2023.06.09 09:24 TopCucumber6288 Okus obratnega inženiringa - naloga 3
![]() | Pozdravljeni, submitted by TopCucumber6288 to HackProtectSlo [link] [comments] izvorna koda te naloge se nahaja na https://pastebin.com/MA89468T (geslo: slohackprotect). Kodo prevedemo enako kot pri nalogi 1. Naloga 1: LINK Naloga 2: LINK Obratni inženiring Tako kot pri nalogi 1, binarno datoteko najprej spustimo čez program strings, ki nam tokrat najde nekaj kar zgleda kot geslo - niz N0t4P4ssw0rd. Vendar geslo ne deluje. Nadaljujemo tako, da binarno datoteko uvozimo v Ghidro, kot smo to storili pri nalogi 2. Osredotočimo se na funkcijo main. https://preview.redd.it/333f3wuuvx4b1.png?width=333&format=png&auto=webp&s=f1fe2bbd7990860e5a2f243edfddd9e11a8f27a2 Opazimo, da se naš vnos ne primerja z nizom, ki smo ga našli z orodjem strings, ampak z nizom, shranjenim na naslovu, kamor kaže spremenljivka local_18. Ta spremenljivka je definirana v vrstici 18, kjer na kopici (angl. heap) ustvarimo prostor za 13 znakov. Nato program pokliče funkcijo decode, ki niz N0t4P4ssw0rd modificira in shrani na kopico na to mesto. Sedaj imamo 2 možnosti:
Program poženemo z gdb debuggerjem. Jaz uporabljam še dodatek pwndbg ( https://github.com/pwndbg/pwndbg) https://preview.redd.it/u2kfi0otxx4b1.png?width=976&format=png&auto=webp&s=16550f3953f5ea3b8f25aa623a2903c686b015c3 Postavimo breakpoint na začetek funkcije main in poženimo program. pwndbg> b * main Breakpoint 1 at 0x1285 pwndbg> r Starting program: /home/kali/Desktop/RE/example3 ... https://preview.redd.it/4yrd2mrbyx4b1.png?width=1002&format=png&auto=webp&s=990120bf934e76124a5e8f755b46720f23686f5b Na vrhu (RAX,RBX...) je seznam registrov in njihove vrednosti. Na sredini je prikazano, kje v programu se nahajamo, spodaj pa vidimo vrh sklada (angl. stack). Z ukazom next (krajše n) se začnemo premikati čez funkcijo main in opazujemo spremembe v registrih in na skladu. Če gdbju ne podamo ukaza, se ponovno izvede zadnji podani ukaz. Najprej podamo ukaz "n", nato pa samo pritiskamo enter. https://preview.redd.it/gtdm5jx2zx4b1.png?width=937&format=png&auto=webp&s=7a83cc7ccab59ea73d3bf64bb705817969d92ef1 S premikanjem čez funkcijo main dosežemo vrstico "call [email protected]", ki od nas zahteva, da vpišemo geslo. Vpišemo recimo "test" in pritisnemo enter. Nadaljujemo z izvajanjem funkcije main do vrstice "call malloc", ki bo na kopici rezervirala prostor. To vrstico še izvedeno in se nato ustavimo. https://preview.redd.it/2i2frmxwzx4b1.png?width=933&format=png&auto=webp&s=f5cdf3b52a66010b826c7340da933c6325ac90af Rezultat klica malloc, nam vrne naslov na kopici, kamor bo funkcija decode kasneje shranila dekodiran niz. Rezultat funkcije je shranjen v registru RAX. V našem primeru je malloc naredil prostor na naslovu 0x555555559ac0. Ta naslov si zapišemo in nadaljujemo z izvajanjem do vrstice, kjer pokličemo funkcijo decode. Takoj po tej vrstici se ustavimo in pogledamo na naslov, ki smo si ga zapisali. pwndbg> x/s 0x555555559ac0 0x555555559ac0: "N/v1T/yl#'Y"Kot pričakovano nas na tem naslovu pričaka dekodiran licenčni ključ, s katerim se uspešno vpišemo v program. $ ./example3 Enter security key: N/v1T/yl#'Y Access granted!Tokrat smo si ogledali osnove dinamične analize, spoznali smo, da če tudi je nek niz v sami izvorni kodi zakodiran, ga v neki točki program dekodira za primerjavo in ta trenutek izkoristimo mi. Lep pozdrav! |

2023.06.09 05:25 JoshAsdvgi THE RESUSCITATION OF THE ONLY DAUGHTER
![]() | submitted by JoshAsdvgi to Native_Stories [link] [comments] THE RESUSCITATION OF THE ONLY DAUGHTER There once lived an old couple who had an only daughter. She was a beautiful girl, and was very much courted by the young men of the tribe, but she said that she preferred single life, and to all their heart-touching tales of deep affection for her she always had one answer. That was "No." One day this maiden fell ill and day after day grew worse. All the best medicine men were called in, but their medicines were of no avail, and in two weeks from the day that she was taken ill she lay a corpse. Of course there was great mourning in the camp. They took her body several miles from camp and rolled it in fine robes and blankets, then they laid her on a scaffold which they had erected. (This was the custom of burial among the Indians). They placed four forked posts into the ground and then lashed strong poles lengthwise and across the ends and made a bed of willows and stout ash brush. This scaffold was from five to seven feet from the ground. After the funeral the parents gave away all of their horses, fine robes and blankets and all of the belongings of the dead girl. Then they cut their hair off close to their heads, and attired themselves in the poorest apparel they could secure. When a year had passed the friends and relatives of the old couple tried in vain to have them set aside their mourning. "You have mourned long enough," they would