Recently Yahoo disclosed a three-year-old massive data breach in its company that exposed personal details associated with more than 1 Billion user accounts , which is said to be the largest data breach of any company ever. The new development in Yahoo!'s 2013 data breach is that the hacker sold its over Billion-user database on the Dark Web last August for $300,000, according to Andrew Komarov, Chief Intelligence Officer (CIO) at security firm InfoArmor. Komarov told the New York Times that three different buyers, including two "prominent spammers" and the third, is believed to be involved in espionage tactics paid $300,000 to gain control of the entire database. The hacker group that breached Yahoo and sold the database is believed to based in Eastern Europe, but the company still does not know if this information is accurate or not. Beside full names, passwords, date of births and phone numbers of 1 Million Yahoo users, the database also includes backup em...

No software is immune to being Hacked! Not even Linux. A security researcher has discovered a critical vulnerability in Ubuntu Linux operating system that would allow an attacker to remotely compromise a target computer using a malicious file. The vulnerability affects all default Ubuntu Linux installations versions 12.10 (Quantal) and later. Researcher Donncha O'Cearbhaill discovered the security bug which actually resides in the Apport crash reporting tool on Ubuntu. A successful exploit of this CrashDB code injection issue could allow an attacker to remotely execute arbitrary code on victim's machine. All an attacker needs is to trick the Ubuntu user into opening a maliciously booby-trapped crash file. This would inject malicious code in Ubuntu OS's crash file handler, which when parsed, executes arbitrary Python code. "The code first checks if the CrashDB field starts with { indicating the start of a Python dictionary," O'Cearbhaill explain...

Macintosh computers are often considered to be safer than those running Windows operating system, but a recently discovered attack technique proves it all wrong. All an attacker needs is a $300 device to seize full control of your Mac or MacBook. Swedish hacker and penetration tester Ulf Frisk has developed a new device that can steal the password from virtually any Mac laptop while it is sleeping or even locked in just 30 seconds, allowing hackers to unlock any Mac computer and even decrypt the files on its hard drive. So, next time when you leave your Apple's laptop unattended, be sure to shut it down completely rather than just putting the system in sleep mode or locked. Here's How an Attacker can steal your Mac FileVault2 Password The researcher devised this technique by exploiting two designing flaws he discovered last July in Apple's FileVault2 full-disk encryption software. The first issue is that the Mac system does not protect itself against Direc...

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...

One of the FBI's most wanted hackers who was behind the largest theft of financial data has finally been arrested at the JFK airport in New York. Joshua Samuel Aaron is accused of being part of a hacking group that attacked several major financial institutions, including JPMorgan Chase , and according to the officials, which was "the largest theft of user data from a U.S. financial institution in history." Aaron was believed to have been living as a fugitive in Moscow, Russia after being charged with hacking crimes in 2015, which exposed the personal information of more than 100 Million people. On June 2015, a federal arrest warrant was issued for Aaron by the United States District Court, and the FBI and US secret service agents arrested him upon his arrival at the JFK airport in NY, announced the US Department of Justice. "Aaron allegedly worked to hack into the networks of dozens of American companies, ultimately leading to the largest theft of person...

Remember The Shadow Brokers? The hacker group that's believed to be behind the high-profile cyber theft of NSA hacking tools and exploits that sparked a larger debate on the Internet concerning abilities of US intelligence agencies and their own security The group put the stolen cyber weapons on auction but received not much response and gone quiet for some time. However, The Shadow Brokers has now appeared to have put up the NSA's hacking tools and exploits for direct sale on an underground website. A newly uncovered site reportedly contains a file signed with the cryptographic key of The Shadow Brokers, suggesting the hacker group has now moved to sell NSA hacking tools directly to buyers one by one, Motherboard reports . On Wednesday, someone going by pseudonym Boceffus Cleetus published a post on Medium, saying that the Shadow Brokers hackers are now selling "NSA tools individually." "The site also lets visitors download a selection of scree...

Ashley Madison, an American most prominent dating website that helps married people cheat on their spouses has been hacked, has agreed to pay a hefty fine of $1.6 Million for failing to protect account information of 36 Million users , after a massive data breach last year. Yes, the parent company of Ashley Madison , Ruby Corp. will pay $1.6 Million to settle charges from both Federal Trade Commission (FTC) and 13 states alleging that it misled its consumers about its privacy practices and did not do enough to protect their information. Not only the company failed to protect the account information of its 36 Million users, but also it failed to delete account information after regretful users paid a $20 fee for "Full Delete" of their accounts. Moreover, the Ashley Madison site operators were accused of creating fake accounts of "female" users in an effort to attract new members. Avid Life Media denied the claim at the time, but a year later when the com...

