LinkedIn passwords in circulation

Published: June 6, 2012 Reading time: 2 min

H-Online: Internet forums are currently circulating a list containing over six million password hashes which allegedly originate from LinkedIn. The passwords are being cracked collaboratively with about 300,000 passwords already published as plaintext. The list contains pure SHA1 hashes with no name or email addresses. If decrypted, the passwords will not easily give access to an appropriate account. However, it is probable that the person who captured the hashes also has the corresponding email addresses. In an initial sampling, The H‘s associates at heise Security didn’t find any known LinkedIn passwords in the list, but with over 160 million members that doesn’t mean a lot. The already cracked passwords often contain “linked” or even “linkedin” in the form, for example, of “lawrencelinkedin”. This suggests that the passwords actually come from the LinkedIn social network. However, this has not yet been confirmed. ...

On Stuxnet, Duqu and Flame

Published: June 3, 2012 Reading time: 2 min

F-Secure wrote: When we went digging through our archive for related samples of malware, we were surprised to find that we already had samples of Flame, dating back to 2010 and 2011, that we were unaware we possessed. They had come through automated reporting mechanisms, but had never been flagged by the system as something we should examine closely. Researchers at other antivirus firms have found evidence that they received samples of the malware even earlier than this, indicating that the malware was older than 2010. ...

FAQ: Flame, the "super spy"

Published: May 31, 2012 Reading time: 4 min

Copied from H-Online: Source The spyware worm Flame is being billed as a “deadly cyber weapon”, but a calmer analysis reveals it to be a tool by professionals for professionals that doesn’t actually have that many new features compared to, say, the widespread online-banking trojan Zeus. What is Flame? Flame is the code name for a spyware program that is built to be very modular and which is also known as Flamer and sKyWIper. Flame was just recently discovered, and it will be some time before all of its components are analyzed. Anti-virus software companies estimate that Flame has infected about 1,000 computers, mostly in the Middle East. ...

Painting a Picture of W32.Flamer

Published: May 31, 2012 Reading time: 1 min

Symantec Connect: The number of different components in W32.Flamer is difficult to grasp. The threat is a well designed platform including, among other things, a Web server, a database server, and secure shell communications. It includes a scripting interpreter which allows the attackers to easily deploy updated functionality through various scripts. These scripts are split up into ‘apps’ and the attackers even appear to have something equivalent to an ‘app store’ from where they can retrieve new apps containing malicious functionality. ...

Google's reCAPTCHA briefly cracked

Published: May 30, 2012 Reading time: 2 min

H-Online: Hackers developed a script which was able to crack Google’s reCAPTCHA system with a success rate of better than 99 per cent. They presented the results of their research at the LayerOne security conference in Los Angeles last weekend; however, their demonstration was somewhat frustrated as, just an hour before the presentation, Google made improvements to its CAPTCHA system. Of the various CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) systems, Google’s reCAPTCHA is considered to be one of the most reliable for differentiating man from machine. By requiring users to enter visually distorted alphanumeric sequences, web service providers can, for example, ensure that their registration forms are not flooded by spam bots. Rather than trying to analyze these distorted characters, the script, code-named “Stiltwalker”, analyzed the audio version of the CAPTCHAs, which Google provides for individuals who are visually impaired. ...

H-Online: UK regulator PhonepayPlus (fomerly known ICSTIS) has imposed a fine of £50,000 on a payment provider used for an Android malware-based fraud and forced it to reimburse customers’ losses.
