Levels of email spam hit 12-year low

Has it felt like the amount of spam in your inbox has decreased of late? According to research by Symantec, the percentage of spam emails has dropped below 50% for the first time in over a decade.

Symantec's 'June 2015 Intelligence Report' reveals that, for the first time in 12 years, levels of spam emails have dropped to below 50% to 49.7%, down 1.8% since May this year.

Out of 704 billion email messages analyzed by Symantec in June, 353 billion were identified as spam. The decline has continued into July with just 46.4% of the 25 billion emails monitored by Symantec identified as spam.

Legal action against those who pipe spam to inboxes has helped deter spammers, and network providers have improved blocking and filtering methods.

Symantec's report also reveals that phishing attacks have decreased, from over a third to just around a quarter of all spam.

However, the news isn't all good - 57.6 million new malware variants were created in June, up from 44.5 million created in May and almost twice as many as in April (29.2 million).

Ransomware attack has also increased for the second month in a row and crypto-ransomware has reached its highest levels since December 2014.

"This increase in activity lends more evidence to the idea that, with the continued drops in email-based malicious activity, attackers are simply moving to other areas of the threat landscape," said Ben Nahorney in the report.