In what believe to be the largest data breach in history, Yahoo is reporting a massive data breach that disclosed personal details associated with more than 1 Billion user accounts in August 2013. …And it's separate from the one disclosed by Yahoo! in September, in which hackers compromised as many as 500 Million user accounts in late 2014. What's troubling is that the company has not been able to discovered how "an unauthorized third party" were able to steal the data associated with more than one Billion users. The data breach officially disclosed on Wednesday actually occurred in 2013 and, just like the one in 2014, allowed the cyber crooks to obtain personal information of its users but not credit card details. Here's what Yahoo's chief information security officer Bob Lord says the hackers obtained: "The stolen user account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (using...

A security researcher has discovered a critical vulnerability in Facebook Messenger that could allow an attacker to read all your private conversation, affecting the privacy of around 1 Billion Messenger users. Ysrael Gurt, the security researcher at BugSec and Cynet, reported a cross-origin bypass-attack against Facebook Messenger which allows an attacker to access your private messages, photos as well as attachments sent on the Facebook chat. To exploit this vulnerability, all an attacker need is to trick a victim into visiting a malicious website; that's all. Once clicked, all private conversations by the victim, whether from a Facebook's mobile app or a web browser, would be accessible to the attacker, because the flaw affected both the web chat as well as the mobile application. Dubbed " Originull ," the vulnerability actually lies in the fact that Facebook chats are managed from a server located at {number}-edge-chat.facebook.com, which is separate from...

Those innocent-looking apps in your smartphone can secretly spy on your communications or could allow hackers to do so. Hard to believe, but it's true. Recently, Trustwave's SpiderLabs analysts discovered a hidden backdoor in Skype for Apple's macOS and Mac OS X operating systems that could be used to spy on users' communications without their knowledge. The backdoor actually resides in the desktop Application Programming Interface (API) that allows third-party plugins and apps to communicate with Microsoft-owned Skype — the popular video chat and messaging service. Appeared to have been around since at least 2010, the backdoor could allow any malicious third-party app to bypass authentication procedure and provide nearly complete access to Skype on Mac OS X. How an Attacker can Take Complete Control of Your Skype The malicious app could bypass authentication process if they "identified themselves as the program responsible for interfacing with th...

For the last Patch Tuesday for this year, Microsoft has released 12 security bulletins, half of which are rated 'critical' as they give attackers remote code execution capabilities on the affected computers. The security bulletins address vulnerabilities in Microsoft's Windows, Office, Internet Explorer and Edge. The first critical security bulletin, MS16-144 , patches a total of 8 security vulnerabilities in Internet Explorer, 3 of which had publicly been disclosed before Microsoft issued patches for them, though the company said they're not being exploited in the wild.

The remaining 5 security flaws include a scripting engine memory corruption b...

Here's some bad news for Android users again. Certain low-cost Android smartphones and tablets are shipped with malicious firmware, which covertly gathers data about the infected devices, displays advertisements on top of running applications and downloads unwanted APK files on the victim's devices. Security researchers from Russian antivirus vendor Dr.Web have discovered two types of downloader Trojans that have been incorporated in the firmware of a large number of popular Android devices operating on the MediaTek platform, which are mostly marketed in Russia. The Trojans, detected as Android.DownLoader.473.origin and Android.Sprovider.7 , are capable of collecting data about the infected devices, contacting their command-and-control servers, automatically updating themselves, covertly downloading and installing other apps based on the instructions it receives from their server, and running each time the device is restarted or turned on. The list of Android devic...

Since its launch over a month ago, new virtual currency Zcash (ZEC) has become a significant way for cybercrooks to make money by infecting computers with software mining program. Launched in late October, Zcash (ZEC) is a new cryptocurrency currency that claims to be more anonymous than Bitcoin, as the sender, recipient and value of transactions can be hidden. With this premise, Zcash attracted significant interest from academics, investors, miners, and cyber criminals. Within the first few hours of its launch, 1 ZEC reached $30,000, a relatively high value any cryptocurrency ever had. At the time of writing, 1 ZEC is worth 0.06 BTC or around $49. However, according to a blog post published on Monday by Kaspersky Lab, cyber criminals have already started deploying malware that installs on and infects the computers of unsuspecting users and then uses their resources to mine Zcash for the hacker's profit. You Might have Zcash Mining Malware on Your PC! The actual s...
