Major Security Flaws Expose Keystrokes of Over 1 Billion Chinese Keyboard App Users

Major Security Flaws Expose Keystrokes of Over 1 Billion Chinese Keyboard App Users
Apr 24, 2024 Encryption / Mobile Security
Security vulnerabilities uncovered in cloud-based pinyin keyboard apps could be exploited to reveal users' keystrokes to nefarious actors. The findings come from the Citizen Lab, which discovered weaknesses in eight of nine apps from vendors like Baidu, Honor, iFlytek, OPPO, Samsung, Tencent, Vivo, and Xiaomi. The only vendor whose keyboard app did not have any security shortcomings is that of Huawei's. The vulnerabilities could be exploited to "completely reveal the contents of users' keystrokes in transit," researchers Jeffrey Knockel, Mona Wang, and Zoë Reichert  said . The disclosure builds upon prior research from the interdisciplinary laboratory based at the University of Toronto, which identified  cryptographic flaws  in Tencent's Sogou Input Method last August. Collectively, it's estimated that close to one billion users are affected by this class of vulnerabilities, with Input Method Editors (IMEs) from Sogou, Baidu, and iFlytek accounting fo

Police Chiefs Call for Solutions to Access Encrypted Data in Serious Crime Cases

Police Chiefs Call for Solutions to Access Encrypted Data in Serious Crime Cases
Apr 23, 2024 End-to-End Encryption / Privacy
European Police Chiefs said that the complementary partnership between law enforcement agencies and the technology industry is at risk due to end-to-end encryption (E2EE). They called on the industry and governments to take urgent action to ensure public safety across social media platforms. "Privacy measures currently being rolled out, such as end-to-end encryption, will stop tech companies from seeing any offending that occurs on their platforms," Europol  said . "It will also stop law enforcement's ability to obtain and use this evidence in investigations to prevent and prosecute the most serious crimes such as child sexual abuse, human trafficking, drug smuggling, homicides, economic crime, and terrorism offenses." The idea that E2EE protections could stymie law enforcement is often referred to as the  "going dark" problem , triggering concerns it could create  new obstacles  to gather evidence of nefarious activity. The development comes ag

GenAI: A New Headache for SaaS Security Teams

GenAI: A New Headache for SaaS Security Teams
Apr 17, 2024SaaS Security / AI Governance
The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

Akira Ransomware Gang Extorts $42 Million; Now Targets Linux Servers
Apr 19, 2024 Ransomware / Endpoint Security
Threat actors behind the Akira ransomware group have extorted approximately $42 million in illicit proceeds after breaching the networks of more than 250 victims as of January 1, 2024. "Since March 2023, Akira ransomware has impacted a wide range of businesses and critical infrastructure entities in North America, Europe, and Australia," cybersecurity agencies from the Netherlands and the U.S., along with Europol's European Cybercrime Centre (EC3),  said  in a joint alert. "In April 2023, following an initial focus on Windows systems, Akira threat actors deployed a Linux variant targeting VMware ESXi virtual machines." The double-extortion group has been observed using a C++ variant of the locker in the early stages, before shifting to a Rust-based code as of August 2023. It's worth noting that the e-crime actor is  completely different  from the Akira ransomware family that was active in 2017. Initial access to target networks is facilitated by means o

Critical Atlassian Flaw Exploited to Deploy Linux Variant of Cerber Ransomware

Critical Atlassian Flaw Exploited to Deploy Linux Variant of Cerber Ransomware
Apr 17, 2024 Encryption / Vulnerability
Threat actors are exploiting unpatched Atlassian servers to deploy a Linux variant of Cerber (aka C3RB3R) ransomware. The attacks leverage  CVE-2023-22518  (CVSS score: 9.1), a critical security vulnerability impacting the Atlassian Confluence Data Center and Server that allows an unauthenticated attacker to reset Confluence and create an administrator account. Armed with this access, a threat actor could take over affected systems, leading to a full loss of confidentiality, integrity, and availability. According to cloud security firm Cado, financially motivated cybercrime groups have been observed abusing the newly created admin account to install the Effluence web shell plugin and allow for the execution of arbitrary commands on the host. "The attacker uses this web shell to download and run the primary Cerber payload," Nate Bill, threat intelligence engineer at Cado,  said  in a report shared with The Hacker News. "In a default install, the Confluence applicati

