Each character has a number of attacks to choose from, including a basic attack (page 287). The exact attacks you have available depend on which powers you select for your character (see Chapter 4).

MAKING AN ATTACK
All attacks follow the same basic process:
1. Choose the attack you’ll use. Each attack has an attack type.
2. Choose targets for the attack (page 272). Each target must be within range (page 273). Check whether you can see and target your enemies (page 273).
3. Make an attack roll (page 273).
4. Compare your attack roll to the target’s defense (page 274) to determine whether you hit or miss.
5. Deal damage and apply other effects (page 276).

Notice under making an attack it says ALL ATTACKS, thus if something does not follow the process it is not an attack.
[quote='PHB 274]To determine whether an attack succeeds, you make an attack roll.[/quote]
[quote='PHB 276]You resolve an attack by comparing the total of your attack roll (1d20 + base attack bonus + attack modifiers) to the appropriate defense score. If your roll is higher than or equal to the defense score, you hit. Otherwise, you miss.[/quote]
Bottom line, unless you make an attack roll against a target, you are not attacking. This creates some wierd things with powers like
Hunger of Hadar which is not an attack until it is sustained. But it is RAW and I believe it is also RAI...
