Everyone must comply with government requests to disclose information. How far should one go when disclosing such information? This is up to the company. In a recent trend, several big IT companies including Apple, Facebook, Google and Microsoft among others teamed up to propose a change in US legislatures concerning governments spying on its citizens. The reform would make government surveillance “consistent with established global norms of free expression and privacy and with the goals of ensuring that government law enforcement and intelligence efforts are rule-bound, narrowly tailored, transparent, and subject to oversight”.

In light of recent security outbreaks, Apple introduced a number of changes to its security policies. As one of the leading security companies and a major supplier of forensic software for iOS devices, ElcomSoft is being constantly approached by IT security specialists, journalists and forensic experts. The most common question is: how will the new security measures affect iOS forensics? (more…)
Two years ago, ElcomSoft analyzed some 17 password management applications for mobile platforms only to discover that no single app was able to deliver the claimed level of protection. The majority of the apps relied upon proprietary encryption models rather than utilizing iOS exemplary security model. As a result, most applications were either plain insecure or provided insufficient security levels, allowing a competent intruder to break into the encrypted data in a matter of hours, if not minutes. Full report (PDF) is available here.
Today, we need stronger security more than ever. Was the urge for stronger security recognized by software makers, or are they still using the same inefficient techniques? In order to find out, we decided to re-test some of the previously analyzed products. Keeper® Password Manager & Digital Vault will the first subject for dissection.
Back in 2012, we weren’t much impressed by security in any of the apps we analyzed. Two years later, Keeper developers claimed they’ve successfully implemented the suggestions we made during the last analysis. The developers claim to have used 256-bit AES encryption, PBKDF2 key generation, BCrypt, and SHA-1 among other things. Let’s see if these improvements lead to stronger security.
With little news on physical acquisition of the newer iPhones, we made every effort to explore the alternatives. One of the alternatives to physical acquisition is over-the-air acquisition from Apple iCloud, allowing investigators accessing cloud backups stored in the cloud. While this is old news (we learned to download data from iCloud more than two years ago), this time we have something completely different: access to iCloud backups without a password! The latest release of Phone Password Breaker is all about password-free acquisition of iCloud backups. (more…)
Do you think you know everything about creating and using backups of Apple iOS devices? Probably not. Our colleague and friend Vladimir Bezmaly (MVP Consumer security, Microsoft Security Trusted Advisor) shares some thoughts, tips and tricks on iTunes and iCloud backups.
Mobile phones are everywhere. They are getting increasingly more complex and increasingly more powerful, producing, consuming and storing more information than ever. Today’s smart mobile devices are much more than just phones intended to make and receive calls. Let’s take Apple iPhone. The iPhone handles our mail, plans our appointments, connects us to other people via social networks, takes and shares pictures, and serves as a gaming console, eBook reader, barcode scanner, Web browser, flashlight, pedometer and whatnot. As a result, your typical iPhone handles tons of essential information, keeping the data somewhere in the device. But what if something happens to the iPhone? Or what if nothing happens, but you simply want a newer-and-better model? Restoring the data from a backup would be the simplest way of initializing a new device. But wait… what backup?
Users in general are reluctant to make any sort of backup. They could make a backup copy once after reading an article urging them to back up their data… but that would be it. Apple knows its users, and decided to explore the path yet unbeaten, making backups completely automatic and requiring no user intervention. Two options are available: local backups via iTunes and cloud backups via Apple iCloud.
Soon after releasing the updated version of iOS Forensic Toolkit we started receiving questions about the new product. Did we really break iPhone 5? Does it truly work? Are there limitations, and what can you do about them? We decided to assemble all these questions into a small FAQ. If you’d rather read the full, more technical version of this FAQ, visit the following page instead: Elcomsoft iOS Forensic Toolkit FAQ. Those with non-technical background please read along.
Some time ago, I wrote a blog post on hacked Yahoo!, Dropbox and Battle.net accounts, and how this can start a chain reaction. Companies seem to begin recognizing the threat, and are starting to protect their customers with today’s cutting edge security: two-factor authentication.
A word on two-factor authentication. In Europe, banks and financial institutions have been doing this for decades. Clients needed to enter an extra piece of information from a trusted media in addition to their account credentials in order to authorize a transaction such as transferring money out of their account. For many years, bank used printed lists of numbered passcodes serving as Transaction Authentication Numbers (TAN). When attempting to transfer money out of your bank account, you would be asked to enter a passcode number X. If you did not come up with the right code, the transfer would not execute. There are alternatives to printed TAN’s such as single-use passwords sent via a text message to a trusted mobile number or interactive TANs generated with a trusted crypto token or a software app installed onto a trusted phone.
Online services such as Microsoft or Google implement two-factor authentication in a different manner, asking their customers to come up with a second piece of an ID when attempting to access their services from a new device. This is supposed to prevent anyone stealing your login and password information from gaining access to your account from devices other than your own, verified PC, phone or tablet.
The purpose of two-factor authentication is to prevent parties gaining unauthorized access to your account credentials from taking any real advantage. Passwords are way too easy to compromise. Social engineering, keyloggers, trojans, password re-use and other factors contribute to the number of accounts compromised every month. An extra step in the authorization process involving a trusted device makes hackers lives extremely tough.
At this very moment, two-step authentication is being implemented by major online service companies. Facebook, Google and Microsoft already have it. Twitter is ‘rolling out two-factor authentication too.
A recent story about a journalist’s Google, Twitter and Apple accounts compromised and abused seems to have Apple started on pushing its own implementation of two-factor authentication.
Two-Factor Authentication: The Apple Way
Apple’s way of doing things is… different. Let’s look at their implementation of two-factor authentication.
It’s been a while since we released the new version of Elcomsoft Phone Password Breaker that allows downloading backups from iCloud (read the press release). Many customers all over the world are already using this new feature intensively, but we still get many questions about its benefits, examples of cases when it can be used and how to use it properly. We also noticed many ironic comments in different forums (mostly from users without any experience in using iOS devices and so have no idea what iCloud backups actually are, I guess), saying that there is nothing really new or interesting there, because anyone with Apple ID and password can access the data stored in iCloud backup anyway.
Well, it seems some further explanation is needed. If you are already using EPPB (and this feature in particular) you will find some useful tips for future interaction with iCloud, or even if you don’t have an iOS device (you loser! just kidding :)) please go ahead and learn how iCloud can be helpful and dangerous at the same time.

The story about PGP becomes really funny.
Three and a half years ago (in April 2009) our company took part in InfoSecurity Europe in London. I should confess that London is one of my favourite cities; besides, I love events on security — so that I was really enjoying that trip (with my colleagues). But something happened.
