The identity of the individual or group behind the global WannaCry ransomware campaign remains unclear. But whoever wrote the ransom notes appears to have been fluent in Chinese and pretty good at written English, according to a linguistic analysis from security firm Flashpoint.
In the wake of WannaCry, there's a critical new flaw in Samba, which provides Windows-based file and print services for Unix and Linux systems. Security experts say the flaw is trivial to exploit. US-CERT recommends immediate patching or workarounds.
A number of media reports have recently suggested there's a "link" between WannaCry and the Lazarus hacking group, implying that North Korea authorized the ransomware campaign. But based on the evidence available so far, it's much too early to attribute the attacks to anyone.
Target has reached a record settlement agreement with 47 states' attorneys general over its 2013 data breach. The breach resulted in hackers compromising 41 million customers' payment card details and contact details for more than 60 million customers being exposed.
The Donald Trump administration, in its fiscal 2018 budget, outlines steps it contends would strengthen the U.S. federal government's information systems, even as it would cut some cybersecurity spending at specific agencies.
The WannaCry ransomware outbreak showcases the problem: Security pros are overwhelmed by vulnerabilities that could be simple to mitigate, if only they had the right info at the right time. Humphrey Christian of Bay Dynamics discusses how to improve vulnerability risk management.
The WannaCry ransomware outbreak was a huge "wake-up call" for the global information security community, says Dan Schiappa of Sophos. It's time to patch those legacy systems and prepare for the inevitable next big crimeware scare, he says.
Voice biometrics: Is it good enough to protect people's bank accounts? Also, the ISMG Security Report goes to Belfast, Northern Ireland, for this year's OWASP AppSec Europe conference, including a visit to the Titanic museum - hopefully not a metaphor for the discipline.
Good news for many victims of WannaCry: Free tools developed by a trio of French security researchers can be used to decrypt some PCs that were forcibly encrypted by the ransomware, if the prime numbers used to build the crypto keys remain in Windows memory.
Sweden has ended a seven-year rape investigation against WikiLeaks founder Julian Assange. But it's far from the end of the legal troubles for the man whose spilling of secrets has shaped world politics.
WannaCry ransomware victims who haven't backed up their files have a tough choice: take a risk paying the ransom or just accept the loss. But there's a slim glimmer of hope: French researchers have figured out a way to decrypt files without paying, although their tools won't work for everyone.
