Several malicious packages have been uncovered across the npm, Python, and Ruby package repositories that drain funds from cryptocurrency wallets, erase entire codebases after installation, and exfiltrate Telegram API tokens, once again demonstrating the variety of supply chain threats lurking in open-source ecosystems. The findings come from multiple reports published by Checkmarx, ReversingLabs, Safety, and Socket in recent weeks. The list of identified packages across these platforms are listed below - Socket noted that the two malicious gems were published by a threat actor under the aliases Bùi nam, buidanhnam, and si_mobile merely days after Vietnam ordered a nationwide ban on the Telegram messaging app late last month for allegedly not cooperating with the government to tackle illicit activities related to fraud, drug trafficking, and terrorism. "These gems silently exfiltrate all data sent to the Telegram API by redirecting traffic through a command-and-control (C2...

Tactics, techniques, and procedures (TTPs) form the foundation of modern defense strategies. Unlike indicators of compromise (IOCs), TTPs are more stable, making them a reliable way to identify specific cyber threats. Here are some of the most commonly used techniques, according to ANY.RUN's Q3 2024 report on malware trends, complete with real-world examples. Disabling of Windows Event Logging (T1562.002) Disrupting Windows Event Logging helps attackers prevent the system from recording crucial information about their malicious actions. Without event logs, important details such as login attempts, file modifications, and system changes go unrecorded, leaving security solutions and analysts with incomplete or missing data. Windows Event Logging can be manipulated in different ways, including by changing registry keys or using commands like "net stop eventlog". Altering group policies is another common method. Since many detection mechanisms rely on log analysis to identify s...

Unknown malware presents a significant cybersecurity threat and can cause serious damage to organizations and individuals alike. When left undetected, malicious code can gain access to confidential information, corrupt data, and allow attackers to gain control of systems. Find out how to avoid these circumstances and detect unknown malicious behavior efficiently.  Challenges of new threats' detection While known malware families are more predictable and can be detected more easily, unknown threats can take on a variety of forms, causing a bunch of challenges for their detection: Malware developers use polymorphism, which enables them to modify the malicious code to generate unique variants of the same malware.  There is malware that is still not identified and doesn't have any rulesets for detection. Some threats can be Fully UnDetectable (FUD) for some time and challenge perimeter security.  The code is often encrypted, making it difficult to detect by signature-...

A New York-based online ad network company AppNexus, that provides a platform specializing in real-time online advertising, has again been spotted as the origin of a recent "malvertising" campaign that makes use of the Angler Exploit Kit to redirect visitors to malicious websites hosting the Asprox malware. AppNexus servers process 16 billion ad buys per day, making it the biggest reach on the open web after Google. Back in May, AppNexus was serving malicious ads targeting Microsoft's Silverlight platform. The world's largest Internet Video Subscription service Netflix runs on Silverlight, and because of its popularity, hackers have been loading exploit kits with Silverlight. As part of this campaign, users of several high-profile websites including Java.com, Deviantart.com, TMZ.com, Photobucket.com, IBTimes.com, eBay.ie, Kapaza.be and TVgids.nl , last week were redirected to websites serving malicious advertisements that infected visitors by installing botnet ma...

Luring users on social media to visit lookalike version of popular websites that pop-up a legitimate-looking Chrome extension installation window is one of the most common modus operandi of cybercriminals to spread malware. Security researchers are again warning users of a new malware campaign that has been active since at least March this year and has already infected more than 100,000 users worldwide. Dubbed Nigelthorn, the malware is rapidly spreading through socially engineered links on Facebook and infecting victims' systems with malicious browser extensions that steal their social media credentials, install cryptocurrency miners, and engage them in click fraud. The malware was pushed through at least seven different Chrome browser extensions—all were hosted on Google's official Chrome Web Store. These malicious Chrome browser extensions were first discovered by researchers at cybersecurity firm Radware, after a "well-protected network" of one of its custo...

If you came across a celebrity sex video on Facebook featuring Jessica Alba or any other celebrity, just avoid clicking it. Another Facebook scam is circulating across the social networking website that attempts to trick Facebook users into clicking on a link for a celebrity sex tape that instead downloads malware onto their computers. Once installed, the malware would force web browsers to display aggressive advertising web pages which include sites with nudity and fake lotteries. The spam campaign was uncovered by researchers at Cyren, who noted that a malicious Google Chrome extension is spreading nude celebrity PDFs through private messages and posts on various Facebook groups. If opened, the PDF file takes victims to a web page with an image containing a play button, tricking users that the PDF may contain a video. Once clicked, the link redirects users of Internet Explorer, Firefox, or Safari to a web page with overly-aggressive popups and advertisements related to ...

