Researchers from cybersecurity firm Proofpoint have recently discovered a large-scale malvertising campaign that exposed millions of Internet users in the United States, Canada, the UK, and Australia to malware infections. Active for more than a year and still ongoing, the malware campaign is being conducted by a hacking group called KovCoreG , which is well known for distributing Kovter ad fraud malware that was used in 2015 malicious ad campaign s, and most recently earlier in 2017 . The KovCoreG hacking group initially took advantage of P0rnHub—one of the world's most visited adult websites—to distribute fake browser updates that worked on all three major Windows web browsers, including Chrome, Firefox, and Microsoft Edge/Internet Explorer. According to the Proofpoint researchers, the infections in this campaign first appeared on P0rnHub web pages via a legitimate advertising network called Traffic Junky, which tricked users into installing the Kovtar malware onto the...

Another day, Another data breach disclosure. This time the popular commenting system has fallen victim to a massive security breach. Disqus, the company which provides a web-based comment plugin for websites and blogs, has admitted that it was breached 5 years ago in July 2012 and hackers stole details of more than 17.5 million users. The stolen data includes email addresses, usernames, sign-up dates, and last login dates in plain text for all 17.5 million users. What's more? Hackers also got their hands on passwords for about one-third of the affected users, which were salted and hashed using the weak SHA-1 algorithm. The company said the exposed user information dates back to 2007 with the most recently exposed from July 2012. According to Disqus, the company became aware of the breach Thursday (5th October) evening after an independent security researcher Troy Hunt, who obtained a copy of the site's information, notified the company. Within about 24 hours, ...

While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

Do you know—United States Government has banned federal agencies from using Kaspersky antivirus software over spying fear? Though there's no solid evidence yet available, an article published by WSJ claims  that the Russian state-sponsored hackers stole highly classified NSA documents from a contractor in 2015 with the help of a security program made by Russia-based security firm Kaspersky Lab. Currently, there is no way to independently confirm if the claims on the popular security vendor published by the Wall Street Journal is accurate—and the story does not even prove the involvement of Kaspersky. "As a private company, Kaspersky Lab does not have inappropriate ties to any government, including Russia, and the only conclusion seems to be that Kaspersky Lab is caught in the middle of a geopolitical fight," Kaspersky said in a statement. The NSA contractor working with the American intelligence agency, whose identity has not yet been disclosed, reportedly do...

If you are an iPhone user and use Uber app, you would be surprised to know that widely popular ride-hailing app can record your screen secretly. Security researcher Will Strafach recently revealed that Apple selectively grants (what's known as an " entitlement ") Uber a powerful ability to use the newly introduced screen-recording API with intent to improve the performance of the Uber app on Apple Watch. The screen-recording API allows the Uber app to record user's screen information even when the app is closed, giving Uber access to all the personal information passing through an iPhone screen. What's more?  The company's access to such permission could make this data vulnerable to hackers if they, somehow, able to hijack Uber's software. "It looks like no other third-party developer has been able to get Apple to grant them a private sensitive entitlement of this nature," Strafach told Gizmodo , who first reported about the issue. ...

A severe programming error has been discovered in Apple's latest macOS High Sierra 10.13 that exposes passwords of encrypted Apple File System (APFS) volumes in plain text. Reported by Matheus Mariano, a Brazilian software developer, the vulnerability affects encrypted volumes using APFS wherein the password hint section is showing the actual password in the plain text. Yes, you got that right—your Mac mistakenly reveals the actual password instead of the password hint. In September, Apple released macOS High Sierra 10.13 with APFS (Apple File System) as the default file system for solid-state drives (SSDs) and other all-flash storage devices, promising strong encryption and better performance. Mariano discovered the security issue while he was using the Disk Utility in macOS High Sierra to add a new encrypted APFS volume to a container. When adding a new volume, he was asked to set a password and, optionally, write a hint for it. So, whenever the new volume is mounted, m...

It seems sophisticated hackers have changed the way they conduct targeted cyber operations—instead of investing in zero-days and developing their malware; some hacking groups have now started using ready-made malware just like script kiddies. Possibly, this could be a smart move for state-sponsored hackers to avoid being attributed easily. Security researchers from multiple security firms, including Arbor Networks and FireEye , independently discovered a series of malware campaigns primarily targeting aerospace, defence contractors and manufacturing sectors in various countries, including the United States, Thailand, South Korea and India. What's common? All these attack campaigns, conducted by various hacking groups, eventually install same information and password stealer malware—dubbed FormBook —on the targeted systems. FormBook is nothing but a " malware-as-as-service ," which is an affordable piece of data-stealing and form-grabbing malware that has been ...

A Greek court has approved the U.S. extradition of a 38-year-old Russian national accused of laundering more than $4 billion in bitcoin for culprits involved in hacking attacks, tax fraud and drug trafficking with the help of the now-defunct BTC-e exchange. Alexander Vinnik , an alleged operator of BTC-e—a digital currency exchange service that has been in operation since 2011 but seized by the authorities right after Vinnik's arrest in a beachside village in northern Greece in late July 2016 at the request of US law enforcement authorities. Since his arrest, Moscow has also requested Vinnik be returned home, as it has previously done with other Russian nationals wanted by the United States. However, the Greek court ruled Wednesday (4 October) to extradite Vinnik to the U.S., where he will face trial on the charges with the operation of an unlicensed money service business, money laundering, conspiracy to commit money laundering, and engaging in unlawful monetary transact...

The Apache Tomcat team has recently patched several security vulnerabilities in Apache Tomcat, one of which could allow an unauthorised attacker to execute malicious code on affected servers remotely. Apache Tomcat, developed by the Apache Software Foundation (ASF), is an open source web server and servlet system, which uses several Java EE specifications like Java Servlet, JavaServer Pages (JSP), Expression Language, and WebSocket, and provides a "pure Java" HTTP web server environment for Java concept to run in. Unlike Apache Struts2 vulnerabilities , which have recently been exploited to breach the systems of American credit reporting agency Equifax , Apache Tomcat flaws are less likely to be exploited. The critical Remote Code Execution (RCE) vulnerability (CVE-2017-12617) discovered in Apache Tomcat is due to insufficient validation of user-supplied input by the affected software. Only systems with HTTP PUTs enabled (via setting the "read-only" initi...

Spain's National Court ruled on Tuesday to extradite a 36-year-old Russian computer programmer, accused by American authorities of malicious hacking offences, to the United States, according to a court document. Peter Yuryevich Levashov , also known as Peter Severa, was arrested in April this year when he was travelling with his family to Barcelona, Spain from his home in Russia—a country without an extradition treaty with the United States—for his role in a huge computer botnet. However, since Levashov has previously worked with for Vladimir Putin's United Russia Party for ten years, he fears that the US authorities would torture him for information about his political work if sent there to face the charges against him. " If I go to the U.S., I will die in a year. They want to get information of a military nature and about the United Russia party ," RIA news agency quoted Levashov as saying. " I will be tortured, within a year I will be killed, or I wil...
