Leaked GitHub Python Token

Read Time:55 Second

Here’s a disaster that didn’t happen:

Cybersecurity researchers from JFrog recently discovered a GitHub Personal Access Token in a public Docker container hosted on Docker Hub, which granted elevated access to the GitHub repositories of the Python language, Python Package Index (PyPI), and the Python Software Foundation (PSF).

JFrog discussed what could have happened:

The implications of someone finding this leaked token could be extremely severe. The holder of such a token would have had administrator access to all of Python’s, PyPI’s and Python Software Foundation’s repositories, supposedly making it possible to carry out an extremely large scale supply chain attack.

Various forms of supply chain attacks were possible in this scenario. One such possible attack would be hiding malicious code in CPython, which is a repository of some of the basic libraries which stand at the core of the Python programming language and are compiled from C code. Due to the popularity of Python, inserting malicious code that would eventually end up in Python’s distributables could mean spreading your backdoor to tens of millions of machines worldwide!

U.S. Trades 5 Cybercriminals to Russia in Prisoner Swap

Read Time:4 Minute, 12 Second

Twenty-four prisoners were freed today in an international prisoner swap between Russia and Western countries. Among the eight Russians repatriated were five convicted cybercriminals. In return, Russia has reportedly released 16 prisoners, including Wall Street Journal reporter Evan Gershkovich and ex-U.S. Marine Paul Whelan.

Among the more notable Russian hackers released in the prisoner swap is Roman Seleznev, 40, who was sentenced in 2017 to 27 years in prison for racketeering convictions tied to a lengthy career in stealing and selling payment card data. Seleznev earned this then-record sentence by operating some of the underground’s most bustling marketplaces for stolen card data.

Once known by the hacker handles “Track2,” “Bulba” and “nCux,” Seleznev is the son of Valery Seleznev, a prominent member of the Russian parliament who is considered an ally of Vladimir Putin. U.S. prosecutors showed that for years Vinnik stayed a step ahead of the law by tapping into contacts at the Russian FSB, the successor agency to the Soviet KGB, and by periodically changing hacker handles.

But in 2014 Seleznev was captured by U.S. Secret Service agents, who had zeroed in on Seleznev’s posh vacation spot in The Maldives. At the time, the South Asian island country was a popular destination for Eastern Europe-based cybercriminals, who viewed it as beyond the reach of U.S. law enforcement.

In addition to receiving a record prison sentence, Seleznev was ordered to pay more than $50 million in restitution to his victims. That loss amount equaled the total losses inflicted by Seleznev’s various carding stores, and other thefts attributed to members of the hacking forum carder[.]su, a bustling cybercrime community of which Seleznev was a leading organizer.

Also released in the prisoner swap was Vladislav Klyushin, a 42-year-old Muscovite sentenced in September 2023 to nine years in prison for what U.S. prosecutors called a “$93 million hack-to-trade conspiracy.” Klyushin and his crew hacked into companies and used information stolen in those intrusions to make illegal stock trades.

Klyushin likewise was arrested while vacationing abroad: The Associated Press reported that Klyushin was captured in Switzerland after arriving on a private jet, and just before he and his party were about to board a helicopter to whisk them to a nearby ski resort.

Klyushin is the owner of M-13, a Russian technology company that contracts with the Russian government. According to prosecutors, M-13 offered penetration testing and “advanced persistent threat (APT) emulation.” As part of his guilty plea, Klyushin was also ordered to forfeit $34 million, and to pay restitution in an amount that was to be determined.

The U.S. government says four of Klyushin’s alleged co-conspirators remain at large, including Ivan Ermakov, who was among 12 Russians charged in 2018 with hacking into key Democratic Party email accounts.

Russia also welcomed home one of its most accomplished money launderers. Alexander Vinnik, 44, who was one of the operators of BTC-e, a large cryptocurrency exchange that helped launder crime proceeds tied to various ransomware groups.

In 2017, U.S. authorities seized BTC-e, charging Vinnik with operating an international money laundering scheme that included some 850,000 bitcoins stolen from cryptocurrency exchange Mt. Gox. In May 2024, Vinnik pleaded guilty to laundering more than $9 billion.

Vladimir Dunaev, 40, was one of the masterminds behind the Trickbot trojan, a crimeware-as-a-service platform that for many years was used by Russian cybercrime groups to install ransomware and siphon data from victims. Duanev was sentenced in January 2024 to five years and four months in prison.

The fifth convicted Russian sent back home this week is Maxim Marchenko, 52, who pleaded guilty in February 2024 to illicitly procuring large quantities of U.S.-made microelectronics on behalf of Russian clients in support of the war on Ukraine.

Marchenko admitted setting up a number of shell companies based in Hong Kong that were used to acquire the technology products that have military-grade applications, such as rifle scopes, night vision goggles and thermal optics.

Among the Americans freed by Russia were Wall Street Journal reporter Evan Gershkovich, 32, who has spent the last 16 months in a Russian prison on spying charges. Also released was Alsu Kurmasheva, 47, a Russian American editor for Radio Free Europe/Radio Liberty who was arrested last year; and Paul Whelan, 54, a former U.S. Marine arrested in 2018 and accused of spying.

The New York Times reports several others freed by Russia were German nationals, including German Moyzhes, a lawyer who was helping Russians obtain residence permits in Germany and other E.U. countries. The Times says Slovenia, Norway and Poland released four people accused of being Russian spies.

Reuters reports that Germany released Vadim Krasikov, an FSB colonel serving a life sentence there for murdering an exiled Chechen-Georgian dissident in a Berlin park.
