What is Ransomware?
Ransomware is a type of malware used for data kidnapping. It takes your data hostage by encrypting it using supposedly unbreakable encryption algorithms and then demands payment in exchange for the decryption key. It’s called ransomware. That term is the combination of the word ransom and the “ware” in software. True ransomware is an infection in your computer put there by a hacker or online thief. It’s a special form of malware, intended to scare some money out of its victim.
You need to know about ransomware because it is a real threat and it’s not going away soon. But there are also ways to avoid it, and you need to know that as well. Scroll down and read the entire article and find out protect from ransomware?
History of Ransomware Attack
It’s been around since about 2005, but attackers have greatly improved on the scheme with the development of ransom cryptware, which encrypts your files using a private key that only the attacker possesses, instead of simply locking your keyboard or computer.
And these days ransomware doesn’t just affect desktop machines or laptops; it also targets mobile phones. In 2015, ransomware in the wild masqueraded as a porn app. The so-called Porn Droid app targeted Android users and allowed attackers to lock the phone and change its PIN number while demanding a $500 ransom from victims to regain access. Also that year, the FBI issued an alert warning that all types of ransomware are on the rise. Individuals, businesses, government agencies, academic institutions, and even law enforcement agents have all been victims. The malware can infect you via a malicious email or website, or attackers can deliver it straight to your computer if they’ve already infected it with a backdoor through which they can enter. Most recently, a global cyber-attack spread ransomware to countless computers over 150 countries.
In 2012, Symantec gained access to a command-and-control server used by the Crypto Defence malware and got a glimpse of the hackers’ haul based on transactions for two Bitcoin addresses the attackers used to receive ransoms. Out of 5,700 computers infected with the malware in a single day, about three percent of victims appeared to shell out for the ransom. At an average of $200 per victim, Symantec estimated that the attackers hauled in at least $34,000 that day. Extrapolating from this, they would have earned more than $394,000 in a month. And this was based on data from just one command server and two Bitcoin addresses; the attackers were likely using multiple servers and Bitcoin addresses for their operation. Prevent from Ransomware by following the simple steps below.
How Ransomware Works?
Ransomware is malware that locks your keyboard or computer to prevent you from accessing your data until you pay a ransom, usually demanded in Bitcoin. The digital extortion racket is not new.
When a computer is infected, the ransomware typically contacts a central server for the information it needs to activate, and then begins encrypting files on the infected computer with that information. Once all the files are encrypted, it posts a message asking for payment to decrypt the files – and threatens to destroy the information if it doesn’t get paid, often with a timer attached to ramp up the pressure.
Why Ransomware Attack?
It would happen like this: You go on your computer, perhaps open your browser and/or visit a website, and a message pops up saying that if you don’t cough up some money in a day or two, some or all of the files on your computer are going to be deleted…or at least made totally inaccessible to you. Imagine seeing that message one morning…it would be such a shock. And there would be no way to know whether it’s true or not…and because ransomware blackmail does exist, it can feel very scary.
Maybe that’s why so many people—and we’re talking about smart people who aren’t easily duped—would rather pay up than run the risk of losing data on their computer. It might surprise you, but there are actual instances where police departments and city agencies have paid the crooks’ ransom demands rather than run the risk of losing the data that might be in jeopardy. And this may sound odd, but the crooks seem to price their crimes just right, because most of the time the ransom seems to be a reasonable amount, as opposed to outrageous. It might be $50-600, instead of thousands of dollars. By paying up, the victim is ensured that their data wasn’t lost.
Unfortunately, they also helped the online thieves obtain ill-gotten money…and even more incentive to blackmail other innocent victims.
Who are the Ransomware Attackers?
The creators of this piece of ransomware are still unknown, but WannaCry is their second attempt at cyber-extortion. An earlier version, named WeCry, was discovered back in February this year: it asked users for 0.1 bitcoin (currently worth $177, but with a fluctuating value) to unlock files and programs.
Ransomware Recent Attack- 2017 12th May
What is WannaCry?
