Company Detected Years-Long Breach Only After Hacker Maxed Out Servers' Storage

Company Detected Years-Long Breach Only After Hacker Maxed Out Servers' Storage

November 14, 2019Wang Wei
What could be even worse than getting hacked? It's the "failure to detect intrusions" that always results in huge losses to the organizations. Utah-based technology company InfoTrax Systems is the latest example of such a security blunder, as the company was breached more than 20 times from May 2014 until March 2016. What's ironic is that the company detected the breach only after it received an alert that its servers had reached maximum storage capacity due to a data archive file that the hacker created. InfoTrax Systems is an American company based in Utah that provides backend operations systems to multi-level marketers, which also includes an extensive amount of sensitive data on their users' compensation, inventory, orders, and accounting. The breach reportedly occurred in May 2014 when the hacker exploited vulnerabilities in InfoTrax's server and its client's website to gain remote control over its server, allowing him to gain access t

University Pays Hackers $20,000 to get back its Ransomware Infected Files

What's the worst that could happen when a Ransomware malware hits University? Last month, the IT department of the University from where I have done my graduation called me for helping them get rid of a Ransomware infection that locked down all its student's results just a day before the announcement. Unfortunately, there was no decrypter available for that specific ransomware sample, but luckily they had the digital backup for the examination results in the form of hundreds of excel sheets. So, somehow backup helped administrator to re-compile complete result once again into the database, but this delayed the announcement for over 30 days. However, the situation is not same every time. Recently, the University of Calgary in Alberta  paid a ransom of $20,000 to decrypt their computer systems' files and regain access to its own email system after getting hit by a ransomware infection. The University fell victim to ransomware last month, when the malware instal

AlienVault Releases Intrusion Detection Systems (IDS) Best Practices

August 20, 2014Swati Khandelwal
Network security practitioners rely heavily on intrusion detection systems (IDS) to identify malicious activity on their networks by examining network traffic in real time. IDS are available in Network (NIDS) and Host (HIDS) forms, as well as for Wireless (WIDS). Host IDS is installed via an agent on the system you are monitoring and analyzes system behavior and configuration status. Network IDS inspects the traffic between hosts to find signatures of suspicious behavior and anomalies. Wireless IDS identifies rogue network access points, unauthorized login attempts, encryption-level in use, and other anomalous behavior. There are many options for open source IDS tools if your budget for buying new tools is tight. Asset inventory and vulnerability management go hand in hand with IDS. Knowing the role, function, and vulnerabilities of your assets will add valuable context to your investigations. AlienVault Unified Security Management (USM) includes IDS integrated with asset di
Hacker exploits Heartbleed bug to Hijack VPN Sessions

Hacker exploits Heartbleed bug to Hijack VPN Sessions

Cyber criminals have explored one more way to exploit Heartbleed OpenSSL bug against organisations to hijack multiple active web sessions conducted over a virtual private network connection. The consulting and incident response Mandiant investigated targeted attack against an unnamed organization and said the hackers have exploited the " Heartbleed " security vulnerability in OpenSSL running in the client's SSL VPN concentrator to remotely access active sessions of an organization's internal network. The incident is the result of attacks leveraging the OpenSSL Heartbleed vulnerabilities, which resides in the OpenSSL's heartbeat functionality, if enabled would return 64KB of random memory in plaintext to any client or server requesting for a connection. The vulnerability infected almost two-third of internet web servers, including the popular websites. Recently, there has been an arrest of a Canadian teen of stealing usernames, credentials, session IDs and other da

'The Washington Post' compromised 3rd time in the last 3 years

Security experts at Mandiant intelligence firm have discovered a new intrusion into the network of The Washington Post , it is the third time in the last three years. In time I'm writing it is still not clear the extension of the attack neither an estimation of the losses. Mandiant reported the incident to The Washington Post this week, confirming that exposed data include employees' credentials hash. " Hackers broke into The Washington Post's servers and gained access to employee user names and passwords, marking at least the third intrusion over the past three years, company officials said Wednesday. " a post of the news agency said. Early 2013 the New York Times has announced that during the previous months it was a victim of cyber espionage coordinated by Chinese hacker s, similar attacks was conducted against principal Americans news agencies. The hackers have tried to compromise the email account of journalists to steal sensitive information, they tried

Malware that transfers stolen data using Inaudible Audio signals

If you think that a computer which is not connected to a network, doesn't have any USB sticks attached to it and doesn't accept any kind of electronic connection requests are reasonably safe against hackers and from all the malware, then you are Wrong. Here we have something shocking update that Some German Scientists have developed a proof of concept Malware prototype, could allow a hacker to infect your computers and other digital devices just using  Inaudible Audio signals . The ability to bridge an air gap could be a potent infection vector. Just imagine, a cyber attack using high-frequency sound waves to infect machines, where stolen data also can be transferred back to attacker without a network connection, Sounds very terrifying ? When a few weeks ago, a security researcher Dragos Ruiu claimed malware dubbed badBIOS  allowed infected machines to communicate using sound waves alone, means that the devices are physically disconnected from any networks, including the inter
Importance of Logs and Log Management for IT Security

Importance of Logs and Log Management for IT Security

October 02, 2013Wang Wei
IT Security is the name of the game and no matter how big or small the size of your organization, you will always invest enough on securing certain aspects of your IT network. In many organizations, it starts with monitoring your network for vulnerabilities that may enter the network to access potentially sensitive information in the form of security attacks . For example, you may have firewalls as your first line of defense, followed by vulnerability management, intrusion detection and prevention systems, managing your network configurations and so on.  These are crucial because: Your routers can be easily breached without proper configuration and restrictions.  If a firewall isn't configured correctly, a hacker can easily spot a port that is accidentally left open and can gain access to the network.  Rogue access points, botnet malware and social engineering can make your wireless a porthole into your LAN. Why Logs? The very purpose of IT security is to be
Intrusion detected on two FreeBSD Project app dev servers

Intrusion detected on two FreeBSD Project app dev servers

The FreeBSD team has announced over the weekend that two machines within the FreeBSD.org cluster have been compromised and have been consequently pulled offline for analysis. Security team said on Saturday. " The affected machines were taken offline for analysis. Additionally, a large portion of the remaining infrastructure machines were also taken offline as a precaution, ". However it added that the intruder had sufficient access to modify third party packages, many of which are compiled and installed through FreeBSD's ports system. Audits have been performed to verify the infrastructure and source trees are clean and the suspect machines " are either being re installed  retired, or thoroughly audited before being brought back online ," the cluster administration team said . The FreeBSD Project was gearing up for the FreeBSD 9.1 release, however as it is unable to verify the integrity of the package set, that has been removed and will be rebuilt prior to th
