Critical Flaw in OpenSea Could Have Let Hackers Steal Cryptocurrency From Wallets

Critical Flaw in OpenSea Could Have Let Hackers Steal Cryptocurrency From Wallets

October 13, 2021Ravie Lakshmanan
A now-patched critical vulnerability in OpenSea, the world's largest non-fungible token ( NFT ) marketplace, could've been abused by malicious actors to drain cryptocurrency funds from a victim by sending a specially-crafted token, opening a new attack vector for exploitation. The findings come from cybersecurity firm Check Point Research, which began an investigation into the platform following public reports of stolen cryptocurrency wallets triggered by free airdropped NFTs. The issues were fixed in less than one hour of responsible disclosure on September 26, 2021. "Left unpatched, the vulnerabilities could allow hackers to hijack user accounts and steal entire cryptocurrency wallets by crafting malicious NFTs," Check Point researchers  said . As the name indicates, NFTs are unique digital assets such as photos, videos, audio, and other items that can be sold and traded on the blockchain, using the technology as a certificate of authenticity to establish a ver

GitHub Revoked Insecure SSH Keys Generated by a Popular git Client

October 12, 2021Ravie Lakshmanan
Code hosting platform GitHub has  revoked  weak SSH authentication keys that were generated via the GitKraken git GUI client due to a vulnerability in a third-party library that increased the likelihood of duplicated SSH keys. As an added precautionary measure, the Microsoft-owned company also said it's building safeguards to prevent vulnerable versions of GitKraken from adding newly generated weak keys. The problematic dependency, called " keypair ," is an open-source SSH key generation library that allows users to create RSA keys for authentication-related purposes. It has been found to impact  GitKraken  versions 7.6.x, 7.7.x, and 8.0.0, released between May 12, 2021, and September 27, 2021. The flaw — tracked as CVE-2021-41117 (CVSS score: 8.7) — concerns a bug in the pseudo-random number generator used by the library, resulting in the creation of a weaker form of public SSH keys, which, owing to their low entropy — i.e., the measure of randomness — could boost
Code Execution Bug Affects Yamale Python Package — Used by Over 200 Projects

Code Execution Bug Affects Yamale Python Package — Used by Over 200 Projects

October 07, 2021Ravie Lakshmanan
A high-severity code injection vulnerability has been disclosed in 23andMe's Yamale, a schema and validator for YAML, that could be trivially exploited by adversaries to execute arbitrary Python code. The flaw, tracked as  CVE-2021-38305  (CVSS score: 7.8), involves manipulating the schema file provided as input to the tool to circumvent protections and achieve code execution. Particularly, the  issue  resides in the schema parsing function, which allows any input passed to be evaluated and executed, resulting in a scenario where a specially-crafted string within the schema can be abused for the injection of system commands. Yamale is a Python package that allows developers to validate YAML — a data serialization language often used for writing configuration files — from the command line. The package is used by at least  224 repositories  on GitHub.  "This gap allows attackers that can provide an input schema file to perform Python code injection that leads to code execut

Incentivizing Developers is the Key to Better Security Practices

September 30, 2021The Hacker News
Professional developers want to embrace DevSecOps and write secure code, but their organizations need to support this seachange if they want that effort to grow. The cyber threat landscape is becoming more complex by the day. Attackers are constantly scanning networks for vulnerable applications, programs, cloud instances, and the latest flavor of the month is APIs, widely considered an easy win thanks to their often lax security controls. They are so persistent that new apps can sometimes be compromised and exploited within hours of deployment. The Verizon 2021 Data Breach Investigations Report makes it very clear that the threats leveled against businesses and organizations  are more dangerous  today than at any other point in history. It's becoming very clear that the only way to truly fortify the software being created is to ensure that it's built on secure code. In other words, the best way to stop the threat actor invasion is to deny them a foothold into your applications in

Google Warns of a New Way Hackers Can Make Malware Undetectable on Windows

September 24, 2021Ravie Lakshmanan
Cybersecurity researchers have disclosed a novel technique adopted by a threat actor to deliberately evade detection with the help of malformed digital signatures of its malware payloads. "Attackers created malformed code signatures that are treated as valid by Windows but are not able to be decoded or checked by OpenSSL code — which is used in a number of security scanning products," Google Threat Analysis Group's Neel Mehta  said  in a write-up published on Thursday. The new mechanism was observed to be exploited by a notorious family of unwanted software known as  OpenSUpdater  that's used to download and install other suspicious programs on compromised systems. Most targets of the campaign are users located in the U.S. who are prone to downloading cracked versions of games and other grey-area software. The findings come from a set of OpenSUpdater  samples   uploaded  to VirusTotal at least since mid-August. While adversaries in the past have relied on illega

