A team of security researchers from Cybellum, an Israeli zero-day prevention firm, has discovered a new Windows vulnerability that could allow hackers to take full control of your computer. Dubbed DoubleAgent , the new injecting code technique works on all versions of Microsoft Windows operating systems, starting from Windows XP to the latest release of Windows 10. What's worse? DoubleAgent exploits a 15-years-old undocumented legitimate feature of Windows called " Application Verifier ," which cannot be patched. Application Verifier is a runtime verification tool that loads DLLs (dynamic link library) into processes for testing purpose, allowing developers quickly detect and fix programming errors in their applications. Unpatchable Microsoft Application Verifier Exploit The vulnerability resides in how this Application Verifier tool handles DLLs. According to the researchers, as part of the process, DLLs are bound to the target processes in a Windows Regist...

Guess what's more expensive than counterfeit United States passports, stolen credit cards and even guns on the dark web? It's digital code signing certificates. A recent study conducted by the Cyber Security Research Institute (CSRI) this week revealed that stolen digital code-signing certificates are readily available for anyone to purchase on the dark web for up to $1,200. As you may know, digital certificates issued by a trusted certificate authority (CA) are used to cryptographically sign computer applications and software, and are trusted by your computer for execution of those programs without any warning messages. However, malware author and hackers who are always in search of advanced techniques to bypass security solutions have been abusing trusted digital certificates during recent years. Hackers use compromised code signing certificates associated with trusted software vendors in order to sign their malicious code, reducing the possibility of their malw...

Security researchers have discovered multiple attack campaigns conducted by an established Chinese criminal group that operates worldwide, targeting database servers for mining cryptocurrencies, exfiltrating sensitive data and building a DDoS botnet. The researchers from security firm GuardiCore Labs have analyzed thousands of attacks launched in recent months and identified at least three attack variants— Hex, Hanako, and Taylor —targeting different MS SQL and MySQL servers for both Windows and Linux. The goals of all the three variants are different—Hex installs cryptocurrency miners and remote access trojans (RATs) on infected machines, Taylor installs a keylogger and a backdoor, and Hanako uses infected devices to build a DDoS botnet. So far, researchers have recorded hundreds of Hex and Hanako attacks and tens of thousands of Taylor attacks each month and found that most compromised machines are based in China, and some in Thailand, the United States, Japan and others. ...

New variants of a banking malware called Grandoreiro have been found to adopt new tactics in an effort to bypass anti-fraud measures, indicating that the malicious software is continuing to be actively developed despite law enforcement efforts to crack down on the operation. "Only part of this gang was arrested: the remaining operators behind Grandoreiro continue attacking users all over the world, further developing new malware and establishing new infrastructure," Kaspersky said in an analysis published Tuesday. Some of the other freshly incorporated tricks include the use of a domain generation algorithm (DGA) for command-and-control (C2) communications, ciphertext stealing ( CTS ) encryption, and mouse tracking. Also observed are "lighter, local versions" that are specifically focused on targeting banking customers in Mexico. Grandoreiro , active since 2016, has consistently evolved over time, taking efforts to stay undetected, while also widening its geog...

Due to the recent surge in cryptocurrency prices, not only hackers but also legitimate website administrators are increasingly using JavaScript-based cryptocurrency miners to monetize by levying the CPU power of your PC to mine Bitcoin or other cryptocurrencies. Just last week, researchers from AdGuard discovered that some popular video streaming and ripper sites including openload, Streamango, Rapidvideo, and OnlineVideoConverter hijacks CPU cycles from their over hundreds of millions of visitors for mining Monero cryptocurrency. Now, researchers from Moscow-based cyber security firm Kaspersky Lab have uncovered a new strain of Android malware lurking in fake anti-virus and porn applications, which is capable of performing a plethora of nefarious activities—from mining cryptocurrencies to launching Distributed Denial of Service (DDoS) attacks. Dubbed Loapi , the new Android Trojan can perform so many more malicious activities at a time that can exploit a handset to the e...

Cybersecurity researchers have discovered a new Raspberry Robin campaign wave that has been propagating the malware through malicious Windows Script Files ( WSFs ) since March 2024. "Historically, Raspberry Robin was known to spread through removable media like USB drives, but over time its distributors have experimented with other initial infection vectors," HP Wolf Security researcher Patrick Schläpfer  said  in a report shared with The Hacker News. Raspberry Robin, also called QNAP worm, was  first spotted  in September 2021 that has since  evolved into a downloader  for various other payloads in recent years, such as SocGholish, Cobalt Strike, IcedID, BumbleBee, and TrueBot, and also serving as a precursor for ransomware. While the malware was initially distributed by means of USB devices containing LNK files that retrieved the payload from a compromised QNAP device, it has since  adopted other methods  such as social engineering and malv...
