Cyber chaos may grow at start of workweek

RBI has asked banks to follow the instructions of government organisation CERT-In to prevent the attack by ransomware, "WannaCry", which has impacted various IT networks in over 150 countries.Indian Computer Emergency Response Team (CERT-In) has come out with list of dos and don'ts and webcast on how to protect networks from the global ransomware attack. A group known as Shadow Brokers released Eternal Blue along with a collection of hacking tools from the spy agency last month. Those include a known and highly unsafe security hole in Microsoft Windows, tardy users who didn't apply Microsoft's March software fix, and malware created to spread quickly once inside university, business and government networks.

Soon after the theft, Microsoft released a patch that fixed the vulnerability.

That means an out-of-date, unsupported operating system is more popular than any version of Windows 8, any version of Mac OS X, and Linux.

Consumers are also at risk.

Straight out of an episode of Mr. Robot, WannaCry (Wcry, WannaCrypt, WanaCrypt0r 2.0, or Wanna Decryptor) is a malicious software package that infects computers running Microsoft Windows.

In Britain, where the virus first raised global alarm when it caused hospitals to divert ambulances on Friday, it gained traction as a political issue just weeks before a general election.

Britain's National Health Service said about a fifth of NHS trusts - the regional bodies that run hospitals and clinics - were hit by the attack on Friday, leading to thousands of canceled appointments and operations. Russian Federation is believed to have been badly hit, with various entities such as banks, ministries, public institutions such as railways and phone operators being attacked.

Ian Brady's ashes 'not to be scattered at Saddleworth Moor'
A spokesman for the Mersey Care NHS Foundation Trust did not confirm that Brady died, but said he had no oxygen for a while. He and girlfriend Myra Hindley buried their victims' bodies on Saddleworth Moor, near Manchester in northwestern England.

But what do you do if the ransomware arrives on your computer? The advice is to update Windows to ensure you are protected.

However, not all Windows users out there updated their systems, especially organizations who rely on older systems. But critics argue that this "stockpiling" of vulnerabilities makes ordinary people less safe, as they can leak and fall into the wrong hands.

Microsoft says, 'We also know that some of our customers are running versions of Windows that no longer receive mainstream support. After that, we have to click on accept Windows software updates. Back up your data on an offline hard drive. 4. "Attackers update their software. other attackers will learn from the method and will carry out attacks". The attack is unique, according to Europol, because it combines ransomware with a worm function, meaning once one machine is infected, the entire internal network is scanned and other vulnerable machines are infected. This helps limit the spread of ransomware if hackers do get into your system.

British media were hailing as a hero a 22-year-old computer security whiz who appeared to have helped stop the attack from spreading by discovering a "kill switch" - an internet address which halted the virus when activated.

"The numbers are still going up", Wainwright said.

A local hospital said one of its computers was found early on Sunday to have been attacked by the WannaCry ransomware virus, one day after the government reported there had been no incidents of ransomware infection involving government agencies and hospitals in Taiwan. Cyber security expert Brian Krebs wrote: "I find it depressing to think of the massive financial damage likely wrought by this ransom campaign in exchange for such a comparatively small reward". The tech giant urged governments to use and store their cyber warfare tools responsibly.
