Instagram Bug Exposed Private Accounts, Allowing Unfettered Access to Archived Content

June 15, 2021

Instagram has resolved a significant vulnerability that permitted anyone to access archived posts and stories from private accounts without needing to follow them. Security researcher Mayur Fartade revealed in a Medium post today that “this bug could have allowed a malicious user to view targeted media on Instagram.” By leveraging the Media ID, an attacker could see details of private posts, stories, reels, and IGTV videos without following the user. Fartade reported the issue to Facebook’s security team on April 16, 2021, and the flaw was patched on June 15, leading to a $30,000 reward for his efforts through the company’s bug bounty program. Although exploiting this vulnerability required knowledge of the media ID, Fartade demonstrated that by brute-forcing the identifiers, it was feasible to send a POST request to a GraphQL endpoint and access sensitive information. As a result of this flaw, details like likes, comments, and saves could have been exposed.

“Understanding the Hacker’s Mindset: A Reflection on Their Essential Role in Cybersecurity”

On January 25, 2013, the critical role of hackers in cybersecurity became increasingly recognized. Often viewed as a nightmare by security experts, these specialists possess invaluable knowledge that sheds light on the vulnerabilities in our infrastructures. To effectively protect systems, one must adopt a hacker’s perspective.

Hacking embodies a culture and lifestyle that often clashes with conventional business logic. True hackers are not solely motivated by financial gain; while money is important, their primary drive lies in challenging their own skills and continuously pushing their limits.

Fortunately, the government and private sectors have come to appreciate the importance of hackers, transforming their reputation from undesirable outcasts to highly sought-after professionals. Identifying vulnerabilities before malicious actors can exploit them is crucial, especially in an era where millions of people and devices are interconnected.

Unpacking the Evolving Role of Hackers in Cybersecurity January 25, 2013 In today’s digital landscape, the role of hackers has taken on unprecedented significance, particularly within the realm of cybersecurity. Once perceived as antagonists by security professionals, hackers have emerged…

ShadowCaptcha Targets WordPress Sites to Distribute Ransomware, Info Stealers, and Crypto Miners

August 26, 2025
Ransomware / Cryptojacking

A significant new campaign has been uncovered, impacting over 100 compromised WordPress sites. This initiative redirects visitors to fake CAPTCHA verification pages employing the ClickFix social engineering technique to disseminate information stealers, ransomware, and cryptocurrency miners. Dubbed ShadowCaptcha by the Israel National Digital Agency, this widespread cybercrime operation, first detected in August 2025, utilizes a combination of social engineering, living-off-the-land binaries (LOLBins), and multi-stage payload delivery to establish and sustain access to targeted systems. Researchers Shimi Cohen, Adi Pick, Idan Beit Yosef, Hila David, and Yaniv Goldman explain, “The ultimate aims of ShadowCaptcha include harvesting sensitive information through credential theft and browser data exfiltration, deploying cryptocurrency miners for illicit gains, and even initiating ransomware outbreaks.” The attacks commence when unsuspecting users visit a compromised site…

Urgent: Update Your Chrome Browser to Address New 0-Day Vulnerability

June 18, 2021

Google has released an important update for the Chrome browser on Windows, Mac, and Linux to resolve four security vulnerabilities, including a critical zero-day flaw currently being exploited. This issue, identified as CVE-2021-30554, is a high-severity “use after free” vulnerability in WebGL (Web Graphics Library), which is a JavaScript API used for rendering interactive 2D and 3D graphics in the browser. Exploiting this flaw could lead to data corruption, crashes, and unauthorized execution of code or commands. Google received an anonymous report about the vulnerability on June 15, and Chrome technical program manager Srinivas Sista confirmed that the company is “aware that an exploit for CVE-2021-30554 exists in the wild.” While it’s standard practice to withhold specific details until most users have applied the fix, this announcement comes just days after Google addressed another zero-day vulnerability.

MixShell Malware Exploits Contact Forms to Target U.S. Supply Chain Manufacturers

Date: Aug 26, 2025
Categories: Enterprise Security / Artificial Intelligence

Cybersecurity experts are highlighting a complex social engineering initiative aimed at crucial supply chain manufacturing firms, deploying in-memory malware known as MixShell. This campaign, dubbed “ZipLine” by Check Point Research, circumvents traditional phishing tactics by initiating contact through companies’ public “Contact Us” forms. Attackers deceive employees into engaging in what appears to be a legitimate communication. According to Check Point’s statement to The Hacker News, these interactions can span several weeks, often involving fabricated non-disclosure agreements before the attackers deliver a weaponized ZIP file containing the stealthy MixShell malware. The attacks have impacted various organizations across multiple sectors, with a particular focus on U.S. manufacturers in industrial fields such as machinery, metalworking, component production, and engine manufacturing.

Bit9 Security Breach: Hackers Steal Digital Certificates to Sign Malware

February 9, 2013

Bit9 revealed on Friday that cybercriminals had compromised its network and stolen digital code-signing certificates, which were then used to sign malware. As a provider of software and network security solutions to the U.S. government and over 30 Fortune 100 companies, Bit9’s Chief Executive Patrick Morley outlined the situation in a blog post. “A malicious third party illegally gained temporary access to one of our digital code-signing certificates and used it to sign malware,” he stated. The signed malware was distributed to at least three of Bit9’s customers, although the company has not disclosed the identities of those affected or the extent of the damage. “Since identifying this issue, we have collaborated closely with our customers to ensure they are no longer vulnerable to malware associated with the compromised certificate,” the company confirmed, asserting that the issue has been resolved. This incident marks another instance of hackers targeting security firms.
