The owners of the Telegram channels noted that scammers under the guise of advertising offers send malicious files.
" In particular, they can be represented by advertising managers of the GeekBrains educational platform", Nikita Mogutin, the co-founder of the Telegram channel Baza (more than 310,000 subscribers), wrote on Facebook. Owner of the Telegram channel Madonna (more than 9500 subscribers) Madonna Moore said that five scammers write to her a day. She also published the text of correspondence with a person who introduced himself as a representative of GeekBrains.
GeekBrains has received many complaints about fraud on behalf of the company and has already sent out warnings to agencies and bloggers, said Elena Toropina, head of the company's marketing department. In her opinion, the attack on the channels is connected with the growth of the online education industry, which spends a lot of money on advertising.
Kaspersky Lab reported that the attachments sent by the attackers contain a Trojan virus.
"If the victim runs the file, a program will be installed on the computer that will steal the accounts stored on it and provide fraudsters with hidden remote control of the Telegram channel", told Yaroslav Kargalev, deputy head of the Group-IB incident response center. According to him, scammers can also change the phone number in the channel's account to get full control over it.
Most often, channel theft is needed to publish links to malicious resources in the Telegram channel or to get a ransom, said Sergey Trukhachev, head of the special services unit of Infosecurity a Softline Company.
"The increase in the activity of scammers may be associated with the influx of new users to Telegram", noted Kargalev.
Telegram downloads have increased dramatically as WhatsApp has added a clause to its rules that allows users to share their personal data with Facebook. Moreover, the growing popularity of Telegram is due to the fact that supporters of Donald Trump, who was blocked in many social networks, have "flowed" there.
Telegram founder Pavel Durov called the sharp increase in the number of new users "the largest digital migration" in human history. In the first week of January, Telegram's monthly audience overcame the mark of 500 million active users.
Earlier, E Hacking News reported that Pavel Durov advised users to remove WhatsApp from smartphones. He called the WhatsApp application unsafe.
