Microsoft has opened the lid on a significant-scale phishing-as-a-assistance (PHaaS) procedure which is associated in selling phishing kits and electronic mail templates as very well as supplying web hosting and automated companies at a low value, therefore enabling cyber actors to obtain phishing strategies and deploy them with small initiatives.
“With over 100 obtainable phishing templates that mimic regarded models and products and services, the BulletProofLink operation is liable for numerous of the phishing strategies that affect enterprises now,” Microsoft 365 Defender Risk Intelligence Crew explained in a Tuesday report.
“BulletProofLink (also referred to as BulletProftLink or Anthrax by its operators in numerous internet sites, advertisements, and other promotional components) is utilized by a number of attacker groups in possibly one-off or month-to-month subscription-primarily based organization models, creating a regular income stream for its operators.”
The tech big said it uncovered the operation in the course of its investigation of a credential phishing campaign that used the BulletProofLink phishing package on either on attacker-managed internet sites or web-sites provided by BulletProofLink as component of their service. The existence of the operation was initially produced general public by OSINT Fans in Oct 2020.
Phishing-as-a-company differs from regular phishing kits in that unlike the latter, which are sold as one-time payments to obtain obtain to packaged files that contains ready-to-use e-mail phishing templates, they are membership-based and comply with a computer software-as-a-support design, while also growing on the capabilities to incorporate created-in website web hosting, e mail supply, and credential theft.
Thought to have been lively considering that at minimum 2018, BulletProofLink is regarded to run an on the internet portal to publicize their toolset for as substantially as $800 a month and permit cybercrime gangs to sign-up and shell out for the provider. Buyers can also avail of a 10% discount need to they decide to subscribe to their e-newsletter, not to mention spend anyplace between $80 to $100 for credential phishing templates that allow for them to steal credentials entered by unsuspected victims on clicking a malicious URL in the e mail concept.
Troublingly, the stolen credentials are not only sent to the attackers but also to the BulletProofLink operators utilizing a system called “double theft” in a modus operandi that mirrors the double extortion assaults used by ransomware gangs.
“With phishing kits, it is trivial for operators to incorporate a secondary area for qualifications to be sent to and hope that the purchaser of the phish package does not change the code to take out it,” the researchers stated. “This is correct for the BulletProofLink phishing package, and in conditions where the attackers utilizing the service obtained credentials and logs at the finish of a week in its place of conducting strategies by themselves, the PhaaS operator preserved management of all qualifications they resell.”
