Did you know, spam attacks increased by 400% in the past 12 months? Do you know what spam is and when you are likely to be hit by it?
This year alone, almost 44% of spam messages contained a malicious attachment according to the IBM X-Force Threat Intelligence Index, and around 85% of malicious spam attachments delivered ransomware!
TechRepublic have recently collated information from a study by IBM and found the following on when, where and how spammers attack:
- Spammers are most active on Tuesdays, followed by Wednesdays and Thursdays. This is likely because Tuesdays are a key day for email marketing, with 20% more opens than average, according to HubSpot. They are the least active on Mondays and Fridays.
- More than 83% of all spam is sent during weekdays, with significant drops on weekends.
- Spam messages hike around 1 am ET, and drop around 4 pm ET, because spammers start off with targets in Europe before moving to those in the US.
- In terms of location, the top originator of spam in the past six months was India, followed by South America and China.
Spammers have grown increasingly sophisticated, and studying trends around spamming is “an essential part of threat intelligence and situational awareness for any organization,” according to the report.
