As many as 85 command-and-control servers have been discovered supported by the ShadowPad malware since September 2021, with infrastructure detected as recently as October 16, 2022. That's according to VMware's Threat Analysis Unit, which studied three ShadowPad variants using TCP, UDP, and HTTP(S) protocols for C2 communications.
The exploits, dubbed LogCrusher and OverLog by Varonis, take aim at the EventLog Remoting Protocol, which enables remote access to event logs. While the former allows "Any domain user to remotely crash the Event Log application of any Windows machine," OverLog causes a DoS by "Filling the hard drive space of any Windows machine on the domain," Dolev Taler said in a report shared with The Hacker News.
Cybersecurity researchers have shared more details about a now-patched security flaw in Azure Service Fabric Explorer (SFX) that could potentially enable an attacker to gain administrator...
New research has disclosed what's being called a security vulnerability in Microsoft 365 that could be exploited to infer message contents due to the use of a broken cryptographic algorithm. Office 365 Message Encryption is a security mechanism used to send and receive encrypted email messages between users inside and outside an organization without revealing anything about the communications themselves.
Details have emerged about a now-patched security flaw in Windows Common Log File System that could be exploited by an attacker to gain elevated permissions on compromised machines. "The cause of the vulnerability is due to the lack of a strict bounds check on the field cbSymbolZone in the Base Record Header for the base log file in CLFS.sys," the cybersecurity firm said in a root cause analysis shared with The Hacker News.
Ai researchers have released a PoC exploit for CVE-2022-40684, the authentication bypass vulnerability affecting Fortinet's firewalls and secure web gateways, and soon after exploitation attempts started rising. " , the Wordfence Threat Intelligence team began tracking exploit attempts targeting CVE-2022-40684 on our network of over 4 million protected websites," Wordfence threat analyst Ram Gall shared.
A threat actor tracked as Polonium has been linked to over a dozen highly targeted attacks aimed at Israelian entities with seven different custom backdoors since at least September 2021. ESET's latest discovery of five more previously undocumented backdoors brings into focus an active espionage-oriented threat actor that's constantly refining and retooling its malware arsenal.
A now-patched security flaw in the vm2 JavaScript sandbox module could be abused by a remote adversary to break out of security barriers and perform arbitrary operations on the underlying machine. "A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox," GitHub said in an advisory published on September 28, 2022.
"This platform has an intuitive interface and comes at a relatively low cost while providing a multitude of features and tools to its criminal clients to orchestrate and automate core elements of their phishing campaigns," Mandiant said in a new report. Some of the core features offered by the platform comprise the ability to craft customized phishing kits, manage redirect pages, dynamically generate URLs that host the payloads, and track the success of the campaigns.
A new piece of research has detailed the increasingly sophisticated nature of the malware toolset employed by an advanced persistent threat group named Earth Aughisky. "Over the last decade, the group has continued to make adjustments in the tools and malware deployments on specific targets located in Taiwan and, more recently, Japan," Trend Micro disclosed in a technical profile last week.
