The Hacker News - Cybersecurity News and Analysis: unlock files

If your computer has been infected with PyLocky Ransomware and you are searching for a free ransomware decryption tool to unlock or decrypt your files—your search might end here. Security researcher Mike Bautista at Cisco's Talos cyber intelligence unit have released a free decryption tool that makes it possible for victims infected with the PyLocky ransomware to unlock their encrypted files for free without paying any ransom. The decryption tool works for everyone, but it has a huge limitation—to successfully recover your files, you must have captured the initial network traffic (PCAP file) between the PyLocky ransomware and its command-and-control (C2) server, which generally nobody purposely does. This is because the outbound connection—when the ransomware communicates with its C2 server and submit decryption key related information—contains a string that includes both Initialization Vector (IV) and a password, which the ransomware generates randomly to encrypt the file

Almost three years after the arrest of two young Dutch brothers, who pleaded guilty to their involvement in creating and distributing CoinVault ransomware malware , a district court in Rotterdam today sentenced them to 240 hours of community service. In 2015, the two suspects — Melvin (25-year-old) and Dennis van den B. (21-year-old) — were arrested from Amersfoort on suspicion of involvement in CoinVault ransomware attacks. The duo was arrested by law enforcement with the help of researchers from Kaspersky Labs , who reverse-engineered the malware and found the full name of one of the suspects and their IP address left accidentally on the command and control server. CoinVault ransomware campaign that began in May 2014 was one of the most successful file-encrypting ransomware program of its time that encrypted over 14,000 Windows computers worldwide, primarily the Netherlands, the US, the UK, Germany, and France. Just like other ransomware attacks, the sole intent of CoinVau

If your PC has been infected by WannaCry – the ransomware that wreaked havoc across the world last Friday – you might be lucky to get your locked files back without paying the ransom of $300 to the cyber criminals. Adrien Guinet, a French security researcher from Quarkslab, has discovered a way to retrieve the secret encryption keys used by the WannaCry ransomware for free, which works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008 operating systems. WannaCry Ransomware Decryption Keys The WannaCry's encryption scheme works by generating a pair of keys on the victim's computer that rely on prime numbers, a "public" key and a "private" key for encrypting and decrypting the system's files respectively. To prevent the victim from accessing the private key and decrypting locked files himself, WannaCry erases the key from the system, leaving no choice for the victims to retrieve the decryption key except paying the ransom to
