What is Ransomware?
Ransomware is a malicious attack that locks computers to deprive of accessing data until the victim pays the ransom, usually demanded in Bitcoin.
The racket of digital extortion had begun in 2005, and with the time, attackers have gone a step ahead on the scheme with the birth of ransom cryptware that encrypts data with a private key, instead of simply sealing your computer. Its example of ruining businesses comes from a recent global cyber attack on many computers over 150 countries.
From desktop machines and laptops now it has entered to mobile phones. In 2015, ransomer tricked mobile users by masquerading as a porn app. The self-styled Porn Droid app attacked Android users and changed the PIN number while demanding a $500 ransom from to retrieve data.
The FBI issued an alert in the same year to caution about the rise of ransomware. Individuals, businesses, academic institutions, government agencies and even law enforcement agents have all faced the cyber disaster. The malware can enter in your computer through a malicious email or website, or attackers can straightway deliver if they have already infected it by entering through a backdoor.
Types of Ransomware
Ransomware has been looming around in many forms for the past two decades, but it made the first appearance in 2013 with CryptoLocker. The original CryptoLocker botnet was eliminated from existence in May 2014, but with an extortion of nearly $3 million globally.Hackers have developed the new versions by copying CryptoLocker approach, although the variants are different their ways of attacks.
The objection to CryptoWall raised just after the downfall of the CryptoLocker. It came into existence in 2014, and its variants have appeared with the names, including Crypto Bit, CryptoWall 3.0. Like CryptoLocker, CryptoDefense, and CryptoWall 2.0.
Cloud--A panacea to Ransomware
The best way to battle against ransomware is to outplay hackers and barring not to enter systems by any method. The strategy starts with the daily backup along with the robust disaster recovery plan in place so that even if your IT systems become the victim, you won’t need to pay the ransom.
Though backups do work but not every time especially when the opponent is notoriously powerful. If attacked by ransomware, customers can retrieve data from an old unaffected machine version controlled by cloud service provider before the attack. With data availability, it is not sure that business can work with the same flow until production systems get cleared of ransomware effects.
Cloud-based disaster recovery is the solution to tackle it. Users can failover production to a cloud service provider in the event of the attack and restore data within seconds.
