The victim did not see his attacker.

A woman was raped and presented with a series of photographs from which to identify her attacker.

This gives a tremendous advantage to the attacker, because the defender doesn't know who to fight back against.

You may plead that the attacker must possess a piece of information about the database schema in most examples.

Chinese tourist was beaten at Thai airport the attacker was fired and the president of the airport was removed from his post.

When the Soviet Union broke up, we effectively lost that adversary as a potential attacker of the United States, for the most part.

Facebook, which has more than 2.2 billion monthly users, said it had not determined whether the attacker had abused any accounts or stolen personal information.

For example, if an attacker had gleaned information about a page based on a prior form submission, they may attempt to override variables, or modify them

If approached from behind, Mizrachi says, the first thing to do is turn around, so that you can see your attacker and 'clear the line of fire'.

At the same time, put weight on the gun and punch the attacker in the chest, then twist the gun from his grip before backing up and pointing it at him.

First, no evidence yet exists that any of the Paris attackers actually came from Syria as refugees. The Syrian passport found near the body of one attacker appears to have been stolen.

When the illegal war against Iraq broke out, some of the most ardent defenders of the so called responsibility to protect decided to remain silent, while others allied themselves with the attacker.

Direct SQL Command Injection is a technique where an attacker creates or alters existing SQL commands to expose hidden data, or to override valuable ones, or even to execute dangerous system level commands on the database host.

A knee to the groin follows, and while the attacker doubles up in pain, you twist the gun from his hands, smack him in the face with the barrel and back up, keeping the weapon trained on him.

An unknown attacker may also be deterred by cyber security measures. If firewalls are strong, or redundancy and resilience allow quick recovery, or the prospect of a self enforcing response ( an electric fence ) seems possible, an attack becomes less attractive.

However, if we'd had this talk 60 years ago, we would have seen how the emergence of new aircraft and tank technologies, which give the advantage to the attacker, make the Blitzkrieg doctrine very credible and thus create the possibility of war in Europe.

But deterrence requires a credible threat of response against an attacker. And that becomes much more difficult in a world where governments find it hard to tell where cyber attacks come from, whether from a hostile state or a group of criminals masking as a foreign government.

There was also Gulnaz, a young woman who was jailed for adultery after being raped by a relative (she was recently released after a presidential pardon, but may be forced to marry her attacker). The husband of another young woman, Aisha, cut off her nose and ears when she ran away.

None of this is true in cyberspace where a weapon can consist of a few lines of code that can be invented (or purchased on the so called dark web) by any number of state or non state actors. A sophisticated attacker can hide the point of origin behind the false flags of several remote servers.

The reason that the electronic jellyfish worked as a lure is not because giant squid eat jellyfish, but it's because this jellyfish only resorts to producing this light when it's being chewed on by a predator and its only hope for escape may be to attract the attention of a larger predator that will attack its attacker and thereby afford it an opportunity for escape.

Now, another form of defense is something called a burglar alarm same reason you have a burglar alarm on your car the honking horn and flashing lights are meant to attract the attention of, hopefully, the police that will come and take the burglar away when an animal's caught in the clutches of a predator, its only hope for escape may be to attract the attention of something bigger and nastier that will attack their attacker, thereby affording them a chance for escape.
