On-device threats jump 16.2% to 3.8 million in 2025

Malware spread via removable methods continues to persist.

Singapore saw on-device threats rise 16.2% year-on-year (YoY) to 3.8 million instances in 2025, according to data from Kaspersky.

Worms and file viruses accounted for the majority of the incidents, Kaspersky said in a press release in March 2026, based on the number of threats it detected and intercepted last year.

Malware spread via removable USB drives, CDs, DVDs, and other “offline” methods continue to persist and is rising in intensity across Singapore, it said.

On-device attacks can execute automatically once the removable medium is connected, according to Kaspersky, directly undermining the integrity of the host system and is harder to detect with traditional defenses.

Successful infection grants attackers extensive access to sensitive information stored on the device, such as private files, saved credentials, and system data, it warned.

A NOTE FROM SINGAPORE BUSINESS REVIEW

If you've been wondering whether SBR could work for your company — yes, probably.

A lot of the companies we partner with started as readers. They'd been following our coverage for a while, saw their own customers and competitors in it, and eventually asked the obvious question: could we do something with you? The answer is usually yes. The shape of it depends on what you're trying to do.


The options are broader than most people assume — thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. Some partners use one channel; most use a mix. We figure out the right combination by starting with your brief, not with our rate card.


So if the question has been on your mind, here's the easy way to ask it.

We'll tell you honestly whether we can help, and how. It's a better use of everyone's time.
