It has been discovered that a new phishing campaign is being run using Microsoft Sway, which has been found by researchers. A series of attacks have been called the "Quishing" campaign to describe what is happening. The practice of "squishing" is a form of phishing that uses QR codes to lead people to malicious websites. An example of Quishing is embedding malicious URLs into a QR code to commit phishing.
A few groups of victims in Asia and North America are primarily focusing on the campaign. In late December, researchers noticed that an unexpected spike in traffic to unique Microsoft Sway phishing pages arose as a result of a campaign called "quishing," which targeted Microsoft Office credentials.
As defined by Netskope Threat Labs, quishing is essentially phishing to trick users into opening malicious pages by presenting them with QR codes, which are commonly used in many forms of phishing.
According to a spokesperson for the campaign, the campaign mainly targets victims in Asia and North America, across multiple industries such as the technology, manufacturing, and finance sectors.
A researcher from the University of California, Davis, reported that "attackers instruct their victims to scan QR codes with their mobile devices, in the hope that these portable devices do not possess the strict security measures found on corporate-issued devices," according to an article written by the researchers.
This QR phishing campaign utilizes two techniques that have been discussed in previous articles: transparent phishing in conjunction with Cloudflare Turnstile"
Those who operate phishing websites use Cloudflare Turnstile to ensure that their malicious websites are protected from static analysis tools so that they can hide their malicious payloads, prevent web filtering providers from blocking their domains, and maintain a clean reputation among the web community.
This is known as an attack-in-the-middle phishing technique, which is more sophisticated than traditional phishing techniques. The attackers not only attempt to gain access to the victims' credentials but also attempt to log them into the legitimate service using those credentials, bypassing multi-factor authentication, so they can steal sensitive tokens or cookies which can be used to gain further unauthorized access to the system.
This is a massive QR code phishing campaign, which abused Microsoft Sway, a cloud-based tool for creating presentations online, to create landing pages that scammed Microsoft 365 users into handing over their credentials in exchange for money.
According to Netskope Threat Labs, these attacks were spotted in July 2024 after detecting an increase of 2,000-fold in attacks exploiting Microsoft Sway to host phishing pages that allegedly steal access credentials for Microsoft 365 accounts.
Interestingly, this surge of activity dates back to the first half of the year when minimal activity was reported. So, it comes as no surprise that this campaign has been so widespread.
Essentially, they were interested in targeting users in Asia and North America, concentrating primarily on the technology, manufacturing, and finance sectors, which were the most likely to present themselves to them. A free application, called Sway, is available in Microsoft 365 for anyone with a Microsoft account who has a Microsoft account.
Attackers, however, utilize this open access as an opportunity to fool users by misrepresenting them as legitimate cloud applications, thus defrauding them of the money they are paid to use them. Furthermore, Sway is accessed once an individual logs into their Microsoft 365 account, adding a layer of legitimacy to the attack, since it is accessible once the victim has already logged into the account, thus increasing the chances of them opening malicious links.
Netskope Threat Labs identified a new QR code phishing campaign in July 2024, marking a significant development in cyber threats. This campaign primarily targets victims in Asia and North America, affecting various sectors, including manufacturing, technology, and finance.
Cybercriminals employ diverse sharing methods, such as email, links, and social media platforms like Twitter, to direct users to phishing pages hosted on the sway. cloud.Microsoft domain.
Once on these pages, victims are prompted to scan QR codes that subsequently lead them to malicious websites.
Microsoft Sway, a platform known for its versatility, has been exploited in the past for phishing activities. Notably, five years ago, the PerSwaysion phishing campaign leveraged Microsoft Sway to target Office 365 login credentials. This campaign, driven by a phishing kit offered through a malware-as-a-service (MaaS) operation, was uncovered by Group-IB security researchers.
The attacks deceived at least 156 high-ranking individuals within small and medium-sized financial services companies, law firms, and real estate groups. The compromised accounts included those of executives, presidents, and managing directors across the U.S., Canada, Germany, the U.K., the Netherlands, Hong Kong, and Singapore.
This escalation in phishing tactics highlights the ongoing battle between cybercriminals and cybersecurity professionals, where each defensive measure is met with a corresponding offensive innovation.
The need for a comprehensive approach to cybersecurity has never been more apparent, as malicious actors continue to exploit seemingly innocuous technologies for nefarious purposes. With the rising popularity of Unicode QR code phishing techniques, security experts emphasize the importance of enhancing detection capabilities to analyze not just images but also text-based codes and other unconventional formats used to deceive users and infiltrate systems. This sophisticated phishing method underscores the continuous vigilance required to safeguard digital environments against increasingly cunning cyber threats.
