A growing percentage of cyberattacks are using encryption to avoid detection, according to a new report by Zscaler’s ThreatLabZ researchers. Their report, summarized by Help Net Security, highlights the ways attackers are making security platforms work much harder to identify malicious activity. Last year, Zscaler’s platform detected and blocked 2.7 million encrypted phishing attacks per month. It also found that 32 percent of newly-registered, potentially malicious domains were using SSL certificates.
“With the ever-increasing concerns over data privacy, there has been a massive trend toward Internet properties having encryption by default,” said Zscaler’s Chief Technology Officer Amit Sinha. “This is a great thing for privacy, but it presents a challenge to IT security. Decrypting, inspecting, and re-encrypting traffic is nontrivial, causing significant performance degradation on traditional security appliances, and most organizations are not equipped to inspect encrypted traffic at scale.”
In total, Zscaler blocked 1.7 billion attacks executed over SSL between July and December of 2018. “With a high percentage of threats now delivered with SSL encryption, and over 80 percent of Internet traffic now encrypted, enterprises are blind to over half of malware sent to their employees,” Sinha continued. The use of encryption for these attacks allows malicious activity to take place without victims knowledge.
Security platforms are fighting an uphill battle to keep up with the tactics used by attackers. New-school security awareness training is an essential complement to technical defenses, because it can enable your employees to identify any malicious activity that slips through the cracks.
