'WannaCry' ransomware attack: What we know so far

Q: How many people have been affected by the current strain, WannaCry?

The apps, the website, and customer service lines were not affected by the attack, Miller said, noting that it would take a few more days for departure boards to return to normal operation. But that number has nearly certainly risen as people in Asia - who had logged off for the workweek before WannaCry began spreading - have returned to work. Seven of the 47 affected trusts were still having IT problems on Monday.

And that's just a measure of the electronic consequences of WannaCry. In the United Kingdom, where the initial attack threw parts of the health care system into chaos Friday, the government scheduled an emergency meeting Monday afternoon to discuss the attack. "These differ in the way they motivate the user into paying the ransom". In reality, doing that may be more hard than it sounds, either because of corporate cultures that don't prioritize security or because of a lack of funding to upgrade to the latest and greatest.

"This was not a tool developed by the NSA to hold ransom data", homeland security adviser Bossert said at Monday's White House briefing. Reports suggest that over two lakh systems globally could have been infected by the malicious software that blocks access to a system until a sum of money is paid.Earlier in the day, central transmission utility Power Grid said it has put sufficient firewalls to deal with the global cyberattack and consumers need not fear sudden outages. Microsoft has tried to convince companies to stop using SMBv1 for some time, as it has other problems aside from this flaw. He added that the USA government does not recommend paying the ransom and warned that making a payment to the hackers doesn't guarantee that access to computer files will be restored. "They've complacently dismissed warnings which experts, we now understand, have made in recent weeks".

Q: What if I don't have the luxury of fighting the ransomware? Once it's downloaded, the update file will walk you through the install process. But the next best thing you can do is help reduce the odds of being hit next time.

Q: Who's being targeted? The company offered another patch on Friday for older operating systems, including Windows XP. If not, update right away.

"This was general objective malware and not a targeted virus". As Apple has gained more marketshare, its products have become a much bigger target for attackers.

Cybercriminals appear to have used the EternalBlue exploit stolen from the NSA to develop the ransomware, which locks up computers and then moves laterally though networks to infect others. "The biggest issue is the rampant use of pirated Windows software, extensive use of Windows XP, and poor patch maintenance, which will cause havoc for India", the company said.

On Monday, private-sector sleuths found a clue about potentially who's responsible for the WannaCrypt attack.

Microsoft released a patch for this vulnerability in March, but networks that had neglected to upgrade their systems were still vulnerable to attack. But word got out when a hacker group known as the Shadow Brokers dumped a bunch of leaked NSA information onto the Internet in April.

Aside from taking a position on the wider outcome and implication of what will become a notorious cyberattack, Smith also took the time to underline Microsoft's commitment to resolving the situation-beginning with a dedicated force of 3,500 security engineers now working to help customers around the world recover their systems. Most importantly, such a convention would commit governments to turning over software vulnerabilities when they find them - rather than exploiting them to break into enemy computers - so that companies can patch them.

Q: How can I protect myself?

"NCSC and NCA are working with Europol and other global partners to make sure we all collect the right evidence, which we need to do to make sure we have the right material to find out who has done this and we go after them".

The cyber attack affected many NHS facilities that use a 15-year-old operating system for its virtual infrastructure, which likely contributed to its vulnerability.

Back up your computer and store the safety version in the cloud or on a drive that is not connected to your computer. He said infection rates slowed over the weekend.

At work, check with your IT administrator to make sure your organization's devices are protected from WannaCry.

Keep in mind to treat unexpected emails with caution, and read up on phishing - one of the most common types of social engineering attacks used by attackers to compromise machines.

Security firm Digital Shadows said on Sunday that transactions totalling $32,000 had taken place through Bitcoin addresses used by the ransomware.