More than one terabyte of data containing 5.5 million files has been left exposed, leaking personal information of over 100,000 customers of a Colombian real estate firm, according to cybersecurity company WizCase. The breach was discovered by Ata Hakçıl and his team in a database owned by Coninsa Ramon H, a company that specializes in architecture, engineering, construction, and real estate services. "There was no need for a password or login credentials to see this information, and the data was not encrypted," the researchers  said  in an exclusive report shared with The Hacker News. The data exposure is the result of a misconfigured Amazon Web Services (AWS) Simple Storage Service (S3) bucket, causing sensitive information such as clients' names, photos, and addresses to be disclosed. The details stored in the bucket range from invoices and income documents to quotes and account statements dating between 2014 and 2021. The complete list of information contained in
The Gap in Your Zero Trust Implementation

The Gap in Your Zero Trust Implementation

September 21, 2021The Hacker News
Over the last several years, there have been numerous high-profile security breaches. These breaches have underscored the fact that traditional cyber defenses have become woefully inadequate and that stronger defenses are needed. As such, many organizations have transitioned toward a zero trust security model. A zero trust security model is based on the idea that no IT resource should be trusted implicitly. Prior to the introduction of zero trust security, a user who authenticated into a network was trustworthy for the duration of their session, as was the user's device. In a zero trust model, a user is no longer considered to be trustworthy just because they entered a password at the beginning of their session. Instead, the user's identity is verified through multi-factor authentication, and the user may be prompted to re-authenticate if they attempt to access resources that are particularly sensitive or if the user attempts to do something out of the ordinary.

Unpatched High-Severity Vulnerability Affects Apple macOS Computers

September 21, 2021Ravie Lakshmanan
Cybersecurity researchers on Tuesday disclosed details of an unpatched zero-day vulnerability in macOS Finder that could be abused by remote adversaries to trick users into running arbitrary commands on the machines. "A vulnerability in macOS Finder allows files whose extension is inetloc to execute arbitrary commands, these files can be embedded inside emails which if the user clicks on them will execute the commands embedded inside them without providing a prompt or warning to the user," SSD Secure Disclosure  said  in a write-up published today. Park Minchan, an independent security researcher, has been credited with reporting the vulnerability which affects macOS versions of Big Sur and prior. The weakness arises due to the manner macOS processes INETLOC files — shortcuts to open internet locations such as RSS feeds, Telnet connections, or other online resources and local files — resulting in a scenario that allows commands embedded in those files to be executed wit

Cring Ransomware Gang Exploits 11-Year-Old ColdFusion Bug

September 21, 2021Ravie Lakshmanan
Unidentified threat actors breached a server running an unpatched, 11-year-old version of Adobe's ColdFusion 9 software in minutes to remotely take over control and deploy file-encrypting Cring ransomware on the target's network 79 hours after the hack. The server, which belonged to an unnamed services company, was used to collect timesheet and accounting data for payroll as well as to host a number of virtual machines, according to a report published by Sophos and shared with The Hacker News. The attacks originated from an internet address assigned to the Ukrainian ISP Green Floid. "Devices running vulnerable, outdated software are low-hanging-fruit for cyberattackers looking for an easy way into a target," Sophos principal researcher Andrew Brandt  said . "The surprising thing is that this server was in active daily use. Often the most vulnerable devices are inactive or ghost machines, either forgotten about or overlooked when it comes to patching and upgra

The U.S. Department of Justice (DoJ) on Tuesday disclosed it fined three intelligence community and military personnel $1.68 million in penalties for their role as cyber-mercenaries working on behalf of a U.A.E.-based cybersecurity company. The trio in question — Marc Baier, 49, Ryan Adams, 34, and Daniel Gericke, 40 — are accused of "knowingly and willfully combine, conspire, confederate, and agree with each other to commit offenses, "furnishing defense services to persons and entities in the country over a three year period beginning around December 2015 and continuing through November 2019, including developing invasive spyware capable of breaking into mobile devices without any action by the targets. "The defendants worked as senior managers at a United Arab Emirates (U.A.E.)-based company (U.A.E. CO) that supported and carried out computer network exploitation (CNE) operations (i.e., 'hacking') for the benefit of the U.A.E. government," the DoJ  said

Fighting the Rogue Toaster Army: Why Secure Coding in Embedded Systems is Our Defensive Edge

September 09, 2021The Hacker News
There are plenty of pop culture references to rogue AI and robots, and appliances turning on their human masters. It is the stuff of science fiction, fun, and fantasy, but with IoT and connected devices becoming more prevalent in our homes, we need more discussion around cybersecurity and safety. Software is all around us, and it's very easy to forget just how much we're relying on lines of code to do all those clever things that provide us so much innovation and convenience. Much like web-based software, APIs, and mobile devices, vulnerable code in embedded systems can be exploited if it is uncovered by an attacker.  While it's unlikely that an army of toasters is coming to enslave the human race (although, the  Tesla bot  is a bit concerning) as the result of a cyberattack, malicious cyber events are still possible. Some of our cars, planes, and medical devices also rely on intricate embedded systems code to perform key tasks, and the prospect of these objects being compromised i
