" to highlight the differences.
"Dirty" can be related to sexual related content.
In database, dirty data is basically inaccurate, incomplete or simply erroneous data. This could be ported in wrongly or entered / keyed in wrongly.

1-Net launches new centre to meet growing data needs
1-Net launches new centre to meet growing data needs
The new data centre, located at Marsiling, will be Singapore’s first Tier III data centre.
SINGAPORE: 1-Net Singapore is launching a new centre to meet growing demand for data hosting and other data-management services, to be ready by the last quarter of 2015.
The new data centre, 1-Net North, will be Singapore’s first Tier III data centre certified by the Uptime Institute, a research organisation and consultancy focused on improving data-centre performance and efficiency.
A Tier III data centre allows for any planned maintenance activity to take place without disrupting operations of hardware located in the centre.
“We’ve seen a shift in the way consumers consume their information over the last few years, and businesses have also responded by changing the way they engage customers. With the opening of this new 1-Net Data Centre, 1-Net aims to become Asia’s data centre of choice,” said Mr Wong Ka Vin, Managing Director of 1-Net.
The company noted that in South-east Asia alone, the online video audience grew about 8 per cent in the past year. South-east Asia also ranks higher than the global average when it comes to consumption of music, movies and entertainment.
1-Net is a MediaCorp enterprise. It currently manages telco-class carrier-neutral Internet data centres, and provides domestic and international connectivity among other services.
The new centre will be more than 200,000 sq ft and will be located at Marsiling. The total investment in the project is expected to be about S$130 million.
1-Net will also be investing an additional S$70 million to fit out the data centre with the technology required to attain the Tier III certification.
To receive this certification, the entire data centre is required to undergo significant testing for uninterrupted operation during maintenance activities.

'Let's try and not have a human do it': How one Facebook techie can run 20,000 servers
'Let's try and not have a human do it': How one Facebook techie can run 20,000 servers
Summary: Facebook on how it has managed to ease the pain of running one of the world's largest fleet of servers.
By Nick Heath | November 25, 2013 -- 12:43 GMT (20:43 SGT)
How many people does it take to run 20,000 servers? In the case of Facebook just the one.
Facebook's low overhead is born of necessity. When you run a computing infrastructure supporting the Likes of more than one billion users worldwide – the less human input needed to keep it ticking over, the better.
The philosophy of the social media giant is if a job doesn't need to be carried out by a person, "let's try and not have a human do it", said Tom Furlong, Facebook's director of site operations.
Facebook cuts manual maintenance of its IT infrastructure wherever possible. Servers and drives can be replaced without tools thanks to their Open Compute Project (OCP) designs, a system called Cyborg fixes tracts of misbehaving servers automatically and tools like Chef help manage thousands of servers at a time.
One of the latest of these manual labour-saving tools is Cluster Planner. Facebook regularly deploys servers in their thousands to meet the constantly changing demands of its business. Cluster Planner helps the company find the best home for these clusters within its global datacentre estate.
"Cluster Planner helps us calculate where we're going to put machines, so we can best utilise the infrastructure that we have," said Furlong.
"It basically replaces an incredibly manual process," he said, adding it had reduced cluster deployment time from days to hours.
Cluster Planner takes a snapshot of what sits where in Facebook's estate. It aggregates data about Facebook's computer systems – such as server components, average CPU utilisation and number of IOPs – and details about the datacentres, including electrical capacity and available floor space.
"It's normally a very cumbersome process for engineers to do the math calculations. With Cluster Planner you can do that very quickly, so what took us days before now takes us hours."
A core challenge for Facebook when cataloguing infrastructure spread across its global datacentres is ensuring consistency in how the data is collected and labelled, so Facebook can properly aggregate data. For example ensuring that data derived from generators at its datacentre in Prineville, Oregon is labelled in the same way as that collected from generators at its Forest City installation, more than 2,500 miles away.
Cluster Planner is in beta, its tools are being worked on and Facebook is in the process of hooking it into all of its datacentres.
Keeping track of Swiss cheese clusters
The make-up of Facebook's datacentres is moulded by the ebb and flow of business demands, with its computing estate changing shape to support alterations to systems and the roll out of new software. Furlong believes Facebook's IT operations could become more efficient by using systems like Cluster Planner to capture information about the composition of server clusters as they change during their lifetime.
"You don't put a server in production and then have [it handling] exactly the same workload during its three year lifespan. It's a moving landscape," said Furlong.
"Over the lifespan of the cluster you start to see things disappearing from it. You get people saying 'Oh there are underutilised resources in that cluster, let's put them in that new cluster that we're bringing up'.
"After a while there's like this 'Swiss cheese' [cluster], which I know by looking at it doesn't have enough machines in it to be used efficiently.
"If we had something that allowed us to better calculate what that 'Swiss cheese' is, we could go back to capacity planning and say 'Hey send us some more stuff' or 'How about we compact this and use some free rows for other things'. Those are the types of things I want us to be able to do over the lifetime of the equipment, so we don't have this static view of the world."
Automating away the pain
Maintaining one of the world's largest fleet of servers could be a massive hassle.
Facebook eases that pain in several ways, such as by using OCP-designed servers, storage and datacentre equipments that have been stripped down to the core components needed to carry out specific computing workloads, an approach that the OCP refers to as 'vanity-free design'.
These designs not only remove unnecessary screws from servers and drives so they can be installed without tools, but also reduce the number of components that can go wrong. The company estimates that using OCP hardware has cut the time its staff spend on maintenance jobs by more than 50 percent.
Also cutting the number of manual repairs are automated software tools like the aforementioned Cyborg, which monitor Facebook's infrastructure and try to correct problems without manual intervention.
"We've said that one datacentre technician can basically handle about 20,000 machines," Furlong said.
"One of the reasons why we can operate as efficiently as we do in terms of server repairs is we have huge numbers of automated systems that collect and analyse data.
"Cyborg goes out and tries to do its own server repairs, like a soft reboot or something that is an easy way to fix a system that's hung up. Cyborg keeps literally thousands of potential tickets from ever hitting a human hand.
"The more stuff we can have a system do, the better. I don't want to employ armies of people to do the things I can automate out. I want the people who are there to do high value work, the more complex repairs, the installs and de-installs, and all the kind of things that you need people to do."
Furlong is also examining ways to cut the manual work needed to add new hardware to Facebook's inventory system, and is considering automated alternatives to its current system of adding items by manually scanning barcodes.
"Say we have a setup where you just snap the new thing in and the system recognises it then updates all of your inventory systems," he said.
While the scale of Facebook's IT operations can be difficult to manage, its size can be an asset when it comes to weeding out problems in the infrastructure. Furlong recalls the company spotting a recurring fault with a small number of motherboards in its OCP servers when they were installed in its Prineville datacentre.
"What we realised was we actually had the same failures in all of our legacy equipment, we just couldn't see it before because the sample sizes were small," he said.
"That's the beauty of having a large sample size to look at, you can knock things out that keep you from having to do a whole bunch of work [in the future]."
If Facebook is to continue to grow its 1.1 billion-strong user base it will need to continue work at sweating its datacentres, but Furlong believes there are plenty more efficiencies to wring out.
"To me that is the Holy Grail of this, to look at that server to datacentre ratio and be able to say 'I can get more servers into my datacentre'," he said.
"I think we do a good job of that today but I absolutely believe there is room for improvement."

