Welcome to “Refog” corporate blog.

We are developing programs to monitor user activity of home (Personal Monitor) and office (Employee Monitor) computers, as well as to control usage of your children’s computer (Time Sheriff).

Update to version 7.2.0.1443

13 February 2012

In this program update there are not that many innovations, but it’s worth writing about it as well. It is made almost completely on the basis of joint work by programmers, the technical support department, and actual users of our programs.

In all the programs, we added the feature of capturing user’s messages in the VKontakte (vk.com) social network. Many users have asked me for this for a long time now.

The Ukrainian language was added to the programs’ interface. The translation was done by one of our users, so thank you very much to him.

The Ukrainian language

We are continuing to work on improving the encrypting system for logs in Employee Monitor and Terminal Monitor. In extremely rare cases, it works incorrectly and greatly slows down the work of the program.

Thanks to reports like this from our users, we were able to solve the problem. In the next versions of the programs, we will be able to get rid of it completely.

Updates and improvements, version 6.4.3.1164

13 February 2012

We did not announce any changes we made in our programs for a long time while we were releasing new versions. Therefore, today we decided to hold a slight review and recall everything.

One of the most important updates was the development of a module for protecting financial information. This is a special script that automatically searches for lines in the program’s logs that are similar to credit card numbers, and deletes them from the monitoring journal. Screenshots made at that moment are also deleted.

These protective mechanisms work only in cases when this is possible and do not guarantee protection in absolutely all cases. The script is gradually being improved to minimize false alarms and errors. It cannot be turned off since its very existence carries out legislative norms.

For the programs Employee Monitor and Terminal Monitor, due to many requests from the users, a feature was added of configuring log storage in a local or network folder specified by the user.

configuring log storage

A lot of work was done to improve the support of the latest versions of internet browsers (Opera, Firefox).

There was an improvement to message monitoring in Facebook, the social network.

The Turkish and Polish languages were added to the program interface.

France was secretly intercepting the British government correspondence

28 November 2011

France was secretly intercepting the British government correspondenceDuring his speech at the McAfee Focus Event in London, David Blunkett, the former British Minister of Internal Affairs, provided some details about the 2000 negotiations with Nicolas Sarcozy (the French Minister of the Interior at that time), where the latter admitted that France had been intercepting electronic correspondence of the British embassy.

The future president of France thereby confirmed the fact of active hi-tech espionage on the state level. These days, virtually all government agencies use strong data encryption for all correspondence, especially for messages sent abroad.

During his address, Blunkett also raised the topic of “advanced persistent threats (APT’s), which usually target the IT systems of public organizations and government agencies.

One of the characteristics of APT’s is that hackers disguise their activities using the tools already present in the system being attacked, exploit commonly used ports, mask their activities as actions performed by standard applications or even hide their control communications in HTML comments, which allows them to capture highly-confidential and secret information for prolonged periods of time.

User monitoring: Facebook’s new patent

28 November 2011

facebookSome time ago, Facebook got involved in a new scandal. The hype was based around the fact that HTTP cookies saved by Facebook on users’ computers remained there even after they logged out of the social network, thus casting a shadow of suspicion on it developers and created an impression that they could be monitoring users’ activities on other sites.

On September 25, Facebook officials sent a statement to major mass media assuring the public that they were not monitoring users’ activities on other websites.

However, on September 22, the US Patent and Trademarks Office received a patent application for a technology that made it possible to track user’s actions outside a social network.

It’s clear that “to patent” does not equal “to use”, but hardly anybody can guarantee that the social network will not get such functionality in the future.

Spying scandal in Germany

10 November 2011

Chaos Computer Club (CCC), a Germany-based hacker group, published a proof of the use of spyware by the government, which resulted in a serious scandal on the highest level.

The spyware mentioned in the publication was found on a laptop that belonged to a person who was suspected of illegal export of pharmaceuticals. The program was allegedly installed during a customs inspection at an airport.

This program captures the URL’s of visited websites and email communications and then sends the collected data to a remote server, presumably outside the country. Besides, it allows the operator to upload and launch any applications on a remote computer.

Joachim Hermann, the Minister of Interior of Bavaria, confirmed that state authorities in this land had been using spyware since 2009, but refused to provide specific examples. In his opinion, this practice in not in breach of any laws, although this issue is subject to further discussion. Authorities from three other lands (Baden-Württemberg, Brandenburg and Niedersachsen) also confirmed that they had been using similar software.

In response to the furious public reaction, some high-profile authorities were forced to provide comments on the situation.

Germany’s Minister of Justice, Sabine Leutheusser-Schnarrenberger, and Chancellor Angela Merkel demanded that a thorough investigation of the incident be conducted. The result of this investigation should be a mechanism aimed at protecting the citizens’ rights to privacy.

Therefore, Germany’s laws related to the use of spyware may change considerably in the nearest future.

ZoneDefense: advanced mobile protection

10 November 2011

ZoneDefenseAirPatrol has presented a new wireless security technology called ZoneDefense. This system uses a new unique approach to the prevention of corporate data leaks.

This a narrowly focused technology that prevents data leaks through mobile devices and applications. ZoneDefense integrates into the structure of a protected building (with its elements being placed in every room) and detects the location of any mobile device with 6-7 foot accuracy.

However, this is not all the system is capable of.

Not only does it allow to find devices within a protected building, but can also make them work according to system-wide rules. Depending on the rules, ZoneDefense can either allow or block the work of both devices and specific mobile applications using a number of parameters: device ownership by a specific employee, type of application, movement direction and even proximity of other devices.

