"Cybercrime is an evolution, not a revolution," says Europol's Philipp Amann, who oversees the EU law enforcement intelligence agency's annual study of the latest cyber-enabled crime trends. Ransomware, social engineering and the criminal abuse of cryptocurrency and encryption are some of the top threats.
Microsoft and its partners are continuing to put pressure on the Trickbot malware operation, eliminating an estimated 94% of its infrastructure. But some security researchers warn that the botnet's operators are developing workarounds to re-establish its infrastructure, enabling the group to resume its activities.
VMware Carbon Black is out with its latest Global Incident Response Threat Report, which describes "the perfect storm" for increasingly sophisticated attacks heading into 2021. Cybersecurity strategist Tom Kellermann discusses what that means - and how these trends should inform our defensive strategies.
The recent "takedown" of Trickbot by Microsoft and others had only a temporary effect; the botnet's activity levels have already rebounded, according to Crowdstrike and other security firms.

Despite the takedown of the Trickbot botnet by Microsoft and others Monday, the malware is still functioning, and its operators retain the tools needed to rebuild their malicious network, some cybsersecurity experts say. So the impact, while significant, could prove to be temporary.
Ransomware attacks remain the top cyber-enabled threat seen by law enforcement. But phishing, business email compromises and other types of fraud - many now using a COVID-19 theme - also loom large, Europol warns in its latest Internet Organized Crime Threat Assessment.
