Cyber adversaries are resilient and move quickly, so it'st critical that organizations share threat intelligence in an automated way, says Shawn Henry of CrowdStrike Services. But that sharing has been hampered by a lack of understanding of why it's important and how organizations can benefit, he says.
Attackers exploiting a buffer overflow in WhatsApp's signaling software to automatically infect devices with malware - without users even having to answer their phone - and then alter call logs to hide attack traces is "a bit of a nightmare scenario," says cybersecurity expert Alan Woodward.
Microsoft says intruders targeting its email services had access to email content for a single-digit percentage of the overall affected accounts, a more serious conclusion than first thought. But the company hasn't released many details, including the total number of accounts affected.
Email remains the top threat vector for organizations. And while the move to cloud-based solutions has significantly improved email security, environments such as Office365 have their own complexities that need to be addressed, says David Wagner, CEO of Zix Corp.
Hackers have breached the Australian Parliament's network, although investigators say they have found no evidence that attackers stole any data. But Parliament's presiding officers said all users have been ordered to reset their passwords as a precaution.

Data science is playing a fundamental role in a more dynamic approach to cybersecurity, says Jim Routh, CISO of Aetna, who stresses the importance of applying machine learning to front-line data security controls. Routh will be a featured speaker at the ISMG Security Summit in New York Aug. 14-15.
To better counter threats carried by content - email, attachments, files - Deep Secure's Simon Wiseman says organizations should investigate content threat removal, which involves extracting required data from content and discarding the rest.
Europe's General Data Protection Regulation is reshaping the way organizations handle data. That's going to have an impact on the sharing of threat intelligence. But the Anti-Phishing Working Group hopes the law will provide legal clarity that will make more organizations comfortable with sharing threat data.
