Low-Grade Ways of Bypassing Email Scanners

Cybercriminals are replacing common words in phishing scams with synonyms in order to bypass security filters, according to researchers at Avanan. For example, one phishing lure contained a malicious file titled, “Remittance Advice,” instead of “invoice,” since many phishing emails contain the word “invoice,” and “invoice” is widely recognized as a word that flags a message as suspicious. Avanan says this technique was effective in fooling technical defenses in this case.
