What we currently know about the global cyberattack

19 Mai 2017

Jonathan Levin of Chainalysis, which monitors bitcoin payments, said there were other differences compared to most ransomware campaigns: for instance the lack of sophisticated methods used in previous cases to convince victims to pay up.

No institution is immune from attempted ransomware attacks, but these measures can help avoid a successful attack or, at least, limit the resulting damage. By 10.30 am there were 68 payments totalling approximately $25,000.

"Identification usually occurs by linking the suspect's transactions to a bitcoin exchange, which would hold identifying information about their clients".

So if you or your employer has seen computers freeze up and demand illicit payment over the past few days, don't curse your fate.

An Australian entrepreneur a year ago stepped forward and claimed to be the founder of bitcoin, only to say days later that he did not "have the courage" to publish proof that he is. This map effectively shows the location of the malware's original spreading. One of the greatest benefits of using Bitcoin in online gambling is that it is very secure to use them.

As with everything on the blockchain, bitcoin wallets are transparent and openly visible, which is how it's known precisely how much money the attackers have managed to collect. Since this digital currency offers great benefits, it is becoming more and more popular every day.

Perhaps it is time for the United States to actually take meaningful action against Bitcoin.

"As far as we're aware this is how much they've made from this attack, although it is possible there are addresses we're not aware of", says Tom Robinson, co-founder of Elliptic, which works with law enforcement authorities to identify illicit activity involving bitcoin. If they ever do try to move the funds without taking appropriate precautions, they could get caught.

So what do you do if you receive the WannaCry ransomware message?

And thirdly, the way the ransomware is encrypting the files on a computer suggests it would be nearly impossible for the ransomware developers to decrypt them, even if they wanted to. But from each patient zero the software then spread through computer networks by itself.

There are, however, fears that WannaCry's true impact in the country could go under reported due to companies' reliance of unsupported or pirated versions of Microsoft Windows.

Then of course if the huge publicity over the attacks means the cryptocurrency becomes indelibly associated with criminals and suffering, the sign "Bitcoin Accepted Here" could well lose its trendy commercial appeal. Computers which do not have the latest Windows security updates applied are at risk of infection. Upgraded computers are no longer vulnerable.

Exercise caution when opening emails - and don't click on any attachments or links sent to you by an unknown sender.

Potential outcomes of a ransomware attack include inability to access data; financial repercussions related to responding to the attack; possible payment of a ransom; and loss of credibility as an educational institution.

Each victim is advised on where and how to pay the ransom in order to be released from the encryption. This way, if your machine gets encrypted, you needn't worry about losing your data. Also, there is no guarantee that your files or data will be returned safely.

WannaCry is formulated to ask for a ransom of $300 in the beginning, which would rise to $600, if the victim refuses to pay the ransom during the first 7 days following infection of his/her machine.

Bitcoin is well-entrenched as the preferred payment for cybercriminals like the WannaCry hackers who have hit more than 300,000 computers over the past week, but cryptocurrencies offering more anonymity are threatening to displace it.
