BIN Credit Card Attack?

BANK IDENTIFICATION NUMBER – DEFINED

What Is a BIN Attack?

The BIN, or the Bank Identification Number, is the first six digits on a credit card. These are always tied to its issuing institution – usually a bank. In a BIN attack, fraudsters use these six numbers to algorithmically try to generate all the other legitimate numbers, in the hopes of generating a usable card number.  

How Does a BIN Attack Work?

Fraudsters conduct BIN attacks by generating hundreds of thousands of possible credit card numbers and testing them out.

  1. A fraudster looks up the BIN of the bank they will target. Ranging from four to six digits, this information is in the public domain and is thus easy to source.
  2. Using dedicated software such as an auto-dialer, they generate thousands, often tens of thousands, combinations of possible existing card numbers by this issuer.
  3. At this point, these credentials need to be tested. The fraudster identifies a suitable online shop or donation page.
  4. They start card testing by attempting a small payment with each generated card number.
  5. They keep track of the small percentage of card details that worked, which they are ready to use in earnest for their fraudulent pursuits.

Remember that the fraudster will start off with only six digits, yet there are many more card details required for a successful transaction. If those are entered erroneously, the transaction will decline. This includes the CVV number, the expiration date, as well as likely address verification service (AVS) failures. Card testing transactions are executed remotely in a fast fashion, so distance checks should also be a hint as well as velocity alerts. 

Fraudsters may use bad merchant accounts directly for this purpose, or more frequently involve multiple online stores and services during a BIN attack, as their attempts keep getting blocked at most outlets.

MEDICAL PRACTICE: Valuation Adjustments

NET INCOME STATEMENT AND BALANCE SHEET ADJUSTMENTS

Net Income Statement Adjustments

When analyzing a set of financial statements to determine practice value, adjustments (normalizations) generally are needed to produce a clearer picture of likely future income and distributable cash flow. It also allows more of an “apples to apples” line item comparison. This normalization process usually consists of making three main adjustments to a medical practice’s net income (profit and loss) statement.

1. Non-Recurring Items: Estimates of future distributable cash flow should exclude non-recurring items. Proceeds from the settlement of litigation, one-time gains/losses from the selling of assets or equipment, and large write-offs that are not expected to reoccur, each represent potential nonrecurring items. The impact of nonrecurring events should be removed from the practice’s financial statements to produce a clearer picture of likely future income and cash flow.

2. Perquisites: The buyer of a medical practice may plan to spend more or less than the current doctor-owner for physician executive compensation, travel and entertainment expenses, and other perquisites of current management. When determining future distributable cash flow, income adjustments to the current level of expenditures should be made for these items.

3. Non-cash Expenses: Depreciation expense, amortization expense, and bad debt expense are all non-cash items which impact reported profitability. When determining distributable cash flow, you must analyze the link between non-cash expenses and expected cash expenditures.

The annual depreciation expense is a proxy for likely capital expenditures over time. When capital expenditures and depreciation are not similar over time, an adjustment to expected cash flow is necessary. Some practices reduce income through the use of bad debt expense rather than direct write-offs. Bad debt expense is a non-cash expense that represents an estimate of the dollar volume of write-offs that are likely to occur during a year. If bad debt expense is understated, practice profitability will be overstated.

Balance Sheet Adjustments

Adjustments also can be made to a practice’s balance sheet to remove non-operating assets and liabilities, and to restate asset and liability value at market rates (rather than cost rates). Assets and liabilities that are unrelated to the core practice being valued should be added to or subtracted from the value, depending on whether they are acquired by the buyer.

Examples include the asset value less outstanding debt of a vacant parcel of land, and marketable securities that are not needed to operate the practice. Other non-operating assets, such as the cash surrender value of officer life insurance, generally are liquidated by the seller and are not part of the business transaction.

POA: Power of Attorney Mistakes

Posted on March 17, 2025 by Dr. David Edward Marcinko MBA MEd CMP™

The Power of Attorney Mistake That Could Cost You Everything

By Rick Kahler CFP®

***

Recently, reading a training manual on elder abuse, I was reminded of a financial risk that is often overlooked. One of the fastest and easiest ways to unravel your financial security is to have the wrong person gain control of your money.

The example in the manual mirrored a heartbreaking situation I once experienced with a long-term client. As her mental and physical health declined, this single woman moved into assisted living. Her newly designated power of attorney, a relative from out of town, took control of her financial affairs.

Almost immediately, without consulting us, the relative began making large withdrawals, closed her accounts, and transferred funds elsewhere. They challenged the financial plan, investments, and strategies we had established to safeguard the client’s financial security and provide for her long-term care. Even though their actions threatened the client’s wellbeing, we were powerless to stop them. Our only recourse was to report the behavior to the authorities.

This heartbreaking and frustrating experience underscored just how critical it is to be mindful when executing a Power of Attorney. Besides designating someone you trust, it is wise to build in safeguards to prevent even a well-meaning relative from inadvertently derailing a carefully constructed financial plan.

One such safeguard is to include a financial advisor in your POA—as long as that person is a fee-only, fiduciary advisor with an obligation to act in your best interests. In many cases, advisors are hesitant to suggest this option because they are sensitive to the potential conflict of interest and do not want to appear self-serving. An unfortunate reality is that you should be cautious if an advisor, particularly one who sells products on commission, seems eager to be added to your POA.

Including your financial advisor in your POA does not mean you designate them as your agent to manage your affairs. Instead, you include a clause naming them as the professional of record you want your designated agent to continue working with. This creates continuity and accountability. It prevents your agent from replacing your advisor with someone who may be unfamiliar with your needs and goals, unqualified, or untrustworthy.

Your advisor might also recommend adding a secondary safeguard, such as naming an attorney or accountant to oversee the selection of a successor advisor in case your current advisor is unable to continue. This additional layer of protection ensures that the financial professionals guiding your portfolio remain aligned with your best interests. Taking these extra steps can save you—and your loved ones—from significant financial stress down the road.

Including safeguards in your POA is not about mistrusting your loved ones, but about equipping them with the right resources and support to act in your best interest. Financial management is complex, and it requires expertise that most people, even those with the best intentions, may not possess.

One of the hardest parts about planning for diminished financial capacity is the emotional aspect. No one likes to imagine a time when they might not be able to manage their own money. But in reality, taking steps now to protect your financial future is the ultimate act of control. It can help ensure that your wishes are respected and the financial foundation you’ve worked so hard to build remains intact.

Remember, too, that avoiding conversations often increases financial vulnerability. If you don’t have a POA or aren’t comfortable with what you do have, now is the time to bring it up with your advisor, attorney, or a trusted family member. These safeguards are about protecting yourself. They also support those you will rely on to care for you and your financial legacy,
