'Der Angriff' (the attack) is the noun for the verb 'angreifen' (to attack). The basic meaning of 'greifen' (to grab) and the prefix 'an-' (towards) is still recognizable in the idea of an attack.
Die Wölfe greifen das verletzte Tier an.
The wolves attack the injured animal.
The target of an attack is almost always expressed with the preposition 'auf' and the accusative. This structure applies to military, sports, and verbal attacks.
Die Hacker planten einen Angriff auf die Server der Bank.
The hackers planned an attack on the bank's servers.
There is a well-known saying: 'Angriff ist die beste Verteidigung' (attack is the best defense). It means that in a conflict situation, it is best to become active yourself instead of only reacting.
Anstatt zu warten, ging er zum Chef und sagte seine Meinung – Angriff ist die beste Verteidigung.
Instead of waiting, he went to the boss and said what he thought — attack is the best defense.
A verbal or written attack is often described more precisely with adjectives like 'persönlich' (personal), 'scharf' (sharp/harsh), 'verbal' (verbal), or 'direkt' (direct).
Das war ein unnötig scharfer Angriff auf seine Arbeit.
That was an unnecessarily harsh attack on his work.
In a medical context, 'Angriff' (attack) describes a sudden bout of an illness. It is often combined with the name of the illness, as in 'Asthma-Angriff' (asthma attack) or 'Panik-Angriff' (panic attack).
Bei einem Panik-Angriff kann die Atmung sehr schnell werden.
During a panic attack, breathing can become very fast.
criticism / review
'Kritik' and 'Angriff' can both refer to negative words about someone or something. 'Kritik' points out mistakes or weaknesses and can be meant objectively. An 'Angriff' is much harsher: it feels hostile and is often meant to hurt the other person or make them look bad. The words can be confused because harsh criticism can feel like an attack. If someone calmly says what is not good, 'Kritik' fits better. If the words are very aggressive or personal, 'Angriff' is more precise.

Sein Kommentar war kein normaler Hinweis mehr, sondern ein persönlicher Angriff.
His comment was no longer just a normal suggestion, but a personal attack.
Die Kritik der Kundin war klar, aber sie blieb freundlich.
The customer's criticism was clear, but she remained friendly.
