In news that you never heard before—Bitcoin ATMs have been getting hacked across the world after a mysterious threat actor discovered a zero-day vulnerability in the ATM's web-based admin management panel.
The attacks, which appear to have been taking place since the start of the month, have been targeting Bitcoin ATMs managed via Crypto Application Server (CAS), a cloud-based system from Panama-based company General Bytes.
In a security alert published on Friday, the company said the attackers scanned the internet to identify CAS servers and then accessed a left-over URL from the CAS installation process. This URL allowed them to re-register the admin panel's default admin user using their own credentials; access they later used to change ATM settings so every time a user would send money to an ATM to be picked up using an in-person transaction, the funds would be automatically redirected to the attacker's wallets.
General Bytes said all CAS servers released over the past two years are vulnerable (since CAS version 20201208). The company said it released patches that should address the vulnerability exploited in the attacks.
According to BleepingComputer, there were 18 General Bytes CAS servers still exposed online last week, but more are believed to be hidden behind firewalls since the attacks were first reported.
General Bytes said the attacks against its ATMs started three days after it added a "Help Ukraine" feature to its machines earlier this month.
Breaches and hacks
Airplane Accelerates leak: CyberNews says it found 626GB of customer data in an unsecured Elasticsearch server belonging to Airplane Accelerates, a free VPN service advertised to Chinese users. The data contained a staggering of 5.7 billion entries, including user IDs, what IP addresses users were connecting to and from, domain names, and timestamps, the news outlet reported.
Failed crypto-heist: Cryptocurrency bridge project Celer said it successfully fended off a cyber-attack after a threat actor attempted a DNS hijacking account against its frontend infrastructure.
General tech and privacy
Warning about in-app browsers: Privacy expert Felix Krause has published two write-ups over the past week warning about the dangers of using a mobile app's built-in browser as compared to standalone browsers. In a first report, Krause said he found that the Facebook and Instagram in-app browsers were tracking users on all the sites they visited, while in a second, he said he found key-logging code in TikTok's in-app browser, although he did not find any evidence that it was being actively used.
Government, politics, and policy
VIASAT hack impact in France: According to the minutes of a closed-doors meeting held by Stéphane Bouillon, Secretary General of Defense and National Security for the French Parliament's National Assembly, the Russian hack of the VIASAT satellite internet network had "affected" French ambulance (phone number: 15) and firefighting (phone number: 18) emergency services. The extent of the impact was not detailed. (h/t @SwitHak)
DOD browsing history purchases: The National Defense Authorization Act, a bill passed by the US House in July, which authorizes Department of Defense (DOD) activities and expenses for fiscal year 2023, also includes a clause that will require the DOD to disclose any purchases of smartphone or web browsing data if such purchases target American citizens, according to Gizmodo. The bill still needs to pass the US Senate. The initiative comes after Congress also began looking into similar purchases made by US law enforcement agencies as well, as officials seem to want to crack down on the use of such data, or at least get some visibility into how agencies are using such data, which until now has been used outside of most oversight mechanisms.
NSO CEO steps down: Shalev Hulio, the CEO of embattled spyware maker NSO Group, will step down from his role, the company announced on Sunday. According to Reuters, COO Yaron Shohat will be appointed to oversee a reorganization of the company before a successor is named. This marks the second time that Hulio resigned as NSO CEO after he also resigned in October 2021 but was forced to come back after his replacements left shortly after being brought on board. The company is also rumored to be preparing to sack around 100 employees as well.
Russia looking at more misbehaving companies: Roskomnadzor said it is looking at companies like TikTok, Telegram, Zoom, Discord, and Pinterest after the companies refused to remove "prohibited" content, most likely in relation to Russia's invasion of Ukraine. Since its invasion of Ukraine, Russia has slowly cracked down on the Tor Project, VPN providers, Facebook sites, Twitter, Twitch, and many others.
Russia may compensate victims who had their data leaked: The Russian Ministry of Digital Development is considering an initiative to provide some sort of financial compensation to Russian citizens who had their data leaked online. Kommersant reports that the funds for these payments may come from the companies who leaked the data; in the form of fines the ministry might impose.

Cybercrime and threat intel
LockBit gets DDOSed: After the LockBit ransomware gang took credit for the ransomware attack against security firm Entrust, the gang's servers have been flooded by DDOS attacks with messages of "DELETE_ENTRUSTCOM_[REDACTED]" — referencing that LockBit operators should delete the Entrust entry and its data from their leak site.
Desorden Group: In a report last week, CyberInt said they'd seen the Desorden Group list several Thai entities as victims of their intrusions. Desorden is a threat actor that was first spotted last year and which operates by breaching organizations, stealing their data, and trying to extort a ransom payment from victims.
Pitraix botnet: An unknown developer has open-sourced a new Go-based P2P botnet named Pitraix that works via Tor and can self-modify with every new infection. Add your detections, folks!
Cryptominers on npm and PyPI: Sonatype researchers have found another batch of malicious packages uploaded on the npm and PyPI portals. This time, they found more than 200 libraries, all configured to install cryptominers on infected hosts. These findings come after several similar incidents were reported last week [1, 2, 3, 4, 5].
Attacks on LEAs: In a report published on Friday, Resecurity said it observed multiple dark web marketplaces where cybercriminals have sold accounts and credentials belonging to police officers of various foreign countries (emails, VPNs, SSO, etc.).
New FBI PIN alert: The FBI published a new private industry notification (PIN) on Thursday, warning US organizations of the use of proxy servers to carry out credential stuffing attacks. As a way to counter these threats, the FBI recommends using MFA on vulnerable accounts and educating users about the dangers of reusing passwords. More here [PDF].
Tox as a C&C mechanism: Researchers from cloud security firm Uptycs said they have begun seeing the Tox P2P serverless instant messaging system used as a command and control mechanism for some cryptomining operations.
New domain-fronting technique: The team behind Shell.Systems have published a report on a new domain-fronting technique abused in the wild to hide malicious traffic. The technique relies on abusing the services of tyk.io, a cloud-native API management platform used by a lot of applications worldwide to manage their API calls via the cloud. According to Vitali Kremez, CEO of AdvIntel, many former members of the Conti ransomware group are currently abusing this technique.
Malware technical reports

APTs and cyber-espionage
Kasablanka: Qihoo 360 researchers have published a report on new campaigns carried out by the Kasablanka threat actor targeting Bangladesh. Cisco Talos researchers believe this group is based in Morocco, which is why it is referred to as "Kasablanka."
