Spy in Silicon Valley: Chinese-American admits to stealing classified US military tech
According to the US Department of Justice (DOJ), 59-year-old Chenguang Gong, from San Jose, California, admitted guilt to one count of theft of trade secrets and remains free on a $1.75 million bond.
The DoJ says Gong's actions caused an intended economic loss of more than $3.5 million. He faces a maximum sentence of 10 years in prison, with sentencing set for 29 September.
DOJ prosecuters say Gong had transferred over 3,600 files from a Los Angeles-area research and development firm, where he was briefly employed last year, to personal storage devices.
The files included blueprints for advanced infrared sensors intended for use in space-based systems to detect nuclear missile launches, as well as to track ballistic and hypersonic missiles.
Other documents stolen by Gong pertained to sensors designed to equip US military aircraft with the ability to detect incoming heat-seeking missiles and deploy countermeasures such as jamming the missiles' infrared tracking systems.
Gong had been hired in January 2023 as a design manager overseeing application-specific integrated circuits (ASICs) for infrared sensors.
Between 30 March and 26 April 2023, the DOJ said he copied over 3,600 files from his work laptop to personal devices, including more than 1,800 after he had accepted the rival job. Many documents were labelled 'Proprietary Information' and 'Export Controlled.'
The files contained proprietary information related to advanced readout integrated circuits used in missile launch detection systems and low-visibility threat tracking in military aircraft.
Some files outlined blueprints for 'next-generation' sensors capable of identifying low-observable targets with enhanced survivability in space, along with engineering schematics for cryogenic sensor housing.
Officials described the stolen data as some of the company's most valuable trade secrets, worth hundreds of millions of dollars.
Separately, between 2014 and 2022, the accused had submitted several applications to Chinese state-run 'Talent Programmes' designed to recruit experts in sensitive fields.
The DOJ said Gong sought to develop military-grade analogue-to-digital converters and low-light image sensors for night-vision systems. In one 2020 application, Gong submitted a video referencing proprietary sensor models from a defence firm he had previously worked at.
Prosecutors also cited a 2019 email in which Gong said he had 'taken a risk' by participating in the programmes due to his ties to the US defence industry but believed he could contribute to China's military chip design capabilities.

CBI busts international cyber fraud; raids illegal Call Centre in Pune; 3 arrested
The Central Bureau of Investigation (CBI) busted a cyber fraud and financial crime syndicate operating out of Pune and Mumbai that targeted foreign nationals — particularly American citizens — through impersonation, phishing calls, and financial deception. CBI registered a case on Thursday against 'unknown public servants of Banks and four private persons' for allegedly 'running an illegal call centre in Pune, operating since January 2025' in the form of a well-organised criminal conspiracy. So far the CBI has arrested three persons in this case. They were produced before a special court for CBI cases in Mumbai. The court remanded the three to police custody till July 30. As per a press release issued by the CBI on Friday, the fraudsters impersonated officials from agencies such as the 'U.S Internal Revenue Service (IRS), U.S. Citizenship and Immigration Services (USCIS), and even the Indian High Commission' to defraud unsuspecting US citizens. 'Under the threat of legal action, the victims were coerced into paying amounts ranging from $ 500 to $ 3,000 through gift cards or Bitcoin transfers. Spoofed VoIP-based calls were being made from a covertly operated illegal Call Centre situated at Pune,' the press release mentioned. CBI probe into this case revealed that the illegally earned proceeds, estimated to be around Rs 4 crore monthly, were laundered via mule accounts, cryptocurrency, and hawala routes. According to the CBI, the fraudulent operations were found to be supported by certain unknown public and private sector bank officials, who facilitate the opening and operation of fake accounts using forged KYC documents, violating established RBI and institutional guidelines. Probe also revealed that workers at the Call Centre used for the scam are paid in cash routed via hawala channels from both the U.S. and domestic locations, including Maharashtra and Gujarat. These workers are housed in multiple residential flats across Pune. 'The scam's operation includes the illegal acquisition of contact leads through vendors on messaging platforms such as WhatsApp and Signal. Victims are contacted via toll-free numbers generated and disseminated by these vendors, eventually connecting them to the fraudulent call centre,' the press release stated. After the case was registered, CBI teams conducted searches at seven places linked to the accused or their associates. CBI also raided and searched the illegal call centre run by the accused persons at Pune. CBI seized digital devices like 27 mobile phones, 17 laptops and other incriminating material from the accused persons and their associates at the Pune call centre. 'Scrutiny of these mobile phones and laptops revealed that the accused persons were using caller services found on social media platforms like Signal and WhatsApp. Besides, unexplained cash of Rs.1.6 lakhs and around 150 gram narcotic substance was also seized from the residence of one of the accused… Scrutiny of the mobile phone of an accused has revealed that he has crypto currency worth Rs.6.94 lakh in his wallet. During the search at the residence of another accused unexplained cash of Rs.9.60 lakh was recovered' the press release stated.

2 Tripura profs suspended for ‘inappropriate conduct'
Agartala: The state govt has suspended two assistant professors from separate degree colleges following allegations of misconduct. The action was taken on Friday against Dr Shantanu Mujumdar, a chemistry professor at Kamalpur Government Degree College, and Dr Abhijit Nath, a physics professor at Ram Thakur College in Agartala. Dr Mujumdar's suspension comes after a video surfaced on social media, allegedly showing him in a compromising situation with a female student inside the college laboratory. Special secretary for education Ravel Hemendra Kumar said Dr Mujumdar admitted to the inappropriate conduct, which violated the institution's sanctity and the teaching profession's dignity. He has been directed to report to the principal of Ishwar Chandra Vidyasagar College in South Tripura and is prohibited from leaving the station without prior approval. In a separate incident, Dr Nath faces suspension over allegations of tampering with the college's admission process. An inquiry revealed that he forged the admission of students not listed on the merit list by using fee cards with falsified principal signatures. Dr Nath confessed to taking 50 fee cards from the office without authorization, returning only 28, and failing to account for the rest. The college principal reported that Dr Nath facilitated 69 unauthorized admissions using 120 fee cards. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo Both professors have been suspended with immediate effect and are required to remain at their respective headquarters unless granted permission to leave.

HC upholds AMC's decision to sack four fire officers
Ahmedabad: The Gujarat high court on Friday upheld the Ahmedabad Municipal Corporation's (AMC) decision to terminate the services of four fire officers who had secured their jobs using forged documents. The officers had allegedly submitted fake sponsorship letters to gain admission into a mandatory training course at the National Fire Service College (NFSC), Nagpur. The AMC assured the court that similar action would be taken against other fire officials who gained employment through the same fraudulent means. The controversy surfaced following a vigilance probe, which revealed that the sponsorship letters submitted by several appointees for NFSC admission were forged. Based on this, the AMC terminated their services last year. The dismissed officials challenged the decision in the high court, and a single judge had quashed the termination orders.

A division bench of Justices A S Supehia and R T Vachhani ruled that the appointments were "void ab initio". by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo Citing the legal doctrine sublato fundamento cadit opus (if the foundation is removed, the structure falls), the court stated that appointments based on fraud cannot be legitimized. The dismissed officers claimed discrimination, arguing that others who used similar means had not been penalized. However, the court rejected this argument, observing: "The concept of 'equality', as envisaged under Article 14 of the Constitution, is a positive concept which cannot be enforced in a negative manner. Hence, the punishment cannot be set aside on the ground of discrimination." The court also recorded AMC's assurance, through its counsel advocate Virk, that action would be taken against all employees who had submitted fake sponsorship letters.