say. "Put aside your mourning and try and enjoy a few more pleasures of this life while you live. You are both growing old and can't live very many more years, so make the best of your time." The old couple would listen to their advice and then shake their heads and answer: "We have nothing to live for. Nothing we could join in would be any amusement to us, since we have lost the light of our lives." So the old couple continued their mourning for their lost idol. Two years had passed since the death of the beautiful girl, when one evening a hunter and his wife passed by the scaffold which held the dead girl. They were on their return trip and were heavily loaded down with game, and therefore could not travel very fast. About half a mile from the scaffold a clear spring burst forth from the side of a bank, and from this trickled a small stream of water, moistening the roots of the vegetation bordering its banks, and causing a growth of sweet green grass. At this spring the hunter camped and tethering his horses, at once set about helping his wife to erect the small tepee which they carried for convenience in traveling. When it became quite dark, the hunter's dogs set up a great barking and growling. "Look out and see what the dogs are barking at," said the hunter to his wife. She looked out through the door and then drew back saying: "There is the figure of a woman advancing from the direction of the girl's scaffold." "I expect it is the dead girl; let her come, and don't act as if you were afraid," said the hunter. Soon they heard footsteps advancing and the steps ceased at the door. Looking down at the lower part of the door the hunter noticed a pair of small moccasins, and knowing that it was the visitor, said: "Whoever you are, come in and have something to eat." At this invitation the figure came slowly in and sat down by the door with head covered and with a fine robe drawn tightly over the face. The woman dished up a fine supper and placing it before the visitor, said: "Eat, my friend, you must be hungry." The figure never moved, nor would it uncover to eat. "Let us turn our back towards the door and our visitor may eat the food," said the hunter. So his wife turned her back towards the visitor and made herself very busy cleaning the small pieces of meat that were hanging to the back sinews of the deer which had been killed. (This the Indians use as thread.) The hunter, filling his pipe, turned away and smoked in silence. Finally the dish was pushed back to the woman, who took it and after washing it, put it away. The figure still sat at the door, not a sound coming from it, neither was it breathing. The hunter at last said: "Are you the girl that was placed upon that scaffold two years ago?" It bowed its head two or three times in assent. "Are you going to sleep here tonight; if you are, my wife will make down a bed for you." The figure shook its head. "Are you going to come again tomorrow night to us?" It nodded assent. For three nights in succession the figure visited the hunter's camp. The third night the hunter noticed that the figure was breathing. He saw one of the hands protruding from the robe. The skin was perfectly black and was stuck fast to the bones of the hand. On seeing this the hunter arose and going over to his medicine sack which hung on a pole, took down the sack and, opening it, took out some roots and mixing them with skunk oil and vermillion, said to the figure: "If you will let us rub your face and hands with this medicine it will put new life into the skin and you will assume your complexion again and it will put flesh on you." The figure assented and the hunter rubbed the medicine on her hands and face. Then she arose and walked back to the scaffold. The next day the hunter moved camp towards the home village. That night he camped within a few miles of the village. When night came, the dogs, as usual, set up a great barking, and looking out, the wife saw the girl approaching. When the girl had entered and sat down, the hunter noticed that the girl did not keep her robe so closely together over her face. When the wife gave her something to eat, the girl reached out and took the dish, thus exposing her hands, which they at once noticed were again natural. After she had finished her meal, the hunter said: "Did my medicine help you?" She nodded assent. "Do you want my medicine rubbed all over your body?" Again she nodded. "I will mix enough to rub your entire body, and I will go outside and let my wife rub it on for you." He mixed a good supply and going out left his wife to rub the girl. When his wife had completed the task she called to her husband to come in, and when he came in he sat down and said to the girl: "Tomorrow we will reach the village. Do you want to go with us?" She shook her head. "Will you come again to our camp tomorrow night after we have camped in the village?" She nodded her head in