In a disturbing trend that bodes ill for everyone, multiple US healthcare institutions have been victimized this past month by highly effective ransomware attacks. In each instance, the malware infection has significantly disrupted operations and, in some cases, forced administrators to actually pay out thousands of dollars in ransoms to regain control of their data and IT systems. In the case of the Hollywood Presbyterian attack, the hackers initially demanded $3.6 million in bitcoin to release the data and systems their malware had encrypted, but settled for $17k. More hospitals in California, Kentucky and Maryland have also been hit and crippled by ransomware attacks, in some cases paying the ransom to regain control of their IT systems, and in other cases recovering systems and data through established data backup platforms and security protocols. And just to keep things interesting, toy-maker Mattel was also defrauded out of $3 million after falling victim to a carefully-planned an well-executed email scheme.

What this means for you:

Though some of the hospital attacks mentioned above are thought to have come from a documented server exploit known to exist in healthcare software platforms, analysts are reporting a surge in emails carrying viral payloads including new, highly-effective variants of ransomware, probably because of the highly-publicized ransom payment made by Hollywood Presbyterian. The harsh reality of this worrying trend is this: it costs criminals virtually nothing to start malware campaigns that are resulting in hundreds of millions in damages to organizations around the world, and it’s netting those same criminals an equivalent amount of money paid by desparate victims. Despite spending millions on security, businesses and individuals around the world still fall victim to this ploy because of the humble email. Previously I had written about ways to spot fake emails (and you can still spot them if you look hard enough), but given how many emails we receive, and how clever attackers are becoming, it’s only a matter of time before any of us get duped and it’s already too late after that second mouse-click. Or is it? Though the ransomware attacks managed to disrupt operations at the hospitals mentioned above, several of them were able to get back to work once the infections were cleaned out and data restored from backups. The temporary disruptions caused by the compromised systems were kept to a minimum, as was the damage to the wallet, by a tested (and now proven) disaster response and recovery/backup plan. How long could your business afford to be disrupted by a ransomware attack? Could your business survive the loss of critical data? What about the reputation damage resulting from disclosing the attack to customers? If you thought a backup platform was expensive, consider the alternative. In the case of Hollywood Presbyterian, $17k was just the down payment on a huge hit to the wallet.
