Former Sysadmin Accused of Planting 'Time Bomb' In Company's Database (bleepingcomputer.com) 143

An anonymous reader writes: Allegro MicroSystems LLC is suing a former IT employee for sabotaging its database using a "time bomb" that deleted crucial financial data in the first week of the new fiscal year. According to court documents, after resigning from his job, a former sysadmin kept one of two laptops. On January 31, Patel entered the grounds of the Allegro headquarters in Worcester, Massachusetts, just enough to be in range of the factory's Wi-Fi network. Allegro says that Patel used the second business-use laptop to connect to the company's network using the credentials of another employee. While connected to the factory's network on January 31, Allegro claims Patel, who was one of the two people in charge of Oracle programming, uploaded a "time bomb" to the company's Oracle finance module. The code was designed to execute a few months later, on April 1, 2016, the first week of the new fiscal year, and was meant to "copy certain headers or pointers to data into a separate database table and then to purge those headers from the finance module, thereby rendering the data in the module worthless." The company says that "defendant Patel knew that his sabotage of the finance module on the first week of the new fiscal year had the maximum potential to cause Allegro to suffer damages because it would prevent Allegro from completing the prior year's fiscal year-end accounting reconciliation and financial reports."

      Allegro's IT staff discovered the sabotaged Oracle finance module on April 14, 2016. Ten days later, on April 24, the IT staffers found Patel's malicious code after comparing the current database with a copy from older backups.

      It sounds like they depend on the MAC address for access security, and not-a-one-of-them has ever heard of MAC spoofing. (Or a Pingles can for extending WiFi range to off of company property.)

        If all he needed was the mac address, then he didn't even need the laptop. He could have spoofed the Mac Address. Most likely there was additional network security which is why he needed the laptop. It could be a cert/key etc. too that was on the laptop which he couldn't spoof.

      It's not worth posting stories about these amateurs. Everyone knows you don't just delete random stuff, you introduce subtle errors that can be passed off as genuine mistakes, and which take years to fully manifest, way beyond the point where backups can help.

      • Your homepage is actually really great. There is however a broken link on the front page.
      • Of course, but you keep all your noxious code always in the stack, rendered inactive by a script that you bring in your USB stick, and manually execute every six months. Then when you are no longer there to execute the script...

        Much safer than having to hack the network to delete things and leaving a trail and all that. Of course it's a lot of work, and perhaps your wife is right, and if you had used all that work for the benefit of your company, perhaps they wouldn't have fired you.

          When someone leaves, I immediately nuke all of their account credentials, often before they even exit the building.

      Part four of this (about half way through it) has an example (about half way through it) of how ridiculous damage estimates for computer crime were "determined".
      http://www.mit.edu/hacker/hack... [mit.edu]
      Damage of $79,449 was determined (in itemised detail) for downloading a document that could be purchased in hard copy form for $13.

      Sadly the same sort of reasoning still applies.

    • How does one calculate the damages a company suffered by being rendered unable to generate financial reports?
      By the fine they get and by the time/efford they need to recover the data and finally deliver the report.

  • So the best evidence they have is the MAC address of the wifi adapter of the business laptop that wasn't returned. We all know how immutable that is.

    The article seems merely to be parroting the court documents that were filed by Oracle, leading to a one sided story. Just as likely Patel is being being thrown under the bus for someone else' screwup, or perhaps a case of industrial sabotage. Excuse me if I don't assume anything Oracle is alleging as true.

    • Simply depending on a MAC address alone would be an amateur move. A talented investigator will not rely on a single fingerprint. Instead, the professional will balance the reliability (e.g. resistance to tampering) and identifiablity of multiple fingerprints. For example, one will search logs for hostnames, UUIDs, usernames, etc. Amongst other things, this is what keeps the professional from getting (too) hung up on concluding that it was the user who's credentials were stolen.

        "This could also happen if they forgot to renew the software."

        Absolutely. The biggest time bomb of all might be simply to decline to share the file of license renewals. The company starts to feel the results of *that* after the admin is long gone. And all the warning messages go to the admin's closed account, or to a service account that nobody checks since he left.

        The problem is, the results are indistinguishable from the case where the admin passed the information to "transition management" prior to being outsourced, only to have them lose it, so he gives them his spare copy, and they lose that also, and then a few months down the road when appliances and software suddenly stop working, offshore management blames the former admins for the debacle(s).

        Don't ask me how I know this.
