Porting from Colt

Colt are still not porting and have not updated us as to the status.

They have updated their "cyber-incident" page (which isn't linked on their website and is set to prevent indexing by search engines) to say they are committed to transparency.

We also hear they have advised some Enterprise customers they will be unable to deliver new connectivity orders until 2026. We cannot confirm this, but if true it would be reasonable to assume that porting numbers out is not of a higher priority to them than new business.

We know Ofcom are aware and hope they will be asserting appropriate priorities and full disclosure.

27 days since Colt responded to their cyber-security incident which, after eventually admitting they have consistently down-played, they continue to be unable to process number ports. Please continue submitting them as we are queuing this side.

Colt continue to not process number ports despite down-playing the cyber-security incident which they initially responded to 21 days ago.

Colt are keen to emphasise on their status page (https://www.colt.net/status/) how this didn't affect customer systems. They have also marked their cyber-incident page at https://www.colt.net/go/cyber-incident/ to "noindex" to hide it from search engines, and it isn't linked anywhere on their website. None of them mention number portability either, which they continue to not do, despite us now being in day 16.

Colt have contacted us to say that "all port-in and port-out activities are currently on hold until next week, as we’re still working internally to stabilize the situation"

Colt are still not processing number ports.

Please continue to submit porting orders normally, we have a queue and are chasing them daily.

An excellent blog has been published documenting the events so far at https://doublepulsar.com/colt-technical-services-gets-ransomwared-via-sharepoint-initial-access-some-learning-points-617da7e27ebc

Colt are still not processing number ports.

Other than restating their status page to say this was a cybersecurity incident from day one (formerly an "IT issue"), and their compromised documents being mid-auction, there is no update here. Their porting desk appear to have stopped the daily updates and are still not processing orders.

There is no update here other than Colt's porting team have advised there will be no imports or exports "until further notice". We continue to queue POV and porting orders for them.

Colt are still unable to process number ports, we assume as a consequence of their well publicised cyber-attack. A list of compromised files, which is asserted to be the files compromised by the attacks is at (https://www.klos.com/~john/colt_filename_tree.txt)

This list contains a number of interoperability documents between Simwood and Colt. The list also contains documents that appear to be Number Portability Order Forms, although it is unclear as to whether these relate to Simwood customers. NPORs will contain some information about the Subscriber changing providers, e.g. name, address, and telephone numbers. Additionally, there is other information clearly of a sensitive nature on the list, but that does not, as far as we can tell, relate to Simwood and its customer’s relationships.

At this time, we understand that Colt are working to prevent further disclosure, however, this is all the detail we have at this time. Our customers should engage their Data Protection Officers regarding the consequences of the attack on Colt as a matter of urgency.

There is no news to report here although the now admitted attack is being actively reported on, e.g. https://www.bleepingcomputer.com/news/security/colt-telecom-attack-claimed-by-warlock-ransomware-data-up-for-sale/

Colt have now confirmed an ongoing cyber-incident (https://www.colt.net/status/). At the moment voice traffic on existing ported numbers seems unaffected.

Colt have advised that they are unable to complete any import or export porting orders until further notice. Their Status page (https://www.colt.net/status/) suggests an IT issue while online speculation (https://cyberplace.social/@GossiTheDog/115022343170487477) is of an undisclosed cyber attack. We will advise when we have further news.
