Oc Technology — Fraud job threats

Because of the ongoing situation i am having some financial issues due to which i decided to start online work from home types jobs. So i start searching in quikr and got call from oc technology and gave company name as oc technologies. She said its an easy job and i only need to type captchas and will be paid upon completion of the work. For registration they asked me a copy of adhaar card and one photograph. Which i uploaded while completing the online form and later on they send me a agreement. While searching about company i found this is a fraudulent company and blackmailing people on basis of that agreement. Please advise and help me at the earliest.
I am already going through a tough time because of financial issues. Now i am afraid what if they start blackmailing me and ask me for money. Please help.
