Capital One Financial Corp latest victim of Cyber Attack

Capital One Financial Corp. said it’s the latest target in a new round of coordinated cyber attacks aimed at disrupting the websites of major U.S. banks, and SunTrust Banks Inc. and Regions Financial Corp. said they expect to be next.

The so-called “Izz ad-Din al-Qassam Cyber Fighters” posted a specific timetable for its attack program on PasteBin.com, a website commonly used by hackers to brag about exploits. Izz ad-Din al-Qassam also threatened to pursue more cyber attacks next week and has long said it will not stop until the video is removed from the Internet.
American banks will reportedly face a massive cyberattack in coming weeks. A Russian-speaking hacker is organizing a massive trojan attack based around fraudulent wire transfers–and American banks appear to be at the center of the raid.
In the past, such attacks have sometimes caused websites to slow to a crawl or become inaccessible for some users; however, the impact cannot be gauged in advance. The same group has taken credit for attacks on Bank of America , J.P. Morgan Chase and the NYSE Euronext  in recent weeks.
Security professionals investigating the recent cyber attacks against the U.S. financial sector said last week that they discovered the tools at the heart of the attacks are more complex than previously thought and that a variant of the malware has been found in labs in Saudi Arabia. It’s not clear whether this means the malware used against U.S. banks came from Saudi Arabia or just ended up there coincidentally.

Splitting passwords up to increase security

Splitting passwords up could be the next big thing next to 2-factor authentication schemes which companies such as Google, Facebook or PayPal have offered as an opt-in service to their users. The two solutions use different angles to improve the protection of user account data from attackers. Where 2-factor authentication is entirely the user’s responsibility, splitting up passwords is entirely dependent on the webmaster and company running the server.

The idea itself is simple: instead of saving passwords in a single location, they are split up and saved in multiple locations. Attackers who attack the server infrastructure of a company therefore need to get into multiple servers instead of just one, and since it is possible to protect the servers in different ways, for instance by using different operating systems, firewalls, security scripts and personal, it reduces the possibility of a potential breach. The technique also protects the data from inside jobs, for instance when an admin downloads data from a database.

A new software by RSA brings the technology later this year on the market. RSA’s approach is the following. Passwords are broken into pieces during account creation, and then randomly saved to different servers. When a user logs in, the supplied password is split into encrypted strings, which are then sent to the password servers. The password is split into as many pieces as there are password servers, and one part of the string is randomly sent to each password server.

The user string is then combined with the stored password piece, and all the newly created strings are then compared to determine whether the password is correct or not. RSI claims that it is mathematically impossible to determine the password from an individual string or all strings combined.

1)      Before it is stored, the password is transformed with a random number. The random number is stored in one server (“red” server) and the transformed password in a different server (“blue” server). Compromising one server is not sufficient to compromise the password.

2)      At regular time intervals, a new random number is generated and both servers are updated with the new random number value, adding a time-based layer of protection:  Both servers must be compromised at the same time for the password to be compromised.

3)      When an application needs to verify a password, the claimed password transformed with a new random number is sent to the “blue” server while the random number is sent to the “red” server. Each server can execute a new transformation involving the stored data and validate whether the claimed password matches the stored password without exposing the legitimate password

RSA calls the approach distributed credential protection, which is a version of long known technique called threshold cryptography. What is new is that the technology will be made available to the general public.

Using multiple servers may be problematic from an availability point of view unless parts of the password are supplied to more servers than necessary so that fallback servers are available when a server goes down.

You can read about the announcement on the official RSA blog.

New data-theft attack technique can run across web

Researchers have detected a “new man-in-the-browser” (MITB) attack method that uses malware capable of stealing users bank or other sensitive information entered on websites.

As opposed to traditional MITB scams – where malware sitting on victims’ computers is used to monitor a list of targeted websites and then pounces when users visit those sites – this technique allows criminals to draw victims’ data from an unlimited pool of sites.

Computer servers at five Japanese universities hacked

An international group of hackers targeting five universities in Japan has leaked what appears to be personal information belonging to the institutions’ students and professors.

The group, which calls itself GhostShell, targeted the University of Tokyo, Kyoto University, Nagoya University, Tohoku University and Osaka City University.
