Another ransomware is loose on the streets now; it is known as CryptoWall – nastier and more dangerous than its predecessor CryptoLocker. Let’s read about this and other important IT security news and updates.
After CryptoLocker, CrytoWall is Spreading the Scare on the Internet
The infamous CryptoLocker ransomware was triumphantly taken down in late May, thanks to law enforcement aided by security organizations. But, it seems like another nastier ransomware called CryptoWall has put security companies back to work. By using tactics such as spam emails, drive-by-downloads and other malware programs, CryptoWall has taken the Internet by storm. Some arecalling it as the most destructive ransomware threat till date. It functions exactly like what CryptoLocker used to do – infects the victim’s computer, encrypts files, and demands ransom to release the files. Over 600,000 computers have been taken down by CryptoWall; this includes 22,582 computers in India. Ransom value ranges from $200 – $10,000, payable only via Bitcoin. In the past six months, creators of this ransomware were able to pull in a whopping $1 million through their exploits. Readers are advised to steer clear from software from unverified publishers, and spam/unwanted/unsolicited emails. It is also essential to have your computer secured with a reliable antivirus that offers real-time protection against malicious and infected websites.

Going by this, attackers can launch a man-in-the-middle attack on affected routers and hijack the victim’s Internet traffic, steal information relaying through it including personal and financial data.
