7 Ways Hackers and Scammers Are Exploiting Coronavirus Panic

7 Ways Hackers and Scammers Are Exploiting Coronavirus Panic

April 09, 2020Ravie Lakshmanan
In our previous stories, you might have already read about various campaigns warning how threat actors are capitalizing on the ongoing coronavirus pandemic in an attempt to infect your computers and mobile devices with malware or scam you out of your money. Unfortunately, to some extent, it's working, and that's because the attack surface is changing and expanding rapidly as many organizations and business tasks are going digital without much preparation, exposing themselves to more potential threats. Most of the recent cyberattacks are primarily exploiting the fears around the COVID-19 outbreak—fueled by disinformation and fake news—to distribute malware via Google Play apps , malicious links and attachments, and execute ransomware attacks. Here, we took a look at some of the wide range of unseen threats rising in the digital space, powered by coronavirus-themed lures that cybercriminals are using for espionage and commercial gain. The latest development adds to a l

Dark Nexus: A New Emerging IoT Botnet Malware Spotted in the Wild

April 08, 2020Ravie Lakshmanan
Cybersecurity researchers have discovered a new emerging IoT botnet threat that leverages compromised smart devices to stage ' distributed denial-of-service ' attacks, potentially triggered on-demand through platforms offering DDoS-for-hire services. The botnet, named "dark_nexus" by Bitdefender researchers, works by employing credential stuffing attacks against a variety of devices, such as routers (from Dasan Zhone, Dlink, and ASUS), video recorders, and thermal cameras, to co-opt them into the botnet. So far, dark_nexus comprises at least 1,372 bots, acting as a reverse proxy, spanning across various locations in China, South Korea, Thailand, Brazil, and Russia. "While it might share some features with previously known IoT botnets, the way some of its modules have been developed makes it significantly more potent and robust," the researchers said . "For example, payloads are compiled for 12 different CPU architectures and dynamically deliver

Unveiled: How xHelper Android Malware Re-Installs Even After Factory Reset

April 07, 2020Mohit Kumar
Remember xHelper? A mysterious piece of Android malware that re-installs itself on infected devices even after users delete it or factory reset their devices—making it nearly impossible to remove. xHelper reportedly infected over 45,000 devices last year, and since then, cybersecurity researchers have been trying to unfold how the malware survives factory reset and how it infected so many devices in the first place. In a blog post published today, Igor Golovin, malware analyst at Kaspersky, finally solved the mystery by unveiling technical details on the persistence mechanism used by this malware, and eventually also figured out how to remove xHelper from an infected device completely. As the initial attack vector and for distribution, the malware app disguises itself as a popular cleaner and speed optimization app for smartphones — affecting mostly users in Russia (80.56%), India (3.43%), and Algeria (2.43%). "But in reality, there is nothing useful about it: af

Secure Remote Working During COVID-19 — Checklist for CISOs

April 07, 2020The Hacker News
Coronavirus crisis introduces a heavy burden on the CISOs with the collective impact of a mass transition to working remotely coupled with a surge of cyberattacks that strive to monetize the general chaos. Security vendors, unintendedly, contribute to this burden by a relentless generation of noise in the form of attack reports, best practices, tips, and threat landscape analysis. Here we have a new " CISO Checklist for Secure Remote Working " ( download here ) that has been built to assist CISOs in navigating through this noise, providing them with a concise and high-level list of the absolute essentials needed to ensure their organization is well protected in these challenging times. The Coronavirus quarantine forces us to face a new reality. It is critical to acknowledge this new reality in order to understand how to successfully confront these changes. Make no mistake – these changed apply to any organization, regardless of its former security posture. For exa
Zoom Caught in Cybersecurity Debate — Here's Everything You Need To Know

Zoom Caught in Cybersecurity Debate — Here's Everything You Need To Know

April 06, 2020Ravie Lakshmanan
Over the past few weeks, the use of Zoom video conferencing software has exploded ever since it emerged the platform of choice to host everything from cabinet meetings to yoga classes amidst the ongoing coronavirus outbreak and work from home became the new normal. The app has skyrocketed to 200 million daily users from an average of 10 million in December — along with a 535 percent increase in daily traffic to its download page in the last month — but it's also seen a massive uptick in Zoom's problems, all of which stem from sloppy design practices and security implementations. Zoom may never have designed its product beyond enterprise chat initially, but with the app now being used in a myriad number of ways and by regular consumers, the company's full scope of gaffes have come into sharp focus — something it was able to avoid all this time. But if this public scrutiny can make it a more secure product, it can only be a good thing in the long run. A Laundry
How Just Visiting A Site Could Have Hacked Your iPhone or MacBook Camera

How Just Visiting A Site Could Have Hacked Your iPhone or MacBook Camera

April 02, 2020Ravie Lakshmanan
If you use Apple iPhone or MacBook, here we have a piece of alarming news for you. Turns out merely visiting a website — not just malicious but also legitimate sites unknowingly loading malicious ads as well — using Safari browser could have let remote attackers secretly access your device's camera, microphone, or location, and in some cases, saved passwords as well. Apple recently paid a $75,000 bounty reward to an ethical hacker, Ryan Pickren , who practically demonstrated the hack and helped the company patch a total of seven new vulnerabilities before any real attacker could take advantage of them. The fixes were issued in a series of updates to Safari spanning versions 13.0.5 (released January 28, 2020) and Safari 13.1 (published March 24, 2020). "If the malicious website wanted camera access, all it had to do was masquerade as a trusted video-conferencing website such as Skype or Zoom," Pickren said. When chained together, three of the reported Safari
Magecart Hackers Inject iFrame Skimmers in 19 Sites to Steal Payment Data

Magecart Hackers Inject iFrame Skimmers in 19 Sites to Steal Payment Data

April 02, 2020Ravie Lakshmanan
Cybersecurity researchers today uncovered an ongoing new Magecart skimmer campaign that so far has successfully compromised at least 19 different e-commerce websites to steal payment card details of their customers. According to a report published today and shared with The Hacker News, RiskIQ researchers spotted a new digital skimmer, dubbed " MakeFrame ," that injects HTML iframes into web-pages to phish payment data. MakeFrame attacks have been attributed to Magecart Group 7 for its approach of using the compromised sites to host the skimming code, load the skimmer on other compromised websites, and siphon off the stolen data. Magecart attacks usually involve bad actors compromising a company's online store to siphon credit card numbers and account details of users who're making purchases on the infected site by placing malicious JavaScript skimmers on payment forms. It's the latest in a series of attacks by Magecart, an umbrella term for eight diffe
