BSI, the German cybersecurity agency, took down this week a web server used to control malware deployed by the Iranian government to spy on participants of recent anti-government protests.
The server was identified over the weekend by Hamid Kashfi, a security engineer at Trail Of Bits, who confirmed a tip that the Islamic Revolutionary Guard Corps, a branch of the Iranian military, was manually installing malware on the devices of detained anti-government protesters.
Kashfi obtained multiple copies of the malware—which he later identified as a version of the L3MON Android remote access trojan—and found that all samples were communicating with a VPS server based in Germany, on which the BSI acted this week.
The researcher is now warning that even if this server is now down, the danger to protesters continues, as IRGC operators are most likely to set up a new one for subsequent deployments.
Iranians detained by the IRCG are advised to reset their smartphones as Kashfi says that the L3MON RAT has no advanced persistence capabilities, and this will remove it from compromised devices.

Government, politics, and policy
BSI chief dismissed: The German Interior Ministry dismissed the chief of its national cybersecurity agency, the BSI. Arne Schoenbohm was sacked after German media found suspected ties to Russia's intelligence services in one of his past private sector endeavors. Officials didn't confirm the reports but said Schoenbohm "damaged the necessary confidence of the public in the neutrality and impartiality" of the BSI. Schoenbohm has been leading the BSI since February 2016.
Israel backdoored the Netherlands' wiretapping system: Guilhem Giraud, a former employee of the French internal security service DGSI, revealed in a book published last month that during a visit for exchange of experience in 2006 with their Dutch counterparts, Dutch officials revealed that they found a backdoor in equipment supplied by an Israeli vendor to the country's Driebergen communications wiretapping center. Giraud said the 2006 visit and the candid disclosure from Dutch officials was one of the reasons why French authorities built the PNIJ interception platform using only homemade systems, taking what he described as a "no Israeli suppliers" approach. After the book made some waves in the Netherlands last week, a spokesperson for the Dutch government rebuffed Giraud and told local newspaper de Volkskrant that the backdoor story was just "nonsense."
CYBERCOM cleans its network: US CYBERCOM said it executed what the agency described as a global cyberspace defensive operation earlier this month between October 3 and 14.

Cybercrime and threat intel
Car hackers arrested: Europol said authorities in France, Spain, and Latvia have detained 31 suspects and dismantled a car thief ring that used malicious software to hijack key fobs and steal vehicles. Europol said the group used a special tool that targeted keyless vehicles from two French car manufacturers. The tool was marketed online as an automotive diagnostic solution, allowing owners to replace a car's original software but also allowed to open doors and start the vehicle without the actual key fob. Europol said it detained the tool's developers, resellers, and the car thieves who used it.
Bulgaria seeks Russian hacker: Bulgaria's prosecutor's office charged and is seeking the extradition of a Russian citizen for launching a series of DDoS attacks against government websites earlier over the weekend. Desislava Petrova, the Sofia City Prosecutor's Office spokesperson, said Russian authorities were not complying with their request (shocker!) and that they were most likely also involved in the attack as well.
South Korea takes down scam site: The South Korean Ministry of Science and ICT said on Monday that it took down a malicious website that was using the nationwide confusion caused by a major fire at one of KakaoTalk's data centers to distribute malware to users impacted by the downtime.
Loan forgiveness scams: With news that the Biden administration is preparing to forgive some student loans, the FBI published a warning this week about the potential email, phone, and web scams that may arise in the coming months. The FBI said scammers would most likely try to obtain personally identifiable information, financial information, or payment from US citizens who are eligible for student loan forgiveness, and the agency reminded everyone that the US government does not intend to charge any processing fees for this process.
Reporter accuses law firm of hacking: Former WSJ reporter Jay Solomon has accused Philadelphia-based law firm Dechert LLP of hiring Indian hackers to compromise his email account and using the stolen information to have him fired. Solomon's public statement comes after Iranian-American aviation executive Farhad Azima, one of his former sources, also sued the same law firm last week, together with a New York City public relations company and an Israeli private investigator, accusing the three of conspiring to hack his email account and tamper with witnesses part of ongoing litigation, and even leak information to the press.

Malware technical reports
Gafgyt: SecurityScorecard malware analyst Vlad Pasca published a report this week on the Gafgyt IoT malware strain, also known as Bashlite.
APTs and cyber-espionage
Spyder Loader: Broadcom Symantec researchers said they spotted new attacks part of Operation CuckooBees. But unlike previous attacks, where this Chinese threat actor went after intellectual property, the new attacks targeted Hong Kong organizations with a version of the Spyder Loader malware.
"The victims observed in the activity seen by Symantec were government organizations, with the attackers remaining active on some networks for more than a year. We saw the Spyder Loader (Trojan.Spyload) malware deployed on victim networks, indicating this activity is likely part of that ongoing campaign."
APTs went after Zimbra: Kaspersky researchers said in a blog post last week that they've seen multiple APT groups exploiting a recently disclosed Zimbra zero-day (CVE-2022-41352), and that one of these groups has been "systematically infecting all vulnerable servers in Central Asia." In the meantime, after leaving the vulnerability unpatched for almost a month, Zimbra has finally delivered a patch.
Vulnerabilities and bug bounty
Zimbra zero-day: As mentioned in a section above, Zimbra has finally released a patch for a zero-day (CVE-2022-41352) that has been under active exploitation for more than a month.
ProxyRelay: Security researcher Orange Tsai published details on ProxyRelay, the fourth major vulnerability he found in Exchange servers. His previous findings include well-known vulnerabilities like ProxyLogon, ProxyOracle, and ProxyShell.
Much ado about nothing: A recently disclosed vulnerability in the Apache Commons Text library (tracked as CVE-2022-42889) has been widely described as the next Log4Shell disaster, but a more in-depth analysis by Rapid7 reveals that this assessment is only misplaced hype.
Git security updates: The Git Project released security updates for the Git versioning system this week. GitHub said none of these issues affect its service.
Oracle CPU: The quarterly Oracle security updates are out, with patches for 370 vulnerabilities.
Magento patch warning: Web security firm Sansec warned users of the Magento e-commerce platform to look into upgrading their online stores to the latest version of the CMS rather than install a security hotfix patch released for older versions.
MagSound attack: A team of academics from the Hong Kong Polytechnic University published details about MagSound [PDF], an attack that uses magnetic interference induced by a wireless charger to send malicious voice commands to a smartphone. Since the voice commands are created using magnetic waves, they are also inaudible to humans.
"Essentially, we show that the microphone components of smart devices suffer from severe magnetic interference when they are enjoying wireless charging, due to the absence of effective protection against the EMI at low frequencies (100 kHz or below). By taking advantage of this vulnerability, we design two inaudible voice attacks, HeartwormAttack and ParasiteAttack, both of which aim to inject malicious voice commands into smart devices being wirelessly charged. They make use of a compromised wireless charger or accessory equipment (called parasite) to inject the voice, respectively. We conduct extensive experiments with 17 victim devices (iPhone, Huawei, Samsung, etc.) and 6 types of voice assistants (Siri, Google STT, Bixby, etc.). Evaluation results demonstrate the feasibility of two proposed attacks with commercial charging settings."
