Spanish Multinational Launches Free Tool to Decrypt Files Affected by VCryptor Ransomware
On June 3, Spain-based telecommunications conglomerate, Telefónica, released a free tool to recover data encrypted by the VCryptor ransomware.
The tool, VCrypt Decryptor, was created as part of an international initiative titled “No More Ransomware”. This alliance was established by McAfee, Europol, Politie, and Kaspersky. It is one of several tools that aim to decrypt almost 134 types of ransomware.
VCrypt’s attack method
According to ElevenPaths, Telefonica’s specialized cybersecurity unit, VCryptor creates a password-protected .zip file in which it stores all encrypted data. It then generates new files with the extension “.vcrypt,” to replace the original files.
The ransomware then launches a message notifying the victim that the attack has been perpetrated. The are instructed to pay the attackers a ransom through cryptocurrencies in order to restore access to the files, with most hacker’s currency of choice being Bitcoin (BTC).
The free tool created by ElevenPaths aims to take advantage of a weak point in VCryptor’s encryption password method.
Telefonica’s cybersecurity division has also been involved in creating free tools to decrypt files affected by PopCorn ransomware.
Cointelegraph reported on an alliance between Interpol and the cybersecurity firm, Kaspersky. Together they launched a campaign called “Anti-Ransomware Day”, set on May 12. The purpose of the day is to raise awareness about the effects of ransom-centric cyberattacks, which continue to affect people and businesses all over the world.

Bitcoin may still be up 135% from March’s lows, but the cryptocurrency’s technical outlook is far from bearish. After peaking at $10,000 multiple times over the past month, showing BTC does not yet have the momentum to clear resistances, the cryptocurrency slid as low as $8,625 on Sunday evening in a move that liquidated approximately $20 million worth of BitMEX longs. There are many analysts saying that this is a precursor to further losses. One trader, for instance, explained that Bitcoin’s weekly chart has just printed a textbook “tweezers top,” marked by two candles with the same-sized body in succession. It’s a sign that is indicative of impending downside. Chart from trader “Chonis” (@BigChonis on Twitter). Adding to this, five out of seven of IntoTheBlock’s foremost market signals — Smart Price, Net Network Growth, In The Money, Bid-Ask Volume Imbalance, and Large Transactions — are currently in a “bearish” zone for Bitcoin.

Bitcoin prices tanked to multi-month lows but is slowly recovering, reeling back after a bear maul. While Bitcoin snaps back, some other details are also emerging. Hash Rate Drops According to discoveries from TokenAnalyst, the number of Bitcoin blocks mined from between Mar 10th and 20th dropped to 16,550 from the expected 19,800 minutes based on an estimation of a 10 minutes block generation time. That means, within that time of price and hash rate slumps, the average generation time rose by 1.9 minutes to 10 minutes. But it gets grimmer for the world’s most valuable coin. The 7-day moving average for the network’s hash rate fell to 94.6 EH/s from 120.6 EH/s.

The decision by Coinbase to launch a price oracle has been lauded by some as an astute, bold, and wise move. Their secure and timestamped BTC/USD and ETH/USD feeds secured by their systems will be freely available and some now interpret this as a direct competition with Chainlink. Rumors now emerge that Chainlink admin at Telegram groups are censoring users for mentioning this Coinbase oracle. Distinctively, Coinbase will, in a way, eliminate the middleman, that is Chainlink, and make available their data to any relayer willing to use this data for smart contracts activation via the Coinbase Pro API. That they also chose Ethereum highlights how the blockchain is a market leader in DeFi and a boost not only for ETH but for DeFi apps that are built on the pioneer smart contracting platform.
