Skimmer

Authors: Bassem Youssef & Bader Youssef Author's Note:  This article was originally posted on the IoDLT's blog, which fortunately, is mine :) I was seated in the chair of my local bank, excitedly awaiting to open a new bank account. As I was handed my new VISA debit card on the spot, I imagined the convenience that a powerful electronic payment solution would bring. Upon giving me the drill on my new card, the first words out of the bank manager’s mouth were: “Whatever you do, never use this debit card at the local gas pumps!” That’s right — I wasn’t allowed to utilize the convenience of my card at one of the simplest and seemingly harmless actions one can participate in. She told me that there was a serious problem concerning the pumps — one which had affected herself as well. I leaned forward in my chair out of curiosity, anticipating the reason as to why I wasn’t allowed to utilize my supposedly secure bank card. The reason for this dire warning was actually quite simple — and shocking. Many of the gas station pumps in the area were known to be compromised with an illegal credit card logging device known as a “skimmer”. In the last year, the number of skimmers in the state of Florida rose by 27.6 percent. In South Florida alone, nearly 200 skimmers were found in gas pumps. When you take into account the amount of traffic that each pump gets, especially in more populous places, the threat this issue poses becomes much more significant. With 29 million Americans pumping gas with credit cards everyday, and an estimated amount of $1 million dollars worth of fraud per skimmer, this is a disruptive issue that needs serious technological intervention. Shocking amount of skimmers found in Florida over the last year - source, WPTV How do credit card skimmers work? First things first — how do these things work? Most prominent in the states of Florida and Texas, Credit card skimmers are devices that are placed near the gas pump’s legitimate card reader. Frequently part of organized crime operations, they are often placed on the inside of the gas pump’s cabinet. The devices then log this data wirelessly over Bluetooth or even a cellular GSM connection, where criminals obtain the credit card information. Due to the wireless nature of the skimmer, the criminal never needs to return to the pump to retrieve their skimmer. Chip-based card readers are also in trouble; in the last year, devices known as “shimmers” have made their way into gas pump cabinets. These operate on the same principle as the skimmer, only they intercept card information from the supposedly secure chip-based card readers. To combat this issue, many gas stations began placing “security seals” to indicate if a pump has been tampered with. However, these stickers are easily replaceable once taken off, as the criminal can simply order a pack of 500 stickers for $69 USD online, making it not a very effective method for informing the public. Security seals do not aid in anti-skimming — they are easily replaceable How can NEM Catapult and IoT solve this? So, how can one solve this growing crime that affects millions of people in Florida and elsewhere? The answer lies with the NEM Catapult blockchain. We battle a high-tech problem with a high-tech solution! The use of blockchain (a distributed, trusted online ledger), with elements of Internet of Things (IoT), can aid in authenticating and auditing gas pumps and their activities. For this application, we can utilize the NEM Catapult blockchain, as it introduces several built-in mechanisms that will perfectly suite this application. To solve this issue, a low-cost IoT “anti-skimming” device is placed within each gas pump’s cabinet. This device will be equipped with a door sensor and smart lock. This is able to log who, when, where, and which gas pump was opened and (possibly) tampered with. In order to identify if the operator is certified or not, each IoT device would also utilize an RFID (radio frequency identification) tag to authenticate the person opening the gas pump cabinet. This authentication is done on the Catapult blockchain via two steps: Firstly, the operator that scans the pump’s RFID tag must own a non-transferable token (called a mosaic in NEM) on the Catapult blockchain. This token is a corporate or goverment-issued token, meaning this person would have to be a certified operator in order to own this token. Each of these tokens are placed under a Catapult “namespace”, which uniquely identifies the entity who issued the certification token. Each namespace on Catapult can only be owned by one entity, which verifies the legitimacy of the certification. For example, if the sender of the certification token is “shell-usa”, you