Welcome to Encrochat
The errors that led to arrests of criminals using Encrochat
The following is a none exhaustive list of various (and in some cases comical cases of failing basic security measures)
Josephcox wrote an exceptional article on how various Police agencies 'cracked' the network. The French Gendarmerie’s Centre for Combating Digital Crime (C3N) gained access to Encrochat’s servers, housed at the French data centre provider OVH in Roubaix in April 2020.

The French, working with the Dutch police and the UK’s NCA, were able to collect 'encrypted' messages from the Encrochat devices.
More than 32k users in 122 countries were exploited, regardless of whether the users were criminal or not, the Berlin court found.
Specialists at C3N collected the messages and passed them on to Europol, which packaged them up according to country of origin and shared them with police forces in Germany, the UK and other countries. This has led to a number of legal challenges to decide the legality of the case(s) GSTaBerlin
Observations
The following includes evidence collected from various social networks in which the seemingly arrested, and in some cases imprisoned are convinced the 'cracked' interception and subsequent takedown is 'illegal', and in the near future will be heard by a court in France to determine the legality of it parts of the case. A case heard in Berlin struck dow.

There is an golden cited piece of research by @the_grugq

This piece stresses a number of areas of fundamental areas of tradecraft expertise to master.
Not like this, an i swear Big Poppa (https://www.dailyrecord.co.uk/news/scottish-news/scots-criminal-gangs-face-carnage-25844782) was the first 'victim' i saw. Ironic.
BIG POPPA

Great t-shirt.
Toffeeforce

Stewart was arrested after he posted the photo on the encrypted messaging service EncroChat, via his handle “Toffeeforce.” Unbeknownst to him, the service had been cracked by police in Europe. From that, his palm and fingerprints were analyzed and police had their man
Carrothorn'/'Maidenbear', 'Mistersmallhead', 'Festiveape', and 'Shaggyfarmer

Key to the investigation was an image recovered of Atkinson drinking beer in his garden during the Covid lockdown.
It was sent from his device to a leading member of another drugs gang, which prompting confirmation that he was behind the nicknames and heading the drug conspiracy.

Nevermind, eh.
Alex Male

He was detained at Lisbon Airportafter arriving on a flight from Turkey where he had been refused entry, according to the National Crime Agency (NCA), which added Male to its most wanted appeal in January.
Lemonisland/Activegamer

Bryan Stephen Heffey, was found to be using the EncroChat handles 'Activegamer' and 'Lemonisland' to supply large quantities of heroin, cocaine and cannabis. Detectives found evidence of his drug dealing on his handles, with pictures he shared with other users showing blocks of cocaine and an estimated £16,000 of cash.
Fatso

Sources have confirmed that Mitchell used the alias 'Anthony Swanson' while living out of a middle-class address on Pollard Lane, Bradford in Yorkshire.
This was the same alias used by the former Gilligan gang member when he fled Ireland following the murder of Veronica Guerin.
According to sources, Mitchell also used the same bogus date of birth used previously - May 14, 1960 - for his 'Swanson' identity.
SneakySystem/Wackysilver
George Marsh was identified after sharing an image on his Encro device of his own hand holding a bag of drugs, from which his fingerprints were analysed.
Johnny Weed/DiorPaw
The court heard Digweed, of Harlech Road in Crosby, sent messages to other dealers referencing his kids and birthday parties he was planning for them, helping police to trace him when the Encrochat system was hacked. He also sent other messages allowing them to be sure of his identity. One image sent to him by another criminal showed a block of cannabis labelled “Johnny Weed.”
His response was: “HaHaHaHa lad who’s done that, its only missing dig out the name. My name is Johnny Digweed init.” Digweed was arrested in March 2021 and convicted in December of seven counts of conspiracy to supply drugs in addition to one count of money laundering.
TrustedBat
Ryan's operation came crashing down after he posed for a selfie. But his secret identity was exposed when police linked that account to a photo the 23-year-old had taken of himself and sent to an associate.
Nice.

Nice.
Headfluffy

He was unveiled as the user of an account with the handle Headfluffy because of one simple mistake - when arranging a deal with a wholesaler he actually gave the address of his Foxdene home in Ellesmere Port as a drop off point for the drugs he was buying.
Steven Strachan/FastSilver
The 49-year-old was identified as FastSilver partly because of the photos he sent to other users of his extensively renovated home on School Lane in Bidston. This included an image of him lazing in his yard, which had distinctive paving that allowed police to match it to the picture sent by the account.

Lovely paving tbh
AtomicMantis/Silky/James Duckworth
Prosecutors said notes on his phone suggested Duckworth was responsible for paying out more than £4m to associates on just one day last year.
Meanwhile photos showed £385,000 of cash - vacuum sealed for delivery - laid out in front of the fireplace of his family's home, along with kilos of Class A drugs opened for inspection. A password to his device combined his name with that of his partner and children. He told contacts his home was recognisable because of the white Jaguar outside.

Wise words.
“It is only very very stupid people who think the law is stupid. And avoid like the plague, loud attention seeking wannabe gangsters who are in it for the glory, to be a face, to be a name. They don't mean to fuck up. They just do.
