NotPetya was not as bad as WannaCry, despite NotPetya being even more sophisticated, and targeting the same EternalBlue flaw that had allowed WannaCry to spread far and fast. Microsoft says NotPetya's builders limited its attack capabilities by design.
With the exception of one large theft incident involving an insider, hacker attacks - including some involving ransomware - continue to be the leading culprits in the biggest health data breaches reported so far this year. What's next?
Like in the recent WannaCry attacks, the U.S. healthcare sector has so far mostly avoided becoming a victim of NotPetya, the malware menacing many organizations across the globe. Who had been affected so far?
As the WannaCry outbreak demonstrated, many organizations run outdated operating systems. Too often when systems - and especially embedded devices - still function, there isn't a convincing business case for upgrading. ESET's Mark James asks: Whose fault is that?
When malware comes gunning for your national health service, you're going to take it personally. And that's just one reason why the WannaCry outbreak in particular boosted cybersecurity awareness in the U.K. and around the world, says Barracuda's Hatem Naguib.
As the count of NotPetya victims grows, Ukraine warns that it's also being targeted with a new WannaCry lookalike that hit state power distributor Ukrenergo. Security researchers say that marks the fourth recent campaign targeting Ukraine that's based on lookalike ransomware.
The latest edition of the ISMG Security Report leads with an analysis exploring how artificial intelligence can be used by hackers to threaten IT systems and by organizations to defend critical digital assets. Also, a deep dive into the NotPetya ransomware attack.
Deducing intent from malware code is tricky, but computer security experts appear to agree that the latest wave of file-encrypting malware was never designed to make its creators rich. Instead, it's intended to destroy disks.
Malware known as NotPetya, SortaPetya or GoldenEye continues to spread globally, infecting endpoints via leaked Equation Group exploits as well as built-in Windows tools. Here's a roundup of what we know about the supposed ransomware and its spread so far.
The Cyber Threat Alliance is developing playbooks that will show organizations how to stop hackers from causing havoc. Alliance President Michael Daniel explains how the playbook could help to disrupt a cyber attacker's business model and processes.
Is Petya worse than WannaCry? The second global outbreak of file-encrypting malware in as many months sees cyberattackers having designed potent, rapidly spreading malicious code far faster than organizations have been shoring up their defenses.
A massive, global ransomware outbreak has been hitting airports, banks, shipping firms and other businesses across Europe and beyond. Security experts say the apparent Petya variant appears to spread in part by exploiting the "EternalBlue" SMB flaw in Windows, previously targeted by WannaCry.
With massive profits available to criminals who can infect PCs and servers and extract a ransom, it's no surprise that attacks involving crypto-locking ransomware continue to increase. Security experts say such attacks are increasingly driven by ransomware-as-a-service programs.
A Google security researcher has once again found a potentially devastating vulnerability in Microsoft's Malware Protection Engine, the core component of anti-malware systems that ship with every Windows computer and server.
