China News Service, Beijing, April 4 (Reporter Sun Zifa) The reporter learned from the China Aviation Engine Group (China Aviation Engineering Group) on the 4th that the AEP100, a megawatt-class hydrogen fuel aviation turboprop engine independently developed by the Hunan Power Machinery Research Institute affiliated to China Aviation Engineering Group, was equipped with a 7.5-ton unmanned transport aircraft and successfully made its first flight at Lusong Airport in Zhuzhou, Hunan Province that day. This is the world’s first test flight of a megawatt hydrogen fuel aviation turboprop engine.
According to reports, the engine of the unmanned transport aircraft worked normally and was in good condition during the entire flight. It lasted 16 minutes in the air, flew a distance of 36 kilometers, flew at a speed of 220 kilometers per hour, and flew at an altitude of 300 meters above the ground. It returned successfully after completing the scheduled flight subjects, and the first flight was a complete success.

Industry experts said that the success of this world's first flight has achieved a stage leap from technology to engineering for China's independent development of megawatt-class hydrogen-fueled aviation engines. It marks that China has opened up the entire technology chain from core components to complete machine integration in the field of hydrogen-fueled aviation engines. It has verified the engineering reliability of matching the hydrogen fuel power system and the flight platform, laid a key foundation for the subsequent industrial application of hydrogen energy aviation, and is an important milestone in China's green aviation power development from technological exploration to engineering practice.
Experts said that as the cost of green hydrogen preparation further decreases in the future, the economic advantages and energy security advantages of hydrogen aviation power will gradually be revealed. Hydrogen fuel aviation engine technology is expected to be the first to be applied in low-altitude economic fields such as unmanned air cargo and island logistics, and gradually expand to manned regional aircraft. This technology will drive the collaborative upgrading of upstream green hydrogen energy preparation, midstream storage, transportation and refueling infrastructure, downstream high-end equipment and new materials and other industrial clusters, and continue to promote the green, low-carbon and high-quality development of China's aviation industry.

A loan of more than 9 million yuan had real collateral and sufficient market value, but the borrower was unable to repay it. It seemed like a contract dispute, but in the end he was charged with loan fraud and money laundering. The Jing'an District Procuratorate used a "penetrating review" to uncover the layers of disguise of financial crimes.
In December 2024, the public security organ applied for arrest of Park Moumou, accusing him of forging materials, concealing the true mortgage status of the mortgage, and defrauding Loan Company A of more than 9 million yuan. Pu Moumou used the property in his name as a mortgage, deliberately concealed the fact that he had borrowed more than 22 million yuan from Bank A as a mortgage, and tampered with the materials to falsely claim that only 9.85 million yuan was left unpaid. Company A lends money accordingly. Later, Park was unable to repay the debt and the crime was committed.
After arriving at the case, Park confessed to forging materials, but argued that the market value of the property of 32 million yuan was enough to cover the loan. The inability to repay was due to the delay in sale due to market fluctuations, and there was no intention to defraud.
The prosecutor in charge concluded that the collateral provided by Park was genuine and effective, that the residual value of the property at the time of the loan could still cover most of the loan, and that he had not evaded or squandered the loan, and that he would pay interest until the principal was due as agreed. It was determined that there was insufficient evidence for "illegal possession purpose". The Jing'an District Procuratorate made a decision not to approve the arrest in accordance with the law and recommended that the investigation agency continue to supplement evidence.
In August 2025, the case was transferred for review and prosecution. The prosecutor found that Park Moumou still had an operating company and other assets under his name at the time of the incident, and had already refunded one million yuan in compensation and later repaid the arrears in full, which still did not constitute the crime of contract fraud.
But prosecutors didn't stop there. By penetrating the flow of funds, it was found that Park applied for operating loans of more than 4 million yuan from Shenzhen Bank B and other institutions in the name of business operations, and all of them were actually used for futures investment. Prosecutors believe that he concealed the true purpose of defrauding the loan, causing the bank to lose more than 3.3 million yuan, and should be held criminally responsible for the crime of defrauding the loan.
