Mac-based malware has appeared on the list of the top ten most common types of malware for the first time in WatchGuard’s quarterly Internet security report. The Mac scareware appeared in sixth place in WatchGuard’s latest Q3 2018 report and is primarily delivered by email to trick victims into installing fake cleaning software.
Researchers also found that 6.8 percent of the world’s top 100,000 websites still accept old, insecure versions of the SSL encryption protocol, while more malware hits were seen in Asia Pacific than in any other geographical region, reflecting a significant increase in attacks targeted at this area throughout 2018.
“Outside of a few surprising finds, like Mac scareware in our top ten malware list, we saw attackers stick to what they know in Q3 by reusing and modifying old attacks like cross-site scripting, Mimikatz and cryptominers. It’s a good reminder that the vast majority of attacks aren’t ultra-advanced zero-days and can be prevented by using a layered security approach with advanced malware detection capabilities and investing in secure Wi-Fi and MFA solutions,” said Corey Nachreiner, CTO at WatchGuard Technologies. “However, we are quite concerned at how many major websites are still using the insecure SSL protocol. This is a basic security best practice that should be implemented across 99.9 percent of the internet by now – it puts hundreds of thousands of users at risk.”
The top takeaways from the Q3 2018 report include:
- 6.8 percent of the top 100,000 websites still support old, insecure versions of the SSL protocol. Despite it being deprecated by the Internet Engineering Task Force (SSL 2.0 was deprecated in 2011 and SSL 3.0 in 2015), 5,383 websites in the top 100,000 via Alexa still accept SSL 2.0 and SSL 3.0 encryption. Also, 20.9 percent of the top 100,000 websites still do not use web encryption at all.
- Mac malware cracks the top ten for the first time ever. A piece of Mac scareware appeared in sixth place in WatchGuard’s top ten malware list. It is primarily delivered by email and tries to trick victims into installing fake cleaning software.
- Hackers target APAC. For the second time ever, APAC reported more total malware hits than EMEA or the USA. Top variants included Razy, which targeted APAC almost exclusively, Win32/Heur and MAC.OSX.AMCleanerCA.
- Cryptominers remain popular. Razy, the second most common piece of malware detected by WatchGuard, evolved into a cryptominer in Q3 and made up 4 percent of all malware blocked by WatchGuard antivirus service worldwide.
- Mimikatz remains the most popular malware in Q3. This popular password theft kit has dominated WatchGuard’s top ten malware list for multiple quarters and shows no sign of slowing down.
- Attackers go after web applications with cross-site scripting. Cross-site scripting accounted for 39.3 percent of the top ten exploits in Q3, primarily targeting web applications.
