SINGAPORE - A Chinese n ational, who allegedly created malware that compromised millions of residential computers around the world, was denied access to flash drives said to contain hidden files and 'home manuals' storing cryptocurrency passwords. Wang Yunhe, 36, who was arrested in Singapore on May 24, 2024 and is facing extradition to the United States, had applied for access to or to make copies of his four flash drives currently in police custody . Following a request from the US authorities, the Singapore Police Force's (SPF) Commercial Affairs Department had seized a total of 50 items from Wang including bank cards, mobile phones, a laptop, a CPU, and electronic storage devices, including four flash drives. In a judgment dated June 30, District Judge Cheng Yuxi said that the flash drives seemingly contained simple files. However, they contained encrypted hidden volumes with a total of 21 files – duplicated across the flash drives – though only a portion were accessible to investigators. The files contained screenshots and cryptocurrency wallets which US authorities suspect were linked to a cluster of deposit addresses holding approximately 2,000 bitcoins. According to the authorities, Wang had an ulterior motive to gain control of them. She added that there were also files that were deliberately labelled with innocuous -sounding file names – such as 'Movie2023.6.10th' – and content that appeared harmless like home manuals . The American authorities suspect that these files might contain passwords or seed phrases, which are sequences of random words that store the data required to access or recover cryptocurrency, which Wang planned to use to re-access his cryptocurrency wallets. There were also files that allowed the quick, secure and permanent deletion of data from storage devices, District Judge Cheng added. She said that considering one of the four counts for which Wang was wanted by the US authorities was money laundering including through the use of cryptocurrencies, she agreed with the Singapore state's submissions that it would be very difficult to ascertain what type of information Wang would have access to if he was allowed to review the drives. She also agreed that there was a risk that he would be able to corrupt evidence or initiate a cryptocurrency transaction to dissipate assets even before the committal proceedings for extradition, adding that the data could also be deleted. 'This problem was compounded by the fact that the applicant was the only one who knew how to access hidden volumes in the flash drives in the first place, as well as the significance (if any) of unassumingly named files,' 'As such, 'what (might) appear to be innocuous phrases in the files or documents (might) inadvertently reveal hints about a mnemonic phrase, seed phrase, or password' to access the cryptocurrency accounts,' the judge said, quoting from the affidavit from an SPF officer. She added that these were not risks that could be ameliorated by imposing conditions on access, such as allowing only Wang's lawyers to access the flash drives. Wang, who is represented in Singapore by Mr Suang Wijaya and Mr Ng Yuan Siang from Eugene Thuraisingam LLP, is facing extradition to the US to stand trial in the US District Court for the Western District of Washington for conspiracy to commit computer fraud, aiding and abetting computer fraud, conspiracy to commit wire fraud and conspiracy to commit money laundering. According to the US extradition request and supporting affidavit, these centred on the Wang's alleged development and distribution of malicious software that compromised residential computers and gained unauthorised access to their IP addresses that were subsequently sold through a residential proxy service known as the 911 S5. Cybercriminals had allegedly utilised this service to connect to the internet through IP addresses of the compromised computers, effectively concealing their true locations. The scheme is said to have generated over US$99 million (S$126 million), which was later laundered through various channels, including through cryptocurrency transactions. In dismissing Wang's application to access his flash drives, the judge also noted that there was evidence of Wang's history of conduct in protecting his cryptocurrency assets. For example, Wang's cousin had admitted in Thailand to US authorities that Wang had taken steps to protect his cryptocurrency assets previously, including giving instructions to his family members on how to access his assets, decrypt the files, and transfer cryptocurrency if he became unavailable. Wang had also deleted data from the 911 S5 database server, Skype and other chat logs , in an attempt to hide his actions when an article was published to expose the potential criminality of the service. The judge said that while there was a statutory declaration from Wang's cousin that was affirmed in China, disavowing the statements he had made in Thailand, it was only authenticated by a notary public and therefore could not be properly admitted as evidence. Wang had also made other applications to the court that were dismissed. These included for a ruling that his bank cards, electronic devices and flash drives were unlawfully seized as well as an order requiring the Singapore state to summon all the prosecution witnesses whom the US Department of Justice intends to rely upon in proceedings there, to the committal hearing here . According to the judgment, Wang continues to be remanded pending the committal hearing to determine whether he should be extradited.

Huawei's leadership shuffle at research arm Noah's Ark Lab signals heated AI competition
Huawei Technologies has named a new head at its artificial intelligence (AI) research arm, according to a Chinese media report, as domestic competition among Big Tech firms and start-ups in this field intensifies. Advertisement Shenzhen -based Huawei promoted Noah's Ark Lab senior researcher Wang Yunhe as leader of the AI research unit, replacing previous head Yao Jun, according to a report on Monday by Chinese tech media Leiphone, citing people familiar with the matter. The leadership change might lead to further personnel adjustments at the unit, the report said. Huawei did not immediately respond to a request for comment on Tuesday. The move reflects how US-sanctioned Huawei is bolstering its AI capabilities with a young engineer like Wang – who works on areas such as deep learning, model compression and computer vision at Noah's Ark Lab – amid a heightened search for talent in the nascent domestic AI sector.
