This report examines current cases, explains the background, and provides concrete protective advice for readers. July 2026 Investigative Report
Cum-Ex & Cum-Cum: The billion-dollar fraud at everyone's expense
BaFin has confirmed: German banks, insurance companies and other financial institutions are contributing around Costs of 7 billion euros as a result of their involvement in Cum-Ex and Cum-Cum tax fraud schemes. But what's behind it?
In these transactions, shares were traded back and forth around the dividend record date in such a way that capital gains tax was refunded multiple times by the state—even though it had only been paid once or not at all. This mechanism cost the German treasury billions over decades.
Investigations are in full swing nationwide. Tax investigators, public prosecutors, and international authorities are working together to bring those responsible to justice. In the end, taxpayers will foot the bill—through less money for schools, hospitals, and infrastructure.
What is Cum-Ex?
Shares were traded multiple times between buyers and sellers shortly before the dividend record date. Several parties simultaneously applied for a refund of the capital gains tax—even though the government had only received it once.
What is Cum-Cum?
Foreign investors lent their shares to German institutions before the cut-off date in order to collect a tax refund to which they were not actually entitled.

Searches at Deutsche Bank: Postbank heir under suspicion
At the end of July 2026, tax investigators again searched the headquarters of Deutsche Bank in Frankfurt — this time in connection with suspicious Cum-cum transactions of Postbank from the years 2008 to 2010. The estimated total damage to the treasury amounts to approximately 28 billion euros nationwide; this complex alone is supposed to cover 350 million euros be.
Legal succession as a risk
Deutsche Bank took over Postbank completely. With this acquisition, it inherited not only customers and branches, but also potential legal liability for transactions that had been conducted under the Postbank umbrella for years.
Why old deals are causing problems today
Tax investigators can sometimes trace transactions back up to ten years or more. Digital evidence, witness statements, and international legal assistance make it possible to completely reconstruct transactions from 2008–2010.
Investigation methods
Emails, internal memos, business records, and server contents are being seized. At the same time, prosecutors are questioning former employees and cooperating with European authorities.
AI, deepfakes and shock calls: The new wave of fraud
In July 2026, security authorities registered an alarming increase in organized fraud methods that specifically utilize artificial intelligence. Two cases exemplify a nationwide threat.
Karlsruhe: Shock call from fake official
An alleged "court employee" called an elderly couple and claimed that a family member was in custody. After paying "bail," the victims handed over cash, jewelry, and valuables to a "collector." The damage was considerable, and the perpetrators fled.
Saxony: Deepfake investment of over €1 million
A woman trusted AI-generated promotional videos in which well-known personalities supposedly recommended an investment platform. After several transfers, she lost over [amount missing]. 1 million euros. The videos were deceptively real — computer-generated, but hardly distinguishable from real faces.
Authorities will NEVER request bail payments or the handover of cash to strangers over the phone. Hang up immediately and call the police on 110.
Protective measures: How to detect fraud in time
Whether it's a shock call, a deepfake video, or fake government agencies—perpetrators always use the same psychological tools: time pressure, fear, and trust. Those who know the warning signs can protect themselves.
Warning sign: Time pressure
„"You must act NOW!" — No reputable government agency, bank, or court will pressure you over the phone. Hang up and take a deep breath.
Detecting Deepfakes
Look for unnatural mouth movements, blurred hair edges, and a lack of facial expression. Manually search for the video on the person's official website.
Check before every investment
Check financial products on the BaFin website (bafin.de). Reputable providers are registered and transparent about risks.
Get a second opinion
Speak to relatives, friends, or a consumer advice center before transferring or handing over any money.
Bayreuth: "Your daughter is dying" — 330,000 euros lost
An elderly couple from Bayreuth lost around 330,000 euros through one of the most gruesome scams: the so-called "shock call with a sick relative." Scammers claimed that the couple's daughter was seriously ill and urgently needed expensive medication from abroad.
Under enormous emotional pressure and fear for their child, the elderly couple acted quickly—and handed the money over to an unknown "collector." The case demonstrates how criminals systematically exploit psychological vulnerabilities.
Why older people are particularly at risk
- Greater wealth through savings and property
- Stronger emotional bond with family
- Less experience with modern scams
- More often alone at home and unreachable
- Rare instant digital cross-check
What needs to be done immediately
- Hang up and call the family member back directly.
- Never hand over money or jewelry to strangers.
- Involve a neighbor or trusted person
- In case of suspicion: Call the police at 110.
- Always report incidents, even afterwards.

