There is a special kind of absurdity in watching modern technology resurrect old ghosts. In the latest episode of European disinformation, unknown hackers attempted to do just that by planting two fake news articles in the Polish media about the so-called “territorial debts” of the Czech Republic. The story was designed to look as though it had jumped out of an official diplomatic cable, complete with a fake website modeled on Czech Radio and a set of fabricated Facebook accounts where imaginary diplomats commented authoritatively on the demarcation of the Polish-Czech border. According to the Polish cybersecurity portal CyberDefence24.pl, the entire operation was far too sophisticated to be dismissed as the work of a lone prankster. The aim, investigators believe, was to poison the relationship between two neighbors that have largely put their historic differences behind them. The report, carried by UNN with reference to Radio Prague, describes a coordinated disinformation campaign that used artificial intelligence, cloned media brands, and social media manipulation to create the impression that Poland was preparing to demand Czech territory. The details were not just false; they were deliberately engineered to play on national anxieties and historical wounds, and the way they were exposed says as much about the vulnerabilities of the digital age as it does about the resilience of Polish-Czech friendship.
The fabricated story revolved around an allegedly existing document from the Polish Ministry of Foreign Affairs that demanded a change to the Polish-Czech border and the transfer of approximately 638 hectares of Czech territory to Poland. That document, the article claimed, was proof that Warsaw had revived a long-dormant territorial claim. CyberDefence24.pl was quick to notice something strange: the fake document was written entirely in Czech except for the last few words, which were rendered in Polish. That linguistic fingerprint strongly suggested the text had been generated or translated with the help of artificial intelligence, and then stitched together carelessly by someone who did not fully understand the languages involved. But the hackers did not stop there. They also breached the security system of the Polish regional radio station Radio PiK and published a second article on its official website, claiming, “with reference to the Czech media,” that Warsaw intended to occupy six hundred hectares of Czech territory. The discrepancy between six hundred and six hundred thirty-eight hectares, and the shifting details from one fake piece to another, hinted at a campaign that prioritized speed and chaos over consistency. The story circulated in a fragmented media environment where headlines often travel faster than corrections. For a few hours, a casual reader might have been forgiven for thinking that a genuine diplomatic crisis was unfolding between Poland and the Czech Republic, when in reality neither government had made any such demand and the entire premise was a fabrication.
The reaction from political leaders in both countries was swift, and it revealed just how seriously the authorities took the attack. Polish Foreign Minister Radosław Sikorski addressed the story directly on social media, urging people not to fall for the manipulation. “Do not let them turn us against each other,” he wrote. To underline the point, he brought up a genuinely painful historical moment, saying that the annexation of Zaolzie before the Second World War was one of the stupidest decisions in the history of Polish foreign policy. He also reminded Czechs that Poland, represented by President Lech Kaczyński, had publicly apologized for that act at Westerplatte in 2009. It was a remarkably open and vulnerable way for a senior statesman to respond to a lie, and it underscored a broader truth: the best antidote to disinformation is not denial, but honest acknowledgment of the past. Prime Minister Donald Tusk took a lighter but equally effective approach. He posted a picture of Pat and Mat, the beloved Czech-Slovak animated duo known for their bumbling do-it-yourself adventures, and wrote that Poland and the Czech Republic are true friends. The image was a subtle and humorous rebuke to the anonymous provocateurs, suggesting that no fake document or hacked website could undo the cultural closeness that ordinary Poles and Czechs feel for one another. The Czech Ministry of Foreign Affairs, for its part, condemned the disinformation and calmly explained the real issue behind the story, refusing to let the loudest voices define the conversation.
What made the hoax so insidious was that it contained a kernel of historical truth. The fake articles were not created out of thin air; they were built on a long-standing dispute that has real roots in twentieth-century geopolitics. Under a treaty signed in 1958, the Czechoslovak-Polish border was formally demarcated, a process that shortened its overall length by eighty kilometers. During the complex calculations of territorial gains and losses, a discrepancy emerged in Poland’s favor of approximately 368 hectares. For decades, this tiny sliver of land has been referred to, in diplomatic shorthand, as a “territorial debt.” Since 1992, Prague and Warsaw have held a series of negotiations aimed at settling the matter, not because either side seriously expected a border war, but because unresolved administrative questions have a way of lingering in the background of bilateral relations. The issue is small in practical terms, but it is rich in symbolic potential, and that made it perfect material for a disinformation campaign. In February 2026, Czech Foreign Minister Petr Macinka discussed the issue with his Polish counterpart Sikorski and made the position of Prague absolutely clear. “There will be no question of any territorial or financial compensation,” he said. “On the contrary, we are saying that we will resolve this dispute through a joint project aimed at flood protection.” That simple, constructive sentence cut through the fog of fake news and demonstrated that real diplomacy is about cooperation, not conquest.
As the dust settled, attention turned to the question of who had orchestrated the whole affair. Intelligence services from both countries began investigating, and their preliminary findings pointed in an uncomfortable direction. “The perpetrators’ modus operandi corresponds to methods known to be used by the Russian side,” said Poland’s domain name registrar NASK, a state institution that deals with internet security. At the same time, NASK was careful to add that the organizer of the incident had not been unequivocally identified. In other words, the fingerprints looked familiar, but proof was still lacking. Slovak journalist Lukáš Valášek, who closely follows disinformation campaigns, noted that the operation stood out for its extremely broad set of tools and its high degree of coordination. The authors used artificial intelligence to generate text, built a convincing fake website that imitated Czech Radio, created social media profiles for diplomats who did not exist, and compromised the security systems of a real regional broadcaster. That is not the work of an enthusiastic amateur; it is the signature of a professional operation with resources and a clear strategic objective. Czech and Polish law enforcement agencies have been tasked with identifying the organizers and, presumably, with preventing similar attacks in the future. But the difficulty of tracing such campaigns is well known. The internet allows actors to hide behind proxies, encrypted communications, and stolen identities, and by the time investigators begin their work, the original trail has often gone cold.
Ultimately, the fake territorial debt affair is more than a curious footnote in the history of Polish-Czech relations. It is a reminder that disinformation does not need to be entirely plausible to be dangerous. It does not need to convince everyone, or even most people. It simply needs to create enough confusion and hurt to plant a seed of resentment in the minds of a few. The story of a Polish demand for Czech territory was absurd, but it touched on a sensitive subject, and had it not been exposed quickly by cybersecurity experts and challenged forcefully by political leaders, it might have lingered as a half-remembered suspicion in the margins of public consciousness. The response from Warsaw and Prague, however, showed a mature understanding of what is at stake. Instead of letting the lie dictate the agenda, both governments used the moment to speak honestly about history, to emphasize their shared future, and to reaffirm that their relationship is built on far more than maps and treaties. The unfinished question of 368 hectares may someday be settled through a joint project for flood protection, which would be a far better legacy than any territorial claim. In the meantime, the episode stands as a useful lesson for ordinary citizens: when a story seems designed to make us angry at our neighbors, it is worth pausing to ask who benefits, and why. The friendship between Poland and the Czech Republic did not begin with social media, and it will not be undone by it. But preserving that friendship in an age of algorithmic manipulation requires vigilance, good humor, and the courage to choose trust over fear.