can be certain that the operator was certified by Shell USA, and thus, is allowed to operate and open the pumps. Operator authentication using NEM Catapult mosaics Secondly, the gas station must also enter into a one-time, timed disposable smart contract (called an Aggregate Bonded contract) that grants the operator a window of time to perform the necessary, legitimate maintenance. If both the operator and gas station owner sign this smart contract, the IoT device will make note of this on-chain. This smart contract will signify that the operator has indeed shown up and interacted with the cabinet with the gas station owner’s approval within the allotted amount of time. One-time on-chain smart contract - called an Aggregate Bonded Transaction in NEM Once this authentication process is complete, the IoT device logs the full interaction directly on the blockchain as a valid event between the certified operator and the gas pump. If an individual was unable to complete the above steps, the device will log this interaction as “invalid”, notifying the gas station owner and prompting for further investigation on that specific pump. A concept mobile app that customers could use to discern whether a particular pump is trustworthy or not. On the left, a safe pump is shown. On the right, a pump may contain a skimmer. The blockchain will keep a verifiable ledger of the events of each gas station, and subsequently, each gas station pump as well. This also makes it more difficult for anyone attempting to gain illicit access to the pumps. Because each pump is now audited, customers can now verify the history of the pump by scanning the RFID tag, which will indicate whether the pump has been tampered with before. Crisis averted! Conclusion Utilizing blockchain and IoT will enable businesses to not only protect gas pumps from skimmers, but also other critical equipment that requires authorized and certified operators. Internet of Things is a very powerful tool that can simultaneously create conveniences for us while helping combat crime and improve quality of life. NEM Catapult’s easy-to-use API layer makes the communication of IoT devices a breeze, and guarantees a high level of security throughout the entirety of the solution.

A Treatise on Domestic Economy; For the Use of Young Ladies at Home and at School by Catharine Esther Beecher, is part of the HackerNoon Books Series. You can jump to any chapter in this book . ON THE CARE OF THE KITCHEN, CELLAR, AND STOREROOM. here CHAPTER XXXII. ON THE CARE OF THE KITCHEN, CELLAR, AND STOREROOM. If parents wish their daughters to grow up with good domestic habits, they should have, as one means of securing this result, a neat and cheerful kitchen. A kitchen should always, if possible, be entirely above ground, and well lighted. It should have a large sink, with a drain running under ground, so that all the premises may be kept sweet and clean. If flowers and shrubs be cultivated, around the doors and windows, and the yard near them be kept well turfed, it will add very much to their agreeable appearance. The walls should often be cleaned and whitewashed, to promote a neat look and pure air. The floor of a kitchen should be painted, or, which is better, covered with an oilcloth. To procure a kitchen oilcloth as cheaply as possible, buy cheap tow cloth, and fit it to the size and shape of the kitchen. Then have it stretched, and nailed to the south side of the barn, and, with a brush, cover it with a coat of thin rye paste. When this is dry, put on a coat of yellow paint, and let it dry for a fortnight. It is safest to first try the paint, and see if it dries well, as some paint never will dry. Then put on a second coat, and at the end of another fortnight, a third coat. Then let it hang two months, and it will last, uninjured, for many years. The longer the paint is left to dry, the better. If varnished, it will last much longer. A sink should be scalded out every day, and occasionally with hot ley. On nails, over the sink, should be hung three good dish-cloths, hemmed, and furnished with loops; one for dishes not greasy, one for greasy dishes, and one for washing pots and kettles. These should be put in the wash every week. The lady who insists upon this, will not be annoyed by having her dishes washed with dark, musty, and greasy, rags, as is too frequently the case. Under the sink should be kept a slop-pail; and, on a shelf by it, a soap-dish and two water-pails. A large boiler, of warm soft water, should always be kept over the fire, well covered, and a hearth-broom and bellows be hung near the fire. A clock is a very important article in the kitchen, in order to secure regularity at meals. On Washing Dishes.
