Here's how hackers are targeting Cisco Network Switches in Russia and Iran

April 09, 2018Mohit Kumar
Since last week, a new hacking group, calling itself ' JHT ,' hijacked a significant number of Cisco devices belonging to organizations in Russia and Iran, and left a message that reads—" Do not mess with our elections " with an American flag (in ASCII art). MJ Azari Jahromi, Iranian Communication and Information Technology Minister, said the campaign impacted approximately 3,500 network switches in Iran, though a majority of them were already restored. The hacking group is reportedly targeting vulnerable installations of Cisco Smart Install Client, a legacy plug-and-play utility designed to help administrators configure and deploy Cisco equipments remotely, which is enabled by default on Cisco IOS and IOS XE switches and runs over TCP port 4786. Some researchers believe the attack involves a recently disclosed remote code execution vulnerability ( CVE-2018-0171 ) in Cisco Smart Install Client that could allow attackers to take full control of the network

How to Mitigate the Threat Cryptocurrency Mining Poses to Enterprise Security

February 05, 2018Swati Khandelwal
The growing popularity of Bitcoin and other cryptocurrencies is generating curiosity—and concern—among security specialists. Crypto mining software has been found on user machines, often installed by botnets. Organizations need to understand the risks posed by this software and what actions, if any, should be taken. To better advise our readers, we reached out to the security researchers at Cato Networks. Cato provides a cloud-based SD-WAN that includes FireWall as a Service (FWaaS) . Its research team, Cato Research Labs, maintains the company's Cloud IPS, and today released a list of crypto mining pool addresses that you can use as a blacklist in your firewall. (To download the list, visit this page .) Cato Research Labs determined crypto mining represents a moderate threat to the organization. Immediate disruption of the organization infrastructure or loss of sensitive data is not likely to be a direct outcome of crypto mining. However, there are significant risks of i
What is the hype around Firewall as a Service?

What is the hype around Firewall as a Service?

July 10, 2017Mohit Kumar
Admit it. Who would not want their firewall maintenance grunt work to go away? For more than 20 years, companies either managed their edge firewall appliances or had service providers rack-and-stack appliances in their data centers and did it for them. This was called a managed firewall — an appliance wrapped with a managed service, often from a carrier or managed security service provider (MSSP). The provider assumed the management of the firewall box, its software, and even its policy and management from the over-burdened IT team. But customers ended up paying for the inefficiency of dealing with appliances (i.e. “grunt work”) because the problem just shifted to the provider. A new architecture was needed - a transformation from an appliance form factor to a true cloud service. In a 2016 Hype Cycle for Infrastructure Protection report , Gartner analyst Jeremy D'Hoinne initiated the emerging category of Firewall as a Service (FWaaS). He defined FWaaS as “ ...a fire
Unpatched Python and Java Flaws Let Hackers Bypass Firewall Using FTP Injection

Unpatched Python and Java Flaws Let Hackers Bypass Firewall Using FTP Injection

February 21, 2017Swati Khandelwal
This newly discovered bugs in Java and Python is a big deal today. The two popular programming languages, Java and Python, contain similar security flaws that can be exploited to send unauthorized emails and bypass any firewall defenses. And since both the flaws remain unpatched, hackers can take advantage to design potential cyber attack operations against critical networks and infrastructures. The unpatched flaws actually reside in the way Java and Python programming languages handle File Transfer Protocol (FTP) links, where they don't syntax-check the username parameter, which leads to, what researchers call, protocol injection flaw. Java/Python FTP Injection to Send Unauthorized SMTP Emails In a blog pos t published over the past week, security researcher Alexander Klink detailed the FTP protocol injection vulnerability in Java's XML eXternal Entity (XXE) that allows attackers to inject non-FTP malicious commands inside an FTP connection request. To demonst
Simplifying SSH keys and SSL Certs Management across the Enterprise using Key Manager Plus

Simplifying SSH keys and SSL Certs Management across the Enterprise using Key Manager Plus