Even after so many efforts by Google like launching bug bounty program and preventing apps from using Android accessibility services , malicious applications somehow manage to get into Play Store and infect people with malicious software. The same happened once again when security researchers discovered at least 85 applications in Google Play Store that were designed to steal credentials from users of Russian-based social network VK.com and were successfully downloaded millions of times. The most popular of all masqueraded as a gaming app with more than a million downloads. When this app was initially submitted in March 2017, it was just a gaming app without any malicious code, according to a blog post published Tuesday by Kaspersky Lab. However, after waiting for more than seven months, the malicious actors behind the app updated it with information-stealing capabilities in October 2017. Besides this gaming app, the Kaspersky researchers found 84 such apps on Google Play ...

Cybersecurity researchers have discovered a new malicious package on the Python Package Index (PyPI) repository that impersonates a software development kit (SDK) for SentinelOne, a major cybersecurity company, as part of a campaign dubbed  SentinelSneak . The package, named  SentinelOne  and now taken down, is said to have been published between December 8 and 11, 2022, with nearly two dozen versions pushed in quick succession over a period of two days. It claims to offer an easier method to access the  company's APIs , but harbors a malicious backdoor that's engineered to amass sensitive information from development systems, including access credentials, SSH keys, and configuration data. What's more, the threat actor has also been observed releasing two more packages with similar naming variations –  SentinelOne-sdk  and  SentinelOneSDK  – underscoring the  continued threats  lurking in open source repositories. "The SentinelOne ...

Cybersecurity researchers have disclosed a malicious package uploaded to the Python Package Index (PyPI) repository that's designed to reroute trading orders placed on the MEXC cryptocurrency exchange to a malicious server and steal tokens. The package, ccxt-mexc-futures, purports to be an extension built on top of a popular Python library named ccxt (short for CryptoCurrency eXchange Trading), which is used to connect and trade with several cryptocurrency exchanges and facilitate payment processing services. The malicious package is no longer available on PyPI, but statistics on pepy.tech shows that it has been downloaded at least 1,065 times . "The authors of the malicious ccxt-mexc-futures package, claim in its README file that it extends the CCXT package to support 'futures' trade on MEXC," JFrog researcher Guy Korolevski said in a report shared with The Hacker News. However, a deeper examination of the library has revealed that it specifically overr...

Threat actors have been observed uploading malicious typosquats of legitimate npm packages such as typescript-eslint and @types/node that have racked up thousands of downloads on the package registry. The counterfeit versions, named @typescript_eslinter/eslint and types-node , are engineered to download a trojan and retrieve second-stage payloads, respectively. "While typosquatting attacks are hardly new, the effort spent by nefarious actors on these two libraries to pass them off as legitimate is noteworthy," Sonatype's Ax Sharma said in an analysis published Wednesday. "Furthermore, the high download counts for packages like "types-node" are signs that point to both some developers possibly falling for these typosquats, and threat actors artificially inflating these counts to boost the trustworthiness of their malicious components." The npm listing for @typescript_eslinter/eslint, Sonatype's analysis revealed, points to a phony GitHub repo...

Cybersecurity researchers have called attention to a software supply chain attack targeting the Go ecosystem that involves a malicious package capable of granting the adversary remote access to infected systems. The package, named github.com/boltdb-go/bolt , is a typosquat of the legitimate BoltDB database module ( github.com/boltdb/bolt ), per Socket. The malicious version (1.3.1) was published to GitHub in November 2021, following which it was cached indefinitely by the Go Module Mirror service. "Once installed, the backdoored package grants the threat actor remote access to the infected system, allowing them to execute arbitrary commands," security researcher Kirill Boychenko said in an analysis. Socket said the development marks one of the earliest instances of a malicious actor abusing the Go Module Mirror's indefinite caching of modules to trick users into downloading the package. Subsequently, the attacker is said to have modified the Git tags in the source r...

Researchers have discovered over 100 malicious nodes on the Tor anonymity network that are "misbehaving" and potentially spying on Dark Web sites that use Tor to mask the identities of their operators. Two researchers, Amirali Sanatinia and Guevara Noubir, from Northwestern University, carried out an experiment on the Tor Network for 72 days and discovered at least 110 malicious Tor Hidden Services Directories (HSDirs) on the network. The nodes, also known as the Tor hidden services directories ( HSDirs ) are servers that act as introductory points and are configured to receive traffic and direct users to hidden services (" .onion " addresses). In other words, the hidden services directory or HSDir is a crucial element needed to mask the true IP address of users on the Tor Network. But, here's the issue: HSDir can be set up by anyone. "Tor's security and anonymity is based on the assumption that the large majority of its relays are honest and...
