Resistance is futile: Some Cisco security appliances are ticking time bombs of fail thanks to faulty resistors

After 18 months, they can just fall over. The fix is asking Borgzilla for a new one


Resistors, which cost a few cents apiece, are bricking pricey Cisco Adaptive Security Appliances (ASAs).

A Cisco field notice reveals that models ASA5508 and ASA5516 “might fail in operation, after 18 months or longer, due to a damaged component.”

“Due to a manufacturing process issue, some ASA5508 and ASA5516 security appliances might have a damaged resistor component,” the advisory added.

“Security appliances with a damaged resistor will function normally on installation and product failures are expected to increase over time beginning after the unit has been in operation for approximately 18 months. Once the security appliance has failed the unit will no longer function, will not boot, and is not recoverable.”

The firewalls’ power light will come on and shine green if everything's OK. If your box is borked, the status LED will go amber and blink. The 5508 unit costs about $700, and the 5516 around $3,000, so that’s a pretty pricey resistor failure.

Cisco’s fix for the mess is sending you a new appliance. Administrators in Asia, Argentina, Mexico, Venezuela, Colombia, Brazil, Mexico, Russia, Turkey and the UAE have been warned they may need to wait up to three months for their new kit to arrive. Cisco blames “importation regulations” for that delay.

The field notice includes a form to apply for replacement kit, and a link to Cisco’s serial-number-checker so you can make sure your ASA is one of the problem units.

Cisco’s also added its 8856 series IP phones and model 190 and 191 analog telephone adapters to the list of products impacted by an expired certificate SNAFU. Owners of the devices need to install new certs to avoid symptoms that Cisco’s advisory describes as including a “loss of voice communications, intermittent call interruptions, or non-deterministic endpoint behaviour.” ®

    Another terrible launch, but DICE is already working on improvements

    The RPG Greetings, traveller, and welcome back to The Register Plays Games, our monthly gaming column. Since the last edition on New World, we hit level cap and the "endgame". Around this time, item duping exploits became rife and every attempt Amazon Games made to fix it just broke something else. The post-level 60 "watermark" system for gear drops is also infuriating and tedious, but not something we were able to address in the column. So bear these things in mind if you were ever tempted. On that note, it's time to look at another newly released shit show – Battlefield 2042.

    I wanted to love Battlefield 2042, I really did. After the bum note of the first-person shooter (FPS) franchise's return to Second World War theatres with Battlefield V (2018), I stupidly assumed the next entry from EA-owned Swedish developer DICE would be a return to form. I was wrong.

    The multiplayer military FPS market is dominated by two forces: Activision's Call of Duty (COD) series and EA's Battlefield. Fans of each franchise are loyal to the point of zealotry with little crossover between player bases. Here's where I stand: COD jumped the shark with Modern Warfare 2 in 2009. It's flip-flopped from WW2 to present-day combat and back again, tried sci-fi, and even the Battle Royale trend with the free-to-play Call of Duty: Warzone (2020), which has been thoroughly ruined by hackers and developer inaction.

  • American diplomats' iPhones reportedly compromised by NSO Group intrusion software

    Reuters claims nine State Department employees outside the US had their devices hacked

    The Apple iPhones of at least nine US State Department officials were compromised by an unidentified entity using NSO Group's Pegasus spyware, according to a report published Friday by Reuters.

    NSO Group in an email to The Register said it has blocked an unnamed customers' access to its system upon receiving an inquiry about the incident but has yet to confirm whether its software was involved.

    "Once the inquiry was received, and before any investigation under our compliance policy, we have decided to immediately terminate relevant customers’ access to the system, due to the severity of the allegations," an NSO spokesperson told The Register in an email. "To this point, we haven’t received any information nor the phone numbers, nor any indication that NSO’s tools were used in this case."

  • Utility biz Delta-Montrose Electric Association loses billing capability and two decades of records after cyber attack

    A US utility company based in Colorado was hit by a ransomware attack in November that wiped out two decades' worth of records and knocked out billing systems that won't be restored until next week at the earliest.

    The attack was detailed by the Delta-Montrose Electric Association (DMEA) in a post on its website explaining that current customers won't be penalised for being unable to pay their bills because of the incident.

    "We are a victim of a malicious cyber security attack. In the middle of an investigation, that is as far as I’m willing to go," DMEA chief exec Alyssa Clemsen Roberts told a public board meeting, as reported by a local paper.
