Cyberattack's impact could worsen in 'second wave' of ransomware; Jakarta hospital hit

NY [U.S.], May 14 (ANI): The World's biggest cyber attack which has hit 200,000 victims in at least 150 countries threatens to create more havoc on Monday when people return to work.

Ransomware attacks are some of the most immediately damaging forms of cyber-attacks that affect home users, enterprises and governments equally.

NHS England said that, as of 3pm on Monday, two hospitals remained on divert following the attack, down from seven on Sunday.

The ransomware is called "Wannacry" and locks up your computer and forces you to pay the hackers to get all your stuff back - probably making you want to cry in the process.

Riverbank IT Management managing director Malcolm Newdick said: "Last week's ransomware attack was the most risky malware attack we have seen".

The NHS says it employs more than 1.5 million people, making it one of the world's biggest employers along with the U.S. Department of Defense, Walmart and the Chinese army.

The virus, which took control of users' files and demanded payment to allow access, forced many Britain hospitals to cancel treatments, appointments, and even compel emergency rooms to turn people away.

"While the spread of the Ransomware appears to have temporarily slowed, it is still critical that businesses and individuals patch the operating systems on their computers", a statement from the Australian Cyber Security Centre (ACSC) said.

Cyber security experts have said the majority of the attacks targeted Russia, Ukraine and Taiwan.

Proofpoint and a British cybersecurity researcher teamed up on Friday to derail the attack that was said to strike at least 100,000 organisations in 150 countries.

In a statement following the second meeting of Holyrood's resilence committee after the largest-ever global cyber attack last Friday, it was confirmed there had been no spike in hacking incidents after organisations returned to work yesterday. It essentially relies on victims clicking on or downloading the attachment, which causes the program to run and infect your computer with ransomware.

Other Windows systems had also been affected and just 4.7% of NHS systems were still running XP, he said. The organization that oversees United Kingdom hospital cybersecurity said that last month it alerted the trusts about the Windows vulnerabilities and sent a patch to fix it.
