Safe Browsing During a Pandemic: How to Spot COVID-19 Phishing Campaigns

Online bad actors tend to take advantage of tragedy for their own gain – and the coronavirus is no different.

When we investigate compromised websites, it’s not unusual to find malicious files that have been obfuscated through forms of encoding or encryption — however, these are not the only methods that attackers use to obfuscate code.
