Phishing is on the up. 

A report published by Microsoft on 2019’s malware and cybersecurity trends revealed that phishing was one of the few attack vectors to have seen a rise in activity over the past two years.

According to the report, phishing attacks increased from less than 0.2% in January 2018 to around 0.6% in October this year. However, while phishing attacks grew, the number of ransomware, crypto-mining and other malware infections went down.

In a recent blog post, Microsoft revealed three of the smartest phishing attacks it has seen in 2019.

1. Hijacked search results

This multi-layered malware operation resulted in infected Google search results. Here’s how it worked:

·        The criminals funnelled web traffic from legitimate sites to websites under their control

·        The domains became top Google searches for specific terms

·        Victims received emails linking to the Google search result

·        If the victim clicked the link and then the top result, they landed on a gang-controlled website and were redirected to a phishing page

This was possible because rather than targeting high-traffic keywords, the attackers focused on gibberish (like “hOJoXatrCPy”), and used location-specific search results.

2. Abusing 404 error pages

Phishers also started using custom 404 pages to serve phishing sites. The attackers were using links that pointed to non-existent pages, so when Microsoft’s security systems scanned the link it was deemed safe (as it returned a 404 error). 

However, if a real user clicked on the URL, they would be redirected to a phishing page, not a 404 error page. By also using subdomain generation algorithms and regularly changing the main domain, attackers were able to generate almost unlimited phishing URLs.

3. MiTM-based phishing

Some phishing attacks incorporated a man-in-the-middle (MiTM) server, taking impersonation to another level. As Microsoft explains: “a man-in-the-middle component captured company-specific information like logos, banners, text, and background images from Microsoft's rendering site.” This resulted in “the exact same experience as the legitimate sign-in page, which could significantly reduce suspicion.” However, even though the login page looked perfect, the phishing site’s URL was still visible in the address bar.
