What next?The burning question now, of course, is, “What do the crooks do next?”The world’s first-ever ransomware attack, the AIDS Information Trojan of 1989, failed for two fortunate reasons. Victims span a range of worldwide locations with most in the United States, Germany and Canada, and others in Australia, the UK and other regions.Independence Day: REvil uses supply chain exploit to attack hundreds of businessesWe’ve also published IoCs ( indicators of compromise) on our GitHub page if you want to use threat-hunting tools to look for evidence of an attack on your own network, as well as the names Sophos products will report in logfiles when detecting and blocking the various components used in this attack. We expect the full scope of victim organisations to be higher than what’s being reported by any individual security company.
Kaseya Password Into EveryCentral paymentEven though many modern ransomware Trojans use a different session key for every file they scramble, let alone for every computer, contemporary ransomware is geared towards bulk payments.The idea is that instead of hitting as many computers as they can on your network and asking for a few hundred dollars to decrypt each one, the crooks offer to sell each victim a “bulk decryptor” that can unscramble some, many or all of the computers on their network.This is the same sort of technique that legitimate encryption software uses to provide a controlled way for specially appointed staff to recover data off employees’ computers if they forget their password, or leave the company in a huff with their data still locked up.This isn’t the same as an encryption backdoor that could let anyone with insider knowledge about the algorithm decrypt the data. Even if you intercept all the network traffic at the start of the HTTPS connection, public-key cryptography means that you can’t extract the so-called session key needed to decrypt the rest of the HTTPS connection either.If you get attacked and pay the extortion money, there’s no point in sharing your unlocking key with anyone else, even if they’ve been hit by exactly the same ransomware, because each decryption key is unique.Programming blunders by some ransomware cybercrooks have occasionally made it possible to recover without paying in some attacks, but gangs like REvil, the criminal gang behind the Kaseya attack, generally get the coding correct.If you don’t have a backup then paying the blackmail money for the decryption key is about your only chance of recovering your scrambled data. Public-key cryptography allows your browser and the web server at the other end to agree on a one-time data scrambling key, used with traditional symmetric encryption (where the same key both locks and unlocks the data) to protect the current session. He hard-coded the same decryption password into every copy of the malware, so that once the malicious code has been reverse-engineered (including by Sophos co-founder Dr Jan Hruska, who published a detailed public analysis of how it worked) and the key extracted, there was no need for anyone to pay up.It wasn’t until about 2013 that contemporary cybercriminals “solved” these ransomware payment-and-recovery problems.Cryptocurrency made pseudoanonymous international payments possible, so the crooks could collect their blackmail demands entirely online, without involving traditional financial institutions who could freeze or reverse illegal transactions.And public-key cryptography, where you use one key (the public key) to lock up data, but need a different key (the private key) to unlock it again, made it possible to have a unique decryption key for each network, or each computer, or even for each file.This is the same principle that’s used for good when you visit an HTTPS website. The creator of the ransomware made a cryptographic blunder.Universal decryptorsEarly ransomware attacks typically relied on squeezing hundreds of thousands of people to pay about $300 each to buy back the decryption keys for their own (but no one else’s) computer.Make no mistake, crooks such as the CryptoLocker gang raked in millions of dollars, maybe even hundreds of millions of dollars, this way:1 in 30 have been hit by CryptoLocker and 40% pay the ransom, says studyIf you had 10 computers on your network all scrambled at the same time, that was just bad luck: to recover them all meant paying 10 separate $300 blackmail demands.But later attackers took a hybrid approach.The SamSam crew, for example, notoriously hit one network at a time, and callously offered “deals” on decryption.The price shot up to $8000 per computer, so if you felt that you could recover your business by decrypting just two or three of your most critical laptops or servers, you didn’t have to pay for all of them, but you couldn’t get away with just $300 each, either.But for a one-off fee that usually came out at $50,000, the SamSam crooks would give you a universal decryptor (universal to your network, at least) that was pitched as a sort of “all you can eat buffet.”In fact, in a fit of “goodwill”, they’d even let you try paying the $8000 fee for individual computers, to see if you could recover enough of your business to get away without paying $50,000 in total.Sadly, many victims found that the one-by-one approach just didn’t work out for them, at which point the SamSam crooks would “graciously” allow them to top up their payments to the $50,000 mark.Once the crooks had received the all-you-can-eat fee of $50,000, they’d give you a “software upgrade” to the universal decryptor that would work on all of your computers, not just specific ones you had chosen in advance:Iranian hackers charged in the US for SamSam ransomware attacksMore recently, most mainstream ransomware crooks have discontinued the “individual decryptor” option and will only negotiate to sell universal decryptors – and as we all know, they aren’t asking for $50,000 any more.Extortion demands often reach several million dollars, with recent victims Colonial Pipeline allegedly coughing up $4.4 million (ironically for a decryptor that was so slow as to be worthless), and meat packing company JBS supposedly paying out a mammoth $11 million in blackmail money.The REvil gang have apparently now decided that they are going to offer what you might call a universal universal decryptor that will not only unscramble all the computers on your network, but also all the computers on the networks of everyone else affected by what we shall probably be calling the Independence Day attack for many years to come.This time, the ueberuniversal decryptor isn’t $50,000, or $4,400,000, or even $11,000,000.The crooks are calmly demanding $70,000,000:On Friday () we launched an attack on. This provides additional privacy control that helps to protect both the user and the company. These decryption keys may be split up between more than one person, for example so that an individual computer can be unscrambled either by the user acting alone in day-to-day use, or by the IT manager and HR manager acting together in an emergency. This means that there may be multiple decryption keys that can decrypt the master key that in turn decrypts the actual data. Instead, a random “master encryption key” is generated to secure the data, and that key is re-enrcypted multiple times, using different passwords or public keys. Acdsee 18 license keyWhat to do?This audacious demand raises many difficult questions.Many governments and most law enforcement experts vigorously encourage victims not to pay up.Even though it seems that at least some of the money goes on fancy cars, we we know for sure that at least some of the funds from today’s attacks are directly used to fund tomorrow’s:REvil ransomware crew dangles $1,000,000 cybercrime carrotSome governments are even seriously considering making ransomware payments illegal as way of breaking the cycle of attacks. If you are interested in such deal – contact is using victims “readme” file instructions. If anyone want to negotiate about universal decryptor – our price is and we will publish publicly decrypto that decrypts all files of all victims, so everyone will be able to recover from attack in less that an hour.
