New Flaws in Top Antivirus Software Could Make Computers More Vulnerable

October 05, 2020Ravie Lakshmanan
Cybersecurity researchers today disclosed details of security vulnerabilities found in popular antivirus solutions that could enable attackers to elevate their privileges, thereby helping malware sustain its foothold on the compromised systems. According to a report published by CyberArk researcher Eran Shimony today and shared with The Hacker News, the high privileges often associated with anti-malware products render them more vulnerable to exploitation via file manipulation attacks, resulting in a scenario where malware gains elevated permissions on the system. The bugs impact a wide range of antivirus solutions, including those from Kaspersky, McAfee, Symantec, Fortinet, Check Point, Trend Micro, Avira, and Microsoft Defender, each of which has been fixed by the respective vendor. Chief among the flaws is the ability to delete files from arbitrary locations, allowing the attacker to delete any file in the system, as well as a file corruption vulnerability that permits a bad ac

How Organizations Can Defend Against Advanced Persistent Threats

How Organizations Can Defend Against Advanced Persistent Threats

December 25, 2019The Hacker News
Advanced persistent threats (APTs) have emerged to be legitimate concerns for all organizations. APTs are threat actors that breach networks and infrastructures and stealthily lurk within them over extended spans of time. They typically perform complex hacks that allow them to steal or destroy data and resources. According to Accenture , APTs have been organizing themselves into groups that enable them to share tactics and tools to carry out attacks at scale. Russian group Silence APT, for instance, has been reported to be actively targeting financial institutions and have successfully stolen millions of dollars from various banks worldwide. Smaller organizations also need to be wary of such threats. APT groups also use automated tools and botnets to gain access to networks, and these tactics don't discriminate based on size, industry, or value. Any vulnerable infrastructure can be breached. It is now critical for all organizations to understand how APTs operate and impleme
Snatch Ransomware Reboots Windows in Safe Mode to Bypass Antivirus

Snatch Ransomware Reboots Windows in Safe Mode to Bypass Antivirus

December 10, 2019Mohit Kumar
Cybersecurity researchers have spotted a new variant of the Snatch ransomware that first reboots infected Windows computers into Safe Mode and only then encrypts victims' files to avoid antivirus detection. Unlike traditional malware, the new Snatch ransomware chooses to run in Safe Mode because in the diagnostic mode Windows operating system starts with a minimal set of drivers and services without loading most of the third-party startup programs, including antivirus software. Snatch has been active since at least the summer of 2018, but SophosLabs researchers spotted the Safe Mode enhancement to this ransomware strain only in recent cyber attacks against various entities they investigated. "SophosLabs researchers have been investigating an ongoing series of ransomware attacks in which the ransomware executable forces the Windows machine to reboot into Safe Mode before beginning the encryption process," the researchers say . "The ransomware, which calls it

Rogue TrendMicro Employee Sold Customer Data to Tech Support Scammers

November 07, 2019Wang Wei
Do you always uncomfortable trusting companies with your data? If so, you're not alone. While companies do much to protect themselves from external threats, insiders always pose the highest risk to a company's data. Unfortunately, when we say companies can't eliminate insider threat completely, cybersecurity firms, who are meant to protect others, are not an exception. Cybersecurity firm Trend Micro has disclosed a security incident this week carried out by an employee who improperly accessed the personal data of thousands of its customers with a "clear criminal intent" and then sold it to a malicious third-party tech support scammers earlier this year. According to the security company, an estimated number of customers affected by the breach is 68,000, which is less than one percent of the company's 12 million customer base. Trend Micro first became aware of the incident in early August 2019 when it found that some of its consumer customers were r

Breaches are now commonplace, but Reason Cybersecurity lets users guard their privacy

October 09, 2019The Hacker News
There has been no shortage of massive security breaches so far this year. Just last July, Capital One disclosed that it was hit by a breach that affected more than 100 million customers. Also recently, researchers came across an unsecured cloud server that contained the names, phone numbers, and financial information of virtually all citizens of Ecuador – around 20 million people . These are just the latest in a long line of security breaches affecting enterprises over the past few years. The Yahoo!, Equifax, and Marriott hacks and Facebook's scandal should still be fresh in people's memories, reminding everyone that even large corporations with budgets for enterprise cybersecurity may not be secure enough to protect customer information. These records are now out there, stored in hackers' data dumps , and are potentially tradable over the Dark Web. The availability of such information online increases a person's risk of being victimized through fraud and iden

Advanced Breach Protection Demystified – Untold Truths On Security Beyond AV

March 28, 2019The Hacker News
Doing business in today's connected world means dealing with a continually evolving threat landscape. With potential losses due to downtime following a breach, plus valuable client and proprietary information at risk, most organizations realize they cannot afford to be complacent. This puts extra onus on security IT teams, who are continuously left scrambling, looking for the best way to protect their organizations against the threats that bypass AV and firewall. Added to this is another challenge in that most organizations are limited in the resources they can invest in security. Many are left reliant on a single product on top of their security stack. Common practice in organizational security circles as they attempt to remain secure is to upgrade endpoint protection with EPP\EDR or a Network Analytic tool. But as we all know, what's common is not necessarily what's best. How can an organization ensure it remains secure, especially with all that is at stake?

