IE in fresh security drama

Three bugs, two critical


IE is subject to a trio of unpatched vulnerabilities, security firm Secunia warned yesterday. It warns that two of the three unfixed security bugs are on the "critical" list.

These "deadly duo" could be exploited in tandem to bypass security features in Windows XP SP2 and trick users into downloading malicious files. Flaws in the function used to warn users that they are downloading a potentially executable file and a separate bug that can be used to spoof the file extension in the "Save HTML Document" dialog give attackers the opportunity to disguise malicious executable files as innocuous HTML documents.

The vulnerabilities, published by hacker cyber flash, have been confirmed on a fully patched system with IE 6.0 and Windows XP SP2. Secunia advises IE users to Disable Active Scripting support and the "Hide extension for known file types" option as workarounds in advance of a patch from Microsoft. Secunia describes the flaws as "moderately critical".

A third - less serious - IE bug that could be used to overwrite cookies from trusted site has also been discovered. The vuln has been reported in Internet Explorer 6.0 SP1 on Microsoft Windows XP SP1. But Windows XP SP2 is reportedly immune to the exploit, which in any case only works if a trusted site handles cookies and authentication badly. ®

    Choice is the word for Jamf's Dean Hager

    Interview As Apple's devices continue to find favour with enterprise users, the fortress that is Windows appears to be under attack in the corporate world.

    Speaking to The Register as the Jamf Nation User Conference wound down, the software firm's CEO, Dean Hager, is - unsurprisingly - ebullient when it comes to the prospects for Apple gear in the world of suits.

    Jamf specialises in device management and authentication, and has long been associated with managing Apple hardware in business and education environments. In recent years it has begun connecting its products with services such as Microsoft's Azure Active Directory as administrators face up to a hybrid working future.

  • There’s a wave of ransomware coming down the pipeline. What can you do about it?

    AI can help. Here’s how…

    Sponsored The Colonial Pipeline attack earlier this year showed just how devastating a ransomware attack is when it is targeted at critical infrastructure.

    It also illustrated how traditional security techniques are increasingly struggling to keep pace with determined cyber attackers, whether their aim is exfiltrating data, extorting organisations, or simply causing chaos. Or, indeed an unpleasant combination of all three.

    So, what are your options? More people looking for more flaws isn’t going to be enough – there simply aren’t enough skilled people, there are too many bugs, and there are way too many attackers. So, it’s clear that smart cyber defenders need to be supplemented by even smarter technology incorporating AI. You can learn what this looks like by checking out this upcoming Regcast, “Securing Critical Infrastructure from Cyber-attack” on October 28 at 5pm.

  • Ransomware criminals have feelings too: BlackMatter abuse caused crims to shut down negotiation portal

    Or so says infsec outfit Emsisoft

    Hurling online abuse at ransomware gangs may have contributed to a hardline policy of dumping victims' data online, according to counter-ransomware company Emsisoft.

    Earlier this month, the Conti ransomware gang declared it would publish victims' data and break off ransom negotiations if anyone other than "respected journalist and researcher personalities" [sic] dared publish snippets of ransomware negotiations, amid a general hardening of attitudes among ransomware gangs.

    Typically these conversation snippets make it into the public domain because curious people log into ransomware negotiation portals hosted by the criminals. The BlackMatter (aka DarkSide) gang's portal credentials (detailed in a ransom note) became exposed to the wider world, however, and the resulting wave of furious abuse hurled at the crims prompted them to pull up the virtual drawbridge.
