A global mobile espionage campaign collecting a trove of sensitive personal information from victims since at least 2012 has accidentally revealed itself—thanks to an exposed server on the open internet. It's one of the first known examples of a successful large-scale hacking operation of mobile phones rather than computers. The advanced persistent threat (APT) group, dubbed Dark Caracal , has claimed to have stolen hundreds of gigabytes of data, including personally identifiable information and intellectual property, from thousands of victims in more than 21 different countries, according to a new report from the Electronic Frontier Foundation (EFF) and security firm Lookout. After mistakenly leaking some of its files to the internet, the shadowy hacking group is traced back to a building owned by the Lebanese General Directorate of General Security (GDGS), one of the country's intelligence agencies, in Beirut. "Based on the available evidence, it's likely

If you came across any Facebook message with a video link sent by anyone, even your friend — just don't click on it. Security researchers at Kaspersky Lab have spotted an ongoing cross-platform campaign on Facebook Messenger, where users receive a video link that redirects them to a fake website, luring them to install malicious software. Although it is still unclear how the malware spreads, researchers believe spammers are using compromised accounts, hijacked browsers, or clickjacking techniques to spread the malicious link. The attackers make use of social engineering to trick users into clicking the video link, which purports to be from one of their Facebook friends, with the message that reads "< your friend name > Video" followed by a bit.ly link, as shown. Here's How this Cross-Platform Malware Works: The URL redirects victims to a Google doc that displays a dynamically generated video thumbnail, like a playable movie, based on the sender'

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

A few months back we reported how opening a simple MS Word file could compromise your computer using a critical vulnerability in Microsoft Office . The Microsoft Office remote code execution vulnerability (CVE-2017-0199) resided in the Windows Object Linking and Embedding (OLE) interface for which a patch was issued in April this year, but threat actors are still abusing the flaw through the different mediums. Security researchers have spotted a new malware campaign that is leveraging the same exploit, but for the first time, hidden behind a specially crafted PowerPoint (PPSX) Presentation file. According to the researchers at Trend Micro, who spotted the malware campaign, the targeted attack starts with a convincing spear-phishing email attachment, purportedly from a cable manufacturing provider and mainly targets companies involved in the electronics manufacturing industry. Researchers believe this attack involves the use of a sender address disguised as a legitimate ema

Last month, we reported about a group of hackers exploiting SambaCry —a 7-year-old critical remote code execution vulnerability in Samba networking software—to hack Linux computers and install malware to mine cryptocurrencies. The same group of hackers is now targeting Windows machines with a new backdoor, which is a QT-based re-compiled version of the same malware used to target Linux. Dubbed CowerSnail , detected by security researchers at Kaspersky Labs as Backdoor.Win32.CowerSnail, is a fully-featured windows backdoor that allows its creators to remotely execute any commands on the infected systems. Wondering how these two separate campaigns are connected? Interestingly, the CowerSnail backdoor uses the same command and control (C&C) server as the malware that was used to infect Linux machines to mine cryptocurrency last month by exploiting the then-recently exposed SambaCry vulnerability. Common C&C Server Location — cl.ezreal.space:20480 SambaCry vulnerabi

When the world was dealing with the threat of the self-spreading WannaCry ransomware , WikiLeaks released a new batch of CIA Vault 7 leaks , detailing two apparent CIA malware frameworks for the Microsoft Windows platform. Dubbed " AfterMidnight " and " Assassin ," both malware programs are designed to monitor and report back actions on the infected remote host computer running the Windows operating system and execute malicious actions specified by the CIA. Since March, WikiLeaks has published hundreds of thousands of documents and secret hacking tools that the group claims came from the US Central Intelligence Agency (CIA). This latest batch is the 8th release in the whistleblowing organization's 'Vault 7' series. 'AfterMidnight' Malware Framework According to a statement from WikiLeaks, 'AfterMidnight' allows its operators to dynamically load and execute malicious payload on a target system. The main controller of the ma