Singapore explores metrics guidelines for data centers
Singapore explores metrics guidelines for data centers
HP commissioned to carry out study looking at data center efficiency
Published 23rd March, 2011 by Penny Jones
HP is studying Singapore’s enterprise data centers to create energy efficiency benchmarks that can be used by Singapore’s government to set guidelines and even possibly regulation in future.
Figures on energy consumption and the performance of more than 20 companies with enterprise-sized data center operations will be recorded to devise the baseline, used to asses current and future builds.
Director of HP Critical Facilities Services Ed Ansett, who is based in Singapore, said legal requirements are the first aim of the Singapore Green Data Center Standard project but eventually the research could be used for regulating the data center industry.
“The NEA (National Environment Agency) will probably come out with some guidelines using the information but they mostly want to understand the status of data centers in Singapore, to benchmark a large number of these and then make some recommendations on improving energy efficiency,” Ansett said
At the moment there is no legal requirement for energy efficiency in Singapore but Ansett said a lot of large data center operators do measure power usage effectiveness (PUE).
Data center operators in Singapore have to be conscious of efficiency if they want to overcome high costs associated with power and cooling, according to Ansett.
“In tropical climates like Singapore cooling bills are disproportionately high when compared to commercial buildings in more temperate climates such as Australia,” Ansett said.
“Temperature and humidity is relatively constant and high all year round.”
The Infocomm Development Authority of Singapore is supporting the initiative and will use the data gathered to identify areas for standardization and highlight data center issues, HP said.
The study will highlight mechanical, electrical and operational issues in the data centers studied.

At the moment there is no legal requirement for energy efficiency in Singapore but Ansett said a lot of large data center operators do measure power usage effectiveness (PUE).
Data center operators in Singapore have to be conscious of efficiency if they want to overcome high costs associated with power and cooling, according to Ansett.
“In tropical climates like Singapore cooling bills are disproportionately high when compared to commercial buildings in more temperate climates such as Australia,” Ansett said.
“Temperature and humidity is relatively constant and high all year round.”
The Infocomm Development Authority of Singapore is supporting the initiative and will use the data gathered to identify areas for standardization and highlight data center issues, HP said.
The study will highlight mechanical, electrical and operational issues in the data centers studied.

