Ivanti, the company behind Pulse Secure VPN appliances, has released a security patch to remediate a critical security vulnerability that was found being actively exploited in the wild by at least two different threat actors. Tracked as  CVE-2021-22893  (CVSS score 10), the flaw concerns "multiple use after free" issues in Pulse Connect Secure that could allow a remote unauthenticated attacker to execute arbitrary code and take control of the affected system. All Pulse Connect Secure versions prior to 9.1R11.4 are impacted. The flaw came to light on April 20 after FireEye  disclosed  a series of intrusions targeting defense, government, and financial organizations in the U.S. and elsewhere by leveraging critical vulnerabilities in the remote access solution to bypass multi-factor authentication protections and breach enterprise networks. The development promoted the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to issue an  Emergency Directive  urging fede

Apple on Monday released security updates for  iOS ,  macOS , and  watchOS  to address three zero-day flaws and expand patches for a fourth vulnerability that the company said might have been exploited in the wild. The weaknesses all concern WebKit, the browser engine which powers Safari and other third-party web browsers in iOS, allowing an adversary to execute arbitrary code on target devices. A summary of the three security bugs are as follows - CVE-2021-30663:  An integer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved input validation. CVE-2021-30665:  A memory corruption issue that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addressed with improved state management. CVE-2021-30666:  A buffer overflow vulnerability that could be exploited to craft malicious web content, which may lead to code execution. The flaw was addr

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

Most mobile app users tend to blindly trust that the apps they download from app stores are safe and secure. But that isn't always the case. To demonstrate the pitfalls and identify vulnerabilities on a large scale, cybersecurity and machine intelligence company CloudSEK recently provided a platform called  BeVigil  where individuals can search and check app security ratings and other security issues before installing an app. A latest  report  shared with The Hacker News detailed how the BeVigil search engine identified over 40 apps - with more than a cumulative 100 million downloads - that had hardcoded private Amazon Web Services (AWS) keys embedded within them, putting their internal networks and their users' data at risk of cyberattacks. BeVigil finds popular apps leaking AWS keys The AWS key leakage was spotted in some of the major apps such as Adobe Photoshop Fix, Adobe Comp, Hootsuite, IBM's Weather Channel, and online shopping services Club Factory and Wholee.

Cybersecurity researchers on Monday disclosed a new malspam campaign distributing a fresh variant of a malware loader called "Buer" written in Rust, illustrating how adversaries are constantly honing their malware toolsets to evade analysis. Dubbed "RustyBuer," the malware is propagated via emails masquerading as shipping notices from DHL Support, and is said to have affected no fewer than 200 organizations across more than 50 verticals since early April. "The new Buer variant is written in Rust, an efficient and easy-to-use programming language that is becoming increasingly popular," Proofpoint researchers  said  in a report shared with The Hacker News. "Rewriting the malware in Rust enables the threat actor to better evade existing Buer detection capabilities." First introduced in August of 2019,  Buer  is a modular malware-as-a-service offering that's sold on underground forums and used as a first-stage downloader to deliver additiona

Iran has been linked to yet another state-sponsored ransomware operation through a contracting company based in the country, according to new analysis. "Iran's Islamic Revolutionary Guard Corps ( IRGC ) was operating a state-sponsored ransomware campaign through an Iranian contracting company called 'Emen Net Pasargard' (ENP)," cybersecurity firm Flashpoint  said  in its findings summarizing three documents leaked by an anonymous entity named Read My Lips or Lab Dookhtegan between March 19 and April 1 via its Telegram channel. Dubbed "Project Signal," the initiative is said to have kickstarted sometime between late July 2020 and early September 2020, with ENP's internal research organization, named the "Studies Center," putting together a list of unspecified target websites. A second spreadsheet validated by Flashpoint explicitly spelled out the project's financial motivations, with plans to launch the ransomware operations in late

A threat actor believed to be working on behalf of Chinese state-sponsored interests was recently observed targeting a Russia-based defense contractor involved in designing nuclear submarines for the naval arm of the Russian Armed Forces. The phishing attack, which singled out a general director working at the Rubin Design Bureau, leveraged the infamous "Royal Road" Rich Text Format (RTF) weaponizer to deliver a previously undocumented Windows backdoor dubbed " PortDoor ," according to Cybereason's Nocturnus threat intelligence team. "Portdoor has multiple functionalities, including the ability to do reconnaissance, target profiling, delivery of additional payloads, privilege escalation, process manipulation static detection antivirus evasion, one-byte XOR encryption, AES-encrypted data exfiltration and more," the researchers  said  in a write-up on Friday. Rubin Design Bureau is a submarine design center located in Saint Petersburg, accounting fo

An "aggressive" financially motivated threat group tapped into a zero-day flaw in SonicWall VPN appliances prior to it being patched by the company to deploy a new strain of ransomware called FIVEHANDS. The group, tracked by cybersecurity firm Mandiant as UNC2447, took advantage of an "improper SQL command neutralization" flaw in the SSL-VPN SMA100 product ( CVE-2021-20016 , CVSS score 9.8) that allows an unauthenticated attacker to achieve remote code execution. "UNC2447 monetizes intrusions by extorting their victims first with FIVEHANDS ransomware followed by aggressively applying pressure through threats of media attention and offering victim data for sale on hacker forums," Mandiant researchers  said . "UNC2447 has been observed targeting organizations in Europe and North America and has consistently displayed advanced capabilities to evade detection and minimize post-intrusion forensics." CVE-2021-20016 is the same  zero-day  that the

Microsoft researchers on Thursday disclosed two dozen vulnerabilities affecting a wide range of Internet of Things (IoT) and Operational Technology (OT) devices used in industrial, medical, and enterprise networks that could be abused by adversaries to execute arbitrary code and even cause critical systems to crash. "These remote code execution (RCE) vulnerabilities cover more than 25 CVEs and potentially affect a wide range of domains, from consumer and medical IoT to Industrial IoT, Operational Technology, and industrial control systems,"  said  Microsoft's 'Section 52' Azure Defender for IoT research group. The flaws have been collectively named " BadAlloc ," for they are rooted in standard  memory allocation functions  spanning widely used real-time operating systems (RTOS), embedded software development kits (SDKs), and C standard library (libc) implementations. A lack of proper input validations associated with these memory allocation functions

Perhaps due to the nature of the position, the InfoSec leadership roles tend to be solitary ones. CISOs, or their equivalent decision-makers in organizations without the role, have so many constant drains on their attention – keeping their knowledge fresh, building plans to secure their organizations further – that they often find themselves on an island. It's even more challenging for organizations outside the Fortune 2000 that are resource-constrained. Security leaders are expected to know everything and often don't have anyone inside their organization with whom to bounce ideas or even go to for advice. When a crisis arises, they must often go with their gut or guess at the best solution based on their own experiences. Security leaders could often use advice but don't have an outlet for it. Chris Roberts, Chief Security Strategist at Cynet Security, offers a new Slack-based community for InfoSec leaders ( register here ) as a solution. The new InfoSec Leaders Community will fea