A Russian computer hacker arrested over the weekend in Barcelona was apparently detained for his role in a massive computer botnet, and not for last year's US presidential election hack as reported by the Russian media. Peter Yuryevich Levashov, 32-years-old Russian computer programmer, suspected of operating the Kelihos botnet — a global network of over 100,000 infected computers that was used to deliver spam, steal login passwords, and infect computers with ransomware and other types of malware since approximately 2010, the U.S. Justice Department announced Monday. As suspected earlier, Levashov, also known as Peter Severa, is the same man who has also been listed in the World's Top 10 Worst Spammers maintained by anti-spam group Spamhaus , which has given him the 7th position in the list. The arrest was made possible after the FBI learned just last month that Levashov was traveling with his family to Spain from his home in Russia, a country without any extraditi

As part of its Vault 7 series of leaked documents, whistleblowing website WikiLeaks today released a new cache of 27 documents allegedly belonged to the US Central Intelligence Agency (CIA). Named Grasshopper , the latest batch reveals a CLI-based framework developed by the CIA to build "customised malware" payloads for breaking into Microsoft's Windows operating systems and bypassing antivirus protection. All the leaked documents are basically a user manual that the agency flagged as "secret" and that are supposed to be only accessed by the members of the agency, WikiLeaks claims. Grasshopper: Customized Malware Builder Framework According to the leaked documents, Grasshopper framework allows the agency members to easily create custom malware, depending upon the technical details, such as what operating system and antivirus the targets are using. The Grasshopper framework then automatically puts together several components sufficient for attack

It is no secret that cybercriminals are becoming dramatically more adept, innovative, and stealthy with each passing day. While new forms of cybercrime are on the rise, traditional activities seem to be shifting towards more clandestine techniques that involve the exploitation of standard system tools and protocols, which are not always monitored. The latest example of such attack is DNSMessenger – a new Remote Access Trojan (RAT) that uses DNS queries to conduct malicious PowerShell commands on compromised computers – a technique that makes the RAT difficult to detect onto targeted systems. The Trojan came to the attention of Cisco's Talos threat research group by a security researcher named Simpo, who highlighted a tweet that encoded text in a PowerShell script that said 'SourceFireSux.' SourceFire is one of Cisco's corporate security products. DNSMessenger Attack Is Completely Fileless Further analysis of the malware ultimately led Talos researchers to

Till now we have seen a series of different malware targeting Windows operating system and not Mac, thanks to Apple in way it safeguard its devices' security. But with time, cyber criminals and malware authors have found ways to exploit Mac as well. GROUP BEHIND THE MAC VERSION OF BACKDOOR Researchers have unmasked a group of cyber criminals that has recently started using a new variant of XSLCmd backdoor program to target Mac OS X systems. This Mac version of backdoor shares a significant portion of its code with the Windows version of the same backdoor that has been around since at least 2009. According to FireEye researchers, the group, dubbed as GREF , is already infamous for its past cyber espionage attacks against the US Defense Industrial Base (DIB), companies from the electronics and engineering sectors worldwide, foundations and other NGO's as well. " We track this threat group as "GREF" due to their propensity to use a variety of Google references in th

Malware is nothing but a malicious files which is stored on an infected computer system in order to damage the system or steal sensitive data from it or perform other malicious activities. But security researchers have uncovered a new and sophisticated piece of malware that infects systems and steals data without installing any file onto the targeted system. Researchers dubbed this  persistent malware as Poweliks , which resides in the computer registry only and is therefore not easily detectable as other typical malware that installs files on the affected system which can be scanned by antivirus or anti-malware Software. According to Paul Rascagneres , Senior Threat Researcher, Malware analyst at GData software, due to the malware's subsequent and step-after-step execution of code, the feature set was similar to a stacking principles of Matryoshka Doll approach. Paul has made a number of name ripping malware and bots to uncover and undermine cyber crimes. He won last