Widely-Used PuTTY SSH Client Found Vulnerable to Key Recovery Attack

Widely-Used PuTTY SSH Client Found Vulnerable to Key Recovery Attack
Apr 16, 2024 Encryption / Network Security
The maintainers of the  PuTTY Secure Shell (SSH) and Telnet client  are alerting users of a critical vulnerability impacting versions from 0.68 through 0.80 that could be exploited to achieve full recovery of NIST P-521 (ecdsa-sha2-nistp521) private keys. The flaw has been assigned the CVE identifier  CVE-2024-31497 , with the discovery credited to researchers Fabian Bäumer and Marcus Brinkmann from the Ruhr University Bochum. "The effect of the vulnerability is to compromise the private key," the PuTTY project  said  in an advisory. "An attacker in possession of a few dozen signed messages and the public key has enough information to recover the private key, and then forge signatures as if they were from you, allowing them to (for instance) log in to any servers you use that key for." However, in order to obtain the signatures, an attacker will have to compromise the server for which the key is used to authenticate to. In a message posted on the Open Source

Considerations for Operational Technology Cybersecurity

Considerations for Operational Technology Cybersecurity
Apr 04, 2024 Operational Technology / Cybersecurity
Operational Technology (OT)  refers to the hardware and software used to change, monitor, or control the enterprise's physical devices, processes, and events. Unlike traditional Information Technology (IT) systems, OT systems directly impact the physical world. This unique characteristic of OT brings additional cybersecurity considerations not typically present in conventional IT security architectures. The convergence of IT and OT Historically, IT and Operational Technology (OT) have operated in separate silos, each with its own set of protocols, standards, and cybersecurity measures. However, these two domains are increasingly converging with the advent of the Industrial Internet of Things (IIoT). While beneficial in terms of increased efficiency and data-driven decision-making, this convergence also exposes OT systems to the same cyber threats that IT systems face. Unique Cybersecurity Considerations for OT Real-time requirements Operational Technology systems often opera

Apr 01, 2024 Mobile Security / Data Privacy
The Android banking trojan known as Vultur has resurfaced with a suite of new features and improved anti-analysis and detection evasion techniques, enabling its operators to remotely interact with a mobile device and harvest sensitive data. "Vultur has also started masquerading more of its malicious activity by encrypting its C2 communication, using multiple encrypted payloads that are decrypted on the fly, and using the guise of legitimate applications to carry out its malicious actions," NCC Group researcher Joshua Kamp  said  in a report published last week. Vultur was  first disclosed  in early 2021, with the malware capable of leveraging Android's accessibility services APIs to execute its malicious actions. The malware has been observed to be  distributed via trojanized dropper apps  on the Google Play Store, masquerading as authenticator and productivity apps to trick unwitting users into installing them. These dropper apps are offered as part of a dropper-as-a

Mar 28, 2024 Linux / Network Security
A Linux version of a multi-platform backdoor called  DinodasRAT  has been detected in the wild targeting China, Taiwan, Turkey, and Uzbekistan,  new findings  from Kaspersky reveal. DinodasRAT, also known as XDealer, is a C++-based malware that offers the ability to harvest a wide range of sensitive data from compromised hosts. In October 2023, Slovak cybersecurity firm ESET  revealed  that a governmental entity in Guyana had been targeted as part of a cyber espionage campaign dubbed Operation Jacana to deploy the Windows version of the implant. Then last week, Trend Micro  detailed  a threat activity cluster it tracks as Earth Krahang and which has shifted to using DinodasRAT since 2023 in its attacks aimed at several government entities worldwide. The use of DinodasRAT has been attributed to various China-nexus threat actors, including  LuoYu , once again reflecting the tool sharing prevalent among hacking crews identified as acting on behalf of the country.

Alert: New Phishing Attack Delivers Keylogger Disguised as Bank Payment Notice
Mar 27, 2024 Vulnerability / Cybercrime
A new phishing campaign has been observed leveraging a novel loader malware to deliver an information stealer and keylogger called  Agent Tesla . Trustwave SpiderLabs said it identified a phishing email bearing this attack chain on March 8, 2024. The message masquerades as a bank payment notification, urging the user to open an archive file attachment. The archive ("Bank Handlowy w Warszawie - dowód wpłaty_pdf.tar.gz") conceals a malicious loader that activates the procedure to deploy Agent Tesla on the compromised host. "This loader then used obfuscation to evade detection and leveraged polymorphic behavior with complex decryption methods," security researcher Bernard Bautista  said  in a Tuesday analysis. "The loader also exhibited the capability to bypass antivirus defenses and retrieved its payload using specific URLs and user agents leveraging proxies to further obfuscate traffic." The tactic of embedding malware within seemingly benign files is
