Even as technology makes our lives easier, it does not come without its own set of vulnerabilities. Some of these loopholes have the potential to throw most robust systems out of gear. In the year so far, we witnessed the spread of the severe malware called WannaCry, which affected many devices across 150 countries with the number mounting in lakhs in India alone. Even before the impact of WannaCry could be measured to its fullest, a new malware called Judy was discovered stemming from the Google Play Store. While security researchers are still scaling the impact of the new malware, the history of technology is stained with numerous such attacks which went to the extent of threatening national security. Here s a look at the five worst malware attacks ever.
The WannaCry ransomware managed to affect over 200,000 systems across 150 countries. WannaCry ransomware would take control of one s system and the attackers demanded ransom of $300 and $600 in Bitcoin for their encrypted files. India was one of the victim countries and even emerged as one of the top countries to be affected, according to a report by eScan. The report has also shared statistics about which states were hit the most and also which internet networks were impacted.
Of late, if you have received text messages from your friends which direct you to visit WhatsApp's website, remember not to fall for it. The link could potentially harm your device as it has been identified as an adware circulating across the internet. The web link spread in the message takes you to ' .com' instead of the official WhatsApp web portal.
This is that time when all the Man vs Machine conspiracy theories begin to feel legitimate. Over the weekend, the world was hit by a massive cyber attack, which is believed to be the most dangerous ever. This ransomware program, called WannaCry or WannaCrypt or WannaCryptor, spread taking advantage of a vulnerability in Windows XP that Microsoft released a security patch for in March. But computers and networks that didn t update their systems remained at risk.
The world has been hit by, what s being called one of the worst cyber attacks in the history. Up till now, the global cyber-attack has affected more than 200,000 victims in 150 countries, which also includes India. Called WannaCry or WannaCrypt, the ransomware program is spread by taking advantage of a Windows vulnerability that Microsoft released a security patch for in March. But computers and networks that didn t update their systems remained at risk. Russia and Britain were among the worst-hit countries by the attack. The program takes control over a user s system and brings up a message telling users they can recover their files only if they send $300, or in some cases $600 in bitcoins to a specific address.
Very recently, a 22-year-old came in as a blessing in disguise when he accidentally put a halt to a vast number of attacks by the devastating WannaCry ransomware by buying a domain name hidden in the program for about 8.29 (Rs 700 approximately). WannaCry ransomware essentially locks a user out of their computer and demands a ransom paid in BitCoin to return control. The young analyst, whose identity is still concealed, tweets by the name of MalwareTech on Twitter, and works for a security firm called Kryptos Logic. He admitted that he had not realized that buying the domain name would have this fortunate effect.
A ransomware named WCry or WannaCrypt currently has the world on their toes after it managed to infect 75,000 systems in 100 countries. The worm used a tool developed by the National Security Agency that was leaked and demanded $300 in Bitcoin to unlock encrypted files. The ransom demand would double after three days, following which all the encrypted files would be deleted if the users do not pay. In the wake of this massive attack, Microsoft has started issuing security patches to its older operating systems, Windows XP, Windows 8 and Windows Server 2003.
The WannaCrypt ransomware has managed to cause over 75,000 attacks in 100 countries with major alerts being issued everywhere. The ransomware, also known as WannaCry demands $300 in Bitcoin to unlock encrypted files and threatens users to permanently delete them for failure of payments. This malware can infect systems running on the same network and can also come through malicious attachments sent through emails. The Indian Computer Emergency Response Team (CERT-In), through a webcast has addressed all the issues of the WannaCry ransomware, from how it affects a user and organization and its safety measures.
IT security firm Sophos on Thursday announced that its next-generation anti-ransomware CryptoGuard technology is now available with its Sophos Server Protection products. With this optimization, Sophos Server Protection now has signature-less detection capabilities to combat ransomware and can stop the spontaneous encryption of data by ransomware within seconds of detection. Servers are a frequently attacked asset and yet, many are not being protected nor are businesses creating essential back-up incase their data is compromised, Sunil Sharma, Vice President-Sales, India and SAARC at Sophos, said in a statement.
India ranks ninth globally, after countries like the US, Japan, Canada, and Russia, in terms of ransomware attacks, security software firm Symantec on Friday said.
An Android ransomware called Simplocker has been creating havoc in Ukraine, according to security experts ESET. This malware essentially encrypts all the data on an Android device and then demands you to pay ransom to unlock your device.
