Ransomware attacks are increasingly using multiple proven techniques to spread quickly and achieve the maximum impact before being thwarted. They are going to get bigger and target other platforms in the future, warns Justin Peters at Sophos APAC.
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.
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.
In the wake of the surge in business email compromise incidents, many organizations have implemented new anti-phishing controls. But the attackers are countering the counter-measures, says Agari's Wes Dobry. What is the best response?
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.
Many security leaders argue over whether their incident response posture needs to be proactive or reactive. But Rsam CISO Bryan Timmerman says it isn't either or - that organizations need both. Here's why.
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.
How can a supercomputer help enterprise security teams respond to today's evolving threat landscape? Martin Borrett of IBM and Ronan Murphy of Smarttech discuss the promise and impact of Watson for Cyber Security.
