It’s nice when ransomware gangs have their bitcoin stolen, malware servers shut down, or are otherwise forced to disband. We hang on to these occasional victories because history tells us that most ransomware moneymaking collectives don’t go away so much as reinvent themselves under a new name, with new rules, targets and weaponry. Indeed, some of the most destructive and costly ransomware groups are now in their third incarnation over as many years.
Reinvention is a basic survival skill in the cybercrime business. Among the oldest tricks in the book is to fake one’s demise or retirement and invent a new identity. A key goal of such subterfuge is to throw investigators off the scent or to temporarily direct their attention elsewhere.
Cybercriminal syndicates also perform similar disappearing acts whenever it suits them. These organizational reboots are an opportunity for ransomware program leaders to set new ground rules for their members — such as which types of victims aren’t allowed (e.g., hospitals, governments, critical infrastructure), or how much of a ransom payment an affiliate should expect for bringing the group access to a new victim network.
Every time there is another data breach, we are asked to change our password at the breached entity. But the reality is that in most cases by the time the victim organization discloses an incident publicly the information has already been harvested many times over by profit-seeking cybercriminals. Here’s a closer look at what typically transpires in the weeks or months before an organization notifies its users about a breached database.
Our continued reliance on passwords for authentication has contributed to one toxic data spill or hack after another. One might even say passwords are the fossil fuels powering most IT modernization: They’re ubiquitous because they are cheap and easy to use, but that means they also come with significant trade-offs — such as polluting the Internet with weaponized data when they’re leaked or stolen en masse.
Browse the comments on virtually any story about a ransomware attack and you will almost surely encounter the view that the victim organization could have avoided paying their extortionists if only they’d had proper data backups. But the ugly truth is there are many non-obvious reasons why victims end up paying even when they have done nearly everything right from a data backup perspective.
Some of the world’s top tech firms are backing a new industry task force focused on disrupting cybercriminal ransomware gangs by limiting their ability to get paid, and targeting the individuals and finances of the organized thieves behind these crimes.
Some of the top ransomware gangs are deploying a new pressure tactic to push more victim organizations into paying an extortion demand: Emailing the victim’s customers and partners directly, warning that their data will be leaked to the dark web unless they can convince the victim firm to pay up.
It’s bad enough that many ransomware gangs now have blogs where they publish data stolen from companies that refuse to make an extortion payment. Now, one crime group has started using hacked Facebook accounts to run ads publicly pressuring their ransomware victims into paying up.
Companies hit by ransomware often face a dual threat: Even if they avoid paying the ransom and can restore things from scratch, about half the time the attackers also threaten to release sensitive stolen data unless the victim pays for a promise to have the data deleted. Leaving aside the notion that victims might have any real expectation the attackers will actually destroy the stolen data, new research suggests a fair number of victims who do pay up may see some or all of the stolen data published anyway.
In late May, KrebsOnSecurity alerted numerous officials in Florence, Ala. that their information technology systems had been infiltrated by hackers who specialize in deploying ransomware. Nevertheless, on Friday, June 5, the intruders sprang their attack, deploying ransomware and demanding nearly $300,000 worth of bitcoin. City officials now say they plan to pay the ransom demand, in hopes of keeping the personal data of their citizens off of the Internet.
Diebold Nixdorf, a major provider of automatic teller machines (ATMs) and payment technology to banks and retailers, recently suffered a ransomware attack that disrupted some operations. The company says the hackers never touched its ATMs or customer networks, and that the intrusion only affected its corporate network.
Ransomware — malicious software that encrypts the victim’s files and holds them hostage unless and until the victim pays a ransom in Bitcoin — has emerged as a potent and increasingly common threat online. But many Internet users are unaware that ransomware also can just as easily seize control over files stored on cloud services.
