Is Changing Your Password Often A Good Idea?
Comments Off on Is Changing Your Password Often A Good Idea?
Carnegie Mellon University professor Lorrie Cranor, who is the US FTC’s technology guru, has debunked a myth that it is a good idea to change your password often.
Talking to Ars Technica she said that while frequent password changes can lock hackers out they make make security worse.
She told the BSides security conference in Las Vegas that frequent password changes do little to improve security and very possibly make security worse by encouraging the use of passwords that are more susceptible to cracking.
A study published in 2010 by researchers from the University of North Carolina at Chapel Hill more or less confirmed her views. The researchers obtained the cryptographic hashes to 10,000 expired accounts that once belonged to university employees, faculty, or students who had been required to change their passcodes every three months. Researchers received data not only for the last password used but also for passwords that had been changed over time.
By studying the data, the researchers identified common techniques account holders used when they were required to change passwords. A password like “tarheels#1″, for instance (excluding the quotation marks) frequently became “tArheels#1″ after the first change, “taRheels#1″ on the second change and so on. Or it might be changed to “tarheels#11″ on the first change and “tarheels#111″ on the second. Another common technique was to substitute a digit to make it “tarheels#2″, “tarheels#3″, and so on.
“The UNC researchers said if people have to change their passwords every 90 days, they tend to use a pattern and they do what we call a transformation. They take their old passwords, they change it in some small way, and they come up with a new password.”
The researchers used the transformations they uncovered to develop algorithms that could predict changes with great accuracy.
A separate study from researchers at Carleton University showed that frequent password changes hamper attackers only minimally and probably not enough to offset the inconvenience to end users.

Spotify Says ‘No’ To Sales Rumor

Comments Off on Spotify Says ‘No’ To Sales Rumor
Daniel Ek, co-founder of Swedish music streaming service Spotify which boasts the largest paid subscriber base in the world, said on Thursday he had no intention of selling the company.
While investors believe privately owned Spotify is probably heading for a public listing, some industry analysts see the loss-making company as a takeover target for a larger tech giant with deeper pockets.
“My selfish ambition with Spotify is just trying to show … that we can create one of those super companies here in Europe,” he told journalists at the symposium Brilliant Minds, which aims to bring artists and musicians together with the tech community.
Asked if that meant he was not up for selling the firm, Ek said: “I’m not going to sell, no.”
Spotify, founded in 2006, pays more than 80 percent of its revenue to record labels and artists and has not yet shown a profit as it spends to grow internationally. It competes in a business crowded with formidable rivals such as Apple Music, Google Music and YouTube.
Many other European tech start-ups have been swallowed up by bigger Silicon Valley competitors.
Ek said Silicon Valley got an earlier start in building up its tech giants but that Europe finally has the right conditions to support its own entrepreneurs.
“For the first time now there’s an ecosystem around it with capital and experience that can actually help guide entrepreneurs,” he said.
“The number one advice I tell everyone is ‘don’t sell’, because that’s the biggest problem we have. All these things could grow gigantic if you just kept the course and kept doing what you’re doing,” he added.
Last year Spotify made an operating loss of 184.5 million euros ($205 million), widening from 165.1 million in 2014.
Spotify, whose investors include Northzone, DST Global and Accel, does not disclose details about its ownership but the co-founders no longer own a majority, having sold off stakes.

IBM Acquires EZSource
The digital transformation revolution is already in full swing, but for companies with legacy mainframe applications, it’s not always clear how to get in the game. IBM announced an acquisition that could help.
The company will acquire Israel-based EZSource, it said, in the hopes of helping developers “quickly and easily understand and change mainframe code.”
EZSource offers a visual dashboard that’s designed to ease the process of modernizing applications. Essentially, it exposes application programming interfaces (APIs) so that developers can focus their efforts accordingly.
Developers must often manually check thousands or millions of lines of code, but EZSource’s software instead alerts them to the number of sections of code that access a particular entity, such as a database table, so they can check them to see if updates are needed.
IBM’s purchase is expected to close in the second quarter of 2016. Terms of the deal were not disclosed.
Sixty-eight percent of the world’s production IT workloads run on mainframes, IBM said, amounting to roughly 30 billion business transactions processed each day.
“The mainframe is the backbone of today’s businesses,” said Ross Mauri, general manager for IBM z Systems. “As clients drive their digital transformation, they are seeking the innovation and business value from new applications while leveraging their existing assets and processes.”
EZSource will bring an important capability to the IBM ecosystem, said Patrick Moorhead, president and principal analyst with Moor Insights & Strategy.
“While IBM takes advantage of a legacy architecture with z Systems, it’s important that the software modernizes, and that’s exactly what EZSource does,” Moorhead said.
Large organizations still run a lot of mainframe systems, particularly within the financial-services sector, noted analyst Frank Scavo, president of Computer Economics.
“As these organizations roll out new mobile, social and other digital business experiences, they have no choice but to expose these mainframe systems via APIs,” Scavo said.
But in many large organizations, skilled mainframe developers are in short supply — especially those who really understand these legacy systems, he added.
“Anything to increase the productivity of these developers will go a long way to ensuring the success of their digital business initiatives,” Scavo said. “Automation tools to discover, expose and analyze the inner workings of these legacy apps are really needed.”
It’s a smart move for IBM, he added.
