The H-online: Google has closed several cross-site scripting (XSS) holes in its Gmail email service – which has more than 350 million active users – that could have allowed an attacker to inject a malicious client-side script into a victim’s system. Security researcher Nils Juenemann discovered the three different XSS vulnerabilities in Gmail and disclosed them to Google’s Security Team as part the company’s Vulnerability Reward Program, in which researchers are rewarded with up to $20,000 for reporting qualifying bugs in its web-based services. ...

The H-Online: Adobe has announced the release of an update for Flash Player on Windows, Mac, Linux, Android 3.x and 4.x, and within its own AIR runtime. The update addresses several critical vulnerabilities which involve memory corruption, stack overflows, integer overflows, security being bypassed, null dereferencing and binary planting (DLL hijacking). All, except the security bypass, could lead to code execution. ...

The H-Online: There have still been no official statements on the causes and extent of the recent password leaks at LinkedIn, eHarmony and Last.fm. A credible source is now reporting that the published 2.5 million Last.fm MD5 hashes, for example, are just the tip of a 17 million hash iceberg. That iceberg has reportedly been circulating since summer 2011.16.4 million of these – 95 per cent – have, the source claims, already been cracked, a claim which, for unsalted hashes, is entirely credible. ...

The H-Online: A list with several million passwords belonging to users of the music community site Last.fm has been posted on the internet. The site owners have posted a statement saying that the company is investigating the leak and that all users of the service should change their passwords immediately. This is the third major compromise of a popular web site’s passwords in as many days. ...

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. ...

Avira TechBlog Wrote: Microsoft released Security Advisory 2718704 which revokes some certificated which apparently were used to sign the trojan Flame__. In a blog post, Microsoft explains how they discovered that some components of the malware have been signed by certificates that allow software to appear as if it was produced by Microsoft. The certificates issued by the Terminal Services licensing certification authority, which are intended to only be used for license server verification, were also used to sign code and make it look like as if it was originated from Microsoft. ...

This is an old story back from September, 2011, but since recently I’ve seen users complaining about this, I want to share it again [Credit to NakedSecurity, SophoLabs]: You may have received an automated call from a user who claim to be from Skype or somewhere which says: Attention: this is an automated computer system alert.

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. ...

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. ...
