Half of Ransomware Victims Didn't Recover Their Data After Paying the Ransom (bleepingcomputer.com) 58

Posted by msmash from the tough-luck dept.
An anonymous reader shares a report: A massive survey of nearly 1,200 IT security practitioners and decision makers across 17 countries reveals that half the people who fell victim to ransomware infections last year were able to recover their files after paying the ransom demand. The survey, carried out by research and marketing firm CyberEdge Group, reveals that paying the ransom demand, even if for desperate reasons, does not guarantee that victims will regain access to their files. Timely backups are still the most efficient defense against possible ransomware infections, as it allows easy recovery. The survey reveals that 55% of all responders suffered a ransomware infection in 2017, compared to the previous year's study, when 61% experienced similar incidents. Of all the victims who suffered ransomware infections, CyberEdge discovered that 61.3% opted not to pay the ransom at all. Some lost files for good (8%), while the rest (53.3%) managed to recover files, either from backups or by using ransomware decrypter applications. Of the 38.7% who opted to pay the ransom, a little less than half (19.1%) recovered their files using the tools provided by the ransomware authors.

      Ransomware criminals shouldn't shit where they drink. By failing to unlock the files, they decrease the chance future victims will be willing to pay. Unfortunately for the criminals there are any number of other criminals out there who don't follow this simple rule. They don't unlock because they don't care, they're only in it for the short term, or they failed to implement unique wallets per victim to verify who's paid them and who's only claiming to have done so.

        Let's all be happy about it. It keeps more people from paying. I've always wondered if these non-successful recoveries were due to black hats trying to teach the public at large to stop paying ransoms. It also helps spread the message that there is no substitute for backups.

          • Sounds more like they're helping another TLA cover the tracks of domestic spying disguised as ransomware. That sounds awfully suspicious when you cherry pick the phrases like that - and I'm not even that paranoid.

          I see no reason to think that, it's just criminal assholes saying "fuck it, we've got the part which fucks up the computer and makes them pay, why the fuck would we care about what happens to your data?" Why spend time making a complete solution? Get your money and leave.

      • Even if there is almost zero percent change that the ransomware authors can/will unlock files, people will still pay. Mainly because they have a lottery's chance of getting their files back versus 0% if they don't.

          I paid the full ransom. At least, that's what I'll say if anyone asks why I bought and spent Bitcoin. Google tells me that Overstock.com and a couple of others take Bitcoin now, but is anyone actually buying legitimate goods with it? The overhead's high and the latency is a nuisance if you aren't prepared ahead of shopping. It's useful for contraband, ransoms, and blind speculative investing, but I'm not sure why I'd use it for a book, a TV, or a sandwich.

          Yep, the amount of money asked by ransomware author's is priced with risk/reward in mind. The less confidence people have in recovering their the lower the price goes.

          • The less confidence people have in recovering their the lower the price goes.

            Not really, the price is based only on what those who do comply can pay. The amount of money 419 scammers ask for in their emails doesn't go up or down according to number of compliant victims either.

        I tend to doubt that. People who have no other recourse to recover their precious data will pay. Even if there's only a slight chance of success.

      Smart criminals give you what you paid for.
      It is a business, and the victims are like customers. All the rules that apply to legitimate companies apply too. They want your money, and for that, they need to make it clear that the best solution in order to recover your files is to pay the ransom. If people start thinking that paying is useless anyways, it will hurt their bottom line in the long run.
      From what I understood, mafias are very reliable. It you pay for "protection", they really protect you. Ineffect

    • Macrium Reflect, EaseUS ToDo Backup, and Paragon Backup and Recovery all have free versions which support incremental or differential backups. Those will only backup the changes from previous backup(s), so will cut down backup time significantly. I still recommend a full backup about once a month.

      The important (and difficult) thing is that your backup needs to be offline. If you try to use an always-online device like a NAS or permanently attached external drive as a backup, the ransomware will just e

      • If you do backups, look at the 3-2-1 methodology. Three copies, two on different media, one offsite.

        For example: CrashPlan and Veeam to a NAS. CrashPlan takes care of offsite documents, Veeam allows you to restore locally. A lot of NAS models also can back themselves up as well as keep snapshots, so a share nailed by ransomware can be rolled back quickly, or restored from somewhere.

      I would do two things:

      1. Isolate every device including every PC on the LAN using a real router instead of a switch. Then every device can see the internet unimpeded but all traffic between devices is controlled by the firewall which be default can block everything. Most routers only have one LAN port no matter how many switched ports are connected to it so the cheapest way to implement this is some PC hardware with multiple LAN ports or perhaps better, using a router which supports VLANs and attaching a
