How to protect your PC after a weekend wave of cyber attacks

How to protect your PC after a weekend wave of cyber attacks

A massive cyberattack known as WannaCry wreaked havoc all over the world this past weekend, and although this particular ransomware is already dying out, new ones may be cropping up. These don't prevent a ransomware attack but they will filter out some of the emails that carry ransomware. It wasn't immediately clear to what degree nations across Asia were being affected by the attack Monday.

At the same time, the cyber warheads, including Russian Federation and China, continued to thwart the day.

Cyber security experts are urging those effected to not pay the ransom, stating that those effected might not get their files back even if they do pay the fee. He says Chinese security companies have been offering their help.

"The United States, more than probably any other country, is extremely careful with their processes about how they handle any vulnerabilities that they're aware of", Tom Bossert, the White House homeland security adviser, said at a press briefing on Monday.

Americans should hope their nuclear command-and-control systems are safe, but it is possible that may not matter. Fresh incidents reported from Kerala and Bengal yesterday.

It is a given that governments around the world are busy developing aggressive programs that can be used to incapacitate the computer networks of rivals.

Hackers bait users to click on infected email links, open infected attachments or take advantage of outdated and vulnerable systems. ATMs were run after the security was assured.

For financial transactions, ensure the use of Secure Socket 7.

WannaCrypt ransomeware spreads through the University of Milano-Bicocca. In addition to the version of Wannacry 2.0, two newer versions have also been detected. Bkav's free device will help users to check whether their computer have been affected by Wanna Crypt which is extremely unsafe as it is capable of stealing information and decrypting the entire system that has been infected. The next step is to warn that computer data could be distorted. But catching ransomware attackers is generally much more hard, unless they slip up. The first is that there has been no "second wave" of the ransomware ever since the blogger named MalwareTech accidentally halted the spread of the attack. With this attack, Abrams recommends trying to recover the "shadow volume" copies some versions of Windows have.

Once your files are encrypted, your options are limited. "But at the same time, I also know that if you're someone who's been affected and you've lost all your children's photographs or you've lost all your data or you lost your thesis, sometimes $300 is worth it, you know?"

The encryption is very strong: without the decryption key or a recent uninfected backup, the data is gone forever. "Organisations need to make use of it".

It was unclear Sunday whether Microsoft was delivering the new Windows XP, Windows 8 and Windows Server 2003 patches via the standard Windows Update maintenance service, or if users were required to manually download the appropriate fixes from the Update Catalog.

Lastly there are, of course, the attackers, who kidnapped precious data and demanded ransom be paid.

What the affected are doing with Wannacry?

In addition to Microsoft's Security Bulletin MS17-010 that patched the vulnerability in March, the company also issued a separate patch on Friday for users of older and unsupported operating systems such as Windows XP. In part, that's simply because of the logistical complications involved in paying ransom to unlock thousands of computers within the short time frame demanded by the hackers behind the WannaCry attack. The cyber criminals have demanded a fee of about USA $300 in crypto-currencies like Bitcoin for unlocking the device.
