Edition ZDNet, with reference to the Bulgarian law enforcement officers, reports on the arrest of the Instakilla hacker (real name was not disclosed). The suspect is accused of hacking, extortion and selling information stolen from companies on the Internet. During searches in Plovdiv, several computers, smartphones, flash drives, as well as an unnamed amount of cryptocurrency were seized from the hacker.
Instakilla has been active since about 2017, although it only gained prominence last year. So, in the summer of 2019, it was Instakilla that leaked information stolen from the National Tax Administration of Bulgaria to the network, although it did not directly participate in the hacking itself.
In the fall of that year, a hacker compromised the official Comodo forums and then claimed responsibility for breaking into a number of Italian and Dutch forums for sex workers (prostitution is legal in these countries).
Instakilla this year associated with a major break-in the Stalker Online forums, from where he stole over 1.2 million user entries, which he then put up for sale on a hacker forum. On the same forum, the attacker had something like his own "store" where he sold stolen data from companies (including two unnamed Bulgarian organizations, a local hosting provider and an e-mail service). And in the end, Instakilla was banned from this forum for fraud.
As it is easy to understand from the above incidents, Instakilla mainly preferred to hack the vulnerable vBulletin forums, from where it stole databases. Also, the criminal had his own website, where he offered his hacking services to everyone.
It is now known that Instakilla was detained by the authorities for 72 hours.
