As mentioned above, the Hacktool:Win32/Keygen tool allows users to "crack" (illegally register) various software. It simply forges activation keys/license files to trick programs into believing that they are activated. This tool itself is not harmful (other than it diminishes the revenue of software developers), but is often distributed together with viruses.

Generating and verifying license keys is a common requirement for a lot commercial softwarethese days. From desktop applications such as those built on frameworks like Electronor Qt, to dual-licensed open source packages and libraries like Sidekiq,to a variety of other on-premise software applications and dependencies.
When it comes to software licensing, the key generation and verification algorithms vendorschoose can make or break a licensing system. After an algorithm has been compromised, a vendorcan no longer trust any previously generated license keys, including those belonging to legitend-users.
Software cracks usually only work for a single version of a particular application, sincethe application code itself is modified to bypass any license checks (meaning a softwareupdate often requires an updated crack for the new application code.) Distributing acracked version of an application falls on the bad actor.
The other major attack vector is known as a software "keygen", which is much more ominous. Asits name may imply, a keygen is a form of software, often a separate program or webpage, thatgenerates valid license keys, i.e. a key-generator, or "keygen."
Depending on your key generation algorithm, a keygen like this may only be able to generate validkey for a single version of an application. But in the worst case, a bad actor can create a keygenthat generates valid license keys that work across all versions of an application, requiringa complete upheaval of the product's licensing system.
Partial Key Verificationis a software license key algorithm that partitions a product key into multiple "subkeys."With each new version of your product, your license key verification algorithm will check a differentsubset of a license's subkeys.
Our PKV keygen should be a tightly kept trade secret, because with it comes the power to craftlicense keys at-will. But we'll soon realize, much to our demise, keeping a PKV keygen secretis actually not possible.
If you notice, getSubkeyFromSeed(seed, 24, 3, 200) is deriving an expected 0th subkey from theseed value. We then compare the expected 0th subkey to our license key's actual 0th subkey. If thesubkeys don't match, the license key is not valid.
Well, at the end of this scenario, once all subkey parameters have been leaked, the bad actorcan fully replicate our secret keygen! (After all, we've literally given them the keys to ourcastle. It was a slow trickle, but they were patient.)
Some applications will have a central point in the bytecode where this check happens, but othersharden their system by inlining the license key checks, making the work of a bad actor wanting tocrack the software much, much harder. But licensing is all essentially the same: it's a seriesof conditionals.
When choosing a modern license key algorithm, we have a quite a few solid options. For example, ourAPI supports a variety of cryptographic schemes for license keys, from elliptic-curve signatures,to RSA signatures and even encryption. Today, we'll be covering elliptic-curve and RSA-2048 signatures.
The license keys we generate may differ in length, depending on the cryptographic scheme we use,but the format is going to stay the same: some encoded data, a delimiter ".", and a cryptographicsignature of the data. (This is more or less the same format our API uses for cryptographic keys.)
After generating our keypair, we're going to want to keep those encoded keys in a safeplace. We'll use the private signing key for our keygen, and we'll use the publicverify key to verify authenticity of license keys within our application.
One downside is that the more data you embed, the larger the license keys will become.But in the real world, this isn't really an issue, since the majority of users willcopy-and-paste their license keys, as opposed to typing them in by hand.
And as expected, like our keypair, our license keys are also much larger. But they'resecure. And remember, most users copy-and-paste, so length doesn't really matter.(You could even wrap license keys in a license.dat file, which makes distributiona breeze. But that's just an implementation detail.)
Once again, it takes less than 10 lines of code to verify license keys withinyour application. Our RSA implementation can be improved by using a more modernnon-deterministic padding scheme, PKCS1-PSS (which our API also supports.)
But remember, a crack != a keygen, so your application's licensing always runsthe risk of being circumvented via code modification. But license keys cannotbe forged when you utilize a licensing system built on modern cryptography.
Generating and verifying the authenticity of cryptographically signed license keyslike we've covered will work great for a lot of licensing needs. The implementationis straight forward, it's secure, and these types of license keys work especiallygreat for offline-first perpetual licenses (or a timed license with an embedded,immutable expiry).
We first note that the State offered ample evidence of appellant's guilt from sources independent of her statement. Dr. Booth's daughter testified that, six months prior to her death, Dr. Booth told her that "the black lady that lived across the alley" called her in the middle of the night and asked to borrow money. The victim's caller ID records showed that she received two calls from an anonymous number on July 22, 1997, at 6:19 a.m. and 6:29 a.m. Harry Wilkins, Jr., aka, "Smiley," testified that appellant was driving the victim's white Mercedes Benz station wagon when she met him on the morning of July 22, 1997, to inquire about buying crack cocaine. The State further showed that appellant pawned the victim's diamond ring on July 22, 1997, and that she used the victim's credit cards at several locations on July 23, 1997. When appellant was arrested on July 24, 1997, she attempted to take with her a tote bag containing the victim's driver's license and several of the victim's credit cards. The State's strongest independent evidence of appellant's guilt was produced when the police executed a search warrant at appellant's home on July 24, 1997. Officers found a large knife stained with Dr. Booth's blood in appellant's kitchen cabinet above the refrigerator. The bloody knife matched other knives found in the kitchen drawers of appellant's house.
Early Tuesday morning about 1:30 a.m., drugs were delivered to me at my residence by "Kilo" and "J.C.", two guys I met in South Dallas selling drugs, about a month or so ago. Both guys stayed at my residence & partied with me. After my money & the drugs ran out, they asked if I could get some more money. I told them no. They asked me if I knew any of my neighbors I could borrow money from & I said no, not at that hour & that I had to go to work. At that time they began to be verbally abusive & threatening to harm me if I didn't. I called my neighbor "Dorothy Booth". I'm not sure of the time & got no answer. I waited a while & called back, she answered. "Kilo" told me to hang up & I did. He told me to call back & ask her to borrow some sugar or milk instead of money over the phone, because they were going to rob her & take the car. I called back & asked to borrow sugar, she said ok. Kilo & J.C. followed me to her house, when she opened the door & saw me, to let me in they both pushed the door open & knocked her down. I was shoved back outside to her car. The driver side was unlocked & I was told to stay there & lay down in the front seat. Several minutes later they both came out with her car keys, purse, & CD player. Both guys went back into my house & came out with a jam box, cordless phone & caller ID. They told me to drive to Mi Amore motel on second avenue to make a pick up. I was told to park on the next street over & wait for them. After about 3-5 minutes or so I drove off with all the belongings they took & went to Fitzhugh to the dope house. No one answered the door so I went to Perry street dope house. I took everything out of the car & went inside to get dope. They didn't have any so "Smiley" said he would go around the corner & get me some. I gave him the keys & another girl rode with him. They came back & the police stopped them in front of the dope house on Perry street. I went to the back of the house & waited a few minutes & left out the back door to get drugs elsewhere. A few hours later I returned to Perry street dope house & "Smiley" was upset that the cops stopped him. He gave me the car keys back. He asked me if the car was stolen & I said no. He wanted to rent it out for dope so I did & left. After the dope ran out I searched the purse & found a diamond ring & credit cards. I took the ring to the pawn shop & sold it. Later I used the credit card at the grocery store & gas station to purchase cigarettes by the carton for resale at the "boot leg" for cash. I went to a friend's house to smoke dope. He sold the caller ID and cordless phone for dope money. The jambox was sold to an individual at the Mexican dude on Fitzhugh & East Grand. I got a ride with a male & female. We went to several gas stations & she went inside to use the credit cards once or twice. 041b061a72
