Attack is a card type. An Attack is a card intended to hinder the player's opponent(s), either by making their next turn worse in some way, or otherwise weakening their deck. However, not all Attacks are equal, and while some can be quite devastating, others can range from mildly annoying to borderline beneficial to other players, depending on the circumstances. Most Attack cards are Action cards. There are no special rules relating to Attack cards; they are simply a useful label to have so that other cards (mostly Reactions) can refer to them.

Attacks are often a crucial component of an engine strategy: an engine deck can take longer to build than an unimpeded Big Money deck; but an engine that frequently plays Attack cards can slow down an opponent's deck-building enough to make engine construction competitive. However, since they attack the opponent, strong Attack cards often have relatively weak (or even no) direct benefits to their owner's deck, slowing down deck-building from that direction as well.
Not every play of every Attack card will adversely affect (or even affect at all) an opponent, and some cards which can be used to hurt an opponent, such as Masquerade, Possession and Ill-Gotten Gains, are not Attacks. The fact that "Attack" is a card type becomes relevant in that certain cards have specified interactions with Attacks. Most of these are Reaction cards that can be revealed when an opponent plays an Attack to have some effect that usually mitigates or counters the adverse effect of the Attack. Other cards that have specific interactions with the Attack type include Squire, Urchin, and Battle Plan.
All Dominion expansions have at least two Attack cards. The greatest density of Attack cards is found in Cornucopia, which contains three Attack cards out of 13 Kingdom cards, as well as Followers, an Attack–Prize. The lowest density of Attack cards is in Renaissance, which has only two Attacks out of 25 Kingdom cards.
 Kinds of Attacks
There are 6 basic kinds of Attacks; some Attack cards belong to two of these categories. Donald X. Vaccarino explained 4 of them here in depth, including how to defend against them; the other two were speculated on here.
Some Attack cards from Nocturne, such as Skulk, invoke Hexes. The Hexes themselves are not Attacks (since they are not cards) but the Doom cards that invoke them against opponents are. Hexes have a range of possible effects, so an Attack such as Skulk may belong to different ones of these classes on different occasions.
 Handsize attacks
Handsize attacks reduce the number of cards you have in hand on your next turn, thus reducing the range of options available to you on that turn. The majority of these make you discard down to 3 cards, and the victim chooses which cards to discard; thus multiple plays of such handsize attacks don't hurt the victim more than the first one. These include cards like Militia. A few, like Clerk, instead force opponents to topdeck cards from their hand. Some only hit players above a certain handsize, such as Pillage. Some handsize attacks can make victims continue discarding cards on multiple plays, such as Torturer.
The strongest counters to most handsize attacks include Menagerie, which is more likely to grant +3 cards in smaller hands, Horse Traders, which increases your handsize again once your next turn starts, and draw-to-X cards like Cursed Village.
 Attacks that trash your cards
Trashing attacks usually trash one of the top two cards of the opponents' decks, directly combating their deck-building efforts. Donald X. Vaccarino has described it as challenging to create trashing attacks that aren't too random in their degree of effectiveness and don't totally ruin players' enjoyment of the game. This is accomplished in various ways: trashing can be restricted to Treasure cards, as in Bandit, or to a certain price range, as with Knights, or the Attack can offer the victim a replacement for the trashed card, as with Swindler. Cardinal exiles opponents' cards instead of trashing them, which makes it possible for the victim to restore the lost cards to their deck by gaining another copy.
Trashing attacks can often be countered with gainers.
 Attacks that give you junk
Attacks that add undesirable cards to opponents' decks hurt an opponent by weakening the turns on which they draw those "junk" cards, and by slowing their deck cycling. The majority of these, like Witch, distribute Curse cards and therefore are referred to as cursers; the on-gain effect of Ill-Gotten Gains has the same function as these Attacks, though it is not itself an Attack card. Dark Ages does not contain cursers; instead, its junking attacks are Looters which distribute Ruins. A few junkers, like Noble Brigand, can distribute Copper. Some, such as Ambassador, distribute a variety of junk cards, including Curses under some circumstances.
 Attacks that muck with your deck order
Deck order attacks attempt to ensure that weak cards are left on top of an opponent's deck, or strong cards are discarded, weakening their upcoming hands and denying them opportunities to play their best cards. Cards like Bureaucrat specifically try to put bad cards on the opponent's deck; cards like Rabble can make them discard whatever good cards are there while leaving bad cards behind.
 Attacks that make other players' turns worse
Turn-worsening attacks, though not addressed in his Guide to Beating Attacks, were mentioned by Donald X. in his Seaside preview. Until Adventures, there weren't really any Attacks that fit this category and not any others (obviously, a handsize Attack usually makes a player's turn worse). Attack-Durations and tokens make this category possible.
The main examples here are Bridge Troll and Enchantress; they don't make players discard, trash their cards, or give them junk, and they do nothing to their deck, but they certainly makes their turns worse. Relic also fits here (as well as Raid, though it is not an Attack); rather than making a player discard directly, it prevents players from drawing in the first place. This can either make their current turn worse if they have draw cards, or their next turn if they do not.
 Attacks that lower other players' score
The only Attacks that consistently lower opponents' scores in Dominion are cursers, though their effect as junking attacks is usually more important than the fact that Curses are worth negative victory points. Trashing attacks can lower scores if they hit a Victory card. One Hex (Misery) lowers scores directly, and Attack-Doom cards will eventually hit that one. Coven effectively just reduces other players' scores by 1VP per play unless/until the Curse pile empties. Donald X. has said he's tried cards that lower scores directly, e.g. like a reverse Monument, but they "fluctuated between being too weak, too strong, and too much work to deal with."
 Defending against Attacks
The most direct way to defend against an Attack is with a card that simply grants you immunity from attacks, if one is available. However, those cards are not always the most efficient way to protect yourself, and there sometimes exist other ways to mitigate the effects of certain types of attack. Handsize attacks can be handily combated by Menagerie or a draw-to-X card, junkers can be thwarted by a heavy-duty trasher or a protective Watchtower, trashing Attacks can be countered with gainers, and deck-order attacks can be mitigated by sifters. All of these are embodied in Jack of all Trades, which Donald X. has revealed he designed as an "after-the-fact Moat." A number of different counters to specific Attacks have also been found.
