iPhone, Mac owners: How to stymie hackers extorting Apple, threatening to wipe devices

Hackers claiming to have hundreds of millions of iCloud credentials have threatened to wipe date from iPhones, iPads and Macs if Apple does not fork over $150,000 within two weeks."This group is known for getting accounts and credentials, they have gotten credentials in the past," said Lamar Bailey, director of security research and development at Tripwire, of the purported hackers. "But whether they have that many ... who knows?"There's another reason for not panicking, Bailey said: People can quickly make their accounts more secure, assuming the criminals have only collected, not actually compromised the iCloud accounts by changing millions of passwords.To read this article in full or to leave a comment, please click here

Worth Reading: Just Press Reboot

After you pass security at Schiphol, Amsterdam’s international airport, go past the Christian Dior boutique and leave the Pretentious and Overpriced Mediocre Chocolate Shop (maybe not the exact name) on your left. On the wall you will see a big red button labeled “Reboot Schiphol.” Just press it in case your flight is delayed. Not really, but that is what Reuters seems to believe. —ACM

Google cites progress in Android security, but patching issues linger

The chances of you encountering malware on your Android phone is incredibly small, according to Google.By the end of last year, less than 0.71 percent of Android devices had installed a "potentially harmful application," such as spyware, a Trojan, or other malicious software.That figure was even lower, at 0.05 percent, for Android phones that downloaded apps exclusively from the Google Play store.The internet giant revealed the figures in a new report detailing its efforts to making the Android OS secure. Thanks to better app review systems, the company is detecting and cracking down on more malware.To read this article in full or to leave a comment, please click here

New opportunities for augmented reality

Augmented reality, virtual reality and mixed reality are three realities that exist on the reality-virtuality continuum—and they are probably the three terms you have heard again and again.  However, there is a fourth reality you probably haven’t heard of—diminished reality.Diminished reality can be thought of as the opposite of augmented reality. Augmented reality (AR) enhances our reality by overlaying digital elements like 3D models on the physical world.  Contrary to that, diminished reality (DR) diminishes parts of the physical world. It removes unwanted objects in our view.To read this article in full or to leave a comment, please click here

Know your encryption workarounds: a paper

As The 21st Century Encryption Wars continue with no end in sight, security experts Bruce Schneier and Orin Kerr have collaborated on a paper that seeks to establish a common understanding of one aspect of the clash: encryption workarounds.  The authors consciously avoid policy recommendations, but rather hope to better the understanding of those who will do so in our political and law enforcement arenas.From the paper’s abstract: The widespread use of encryption has triggered a new step in many criminal investigations: the encryption workaround. We define an encryption workaround as any lawful government effort to reveal an unencrypted version of a target's data that has been concealed by encryption. This essay provides an overview of encryption workarounds. It begins with a taxonomy of the different ways investigators might try to bypass encryption schemes. We classify six kinds of workarounds: find the key, guess the key, compel the key, exploit a flaw in the encryption software, access plaintext while the device is in use, and locate another plaintext copy. For each approach, we consider the practical, technological, and legal hurdles raised by its use.To read this article in full or to leave a comment, please click here

Hackers threaten to wipe millions of Apple devices, demand ransom

A group of hackers is threatening to wipe data from millions of Apple devices in two weeks if the company doesn’t pay them US$150,000. The group, which calls itself Turkish Crime Family, claims to have login credentials for more than 627 million icloud.com, me.com and mac.com email addresses. These are email domains that Apple has allowed for users creating iCloud accounts over the years. Even though the Turkish Crime Family hasn't been in the media spotlight before, its members claim that they've been involved in selling stolen online databases in private circles for the past few years. The group said via email that it has had a database of about 519 million iCloud credentials for some time, but did not attempt to sell it until now. The interest for such accounts on the black market has been low due to security measures Apple has put in place in recent years, it said.To read this article in full or to leave a comment, please click here
