From Heart Attack to Hack Attack: Hackers Can Now Control Pacemakers

b2ap3_thumbnail_medical_device_hacks_400.jpg Medical technology has allowed for vast improvements in the way that conditions are treated. For example, the pacemaker allows some people with heart conditions to live longer and more comfortably. However, a European research team has concluded that even pacemakers are susceptible to being hacked, with deadly results.

The researchers made a note to describe the dangers of using implantable cardioverter defibrillators, from a hacking standpoint. Many modern pacemakers have the ability to communicate with other devices. While this capability is designed as a benefit to the patient, allowing the devices to be examined without an invasive surgical procedure, it can have dire consequences if hacked. If the patient is away from the doctor’s office within two hours, the pacemaker can still receive signals from other devices, thus making it vulnerable to a cyber attack.

Hackers can send a signal to the pacemaker that keeps the device from returning to “sleep mode,” which is what makes it vulnerable to exploitation. By analyzing the signals sent to the tested devices, researchers could spot various ways that a hacker would use this exploit. The results varied from draining the battery’s life to stealing personal data that may be stored on it. In other words, the hacker can make the patient’s life rather difficult by either turning off the device, or stealing data and using it to steal their identity. Hackers could even activate the pacemaker’s resuscitation shock without need, jolting the heart and making things difficult for the victim.

There are at least 10 different types of lifesaving devices that are vulnerable to this simple exploit. In fact, the hacker doesn’t necessarily need to know anything about the device itself. The reason why these devices are so vulnerable is thanks to the manufacturers not believing that pacemakers are clear targets of cybercriminals. This led them to release the devices without the IT security necessary to prevent these targeted attacks. The lesson learned: “Nobody will consider pacemakers a target,” is no excuse to use lackluster security.

Keep in mind that this study was conducted by researchers, rather than hackers. Still, have you ever considered the fact that your organization could be at serious risk? Some SMBs are under the impression that their small size means that they aren’t a target. However, most hacking incidents aren’t targeted events, and are instead massive campaigns meant to infect anything and anyone who happens to click on the wrong link. Furthermore, all businesses have some data that’s worth stealing, like employee records and financial credentials, and it needs to be protected properly.

This Hacker Messed With the Wrong Transportation Agency

b2ap3_thumbnail_san_francisco_transportation_hack_400.jpg While San Francisco residents might not be happy that they’ll again have to pay fares to ride the city’s rail system, the reason they again have to do so is understandable. Plus, it provides an excellent example of the importance of maintaining a backup and using complex passwords.

A hacker or group of hackers, operating under the moniker Andy Saolis, managed to halt the collection of fares by the San Francisco Municipal Transportation Agency (or Muni) by hacking their station computer system and introducing a strain of ransomware into it. As a result, Muni employees were unable to access their workstations and some of the agency’s systems were disabled.

However, the hacker claimed to have accomplished more, as ticketing kiosks across the city would only display “you hacked. ALL data encrypted.” The ransom demand for the decryption key was approximately $73,000 in Bitcoin. Despite the hacker’s apparent confidence in their accomplishment, Muni elected to not pay the ransom, deciding instead to restore their systems from a backup and allowing cybersecurity experts to strike back against the hacker, not just once, but twice.

Two independent vigilante hackers managed to access the email account of “Andy Saolis” to collect information that helped to stop the attack, both by correctly guessing the answer to the account’s security question. It would seem that the hacker(s) known as Andy Saolis had been active for a while, but had never before targeted anything other than private companies, which very well may have led to their downfall.

Once the attack was thwarted it came to light that seemingly no data, including that from Muni’s customer payment systems, had been accessed, despite the attack affecting 25 percent of Muni’s network. Saolis, unsurprisingly, gave a considerably different account online.

Claiming to have stolen data from the payment kiosks, as well as 30 gigabytes of data from Muni’s system on their employees, customers, and technical matters, Saolis wasn’t shy about casting himself (or themselves) in the light of the vigilante against an unjust system.

According to an email sent through Russian service Yandex.com, “They give Your Money and everyday Rich more! But they don’t Pay for IT Security and using very old system’s !”

Shortly after the attack ended, security experts were also able to establish that the emailer was based in Iran, and had gained access to the hacker’s servers.

Though Muni never had to pay a ransom for their data, this attack wasn’t cheap, costing them the combined total of the free rides they granted to commuters as their systems were compromised. However, this total would certainly be less than the actual cost of the Bitcoin ransom, and so a good general rule to follow is to never give in to a hacker’s possibly insincere demands.

On the topic of the hacker, whose password was guessed by two separate strangers, how weak must this password have been? While nobody should ever complain about a hacker being foiled, it goes to show how a complete stranger could find their way into your accounts if you aren’t being careful..

This case is far from over, as the Federal Bureau of Investigation and the U.S. Department of Homeland Security are still investigating the matter, which provides proof that public systems are still unable to be fully trusted.

There is a lot for SMBs to learn from this story. How confident are you in your IT security? If you feel it’s time for a security audit in order to determine how protected your business is from all kinds of threats, reach out to COMPANYNAME at PHONENUMBER.
