AI Malware in PyPi dressed up as DeepSeek Lurks

In the Python Package Index ( PyPi), malicious packages have been discovered, but the code has been actually loaded with infostealers. Developers should proceed with caution because that’s likely not the only system loaded with false, malicious DeepSeek packages, according to experts.

Experts with Positive Technologies discovered the destructive items, labeled “deepseekai” and “deepseeek”, trying to trick engineers into thinking they were true.

” The attack targeted engineers, machine learning]ML] professionals, and ordinary AI fans who might be interested in integrating DeepSeek into their systems”, the in an examination.

The bill behind the assault, “bvk”, was created in June 2023 and sat dormant until the battle sprang to life on Jan. 29, according to the report. When executed, the researchers noted both “deepseeek” and “deepseekai” cut infostealers to steal sensitive information, including API tips, collection credentials, and rights.

The harmful PyPi packages have been deleted, but there’s proof they were saved 36 times using the pip package director and the bandersnatch mirroring tool, and 186 times using the browser, the researchers reported.

” Sometimes API keys aren’t leaked, they’re just plain stolen”, Tim Erlin, vice president of product at Wallarm says. ” This incident serves as an illustration of how attackers exploit the current news cycle.” Anytime you’re doing something popular, whether clicking on a link or installing a PyPi package, it’s best to approach the task with a healthy dose of skepticism”.

According to Mike McGuire, senior security solutions manager at Black Duck, that mindset can help developers prevent making similar cybersecurity mistakes.

Many developers missed the “red flag” that they were downloading packages from an account with a limited, poor reputation, and had their environment variables and secrets compromised as a result, according to McGuire.

Ironically given how advanced DeepSeek’s capabilities are touted to be, the attack itself was a fairly low-tech affair, Michael Lieberman, CTO at Kusari, notes.

Kusari points out that typosquatting attacks are popular because they work. A developer can easily type a word or use a name that sounds similar, and their application suddenly produces malicious code. Since the pool of potential victims is larger, popular or trendy technologies are particularly at risk.

In a surprising twist, the researchers discovered proof that the threat actors had used AI to create the malicious code.

” There are clear indications that the compromised code was written with AI assistance, providing a real-world example of AI being used for malicious intent”, Wallarm’s Erlin says.

Erlin adds that developers should anticipate the distribution of similar malicious packages among various platforms.

” Developers, with malintent or not, are heavily invested in using AI to be more efficient”. he adds. ” AI lets developers write more code, faster. We should anticipate that malicious code will grow at the same rate as code in general.

Developers must implement strong security practices throughout the software development lifecycle ( SDLC ), according to Raj Mallempati, CEO of BlueFlag Security, to protect their environments from these threats. That means using software composition analysis (SCA ) tools, as well as automated vulnerability scanning, limiting the use of unverified packages in developer environments, and threat intelligence monitoring.

According to Mallempati,” this recent incident emphasizes the need for developers to specifically guard against threats like OSS typosquatting.” The key here is to double check package names and verify package sources that originate from DeepSeek. Additionally, developers should turn on Github dependabot and other dependency scanning tools to prevent them from downloading illegal packages.