Microsoft Announces Windows Defender ATP Antivirus for Mac

March 22, 2019Mohit Kumar
Brace yourself guys. Microsoft is going to release its Windows Defender ATP antivirus software for Mac computers. Sounds crazy, right? But it's true. Microsoft Thursday announced that the company is bringing its anti-malware software to Apple's macOS operating system as well—and to more platforms soon, like Linux. As a result, the technology giant renamed its Windows Defender Advanced Threat Protection (ATP) to Microsoft Defender Advanced Threat Protection (ATP) in an attempt to minimize name-confusion and reflect the cross-platform nature of the software suite. But wait, does your Macbook need antivirus protection? Of course! For all those wondering if Mac even gets viruses—macOS is generally more secure than Windows, but in recent years cybercriminals have started paying attention to the Mac platform, making it a new target for viruses, Trojans, spyware, adware, ransomware, backdoors, and other nefarious applications. Moreover, hackers have been successful many ti
Windows Built-in Antivirus Gets Secure Sandbox Mode – Turn It ON

Windows Built-in Antivirus Gets Secure Sandbox Mode – Turn It ON

October 29, 2018Mohit Kumar
Microsoft Windows built-in anti-malware tool, Windows Defender, has become the very first antivirus software to have the ability to run inside a sandbox environment. Sandboxing is a process that runs an application in a safe environment isolated from the rest of the operating system and applications on a computer. So that if a sandboxed application gets compromised, the technique prevents its damage from spreading outside the closed area. Since antivirus and anti-malware tools run with the highest level of privileges to scan all parts of a computer for malicious code, it has become a desired target for attackers. The need for sandboxing an antivirus tool has become necessary after multiple critical vulnerabilities were discovered in such powerful applications, including Windows Defender, in past years that could have allowed attackers to gain full control of a targeted system. That's why Microsoft announced to add a sandbox mode to its Windows Defender. So, even if an att

Operator of VirusTotal Like Malware-Scanning Service Jailed for 14 Years

September 22, 2018Mohit Kumar
A Latvian hacker behind the development and operation of counter antivirus service "Scan4You" has finally been sentenced to 14 years in prison. 37-year-old Ruslans Bondars, described as a Latvian "non-citizen" or "citizen of the former USSR who had been residing in Riga, Latvia," was found guilty on May 16 in federal court in Alexandria, during which a co-conspirator revealed he had worked with Russian law enforcement. Bondars created and ran Scan4you—a VirusTotal like online multi-engine antivirus scanning service that allowed hackers to run their code by several popular antiviruses to determine if their computer virus or malware would be flagged during routine security scans before launching them into a real-world malware campaign. While legal scanning services share data about uploaded files with the antivirus firms, Scan4you instead informed its users that they could "upload files anonymously and promised not to share information about the

Process Doppelgänging: New Malware Evasion Technique Works On All Windows Versions

December 07, 2017Mohit Kumar
A team of security researchers has discovered a new malware evasion technique that could help malware authors defeat most of the modern antivirus solutions and forensic tools. Dubbed Process Doppelgänging , the new fileless code injection technique takes advantage of a built-in Windows function and an undocumented implementation of Windows process loader. Ensilo security researchers Tal Liberman and Eugene Kogan, who discovered the Process Doppelgänging attack, presented their findings today at Black Hat 2017 Security conference held in London. Process Doppelgänging Works on All Windows Versions Apparently, Process Doppelgänging attack works on all modern versions of Microsoft Windows operating system, starting from Windows Vista to the latest version of Windows 10. Tal Liberman, the head of the research team at enSilo, told The Hacker New that this malware evasion technique is similar to Process Hollowing—a method first introduced years ago by attackers to defeat the m

Google to Block Third-Party Software from Injecting Code into Chrome Browser

November 30, 2017Swati Khandelwal
To improve performance and reduce crashes caused by third-party software on Windows, Google Chrome, by mid-2018, will no longer allow outside applications to run code within its web browser. If you are unaware, many third-party applications, like accessibility or antivirus software, inject code into your web browser for gaining more control over your online activities in order to offer some additional features and function properly. However, Google notes that over 15 percent of Chrome users running third-party applications on their Windows machines that inject code into their web browsers experience crashes—and trust me it's really annoying. But don't you worry. Google now has a solution to this issue. In a blog post published Thursday on Chromium Blog, Google announced its plan to block third-party software from injecting code into Chrome—and these changes will take place in three steps: April 2018 — With the release of Chrome 66, Google will begin informing use

The Rise of Super-Stealthy Digitally Signed Malware—Thanks to the Dark Web

November 06, 2017Swati Khandelwal
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

How Top Companies Accidentally Leaking Terabytes of Sensitive Data Online

August 09, 2017Swati Khandelwal
An anti-malware detection service provider and premium security firm has been accused of leaking terabytes of confidential data from several Fortune 1000 companies, including customer credentials, financial records, network intelligence and other sensitive data. However, in response to the accusations, the security firm confirmed that they are not pulling sensitive files from its customers; instead, it's up to companies—who are accidentally (but explicitly) sharing their sensitive data to leverage an optional cloud-based anti-malware service. On Wednesday, Information security firm DirectDefense published a blog post, claiming that they found a major issue with endpoint detection and response (EDR) solution offered by US-based company Carbon Black, alleging that the company is leaking hundreds of thousands of sensitive files from its customers. Carbon Black is a leading incident response and threat hunting company that offers security products to nearly thirty of the larg
