Sharper Point: Four takeaways from the WannaCry cyberattack

20 May 2017, 01:31 | Megan Pierce

"We know the NSA treasure trove is in bad guy's hands, why wouldn't they use it?"

The hospital also ensured that all of its security tools - Palo/Wildfire, Sophos, Open DNS, etc. - were updated with the newest tools, and that its security operations center had new use-cases built for monitoring any suspicious traffic or events, Prill said. The cyber attack was based on a ransomware known as WannaCry. Should they want to get their data back, users are asked to pay up large sums of money to get a decryption key. We can certainly question whether they are having much impact given the scale of the recent Ransomware attack. "We have not got any reports of widespread infection of the ransomware", she said.

Two additional variants of the WannaCry malware were patched versions - rather than recompiled versions from the original authors - according to Ryan Kalember, senior vice president of cybersecurity at Proofpoint, which helped stop the original strain of the virus last week. "Someone at the other end of the connection", Hickey said. "At $300 per ransom the potential payoff of even a small percentage of hundreds of thousands of compromised machines could be significant".

Under former President Barack Obama, the USA government created an inter-agency review, known as the Vulnerability Equities Process, to determine whether flaws should be shared or kept secret.

"While it would be satisfying to hold accountable those responsible for this hack - something that we are working on quite seriously - the worm is in the wild, so to speak, at this point, and patching is the most important message as a result", said Bossert. It took advantage of a vulnerability in Windows that allowed it to infect PCs.

"That means it's not just coming in through email".

French carmaker Renault said its plant in the northern town of Douai would not reopen on Monday as it dealt with the cyber-attack. "Following this, Microsoft had sent patches in its update in March itself to counter this particular form of threats", Udhav told TNM. Security is a hard-to-evaluate feature against a possible future threat, and consumers have long rewarded companies that provide easy-to-compare features and a quick time-to-market at the expense of protection.

However, there was no official information in this regard from the RBI in this connection till late evening.

"Ransomware in particular relies on locking up files, so our advice to organisations if you have a reliable backup, this is less of an issue - noting the malware needs to be neutralised first". And that may account for why systems are left vulnerable.

The VNCERT said the ransomware is extremely unsafe as it is capable of stealing information and decrypting the entire system that has been infected.

"By prioritizing clinical functionality and uptime, healthcare organizations may not always have the most up-to-date software".

As MalwareTech noted in a blog post afterward, the ransomware was written to connect to an unregistered domain and "if the connection is not successful it ransoms the system, if it is successful the malware exits". Instructions on how to install this patch are also available at ZDNet.

Affected Windows systems include everything from Windows Vista, Windows Server 2008, Windows 7, Windows 8.x, Windows Server 2012, Windows 10 and Windows Server 2016. One of the leaked Central Intelligence Agency attack tools targets internet-enabled Samsung smart televisions.

Using trademark garbled English, the Shadow Brokers group said in an online statement that, from June, it will begin releasing software to anyone willing to pay for access to some of the tech world's biggest commercial secrets.
