Although Apple makes a big song and dance about using their own silicon in iOS devices, as well as the T1 and T2 chips used in their MacBook Pro and iMac computers, they don't actually manufacture those chips. They're made by the Taiwan Semiconductor Manufacturing Company (TSMC). Over the weekend, TSMC was crippled by an outbreak of WannaCry, the highly virulent and damaging malware that caused widespread impact in May 2017.

Experts at a security round table event in Sydney yesterday said business owners are too focussed on what's going on now, inside their businesses, and not looking at outside threats. As a result, when events such as WannaCry and NoPetya strike, they are unprepared and get hit hard.

When the Petya/GoldenEye cyber event started about 48 hours ago, it looked like a more damaging upgrade to WannaCry. But as the dust settles it's becoming clear the makers and distributors of Petra/GoldenEye were not interested in money.

Today's release of security updates for Windows XP, Windows 8 and Windows 8.1 signals an about-face by Microsoft. In the wake of the WannaCry outbreak, the intention was to stem the spread of a virulent and damaging ransomware attack. But should the company keep patching an operating system that has been out of mainstream support for over eight years and extended support for three?

Following the recent WannaCry ransomware outbreak, Microsoft issued patches to the new unsupported Windows XP in order to rectify the vulnerabilities that WnnaCry exploited. Today, they have gone further issuing some further security patches as part of this month't Update Tuesday releases.

Mega breaches often garner the biggest headlines. Target in 2013 signalled the start of this, but since then we've seen Yahoo!, our own Red Cross Blood Bank, the US Department of Personnel Management and others suffer data exfiltration either by malicious parties or through human error. But something more troubling has been happening and it has me worried. Many of the protocols we rely on are under threat.

Earlier this week, I wrote about some analysis conducted by Symantec that suggested WannaCry was likely linked to threat actors from North Korea. But there's further evidence now that has people wondering what is really going on.

Symantec's researchers have uncovered a potential link between the WannaCry ransomware worm, that hit systems just over a week ago, and code used by the Lazarus Group, the hackers that attacked Sony in 2015 and $81M theft from the Bangladesh Central Bank and are believed to be based in North Korea.

With WannaCry garnering a lot of attention over the last few days, it's easy to forget that the root cause of the damage it wreaked is still out there. The vulnerability it exploited was a weakness in Windows' file-sharing protocol. And while the threat of WannCry has been largely contained, if the vulnerability, dubbed EternalBlue by the NSA, remains unpatched, it can be exploited by others. And that's something being identified in the wild.

Microsoft's President and Chief Legal Officer, Brad Smith, says this week's WannaCry attack "provides yet another example of why the stockpiling of vulnerabilities by governments is such a problem". And while Smith says Microsoft and other tech companies need to take the lead on combatting these widespread attacks, he highlights the shared responsibility required to protect, detect and respond to threats.

Krebs on Security reports that the WannaCry ransomware attack has netted the bad guys a total of just US$26,000. That might not sound like much, but it's probably a drop in the ocean compared to what it has cost businesses around the world.
