Palo Alto Networks Analyses Malware Attack Trends

New research from leading enterprise security provider Palo Alto Networks has looked into the current trends in malware attacks.

The survey – the Unit 42 Threat Landscape Review – has found that the Kuluoz or Asprox malware family is responsible for the majority of malware attacks on organisations.

The latest research performed by Palo Alto Networks’ threat intelligence team examined the affects on different industries, from healthcare to financial services, using data from Palo Alto’s threat intelligence cloud system WildFire.

The findings suggest that the primary channels for malware delivery are email (SMTP) and HTTP, but different industries are affected in varying amounts. For example, malware from web channel accounted for 28 per cent in retail and wholesale organisations, but only two per cent for hospitality organisations.

The Kuluoz or Asprox malware family was found to have been responsible for nearly 80 per cent of all attack sessions in October of this year. As much as 2,000 organisations were affected by attacks during this time. This malware has plagued Internet users for years, despite multiple attempts to disrupt its infrastructure.

Ryan Olson, intelligence director of Palo Alto Networks’ Unit 42 commented on the findings: "The trends we observe in the Threat Landscape Review indicate that malware attacks against industries such as finance, healthcare and critical infrastructure occur over similar channels but in significantly different proportions.”
