A computer malware that has spread across 150 countries appears to be
slowing down, with few reports of fresh attacks in Asia and Europe on
Monday.
However staff beginning the working week have been told to be careful.
The WannaCry ransomware started taking over users' files on Friday,
demanding $300 (£230) to restore access.
Hundreds of thousands of computers have been affected so far. Computer
giant Microsoft said the attack should serve as a wake-up call.

BBC analysis of three accounts linked to the ransom demands suggests
only about $38,000 (£29,400) had been paid by Monday morning.
However, the ransomware warning said that the cost would double after
three days, so the payments may increase.
It threatens to delete files within seven days if no payment is made.
Among the organisations targeted worldwide have been Germany's rail
network Deutsche Bahn, Spanish telecommunications operator Telefonica,
US logistics giant FedEx and Russia's interior ministry.
How has Monday been so far?
Many firms employed experts over the weekend to try to prevent new
infections.
The picture now appears better in Europe.
Senior spokesman for Europol, Jan Op Gen Oorth, told Agence France-Presse:
"The number of victims appears not to have gone up and so far the
situation seems stable in Europe, which is a success.

"It seems that a lot of internet security guys over the weekend did
their homework and ran the security software updates."
The UK's National Crime Agency tweeted: "We haven't seen a second spike
in WannaCry ransomware attacks, but that doesn't mean there won't be
one."
The badly affected National Health Service said seven out of 47 trusts
that were hit were still facing serious issues.
Carmaker Renault said its plant in the northern town of Douai would not
reopen on Monday as it dealt with the cyber-attack.
In Asia, a significant slowing of the malware was also reported:
Australia: Only three small-to-medium sized businesses reported being
locked out of their systems
South Korea: Only nine ransomware cases. One cinema chain was unable to
display trailers
Indonesia: Records at two hospital blocked
Japan: Both Nissan and Hitachi reported some units had been affected,
but effects small
China: Hundreds of thousands of computers suffered initially, China's
Qihoo tech firm said. Universities, with older systems, particularly
badly hit. Some payment systems and government services affected, but
less than feared
Banking systems across the region were largely unaffected.
Who is behind the attack?
This won't take long. Nobody knows. Europol's Jan Op Gen Oorth said: "A
bit early to say... but we are working on a decrypting tool".
Associated Press quoted Tim Wellsmore, of US security firm FireEye, as
saying: "We expect this is a small operation... They just happened to
hit the mother lode."
Russian President Vladimir Putin said: "Russia has absolutely nothing to
do with it."
Should people pay?
Companies in Asia and Europe have been warning employees to be careful
when clicking on attachments and links in their emails.
The message from the UK's National Crime Agency was "do not pay!" -
there is no guarantee that systems will be restored.
Michael Gazeley, of Network Box, a Hong Kong-based cyber-security firm,
told Reuters there were still "many 'landmines' waiting in people's
in-boxes", adding that his firm had detected a new version that infected
users directly via a malicious link on hacked websites.

Becky Pinkard, from Digital Shadows, a UK-based cyber-security firm,
also said it would be easy for the initial attackers or "copy-cat
authors" to change the virus code so it is difficult to guard against.
A UK security researcher known as "MalwareTech", who helped to limit the
ransomware attack, predicted "another one coming... quite likely on
Monday".
MalwareTech, whose name was revealed in UK media to be 22-year-old
Marcus Hutchins, was hailed as an "accidental hero" after registering a
domain name to track the spread of the virus, which actually ended up
halting it.
What's behind Microsoft's 'wake-up call' warning?
The computing giant says the tool used in this current attack had been
developed by the US National Security Agency and was stolen by hackers.
It is highly critical of the way governments store data on software
vulnerabilities.
Microsoft president and chief legal officer Brad Smith said on Sunday:
"We have seen vulnerabilities stored by the CIA show up on WikiLeaks,
and now this vulnerability stolen from the NSA has affected customers
around the world.
"An equivalent scenario with conventional weapons would be the US
military having some of its Tomahawk missiles stolen."
The organisation also said that many organisations had failed to keep
their systems up to date, allowing the virus to spread.
Microsoft said it had released a Windows security update in March to
tackle the problem involved in the latest attack, but many users were
yet to run it.
Analysis: Dave Lee, BBC North America technology reporter
There are going to be some tough questions on Monday for those
institutions which didn't do enough to keep their networks secure, as
well as the organisations that were best placed to stop it happening in
the first place - the NSA and Microsoft.
The NSA keeps a chest of cyber-weapons to itself so it can hit targets,
but Microsoft has long argued that this is dangerous. If there is a flaw
in Windows, the company said, surely the safest thing to do is to let
its team know straight away so it can be fixed.
But then Microsoft also needs to consider what obligation it has to
update all users - not just the ones who pay extra for security on older
systems.
Updating your computer if you're an individual is a piece of cake, but
for a network the size of Britain's National Health Service? Tough -
time-consuming, expensive and complex.
For a company like Microsoft to say it won't keep those systems safe
unless they shell out more money, then that in itself, I think, is
something of a ransom. |
