How a female Ukrainian hacker exposed a botched SEC case against day traders
A Ukrainian hacker who was held at gunpoint by a gang of cocaine-sniffing cybercriminals helped the Securities and Exchange Commission blow the lid of of a high-profile breach case that had wrongly accused American day traders, according to a report. Olga Kuprina, known by her online persona 'Ghost in the Shell,' became a whistleblower for the federal agency in the shocking cyberattack that infiltrated the SEC's Edgar filing system in 2016, Bloomberg News reported on Monday. Surrounded by cocaine, laptops and armed men, Kuprina was trapped by a local crime boss, Artem Radchenko, in her Kyiv apartment and ordered to hack perhaps the world's biggest repository of corporate filings, according to the outlet. Advertisement Radchenko allegedly hoped to sell unpublished filings for $200,000 apiece. 4 Kuprina was known by her online persona 'Ghost in the Shell.' Instagram/sky31337 But as the doped-up Radchenko barked commands at Kuprina, she plotted her escape — desperate to return to her 7-year-old daughter and expose the cybercrime, according to Bloomberg News. Advertisement When she demanded payment for the hack, Radchenko allegedly broke her nose and refused to allow her to leave, according to Bloomberg News. Kuprina, 34, later fled, contacted US authorities, and turned over hard drives and handwritten notes proving how she had accessed the SEC data. 'There were so many vulnerabilities there you cannot f–king imagine,' she told investigators. Edgar, she said, was an outdated, patched-together system that hadn't been properly secured in years. Kuprina, who had also hacked Citigroup, Nasdaq, Dow Jones and NASA, signed a plea deal with the feds and fled to the US in 2018, leaving her mother and daughter behind. Advertisement 4 Olga Kuprina is a Ukrainian hacker who turned whistleblower. Instagram/sky31337 In 2019, the SEC wrongfully scapegoated American day traders who were accused of pocketing $4.1 million from insider trades linked to the massive cyberattack that breached the Edgar filing system. It turns out those Americans may have simply been guilty of making smart, lucky bets. 'Today's action shows the SEC's commitment and ability to unravel these schemes and identify the perpetrators even when they operate from outside our borders,' the agency's head of enforcement said in a press release. Advertisement Sungjin Cho, a Los Angeles-based day trader, was startled to find federal agents banging on his door before dawn. They confiscated his devices, grilled him about foreign hackers, and accused him of profiting off stolen data. 'I don't know what we were expecting to find, but he didn't seem like a high-rolling criminal at all,' one FBI agent told Bloomberg News. Kuprina's cooperation with US authorities would reveal a months-long breach of the SEC's core system — and upend the agency's narrative. What the SEC didn't say in its official version of events was that the breach of Edgar had lasted far longer than publicly acknowledged — and had been exposed not by agency sleuthing but by Kuprina. Despite her central role in exposing the breach — and continuing to download documents as late as March 2017 — Kuprina wasn't mentioned in the SEC's complaint. 4 In 2019, the SEC brought charges against US traders over a hack that was perpetrated by Ukrainian cybercriminals, according to a report. Christopher Sadowski Instead, the commission zeroed in on Cho and his associates: David Kwon, a friend who traded through Cho's accounts, and Ivan Olefir, a Ukrainian client connected to Cho's trading firm. While the three made trades that aligned with earnings announcements, investigators found no direct evidence they had been in contact with the hackers, nor that they ever knowingly received stolen documents. Advertisement Still, the SEC charged them, citing high win rates on earnings trades and circumstantial connections. The Department of Justice, which was conducting a parallel criminal probe, ultimately declined to prosecute the traders — a move that signaled doubts about the strength of the case, Bloomberg News reported. Cho maintained that he and his colleagues were simply tracking unusual trading activity — looking for signs that others had inside information, then piggybacking on their bets. 'Any earnings or any market-moving announcement…there will always be some leak,' Cho told investigators. Advertisement 4 Gorodenkoff – 'And if you could detect that movement, that's the strategy.' Critics say the SEC needed a win — and chose easy targets. The agency faced pressure to respond after being hacked itself, and rather than focus on the Ukrainian masterminds still at large, it trained its firepower on traders who were within reach. In the end, Cho settled for $175,000 — a fraction of what the SEC claimed he made. He did not admit wrongdoing, but under SEC rules, he is not allowed to publicly say he's innocent either. Advertisement 'I'm not allowed to say I'm innocent, but I'll give you all the facts and people can decide for themselves,' he later said. In 2020, Kuprina pleaded guilty to federal charges related to Edgar and five other hacks, according to Bloomberg. She served a short jail stint before being released as she cooperated with investigators. A judge sentenced her to time served in 2023 in recognition of her cooperation, according to Bloomberg. Advertisement The skilled hacker now works for cybersecurity company Recorded Future Inc. — and was reunited with her mother and daughter, who were flown out of war-torn Ukraine by the US government. Meanwhile, hackers like Radchenko are still at large. And the SEC's Edgar system, though updated in parts, remains vulnerable according to cybersecurity experts. The Post has sought comment from the SEC, Kuprina, Cho and Kwon.