No item of domestic labor is so frequently done in a negligent manner, by domestics, as this. A full supply of conveniences, will do much toward a remedy of this evil. A swab, made of strips of linen, tied to a stick, is useful to wash nice dishes, especially small, deep articles. Two or three towels, and three dish-cloths, should be used. Two large tin tubs, painted on the outside, should be provided; one for washing, and one for rinsing; also, a large old waiter, on which to drain the dishes. A soap-dish, with hard soap, and a fork, with which to use it, a slop-pail, and two pails for water, should also be furnished. Then, if there be danger of neglect, the following rules for washing dishes, legibly written, may be hung up by the sink, and it will aid in promoting the desired care and neatness. Rules for Washing Dishes. Scrape the dishes, putting away any food which may remain on them, and which it may be proper to save for future use. Put grease into the grease-pot, and whatever else may be on the plates, into the slop-pail. Save tea-leaves, for sweeping. Set all the dishes, when scraped, in regular piles; the smallest at the top. Put the nicest articles in the wash-dish, and wash them in hot suds, with the swab or nicest dish-cloth. Wipe all metal articles, as soon as they are washed. Put all the rest into the rinsing-dish, which should be filled with hot water. When they are taken out, lay them to drain on the waiter. Then rinse the dish-cloth, and hang it up, wipe the articles washed, and put them in their places. Pour in more hot water, wash the greasy dishes with the dish-cloth made for them; rinse them, and set them to drain. Wipe them, and set them away. Wash the knives and forks, being careful that the handles are never put in water; wipe them, and then lay them in a knife-dish, to be scoured. Take a fresh supply of clean suds, in which, wash the milk-pans, buckets, and tins. Then rinse and hang up this dish-cloth, and take the other; with which, wash the roaster, gridiron, pots, and kettles. Then wash and rinse the dish-cloth, and hang it up. Empty the slop-bucket and scald it. Dry metal teapots and tins before the fire. Then put the fireplace in order, and sweep and dust the kitchen. Some persons keep a deep and narrow vessel, in which to wash knives with a swab, so that a careless domestic cannot lay them in the water while washing them. This article can be carried into the eating-room, to receive the knives and forks, when they are taken from the table. Kitchen Furniture.
Crockery. Brown earthen pans are said to be best, for milk and for cooking. Tin pans are lighter, and more convenient, but are too cold for many purposes. Tall earthen jars, with covers, are good to hold butter, salt, lard, &c. Acids should never be put into the red earthen ware, as there is a poisonous ingredient in the glazing, which the acid takes off. Stone ware is better, and stronger, and safer, every way, than any other kind. Iron Ware. Many kitchens are very imperfectly supplied with the requisite conveniences for cooking. When a person has sufficient means, the following articles are all desirable. A nest of iron pots, of different sizes, (they should be slowly heated, when new;) a long iron fork, to take out articles from boiling water; an iron hook, with a handle, to lift pots from the crane; a large and small gridiron, with grooved bars, and a trench to catch the grease; a Dutch oven, called, also, a bakepan; two skillets, of different sizes, and a spider, or flat skillet, for frying; a griddle, a waffle-iron, tin and iron bake and bread-pans; two ladles, of different sizes; a skimmer; iron skewers; a toasting-iron; two teakettles, one small and one large one; two brass kettles, of different sizes, for soap-boiling, &c. Iron kettles, lined with porcelain, are better for preserves. The German are the best. Too hot a fire will crack them, but with care in this respect, they will last for many years. Portable furnaces, of iron or clay, are very useful, in Summer, in washing, ironing, and stewing, or making preserves. If used in the house, a strong draught must be made, to prevent the deleterious effects of the charcoal. A box and mill, for spice, pepper, and coffee, are needful to those who use these articles. Strong knives and forks, a sharp carving-knife, an iron cleaver and board, a fine saw, steelyards, chopping-tray and knife, an apple-parer, steel for sharpening knives, sugar-nippers, a dozen iron spoons, also a large iron one with a long handle, six or eight flatirons, one of them very small, two