assent. "Then do you want to see your parents?" She nodded again, and arose and disappeared into the darkness. Early the next morning the hunter broke camp and traveled far into the afternoon, when he arrived at the village. He instructed his wife to go at once and inform the old couple of what had happened. The wife did so and at sunset the old couple came to the hunter's tepee. They were invited to enter and a fine supper was served them. Soon after they had finished their supper the dogs of the camp set up a great barking. "Now she is coming, so be brave and you will soon see your lost daughter," said the hunter. Hardly had he finished speaking when she entered the tent as natural as ever she was in life. Her parents clung to her and smothered her with kisses. They wanted her to return home with them, but she would stay with the hunter who had brought her back to life, and she married him, becoming his second wife. A short time after taking the girl for his wife, the hunter joined a war party and never returned, as he was killed on the battlefield. A year after her husband's death she married again. This husband was also killed by a band of enemies whom the warriors were pursuing for stealing some of their horses. The third husband also met a similar fate to the first. He was killed on the field of battle. She was still a handsome woman at the time of the third husband's death, but never again married, as the men feared her, saying she was holy, and that any one who married her would be sure to be killed by the enemy. So she took to doctoring the sick and gained the reputation of being the most skilled doctor in the nation. She lived to a ripe old age and when she felt death approaching she had them take her to where she had rested once before, and crawling to the top of the newly erected scaffold, wrapped her blankets and robes about her, covered her face carefully, and fell into that sleep from which there is no more awakening. |

2023.06.09 03:06 Own-Heart-7217 Potential Matches UP-10604 Marietta, Georgia to MP-12599 Belinda Norred or MP-58311 Cindy Winn Powers
![]() | submitted by Own-Heart-7217 to gratefuldoe [link] [comments] Belinda Belinda Marietta, GA. Doe For Reference- Belinda Frances Norred – The Charley Project The UP was found in June, 1993. Belinda went missing 8/6/92 I believe the entire face "fits". In particular her cheeks. I have the same cheeks. Whatever physical markers the UP was able to give are similar to Belinda's. Belinda's truck was found in a Macon shopping center parking lot. Probably, not far from the UP. I don't have the address of the shopping center to verify this. Oddly the Namus listing on Belinda gives shoes and jewelry description but no clothing description. The UP description of the body has clothing and a pair of beaded inexpensive earrings, but no shoes, other jewelry or purse. The boyfriend was seen with some of Belinda's jewelry she always wore. He pawned the jewelry and was in possession of a gun Belinda carried in her purse. If her boyfriend was the last to see her, he described her jewelry & shoes which was what he took. Why did he not remember her clothing?Dentals- I have nothing to compare. It is a 20 minute drive (about 13 miles) to the mobile home park where Belinda lived to where the body was found. The UP, was located 5.8 miles from where her boyfriend had his listed address. All online articles from the Macon Telegraph regarding this case have been removed. Her boyfriend died in 2013. What I found odd was how close the UP & MP were geographically, and it has not been ruled out. I did submit this to the Namus representative and also sent an email to the sheriff. I heard back from the Namus rep representative: "Thank you for your submissions, we appreciate your time and support. NamUs staff will review the submitted information. Please note, identification and exclusions are only made and/or confirmed by investigating agencies. The results of comparisons may or may not be made available to the public for investigatory reasons." Unidentified Person Case (namus.gov) #10604 Missing Person Case (namus.gov) Belinda's Namus #2 I have a backup or what I would consider a second place. She was also located close to the UP and has not been ruled out. I informed the same people. (A while you were at it type of thing.) MP-58311 Cindy Win Power She went missing 34 minutes away from where the body was found (24 miles away) on New Year's Day 1989. She also matches the physical characteristics of UP-10604. Cindy Cindy UP again so you don't need to go back to the top. From the photo, she likes halter tops like the UP. I think her cheeks are also pronounced like Belinda and the UP. She has not been compared. UP-10604, Belinda nor Cindy have comparisons on Namus or any other sites known to me. Unidentified Person Case (namus.gov) #10604 Missing Person Case (namus.gov) Cindy Namus ETA PMI of UP is not stated. |