November 02, 2016Swati Khandelwal
With rapidly growing web-based services and widely expanding locations, organizations are using more and more SSL certificates as well as SSH keys than ever. From authentication, confidentiality, and integrity to preventing the organization from industrial espionage, SSL certificates play an important role. Managing SSL certificates across networks to ensure protection and prevent unanticipated failures is critical, and it also becomes complicated with multiple locations, divisions as well as the fastest growing use of external cloud-based services. This not only complicates the process of managing individual SSL certificate and SSH key for an administrator but also costs organizations heavily. A key solution for this issue is to use an advanced and efficient SSL certificate and SSH Key management system. An effective solution enables an organization to know what kinds of certificates and keys it has, simplifies certificate discovery and monitor across multiple vendors, an
Facebook releases Osquery Security Tool for Windows

Facebook releases Osquery Security Tool for Windows

September 27, 2016Swati Khandelwal
OSquery , an open-source framework created by Facebook that allows organizations to look for potential malware or malicious activity on their networks, was available for Mac OS X and Linux environments until today. But now the social network has announced that the company has developed a Windows version of its osquery tool , too. When Facebook engineers want to monitor thousands of Apple Mac laptops across their organization, they use their own untraditional security tool called OSquery. OSquery is a smart piece of cross-platform software that scans every single computer on an infrastructure and catalogs every aspect of it. Then SQL-based queries allow developers and security teams to monitor low-level functions in real-time and quickly search for malicious behavior and vulnerable applications on their infrastructure. In simple words, OSquery allows an organization to treat its infrastructure as a database, turning OS information into a format that can be queried using SQL

Here's How SIEM Can Protect Your Privileged Accounts in the Enterprise

Here's How SIEM Can Protect Your Privileged Accounts in the Enterprise

October 20, 2015Wang Wei
It’s inevitable. Most security threats eventually target privileged accounts. In every organization each user has different permissions, and some users hold the metaphorical keys to your IT kingdom. If the privileged accounts get compromised, it can lead to theft or sabotage. Because these accounts control delicate parts of your IT operations, and it is important to know who has privileges, what privileges they have, when they received access, and what activity they’ve done. This is where Security Information and Event Management (SIEM) software comes in handy. SIEM Monitors and Alerts on Privileged Account Activity Comprehensive monitoring of privileged accounts can be challenging because you need to monitor users who are administrators, users with root access, and users with access to firewalls, databases, services, automated processes, etc. With every additional user, group, and policy monitoring account activity gets increasingly difficult. On top of mo
Volatile Cedar — Global Cyber Espionage Campaign Discovered

Volatile Cedar — Global Cyber Espionage Campaign Discovered

May 29, 2015Wang Wei
Security firm Check Point has uncovered what seems to be a successful, and long-running, cyber-surveillance campaign called “ Volatile Cedar .” Check Point found that targets of the attack included, but were not limited to, defense contractors, media companies, telecommunications, and educational institutions. The attack is said to have originated in Lebanon and possibly has political ties in the region. According to an article in Techworld , previous cyber-campaigns originating from Lebanon have been either extremely unsophisticated or targeted at other countries in the region. However, Volatile Cedar is different. According to the report, this campaign has been in operation since 2012 and has successfully penetrated a large number of targets across the globe. During this time it has allowed the attackers to steal data and monitor a large volume of victim’s actions. The actors involved in this campaign do not appear to be using flashy mechanisms like zero day attacks

USB Defense: Stop Data Walking Out The Door

April 17, 2015Wang Wei
The bad news is that internal data breaches are on the rise. And one of the biggest culprits? USB devices. In the past few years, there has been many organizations tracking down the loss of sensitive/confidential information due to the usage of USB drives and other mass storage media. Cyber-security breaches and data theft are making more and more IT leaders paranoid about security than ever before. Why are USB devices dangerous? USB devices can hold a lot of information. For example, a 128 GB USB flash drive can store 60,000 photos, 20,000 songs, 100+ videos, and more. Just imagine how many protected corporate files could fit on one drive. Also, the storage capacity of USB devices is only going to increase. USB devices are super portable. Some USB storage devices are the size of a small coin. This makes them very difficult to visually detect when plugged into an open port. USB devices are cheap and easy to find. If you’re in the market for a USB storage device, there