Irish Boxer Turned Pop Culture Star Ends 16 Year Hiatus, Returns Oct. 12 Against WBC's 18th-Ranked, Promoter Confirms
DUBLIN, IE / ACCESS Newswire / June 4, 2025 / Undefeated Irish boxer turned US Billboard Charting and multi-platinum artist Marc Mysterio (3-0, 2 KOs as pro) - his 2006-2009 BoxRec profile application pending - and 10-0-1 amateur standout under the late Gregory Leschishin of USA Boxing - tragically killed last month by a carjacker, according to Yahoo - resumes his world title quest with a clean bill of health after a 15+ year hiatus from the sport. Following a preliminary mutual understanding, Marc Mysterio is set to face the WBC's 18th-ranked Serhiy Radchenko (11-8-0, 5 KOs) on Oct. 12, 2025, in "Irish Pride vs. Ukrainian Glory: Marc Mysterio v. Radchenko," promoter Ville Ruutu of World Class Promotions (WCP) confirmed Wednesday. "WBC Ukraine President Mykola Kovalchuk played a key role in facilitating this mutual understanding, as shown by his initial WhatsApp response, 'I think Radchenko should take the fight,' and we remain grateful for his support." A 2009 basketball injury paused Mysterio's boxing, sparking a music career with hits alongside David Guetta, Avicii, Samantha Fox, Crash Test Dummies and Flo Rida, including "The Dancefloor" which entered the U.S. Billboard charts, plus TMZ, Radar Online, and Perez Hilton buzz, Miami Herald and Boston Globe coverage, and "Trailer Park Boys" fame culminating in 81,000,000+ streams from 15,000,000 listeners during September 2023-September 2024, resulting in over 1,250,000+ Fans and 15,000+ Super Fans on Amazon Music. Last year, he challenged Jake Paul to replace semi-retired opponent Ryan Bourland with himself in a February bout in Puerto Rico - backed by the IBA's former chairman who volunteered to sanction the proposed bout for their vacant super cruiserweight intercontinental championship - covered by the UK's Daily Express and The Irish Star, with Mysterio even posting read-receipts of his team's emails to Nakisa Biderian of MVP Promotions on his X account, @marc_mysterio. "I'm back to finish what I started," Mysterio declared. "On Oct. 12, every Irish fan must join this pilgrimage - Ukrainians will rally for Radchenko. It's Irish pride versus Ukrainian glory!" 2010 WBC Trainer of the Year Gabriel Sarmiento has recently been working with Mysterio in the months prior to Coach Greg's death, and will travel to Ireland for Marc's pre-fight camp. "Marc's skill reflects decades of work and has adapted well to my coaching," Sarmiento said. "He'll prove that he is both a machine and a legitimate contender - I believe Marc will dominate Radchenko." Radchenko, a former WBC silver Bridgerweight champion, has faced undisputed light heavyweight champion Dmitry Bivol and WBC Bridgerweight champion Kevin Lerena in May 2025. "I fight for Ukraine's glory - Slava Ukraini!" Radchenko has stated previously, translated from Ukrainian, reflecting his enduring inspiration. Jill Diamond, WBC secretary and WBC Cares global chairwoman, was quoted by the UK's Daily Express last year, "Marc Mysterio is a force in music and boxing and, moreover, a friend of the WBC and WBC Cares. We support his efforts." "At present, I look forward to donating a portion of my purse to WBC Cares, as well as tickets to the event for local disabled children," Mysterio notes, confirming his support of the charitable organization and youth. "Speaking personally, not for the DFA or Irish government, Marc inspires Ireland by blending boxing, music, and philanthropy, overcoming countless obstacles after his injury and the recent loss of his lifelong coach - embodying the essence of Irish pride in my view," said David Costello, an Irish diplomat and former head of mission to several countries. "On May 26, at the request of WBC Ukraine President Mykola Kovalchuk, we sent a letter to WBC President Mauricio Sulaiman seeking sanctioning for the Mysterio-Radchenko bout as a ranked fight under WBC rules, including proof of a venue hold for Oct. 12 at one of Europe's top 10 indoor arenas by 2024 ticket sales, as required for sanctioning," Ville Ruutu said. "With Irish and Ukrainian fans competing for scarce tickets, broadcasters like Netflix, ESPN, ESPN+, DAZN and Sky Sports are vying for exclusive rights - possibly drawn by Marc's ESPN 'First Take' tie, when Stephen A. Smith chose 'Be The Truth' for the show in 2016, and Netflix 'Trailer Park Boys' connection. This will influence our decision, though not decisively. We'll prioritize the networks' coverage of this landmark bout from now to early July over financial incentives, aiming for the best long-term outcome for both fighters and the Bridgerweight division. Broadcast partners will be revealed at the mid-July press conference." The official venue, pre-sale ticket date, broadcast partners and event sponsors unveil will occur at a mid-July press conference at which WCP anticipates, in light of both boxers statements, the live appearances of both warriors - as well as the official contract signing to formalize the bout - at a location, date and time to be announced in an early July press release. "I'll fight Radchenko on Oct. 12, with or without WBC sanctioning as a ranked fight. Defeating the 18th-ranked boxer - who entered May 2025 as silver champion - basically guarantees me a top-25 WBC Bridgerweight world ranking - sanctioning should be a mere formality of that result! This is a professional 10-round fight, three-minute rounds, no matter what! I am also volunteering to enter the WBC Clean Program aimed at eradicating PEDs from the sport, required for top 15 rankings in WBC. Finally, I aim to pioneer Bridgerweight, like Holyfield did for cruiserweight, a division ripe with talent, but lacking prestige to casual fans before his charismatic championship reign that paved the road for guys like Usyk, a friend of Radchenko - It all starts Oct. 12 - I just wish that Coach Greg was still here to witness it," Mysterio concludes.

