Business Email Compromise (BEC) attacks have increased by a huge 80%, according to the latest quarterly ESRA report from Mimecast. This is compared to last year’s report which caught 41,605 impersonation emails.
In its inspection of over 142 million emails, Mimecast found 203,000 malicious links and what’s even more worrying is that more than 10 million were marked “safe” by other security vendors. That makes for a ratio of one unstopped malicious link for every 50 emails inspected. It’s clear that attacks are on the rise and current measures aren’t catching them.
BEC attacks have found ways around security systems. Across 19 million spam emails, 13,176 contained dangerous files and 15,656 had malware attachments that were all missed by security protection on the accounts.
Matthew Gardiner is the cybersecurity strategist at Mimecast and has this to say about the rise of attacks:
“Targeted malware, heavily socially-engineered impersonation attacks, and phishing threats are still reaching employee inboxes. This leaves organisations at risk of a data breach and financial loss. Our latest quarterly analysis saw a continued attacker focus on impersonation attacks quarter-on-quarter. These are difficult attacks to identify without specialised security capabilities, and this testing shows that commonly used systems aren’t doing a good job catching them.”
Now more than ever, users are being urged to enhance their cyber resilience and protection, helping to educate themselves and their employees of the dangers.
It is often beneficial for a cyber reliance strategy to have a multi-layered approach because a single layer of protection can be broken through.