Data growth remains IT's biggest challenge, Gartner says
Data growth remains IT's biggest challenge, Gartner says
Admins plan to expand data center capacity by the end of '11

Computerworld -
Data growth is the biggest data center hardware infrastructure challenge
for large enterprises, according to a new survey by research firm
Gartner Inc.
"As the global economy begins to revive in 2010 and organizations start to shift focus to a return to growth, IT organizations will be challenged to support the various growth initiatives," said Naveen Mishra, principal research analyst at Gartner.
Last year, Mishra said, many data center managers were forced to defer infrastructure upgrades and extend technology refresh cycles. As a result, those same managers are now hampered with an aging infrastructure or, in some cases, product obsolescence.
"Vendors wishing to tap into this reopening market should propose infrastructure solutions that are high in efficiency and offer scalability as the demand grows, thus helping the companies to prepare for a return to growth," he said.
The survey took place between June and August and involved IT staffers from 1,004 large enterprises in eight countries. The data from it is available online.
In addition to concerns about data growth, 37% of those surveyed named system performance and scalability as the second biggest challenge for them in the coming year, with 36% citing network congestion and connectivity issues.
"While all the top data center hardware infrastructure challenges impact cost to some degree, data growth is particularly associated with increased costs relative to hardware, software, associated maintenance, administration and services," April Adams, research director at Gartner, said in a statement.
In an e-mail response to Computerworld Adams said data capacity on average in enterprises is growing at 40% to 60% year over year due to a number of factors, including an explosion in unstructured data, such as e-mail and documents that have to be stored due to "regulatory requirements that continue to evolve and change."
Survey respondents chose archiving and data "retirement projects" as their most popular approach to dealing with their data explosion. Sixty-two percent indicated they will invest in data retirement efforts or continue to push ongoing efforts through the end of 2011.
Adams said that while survey respondents pointed to data growth as their top challenge, they did not blame a lack of data center capacity as driving their strategic plans. Instead, they indicated business continuity and data availability as their chief reasons.
The second and third most commonly mentioned drivers for strategic change were data containment initiatives, named by 37% of respondents, and maintaining or improving user service levels and satisfaction, which was named by 36% of those surveyed.
Other projects at the top of IT staffers' lists for 2011 include: data security from internal or external hackers; storage consolidation; storage management tools rollouts; and data reduction techniques.
When it comes to technology investments, server virtualization topped the list with 67% of respondents saying they plan to spend money on that in 2011. About 56% of respondents said they also plan to invest in application consolidation. And 51% plan to spend money on blade servers.
Respondents were split when it came to IT budgets, with 44% indicating it would increase over the next year, 40% saying it would stay the same and 14% indicating it would decrease. Two-percent said they didn't know what would happen to their budgets, Adams said.

Nearly half IT shops central to corporate sustainability strategy
Nearly half IT shops central to corporate sustainability strategy |
| As more stakeholders within a company become interested in building a sustainable enterprise, eyes turn to the IT organization and, according to Forrester, rightfully so |

Christopher Mines, senior VP and research director at Forrester, delivers a keynote at the Silicon Valley Leadership Group's Data Center Efficiency Summit 2010 in San Jose IT is becoming central to the way companies tackle corporate sustainability. According to a recent Forrester survey of IT leaders on the subject, 44 percent replied that IT was key in both planning and executing corporate sustainability strategy, said Christopher Mines, senior VP and research director at Forrester. “It organizations are perfectly positioned to be the exemplar … but also the enabler for the rest of the company to improve the sustainability of operations,” Mines said during a keynote address at the Silicon Valley Leadership Group’s Data Center Efficiency Summit in San Jose, California, Thursday. “It has everything to do with IT. IT can be a catalyst (and) a leader across the entire organization.” Ed Kettler, green IT strategist at HP, said in an interview that the observation made perfect sense, since CIO’s have a more comprehensive visibility into companies’ operations than most other executives. “The CIO’s have the collective knowledge of the company,” he said. As companies realize the centrality of IT to operations, members of IT staff are also increasingly starting to spread out across the rest of the organization, Mines said. “IT is becoming the training ground for business-process leaders who move across the company. We see it over and over again at our client companies.” Mines outlined three basic steps in an IT organization’s path to taking the driver’s seat in corporate sustainability. The first is to get IT’s own house in order; the second is to partner with other business-process leaders; and the third is to take the leadership position. A key component in getting IT’s house in order is increasing data center energy efficiency. Organizations approach this differently, but the most popular way is virtualization and consolidation. According to Mines, 68 percent of respondents to the Forrester survey had active virtualization and consolidation programs. Improving energy efficiency of IT is not always a bottom-up process however, with 36 percent of respondents saying they were working on eliminating redundant applications. “If we can reduce the number of applications that our data center is supporting we can reduce the hardware footprint” and the underlying power and cooling infrastructure that supports it, Mines said. Such a decision usually comes from management levels above the data center, however. Kettler said companies that grow through acquisitions – such as HP – are naturally prone to having redundant applications that are being supported by redundant infrastructure. Eliminating such redundancies requires a wider push from the top. “It requires more business change to accomplish,” he said. - wong chee tat :) |

