Ransomware continues to pose a "significant" threat, and email remains one of the top attack vectors being used by both criminals and nation-states, Australia's Cyber Security Center warns in its latest "Cyber Threat Report," which urges organizations to improve their defenses.
Hackers wielding Nefilim ransomware are targeting unpatched or poorly secured Citrix remote-access technology, then stealing data, unleashing crypto-locking malware and threatening to dump data to try to force payment, New Zealand's national computer emergency response team warns.

Rather than focusing solely on rankings offered by the common vulnerability scoring system, or CVSS, when setting priorities for risk mitigation, organizations need to size up the specific potential risks that vulnerabilities pose to their critical assets, according to a new report from RiskSense.
The city of Baltimore's ransomware outbreak - $18 million in costs and counting - led to many crypto-locked files being lost forever, because no IT policy mandated centralized file backups. But effective IT solutions exist to help solve this challenge, provided they're deployed in advance of an attack.
Email server alert: Linux and Unix administrators should immediately patch a remotely exploitable flaw in Exim, one of the world's most-used message transfer agents, security experts warn.