The malware that has affected Telefónica in Spain and the NHS in Britain is the same software: a piece of ransomware first spotted in the wild by security researchers Malware Hunter Team, at 9.45am on 12 May. Less than four hours later, the ransomware had infected NHS computers, albeit originally only in Lancashire, and spread laterally throughout the NHS’s internal network. It is also being called WanaCrypt0r 2.0, Wanna Decryptor 2.0, WCry 2, WannaCry 2 and Wanna Decryptor 2.
What Happens After Ransomware Attack?
WannaCry malicious software has hit Britain’s National Health Service, some of Spain’s largest companies including Telefonica, as well as computers across Russia, the Ukraine and Taiwan, leading to PCs and data being locked up and held for ransom.
The ransomware uses a vulnerability first revealed to the public as part of a leaked stash of NSA-related documents in order to infect Windows PCs and encrypt their contents, before demanding payments of hundreds of dollars for the key to decrypt files.
The co-ordinated attack had managed to infect large numbers of computers across the health service. Less than six hours after it was first noticed by security researchers. In part due to its ability to spread within networks from PC to PC.
How To Protect From Ransomware Attack?
Users should regularly back up their data and ensure security updates are installed on their computer as soon as they are released. Up-to-date back-ups make it possible to restore files without paying a ransom. Friday’s global cyber-attack exploited vulnerabilities in some versions of Microsoft Windows. Microsoft has released software patches for the security holes, although not everyone has installed those updates.
Users should look for malicious email messages that often masquerade as emails from companies or people they regularly interact with online. It is important to avoid clicking on links or opening attachments in those messages.
1. Back up your files
The greatest damage people suffer from a ransomware attack is the loss of files, including pictures and documents. The best protection against ransomware is to back up all of the information and files on your devices in a completely separate system. A good place to do this is on an external hard drive that isn’t connected to the internet. This means that if you suffer an attack you won’t lose any information to the hackers.
Businesses often save copies of their data to external servers that won’t be affected if their main network is attacked.
2. Be suspicious of emails, websites and apps
For ransomware to work hackers need to download malicious software onto a victim’s computer. This is then used to launch the attack and encrypt files. The most common ways for the software to be installed on a victim’s device is through phishing emails, malicious adverts on websites, and questionable apps and programs.
People should always exercise caution when opening unsolicited emails or visiting websites they are unfamiliar with. Never download an app that hasn’t been verified by an official store, and read reviews before installing programs.
3.Use an antivirus program
An age-old computer security tip, antivirus programs can stop ransomware from being downloaded onto computers and can find it when it is. Most antivirus programs can scan files to see if they might contain ransomware before downloading them. They can block secret installations from malicious adverts when you’re browsing the web, and look for malware that may already be on a computer or device.
4.Always install updates
Companies often release software updates to fix vulnerabilities that can be exploited to install ransomware. It is therefore advisable to always download the newest version of software as soon as it is available.
5. Never pay the ransom
Victims of ransomware attacks are advised to never pay the fee as it encourages attackers and may not result in files being recovered. There are some programs that can help decrypt files. Or, if you have a backup, you can restore your device from that.
6. Be aware of security risks
Follow basic security protocol. Don’t click on questionable links or open suspicious attachments.
7. If hit, act immediately
Some organisations disconnect computers as a precautionary measure. Shutting down a network can prevent the continued encryption — and possible loss — of more files. Hackers will sometimes encourage you to keep your computer on and linked to the network. Don’t. If you face a ransom demand and are locked out of your files, experts discourage paying ransoms because it gives incentives to hackers but doesn’t guarantee all your files will be restored.
Best Way to Avoid Ransomware Attack
Microsoft issued the software that protects against the WannaCry worm on March 14. While WannaCry spreads via a Windows bug, other forms of malicious software can spread through flaws in other software on your computer, such as Adobe Inc.’s Flash and Oracle Corp.’s Java. So the next time you see a prompt for a software update from those programs or others on your system, take the time to install it. It helps.
By now, all of the antivirus vendors have updated their products to detect WannaCry, along with countless other ransomware variants. Antivirus software provides no guarantee that you will avoid the very latest attacks. But it is a sensible step that security experts recommend. The good news that is Kaspersky Antivirus was providing the best features to avoid ransomware attack from attackers.
