Cybersecurity researchers have documented a novel post-exploit persistence technique on iOS 16 that could be abused to fly under the radar and maintain access to an Apple device even when the victim believes it is offline. The method "tricks the victim into thinking their device's Airplane Mode works when in reality the attacker (following successful device exploit) has planted an artificial Airplane Mode which edits the UI to display Airplane Mode icon and cuts internet connection to all apps except the attacker application," Jamf Threat Labs researchers Hu Ke and Nir Avraham said in a report shared with The Hacker News. Airplane Mode , as the name implies, allows users to turn off wireless features in their devices, effectively preventing them from connecting to Wi-Fi networks, cellular data, and Bluetooth as well as sending or receiving calls and text messages. The approach devised by Jamf, in a nutshell, provides an illusion to the user that the Airplane Mode is...

A new, financially motivated operation dubbed  LABRAT  has been observed weaponizing a now-patched critical flaw in GitLab as part of a cryptojacking and proxyjacking campaign. "The attacker utilized undetected signature-based tools, sophisticated and stealthy cross-platform malware, command-and-control (C2) tools which bypassed firewalls, and kernel-based rootkits to hide their presence," Sysdig  said  in a report shared with The Hacker News. "Furthermore, the attacker abused a legitimate service,  TryCloudflare , to obfuscate their C2 network." Proxyjacking  allows the attacker to rent the compromised host out to a proxy network, making it possible to monetize the unused bandwidth. Cryptojacking, on the other hand, refers to the abuse of the system resources to mine cryptocurrency. A notable aspect of the campaign is the use of compiled binaries written in Go and .NET to fly under the radar, with LABRAT also providing backdoor access to the infected ...

Changes in the way we work have had significant implications for cybersecurity, not least in network monitoring. Workers no longer sit safely side-by-side on a corporate network, dev teams constantly spin up and tear down systems, exposing services to the internet. Keeping track of these users, changes and services is difficult – internet-facing attack surfaces rarely stay the same for long. But a secure working network is the backbone of every modern business, and with so many different attack vectors and entry points, relying on firewalls and point-in-time scanning is no longer enough. You need to understand how your firewalls are being changed in real-time, with real-world validation of how they're configured. You need continuous network monitoring. What needs protecting in your network? There is so much sprawl in today's corporate networks with remote working, cloud computing and third-party integrations, that it's no longer just the devices or systems that you have in your off...

An ongoing campaign targeting ministries of foreign affairs of NATO-aligned countries points to the involvement of Russian threat actors. The phishing attacks feature PDF documents with diplomatic lures, some of which are disguised as coming from Germany, to deliver a variant of a malware called  Duke , which has been attributed to  APT29  (aka BlueBravo, Cloaked Ursa, Cozy Bear, Iron Hemlock, Midnight Blizzard, and The Dukes). "The threat actor used Zulip – an open-source chat application – for command-and-control, to evade and hide its activities behind legitimate web traffic," Dutch cybersecurity company EclecticIQ  said  in an analysis last week. The infection sequence is as follows: The PDF attachment, named "Farewell to Ambassador of Germany," comes embedded with JavaScript code that initiates a multi-stage process to leave a persistent backdoor on compromised networks. APT29's use of invitation themes has been previously reported by Lab52, which...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security flaw in Citrix ShareFile storage zones controller to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active in-the-wild exploitation. Tracked as  CVE-2023-24489  (CVSS score: 9.8), the shortcoming has been described as an improper access control bug that, if successfully exploited, could allow an unauthenticated attacker to compromise vulnerable instances remotely. The problem is rooted in ShareFile's handling of cryptographic operations, enabling adversaries to upload arbitrary files, resulting in remote code execution. "This vulnerability affects all currently supported versions of customer-managed ShareFile storage zones controller before version 5.11.24," Citrix  said  in an advisory released in June. Dylan Pindur of Assetnote has been credited with discovering and reporting the issue. It's worth noting that the  first signs of explo...

At a little overt halfway through 2023, credential theft is still a major thorn in the side of IT teams. The heart of the problem is the value of data to cybercriminals and the evolution of the techniques they use to get hold of it. The  2023 Verizon Data Breach Investigations Report (DBIR)  revealed that 83% of breaches involved external actors, with almost all attacks being financially motivated. Of these breaches by external actors, 49% involved the use of stolen credentials.  We'll explore why credential theft is still such an attractive (and successful) attack route, and look at how IT security teams can fight back in the second half of 2023 and beyond. Users are still often the weak link The hallmarks of many successful cyberattacks are the determination, inventiveness, and patience threat actors show. Though a user may spot some attacks through security and awareness training, it only takes one well-crafted attack to catch them. Sometimes all it takes is for a ...

Active flaws in the PowerShell Gallery could be weaponized by threat actors to pull off supply chain attacks against the registry's users. "These flaws make typosquatting attacks inevitable in this registry, while also making it extremely difficult for users to identify the true owner of a package," Aqua security researchers Mor Weinberger, Yakir Kadkoda, and Ilay Goldman said in a report shared with The Hacker News. Maintained by Microsoft,  PowerShell Gallery  is a  central repository  for sharing and acquiring PowerShell code, including PowerShell modules, scripts, and Desired State Configuration (DSC) resources. The registry boasts of 11,829 unique packages and 244,615 packages in total. The issues identified by the cloud security firm have to do with the service's lax policy surrounding package names, lacking protections against typosquatting attacks, as a result enabling attackers to upload malicious PowerShell modules that appear genuine to unsuspecting u...