Disappear
The pattern is always similar: Victims are lured in by eye-catching advertising promising unrealistically high returns. A professional-looking platform displays supposed profits—until the money is gone forever.

AI makes fraud more believable: €1 million lost through deepfake videos
In Central Saxony, one woman transferred a total of over 1 million euros to various accounts — lured by AI-generated videos in which well-known personalities supposedly promoted an investment platform. The videos appeared deceptively real.
This is not an isolated incident. Deepfake technology is now so sophisticated that even technically savvy people cannot immediately recognize the forgery. Combined with social media advertising algorithms that specifically target people interested in investments, this creates a dangerous mix.
→Step 1: Algorithmic targeting
Scammers place advertisements on platforms like Facebook, YouTube, or Instagram — specifically targeting users who are looking for investments.
→Step 2: Celebrity deepfakes generate trust
AI tools generate compelling videos featuring the faces of well-known politicians, presenters, or entrepreneurs — without their knowledge or consent.
→Step 3: Professional fake platform
Victims are directed to deceptively realistic investment platforms. Initially, even small profits are paid out to build trust.
→Step 4: Money disappeared
Once larger sums have been deposited, withdrawals are blocked and the platform disappears. The money is usually irretrievable.
„Operation Chargeback“: Neobanks targeted by global fraud networks
The Financial Intelligence Unit (FIU) recalls one of the largest credit card fraud operations in German history: „Operation Chargeback“. Millions of fraudulent online subscriptions were billed – the damage amounts to approximately 300 million euros, are affected 4.3 million people in 193 countries.
Why neobanks?
Digital banks like N26, Revolut, or Wise allow for quick account opening with fewer verification procedures. For fraudsters, this means easier money laundering, more difficult-to-trace transactions, and international reach.
Global networking
„Operation Chargeback“ was not a local phenomenon: The perpetrator networks operated from several countries simultaneously, using shell accounts and cryptocurrencies to conceal the money flows.
Consequences for consumers
Millions of account holders discovered unknown small withdrawals. Many only noticed the fraud months later — chargebacks were systematically delayed or blocked.
Signa / Benko: When real estate empires fall
The Berlin public prosecutor's office has filed charges against four former managers of the Signa Group for illegal money transfers and embezzlement amounting to millions of euros. At the same time, the Austrian Supreme Court (OGH) upheld the convictions of... René Benko due to insolvency fraud.
The Signa Group was considered one of Europe's largest real estate and retail empires—with department stores, luxury hotels, and office towers. Its collapse reveals how political entanglements, opaque structures, and aggressive debt financing can bring down a seemingly unshakable structure.
Lessons from the Signa case
- Complex holding structures make tracking difficult.
- Political affiliation does not protect against criminal liability.
- Insolvency law as the last safety net for creditors
Wetterau district & Thuringia: Fraud „on your doorstep“
Not all fraud cases occur in major cities or financial corporations. Two recent cases show that criminals are active everywhere — and that ordinary people can become victims.
Wetterau district: Arrest of an investment fraudster
Police in the Wetterau district arrested a 38-year-old suspect who allegedly defrauded investors with fictitious or massively overvalued investments. The case serves as a reminder: such perpetrators are not anonymous—they often live in the neighborhood. And for every convicted fraudster, there are dozens of cases that never make the headlines.
Thuringia: The fake bank employee
In the Hildburghausen district, a woman claiming to be a "bank employee" called a man and asked him to confirm his account details for "security reasons." The result: approximately 35,000 euros were debited. Social engineering in its purest form — no technical knowledge required, just a convincing voice and the right script.
Real banks ask never If you receive a call asking for your PIN, TAN, or password, hang up immediately and call the official bank hotline yourself.
Conclusion: Vigilance is the best protection.
July 2026 has shown that financial crime is not an abstract problem for large corporations and authorities. It affects elderly couples in Bavaria, savers in Saxony, bank customers in Thuringia—and potentially every one of us. The perpetrators' methods are becoming increasingly sophisticated; AI is making forgeries almost perfect. This makes it all the more important to remain informed, critical, and vigilant.
Always check first, then act.
Whether it's an investment offer, a call from a government agency, or a message from your bank—take your time. Reputable organizations never pressure you to act immediately.
Independently verify sources
Call banks and government agencies back using official numbers. Never click on links in suspicious messages or advertisements.
