Zscaler Releases Semi-Annual Cloud Security Insights Report
Leader in Cloud Security Reveals 400% Increase in Phishing Attacks in 2018
As the use of SSL grows to the point where it’s the standard protocol, cybercriminals are increasingly using encryption to conceal and launch attacks. This has become possible because SSL certificates, which used to be difficult to obtain, are now readily available at no charge.
“With the ever-increasing concerns over data privacy, there has been a
massive trend toward Internet properties having encryption by default.
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

- Newly Registered Domains: Nearly 32 percent of newly registered domains that were blocked by the Zscaler™ cloud platform were using SSL encryption.
“One of the most notable SSL threat trends that we saw in 2018 was the
increase in JavaScript skimmer-based attacks. These attacks start with
the e-commerce sites being compromised and injected with malicious,
obfuscated JavaScript, which, in turn, tries to tap into purchase
transactions,” said Deepen Desai, Vice President of
