The Iranian nation-state group known as  MuddyWater  has been observed carrying out destructive attacks on hybrid environments under the guise of a ransomware operation. That's according to new findings from the Microsoft Threat Intelligence team, which discovered the threat actor targeting both on-premises and cloud infrastructures in partnership with another emerging activity cluster dubbed  DEV-1084 . "While the threat actors attempted to masquerade the activity as a standard ransomware campaign, the unrecoverable actions show destruction and disruption were the ultimate goals of the operation," the tech giant  revealed  Friday. MuddyWater  is the name assigned to an  Iran-based actor  that the U.S. government has publicly connected to the country's Ministry of Intelligence and Security (MOIS). It's been known to be active since at least 2017. It's also tracked by the cybersecurity community under various names, including Boggy Serpens, Co...

Apple on Friday released security updates for  iOS, iPadOS ,  macOS , and  Safari web browser  to address a pair of zero-day flaws that are being exploited in the wild. The two vulnerabilities are as follows - CVE-2023-28205  - A  use after free issue  in WebKit that could lead to arbitrary code execution when processing specially crafted web content. CVE-2023-28206  - An  out-of-bounds write issue  in IOSurfaceAccelerator that could enable an app to execute arbitrary code with kernel privileges. Apple said it addressed CVE-2023-28205 with improved memory management and the second with better input validation, adding it's aware the bugs "may have been actively exploited." Credited with discovering and reporting the flaws are Clément Lecigne of Google's Threat Analysis Group (TAG) and Donncha Ó Cearbhaill of Amnesty International's Security Lab. Details about the two vulnerabilities have been withheld in light of active exploi...

The stakes are high when it comes to cybersecurity. No longer are we dealing with unskilled hackers trying to break into corporate systems with brute force. Today, cybercriminals are using highly sophisticated methods like social engineering, spear phishing, and BEC to target users directly and log in with valid credentials. This is why the identity perimeter has become a critical battleground in the fight against cyberattacks. But, many businesses are still relying on outdated security strategies and tools, leaving their users and sensitive systems exposed. To help you tackle this pressing issue, we're inviting you to join our upcoming webinar with Dor Dali, Head of Research at Cyolo. Dor has extensive experience in the field and will be sharing his insights on how to secure your identity perimeter and overcome common challenges. Here's what you can expect from the webinar: A deep dive into what the identity perimeter is and why it should be a critical focus point of y...

The maintainers of the vm2 JavaScript sandbox module have shipped a patch to address a critical flaw that could be abused to break out of security boundaries and execute arbitrary shellcode. The flaw, which affects all versions, including and prior to 3.9.14, was  reported  by researchers from South Korea-based  KAIST WSP Lab  on April 6, 2023, prompting vm2 to release a fix with  version 3.9.15  on Friday. "A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox," vm2  disclosed  in an advisory. The vulnerability has been assigned the identified  CVE-2023-29017  and is rated 9.8 on the CVSS scoring system. The issue stems from the fact that it does not properly handle errors that occur in asynchronous functions. vm2 is a  popular library  that's used to run untrusted code in an isolated environment on Node.js. It has nearly four million weekly downloads and i...

In yet another sign that Telegram is increasingly becoming a  thriving hub  for cybercrime, researchers have found that threat actors are using the messaging platform to peddle phishing kits and help set up phishing campaigns. "To promote their 'goods,' phishers create Telegram channels through which they educate their audience about phishing and entertain subscribers with polls like, 'What type of personal data do you prefer?'," Kaspersky web content analyst Olga Svistunova  said  in a report published this week. The links to these Telegram channels are distributed via YouTube, GitHub, and the phishing kits that are developed by the crooks themselves. The Russian cybersecurity firm said it detected over 2.5 million malicious URLs generated using phishing kits in the past six months. One of the prominent services offered is to provide threat actors with Telegram bots that automate the process of generating phishing pages and collecting user data. Although...

Microsoft said it teamed up with Fortra and Health Information Sharing and Analysis Center (Health-ISAC) to tackle the abuse of Cobalt Strike by cybercriminals to distribute malware, including ransomware. To that end, the tech giant's Digital Crimes Unit (DCU) revealed that it secured a  court order  in the U.S. to "remove illegal, legacy copies of Cobalt Strike so they can no longer be used by cybercriminals." While Cobalt Strike, developed and maintained by Fortra (formerly HelpSystems), is a legitimate post-exploitation tool used for adversary simulation, illegal cracked versions of the software have been weaponized by threat actors over the years. Ransomware groups, in particular, have leveraged Cobalt Strike after obtaining initial access to a target environment to escalate privileges, lateral move across the network, and deploy file-encrypting malware. "The ransomware families associated with or deployed by cracked copies of Cobalt Strike have been link...

Less than a month ago, Twitter indirectly acknowledged that some of its source code had been leaked on the code-sharing platform GitHub by sending a copyright infringement notice to take down the incriminated repository. The latter is now inaccessible, but according to the media, it was accessible to the public for several months. A user going by the name FreeSpeechEnthousiast committed thousands of documents belonging to the social media platform over several months.  While there is no concrete evidence to support this hypothesis, the timing of the leak and the ironic username used by the perpetrator suggest that the leak was a deliberate act aimed at causing harm to the company. Although it is still too early to measure the impact of this leak on the health of Twitter, this incident should be an opportunity for all software vendors to ask a simple question:  what if this happened to us? Protecting sensitive information in the software industry is becoming increasingly cr...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  published   eight  Industrial Control Systems (ICS) advisories warning of critical flaws affecting products from Hitachi Energy, mySCADA Technologies, Industrial Control Links, and Nexx. Topping the list is  CVE-2022-3682  (CVSS score: 9.9), impacting Hitachi Energy's MicroSCADA System Data Manager SDM600 that could allow an attacker to take remote control of the product. The flaw stems from an issue with file permission validation, thereby permitting an adversary to upload a specially crafted message to the system, leading to arbitrary code execution. Hitachi Energy has released SDM600 1.3.0.1339 to  mitigate  the issue for SDM600 versions prior to version 1.2 FP3 HF4 (Build Nr. 1.2.23000.291). Another set of five critical vulnerabilities –  CVE-2023-28400 ,  CVE-2023-28716 ,  CVE-2023-28384 ,  CVE-2023-29169 , and  CVE-2023-29150  (CVSS scores: 9...

Critical infrastructure attacks are a preferred target for cyber criminals. Here's why and what's being done to protect them. What is Critical Infrastructure and Why is It Attacked? Critical infrastructure is the physical and digital assets, systems and networks that are vital to national security, the economy, public health, or safety. It can be government- or privately-owned. According to Etay Maor, Senior Director Security Strategy at  Cato Networks , "It's interesting to note critical infrastructure doesn't necessarily have to be power plants or electricity. A nation's monetary system or even a global monetary system can be and should be considered a critical infrastructure as well." These qualities make critical infrastructure a preferred target for cyber attacks. If critical infrastructure is disrupted, the impact is significant. In some cases, such cyber attacks on critical infrastructure have become another means of modern warfare. But unlike ...