iron-stands, a ruffle-iron, a crimping-iron, are also desirable. Tin Ware. Bread-pans, large and small pattypans, cake-pans, with a centre tube to insure their baking well, pie-dishes, (of block-tin,) a covered butter-kettle, covered kettles to hold berries, two sauce-pans, a large oil-can, (with a cock,) a lamp-filler, a lantern, broad-bottomed candlesticks for the kitchen, a candle-box, a funnel or tunnel, a reflector, for baking warm cakes, an oven or tin-kitchen, an apple-corer, an apple-roaster, an egg-boiler, two sugar-scoops, and flour and meal-scoop, a set of mugs, three dippers, a pint, quart, and gallon measure, a set of scales and weights, three or four pails, painted on the outside, a slop-bucket, with a tight cover, painted on the outside, a milk-strainer, a gravy-strainer, a colander, a dredging-box, a pepper-box, a large and small grater, a box, in which to keep cheese, also a large one for cake, and a still larger one for bread, with tight covers. Bread, cake, and cheese, shut up in this way, will not grow dry as in the open air. Wooden Ware. A nest of tubs, a set of pails and bowls, a large and small sieve, a beetle for mashing potatoes, a spad or stick for stirring butter and sugar, a bread-board, for moulding bread and making pie-crust, a coffee-stick, a clothes-stick, a mush-stick, a meat-beetle to pound tough meat, an egg-beater, a ladle for working butter, a bread-trough, (for a large family,) flour-buckets, with lids to hold sifted flour and Indian meal, salt-boxes, sugar-boxes, starch and indigo-boxes, spice-boxes, a bosom-board, a skirt-board, a large ironing-board, two or three clothes-frames, and six dozen clothes-pins. Basket Ware. Baskets, of all sizes, for eggs, fruit, marketing, clothes, &c.; also chip-baskets. When often used, they should be washed in hot suds. Other Articles. Every kitchen needs a box containing balls of brown thread and twine, a large and small darning needle, rolls of waste-paper and old linen and cotton, and a supply of common holders. There should also be another box, containing a hammer, carpet-tacks, and nails of all sizes, a carpet-claw, screws and a screw-driver, pincers, gimlets of several sizes, a bed-screw, a small saw, two chisels, (one to use for buttonholes in broadcloth,) two awls, and two files. In a drawer, or cupboard, should be placed, cotton table-cloths, for kitchen use, nice crash towels, for tumblers, marked, T T; coarser towels, for dishes, marked, T; six large roller-towels; a dozen hand-towels, marked, H T; and a dozen hemmed dish-cloths, with loops. Also, two thick linen pudding or dumpling-cloths, a gelly-bag, made of white flannel, to strain gelly, a starch-strainer, and a bag for boiling clothes. In a closet, should be kept, arranged in order, the following articles: the dust-pan, dust-brush, and dusting-cloths, old flannel and cotton for scouring and rubbing, sponges for washing windows and looking-glasses, a long brush for cobwebs, and another for washing the outside of windows, whisk-brooms, common brooms, a coat-broom or brush, a whitewash-brush, a stove-brush, shoebrushes and blacking, articles for cleaning tin and silver, leather for cleaning metals, bottles containing stain-mixtures, and other articles used in cleansing. ON THE CARE OF THE CELLAR.
A cellar should often be whitewashed, to keep it sweet. It should have a drain, to keep it perfectly dry, as standing water, in a cellar, is a sure cause of disease in a family. It is very dangerous to leave decayed vegetables in a cellar. Many a fever has been caused, by the poisonous miasm thus generated. The following articles are desirable in a cellar: a safe, or moveable closet, with sides of wire or perforated tin, in which cold meats, cream, and other articles should be kept; (if ants be troublesome, set the legs in tin cups of water;) a refrigerator, or large wooden box, on feet, with a lining of tin or zinc, and a space between the tin and wood filled with powdered charcoal, having at the bottom, a place for ice, a drain to carry off the water, and also moveable shelves and partitions. In this, articles are kept cool. It should be cleaned, once a week. Filtering jars, to purify water, should also be kept in the cellar. Fish and cabbages, in a cellar, are apt to scent a house, and give a bad taste to other articles. STOREROOM.
Every house needs a storeroom, in which to keep tea, coffee, sugar, rice, candles, &c. It should be furnished with jars, having labels, a large spoon, a fork, sugar and flour-scoops, a towel, and a dish-cloth. Modes of destroying Insects and Vermin.
