India issues do's and don'ts to fight back cyber attack

  • Ransomware cyber-attack a wake-up call Microsoft

That's why it's called ransomware. Experts say this vulnerability has been understood among experts for months, yet too many groups failed to take it seriously.

Theft of the software was reported in April, when it was published by the Shadow Brokers, a group that has been linked to Russian Federation.

Other tools from the presumed NSA toolkit published by the Shadow Brokers have also been repurposed by criminals and are being sold on underground forums, researchers said.

"As cybercriminals become more sophisticated, there is simply no way for customers to protect themselves against threats unless they update their systems", Smith wrote.

To begin with, the worm has been nearly too successful, having hit more than 200,000 victims - many times more than are usually caught out by ransomware aimed at large organisations. Besides installing the updates, Microsoft also advises that the SMBv1 protocol is disabled, as it is an old protocol that has been superseded by newer versions.

The ransomware attack carried out Friday has hit some 200,000 hospitals, companies and government offices in more than 150 countries.

Sixteen National Health Service organizations in the United Kingdom were hit, and some of those hospitals canceled outpatient appointments and told people to avoid emergency departments if possible.

Microsoft said it had taken the "highly unusual step" of releasing a patch for computers running older operating systems including Windows XP, Windows 8 and Windows Server 2003.

It asked users not to open attachments in unsolicited e-mails, even if they come from people in your contact list, and never click on a URL contained in an unsolicited e-mail, even if the link seems benign.

"This attack is a powerful reminder that information technology basics like keeping computers current and patched are a high responsibility for everyone, and it's something every top executive should support", he said.

With much of the world still reeling from the digital breach that prevented people from receiving hospital care, a second wave of what European officials have called "the biggest ransomware attack ever" could be devastating, according to Washington Times.

Install Microsoft's official patch. Back up your data on an offline hard drive. 4.

In 2016, Motherboard reported hospitals across the United Kingdom run old, outdated Windows systems - legacy technology that no longer receives updates.

Organizations are scrambling to apply the latest security patch to their computers to prevent the spread of the attack. Several Chinese government bodies, including police and traffic authorities, reported they had been impacted by the hack, according to posts on official microblogs. A 22-year old security researcher in the United Kingdom discovered a "kill-switch" to initially stop the spread of the attack.

For one thing, the attackers or copycat attackers may have developed new versions of the worm, although a British-based security researcher who thwarted an earlier version of the worm told Reuters most of these reports had been proven false.

Experts say the spread of the virus had been stymied by a security researcher in the U.K. Hackers have issued new versions of the virus that cyber security organizations are actively trying to counter and stamp out.

Dowling notes unplugging an infected computer may not solve the problem with recent ransomware attacks, but isolating the infected computer is important. He warned that more people may be hit by the virus Monday when they return to work and switch on their computers.

"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.
