Several Russia-based news outlets are reporting that Yevgeny Prigozhin is shutting down his Patriot media company in the aftermath of his failed mutiny at the head of the Wagner PMC last month.

The Patriot media group is a holding company for a dozen of Russian-language propaganda and fake news sites, such as RIA FAN, Politika Segodnya (Politics Today), Ekonomika Segodnya (Economics Today), Nevskiye Novosti (Nevsky News), and Narodnye Novosti (People's News). It is also the holding company for the Internet Research Agency—Russia's infamous "troll farm" linked to multiple instances of election interference across the world.

Prigozhin has allegedly fired all employees and plans to shut down all news sites. All this information comes from Patriot media group insiders, and Prigozhin has not made a formal statement or has been seen or heard from since leaving Russia for Belarus.

News of the Patriot group's collapse is not surprising and was to be expected in light of Prigozhin's mutiny last month.

Russian telecommunications watchdog Roskomnadzor has been blocking access to all Patriot news sites inside Russia since the day of Prigozhin's Wagner rebellion on June 23.

There have also been reports that police forces raided some of Patriot's Sankt Petersburg offices on the same day.

Rumors also emerged the group might change ownership, with Yury Kovalchuk, the owner of the National Media Group (NMG), being the favorite to take over the Patriot group.

Despite the shutdowns, a change of ownership might very well happen since all it takes is moving some domains from one DNS to another. The Russian government will surely not give up on a program that has been so incredibly successful. If assets are moved to a new media group or if a new organization is built from the ground is irrelevant. Regardless, at this point, it is safe to say Prigozhin's time as the head of Russia's propaganda machine is 100% over.

Prigozhin was previously charged in 2018 in the US for his role in running the Internet Research Agency and meddling in the 2016 US Presidential Election. He initially denied any association with the IRA but admitted and later gloated about the organization's success after Russia's invasion of Ukraine.

Back in March 2023, a consortium of investigative journalists published an analysis of the Wagner Leaks, a collection of files stolen from Prigozhin's many public companies. The leaks covered the Wagner PMC, the IRA, and the Concord group of consulting companies.

Breaches, hacks, and security incidents

TSMC denies ransomware attack: Taiwanese chipmaker TSMC has denied suffering a ransomware attack after the LockBit gang listed the company on its dark web leak site. The company says LockBit hit one of its suppliers, and its IT network is safe. LockBit had asked for a $70 million ransom payment. That's definitely not gonna happen any time soon.

DoZoR confirms hack: Russian satellite communications operator DoZoR-Teleport has confirmed a destructive cyber-attack that hit its systems last week. The company says the incident impacted infrastructure hosted with one of its cloud service providers, but did not name the operator. Dozor-Teleport general director Alexander Anosov says it may take up to two weeks to restore affected services. The company provides satellite connectivity to some of Russia's largest organizations, such as Gazprom, Rosatom, the FSB, and Moscow's regional government.

Japan scolds Fujitsu: The Japanese government has publicly criticized Fujitsu for failing to detect a data breach for more than eight months. The incident impacted the company's FENICS service, a cloud platform used by the Japanese private sector and government agencies. The platform was compromised in March 2022 after attackers discovered a misconfiguration in some of its services. It took Fujitsu months to spot the intruder's backdoors, with the company disclosing the breach in December. Japanese officials believe the hack was the work of Chinese state-sponsored hackers, making it the third time they targeted a Fujitsu product over the last two years. [Additional coverage in Nikkei]

Huobi incident: Huobi, one of the world's largest cryptocurrency exchanges, quietly fixed a major security breach that could have granted an attacker access to the company's cloud infrastructure. Researchers say the company leaked a set of AWS credentials that could have allowed an attacker to gain write privileges to all of their S3 buckets. Now, that's quite the fail!

"An attacker exploiting Huobi's mistakes would have had the opportunity to carry out the largest crypto theft in history. The company has previously reported handling over a billion dollars a day in trading volume."

USAA incident: The United Services Automobile Association has disclosed a security breach caused by an employee sharing their USAA credentials with a third party. USAA says the breach lasted between December 20, 2022, and May 18, 2023 [See data breach notification letter here/PDF].

Poly Network crypto-heist: A threat actor has stolen $4.39 million worth of crypto-assets from cross-chain platform PolyNetwork. The company has suspended operations in the aftermath of the recent attack. This marks the second time the platform has been hacked. It previously lost $610 million worth of crypto-assets in August 2021 in one of the biggest crypto-heists of all time. [Additional coverage in CoinDesk]

Akira ransomware decrypter: Avast has released a free decrypter for the Akira ransomware, allowing victims to recover their files without paying the attackers. The Akira ransomware launched operations in March 2023 and has versions of both Windows and Linux. The free decrypter only covers Windows variants, and Avast says it's working on a Linux decrypter as well. In the meantime, Avast says files encrypted on Linux hosts can be moved to a Windows machine and have them decrypted there using its Windows decryption toolkit.

Proxyjacking campaign: Akamai researchers have uncovered a cybercrime operation where a threat actor has been hacking into vulnerable servers and secretly enlisting them into peer-to-peer (P2P) proxy networks in order to monetize their bandwidth for personal profits. The intrusions take place via misconfigured SSH services, and that compromised servers are typically enrolled in services such as Peer2Proxy or Honeygain.

Malvertising campaign: Trend Micro says it has seen BlackCat ransomware infections originating from malvertising campaigns promoting a malware-laced version of the WinSCP app. We're so glad Google Ads is living up to its full potential.

Vulnerabilities, security research, and bug bounty

WP plugin exploitation: Wordfence is seeing a threat actor launch active attacks against WordPress sites running the Ultimate Member plugin. The plugin is installed on more than 200,00 WordPress sites. Wordfence says the attacker is exploiting an older vulnerability that was not adequately patched.

D-Link PoC: Andisec researchers have published details and a PoC for CVE-2023-26615, a password-reset vulnerability in D-Link DIR-823G routers. The vulnerability allows unauthorized attackers to reset the password for the router's web management panel.

Citrix XSS: Assetnote researchers have published details on an XSS vulnerability (CVE-2023-24488) in the Citrix Gateway. More than 50,000 such devices are currently available online. Citrix patched this back in May.

GitLab vulnerability: Juniper has published a detailed write-up on CVE-2023-2825, a 10/10 vulnerability that GitLab patched back in May. A PoC for this was released back in May.

VMWare Aria vulnerability: ZDI has published a detailed technical write-up on CVE-2023-20864, an insecure deserialization vulnerability in VMware Aria Operations for Logs. ZDI likened the bug to CVE-2023-20887, another bug in the same software that is currently exploited in the wild.

XORtigate patch status: Security firm BishopFox says it developed an internal exploit for a recent Fortinet zero-day known as XORtigate (CVE-2023-27997). The company says it found more than 490,000 affected SSL VPN interfaces exposed on the internet, of which roughly 69% are still unpatched for the XORtigate vulnerability. The company previously released a tool that could scan FortiGate SSL VPN instances and see if they are vulnerable to XORtigate.

Attack on MongoDB Queryable Encryption: A team of academics from ETH Zurich has devised an attack technique that can recover plaintext data from encrypted MongoDB databases. The attack targets Queryable Encryption, a new feature launched last year that allows a MongoDB database to run queries on encrypted data. Researchers say the attack exploits the current interaction between MongoDB's QE feature and the database's logging system. The team notified MongoDB of their findings. The company said they would not be fixing any issues since the QE feature was in preview and would eventually change in future versions, invalidating the attack. Researchers said the attack still worked in February 2023 when they last tested it. More in the research team's paper [PDF].
