RAW: Yes, the wolf would be able to detect you, find you and attack you, but they would still have the blinded condition and therefore suffer all the effects of that condition (see below).
But the big takeaway is. If everyone (attacker and defender) is blinded, then it doesn't matter anyway, as attacking a blinded creature nets you advantage. And any advantage cancels any and all disadvantage.
You could likely make a Dexterity (Stealth) check if you want to actively avoid the wolves in the darkness, by moving quietly, but since they have keen hearing AND smell, it probably isn't worth it for you to waste an action on it. This is where it gets into RAI. As a DM, I might let you make a Dexterity (Stealth) check as part of a move action to remain still enough to not be heard, but that's a DM call.
PHB pg 183 - Vision And Light:
Relevant sections italicised
Darkness creates a heavily obscured area. Characters face darkness outdoors at night (even most moonlit nights), within the confines of an unlit dungeon or a subterranean vault, or in an area of magical darkness.
A heavily obscured area–such as darkness, opaque fog, or dense foliage–blocks vision entirely. A creature effectively suffers from the blinded condition (see appendix PH-A) when trying to see something in that area.

Blinded
- A blinded creature can't see and automatically fails any ability check that requires sight.
- Attack rolls against the creature have advantage, and the creature’s attack rolls have disadvantage.
pg 305 On The senses of wolves
Keen Hearing and Smell. The wolf has advantage on Wisdom (Perception) checks that rely on hearing or smell.
And finally, and perhaps most importantly on pg 177
NOTE: The hiding rules and the invisibility rules are effectively the same now, with the exceptions noted below.
Hiding When you try to hide, make a Dexterity (Stealth) check. Until you are discovered or you stop hiding, that check's total is contested by the Wisdom (Perception) check of any creature that actively searches for signs of your presence. You can't hide from a creature that can see you. and if you make noise (such as shouting a warning or knocking over a vase), you give away your position. An invisible creature can't be seen, so it can always try to hide. Signs of its passage might still be noticed, however, and it still has to stay quiet.
In combat, most creatures stay alert for signs of danger all around, 50 if you come out of hiding and approach a creature, it usually sees you. However, under certain circumstances, the Dungeon Master might allow you to stay hidden as you approach a creature that is distracted, allowing you to gain advantage on an attack before you are seen.
