Slashdot Mirror

Long-time Slashdot reader williamyf was the first to share news of "a wormable bug [that] has remained undetected for seven years in Samba verions 3.5.0 onwards." Ars Technica reports: Researchers with security firm Rapid7...said they detected 110,000 devices exposed on the internet that appeared to run vulnerable versions of Samba. 92,500 of them appeared to run unsupported versions of Samba for which no patch was available... Those who are unable to patch immediately can work around the vulnerability by adding the line nt pipe support = no to their Samba configuration file and restart the network's SMB daemon. The change will prevent clients from fully accessing some network computers and may disable some expected functions for connected Windows machines.
The U.S. Department of Homeland Security's CERT group issued an anouncement urging sys-admins to update their systems, though SC Magazine cites a security researcher arguing this attack surface is much smaller than that of the Wannacry ransomware, partly because Samba is just "not as common as Windows architectures." But the original submission also points out that while the patch came in fast, "the 'Many eyes' took seven years to 'make the bug shallow'."

An anonymous reader writes with an alert for anyone who uses the WhatsApp Web application. Check Point researcher Kasif Dekel, according to NetSecurity.Org, has discovered that "to exploit the vulnerability, an attacker simply needs to send a WhatsApp user a seemingly innocent vCard contact card, containing malicious code." When this card is opened from within the app, the executable it contains is run, "further compromising computers by distributing malware including ransomware, bots, remote access tools, and other types of malicious code." Not all users need to panic about this vulnerability, though: the company has rolled out a fix, contained in all versions of WhatsApp Web after v0.1.4481. But with an estimated 200 million users of the web-based version, many users aren't yet using the updated version.

Hugh Pickens writes "Mikko Hypponen, Chief Research Officer of software security company F-Secure, writes that when his company heard about Flame, they went digging through their archive for related samples of malware and were surprised to find that they already had samples of Flame, dating back to 2010 and 2011, that they were unaware they possessed. 'What this means is that all of us had missed detecting this malware for two years, or more. That's a spectacular failure for our company, and for the antivirus industry in general.' Why weren't Flame, Stuxnet, and Duqu detected earlier? The answer isn't encouraging for the future of cyberwar. All three were most likely developed by a Western intelligence agency as part of covert operations that weren't meant to be discovered and the fact that the malware evaded detection proves how well the attackers did their job. In the case of Stuxnet and DuQu, they used digitally signed components to make their malware appear to be trustworthy applications and instead of trying to protect their code with custom packers and obfuscation engines — which might have drawn suspicion to them — they hid in plain sight. In the case of Flame, the attackers used SQLite, SSH, SSL and LUA libraries that made the code look more like a business database system than a piece of malware. 'The truth is, consumer-grade antivirus products can't protect against targeted malware created by well-resourced nation-states with bulging budgets,' writes Hypponen, adding that it's highly likely there are other similar attacks already underway that we haven't detected yet because simply put, attacks like these work. 'Flame was a failure for the antivirus industry. We really should have been able to do better. But we didn't. We were out of our league, in our own game.'"

But today Britain's Lottery Fund is set to step in with a grant to rescue the ailing heritage site. (There was an earlier story on ZDNet.)"
