Malware via Removable Devices Nearly Doubles

Malware being delivered via removable media, such as USB drives, nearly doubled last year, according to a new report.

The report, The 2021 Honeywell Industrial USB Threat Report, found that some 37% of threats were designed to take advantage of removable media. Of those, according to the report, 79% could cause “significant disruption” to operations.

The report noted that USB usage was up 30% during 2020. Almost a third of threats were trojans. Slightly more than half of threats established remote access.

"USB-borne malware was a serious and expanding business risk in 2020, with clear indications that removable media has become part of the playbook used by attackers, including those that employ ransomware," said Eric Knapp, engineering fellow and director of cybersecurity research for Honeywell Connected Enterprise, in a prepared statement. "Because USB-borne cyber intrusions have become so effective, organizations must adopt a formal program that addresses removable media and protects against intrusions to avoid potentially costly downtime."

The full report is freely available via Honeywell’s site.
