Tool cracks ransomware

Published

on

Kaspersky Lab has  released a new decryptor for files that have been locked with the latest version of the CryptXXX malware.

After releasing decryption tools for two variants of CryptXXX ransomware in April and May 2016, Kaspersky Lab has  released a new decryptor for files that have been locked with the latest version of the malware. This malicious programme was capable of infecting thousands of PCs around the world since April 2016, and it was impossible to fully decrypt the files affected by it. But not anymore. The free RannohDecryptor tool by Kaspersky Lab can decrypt most files with .crypt, .cryp1 and .crypz extensions.

CryptXXX is one of the most actively distributed and dangerous families of ransomware: for a long time criminals used the Angler and Neutrino exploit kits to infect victims with this malware. These two kits were considered among the most effective in terms of successfully infecting targets.

Since April 2016, Kaspersky Lab products have registered attacks by CryptXXX against at least 80,000 users around the world. More than half of them located in only six countries: the US, Russia, Germany, Japan, India and Canada. But these are only users that were protected by Kaspersky Lab’s detection technologies. Unfortunately the total number of attacked users is much higher. The actual figure is not known, but Kaspersky Lab experts estimate that there may be several hundred thousand infected users.

“Our regular advice to the victims of different ransomware families is the following: even if there is currently no decryption tool available for the version of malware that encrypted your files, please don’t pay the ransom to criminals. Save the corrupt files and be patient – the probability of a decryption tool emerging in the near future is high. We consider the case of CryptXXX v.3 as proof of this advice. Multiple security specialists around the world are continuously working hard to be able to help victims of ransomware. Sooner or later the solution to the vast majority of ransomware will be found,”  said Anton Ivanov, security expert at Kaspersky Lab.

The decryption tool can be downloaded from Kaspersky Lab’s website and from Nomoreransom.org – the website of the not-for-profit initiative launched in 2016  by the National High Tech Crime Unit of the Netherlands’ police, Europol’s European Cybercrime Centre and two cyber security companies, Kaspersky Lab and Intel Security, with the goal of helping victims of ransomware to retrieve their encrypted data without having to pay the criminals. The global fight against ransomware continues to gather pace with more than 30 new partners from both the public and private sector joining the No More Ransom project.

“Our data shows that, over the last year, attacks on businesses increased three-fold, which represents a change from an attack every 2 minutes to one every 40 seconds. For individuals the rate of increase went from every 20 seconds to every 10 seconds. This was matched by a surge in new types of ransomware. Too many people still believed they had no alternative but to pay up, even though many that paid the ransom never got their files back – including one in five businesses. And this project provides an alternative – to unlock your files without paying the ransom,” said Jornt van der Wiel, Security Researcher at the Global Research and Analysis Team at Kaspersky Lab.

When will we stop calling them phones?

If you don’t remember when phones were only used to talk to people, you may wonder why we still use this term for handsets, writes ARTHUR GOLDSTUCK, on the eve of the 10th birthday of the app.

Do you remember when handsets were called phones because, well, we used them to phone people?

It took 120 years from the invention of the telephone to the use of phones to send text.

Between Alexander Graham Bell coining the term “telephone” in 1876 and Finland’s two main mobile operators allowing SMS messages between consumers in 1995, only science fiction writers and movie-makers imagined instant communication evolving much beyond voice. Even when BlackBerry shook the business world with email on a phone at the end of the last century, most consumers were adamant they would stick to voice.

It’s hard to imagine today that the smartphone as we know it has been with us for less than 10 years. Apple introduced the iPhone, the world’s first mass-market touchscreen phone, in June 2007, but it is arguable that it was the advent of the app store in July the following year that changed our relationship with phones forever.

That was the moment when the revolution in our hands truly began, when it became possible for a “phone” to carry any service that had previously existed on the World Wide Web.

Today, most activity carried out by most people on their mobile devices would probably follow the order of social media in first place – Facebook, Twitter, Instagram and LinkedIn all jostling for attention – and  instant messaging in close second, thanks to WhatsApp, Messenger, SnapChat and the like. Phone calls – using voice that is – probably don’t even take third place, but play fourth or fifth fiddle to mapping and navigation, driven by Google Maps and Waze, and transport, thanks to Uber, Taxify, and other support services in South Africa like MyCiti,  Admyt and Kaching.

Despite the high cost of data, free public Wi-Fi is also seeing an explosion in use of streaming video – whether Youtube, Netflix, Showmax, or GETblack – and streaming music, particularly with the arrival of Spotify to compete with Simfy Africa.

Who has time for phone calls?

The changing of the phone guard in South Africa was officially signaled last week with the announcement of Vodacom’s annual results. Voice revenue for the 2018 financial year ending 31 March had fallen by 4.6%, to make up 40.6% of Vodacom’s revenue. Total revenue had grown by 8.1%, which meant voice seriously underperformed the group, and had fallen by 4% as a share of revenue, from 2017’s 44.6%.

The reason? Data had not only outperformed the group, increasing revenue by 12.8%, but it had also risen from 39.7% to 42.8% of group revenue,

This means that data has not only outperformed voice for the first time – as had been predicted by World Wide Worx a year ago – but it has also become Vodacom’s biggest contributor to revenue.

That scenario is being played out across all mobile network operators. In the same way, instant messaging began destroying SMS revenues as far back as five years ago – to the extent that SMS barely gets a mention in annual reports.

Data overtaking voice revenues signals the demise of voice as the main service and key selling point of mobile network operators. It also points to mobile phones – let’s call them handsets – shifting their primary focus. Voice quality will remain important, but now more a subset of audio quality rather than of connectivity. Sound quality will become a major differentiator as these devices become primary platforms for movies and music.

Contact management, privacy and security will become critical features as the handset becomes the storage device for one’s entire personal life.

Integration with accessories like smartwatches and activity monitors, earphones and earbuds, virtual home assistants and virtual car assistants, will become central to the functionality of these devices. Why? Because the handsets will control everything else? Hardly.

More likely, these gadgets will become an extension of who we are, what we do and where we are. As a result, they must be context aware, and also context compatible. This means they must hand over appropriate functions to appropriate devices at the appropriate time. 

I need to communicate only using my earpiece? The handset must make it so. I have to use gesture control, and therefore some kind of sensor placed on my glasses, collar or wrist? The handset must instantly surrender its centrality.

There are numerous other scenarios and technology examples, many out of the pages of science fiction, that point to the changing role of the “phone”. The one thing that’s obvious is that it will be silly to call it a phone for much longer.