At the same time, "one case and two investigations" were strictly implemented. Prosecutors found that in order to evade supervision, Park transferred and mixed the above-mentioned loans through multiple companies and personal accounts at multiple levels, and then "laundered" them and transferred 3.6 million yuan into his personal futures account. This behavior constitutes "self-laundering" and should be punished together with the crime of fraudulently obtaining loans.
The procuratorate also actively promoted the recovery of stolen goods and recovery of losses. Park Moumou reached a repayment agreement with the bank to recover losses to the maximum extent.
Recently, the Jing'an District Procuratorate filed a public prosecution against Park Moumou for the crime of loan fraud and money laundering. The court adopted all charges in the first instance judgment: sentenced to two years in prison and fined 30,000 yuan for the crime of loan fraud; sentenced to one year in prison and fined 10,000 yuan for money laundering; and punished several crimes concurrently. It was decided to execute a fixed-term imprisonment of two years and six months, suspended for three years, and fined 40,000 yuan.
The Jing'an District Procuratorate stated that it will continue to improve the professional capabilities of financial prosecution, strictly control facts, evidence, and laws, and build a strong financial security defense line by performing duties with high quality and efficiency.
On the evening of April 2, the French contemporary comedy "Art" made its 2026 premiere at the Jasmine Theater. As a repertoire of the Shanghai Dramatic Art Center, "Art" uses a white oil painting as a guide to reveal the layers of cracks in a friendship that has lasted for more than ten years due to conflicting concepts. On April 3, Mark, played by Chen He, made his debut on stage. This was his return to the drama stage after many years.
On the opening night on April 2, the first cast of "Art" composed of Xu Shengnan (playing Mark), Xie Shuai (playing Serge), and Han Xiuyi (playing Ivan) returned as last year's lineup. Xu Shengnan accurately captured Mark's fragile heart under his sharp appearance, Xie Shuai captured Serge's confidence and sensitivity just right, and Han Xiuyi used tense body language and speech speed to present Ivan's anxiety and embarrassment in the cracks of friendship.
On the evening of April 3, Chen He (played as Mark), Xie Shuai (played as Serge), and Zhang Ruihan (played as Ivan) took over the baton. Chen He, who made his first appearance in the play, portrayed Mark's strength and uneasiness in a real and tangible way. Xie Shuai once again showed Serge's complex emotional levels in the collision of different opponents. Zhang Ruihan, who also made his first appearance in the play, interpreted Ivan's dilemma through precise rhythm control.
French playwright Yasmina Reza has twice won the Tony Award and the Laurence Olivier Award. Her famous work "Art" premiered at the Comedy des Champs-Elysées in Paris in 1994. In 1996, Sean Connery, the first 007 actor, introduced it and made it into an English version that was performed at the Wyndham Theater in London. It has since been translated into more than 40 languages.
In 2001, Shanghai Dramatic Art Center put "Art" on the domestic stage for the first time, directed by Gu Yian and starring Xu Zheng, Lin Dongfu and Hao Ping. This version of it performed at the Jasmine Theater was directed by British director Paul Garlington and created by revival director Li Li.
"Art" revolves around a white oil painting worth 2 million yuan. Dermatologist Serge praised it highly, while aviation designer Mark scorned it, thinking it was just a "blank slate". Ivan, who was caught in the middle, tried to reconcile, but got himself into deeper trouble. A debate about the value of art eventually evolved into a torture of more than ten years of friendship and personal values.
In the ending of "Goddess of Justice", good will be rewarded with good and evil will be repaid with evil. It's not that the time has not yet come for not repaying. Gao Chengbin surrendered to the law, but Gao Shuhua finally found his way back.
I had expected that Gao Chengbin (played by Liu Zhuoxin) would be brought to justice, because doing so is in line with positive values, otherwise the audience will be angry.
But he didn't expect that he would continue to kill people later, and he didn't expect that his mother Gao Shuhua (played by Chen Wei) would help him, which almost allowed him to get away with it again.
