Hackers often find fascinating files in the most ordinary of places, one of those being FTP servers. Sometimes, luck will prevail, and anonymous logins will be enabled, meaning anyone can just log in. But more often than not, a valid username and password will be required. But there are several methods to brute-force FTP credentials and gain server access.
File Transfer Protocol is a network protocol used to transfer files. It uses a client-server model in which users can connect to a server using an FTP client. Authentication takes place with a username and password, typically transmitted in plaintext, but can also support anonymous logins if available.
To mitigate the problem of phishing sites impersonating a victim site by embedding its images (such as logos), several site owners have altered the images to send a message to the visitor that a site may be fraudulent. The image may be moved to a new filename and the original permanently replaced, or a server can detect that the image was not requested as part of normal browsing, and instead send a warning image.
Companies have also joined the effort to crack down on phishing. On March 31, 2005, Microsoft filed 117 federal lawsuits in the U.S. District Court for the Western District of Washington. The lawsuits accuse "John Doe" defendants of obtaining passwords and confidential information. March 2005 also saw a partnership between Microsoft and the Australian government teaching law enforcement officials how to combat various cyber crimes, including phishing. Microsoft announced a planned further 100 lawsuits outside the U.S. in March 2006, followed by the commencement, as of November 2006, of 129 lawsuits mixing criminal and civil actions. AOL reinforced its efforts against phishing in early 2006 with three lawsuits seeking a total of US$18 million under the 2005 amendments to the Virginia Computer Crimes Act, and Earthlink has joined in by helping to identify six men subsequently charged with phishing fraud in Connecticut.
Files: dump.pcapng, premaster.txtDescription: Capture and related keylog file of a openssl's s_client/s_server HTTP GET request over TLSv1.2 with 73 different cipher suites (generated using openssl-connect for Bug 9144 - Update TLS ciphers)
MyHeritage, a genealogical service website was compromised, affecting more than 92 million user accounts. The breach occurred in October 2017, but wasn't disclosed until June 2018. A security researcher discovered a file on a private server containing email addresses and encrypted passwords. The security team at MyHeritage confirmed that the content of the file affected the 92 million users, but found no evidence that the data was ever used by the attackers. MyHeritage earned praise for promptly investigating and disclosing details of the breach to the public.
Misconfiguration is when there is an error in system configuration. For example, if setup pages are enabled or a user uses default usernames and passwords, this can lead to breaches. With setup/app server configuration not disabled, the hacker can determine hidden flaws, and this provides them with extra information. Misconfigured devices and apps present an easy entry point for an attacker to exploit.
A brute force attack is easy to identify and investigate. You can detect them by looking into your Apache access log or Linux log files. The attack will leave a series of unsuccessful login attempts, as seen below:
For example, if a server were under attack frequently, several hundred user accounts could be locked-out constantly. Your server would be easy prey for denial-of-service. Be proactive to detect and stop DDoS attacks.
As stated above, implementing an account lockout after several unsuccessful login attempts is ineffective as it makes your server easy prey for denial-of-service attacks. However, if performed with progressive delays, this method becomes much more effective.
This Tomcat vulnerability allows a web-apps to reference an XML parser insteadof using the default Apache XML parser. The attacker must remove all existingweb-apps including those in server/webapps, then install a web-app with an XMLparser is stored in WEB-INF/lib. This will cause Tomcat to use the new XMLparser to process all web.xml, context.xml and tld files of other webapps. Ifthat non-standard XML parser is replaced with a malicious one, the content ofthe victim web app XML can be disclosed, the resulting JSP could be corrupted(if it compiled at all) or possibly even weaponized for further attacks.
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does notproperly restrict processing of ChangeCipherSpec messages during the SSL/TLShandshake. A ChangeCipherSpec message tells the client/server to switch fromunencrypted to encrypted communication. If a ChangeCipherSpec message is sent bythe attacker after the connection is initiated but before the master secret hasbeen generated, OpenSSL will generate the keys for the handshake with an emptymaster secret. This zero-length master key allows an attacker to crack theencryption and consequently obtain sensitive information and/or modify SSL/TLStraffic. Note that an attacker requires a man-in-the-middle position with theclient user in order to exploit this attack.
Packed with features, these apps make it easy-peasy to transform your thoughts and ideas into digital form, so you won't have to worry about losing them ever again. Some more advanced apps even support various formats besides text, such as visuals (images and videos), audio records, and offer sharing capabilities.
Box is an advanced notepad app designed to help teams with taking notes in real-time. Whether it be sharing notes with partners or brainstorming with your workfellows, Box boosts team productivity and makes it easy to take notes, share ideas, plan projects, write newsletters, organize reviews, and get everyone on the same page regardless of the type of device you own.
By the way, Paper is launched by We Transfer, an app built for file sharing. This integration makes it easy to share your notes and works of art with whoever needs to see them. The only downside to this app is the fact it is available only for iPhone, iPad, iPod touch, and Mac users.
Amazon EFS is a file storage service for use with Amazon compute (EC2, containers, serverless) and on-premises servers. Amazon EFS provides a file system interface, file system access semantics (such as strong consistency and file locking), and concurrently accessible storage for up to thousands of Amazon EC2 instances.
If we determine the real IP address of the server and add an entry to our hosts' file, we can bypass the firewall and go directly to the webserver hosting the site. This is significant if the site is not well maintained and relying on the protection of the firewall. For example, a vulnerable plugin may be present but being blocked by the firewall. We bypass the firewall, exploit the vulnerable plugin and the server.
Mind that it is always better to host images for email signatures on your own servers. If you do not own a server, your best bet is to use an image hosting service. The article below presents how to get a direct link in some popular image and file hosting services. As you will see, it requires more than just right-clicking the image and choosing copy image address. Click the name of an image hosting service below to learn how to get a direct image URL:
It happens reliably when I create a .zip on a windows server, copy the file down to my mac via RDC (mapped drive). It only happens with one particular server, otherwise I use this method routinely with other win servers with no problems. The file is not corrupt as far as i can tell, or incompletely copied, some sort of bug or mismatch created by this sequence of events is responsible. 2b1af7f3a8
