In the second half of 2021, adware exploded.
This is explored in depth in the Allot H2 2021 Cyber Threat Report.
The report found that, during the second half of 2021, Allot NetworkSecure blocked a total of 2.97 billion cyber threats for consumers who subscribe to Allot-powered cybersecurity services provided by European CSPs. That represents an increase of 574% compared to the first half of 2021. The two types of threats that made up the bulk of the blocks were Flubot C&C URLs and omnatuor.com, a very aggressive adware infection.
What happened in the threat landscape during the second half of 2021?
- 74% of all blocks were adware, making this threat category the primary menace to consumers.
- In September alone, there was an increase of 200% of total blocks due to the spread of omnatuor.com, which first appeared in the second half of 2021.
- Flubot is still active, with 421,905,856 threats blocked during H2 2021. Flubot has been very profitable for the cybercriminals who employ it to steal personal and financial data.
- Cybercriminals used Black Friday, Christmas, and the lottery as bait to trick victims. Allot NetworkSecure blocked millions of attempted phishing attacks during the reporting period.
While it may be tempting to get complacent about adware, this menace is more than a nuisance, as it can lead to the downloading additional malicious malware.