They had expected that the upright Qiu Guangzheng (played by Tam Yaowen) would be punished collectively by the Department of Justice, but they did not expect that the disaster would affect Qiu Tianxue.
Therefore, girls must not only love themselves, but also maintain 200% vigilance, because girls are more likely to be deceived and more likely to suffer in a fight.
A girl dares to go to a nightclub to perform alone, and dares to enter a strange closed room to rest alone. Anyone with a little vigilance will not be deceived.
As a result, Yan Huizhi (Charmaine Sheh) almost missed the chance to become a judge. If Gao Shuhua found out without conscience, Gao Chengbin would be acquitted.
After all, the game account he communicated with Zhang Jingxiang (played by Feng Haoyang) was completely canceled as long as he destroyed the memory card of the smart camera glasses.
It is equivalent to death without evidence. Gao Shuhua, who only cares about immediate interests, is really determined to help conceal the truth, but Yan Huizhi and others have no choice.
Hu Yuze (played by Huang Ziyao), Su Lizi (played by Wen Songxian), Lidya (played by Ni Jiawen), Zhang Jingxiang (damn), they will die in peace.
I thought the "Wei Rongjin Wife Murder Case" was just a mention. After all, the case had been closed for so long, and the murderer was not unjustly accused, so there was still linkage.
It's also good that the judges and lawyers who bullied Yan Huizhi should be warned not to be so arrogant in the future. After all, justice will come late.
This Gao Chengbin was cruel enough and was not sentenced to death. After being imprisoned, he refused to visit Gao Shuhua and instead accepted visits from Yan Huizhi.
The Qiu Tianxue case and the Gao Chengbin case caused so much trouble for Yan Huizhi's family of three, but instead helped Zheng Shaowen (played by Zhou Jialuo) get promoted.
His relationship with Lin Yaqing (played by Dai Zuyi) is also on the horizon. Here I want to talk about Zhang Pinwei and Fang Guan (Li Chengchang), they are all debts!
Fang Guan, who prides himself on being noble, is willing to expose his own scars, even if he is late in life. Zhang Pinwei found someone to help his son escape the crime, but instead he was sent to a dead end.
Also, Officer Zhao (played by Yang Zhenghua) and Superintendent Chen (played by Lin Pulai) were in trouble with Huizhi at work, and as a result, old cases were overturned and backfired.
The drama between Yan Huizhi and Gao Shuhua in the courtroom is very exciting. Gao Shuhua always thinks of dirty tricks and always makes Yan Huizhi anxious and angry.
Yan Huizhi was always able to find new evidence, and could even convince the magistrate to serve as a witness, and even make Gao Shuhua switch sides at the last moment, so he had to accept it!
The most powerful thing about Hong Kong dramas is that they can always write plots that exceed the audience's expectations and dig a lot of pitfalls, but they can all come true in the end.
It can also make the bloody story mysterious and vivid, and it can vividly interpret the darkness of human nature, but the ending is sometimes good or bad.
The scenes between Charmaine Sheh and Chen Wei are really good to watch. Charmaine Sheh has a sense of majesty and is very suitable for playing the role of a female boss. I love watching her train her subordinates.
Chen Wei is very suitable for playing the role of a legal beauty. She doesn't seem to be playing a lawyer, as if she is a real lawyer, with that kind of aggressive and well-known attitude.
In summary, it is a very enjoyable Hong Kong drama that becomes more and more exciting as you go to the end. It is suitable for all ages, there is no violent plot, and it has both legal rules and warmth.
The FBI later confirmed that Patel's email had indeed been hacked, but "no sensitive information was leaked."
In the content released by the hackers, every photo of Patel was marked with a red logo - a cartoon man holding a submachine gun, next to the English name "Handala" in capital letters.
Handala was once considered a Palestinian hacker group, but an investigation by an Israeli cybersecurity company found that it was one of the multiple network "vests" used by the Iranian government's cyber intelligence department, and the real "operator" behind it was Yahya Hosseini Panjaki, a senior official in the Iranian intelligence system.
Soon, Handala claimed to have breached Patel's personal email and warned: "This is just the beginning for us."
