Chinese state-backed hackers broke into a computer network that’s used by the Dutch armed forces by targeting Fortinet FortiGate devices. “This [computer network] was used for unclassified research and development (R&D),” the Dutch Military Intelligence and Security Service (MIVD) said in a statement. “Because this system was self-contained, it did not lead to any damage […]
A new variant of a remote access trojan called Bandook has been observed being propagated via phishing attacks with an aim to infiltrate Windows machines, underscoring the continuous evolution of the malware. Fortinet FortiGuard Labs, which identified the activity in October 2023, said the malware is distributed via a PDF file that embeds a link […]
Microsoft Word documents exploiting known remote code execution flaws are being used as phishing lures to drop malware called LokiBot on compromised systems. “LokiBot, also known as Loki PWS, has been a well-known information-stealing Trojan active since 2015,” Fortinet FortiGuard Labs researcher Cara Lin said. “It primarily targets Windows systems and aims to gather sensitive […]
Cybersecurity researchers have shared the inner workings of an Android malware family called Fluhorse. The malware “represents a significant shift as it incorporates the malicious components directly within the Flutter code,” Fortinet FortiGuard Labs researcher Axelle Apvrille said in a report published last week. Fluhorse was first documented by Check Point in early May 2023, […]

Fortinet has released patches to address a critical security flaw in its FortiGate firewalls that could be abused by a threat actor to achieve remote code execution. The vulnerability, tracked as CVE-2023-27997, is “reachable pre-authentication, on every SSL VPN appliance,” Lexfo Security researcher Charles Fol, who discovered and reported the flaw, said in a tweet […]
Threat actors are actively exploiting an unpatched five-year-old flaw impacting TBK digital video recording (DVR) devices, according to an advisory issued by Fortinet FortiGuard Labs. The vulnerability in question is CVE-2018-9995 (CVSS score: 9.8), a critical authentication bypass issue that could be exploited by remote actors to gain elevated permissions. “The 5-year-old vulnerability (CVE-2018-9995) is […]
A new “all-in-one” stealer malware named EvilExtractor (also spelled Evil Extractor) is being marketed for sale for other threat actors to steal data and files from Windows systems. “It includes several modules that all work via an FTP service,” Fortinet FortiGuard Labs researcher Cara Lin said. “It also contains environment checking and Anti-VM functions. Its […]
Critical security flaws in Cacti, Realtek, and IBM Aspera Faspex are being exploited by various threat actors in hacks targeting unpatched systems. This entails the abuse of CVE-2022-46169 (CVSS score: 9.8) and CVE-2021-35394 (CVSS score: 9.8) to deliver MooBot and ShellBot (aka PerlBot), Fortinet FortiGuard Labs said in a report published this week. CVE-2022-46169 relates […]
Government entities and large organizations have been targeted by an unknown threat actor by exploiting a security flaw in Fortinet FortiOS software to result in data loss and OS and file corruption. “The complexity of the exploit suggests an advanced actor and that it is highly targeted at governmental or government-related targets,” Fortinet researchers Guillaume […]
