Wifiphisher – Fast Automated Phishing Attack Tool for WiFi Networks

wifiphisherWifiphisher is a security tool that mounts fast automated phishing attacks against WPA networks in order to obtain the secret passphrase. It is a social engineering attack that unlike other methods it does not include any brute forcing. It is an easy way for obtaining WPA credentials.

From the victim’s perspective, the attack makes use in three phases:

1] Victim is being deauthenticated from her access point: Wifiphisher continuously jams all of the target access point’s wifi devices within range by sending deauth packets to the client from the access point, to the access point from the client, and to the broadcast address as well.

2] Victim joins a rogue access point: Wifiphisher sniffs the area and copies the target access point’s settings. It then creates a rogue wireless access point that is modeled on the target. It also sets up a NAT/DHCP server and forwards the right ports. Consequently, because of the jamming, clients will start connecting to the rogue access point. After this phase, the victim is MiTMed.

3] Victim is being served a realistic router config-looking page: Wifiphisher employs a minimal web server that responds to HTTP & HTTPS requests. As soon as the victim requests a page from the Internet, wifiphisher will respond with a realistic fake page that asks for WPA password confirmation due to a router firmware upgrade.

Requirements:
― Kali Linux
― Two wireless network interfaces, one capable of injection.

Wifiphisher works on Kali Linux and is licensed under the MIT license.

Hackers Acquire Google Certificate, Could Hijack Gmail Accounts

Hackers have obtained a digital certificate good for any Google website from a Dutch certificate provider.

Google SSL Certificate

Criminals could use the certificate to conduct “man-in-the-middle” attacks targeting users of Gmail, Google’s search engine or any other service.

Attackers could poison DNS, present their site with the fake cert and bingo, they have the user’s credentials.

Man-in-the-middle attacks could also be launched via spam messages with links leading to a site posing as, say, the real Gmail. If recipients surfed to that link, their account login username and password could be hijacked.

Details of the certificate were posted on Pastebin last Saturday.

The SSL certificate is valid, and was issued by DigiNotar, a Dutch certificate authority, or CA.

It’s unclear whether the certificate was obtained because of a lack of oversight by DigiNotar or through a breach of the company’s certificate issuing website.

Given their ties to the government and financial sectors it’s extremely important to find out the scope of the breach as quickly as possible. The situation was reminiscent of a breach last March, when a hacker obtained certificates for some of the Web’s biggest sites, including Google and Gmail, Microsoft, Skype and Yahoo.

Then, Comodo said that nine certificates had been fraudulently issued after attackers used an account assigned to a company partner in southern Europe.

Initially, Comodo argued that Iran’s government may have been involved in the theft. Days later, however, a solo Iranian hacker claimed responsibility for stealing the SSL certificates.

Mallory – Transparent TCP and UDP Proxy

Mallory ProxyMallory is a transparent TCP and UDP proxy.
It can be used to get at those hard to intercept network streams, assess those tricky mobile web applications, or maybe just pull a prank on your friend.

In more technical terms, Mallory is an extensible TCP/UDP man in the middle proxy that is designed to be run as a gateway.

“Chat-in-the-Middle” Phishing Attack via Bogus Live-Chat Support

A new, unique type of phishing attack targeted against online banking customers was recently discovered by the RSA FraudAction Research Lab. RSA has coined this as a “Chat-in-the-Middle” phishing attack and it is first executed through routine means but then presents a more advanced layer of perpetrating online fraud. The phishing attack may dupe bank customers into entering their usernames and passwords into an ordinary phishing site but the addition of a bogus live chat support window can obtain even more credentials via a live chat session initiated by fraudsters.

During the live chat session, the fraudster behind the attack presents himself as a representative of the bank’s fraud department and attempts to dupe customers who are online into divulging sensitive information – such as answers to secret questions that are used for online customer authentication. This attack is currently targeting a single U.S.-based financial institution.

Upon detecting the attack RSA immediately informed the affected financial institution and commenced a standard phishing attack shut-down procedure through the RSA Anti-Fraud Command Center and its RSA FraudAction service. (RSA cannot identify this bank in order to protect its security and privacy.) The attack is hosted on a well-known fast flux network for “hire” from fraudster to fraudster, which hosts a wealth of malicious websites such as phishing attacks, Trojans infection points, mule recruitment websites, and more.