Bed-bugs should be kept away, by filling every chink in the bedstead with putty, and, if it be old, painting it over. Of all the mixtures for killing them, corrosive sublimate and alcohol is the surest. This is a strong poison. Cockroaches may be destroyed, by pouring boiling water into their haunts, or setting a mixture of arsenic, mixed with Indian meal and molasses, where they are found. Chloride of lime and sweetened water will also poison them. Fleas. If a dog be infested with these insects, put him in a tub of warm soapsuds, and they will rise to the surface. Take them off, and burn them. Strong perfumes, about the person, diminish their attacks. When caught between the fingers, plunge them in water, or they will escape. Crickets. Scalding, and sprinkling Scotch snuff about the haunts of these insects, are remedies for the annoyance caused by them. Flies can be killed, in great quantities, by placing about the house vessels, filled with sweetened water and cobalt. Six cents worth of cobalt is enough for a pint of water. It is very poisonous. Musquitoes. Close nets around a bed, are the only sure protection at night, against these insects. Spirit of hartshorn is the best antidote for their bite. Salt and water is good. Red or Black Ants may be driven away, by scalding their haunts, and putting Scotch snuff wherever they go for food. Set the legs of closets and safes in pans of water, and they cannot get at them. Moths. Airing clothes does not destroy moths, but laying them in a hot sun does. If articles be tightly sewed up in linen, and fine tobacco be put about them, it is a sure protection. This should be done in April. Rats and Mice. A good cat is the best remedy for these annoyances. Equal quantities of hemlock, (or cicuta,) and old cheese, will poison them, but this renders the house liable to the inconvenience of a bad smell. This evil, however, may be lessened, by placing a dish, containing oil of vitriol poured on saltpetre, where the smell is most annoying. Chloride of lime and water is also good.

ON THE CARE OF THE KITCHEN, CELLAR, AND STOREROOM.

"There is nothing new that is not old." Technological progress does not stand still, and neither do fraud methods. Not long ago, a by Akamai about a new technique for skimming. , where it all started, and what new fraudsters have invented will be discussed in our article. report was published Skimming Magecart: What Kind of Skimming Is That? Skimming is a fraudulent technique where criminals steal information from bank cards. In the early stages, criminals would install specialized card readers and overlay keypads on bank terminals to later clone the cards. Skimmers come in two types: some gather information from various users, while others immediately transmit card data to fraudsters through a radio channel or via an embedded SIM card over cellular networks. However, with the advancement of technology, this type of fraud has shifted to the Internet. Criminals inject malicious code into websites, typically on payment processing pages or other areas where users enter sensitive information, such as bank card details. Subsequently, when visitors enter their details on infected pages, criminals intercept this information. This technique is known as Magecart. Attackers seek out susceptible payment processing websites and insert malicious code into payment processing pages or other pages where customers enter bank card information. When information is entered, the malicious code intercepts it and transfers it to a remote server. Magecart has carried out several high-profile attacks on well-known e-commerce sites and third-party payment providers. The stolen data is usually sold on the underground market or used for fraudulent transactions. Regular security audits, website software updates, suspicious activity monitoring, and using security precautions security measures to identify and thwart such assaults are all part of the defense against Magecart attacks. There are known incidents in history involving companies such as Macy's, Puma, and British Airways. What's up with the 404? The skimmer penetrates the program by introducing a script featuring a code snippet that closely mirrors Meta Pixel, a renowned service for monitoring visitor activity, and incorporates several supplementary lines of code. This technique enables skimmers to avoid detection by conducting static analysis by external scanners and researchers. The extra lines of seemingly innocuous code make it easier to submit a PNG image with a Base64 encoded message attached at the end. This string is later retrieved, decoded, and converted into a JavaScript code snippet, which is executed by the loader code snippet. Facebook Based on this approach, a new method has been developed that involves opening the icon page via an absolute path, which provides a direct link to a "Not Found" page. This page then accesses a compromised section of code, which is then commented out with a special key, hiding the malicious code inside. This can happen when a site uses a third-party payment service that implements a payment form in an external iframe or on an external page. To bypass such scenarios, an attacker creates a fake form very similar to the original payment form and overlays it. When the user enters data into the fake form, an error appears, the fake form is hidden, the original payment form is opened, and the user is prompted to re-enter payment data. In this way, the old method of fraud and the new one are combined. How do you protect yourself? Buyers should pay attention to the address bar of the resource where the payment is made and uncharacteristic errors in the input form. Since thieves can utilize an active card with an empty balance for other fraudulent schemes, like money laundering, you immediately reissue the card and move all available funds to a savings or savings account as soon as you think you have been the victim of fraud. The cybercrime unit should pay attention to the new scheme and test systems for penetration.