Hackers That Even the FBI Can’t Prevent
After successfully hacking into Patel's mailbox, the Handala organization issued a post mockingly: "Current FBI Director Kash Patel once proudly hung his name on the headquarters building, but now his name appears on the hacked list. The FBI's so-called 'impregnable' system was easily defeated by our team within a few hours."
The U.S. Department of Justice subsequently intervened, linking the Handala organization to the Iranian Ministry of National Security, and offered a $10 million reward for relevant clues.

In fact, since the war between the United States and Israel started on February 28 this year, the activities organized by Handala have become more frequent. They have published a list of about 190 people related to the Israel Defense Forces and the government, and also listed employee information of the American aerospace company Lockheed Martin's headquarters in the Middle East.
The largest recent attack launched by Handala occurred on March 11. The target of the attack was American medical equipment manufacturer Stryker, a Fortune 500 medical technology company.

At 3:30 a.m. that day, Stryker employees around the world found that their computers and mobile phones were paralyzed, all data had been wiped out, and only the Handala Organization's logo remained on the screen. "My wife also works at Stryker," one employee said. "The login pages of all three of her computers were painted with hacker logos. It's a shame." Another employee described the situation on site as "terrible" and that many people's mobile phone data had been wiped out. "I can't even open emails now, and my work and life are completely messed up."
The Handala group subsequently claimed that they had stolen 51TB of Stryker data and wiped data from 200,000 devices. The U.S. Department of Justice quickly confirmed the figure.
The attack had a huge impact on Stryker. In a filing with the U.S. Securities and Exchange Commission, Stryker admitted that the hacker attack caused "a total disruption to order processing, production and shipments" and halted global operations. The Wall Street Journal reported that Stryker’s stock price fell 5.3% after the attack.
Surprisingly, the technical means used by Handala are not complicated. A network security expert revealed to NBC that Handala used Microsoft's Intune management software to carry out the intrusion. Intune is a cloud software originally used to allow company IT departments to remotely manage mobile phones and computers. Hackers stole the administrator account and deleted data on all devices in batches.
After the attack on Stryker, the Handala organization claimed that it was to avenge the Minab Elementary School in Iran that was attacked in a US-Israeli air strike. On February 28, a girls' elementary school in the city of Minab in southern Iran was attacked in a US-Israeli air strike, killing about 170 people, most of whom were children.

Handala wrote on his Telegram (encrypted social platform) channel: "For the children of Minab!"
"Whack-A-Mole"
Handala is a cartoon image created by Palestinian cartoonist Naji Ali in 1969: a boy who always turns his back to the world, symbolizing exile and resistance. More than fifty years later, a group of hackers chose to use "Handala" as their code name.
·The logo of the Handala organization. (US Cyber Express website)
In October 2023, a conflict broke out between Israel and the Palestinian resistance organization "Hamas" in the Gaza Strip. That month, a hacker group calling itself "Handala" made its first public appearance. At the time, it was seen as a pro-Palestinian hacker group.
However, with the recent escalation of the war between the United States, Israel and Iraq, Handala has repeatedly launched cyber attacks against American and Israeli targets. This caught the attention of Israeli cybersecurity company Check Point. They discovered that behind Handala was the Iranian hacker force "Void Griffin", which was affiliated with Iran's Ministry of Intelligence and National Security. This organization also has many aliases such as "Red Sandstorm", "Exiled Kitten" and "Homeland Justice".
The FBI later pointed out that the actual leader of Handala was Yahya Hosseini Panjaki, a senior official in the Iranian intelligence service.
Public information shows that Panjaki was born in Karaj, near Tehran, in 1975. He holds a doctorate in political science from the Islamic Free University in Tabriz and has published two papers in academic journals. He once single-handedly created the "Martyr Soleimani Force" and cooperated with Iran's Islamic Revolutionary Guard Corps to carry out missions around the world. As a result, he became a core and powerful figure in Iran's intelligence system.
