There is a man on instagam, who DM'd me claiming that there is a payroll situation going on and that if I do small tasks for him that he will add me on the payroll. All he needs is my mobile accounting log in and full name to add me to the pay roll. Is this a scam? It looks legit however I am still skeptical.
100% scam. Northern Trust is a major bank; they are not going to hire people via Instagram, nor pay them under the table, they will hire people via their website. And even if they were, they wouldn't need your bank account login; they would need your checking account number and routing number perhaps for direct deposit but not mobile banking. Northern Trust has over sixty jobs open right now on their website, so there's no reason to think there is an arbitrary limitation on hiring or similar which could cause someone to try and hire outside the regular boundaries - but even then, they are most certainly not going to do things this way as a major bank and one that will have a huge amount of regulatory oversight.
NOBODY, ever, should need your mobile account login and password. Even the bank itself should not ever request that or need it. Period, full stop.