Submarine cable operator Pacnet to build 13 data centers across Asia
Submarine cable operator Pacnet to build 13 data centers across Asia
In run-up to expected IPO, network provider plans to convert landing stations to data centers (2/23/2010)
In run-up to expected IPO, network provider plans to convert landing stations to data centers (2/23/2010)
Network operator Pacnet announced on Tuesday an ambitious plan,
whereby the company will step into the data center provider market,
converting the landing facilities of its submarine cable network in Asia
into data centers.
Pacnet CEO
Bill Barney told Reuters that the company would invest about
$300 million over the next three years, building 10 smaller data centers
and three large ones throughout Asia. According to the news service,
the move is part of the company’s diversification process as it prepares
for an IPO.
“Over the
past few years, we have seen exponential growth in the demand for data
center hosting services and customized applications,” Barney said in a
prepared statement. “Pacnet's cable landing facilities across
Asia are
equipped with massive power, space and capacity, therefore, it is a
natural step for us to move forward in building DLS (data landing
station) facilities to support immediate demands in the marketplace.”
In the
project’s initial phase, Pacnet is planning to launch three data centers
by the end of 2010, with additional sites coming online in 2011.
Locations and details for phase one were not disclosed on Tuesday.
Pacnet
currently operates landing facilities for its submarine fiber lines in Hong Kong, China, Singapore,
Japan, Korea, Taiwan and the
Philippines.
While
building the smaller facilities by itself, Pacnet is planning to partner
with other, at this point unnamed companies on the three larger core
data centers, each expected to cost $250 million or more.
Barney told Dow Jones Newswires that Pacnet was aiming to
raise $500 million through its IPO.

Change to core router by data center provider brings WordPress down
Change to core router by data center provider brings WordPress down
| More than 10 million blogs affected |
| (2/18/2010) |
Popular
blogging platform WordPress
was down for almost two hours on Thursday, following a networking issue
at one of the data centers that host its servers.
The outage,
depriving about 10.2 million blogs of about 5.5 million page views, was
the company’s worst in four years, WordPress founder Matt Mullenweg
wrote in a blog post.
Mullenweg was the founding developer of software that runs much of WordPress “We are still gathering details, but it appears an unscheduled change to a core router by one of our data center providers messed up our network in a way we haven’t experienced before, and broke the site,” he explained. “It also broke all the mechanisms for failover between our locations in San Antonio and Chicago.”
Mullenweg
reassured blog owners that all their data was secure during the
110-minute outage and that WordPress would look for ways to “recover
more gracefully next time and isolate problems like this so they don’t
affect our other locations.”

Asia Pacific data center market growth rate to surpass 16 percent in 2011
| Asia Pacific data center market growth rate to surpass 16 percent in 2011 | ||||||||||||
| With Japan at the forefront, Frost and Sullivan says demand in the region outpaces supply | ||||||||||||
| (2/12/2010) | ||||||||||||
Echoing the words of analysts in the US about the American data
center market, a research firm Frost and Sullivan analyst says that demand for data
center space in Asia-Pacific significantly outpaces supply in the
region and expects growth in the provider market to continue at high
rates.
“Data centre hosting services are a huge, growing business - one that has remained largely insulated from the recession,” Frost and Sullivan’s Chengyu Wu said in a statement, highlighting her new study of the region. “As much as two-fifths of a company's total energy consumption is spent on powering data centres, making the cost of maintaining captive data centers highly prohibitive. “Real estate, of course, is the other significant cost. In fact, over 80 percent of the major data centres in Asia-Pacific are running at close to 90 percent capacity and space is at a premium.” The report cover 14 countries in Asia-Pacific, including Japan. In 2009, the data center services market’s size in the region was about $8 billion, growing at a rate of about 12.8 percent year-over-year. Wu expects the market to grow by 14.7 percent in 2010 and by 16.4 percent in 2011, by which point its size will reach $10.68 million. Japan accounted for the largest portion of the region’s total market revenues in 2009, generating $5.7 billion. Other major Asia-Pacific data center “hubs” are Australia, Singapore, Hong Kong and, to a lesser degree, China, India and Malaysia. Across the region, most demand is driven by “government initiatives towards e-governance and e-readiness.” Remaining 45 percent of the market is driven by Internet media, telecommunications and IT companies, whose sectors continue growing at high rates. |