In September 2024, the U.S. Department of the Treasury announced sanctions on 12 Iranian individuals, and Panjaki was among them. In May 2025, the FBI issued a wanted order, accusing Panjaki of using intelligence networks and cyber operations capabilities to plan terrorist activities around the world. However, according to the American non-profit media Lawfare, Panjaki was killed in a recent US-Israeli air strike on Iran.
·In May 2025, the FBI issued a wanted warrant for Panjaki. ("FBI Most Wanted" official X account)
But Panjaki's death did not stop Handala. Instead, it set off a climax of action for the organization.
Check Point discovered that Handala recently launched a bounty system called "Handala Red Notice" that uses cryptocurrency to pay bounties. Rewards for "level one high-value intelligence targets" such as Israeli Mossad and Military Intelligence Bureau officials can be as high as $50,000.
Handala's move was not a random retaliation, but a "benchmark" response to the US-Israeli assassination list.
Not long ago, Israeli Defense Minister Katz publicly announced that the Israeli military could strike "any senior Iranian official" without approval. At the same time, the U.S. State Department, through the "Rewards for Justice" program, publicly solicited information on 15 senior Iranian military and political officials, offering a reward of up to US$10 million. The list includes Iran's new Supreme Leader Mujtaba Khamenei, as well as the assassinated Supreme National Security Council Secretary Larijani, Intelligence Minister Khatib and others.
Currently, the FBI has seized two of Handala’s domain names, but Handala quickly relaunched its website under a new domain name. Check Point executive Gil Messing believes that this may just be a long-term game of "whack-a-mole". "In the past, they have always been able to bypass the ban and make a comeback by opening new domain names."

"Asymmetric Warfare"
The United States and Israel have launched joint military operations so far, which have caused huge losses to Iran. According to statistics from the United Nations International Organization for Migration, so far, 82,000 civilian buildings have been damaged in Iran and 180,000 homes have been destroyed.
Faced with such losses, Iran chose to fight back in another way. When military equipment does not dominate, they turn cyberspace into a lever for leveraging strategic balance.
In February this year, the Tasnim News Agency, a subsidiary of Iran's Islamic Revolutionary Guard Corps, published a long article detailing its combat plan against the United States, with a focus on cyber warfare. The article said that Iran will eventually make the United States pay an unbearable price through an "asymmetric protracted war."
"Iran's 'asymmetric war' is an effective way to avoid direct confrontation with the United States and Israel and instead use its own advantages to use low-cost attacks to deter its opponents." Qian Feng, a researcher at the National Institute of Strategic Studies at Tsinghua University, told Global Reporter: "Although Handala's hacking of Patel's email did not steal military secrets, it could have the effect of humiliating the U.S. law enforcement and intelligence systems, thereby undermining the credibility of the Trump administration. The paralysis of the medical system may trigger domestic public opinion in the United States and amplify public anxiety about war."
But Iran's cyberwarfare goes beyond hacking. According to Tasnim News Agency, the plan also includes direct attacks on U.S. data centers in the Gulf region.
In early March 2026, Iran's Islamic Revolutionary Guard Corps used low-cost "Kamikaze" suicide drones to launch direct attacks on two data centers of Amazon Cloud Services in the United Arab Emirates, and also attacked a facility in Bahrain. Russia's TASS News Agency stated that this is the first attack specifically targeting commercial cloud computing infrastructure in modern warfare.
The attack caused the local banking system to collapse, the trading platform to paralyze, and the payment system to go down - financial institutions such as Emirates National Bank and First Bank of Abu Dhabi reported severe service disruptions. Industry experts estimate that data center failures cost approximately $6,000 per minute.
Cynthia Kaiser, a former senior FBI cyber officer, commented: "This is not just revenge, but Iran is telling the world that they can bring the war to the United States." Qian Feng believes: "Although the United States has a clear advantage on the conventional military battlefield, on this invisible front, it will fall into a long-term war of attrition that will become increasingly troublesome."
However, this has also raised concerns. Russia's TASS news agency commented: "For the international community, this incident is a warning that the globalized digital economy has exposed new weak links."
