Trend has done an analysis of #OpIsrael attacks on April 7. It notes that on that particular day, traffic to one particular website, normally around 90% Israeli, became 90% international due to the botnet DDoS attacks.
This increase in non-Israeli traffic was well distributed, with users from 27 countries (beside Israel itself) accessing the target site.
This is factual and we can take it at face value from a company like Trend. The next comments, however, start with fact but end in interpretation:
[fact] Examining the IP addresses that had accessed the target site, we noticed that some of these were known to be parts of various botnets under the control of cybercriminals. In addition, further investigation revealed that these IP addresses had been previously identified as victims of other attacks like FAKEAV, ransomware, and exploit kits.
[opinion] These findings highlight how major DDoS attacks are, at least in part, not just carried out by hacker groups like Anonymous but by cybercriminals as well. These attacks are not nearly as “harmless” as some would think.
The interpretation is that because a particular PC is known to be infected with a bot, participation in the DDoS attack against Israel was necessarily under the direction of the botherder criminal. But an alternative interpretation could be that the PC owner, entirely independently, decided to take part in the protest. (This is unlikely given the need to hide the source IP during such a protest.) Another possibility, however, could be that an activist protester, not otherwise a criminal, could have hired a botnet from a criminal, not otherwise an activist.
My point is that the final comment (“major DDoS attacks are, at least in part, not just carried out by hacker groups like Anonymous but by cybercriminals as well”) is a non-sequitur from the preceding argument. Trend may be right; but should not be making such a bald statement without further ‘proof’.
It highlights a danger we all face as we shift our news intake from traditional newspapers to blogs: the automatic acceptance of an opinion as fact. Blogs, for their part, should draw a distinction between fact and opinion – and the conclusion of this particular blog should be clearly labelled ‘opinion’.
Before I say anything else, let me just say that I really, really like Sophos; and I really, really like NakedSecurity; and I really, really like Graham Cluley. This is really, really just a comment on how the internet has upset the status quo rather than a criticism of any of the above.
Purely coincidentally I was talking to a fellow freelancer who, like me, is old enough to remember the golden, halcyon days of freelancing back in the mists of the last century. The internet has destroyed all that, along with the majority of magazines
I used to write for for whom I used to write.
“Today,” I said, “company blogs have replaced independent magazines. Just take NakedSecurity, which competes head on with the security magazines in terms of content.”
I stand by that. It’s a great blog and a great read written by experts in their subject. But the one thing it isn’t is ‘independent’.
Consider one of today’s news items: Microsoft and Symantec jointly took down the Bamital botnet (my news story is on Infosecurity Mag here). The problem is that Symantec, a direct competitor of Sophos, gets hardly a look-in on the Sophos blog – which is headlined: Bamital botnet dismantled, as Microsoft seizes control of malware servers.
In fact, you wouldn’t think that Symantec was involved in the actual takedown at all judging from the Sophos account – despite the fact that it published an excellent and detailed analysis of Bamital today.
Coincidence? Possibly; but I doubt it. The problem is that NakedSecurity is so good and so popular that it is often taken as news. It isn’t. It’s a marketing machine for Sophos – and readers should always bear in mind (not just for NakedSecurity, but for all of the company blogs that are replacing the magazines) that the one thing you cannot get from a company blog is independent news.
Apple, it keeps telling us, is on top of security. Well, I used to give it the benefit of the doubt on that; but now I’m not so sure. What worries me is not the existence of a massive Mac botnet (Windows suffers from far more), nor even Apple’s response to the finder of the botnet, Russian firm Dr Web. “We’ve given them all the data we have,” said Dr Web’s chief executive Boris Sharov. Apple’s reply? Zilch – but that’s just arrogance, not really anything to worry about, just something we have to accommodate.
It’s the one thing that Apple actually did do that worries me.
The botnet was discovered by Russian firm Dr Web. Not exactly a big name in security, but a good one nevertheless. The company set up three sinkhole servers to help monitor the botnet, estimate its size – and perhaps take it down. Apple’s one actual response? It contacted Russian Web registrar Reggi.ru and asked for one of the servers to be shut down since it was engaged in malicious activity. It wasn’t – it was one of Dr Web’s sinkholes.
Dr Web’s CEO, Boris Sharov, thinks this was an honest mistake by Apple. I suspect it was a dishonest mistake. I suspect it was more to do with Apple attempting to maintain its carefully constructed facade of invulnerability. I suspect that if it had been one of the better known anti-malware companies that had discovered this 600,000 strong Mac botnet Apple would have reacted differently. Instead they thought they could keep quiet, try to shut down the botnet by taking down a C&C server and nobody would be any the wiser.
Instead the company has simply shown itself to be a child in an adult’s playground. Poor show, Apple.

Steve Ranger at Silicon.com published an interesting (Chinese interesting, that is) article on Tuesday (6 Dec): Want to stop botnets overnight? Ban infected PCs from the net. The title is unfortunate, because I think even Steve knows that banning (known) infected PCs wouldn’t stop botnets anytime soon, nevermind overnight.
The time has come to ignore the howls of protest, the cries of ‘I didn’t know!’ and ‘It wasn’t me!’, and to decide that if a PC is infected with viruses or has become part of a botnet, it should no longer be allowed access to the internet…
ISPs can easily spot if a device is part of a botnet, or is riddled with viruses… [No]
Taking these rogue PCs off the net will save the rest of us time, money and hassle. It sends the message that accessing the web is a privilege to be earned and not a right to be unthinkinhgly [sic] abused… [It is now considered a ‘human right’]
…I’d wager the spam and botnet problem would disappear overnight if such measures were put in place. [No they won’t]
Want to stop botnets overnight? Ban infected PCs from the net.
Oh, where do I begin?
Rather than that, I turned to Kaspersky’s David Emm for an opinion. “On the face of it,” he said, “this seems very reasonable – but it’s not as straightforward as it sounds.
“A few years ago,” he continued, “the House of Lords Science and Technology Committee, in its report ‘Personal Internet Security, suggested that we ought to review the ‘neutral carrier’ status of ISPs and make them assume some responsibility for what goes through their network. If we were to do so, however, it would not be very easy to enforce. You would have to demonstrate that an ISP knowingly transmitted malware across its network.”
That word ‘knowingly’ has wider ramifications. What do we do with the user who has the latest security, but gets caught by an unknown 0-day virus? Warn him/her? And then it happens again, and once again. Cut him off at the connectors? It’s not the user’s fault – he or she was as well-protected as possible. Is it the security industry’s fault? Hardly.
“And anyway, continued David, “if we were to introduce such measures, there might be a danger that consumers would wash their hands of the problem and see it as the ISP’s responsibility.” Well, you could make a better case for it being the ‘fault’ of the ISP than the user; so what do we do? Shut down the ISP?
“The truth is,” says David, “that we all have to assume responsibility when we go online.”
Singling out the user is not the way to go.
