The WMC Global Threat Intelligence Team observed a noticeable escalation in targeted and sophisticated phishing campaigns throughout 2022, with a surge in SMS phishing and a decrease in campaigns featuring large corporations. Threat actors began to shift their focus to developing smish-to-vish campaigns — campaigns where threat actors use phone numbers in SMS messages as opposed to link-based phishing. In 2022, we also finally saw a move away from Covid-19 phishing lures as pandemic-related government funds and support stopped. Several new threat actors made an appearance in 2022 with prolific and novel campaigns explored below targeting banks and big name brands.

The latest US trend has seen threat actors moving from generic, wide-reaching phishing attacks using major banks as lures to targeted attacks featuring small credit unions. Although customers of financial institutions are the most common mark, there was a jump in threat actors specifically targeting credit union customers throughout the US, whereas in the UK a prevalent phishing campaign took advantage of the government-backed energy rebate scheme as energy prices peaked at an all-time high. As expected, big brands like Microsoft, Apple, Netflix, and PayPal were still targeted regularly throughout the year.

Since July 2021, WMC Global analysts have been tracking an emerging threat actor known as MRWEEBEE who is creating and selling phishing kits targeting customers of banks and credit unions in the United States. WMC Global threat analysts have been monitoring MRWEEBEE closely by investigating the threat actor’s tactics, techniques, and procedures (TTPs) found in their phishing kits. WMC Analysts paid close attention to how MRWEEBEE's kits collect personal identifiable information (PII), email credentials, banking details, payment information, and how they evade detection with extensive bot blocking.

In July, a report was released spotlighting a threat actor known as Robin Banks. WMC Global was also tracking this threat actor and noticed the scammer's attack infrastructure quickly went offline at the time of the article’s publication. It is possible this was done by the intel vendor or the threat actor trying to hide but may also have been an unknown party. Only a matter of weeks later, WMC Global analysts discovered Robin Banks was still operating and had rebuilt their backend phishing operation to be more resilient to takedowns, highlighting their awareness of the original article. 

Threat actors have found continuous success using package delivery services as SMS phishing lures since the start of the COVID-19 pandemic and package delivery phishing attacks are the number one harvester of credit cards that WMC Global is currently seeing. Scammers now gravitate towards any new courier as a lure because of the sheer effectiveness of the campaigns. These lures are often used to perform call back scams but consumers get wise to the same attack content, resulting in threat actors needing to diversify and increase their portfolio of campaigns. Introducing Evri, the latest UK courier company to be heavily targeted and brand abused for credential phishing attacks. 

On December 1^st, WMC Global encountered a large-scale email phishing campaign targeting Microsoft Office 365’s voicemail functionality. The email subject, “Voiceᴍᴀɪʟ,” uses several Latin characters in an attempt to bypass email filtering systems. The attack was live until December 4^th.

Phishing campaigns continue to utilize the disruption of the pandemic to target victims, and a new campaign takes advantage of Zoom's rising popularity. Since December, the "Compact" Campaign has been targeting thousands of users by impersonating a Zoom invite and is estimated to have collected over 400,000 Outlook Web Access and Office 365 credentials. This campaign is unique in its use of trusted domains to ensure delivery of phishing emails and preventing phishing pages from being blocked. This is especially worrisome for organizations who will struggle to defend against this attack.
