All evolution comes with challenges and the dark world of cybercrime continues to thrive and is this year's second most reported economic crime. The recent NHS computer hack using Wanna Decryptor ransomware shut down IT systems with 75,000 attacks in 99 countries. The unprecedented ransomware breach froze computers across the health service with hackers threatening to delete files unless a ransom was paid. The passwords were scrambled with the MD5 algorithm, which nowadays is easy to crack. According to Zdnet.com, the unidentified hacker explained his motives for the attack: "I heard the database was getting traded around so I decided to dump it myself – like I always do". He said it was "mainly just for the challenge and training my pentest skills." He exploited a union-based SQL injection vulnerability in the site's software, a flaw he said was "easy to find."
