Browser-based botnets are the T-1000s of the DDoS world. Just like the iconic villain of the old Judgment Day movie, they too are designed for adaptive infiltration. This is what makes them so dangerous. Where other more primitive bots would try to brute-force your defenses, these bots can simply mimic their way through the front gate. By the time you notice that something`s wrong, your perimeter has already been breached, your servers were brought down, and there is little left to do but to hang up and move on. So how do you flush out a T-1000? How do you tell a browser-based bot from a real person using a real browser? Some common bot filtering methods, which usually rely on sets of Progressive Challenges , are absolutely useless against bots that can retain cookies and execute JavaScripts. The alternative to indiscriminately flashing CAPTCHA's for anyone with a browser is nothing less than a self-inflicted disaster - especially when the attacks can go on for weeks a

Russian Security Firm Kaspersky Lab has revealed that it has been following a sustained attack on South Korea by hackers seemingly based in North Korea.,  This new Cyber Espionage campaign dubbed "Kimsuky"  has targeted several South Korean think tanks. R esearchers believe the Kimsuky malware is most likely delivered via spear-phishing e-mails  and used multiple Dropbox email accounts "It's interesting that the drop box mail accounts iop110112@hotmail.com and rsh1213@hotmail.com are registered with the following "kim" names: kimsukyang and "Kim asdfa " The Kaspersky researchers revealed that the operation presents distinctive characteristics in its execution and logistics. The investigation started after the team of experts detected an unsophisticated spy program that communicated with it control server via a public e-mail server, an approach followed by too many amateur malware authors. Victims download a Trojan dropper which is used to download additional malwa

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Once again NSA whistleblower Edward Snowden revealed the truth, that the NSA hacks into China's mobile operators to steal millions of text messages.  Every month Washington come up with new reports  and accuse other nations, particularly China, for cyber hacking , but the biggest culprit of such crime is in fact the United States. All of this appeared to go relatively well for Washington until revelations emerged of the U.S. National Security Agency's PRISM surveillance program . According to Snowden, U.S. spies had hacked 3 major mobile phone companies in China and a core network to steal text messages of millions of Chinese citizens. Fang Binxing, a President at Beijing University who is considered the chief pioneer of China's Great Firewall Internet filtering system, has warned in the past that telecom equipment from international companies like Cisco is a threat to China's national security. As such, it could have allowed NSA operatives to access int

ModSecurity is an open source web application firewall. It provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis. ModSecurity developers team recently fixed a vulnerability ( CVE-2013-2765 ) which could be exploited by attackers to crash the firewall . The vulnerability is caused due to an error when processing the " forceRequestBodyVariable " action and can be exploited to cause a NULL pointer dereference via specially crafted HTTP requests.  Flaw was reported by Younes Jaaidi, according to him an attacker can exploit this issue using a web browser. He also released an Exploit for this flaw, which is publicly available at  Github  for download. Through the program to upgrade to version 2.7.4 fixes this problem, this version also fixes some minor bug and lib injection used to identify SQL injection attacks, while the development team also announced its portable version of Nginx has

The hardware qualification is a very important issue, recent vulnerabilities discovered in network appliances of various manufacturer have alerted security community once again on the necessity to validate the hardware especially for large consume product. The last news is related to a vulnerability related to the Intel's 82574L Ethernet controller that expose equipment to risk of "packet of death." Attack. Star2Star 's chief technology officer Kristian Kielhofner identified the cause of the problems after customers experienced random crashes. Researchers at Star2Star after the analysis of lot traffic identified the cause of the problem in the format of a packet managed by a particular VoIP manufacturer. But as yet it is unclear how widespread the problem is or how other Intel hardware is affected. Kielhofner, wrote : " The system and Ethernet interfaces would appear fine," "and then after a random amount of traffic the interface woul
