The Australian Cyber Security Center (ACSC) strongly advises against paying ransoms of any amount to cybercriminals. In some circumstances, these payments could even be illegal. The Australian government is tightening its cybersecurity regulations to align with the United State's new stance on nation-state threats. As a result, there have been significant changes to how Australian businesses are expected to respond to cyberattacks.

Phishing schemes are always evolving. This past year, email thread hijacking took phishing to new depths of subterfuge as criminals hid in plain sight within existing conversations.

Ransomware prevention measures such as securing your applications can help you avoid becoming the next target. Ransomware isn’t a new problem—not even close. It’s been around for more than 30 years. But like every element of technology, it has evolved. Instead of being an occasional expensive nuisance, it’s now a plague with existential implications for critical infrastructure—energy, transportation, food supply, water and sewer services, healthcare, and more.

AT&T Alien Labs has observed the Mirai variant botnet, known as Moobot, scanning for known but uncommon vulnerabilities in Tenda routers, resulting in a considerable peak in our internal telemetry. The research associated with this peak resulted in the discovery of a malware hosting domain, providing several different Mirai variants, like Moobot and Satori.

The head of the UK’s National Cyber Security Centre has warned that ransomware has become the biggest threat to British people and businesses. In a speech being given today by Lindy Cameron, chief executive of the NCSC, to the RUSI think tank, she highlights the need for ransomware problem to be taken seriously, and warns of the “cumulative effect” if society fails to properly deal with the rising threat.