‘Big fight' awaits Kevin Lerena after easy KO in WBC title defence
Matshelane Mamabolo | Published 5 hours ago KEVIN Lerena is spending a restful weekend in Sun City as he anticipates his 33rd birthday on Monday, his standing as South African boxing's golden boy still intact. 'Two Guns' gave himself the perfect pre-birthday gift on Thursday night by making a successful maiden defence of his WBC bridgerweight title, courtesy of a superb third-round TKO of Ukrainian challenger Serhiy Radchenko at the Sunbet Arena in Pretoria. And while a second defence is no doubt what's next in line, those thoughts will be far removed from his mind at least for the next week. His coach Pete Smith said immediately after the fight that there are plans for a 'huge fight' soon as they celebrated a victory that once again illustrated Lerena's boxing skills and punching power. 'During the period of being absent (Lerena had not fought for 14 months), I said to Kevin, 'You have to make a statement because the world is watching'. And they saw a true champion tonight.' A fight that had been anticipated to be evenly-fought, given Radchenko's standing as the silver champion of the division, quickly degenerated into a no-contest as the South African smashed the challenger to the canvas with a left hook in the second round. There was a second knockdown shortly thereafter as Lerena pummelled Radchenko, clearly looking for an early night. The bell saved the Ukrainian, but the champion fell on him like a ton of bricks at the start of the third, and his corner came to his rescue by throwing in the towel. Smith said while it would have been grand for his boxer to get a few rounds to help rid himself of the ring rustiness, they were not going to risk things. 'A fight is a fight. The danger is always at bay. We could not take a chance. We've been working on those precise movements that brought about this result. 'And now we are looking at having a big fight after this.' Such is Lerena's popularity that the Arena was packed by a vociferous crowd that chanted his name and sang 'Go Kevin Lerena' to drown out the ring announcer as he introduced the fighters. Typically, some part of the crowd booed when Radchenko's name was called out, and the roof went off as though the South African had already won. You knew he was ready to rumble when he sang heartily to the national anthem, raising his hands up at the end of it as if in victory. And he got that victory alright, Lerena scoring a sensational stoppage in what was a historic first ever WBC world title defence by a South African on home soil. 'I told you, 14 months no fighting. They were taking food off my kids' table, but when I turn up, I'm going to beat anyone,' Lerena said. 'It's an absolute honour. The biggest champions – the late Dingaan Thobela, Sugarboy Malinga – are so good to be mentioned along with those legends,' he said afterwards in reference to South Africans who held WBC world titles. Turning only 33 on Monday, there can be no denying that Lerena has the time to achieve enough success in the ring to elevate himself to the status of South African boxing legend.

Kevin Lerena stops Serhiy Radchenko in explosive return to the ring
South African boxer Kevin Lerena made a triumphant return to the ring with a dominant third-round stoppage of Ukraine's Serhiy Radchenko at the BetSun Arena in Pretoria on Thursday night. After more than a year of inactivity, the Johannesburg-born Lerena wasted no time in asserting his dominance, thrilling the home crowd with a clinical and aggressive performance that improved his record to 31 wins and 3 losses, with 15 knockouts. From the opening bell, Lerena controlled the pace of the bout, using his jab to keep Radchenko at bay and setting up punishing power shots that repeatedly pierced through his opponent's high guard. Radchenko, now 11-8 (5 KOs), struggled to mount any meaningful offence in return. The second round proved decisive, as Lerena landed a series of heavy left hooks, the first of which drove Radchenko into the ropes and the second dropping him hard to the canvas. Though Radchenko bravely got to his feet and attempted to survive by clinching, another knockdown followed shortly thereafter. Despite two knockdowns and signs of visible distress, Radchenko's corner allowed him to continue into the third round. Kevin Lerena capitalised swiftly, landing a final combination that dropped Radchenko to his knees. This time, his corner threw in the towel, prompting the referee to wave off the contest. Speaking after the fight, Lerena expressed his readiness to climb back into the international spotlight and issued a direct challenge to Britain's Fabio Wardley. 'I want bridgerweights, heavyweights – let's go!' Lerena declared in the ring, drawing loud cheers from his supporters. Lerena, who famously dropped Daniel Dubois three times in the first round of their 2022 clash before being stopped himself, now looks poised for another big-name bout in the heavyweight or bridgerweight divisions.