This system can also set off an alarm notifying the security service about a possible data leak or detection of a suspicious device in an unauthorized area.

Google: online safety guide for children

10 November 2011

family safetyAccording to a research conducted by the Internet Development Fund, children in Europe and the NIS states usually know more about the Internet than their parents do.

From the one hand, this is a positive and logical thing. From the other hand – we don’t really know how children understand the basics of online security. Regular incidents involving Internet fraud and harassment prove that the problem is very real and the level of online threat awareness among teenagers is very low.

You can try to shield your kids from such threats in many ways, but you must be ready to face the fact that an Internet-savvy teenager won’t have any problems finding a workaround. And that is why you, as a parent, will have to explain the basics of online security to them.

Google has published a guide for parents and teachers that explains how online dangers can be avoided and how the rules of online conduct can be efficiently communicated to minors. All of these materials have been published as “Family Safety Center”.

The guide contains articles written by Google and other companies working on the problems of online security for children.

However, we should not forget than no technology, even the most advanced one, will ever be able to replace parental control and proper upbringing.

GPRS: channel hacked

10 November 2011

gprsKarsten Nohl, a German network security and cryptography expert, announced the discovery of a relatively simple technique of intercepting and decrypting data transmitted over the GPRS protocol.
His team also discovered that many mobile carriers use a low-security variant of GPRS, while some of them disable GPRS traffic encryption altogether.
There can be two reasons behind such ignorant attitude of mobile carriers to the security of their clients’ data:

  • An attempt to save on equipment required for proper data protection.
  • Deliberate disablement of data encryption for retaining access to clients’ data.

Karsten Nohl claims that his discovery is far from being theoretical: his team was able to capture and decrypt data in T-Mobile, O2 Germany, Vodafone and E-Plus networks. What made matters worse was that they did not have to use cumbersome equipment (they used a reflashed Motorola C-123 phone) or expensive software (they only used publicly available freeware). Even in this case, they managed to capture data in the radius of 5 km.
The details of this technique have not been published yet to avoid damage to the clients of cell phone companies. The research group believes that it’s high time that mobile operators did their homework and configured their GPRS gateways and checked all cryptographic systems, as the methodology they followed will be made public shortly.
However, Russian operators were quick to react: according to “The Big Three” (Beeline, Megafon, MTS), they don’t see how this could jeopardize their clients’ security and suggest using better-protected technologies, such as 3G.

Data Mining: From the General to the Specific

31 August 2011

data miningData mining (deep data analysis) — a collective term used for a set of methods for detecting previously unknown, unusual, interpretable and practically useful knowledge in arrays of data that can be used for making decisions in various fields of human activities.

It’s common knowledge that complete privacy in today’s world is a utopian concept: our names appear in different kinds of lists and reports on a daily basis. We pay for goods and services with credit cards, use mobile phones, buy tickets… And when it comes to the Internet, we leave a colossal number of tracks: from the addresses of visited pages to search engine queries – everything can be intercepted, logged and stored in a single database.

The primary purpose of data mining lies in the analysis of huge amounts of data in such databases (involving special analytical patterns).

For instance, there is nothing suspicious about money being transferred from one account to another. Or about somebody buying a plane ticket to a large city. Or buying a large shipment of fertilizers. Or, let’s say, buying a kitchen timer or several cheap mobile phones from an online store. However, if all of these purchases were made by a single person, the local anti-terror force should definitely take a closer look.

It would seem that combining so many heterogeneous pieces of information is an immensely complex task. However, such a system is absolutely possible and may have been in operation for some time now.

The Total Information Awareness program was developed by the Pentagon from 2002 through 2003 and was aimed at detecting suspicious behavioral patterns. Following a number of public protests, it was renamed to Terrorism Information Awareness (TIA) and became nearly completely confidential. The report of the Department of Homeland Security mentions three active programs of this type. Similar solutions are being developed by other countries as well: China, the United Kingdom, Israel and Germany.

The legitimacy of such analysis is a matter of harsh public debate and none of the parties has been able to decide whether security is more important than privacy (or vice versa). And while the debate is in full swing, data collection and analysis are booming on the Internet – the Law hasn’t fully set foot on this land yet.

Software helped get back a stolen notebook

28 June 2011

Software helped get back a stolen notebookNot long ago, an Apple notebook owner (Josh Kaufman) had an unfortunate experience. His MacBook was stolen and the police were not interested in investigating. Usually, that would be the end of the story, but in this case something else happened.

Shortly before the robbery, the owner installed a program on his MacBook which secretly tracked the user. It took screen shots, photos from the inbuilt camera and even identified the probable location of the device by using the Wi-Fi network. The software regularly sent all this data to the owner’s email.

The owner of the stolen computer wrote a blog called “This Guy Has My MacBook” and began to publish the screenshots and photographs in the hope of identifying the thief or of getting the police more interested. Fortunately, the thief didn’t wipe the disk or sell the laptop, but kept and used it himself. As a result Kaufman quickly collected a lot of photographs of the thief sleeping, sitting at the computer, driving his car, etc.

A few days later the police arrested the criminal and returned the stolen property to its owner. According to the police, they were able to make the arrest thanks to the photographs provided by Kaufman.

This story has caused a lot of discussion among MacBook owners. Many of them have asked Apple to add an app similar to the already existing services Find My iPhone and Find My iPad for iOS to the next MacOS version.
