A new Python-primarily based hacking device known as FBot has been uncovered concentrating on web servers, cloud services, material management devices (CMS), and SaaS platforms this sort of as Amazon Web Services (AWS), Microsoft 365, PayPal, Sendgrid, and Twilio.
“Important options include credential harvesting for spamming attacks, AWS account hijacking applications, and features to allow attacks against PayPal and different SaaS accounts,” SentinelOne security researcher Alex Delamotte explained in a report shared with The Hacker Information.
FBot is the most recent addition to the record of cloud hacking instruments like AlienFox, GreenBot (aka Maintance), Legion, and Predator, the latter 4 of which share code-stage overlaps with AndroxGh0st.
SentinelOne explained FBot as “similar but distinct from these people,” owing to the actuality that it does not reference any source code from AndroxGh0st, whilst it exhibits similarities with Legion, which first came to mild very last calendar year.
The conclusion purpose of the resource is to hijack cloud, SaaS, and web solutions as very well as harvest qualifications to get hold of original obtain and monetize it by providing the obtain to other actors.
FBot, in addition to generating API keys for AWS and Sendgrid, packs an assortment of features to crank out random IP addresses, operate reverse IP scanners, and even validate PayPal accounts and the email addresses associated with individuals accounts.
“The script initiates the Paypal API ask for through the web-site hxxps://www.robertkalinkin.com/index.php, which is a Lithuanian manner designer’s retail revenue internet site,” Delamotte observed. “Interestingly, all identified FBot samples use this internet site to authenticate the Paypal API requests, and various Legion Stealer samples do as perfectly.”
On major of that, FBot packs in AWS-particular characteristics to check for AWS Uncomplicated Email Company (SES) email configuration particulars and establish the specific account’s EC2 service quotas. The Twilio-linked operation, similarly, is used to acquire specifics about the account, specifically the stability, currency, and phone figures linked to the account.
The characteristics really don’t stop there, for the malware is also able of extracting credentials from Laravel surroundings information.
The cybersecurity agency claimed it uncovered samples beginning from July 2022 to as lately as this month, suggesting that it is getting actively applied in the wild. That said, it is really at present not recognised if the tool is actively maintained and how it is really distributed to other players.
“We discovered indications that FBot is the product of personal advancement operate, so modern day builds could be dispersed by way of a smaller sized scale procedure,” Delamotte explained.
“This aligns with the concept of cloud attack equipment staying bespoke ‘private bots’ tailored for the specific consumer, which is a theme prevalent between AlienFox builds.”
